REFRIGERATION DEVICE
Document Type and Number:
Japanese Patent JP2016200361
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a refrigeration device suitable for a power-saving cooling operation.SOLUTION: An air conditioning system 1 includes: a compressor 11 and a second outdoor heat exchanger 21 installed outdoors; an indoor heat exchanger 31 and an indoor electric valve 32 installed indoors and configuring a refrigerant circuit with the compressor 11 and the second outdoor heat exchanger 21; a liquid refrigerant temperature sensor 56 for detecting a temperature of a refrigerant flowing into the indoor electric valve 32; and a controller 50. The controller 50 switches an ordinary cooling operation for driving the compressor 11 to forcibly circulating the refrigerant and a power-saving cooling operation for stopping the compressor 11 to circulate the refrigerant by utilizing an installation height difference H1 between the second outdoor heat exchanger 21 and the indoor heat exchanger 31, according to a situation. The controller 50 performs a power-saving cooling start determination processing for determining whether or not to start the power-saving cooling operation on the basis of a detection value Tof the liquid refrigerant temperature sensor 56.SELECTED DRAWING: Figure 1
