Description

Healthy and comfortable energy-saving air conditioner and method for treating air

The invention relates to a healthy and comfortable energy-saving air conditioner, in particular to an air conditioner capable of independently adjusting the humidity and temperature of air, and belongs to the technical field of refrigeration. It also deals with the treatment of air. Background technique

It is well known that the use of air conditioners in hot climates can produce a cool, refreshing comfort that is caused by the fact that the air conditioner reduces the temperature and humidity of the environment. Conventional air conditioners mainly focus on cooling the air. While lowering the temperature, the lower surface temperature of the evaporator is used to dehumidify the flowing air. In fact, dehumidification is only a secondary function of the air conditioner. When the conventional air conditioner dehumidifies the air, the dehumidification condensation temperature can only follow the outlet air temperature. The temperature of the outlet air directly affects the dehumidification effect. In hot weather, the cooling power is limited to make the outlet air temperature high, resulting in insufficient dehumidification. . In low-temperature weather, especially in the wet and cold season, dehumidification by air conditioners will result in lower indoor temperatures. For example, in the cold season, in order to reduce the air humidity inside the vehicle and prevent the windshield condensation from affecting the line of sight, the air needs to be dehumidified. However, this will result in a lower temperature inside the car, and it can only open a large warm air to keep out the cold. Therefore, the contradiction between cooling and blowing hot air in the same space greatly increases the energy consumption. This problem has not been solved yet.

Reducing humidity is an important part of improving air quality and is important for health, comfort and energy efficiency. The body heat is mainly through the evaporation of sweat and heat conduction. When the water content of the air is reduced, the vapor pressure of the air is reduced, which promotes the body's perspiration and heat dissipation. When the temperature is 30 °C and the relative humidity is 40%, people will feel quite comfortable. When the temperature is 28 °C and the relative humidity is 80%, it will make people feel uncomfortable. For comfort, the effect of humidity is no less than the temperature. For the air conditioner, the dehumidification function is positioned as "sub-function". .

According to the World Health Organization, people feel most comfortable in an air environment with a relative humidity of 40-60%. The existing air-conditioning technology does not pay enough attention to air humidity, and only focuses on cooling to achieve people's comfort. Actually, The air environment with a slightly lower humidity and moderate temperature is more conducive to the body's perspiration and heat dissipation. Comfort will be better and healthier, especially for people with weak health, which can reduce the occurrence of "air conditioning disease". The invention solves the problem that the condensation temperature and the outlet air temperature of the air conditioner are mutually restrained, and the temperature and humidity of the air can be independently adjusted to achieve the optimal health and comfort environment, and further

A method for treating air in a healthy and comfortable energy-saving air conditioner, comprising: the following steps: 1) pre-cooling air entering from the outside; 2) condensing and precipitating the pre-cooled air; 3) depositing condensation The air after the water droplets separates the water mist through the water mist barrier net or the water baffle; 4) the air passing through the water mist barrier mesh is reheated; 5) the air that has exited the outside air is adjusted to a desired temperature and then flows out.

The invention relates to a method for treating air in a healthy and comfortable energy-saving air conditioner, which comprises the following steps: 1) pre-cooling air entering from the outside through an intake passage; 2) passing pre-cooled air through a region surrounding the dehumidifying heat-conducting tube Condensation and precipitation of water droplets; 3) separating the air from which the water droplets are condensed and separated by a water mist barrier net; 4) re-heating the air passing through the water mist barrier net through the return air passage; 5) passing through the air outlet heat pipe The air that is going to be outside is adjusted to the required temperature and then flows out.

The above technical solution has such technical effects:

1. The dehumidification heat pipe is responsible for the air dehumidification task, and the air heat exchange path is lengthened. The air preheating step is added through the air inlet channel, and the air can obtain a lower condensation temperature at the same evaporation temperature. Degree, precipitation of more water, solves the problem of insufficient dehumidification caused by the large temperature difference between the air cooler and the over-wind when dehumidification in high temperature climate. If the dehumidification and cooling are carried out with a refrigerant of about 10 °C, the ideal temperature and humidity can be satisfied, and the energy efficiency ratio of the refrigerator can be improved, and electricity consumption can be saved.

