Description

WATER GENERATION DVICE AND SYSTEMS

The present invention relates to a water generation device and system, and more particularly, to a device and system for generating water by capturing moisture in the air using a heat pump and geothermal heat.

There are currently several devices available on the market that operate on the principle of cooling the surrounding air by means of an exchanger having a temperature below the dew point temperature, these devices are commonly referred to as dehumidifiers, and the water vapor is removed from the air by condensing inside the device.

The main technology used in these dehumidifiers is a heat pump system, which is a technology used to move heat from a specific location to another location.

In conventional heat pump systems, moisture may condense during heat exchange, and this moisture is simply discarded.

Recently, devices that generate water using the above heat pump system have been developed, but they result in high energy consumption and there is a problem that water is not generated or excessive water is generated depending on the surrounding weather and environment.

The filter unit (231) may include a filter that filters out foreign substances from the outside air, and the air flow unit (240) may include a fan that sucks air from the front and flows it to the rear. The filter unit (231) and the air flow unit (240) may be arranged in the first chamber (200). The air flow unit (240) may be provided with a pair of air flow units (240). The pair of air flow units (240) may include a front air flow unit (240) and a rear air flow unit (240) that are arranged to be spaced apart from each other in the front-back direction in the first chamber (200). The front air flow unit (240) may be arranged in the air inlet (230) together with the filter unit (231) and may be arranged at the rear of the filter unit (231). The rear air flow unit (240) may be positioned at the rear end of the first chamber (200) and may be positioned rearward of the second heat exchange unit (220).

The rear end of the first chamber (200) and the front end of the second chamber (500) may be connected through a duct. The internal volume of the duct may decrease from the front end to the rear end. Through this, the air in the first chamber (200) may be quickly moved to the second chamber (500).

When a pair of air flow units (240) are driven, the outside air is introduced into the first chamber (200) through the filter unit (231) and the front air flow unit (240), and then moves rearward while passing through the first heat exchange unit (210), the second heat exchange unit (220), and the rear air flow unit (240), and then is introduced into the front end of the second chamber (500) through the duct, and then moves rearward while passing through the water generation unit (510), and then exchanges heat with the water generation unit (510), and then is discharged to the outside through the rear end of the second chamber (500). This flow of air passing through the first chamber (200) and the second chamber (500) of the air flow system may be referred to as the third flow.

The compressor (100) compresses the first fluid at high temperature and high pressure, and can be connected to the second heat exchanger (600) and the first chamber (200).

The first chamber (200) may include a first heat exchange unit (210) through which the first fluid passes, a second heat exchange unit (220) through which the second fluid passes, and an air inlet unit (230) through which external air is introduced.

That is, air introduced into the air inlet (230) can pass through the first heat exchanger (210) and then be introduced into the second heat exchanger (220), and then move to the second chamber (500).

The first heat exchange unit (210) receives the first fluid at high temperature and high pressure from the compressor (100) and releases heat energy to the air introduced from the air introduction unit (230). The first heat exchange unit (210) may have a temperature of 40°C or more and 150°C or less, and preferably, may have a temperature of 50°C or more and 100°C or less. The first heat exchange unit (210) heats the external air introduced into the first chamber (200) to a constant temperature, thereby minimizing the influence of external weather and environment, thereby enabling stable water production.

In addition, the second heat exchange unit (220) absorbs the heat energy of air, into which the low-temperature second fluid flows from the geothermal unit (700) and which has been raised to a constant temperature through the first heat exchange unit (210). The second heat exchange unit (220) may have a temperature of 5 degrees or more and 30 degrees or less, and preferably, may have a temperature of 10 degrees or more and 20 degrees or less. The second heat exchange unit (220) lowers the temperature of air that passes through the first heat exchange unit (210) and moves to the second chamber (500), thereby allowing the water generation unit (510) to smoothly condense moisture contained in the air of the second chamber (500) to produce water.

When the first fluid passing through the expansion valve (400) flows into the water generating unit (510), and the air passing through the first chamber (200) flows into the second chamber (500) and passes around the water generating unit (510), the temperature of the water generating unit (510) is relatively lower than the temperature of the surrounding air of the water generating unit (510), so that water vapor in the surrounding air can be liquefied in the water generating unit (510) to generate water, and the water thus generated can be stored in the water storage tank of the water generating unit (510).

