摘要：
Provided is a refrigeration apparatus that minimizes increase in the size of the heat exchanger for injection while maintaining the function of reducing the discharge temperature of the compressor. An air conditioning apparatus (10) that uses R32 for the refrigerant, is provided with a compressor (20), an indoor heat exchanger (50), an outdoor expansion valve (41), an outdoor heat exchanger (30), a branch flow pipe (62), and an electric injection valve (63) and a heat exchanger (64) as well as a high-pressure receiver (80) and the like. The heat exchanger (64) exchanges heat between refrigerant that flows in the main refrigerant passage (11a) and refrigerant that passes through the electric valve (63) of the branch flow pipe (62). A first injection channel (65) guides refrigerant that flows through the branch flow pipe (62) and exits the heat exchanger (64) of the compressor (20). A second injection channel (82) guides the gas component of refrigerant of the high-pressure receiver (80) to the compressor (20).
摘要（中）：
本发明提供一种制冷装置，该制冷装置在维持降低压缩机排出温度的功能的同时使注入用热交换器的大型化最小化。 在制冷剂中使用R32的空调装置10具备压缩机20，室内热交换器50，室外膨胀阀41，室外热交换器30， （62），电动喷射阀（63）和热交换器（64）以及高压接收器（80）等。 热交换器64在主制冷剂通路11a内流动的制冷剂与通过分支流路管62的电动阀63的制冷剂之间进行热交换。 第一注入通道（65）引导流过分支流管（62）并离开压缩机（20）的热交换器（64）的制冷剂。 第二注入通道（82）将高压接收器（80）的制冷剂的气体成分引导至压缩机（20）。
