Abstract
A control system for controlling an air conditioning system having a variable delivery compressor and an evaporator for cooling and dehumidifying air supplied thereto from a blower. The control system comprises sensor means for sensing the evaporator boiling pressure, determining means for determining whether or not the detected value of evaporator boiling pressure has reached either a predetermined upper limit or a predetermined lower limit, and control means for controlling the capacity of the compressor over its maximum variable range and also the quantity of air supplied from the blower so as to maintain the evaporator boiling pressure at one of the predetermined upper and lower limits which is determined to have been reached by the detected boiling pressure value.
