    摘要： An air conditioner control method may entail measuring an evaporator first temperature at an exit side of the evaporator, maintaining the evaporator first temperature, measuring a length of time that the evaporator maintains the evaporator first temperature, providing a user-set evaporator target temperature; and reducing a rate of refrigerant compressed by a compressor based on a relationship between the length of time that the evaporator maintains the evaporator first temperature and the evaporator target temperature. Furthermore, an air conditioner control method utilizing a condenser and a cold storage unit may entail turning off an air conditioner compressor, maintaining operation of a condenser cooling fan, closing a thermostatic expansion valve, opening a bleed port to bypass the thermostatic expansion valve, and receiving a liquid refrigerant into the cold storage unit from the condenser after the refrigerant passes through a thermostatic expansion valve bleed port and the evaporator.

    摘要： An air conditioner includes a fixed displacement-type first compression mechanism and a variable displacement-type second compression mechanism independent from each other in a refrigeration cycle, and further includes second compression mechanism displacement control means, compression mechanism operation switching control means, an evaporator for refrigerant, a condenser, a blower, evaporator temperature detection means, and evaporator target temperature calculation means. When the refrigeration cycle is operated only by the first compression mechanism, referring to a temperature (Teva) detected by the evaporator temperature detection means, a temperature (Toff) calculated by the evaporator target temperature calculation means and a predetermined value A, if a condition of Teva−Toff≧A is satisfied, both compression mechanisms are operated simultaneously. The condition of required cooling ability is properly determined, an optimum control for air conditioning is realized, and the loss of consumption power and the like can be adequately suppressed.
