The cold air 'condenses to generate heat and is blown to the outside (or where hot air is required) 'The low-temperature low-pressure liquid refrigerant condensed and discharged in the second heat exchanger 30 described above flows into the dryer through the second check valve 2〇40 26 ° The moisture contained in the inflowing low-temperature low-pressure liquid refrigerant is removed from the dryer 26, and the low-temperature low-pressure liquid refrigerant having been removed from the dry balancer 26 is expanded into a low-temperature low pressure in the second expansion chamber 42. The gaseous refrigerant is passed through the fourth electromagnetic wide 36 into the third heat exchange used as an evaporator 19 200844376 in the converter 39. The low-temperature low-pressure gaseous refrigerant flowing into the third heat exchanger 39 is driven by the second blower 38 interlocked with the drive motor 38A to blow the air into the third heat exchanger 39 to cool the heat exchange. The cold air is discharged into the indoor room to control the temperature in the room, so that the proper indoor temperature can be controlled. At this time, the temperature of the cold air which is exchanged in the third heat exchanger 39 to the cold air and supplied to the room (not shown) is displayed on the supply temperature display unit 58 of the control unit 5A. On the other hand, the heat exchange of 10 gaseous refrigerants (half liquid semi-air refrigerant) in the third heat exchanger 39 through the third solenoid valve 34 and the b port and d port flow in the above four-way valve 12 In the intake liquid separator 32, a warm gaseous refrigerant flowing into the gas-liquid separator 32 is separated, and the liquid refrigerant contained in the low-temperature low-pressure gaseous refrigerant is separated in the gas-liquid separator 32, and the pure liquid is contained in the gas-liquid separator 32. The gaseous refrigerant is discharged to the compressor 1〇, and is compressed into a high-temperature high-pressure gaseous refrigerant as the pressure of the compressor 15 is compressed, and then supplied to the above through the a port and the c port of the four-way valve 12 as described above. In the second heat exchanger 30, the operation as described above is performed. In the above description, although an industrial duplex waste heat recovery device has been exemplified, the present invention is also applicable to a waste heat recovery device for agricultural and aquatic products. In the above description, the specific embodiments have been illustrated and described, but the present invention is not limited thereto, and those having ordinary knowledge in the art may carry out various kinds without departing from the scope of the present invention. Various deformations and designs. In summary, the industrial double waste heat recovery device according to the present invention, 20 200844376 has the waste heat recovered, and uses the refrigerant circulation to reduce the high temperature to low in the summer, and to supply the indoors in the summer, while the low temperature rises in the winter. A pound of people Ah Wen is supplied indoors, so that the cost of warm air conditioning can be reduced to (10), the industry, private, and water argon argon discharge to prevent the earth's greenhouse.
