ABSTRACT:
A refrigerant flow rate measuring apparatus has a means for detecting the opening degree A of an expansion valve of a refrigeration cycle, a pressure detecting means for detecting the refrigerant pressure Pi at upstream side of the expansion valve, a pressure detecting means for detecting the refrigerant pressure Po at downstream side of the expansion valve, a refrigerant density detecting means for detecting the density .gamma.i of the refrigerant at the inlet side of the expansion valve, a converting means for directly or indirectly converting the values detected by the detecting means into electric signals, and a calculating means for calculating the flow rate of the refrigerant in accordance with the following formula, from the electric signals. ##EQU1##
