摘要： An air conditioning system comprising an outdoor unit in which a compressor is driven by the power supplied from a variable-frequency power supply and a plurality of indoor units operatively connected to the outdoor unit. Each indoor unit has a circuit for generating a frequency signal to be applied to the variable frequency power supply of the outdoor unit in response to a set room temperature and a temperature detected. In response to the frequency signals transmitted from the indoor units, the control unit of the outdoor unit detects a maximum frequency, a minimum frequency and the number of operating indoor units and determines the operating frequency of the variable frequency power supply in response to the maximum and minimum frequencies and the number of operating indoor units. The control unit includes a decision circuit which responds to the frequency signals transmitted from the indoor units so as to detect a maximum frequency, a minimum frequency and the number of operating indoor units, a circuit which responds to thus obtained maximum frequency and the number of operating indoor units so as to determine an operating frequency which is to be corrected, a circuit for obtaining a correction value, which is used to correct the operating frequency, in response to the difference between the maximum and minimum frequencies and a circuit for determining an operating frequency to be applied to the variable-frequency power supply by subtracting the correction value from the operating frequency to be corrected.

摘要： An air conditioning apparatus comprising an indoor unit. The unit has a first indoor heat exchanger for cooling or heating indoor air and a second indoor heat exchanger for cooling or heating indoor air. A first indoor fan is located near the first indoor heat exchanger, for drawing the indoor air and supplying it through the first indoor heat exchanger to the zone of a room. A second indoor fan is located near the second indoor heat exchanger, for drawing the indoor air and supplying it through the second indoor heat exchanger to the zone of a room. The apparatus further comprises two temperature sensors for detecting the temperatures of the indoor heat exchangers, respectively. The higher or lower of the temperatures detected by the sensors is selected, in accordance with the cooling or heating mode in which the apparatus is operating. In accordance with the temperature selected, the air-supplying rates of the indoor fans are controlled.