3. The water-gas isolation net or the water-blocking plate effectively prevents the air from flowing into the return air passage, and brings the dew and the water mist suspended in the air to further improve the dehumidification effect. Moreover, the humid isolation net can be better filtered. The tiny particles in the air increase the cleanliness of the air, and the condensate can carry the particles out through the drain. The filter does not need to be cleaned frequently.

4. The densely adjacent inlet and return air passages in the combined evaporator enable the inflow and outflow to achieve quasi-reverse flow in most areas to achieve efficient heat exchange, realizing rapid sensible heat transfer between the incoming and outgoing air, without externally providing In the case of energy, the air entering and leaving the combined evaporator is separately pre-cooled and reheated, reducing the energy consumed by the sensible heat change of the air during dehumidification, reducing the load on the refrigeration compressor, and saving electricity. .

5. This technology changes the existing processing flow of "into the wind, cooling down, dehumidification, and out of the wind" to

The process of "intake air, pre-cooling, independent condensation, dehumidification, water vapor separation, heat recovery, independent temperature regulation - air outlet" solves the problem of the air conditioning temperature and the condensation temperature required for dehumidification in the conventional air conditioning technology. The temperature of the outlet air and its temperature during the dehumidification stage can be independently controlled.

6. The air outlet heat pipe and the dehumidification heat pipe can be independently assigned to different heat exchange circulation loops respectively, and the outlet heat pipe can cool or warm the air outlet, and realize the air by controlling the flow of the heat exchange medium respectively.

The structure of the technology is simple, the number of main components of the traditional air conditioner is maintained, the pipeline structure is simple, the combined evaporator is small in size, and the volume of the conventional evaporator is close to that of the conventional evaporator. The repellent air conditioner can maintain the original external size, and the product can be manufactured.

working principle:

The following mainly describes the treatment method, flow and related principles of the present invention for air humidity and temperature, and the differences and advances thereof with conventional techniques.

The health and comfort energy-saving air conditioner of the invention is driven by a refrigeration compressor, and the refrigerant enters through the dehumidification heat pipe of the combined evaporator through the throttle valve, and flows from the bottom to the top to reach the high outlet, and then divides into two paths, and all the way enters through the room temperature regulating valve. The tuyere heat pipe, the other way through the bypass valve and the outlet of the heat pipe outlet of the air outlet merges into the refrigeration compressor. The indoor air is driven by the fan, and the total air inlet enters the air intake passage through the respective air inlets in the air inlet hood, flows from the top to the bottom through the heat sink and the dehumidification heat pipe, reaches the defogging chamber, and then enters the air return through the water mist barrier network. The passage flows from the bottom to the top through the dehumidification heat pipe and its peripheral fins, and then flows through the air outlet heat pipe and its peripheral fins, and then flows out from the return air outlet, and finally flows out through the air outlet cover from the total air outlet. The air in each of the intake passages in the combined evaporator flows from top to bottom, and the air flowing from the bottom to the top through the return air passage first generates heat exchange through the passage wall, and then generates heat from the refrigerant flowing from the bottom to the top of the dehumidification heat transfer tube. The exchange makes the internal air temperature of the combined evaporator gradually decrease from top to bottom, and the temperature above the indoor air is close to the surface temperature of the dehumidification heat pipe.

The heat pipe and the expansion metal pipe section which traverse the intake passage and the return air passage cause turbulence in the air flowing inside, further improving the heat exchange efficiency of the incoming and outgoing air.

The densely adjacent inlet and outlet air passages in the combined evaporator enable high-efficiency heat exchange through large-area cross-convection of the inflow and outflow air through the diagonally distributed air inlet and outlet, thereby realizing rapid transfer of sensible heat between the incoming and outgoing air, and the combined evaporator The air entering and exiting is pre-cooled and reheated, respectively.

The air is contacted by the air inlet passage from the top to the bottom to contact the heat sink and the dehumidification heat pipe, and the temperature thereof is gradually lowered. When the temperature is lower than the saturated dew point of the water vapor, the super-saturated water in the air is separated from the air.

