Title:
COOLING SYSTEM, AIR RESIDUAL QUANTITY MEASURING DEVICE, COOLING DEVICE AND REFRIGERANT FILLING METHOD
Document Type and Number:
Japanese Patent JP2017180858
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a cooling system, an air residual quantity measuring device, a cooling device and a refrigerant filling method enabling time for filling a refrigerant to be shortened.SOLUTION: In a work for filling a refrigerant in a cooling device 300, the refrigerant is filled in the cooling device 300 by using a filling device, and then, the cooling device 300 is connected to an air residual quantity measuring device 400. The pressure in the cooling device 300 is raised by the air residual quantity measuring device 400, and based on the pressure in the cooling device 300 and movement amount of the refrigerant at this time, air residual quantity in the cooling device 300 is calculated. Depending on the calculated air residual quantity, the cooling device 300 is replenished with the refrigerant. Due to this configuration, it is unnecessary to perform an air vent operation during filling of the refrigerant, so as to enable time for filling the refrigerant to be shortened.SELECTED DRAWING: Figure 6
