Title:
REGENERATIVE AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2016/103711
Kind Code:
A1
Abstract:
In order to avoid reduction in compressor efficiency during low loads in a regenerative air conditioner, the regenerative air conditioner comprises: a refrigerant circuit (11) performing a refrigeration cycle and having a compressor (22), an outdoor heat exchanger (23), and an indoor heat exchanger (72); and a heat-storage unit (60) having a heat-storage medium and causing said heat-storage medium to exchange heat with refrigerant in the refrigerant circuit (11). The regenerative air conditioner can execute: a simple refrigeration operation in which refrigerant is condensed by the outdoor heat exchanger (23) and refrigerant is evaporated by the indoor heat exchanger (72), in the refrigerant circuit (11); and a refrigeration-and-cold storage operation in which refrigerant is condensed by the outdoor heat exchanger (23) and refrigerant is evaporated by the indoor heat exchanger (72), in the refrigerant circuit (11), and a heat-storage medium in a heat-storage unit (60) is cooled by the refrigerant. The regenerative air conditioner comprises an operation control unit (100) that, if the rotation speed of the compressor (22) drops to a prescribed lower reference value during simple refrigeration operation, switches operation of the regenerative air conditioner from the simple refrigeration operation to the refrigeration-and-cold storage operation and causes the rotation speed of the compressor (22) to increase.
