A refrigerating apparatus including a refrigerant circuit (10) in which such a refrigerating cycle that the pressure of a refrigerant discharged from a compressor (22) is increased to a critical value or higher. When the heating operation is performed in a first indoor heat exchanger (33a) and a second indoor heat exchanger (33b) is stopped to operate, an indoor expansion valve (34b) corresponding to the indoor heat exchanger (33b) being stopped to operate is fully closed.
Description
[0001] The patent application for this invention is a divisional application of the invention patent application with the international application number PCT / JP2007 / 054405, the international application date is March 7, 2007, and the application number entering the Chinese national phase is 200780008199.0, and the name is "refrigeration device". technical field [0001] The present invention relates to a refrigerating device capable of separate heating operations of a plurality of use-side heat exchangers, and particularly relates to countermeasures against refrigerant liquefaction and accumulation in the use-side heat exchangers in a stopped state. Background technique [0002] A refrigeration device that circulates a refrigerant to perform a refrigeration cycle is widely used in air conditioners and the like. As such an air conditioner, there is a so-called multi-type air conditioner in which a plurality of indoor units are connected to the outdoor unit in parallel with th...
