The controller (60) controls the second expansion mechanism (33) and the pressure adjustment mechanism (34) under operating conditions in which the heat source-side heat exchanger (13) functions as a radiator, the first use-side heat exchanger (21) and the second use-side heat exchanger (31) functions as evaporators, and the first use-side heat exchanger (21) may frost. Therefore, the second utilization-side heat exchanger (31) is not frosted.
在热源侧热交换器(13)作为散热器发挥作用、第一利用侧热交换器(21)及所述第二利用侧热交换器(31)作为蒸发器发挥作用、并且第一利用侧热交换器(21)可能结霜的运转条件下,控制器(60)控制第二膨胀机构(33)及压力调节机构(34),以使第二利用侧热交换器(31)不结霜。