The second heat exchanger (600) can receive the fluid of an external system (not shown) and the first fluid that has passed through the water generating unit (510), and heat exchange can occur between the first fluid and the fluid of the external system.

The geothermal area (700) can utilize geothermal energy, which is an environmentally friendly renewable energy source, and can be located within 300 m from the ground and have a temperature of 5 degrees or more and 30 degrees or less.

Accordingly, the second fluid can absorb heat energy in the first heat exchange unit (210) and the first heat exchanger (300), and release heat energy in the geothermal unit (700).

The water generating device (1) according to the first embodiment of the present invention can produce water stably by minimizing the influence of the surrounding weather and environment by heating the outside air to a constant temperature by the first heat exchanger (210) of the first chamber (200).

In addition, the present invention can be applied to existing equipment using a heat pump, thereby optimizing economic costs.

In addition, the natural geothermal heat used in the geothermal section (700) is distributed in any region and is easy to collect, so it can be applied to various environments and is economically efficient.

The internal volume of the first chamber (200) can be formed to be constant from the front end to the rear end of the first chamber (200). That is, the first chamber (200) in FIG. 3 (a) can be formed to have a constant vertical width from the left end to the right end.

Referring to drawing (b) of FIG. 3, the internal volume of the first chamber (200) may be formed in a form in which it gradually decreases in the same direction as the air flow direction from the first heat exchange unit (210). Specifically, the internal volume of the first chamber (200) may be formed to be constant from the front end of the first chamber (200) to the rear end of the first heat exchange unit (210), and may be formed to be gradually decreased from the rear end of the first heat exchange unit (210) to the rear end of the first chamber (200). That is, the first chamber (200) in drawing (b) of FIG. 3 may be formed to have a constant vertical width from the left end to the rear end of the first heat exchange unit (210), and may be formed to have a gradually decreased vertical width from the rear end of the first heat exchange unit (210) to the right end.

When the cross-sectional area of one side of the duct is greater than the cross-sectional area of the other side of the duct, an internal volume of the duct may be formed in a form that gradually decreases from one side of the duct to the other side of the duct. When the cross-sectional area of one side of the duct is equal to the cross-sectional area of the other side of the duct, an internal volume of the duct may be formed in a constant form from one side of the duct to the other side of the duct.

The filter unit (231) can remove contaminants to obtain drinkable water from the water generating unit (510), and air introduced into the first chamber (200) can flow smoothly into the second chamber (500) by the air flow unit (240) and the shape of the first chamber (200) and the duct (250).

FIG. 4 is a drawing showing a water generating device according to the second embodiment of the present invention.

Here, the same configuration as that of the water generating device (1) according to the first embodiment of the present invention described above is given the same drawing reference numerals, and a detailed description thereof is omitted, and only the differences are described.

Referring to FIG. 4, it can be seen that the water generating device (2) according to the second embodiment of the present invention is different from the water generating device (1) according to the first embodiment of the present invention described above.

That is, the water generating device (2) according to the second embodiment of the present invention may further include a first valve (800), a third heat exchanger (520), a tenth flow path (931), and an eleventh flow path (932) compared to the water generating device (1) according to the first embodiment of the present invention described above.

The first valve (800) may be placed on the first urea (911) and may be placed between the compressor (100) and the first heat exchanger (210).

The third heat exchanger (520) may be placed in the second chamber (500). The third heat exchanger (520) may be provided separately from the heat exchanger of the water generation unit (510) to exchange heat with the water generation unit (510), or may be formed integrally with the heat exchanger of the water generation unit (510). When the third heat exchanger (520) is formed integrally with the heat exchanger of the water generation unit (510), the third heat exchanger (520) may be the heat exchanger of the water generation unit (510).

The 10th flow path (931) can connect the first valve (800) and the third heat exchanger (520). That is, the first valve (800) and the third heat exchanger (520) can be connected through the 10th flow path (931). However, if the third heat exchanger (520) is formed integrally with the heat exchanger of the water generation unit (510), the 10th flow path (931) can connect the first valve (800) and the heat exchanger of the water generation unit (510). That is, if the third heat exchanger (520) is formed integrally with the heat exchanger of the water generation unit (510), the first valve (800) and the heat exchanger of the water generation unit (510) can be connected through the 10th flow path (931).

