Title:
HEAT PUMP CYCLE APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/276626
Kind Code:
A1
Abstract:
This heat pump cycle apparatus comprises: a defrosting operation execution unit (S6, S7) for executing a defrosting operation, in which a heat-absorbing unit (35) is defrosted, when it is assessed by a frosting assessment unit (S1) that frosting has occurred on the heat-absorbing unit (35); and a defrosting operation prohibition unit (S4, S5) for prohibiting executing of the defrosting operation by the defrosting operation execution unit (S6, S7). During execution of the defrosting operation, the defrosting operation execution unit (S6, S7) defrosts the heat-absorbing unit (35) by using a heat medium heated by a heat-emitting unit (81) as a heat source. The defrosting operation prohibition unit (S4, S5) prohibits subsequent execution of the defrosting operation until a defrosting elapsed time (Tm2), which is the elapsed time from when the previous instance of the defrosting operation ended, is equal to or greater than a defrosting standby time (Tmi2).
