Document Type and Number:
WIPO Patent Application WO/2016/117126
Kind Code:
A1
Abstract:
The present invention is provided with a control means 100 for performing a liquid equalization control for correcting an unbalance when there is an unbalance in the amounts of liquid refrigerant between a plurality of accumulators 4 (104). The control means 100 has a first liquid equalization control means 100a for performing a liquid equalization control by controlling the output of a blower 6 (106), and a second liquid equalization means 100b for performing a liquid equalization control by controlling a frequency of a compressor 1 (101). The second liquid equalization control means 100b serves to determine an increment/decrement of the frequency of the compressor 1 (101) such that the total refrigerant circulation amount is not less than a prescribed amount, and the control means 100 performs the liquid equalization control by selecting the first liquid equalization control means 100a when a calculated value from a heat exchange amount calculating means 39 (139) is within a prescribed allowable range, and by selecting the second liquid equalization control means 100b when the calculated value is outside the allowable range.
