On the other hand, when the pressure equalization operation is started, the fan 2
5, and temperature detection means 2 that detects the temperature on the high pressure side of the refrigerant.
3, the pressure equalization operation is started when the temperature on the high pressure side of the refrigerant detected by the temperature detection means 23 falls below a predetermined temperature that does not cause intense pressure equalization noise during the pressure equalization operation; An air conditioner characterized by being equipped with pressure equalization operation control means. (2) In an air conditioner that performs pressure equalization by connecting the high-pressure side refrigerant pipe and the low-pressure side refrigerant pipe without an expansion valve when the system is stopped, determine whether the system is in a stopped state. an operation stoppage determination means; and when the operation stoppage determination means determines that the operation is in a stoppage state, the condenser fan 25 is rotated at a predetermined rotation speed prior to the pressure equalization operation, while the pressure equalization operation is performed. The above fan 2 if started
5; a timer for measuring the elapsed time after the operation has been determined to be in a stopped state by the operation stop determination means; An air conditioner characterized by comprising a pressure equalization operation control means that starts the pressure equalization operation when a predetermined time period is reached until the pressure reaches a level that does not produce intense pressure equalization noise during the pressure equalization operation.
