Air conditioner with electromagnetic induction heating unit

摘要

An air conditioner includes a refrigerant circuit, an electromagnetic induction heating unit, and a control unit. The refrigerant circuit has a compressing mechanism with an adjustable operating capacity, a heat source side heat exchanger, an expansion mechanism, and a utilization side heat exchanger. The electromagnetic induction heating unit heats a refrigerant piping and/or a member that is in thermal contact with a refrigerant that flows through the refrigerant piping. The control unit sets the electromagnetic induction heating unit to a forced inhibit state if any one of a condition in which the electromagnetic induction heating unit has been manually set to operation inhibited; a condition in which an air conditioning load is small; and a condition in which an amount of circulating refrigerant is small is satisfied.

主权项

1. An air conditioner, comprising:
a refrigerant circuit including a compressing mechanism with an adjustable operating capacity, a heat source side heat exchanger, an expansion mechanism, and a utilization side heat exchanger; an electromagnetic induction heating unit arranged and configured to heat a refrigerant piping and/or a member that is in thermal contact with a refrigerant that flows through the refrigerant piping; and a control unit configured to set the electromagnetic induction heating unit to a forced inhibit state if any one of
a condition in which an air conditioning load is small is satisfied, anda condition in which an amount of circulating refrigerant is small is satisfied, the condition in which the amount of circulating refrigerant is small being satisfied when a pressure on a low pressure side is less than or equal to a pressure and a limit is applied to the operating capacity of the compressing mechanism.
