Abstract

PURPOSE: To lengthen the life of a refrigerating plant, by keeping indoor temp at set temp highly accurate by controlling output from a compressor in response to the load of refrigeration while reducing the frequency of the start and stop of a motor of the compressor.
CONSTITUTION: This device is provided with a comparator 5 for comparing output from a detector 3, such as, a thermistor, etc., which are mounted to a suction port, etc. of an air conditioner and put out output voltage corresponding to the coil temp of the suction port, the quantity of electricity corresponding to the load of refrigeration, and the set output of a set output instrument 4 as well as a control signal output instrument 6 for putting out a control signal based on a fixed control characteristic of a control signal corresponding to the quantity of deviation electricity E, the output by the control signal corresponding to E. A correction input regulator 9 is mounted which can correct an intercept value of the control signal in the control characteristic of the output instrument 6, thus correcting said intercept value in response to the rariation of said quantity of deviation electricity E, then controlling the capacity of a compressor 1.
