Title:
REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/139783
Kind Code:
A1
Abstract:
This refrigeration cycle device comprises: a heat source circuit that is equipped with a compressor, a heat source side heat exchanger, a decompression device, and an inter-heat medium heat exchanger and circulates a refrigerant therethrough; a load circuit that is equipped with an inter-heat medium heat exchanger, a load-side heat exchanger, and a pump and circulates a heat medium therethrough; and a control device. The inter-heat medium heat exchanger exchanges heat between the refrigerant and the heat medium. If the operating time after the compressor thermo-on is shorter than reference time, the control device sets the upper limit frequency of the compressor to be lower than the currently set upper limit frequency.
