Abstract
PURPOSE: To prolong an operating time following the approach of a room temperature to a set temperature and reducing a load on a compressor to improve operating efficiency by reducing a capacity of the compressor sequentially step by step during the descending of a room temperature to a set temperature.
CONSTITUTION: The output voltage of an arithmetic amplifier OA1 for a room temperature detection circuit 11a is represented by V0(θ), a reference voltage on comparison circuits CP2WCP4 by Vs2WVs4 and a room temperature by θ. For instance, through operation of a compressor, it will be 28>θ>27.5, V0(θ) will be Vs3> V0(θ)<Vs2. The output of the comparison circuits CP3, CP4 will be "L" level. In the meantime, the output of CP2 will remain "H" level and the output of "NOR" gate 22 will be "L" level at a rate of one minute of period instead of three minutes because a one-minute counter 20 is set. An electromagnetic valve 3 for hot gas bypass is opened at 2/3 of the three minutes of period. Thus as a room temperature approaches a set temperature, a load on a compressor is reduced, improving operating efficiency.
