Title:
CONTROL DEVICE FOR AIR CONDITIONING DEVICE, OUTDOOR UNIT, RELAY UNIT, HEAT SOURCE UNIT, AND AIR CONDITIONING DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/017030
Kind Code:
A1
Abstract:
An air conditioning device (1) comprises: a compressor (11); a first heat exchanger (13); a second heat exchanger (22) that exchanges heat between a first heat medium and a second heat medium; a plurality of flow rate adjusting valves (33, 43, 53); and a pump (23) that circulates the second heat medium between a plurality of third heat exchangers (31, 41, 51) and the second heat exchanger (22). In a heating mode, a control device (100): opens a flow rate adjusting valve corresponding to a heat exchanger, among the plurality of third heat exchangers (31, 41, 51), for which an air conditioning request has been generated; and closes a flow rate adjusting valve corresponding to a heat exchanger, among the plurality of third heat exchangers (31, 41, 51), for which an air conditioning request has not been generated. In a defrosting mode, when the temperature of the second heating medium is lower than a first determination temperature, the control device (100) opens at least one flow rate adjustment valve corresponding to a heat exchanger for which an air conditioning request has not been generated.
