Korean Patent Application No. 1986-0010374 (filed December 4, 1986) introduces a "power unit for converting heat into power."

The power unit for converting heat into power is a transferable power unit for converting heat into electric power, comprising: a machine frame including a vertical plate, mounted on the vertical plate, and having one end thereof on one side of the vertical plate; A horizontal boiler mounted on the vertical plate above the boiler and having one end on one side of the vertical plate, mounted on one side of the vertical plate and extending horizontally on opposite sides of the vertical plate. A device for circulating a refrigerant in the boiler through a stage of a Rankine cycle comprising a double displacement expander of a rotary constrained vane having an output shaft and expanding pressurized refrigerant vapor from the boiler to the condenser through the expander. Connecting the end of the boiler and the condenser to the inflator and providing the condenser The liquid refrigerant condensed from the boiler to the boiler is recovered by gravity transfer, and a refrigerant circuit for condensing refrigerant vapor into liquid in the condenser, and an electric power generator mounted on the frame adjacent to the opposite side of the vertical plate. A high temperature fluid heat exchange circuit device for connecting said boiler to a heat source comprising a heat exchanger associated with said boiler, a cold and hot fluid heat exchange circuit device for connecting said condenser to a cold source comprising a heat exchanger associated with said condenser, said heat exchange circuit and said A fluid circulation pump device mounted on the vertical plate connected to the one side of the vertical plate in a drive shaft extending horizontally on the opposite side of the vertical plate, controlling the flow rate of refrigerant steam from the boiler to expansion to control the power; The parallel drive shaft of the generator and the fluid circulation pump device at a harmonic speed And a device for harmonizing the flow rate of the fluid through a heat exchange circuit comprising a belt drive on the opposite side of the vertical plate connected to the output shaft of the expander for driving.

However, the power unit for converting the heat into power has a problem of environmental pollution due to the use of fossil fuel because the boiler is used as an external heat source by using only one heat medium (refrigerant) to heat exchange in the boiler.

Accordingly, an object of the present invention is that the first heat medium of the outer circulation circle absorbs heat from the outside through the heat absorber while heat-exchanging while flowing in a direction opposite to the second heat medium of the inner circulation circle, thereby absorbing heat. Power can be obtained in the process of expanding the heat medium in the expander, so the use of fossil fuels (petroleum, coal, nuclear power, etc.) is not required, so there is no pollution, and there is more power energy output than the power used. Since there is no explosion process as in the present invention, there is less noise, and consequently, it is to provide a heat absorbing power generator that can be applied as an air conditioner or a refrigerator or a water-cooled cooler without an outdoor unit.

Preferred embodiments of the present invention for achieving the above object will be described in detail with reference to the drawings.

Referring to FIG. 1, a heat absorption power generator according to a first embodiment of the present invention includes an external circulation circle 10 including an expander 11 for generating power, and an inside of the external circulation circle 10. An inner fluid circle 20 disposed in a direction opposite to the first heat medium (not shown) of the outer circulation circle 20, and an outer fluid as a first heat medium of the outer circulation circle 10. The heat absorber (H3) for transmitting the heat of the first heat exchanger (H1) and the second heat exchanger (H2) in the first heating medium and the inner circulation circle 20 of the first circulation medium (10), respectively 2 The heat medium exchanges heat.

The first heating medium of the outer circulation circle 10 should be selected to have a higher temperature difference of boiling point than the second heating medium of the inner circulation circle 20, and the boiling point must be lower than the temperature of the outer fluid supplied to the heat absorber (H3). . For example, when using a 1st heat medium as isobutane (boiling point -12 degreeC), it is preferable to select R22 (boiling point -40.8 degreeC) etc. which are much lower in boiling point than this.

