Abstract
In an air-conditioning system, during precooling or preheating control, a setting temperature is controlled such that a first temperature difference between the setting temperature and an indoor temperature is not less than a temperature difference at which a compressor performs operation, and the setting temperature is controlled to be changed to a target temperature when a second temperature difference between the indoor temperature and the target temperature is less than the first temperature difference. Since the compressor can be operated in the range from a low capacity to a medium capacity, operation efficiency of the air-conditioning apparatus can be increased, and the energy-saving operation with less power consumption can be realized. Since the operation capacity of the compressor can be readily suppressed with adjustment of the setting temperature, control is facilitated and the precooling control can be incorporated in various types of air-conditioning apparatuses.

18. An air-conditioning apparatus executing a precooling operation or a preheating operation such that an indoor temperature representing a temperature of indoors reaches a target temperature by using a refrigeration cycle including a compressor,
wherein the air-conditioning apparatus controls, during execution of the precooling operation or the preheating operation, a setting temperature of the air-conditioning apparatus such that a first temperature difference between the indoor temperature and the setting temperature is not less than a temperature difference at which the compressor performs operation, and changes the setting temperature to the target temperature when a second temperature difference between the indoor temperature and the target temperature is less than the first temperature difference.

35. An air-conditioning system comprising:
-
an air-conditioning apparatus executing a precooling operation or a preheating operation such that an indoor temperature representing a temperature of indoors reaches a target temperature by using a refrigeration cycle including a compressor; reception means that receives an operation control instruction from outside;
wherein the air-conditioning systemcontrols, during execution of the precooling operation or the preheating operation, a setting temperature of the air-conditioning apparatus such that a first temperature difference between the indoor temperature and the setting temperature is not less than a temperature difference at which the compressor performs operation, and changes the setting temperature to the target temperature when a second temperature difference between the indoor temperature and the target temperature is less than the first temperature difference. - View Dependent Claims (36, 37)