The water separated from the air changes from a gaseous state to a liquid state, and some of the water droplets flow into the bottom of the demisting chamber through the drain. Exhausted, but some will be suspended in the air in the form of a mist. If this part of the water mist is not treated, it is easy to follow the air back to the room.

In order to prevent the water mist formed in the defogging chamber from being smashed, a water mist barrier net or a water baffle is arranged in the demisting chamber, so that the air that is folded back from the intake passage to the return air passage must flow through the barrier net in the air. When the water mist meets the low-temperature barrier net, it will form a hanging bead to flow down, effectively preventing the water mist from coming out with the air.

The air after cooling and defogging is folded back from the defogging chamber from bottom to top into each return air passage. Since the temperature of the combined evaporator gradually rises from bottom to top, the air will absorb the air through the passage wall when flowing upward from below the return air passage. The heat of the air in the channel gradually recovers the temperature. The temperature of the heat exchange is slightly lower than the room temperature due to the heat exchange temperature difference. If the air needs to be further cooled, the refrigerant flow rate of the heat pipe of the air outlet is controlled by the room temperature regulating valve, and the air can be discharged according to the need. Re-cool down and adjust to the appropriate outlet temperature. By controlling the throttle valve to control the refrigerant flow rate or the evaporation temperature, the condensation condensation temperature can be controlled to adjust the dehumidification amount. By controlling the ratio of the refrigerant flow rate between the room temperature regulating valve and the bypass valve, the outlet air temperature can be flexibly controlled, and the air outlet of the air conditioner can be flexibly controlled. Temperature and humidity can be controlled independently.

Since the flow path of the refrigerant first passes through the dehumidifying heat pipe and then reaches the heat pipe of the air outlet, the refrigerant consumes a certain amount of cooling during the dehumidification stage. Therefore, the temperature of the refrigerant when reaching the heat pipe of the air outlet is not lower than before. The temperature of the heat pipe of the tuyere is not lower than the temperature of the dehumidifying heat pipe, and the temperature of the air forming the defogging chamber is relatively lowest in all areas. The air vapor passing through the return air passage to the last air is not saturated. There will be no condensation, and there will be no possibility of water mist or water droplets.

When the indoor air flows through the intake passage near the dehumidifying heat-conducting pipe, it has absorbed most of the cooling air that has been cooled out from the return air passage and then returned to the air. Before the dehumidifying heat-conducting pipe, the air is sufficiently pre-cooled, flowing around the dehumidifying heat-conducting pipe. After the area, the temperature difference from the surrounding heat pipe and the surface of the heat sink is much less than that of the conventional air conditioner, and the condensation temperature obtained by the air is lower, so that the condensation condition is greatly improved. In the case of the same evaporation temperature and the same amount of excess air, the present invention The dehumidification efficiency of the conventional air conditioner is significantly improved.

The air outlet temperature of the traditional air conditioner is generally 14 ° C, and in the summer, the outlet air temperature is 14 ° C or above. The dehumidification amount of the conventional air conditioner is directly related to the outlet air temperature, and the air is separated from the evaporator fin. The area is the lowest temperature region during the entire cooling process, and the water vapor saturation concentration in this area determines the moisture content of the air after dehumidification. The invention is different because the air outlet is not the area where the air has the lowest temperature during the entire cooling process, but is located in the demisting chamber, and the moisture content of the air after dehumidification depends on the defogging. The saturated concentration of water vapor in the chamber.

The time and path of the heat exchange between the air and the evaporator in the conventional air conditioner is very short. The surface temperature of the evaporator is very different from the temperature of the air after cooling. The temperature difference is generally around 10 °C when the air temperature is above 30 °C. Moreover, the higher the inlet air temperature, the greater the temperature difference. The invention makes the heat exchange path of the air and the heat sink much longer, the heat exchange temperature difference can be about 2 °C, and the inlet air temperature is high and almost unaffected. That is to say, when the two are at the same evaporator temperature, the condensation temperature of the dehumidification zone of the present invention is about 8 ° C lower, and the respective water vapor saturation concentrations are calculated according to the temperatures of the two, so that the air at the outlet air is 14 ° C. As an example of the water content, the conventional air conditioner can only reach 10 _g / m ₃ , while the present invention can reach 6.4 g / m ₃ and the dehumidification amount is increased by 36%.

