Abstract
PURPOSE: To achieve accurate control of compressor output according to the total load of room-side units, to keep optimal ratio between power consumption of compressor and refrigeration performance, and to reduce the power consumption.
CONSTITUTION: In a system comprising one outdoor unit 1 and plural room units 2 connected together through connection pipes, a temperature difference output means 15 is provided in each room units 2. The means 15 detects the difference between the room temperatures and a set point, and the output signal of the means 15 is fed to an integrator 16 fitted in the outdoor unit 1. The unit 1 is fitted with a comparator 17 which compare the output of the integrator 16 with a comparison signal. The output of the comparator 17 is used for controlling a compressor 4. A decision circuit 27 with a latch circuit is provided to feed a stop signal to a control relay 29 when the difference signal from the means 15 is smaller than a predetermined value.
