Document Type and Number:
Japanese Patent JP6739292
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method of inspecting a heat pump system that can correctly recognize a refrigerant filling amount for a refrigerant circulation path.SOLUTION: A method of inspecting a heat pump system has: a status value detecting process of detecting, after letting a refrigerant sent out from compression means 5 flow to a first heat exchanger 8, a second expansion valve V2 and a third heat exchanger 10 in order in a cutoff state in which the refrigerant is not circulated via the first expansion valve V1 and a second heat exchanger 14, a status value of a refrigerant being circulated while performing an inspecting operation by switching the circulation state of the refrigerant so that the refrigerant returns to the compression means 5; and a refrigerant filling amount determination process of determining, based upon the status value detected in the status value detecting process, whether the filling amount of the refrigerant present in a refrigerant circulation path 3 is proper.SELECTED DRAWING: Figure 2
