Title:
REFRIGERATION CYCLE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/008053
Kind Code:
A1
Abstract:
A refrigeration cycle system, provided with: a dual refrigeration cycle having a high temperature-side circuit, in which a first compressor, a first heat exchanger, a condenser, a first expansion valve, and a cascade heat exchanger are connected by refrigerant piping, and a low temperature-side circuit in which a second compressor, a second heat exchanger, the cascade heat exchanger, a second expansion valve, and an evaporator are connected by refrigerant piping, the low temperature-side circuit exchanging heat with the high temperature-side circuit in the cascade heat exchanger; and a waste heat recovery circuit in which the first heat exchanger and the second heat exchanger are connected by piping, the waste heat recovery circuit channeling a heat medium. The waste heat recovery circuit has a first channel for channeling the heat medium from the first heat exchanger to the second heat exchanger, a second channel for channeling the heat medium from the second heat exchanger to the first heat exchanger, and a channel-switching device for switching between the first channel and the second channel.
