Title:
REFRIGERATION DEVICE AND REFRIGERANT AMOUNT ADJUSTMENT METHOD OF REFRIGERATION DEVICE
Document Type and Number:
Japanese Patent JP2015049024
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a refrigeration device capable of smoothing a refrigerant amount adjustment work in installing a refrigerator and a cooling apparatus.SOLUTION: A refrigeration device R is composed of a refrigerator 3 having a compressor 11 and a gas cooler 46, and a showcase 5 having a main expansion valve 62 and an evaporator 63, and the refrigerator and the showcase are connected by a high-pressure pipe 7 and a low-pressure pipe 9 to constitute a refrigerant circuit 1. A refrigerant compressed by the compressor and passing through the gas cooler is sent to the main expansion valve by the high-pressure pipe, the refrigerant discharged from the evaporator is returned to the compressor by the low-pressure pipe, and the high pressure-side has a supercritical pressure. Control means is disposed to control the compressor and the main expansion valve, and the control means has a function for determining a refrigerant amount in the refrigerant circuit.
