Document Type and Number:
WIPO Patent Application WO/2014/122735
Kind Code:
A1
Abstract:
Provided is a refrigeration device for preventing decrease in performance due to a start/stop operation. In an air conditioning device (1), when an outdoor unit (2) is in a low capability state that is nearly a resting state, the rotational speed of a compressor (21) is assumed to be equal to or less than a rotation-controllable range of an inverter, an indoor unit that, of a plurality of indoor units (4a, 4b, 4c) is in an indoor thermo-off state, is therefore forcibly switched to an indoor thermo-on state, and the rotational speed of the compressor (21) is returned to the rotation-controllable range of the inverter, whereby the outdoor unit (2) can be inhibited from going into the resting state or the low capability state.
