Air conditioning and anti poison and air conditioning control procedure (air conditioning control procedure)

摘要

The present invention enables appropriate cleaning of a heat exchanger of an air conditioner during a cleaning operation. This air conditioner is provided with: a refrigeration cycle having a compressor that compresses a refrigerant and an indoor heat exchanger; a control device that controls the refrigeration cycle so as to carry out a cleaning operation for cleaning the surface of the indoor heat exchanger; and an indoor fan, wherein the control device has functions (S130, S132, S134) for carrying out freezing control so as to cause the indoor heat exchanger to function as an evaporator and reduce the surface temperature of the indoor heat exchanger below freezing point when the cleaning operation is executed, and functions (S130, S132, S134) for, when the freezing control is being carried out, driving the indoor fan in a prescribed period shorter than the execution period of the freezing control and stopping the indoor fan other than the prescribed period.
