[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a heat dissipation utilization system for a refrigerator in which heat emitted from the refrigerator is used for other heat engines such as an absorption refrigerator and a boiler.

[0002]

[Prior Art]

 The structure of a general refrigerator is shown in FIG. In the figure, a refrigerant such as CFC gas circulates in the pipeline 1 in the direction of the arrow in the figure. The refrigerant expands and gasifies in the evaporator 2 to remove heat from the surroundings and cool the inside of the freezing compartment (not shown). The gasified refrigerant is pressurized by the compressor 3 and becomes a liquid refrigerant again and is sent to the condenser 4. Then, the condenser 4 dissipates heat and becomes a low-temperature liquid refrigerant, which is sent again to the evaporator 2 via the expansion valve 5.

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing a heat dissipation utilization system of a refrigerator according to an embodiment of the present invention. In the figure, the evaporator 2, the compressor 3, the heat exchanger 10, and the expansion valve 5 are connected by a pipe line 1 to form a general refrigerator system. That is, a refrigerant such as CFC gas circulates in the pipe line 1 in the direction of the arrow shown in the figure, and this refrigerant has a gasification and endothermic action in the evaporator 2 and is pressurized and liquefied in the compressor 3 to be a heat exchanger. The temperature is lowered at 10 and sent again to the evaporator 2.

Here, as shown in FIG. 2, the heat exchanger 10 includes a main body 13 including an inner cylinder 11 and an outer cylinder 12 each having a bottom, and heat is generated in a gap between the inner cylinder 11 and the outer cylinder 12. Along with forming the exchange chamber 14, a refrigerant pipe 15 is spirally arranged in the heat exchange chamber 14. The inlet 14a and the outlet 14b of the heat exchange chamber 14 and the inlet 15a and the outlet 15b of the refrigerant pipe 15 are provided at one end and the other end of the main body 13, and the inlets and outlets 15a and 15b of the refrigerant pipe 15 are provided in the pipeline 1. In addition to being connected, the inlets / outlets 14a and 14b of the heat exchange chamber 14 are connected to another heat engine described later. In this heat exchanger 10, since the heat exchange chamber 14 is formed between the inner cylinder 11 and the outer cylinder 12, the volume of the heat exchange chamber 14 is minimized and effective heat exchange is possible. Is becoming

FIG. 3 is a block diagram showing an embodiment in which the system of the present invention is connected to an absorption refrigerator. As is well known, the absorption refrigerator 20 sends the refrigerant evaporated in the evaporator 21 to the absorber 22, and dissolves the gasified refrigerant in an absorbing solution such as lithium bromide stored in the absorber 22. The absorbing solution in which the refrigerant is dissolved is sent to the generator 24 by the pump 23, where it is heated by the hot water passing through the heating pipe line 25, and the refrigerant evaporates and separates. The evaporated refrigerant is condensed in the condenser 26 and is selected again in the evaporator 21. The absorbing solution obtained by evaporating the refrigerant and concentrating it is returned to the absorber 22 via the heat exchanger 27.

In this embodiment, the heating pipeline 25 provided in the generator 24 of the absorption refrigerator 20 is connected to the inlets / outlets 14 a and 14 b of the heat exchange chamber 14 of the heat exchanger 10 by the pipe 28. I am doing it. In the pipe 28, a heat exchange medium (water in this embodiment) is circulated by a pump 29, and the heat taken from the refrigerant in the heat exchange chamber 14 is used for heating the absorbing solution in the generator 24.

In this embodiment, the water supply tank 31 of the boiler 30 is connected to the inlets / outlets 14a and 14b of the heat exchange chamber 14 of the heat exchanger 10 by the pipe 32. Then, the water in the water supply tank 31 is sent to the heat exchange chamber 14 by the pump 33, and the water whose temperature has been raised by heat exchange with the refrigerant is returned to the water supply tank again to realize the heating efficiency of the boiler 30. There is.

Note that the present invention is not limited to the above-described embodiment, and for example, heat absorbed from the refrigerant by the heat exchanger is supplied to various heat engines other than the absorption chiller and the boiler. The system can be configured.
