Title:
冷凍装置
Document Type and Number:
Japanese Patent JP5819006
Kind Code:
B2
Abstract:
There are provided a high-temperature side circulation circuit A including a high-temperature side compressor 1, a high-temperature side condenser 2, a high-temperature side expansion valve 3, and a high-temperature side evaporator 4 sequentially connected by piping to circulate a refrigerant therethrough, a low-temperature side circulation circuit B including a low-temperature side compressor 5, a low-temperature side condenser 7, a low-temperature side flow control valve 10, and a low-temperature side evaporator 12 sequentially connected by piping to circulate a refrigerant therethrough, a cascade capacitor 8 formed of the high-temperature side evaporator 4 and the low-temperature side condenser 7 to exchange heat between the refrigerant flowing through the high-temperature side evaporator 4 and the refrigerant flowing through the low-temperature side condenser 7, and a plurality of expansion tanks 18 connected to a pipe between the low-temperature side condenser 7 and the low-temperature side compressor 5 via a low-temperature side second solenoid valve 17. The high-temperature side compressor 1, the high-temperature side condenser 2, the high-temperature side expansion valve 3, the high-temperature side evaporator 4, the low-temperature side compressor 5, and the low-temperature side condenser 7 are mounted in an outdoor unit 14, and the plurality of expansion tanks 18 are mounted in an expansion tank unit housing 31.