That is, the third heat exchanger (520) and the second flow path (912) can be connected through the eleventh flow path (932). However, when the third heat exchanger (520) is formed integrally with the heat exchanger of the water generation unit (510), the eleventh flow path (932) can connect the heat exchanger of the water generation unit (510) and the second flow path (912). That is, when the third heat exchanger (520) is formed integrally with the heat exchanger of the water generation unit (510), the heat exchanger of the water generation unit (510) and the second flow path (912) can be connected through the eleventh flow path (932).

The heat exchange capacity of the third heat exchange unit (520) is formed smaller than the heat exchange capacity of the heat exchanger of the water generation unit (510), so that moisture contained in the air of the second chamber (500) can be condensed into water by the heat exchanger of the water generation unit (510). In addition, the first valve (800) can be used to melt the frost by opening the 10th flow path (931) only when frost has formed on the heat exchanger of the water generation unit (510) to release heat energy from the third heat exchange unit (520).

When the first valve (800) opens both the tenth flow path (931) and the first flow path (911), the first fluid from the compressor (100) can flow into both the third heat exchange unit (520) and the first heat exchange unit (210). That is, when the first valve (800) opens both the tenth flow path (931) and the first flow path (911), a portion of the first fluid from the compressor (100) can flow into the third heat exchange unit (520) through the tenth flow path (931), and the remainder of the first fluid from the compressor (100) can flow into the first heat exchange unit (210) through the first flow path (911).

In addition, when the first valve (800) opens the 10th flow path (931) and closes the first flow path (911), the first fluid coming from the compressor (100) can all flow into the third heat exchange unit (520). That is, when the first valve (800) opens the 10th flow path (931) and closes the first flow path (911), the first fluid coming from the compressor (100) can all flow into the third heat exchange unit (520) through the 10th flow path (931).

Of course, if the third heat exchanger (520) is formed integrally with the heat exchanger of the water generation unit (510), when the first valve (800) opens both the tenth flow path (931) and the first flow path (911), the first fluid from the compressor (100) can flow into both the heat exchanger of the water generation unit (510) and the first heat exchanger (210). That is, when the first valve (800) opens both the tenth flow path (931) and the first flow path (911), a portion of the first fluid from the compressor (100) can flow into the heat exchanger of the water generation unit (510) through the tenth flow path (931), and the remainder of the first fluid from the compressor (100) can flow into the first heat exchanger (210) through the first flow path (911).

In addition, when the third heat exchanger (520) is formed integrally with the heat exchanger of the water generation unit (510), when the first valve (800) opens the tenth passage (931) and closes the first passage (911), the first fluid from the compressor (100) can all flow into the heat exchanger of the water generation unit (510). That is, when the third heat exchanger (520) is formed integrally with the heat exchanger of the water generation unit (510), when the first valve (800) opens the tenth passage (931) and closes the first passage (911), the first fluid from the compressor (100) can all flow into the heat exchanger of the water generation unit (510) through the tenth passage (931).

FIG. 5 is a drawing showing a water generating device according to a third embodiment of the present invention.

Here, the same configuration as that of the water generating device (1) according to the first embodiment of the present invention described above is given the same drawing reference numerals, and a detailed description thereof is omitted, and only the differences are described.

Referring to FIG. 5, it can be seen that the water generating device (3) according to the third embodiment of the present invention is different from the water generating device (1) according to the first embodiment of the present invention described above.

That is, the water generating device (3) according to the third embodiment of the present invention may further include a first valve (800), a third heat exchanger (520), a tenth flow path (931), and an eleventh flow path (932) compared to the water generating device (1) according to the first embodiment of the present invention described above.

The first valve (800) may be placed on the second duct (912) and may be placed between the first heat exchanger (210) and the first heat exchanger (300).

The third heat exchanger (520) may be placed in the second chamber (500). The third heat exchanger (520) may be provided separately from the heat exchanger of the water generation unit (510) to exchange heat with the water generation unit (510), or may be formed integrally with the heat exchanger of the water generation unit (510).

The 10th flow path (931) can connect the first valve (800) and the third heat exchanger (520). That is, the first valve (800) and the third heat exchanger (520) can be connected through the 10th flow path (931). However, if the third heat exchanger (520) is formed integrally with the heat exchanger of the water generation unit (510), the 10th flow path (931) can connect the first valve (800) and the heat exchanger of the water generation unit (510). That is, if the third heat exchanger (520) is formed integrally with the heat exchanger of the water generation unit (510), the first valve (800) and the heat exchanger of the water generation unit (510) can be connected through the 10th flow path (931).

