Title: HEAT CYCLE SYSTEM
Abstract:
A heat cycle system (1) that uses a working medium containing a hydrofluoroolefin (HFO) having a double bond in the molecular structure, wherein the heat cycle system has a compressor (10), a high pressure-side heat exchanger (12), a low pressure-side heat exchanger (14), and an expansion mechanism (13), and comprises an acid detection means (40) that is provided in delivery piping (21) connecting the compressor (10) and the high pressure-side heat exchanger (12) and that detects acid generated by decomposition of the working medium in the heat cycle.
