Title:
REFRIGERATION CYCLE APPARATUS
Document Type and Number:
WIPO Patent Application WO/2015/140870
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a safe and high-performance refrigeration cycle apparatus whereby, even when a refrigerant that can cause a disproportionation reaction is used in the refrigeration cycle apparatus, it becomes possible to avoid the refrigerant being exposed to a condition in which the reaction can occur in succession. A refrigeration cycle apparatus, in which a non-azeotropic refrigerant mixture is used as a working refrigerant, wherein the non-azeotropic refrigerant mixture comprises at least a first refrigerant and a second refrigerant having such a property that the boiling point of the second refrigerant can become higher than that of the first refrigerant under the same pressure. The refrigeration cycle apparatus is equipped with at least a main passage, wherein the main passage is equipped with a compressor, a first heat exchanger, a first expansion valve and a second heat exchanger which are connected in this order. The refrigeration cycle apparatus is so configured that the first refrigerant has a property of causing a disproportionation reaction, and the compositional ratio of the first refrigerant present in the compressor is smaller than the compositional ratio of the first refrigerant that flows through the main passage.
