Abstract
PURPOSE: To enhance the operability by detecting the temperature of an evaporator or the corresponding refrigerant pressure, stopping operation of a compressor is the detected temperature (pressure) is lower than a set level and operating the compressor again automatically if a fan is operating at a low speed thereby eliminating unnecessary service inspection. CONSTITUTION: A compressor 1 is operated with increased power supply frequency if the difference of the temperature in a conditioning room 7 detected by an indoor temperature sensor 8 from the set temperature of a client is high, otherwise it is operated with decreased power supply frequency. If the temperature of an evaporator 4 drops below a set level during operation, a stop means 13 receives a detection signal from a sensor 11 and stops operation of the compressor 1. If a fan 6 is operating at a high speed, a decision is made that the operation is abnormal and an alarm is delivered. If the fan 6 is operating at a low speed, a decision is made that an easily freezable state is simply brought about due to evaporation pressure drop and the compressor 1 is operated again automatically after it is stopped for 3 min through a restart prevention timer.