The external circulation circle 10 is a liquid first heat medium is introduced into the heat absorber (H3), the first heat medium absorbs the heat of the external fluid in the heat absorber (H3) is phase-converted to gas, gaseous The first heat medium becomes superheated steam through heat exchange with the second heat medium of the internal circulation circle 20 in the first heat exchanger, and the second heat medium in the superheated steam state is supplied to the expander 11 through the throttle valve 15. In order to generate power by operating an output shaft (not shown) of the expander 11 while adiabatic expansion in the expander 11, the first heat medium in the gaseous state in the second heat exchanger (H2) is the internal circulation circle 20 By heat-exchanging with the 2nd heat medium of), it is phase-converted to a liquid phase, and the liquid 1st heat medium is supplied to the heat absorber H3 by the liquid pump 13.

When the outer circulation circle 10 through which the first heating medium circulates as described above is applied to the power generation system, the expander 11 may correspond to a turbine, and when the outer circulation circle 10 is applied to another system, the expander ( 11) may be a rotary expander, a double displacement expander, a reciprocating expander.

The inner circulation circle 20 sends the second heat medium in the superheated vapor state compressed at high temperature and high pressure by the compressor 21 to the first heat exchanger H1, and thus, the external circulation circle 10 in the first heat exchanger H1. By heat-exchanging with the first heat medium of), heat is supplied to the first heat medium of the outer circulation circle 10, and the second heat medium condensed thereby is adiabaticly expanded by passing through the expansion valve 23, and the second low temperature is applied. The heat medium is heat-exchanged with the first heat medium of the outer circulation circle 10 in the second heat exchanger H2, and absorbs heat from the first heat medium of the outer circulation circle 10, thereby compressing the second heat medium in the vapor state by the compressor 21. To supply.

This internal circulation circle 20 is like a heat pump system, and the second heat exchanger H2 is used as the condenser.

The heat absorber (H3) may use air or water as the external fluid, so that the external fluid does not flow below the boiling point of the first heat medium.

In the heat absorption type power generating apparatus according to the present invention configured as described above, since power is generated in the expander 11 through the first heat medium of the outer circulation circle 10, it will be described based on the circulation of the first heat medium. 1 The heat medium absorbs the heat of the external fluid in the heat absorber (H3) and is converted into gas. For example, when the first heat medium is isobutane, since the boiling point is -12 ° C, when the temperature of the first heat medium flowing into the heat exchanger H3 is -15 ° C, the external fluid of 20 ° C is a heat absorber (H3). In the case where heat is exchanged with the first heat medium in a counterflow manner, the first heat medium may be discharged from the heat absorber H3 in a gas state of at least 15 ° C. or more.

Thereafter, the first heat medium becomes superheated steam through heat exchange with the second heat medium of the internal circulation circle 20 in the first heat exchanger H1. That is, in the process of heat-exchanging the second heat medium at 80 ° C. by the compressor 21 at the first heat exchanger H1, the first heat medium becomes overheated steam at 70 ° C. or higher, and this flows into the expander 11. Power is generated by operating the output shaft of the expander 11.

The heat-absorbing power generator according to the present invention operated as described above has a power factor (COP) of 5, the power used in this system (motor of compressor 21, pump for external fluid transfer pump or fan of motor ( 31), up to 4.4 times the output energy can be obtained compared to the power used in the motor of the liquid pump 13, and the power can be obtained by absorbing heat from external water or air, so that fossil fuel (petroleum, coal) can be obtained. No nuclear power is required.

Referring to Figure 2, the heat absorption power generator according to the second embodiment of the present invention is a steam transfer pump mounted in the line between the heat absorber (H3) and the first heat exchanger (H1) in the outer circulation circle (10) It is the same as the heat absorption type power generating apparatus according to the first embodiment except that it further includes (15).

The steam transfer pump 15 must reliably divide the heat absorber (H3) into the evaporator and the first heat exchanger (H1) into the superheater to prevent the liquid first heat medium from flowing into the first heat exchanger (H1). Used when

As described above, the absorption type power generator according to the present invention can obtain power by absorbing heat from external water or air, so that fossil fuels (petroleum, coal, nuclear power, etc.) are not required, and thus no pollution occurs. In addition, there is a lot of power energy output compared to the power used, there is no explosion process, as in the internal combustion engine, there is little noise, and there is an effect that can be applied to an air conditioner or a refrigerator or a water-cooled cooler without an outdoor unit.