It is worth noting that the present invention does not lower the evaporation temperature by sacrificing the energy efficiency of the refrigerator to exchange for a lower condensation temperature, but increases the heat exchange efficiency based on the existing evaporation temperature to reduce the dew point of the air, plus The water mist barrier mesh in the mist chamber can block most of the dewdrops flowing through the air, and the dew attached to the heat sink of the conventional air conditioner and the mist suspended between the sheets are easily taken out by the fan. The water treatment capacity of the present invention and the conventional air conditioner can be described as: the former "catch more, run less", while the latter "catch less, run more".

The dehumidification capacity of the invention is obviously improved in the environment of high temperature and high humidity, mainly reflected in the high-efficiency heat exchange, the air flowing through obtains a lower condensation temperature and precipitates more water, and the internal structure is combined to retain the precipitated water more. In combination with the above-mentioned equivalent evaporation temperature, the present invention can reduce the moisture content of the outlet air by about half compared with the existing air conditioner, and greatly improve the dehumidification effect.

The dehumidification method adopted by the conventional air conditioner at a low room temperature is to dehumidify by intermittently opening the refrigeration compressor, which causes a cold feeling when the compressor is running, and a feeling of sulking when the compressor is stopped. In the above case, the present invention can produce a dry air by continuously dehumidifying without substantially lowering the room temperature, and is very comfortable.

For example, in the wet and cold season below 20 °C and the relative humidity of air above 95%, the room temperature regulating valve can be reduced or even turned off. The air is dehumidified by the dehumidifying heat pipe and no longer cools down after the heat is returned. The relative humidity of the outlet can be about 35%. Through the heat exchange between the return air passage and the air of the intake passage, the final outlet air temperature can reach 18 ° C. The air at this temperature is expected to decrease only within 1 ° C of the room temperature after entering the indoor circulation, but the air humidity can be greatly reduced. In the conventional air conditioner, the outlet air temperature will be below 12 °C at the above temperature, in order to meet Dehumidification requires that the otherwise low temperature room will become colder and increase power consumption.

Conventional air conditioners have a "dehumidification mode" that can be used at low temperatures. In "dehumidification mode", the refrigerant compressors operate intermittently to prevent room temperature from decreasing and to prevent frost on the evaporator. At the same time, the running speed of the blower fan will decrease in the "dehumidification mode", sometimes it is very slow, in order to prevent the air from flowing too fast through the surface of the evaporator, and the water vapor is not enough to cause dew condensation due to insufficient heat exchange, which affects the dehumidification effect. It also prevents excessive winds from blowing water droplets attached to the surface of the evaporator. But the problem is: If the cycle of compressor opening and closing is too long, the fluctuation of indoor temperature and humidity will be too large, which will make people feel uncomfortable. If the cycle of compressor opening and closing is too short, it will reduce its life due to frequent starting, and Increasing power consumption, and slowing down the air blower will also affect the flow of indoor air, which will make people feel depressed.

The present invention completely improves the above situation. When the "dehumidification mode" is used in low temperature, the room temperature regulating valve controls the flow rate of the refrigerant to be little or even closed, and the cooling amount generated by the compressor operation is concentrated almost below the combined evaporator. The area of the dehumidification heat pipe is released, because the air flowing through the combined evaporator finally carries away a small amount of cold, and the actual consumption of the cold is mainly the latent heat of the water vapor condensation phase change, and in general, the latent heat energy consumption accounts for the total amount of refrigeration. The proportion of the compressor is not large. Even if the compressor is suspended, the cooling capacity stored in the combined evaporator can be maintained for a long time. Therefore, the intermittent cycle of the compressor can be greatly extended, and the compressor can be operated under the condition of fast cooling and slow cooling. The proportion of time is reduced. During the stop of the compressor, the blower fan can keep the normal air supply volume. As long as the temperature under the combined evaporator is still low, the dehumidification function can be maintained, as between the evaporator and the compressor. Connect the constant pressure valve in series, or use the inverter compressor or digital scroll compressor to adjust the refrigerant flow and make the compressor low. The continuous operation of the load continuously produces the air of the set temperature and humidity, and maintains the proper temperature, humidity and fluidity of the indoor air, and is very energy-saving.

