Abstract (en)
[origin: EP0909927A2] In a control system, single cycle-controlling PC board is mounted on a housing. The single cycle-controlling PC board is selected from cycle-controlling PC boards previously produced according to refrigerant flow paths in the refrigerant cycle, respectively. Each of the cycle-controlling PC boards has a sensor circuit for reading a detected signal of a sensor for detecting a temperature of a heat exchanger and a valve control circuit for operating a switch control of a switching valve and an opening control of an expansion valve according to corresponding one of the refrigerant flow paths. Single motor-controlling PC board is mounted on the housing. The motor-controlling PC board is selected from motor-controlling PC boards previously produced according to air conditioning abilities and inputted power supply voltages, respectively. Each of the motor-controlling PC boards has a motor control circuit for controlling a rotational frequency of a compressor motor and a speed of rotation of an outdoor fan according to corresponding one pair of the air conditioning abilities and the inputted power voltages. Communication circuit electrically connects the one cycle-controlling PC board and the one motor-controlling PC board so as to communicate signals to each other. <IMAGE>
