Abstract
PURPOSE: To increase the maximum temperature of a compressor side heat exchanger without increasing the pressure resistant property of each of the parts used in a cooling cycle by a method wherein when the pressure of a discharge side coolant exceeds a certain value, the amount of heat exchange function by an evaporator is reduced automatically and the rise of the pressure of the discharge side coolant is controlled.
CONSTITUTION: When the temperature of a fluid rises from a temperature t0, the discharge pressure of the fluid rises up along a curved line h and the pressure of fluid discharge reaches an upper switching pressure PcH of a pressure switching device 11 at a temperature tCH, the contact of the pressure switching device 11 which is provided on the high pressure side of the cooling cycle is switched so that electricity is supplied to the low speed side terminal of a speed motor 12 for a blower 12 and the operation of the blower 12 is switched from high to low to thereby lower the discharge side pressure to be shifted to a curved line 6. Further, a when the temperature of the compressor side fluid rises up to a set pressure PH of the switching element 11, the operation of the compressor 1 is stopped and the temperature tH1 at that time becomes the maximum temperature of the compressor side fluid capable of operating the air conditioner.
