Title:
REFRIGERATION CYCLE DEVICE
Document Type and Number:
Japanese Patent JP2017053566
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To determine a refrigerant amount with high accuracy.SOLUTION: A refrigeration cycle device comprises: a compressor; a condenser; an evaporator; a decompressor; a supercooling device which performs supercooling of a refrigerant condensed by the condenser; a supercooling degree calculation section 114 which estimates a reasonable supercooling degree of the refrigerant at an exit of the supercooling device on the basis of an amount of the refrigerant circulated from the compressor to the condenser and the supercooling device and calculates a determination threshold to determine the amount of the refrigerant on the basis of the estimated reasonable supercooling degree; and a refrigerant amount determination section 115 which determines the refrigerant amount by comparing a measured supercooling degree with the determination threshold.SELECTED DRAWING: Figure 2