The eleventh flow path (932) can connect the third heat exchanger (520) and the second flow path (912). One end of the eleventh flow path (932) can be connected to the third heat exchanger (520), and the other end of the eleventh flow path (932) can be connected to the second flow path (912) arranged between the first valve (800) and the first heat exchanger (300). That is, the third heat exchanger (520) and the second flow path (912) can be connected through the eleventh flow path (932). However, when the third heat exchanger (520) is formed integrally with the heat exchanger of the water generation unit (510), the eleventh flow path (932) can connect the heat exchanger of the water generation unit (510) and the second flow path (912). One end of the 11th flow path (932) can be connected to the heat exchanger of the water generating unit (510), and the other end of the 11th flow path (932) can be connected to the second flow path (912) arranged between the first valve (800) and the first heat exchanger (300).

And, when the first valve (800) is opened by the user's operation or the control unit (not shown), the first fluid from the first heat exchange unit (210) flows into the third heat exchange unit (520), and the third heat exchange unit (520) can release heat energy to the heat exchanger of the water generation unit (510). The heat exchange capacity of the third heat exchange unit (520) is formed smaller than the heat exchange capacity of the heat exchanger of the water generation unit (510), so that moisture contained in the air of the second chamber (500) can be condensed into water by the heat exchanger of the water generation unit (510). In addition, the first valve (800) can be used to melt the frost by opening the 10th flow path (931) only when frost has formed on the heat exchanger of the water generation unit (510) to release heat energy from the third heat exchange unit (520).

When the first valve (800) opens both the 10th flow path (931) and the second flow path (912), the first fluid from the first heat exchanger (210) can flow into both the third heat exchanger (520) and the first heat exchanger (300). That is, when the first valve (800) opens both the 10th flow path (931) and the second flow path (912), a portion of the first fluid from the first heat exchanger (210) can flow into the third heat exchanger (520) through the 10th flow path (931), and the remainder of the first fluid from the first heat exchanger (210) can flow into the first heat exchanger (300) through the second flow path (912).

In addition, when the first valve (800) opens the 10th flow path (931) and closes the second flow path (912), the first fluid coming from the first heat exchange unit (210) can all flow into the third heat exchange unit (520). That is, when the first valve (800) opens the 10th flow path (931) and closes the second flow path (912), the first fluid coming from the first heat exchange unit (210) can all flow into the third heat exchange unit (520) through the 10th flow path (931).

Of course, if the third heat exchanger (520) is formed integrally with the heat exchanger of the water generation unit (510), when the first valve (800) opens both the tenth flow path (931) and the second flow path (912), the first fluid from the first heat exchanger (210) can flow into both the heat exchanger of the water generation unit (510) and the first heat exchanger (300). That is, when the first valve (800) opens both the tenth flow path (931) and the second flow path (912), a portion of the first fluid from the heat exchanger (210) can flow into the heat exchanger of the water generation unit (510) through the tenth flow path (931), and the remainder of the first fluid from the first heat exchanger (210) can flow into the first heat exchanger (300) through the second flow path (912).

In addition, when the third heat exchanger (520) is formed integrally with the heat exchanger of the water generation unit (510), when the first valve (800) opens the tenth passage (931) and closes the second passage (912), the first fluid from the first heat exchanger (210) can all flow into the heat exchanger of the water generation unit (510).

According to the water generating device (2) according to the second embodiment of the present invention illustrated in FIG. 4 and the water generating device (3) according to the third embodiment of the present invention illustrated in FIG. 5, compared to the water generating device (1) according to the first embodiment of the present invention illustrated in FIG. 1, by adding a third heat exchanger (520) or additionally providing the first fluid at a high temperature to the heat exchanger of the water generating device (510), frost that may be formed in the water generating device (510) can be removed, and an environment requiring relatively high heat can be formed with the structure of FIG. 5, and an environment requiring relatively low heat can be formed with the structure of FIG. 4. That is, energy can be used efficiently by selectively applying the structure of FIG. 4 or FIG. 5 depending on the surrounding environment.

The first valve (800), the tenth flow path (931), the third heat exchanger (520), and the eleventh flow path (932) illustrated in FIGS. 4 and 5 can constitute a defrosting system through which the first fluid flows.