The invention can exchange about 90% of the sensible heat by the combined evaporator at the time of low temperature dehumidification, and the outlet air temperature is close to the inlet air temperature, that is, the energy consumption for the air cooling part during dehumidification is about 10% of that of the conventional air conditioner, so Compared with the conventional air conditioner, the load of the compressor is much less when dehumidifying, and the energy saving effect is very obvious whether it is continuous work or intermittent work.

The invention controls the refrigeration compressor or the throttle valve to control the cooling capacity of the dehumidification heat pipe, can adjust the water content of the air outlet, and adjusts the flow rate of the room temperature regulating valve to increase or decrease the cooling capacity of the heat pipe of the air outlet, which can be adjusted The cooling range of the wind.

If the dehumidification requirement range allows, the evaporation temperature of the refrigerant inside the dehumidification heat pipe can be relatively fixed. The flow valve can use a capillary tube.

The heat-conducting medium circulating in the heat-dissipating heat-dissipating tube and the heat-dissipating tube of the air outlet may be a circulating refrigerant working directly provided by the refrigeration compressor, or a circulating refrigerant liquid made by the refrigeration system, and the effect is similar, through the multi-pipe branch The cold water is circulated separately from the multiple sets of combined evaporators and can be applied to central air conditioning projects.

The air outlet heat pipe and the dehumidifying heat pipe of the combined evaporator may belong to the same heat exchange circulation circuit, or a three-way valve may be respectively arranged at the inlet and outlet ends of the air outlet heat pipe to connect the peripheral pipe, and the air outlet heat pipe and the dehumidification heat pipe can be made. They are each independently assigned to different heat exchange loops. When the indoor heating air is needed and dehumidified at the same time, the air outlet heat pipe can cooperate with another heat exchange circulation circuit to realize the function of heating the dehumidified air.

Application test case 2:

The water-cooled central air conditioning system applying the technology of the invention comprises a chiller, a cold water circulation conveying system and a plurality of sets of throttle valves arranged in the room, a combined evaporator, a blower fan, a defogging chamber, a water mist barrier net, a drain port, etc. Together form a dehumidification refrigeration central air conditioning system. Through the central air conditioning system configured above, the chiller can be used and the low-temperature cold water can be transported as a heat exchange medium through the cold water circulation conveying system, and the dehumidification and cooling of the air can be performed by the cold water in the dehumidifying heat pipe and the air outlet heat pipe, in a high temperature climate. It is used for dehumidification and cooling of air in large public places, factories or multi-family homes. In the wet and cold season, the room temperature regulating valve can be turned off as a separate dehumidifier. Open the room temperature regulating valve and close the bypass valve to make the dehumidification heat pipe and the air outlet heat pipe collude. Only by controlling the throttle valve to control the flow of cold water, the wind humidity and temperature can be controlled simultaneously under a certain range, which is simple to use. Convenient, such as controlling less flow of cold water, the air flows through the dehumidifying heat pipe to obtain only a small amount of cooling, the condensation temperature is not too low, and the water analysis is limited. Moreover, when the cold water flows through the heat transfer pipe of the air outlet, the temperature thereof has risen, and the air does not have a cooling effect, and the low flow cold water can only dehumidify the air a little. For example, when controlling the flow rate in cold water, the air flows through the dehumidification heat pipe to obtain more cooling capacity, and the condensation temperature is relatively low, which can achieve a large dehumidification amount, but the temperature of the cold water rises slightly when flowing through the heat pipe of the air outlet. The air obtained from the air has a limited amount of cooling, and the medium-flow cold water can dehumidify and cool the air. For example, when controlling the large flow rate of cold water, the air can flow through the dehumidification heat pipe to obtain more cooling capacity, and the condensation temperature is relatively low, which can achieve a large dehumidification amount. When the cold water flows through the heat pipe of the air outlet, the temperature can be basically maintained. The air can continue to be greatly cooled down, and the large flow of cold water can simultaneously dehumidify and cool the air. All in all, the cold water with cold water is first consumed by the latent heat required for dehumidification, and the remaining part of the cold is used to cool the air.
