制冷循环装置和具备该制冷循环装置的空气调节机
摘要：
本发明的制冷循环装置，设置有三通阀（切换装置）（42），该三通阀（42）在压缩机（6）的吸入管和四通阀（8）之间，能够切换使制冷剂从四通阀（8）直接流至压缩机（6）的吸入管的配管（25）和使制冷剂从四通阀（8）通过制冷剂加热用的辅助热交换器（蓄热箱（32）、蓄热热交换器（34）、蓄热材料（36））而流至压缩机（6）的吸入管的配管（38），在除霜运转时，控制三通阀（切换装置）（42），使流过室内热交换器（第一热交换器）（16）和室外热交换器（第二热交换器）（14）的制冷剂经由四通阀（8）流过辅助热交换器（蓄热箱（32）、蓄热热交换器（34）、蓄热材料（36）），引导至压缩机（6）的吸入管。
摘要（英）：

A three-way valve (switching device) (42) is provided between an intake tube of a compressor (6) and a four-way valve (8), making possible a switch between a tube (25) draining refrigerant directly from the four-way valve (8) into the intake tube of the compressor (6) and a tube (38) draining refrigerant from the four-way valve (8) into the intake tube of the compressor (6) through an alternate heat exchanger (heat storage tank (32), heat storage exchanger (34), heat storage material (36)) for refrigerant heating; and by controlling the three-way valve (switching device) (42) during defrosting operation, refrigerant flowing to an indoor heat exchanger (first heat exchanger) (16) and an outdoor heat exchanger (second heat exchanger) (14) flows to the alternate heat exchanger (heat storage tank (32), heat storage exchanger (34), heat storage material (36)) via the four-way valve (8), and is guided to the intake tube of the compressor (6).
