An air conditioner includes a plurality of refrigerant compressors, a plurality of ventilating fans and a cooling/warming water pump which is controlled by both a memory and a contact-less control unit in accordance with an outdoor temperature and a refrigerant temperature which are sensed by associated temperature sensors. Alternatively, the control unit may be connected to both protective devices disposed on the fans, the compressors, the pump, etc. and further connected to a digital indicator which indicates the operating status of the air conditioner.