Here, the same configuration as that of the water generating device (1) according to the first embodiment of the present invention described above is given the same drawing reference numerals, and a detailed description thereof is omitted, and only the differences are described.

Referring to FIG. 6, it can be seen that the water generating device (4) according to the fourth embodiment of the present invention is different from the water generating device (1) according to the first embodiment of the present invention described above.

That is, the water generating device (4) according to the fourth embodiment of the present invention may further include an external system (100), a 12th flow path (941), a 13th flow path (942), a 14th flow path (943), and a 15th flow path (944) compared to the water generating device (1) according to the first embodiment of the present invention described above.

That is, the first heat exchanger (300) and the first external heat exchanger of the external system (100) can be connected through the 15th flow path (944).

When the external system (1000) is driven, the external fluid may be heat-exchanged in the first external heat exchanger of the external system (1000), and then may flow through the 12th flow path (941), the second heat exchanger (600), the 13th flow path (942), the second external heat exchanger of the external system (1000), the 14th flow path (943), the first heat exchanger (300), and the 15th flow path (944) and then back to the first external heat exchanger of the external system (100). This flow of the external fluid of the external system (1000) may be referred to as the fourth flow.

The first fluid that has passed through the heat exchanger of the water generating unit (510) and the external fluid that has passed through the first external heat exchanger of the external system (1000) can be introduced into the second heat exchanger (600), and the first fluid that has passed through the heat exchanger of the water generating unit (510) and the external fluid that has passed through the first external heat exchanger of the external system (100) can undergo heat exchange in the second heat exchanger.

Therefore, the water generating device (4) according to the fourth embodiment of the present invention is connected to an external system (100) and can be utilized together, thereby optimizing economic costs.

The flow of the first fluid may be referred to as the first flow, the flow of the second fluid may be referred to as the second flow, the flow of the external air may be referred to as the third flow, and the flow of the external fluid may be referred to as the fourth flow. The first flow, the second flow, the third flow, and the fourth flow may only exchange heat without exchanging materials with each other.

Additionally, the first flow, the second flow, and the third flow can simultaneously exchange heat in at least one of the water generation system configurations, and preferably, the heat exchange can simultaneously occur in the first chamber (200).

The first flow and the second flow flowing into the first chamber (200) may have different temperatures, and at this time, the temperature of the first flow may be higher than the temperature of the second flow.

In addition, since the third flow passes through the first heat exchange unit (210) and flows into the second heat exchange unit (220), it can enter the second heat exchange unit (220) while being heated to a higher temperature in the first heat exchange unit (210) than in the second heat exchange unit (220).

The first flow flowing into the second chamber (500) enters the water generating unit (510) and can absorb the thermal energy of the third flow passing through the water generating unit (510).

At this time, as the heat energy of the third flow is released, some of the third flow may be liquefied and captured and stored in the water storage tank of the water generating unit (510) placed in the second chamber (500).

The first chamber (200) may include at least a portion of the first flow, the second flow, and the third flow. The first chamber (200) may include a first heat exchange unit (210) from which thermal energy of the first flow is released, a second heat exchange unit (220) from which thermal energy of the second flow is absorbed, and an air inlet unit (230) from which the third flow starts. The third flow may pass through the first heat exchange unit (210) and flow into the second heat exchange unit (222). The first heat exchange unit (210) and the second heat exchange unit (220) may have different temperatures.

The first heat exchanger (300) can include at least a portion of the first flow and the second flow. In the first heat exchanger (300), heat energy can be exchanged between the first flow and the second flow. The geothermal unit (700) can release heat energy of the second flow to reduce the temperature of the second fluid.

The second chamber (500) may include a water generating unit (510) in which heat energy is absorbed by the first flow, and at least a portion of the first flow and the third flow. Water may be generated as the third flow passes through the water generating unit (510).

By means of the first valve (800), the flow of the first fluid in the 10th flow (931) and the 11th flow (931) branched from the heat pump system may be referred to as the 1-1 flow, and the 1-1 flow may pass through the 3rd heat exchanger (520) or the heat exchanger of the water generation unit (510) to release heat energy.

The above defrosting system including the above-mentioned 1-1 flow can be implemented by the user's operation, and can be implemented by the system itself according to the judgment of the control unit (not shown).
