Title:
REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/140879
Kind Code:
A1
Abstract:
The objective is to provide a safe, high-performance refrigeration cycle device with which it is possible to avoid a condition wherein the refrigerant causes a chain reaction, even when a refrigerant that generates a disproportionation reaction is used in the refrigeration cycle device. This refrigeration cycle device is equipped with: a main circuit wherein a compressor, a first heat exchanger, an expansion valve, and a second heat exchanger are sequentially connected, and in which a non-azeotropic mixed refrigerant (which includes at least a first refrigerant and a second refrigerant characterized by having a higher boiling point than the first refrigerant under the same pressure) operates as a standard composition refrigerant; and a composition separation circuit connected to the main circuit. The first refrigerant has the property of producing a disproportionation reaction, and the composition separation circuit is configured such that when operating in a separation/storage mode wherein the composition of the standard composition refrigerant is separated, a mixed refrigerant for which the composition ratio of the first refrigerant is higher than the standard composition refrigerant is separated from the main circuit, and is stored.
