Abstract
An air conditioner control apparatus measures coolant temperatures and pressures at both inlet side and outlet side of a compressor, or detects a electric capacity of the coolant and the like in order to determine the kind of coolant. For example, when a CPU 31 detects that the coolant R22 is used, the apparatus selects a data item of a fluorocarbone-based coolant R22 stored in a data selection means 35 storing pressure-temperature data items, and calculates a super-heated rate or a super-cooled rate according to the ability of a compressor 1 so that the room temperature reaches the predetermined one set by the operator and setting a calculation result. Next, a vapor temperature is calculated by each indoor air conditioner side, and during a cooling operation, electronic expansion valves 9, 11 are controlled so that target super-heated temperature are reached to the temperatures in temperature sensors 17 and 19.
