WIPO Patent Application WO/2011/093212

Kind Code:

A1

Abstract:

Disclosed are an air conditioner and an air conditioner control method capable of preventing the attachment of dew during cooling operation in the single-type indoor units used in a multi-type air conditioner. The air conditioner is provided with a control unit (7), which controls the discharge refrigerant flow rate of a compressor (21) which circulates a refrigerant, and a storage unit, which stores information relating to the single indoor units (4A, 4B, 4C and 4D) and also stores the indoor maximum request flow rate, which is the maximum discharge refrigerant flow rate which can be requested to the compressor (21). In the control unit (7) is stored the outdoor maximum request flow rate which, less than the indoor maximum request flow rate, is the maximum discharge refrigerant flow rate and set on the basis of information obtained from the storage unit (45). The control unit (7) controls the discharge refrigerant flow rate on the basis of the outdoor maximum request flow rate when, during cooling operation, the temperature of the air sucked into the single indoor units (4A, 4B, 4C and 4D) reaches or exceeds a prescribed air temperature and a prescribed interval elapses.
