AIR CONDITIONING CONTROL DEVICE

摘要

PURPOSE: To provide an air conditioning control device under a less-expensive configuration which can turn off an air conditioning load during both heating operation and cooling operation at a set value, without using an expensive microcomputer. CONSTITUTION: There are provided a comparator 1 for comparing a set value with a room temperature measured value and outputting a result of comparison; a hysteresis circuit for feeding back an output of the comparator to an input side and having an operation interval T; a first switch means 3 arranged in this hysteresis circuit; a second switch means 7 arranged in an air conditioning load circuit; and a cooling or a heating discriminating means 10 for intermittently controlling the first and second switch means 3, 7 in response to an output signal of the comparator 1 and a cooling or a heating changing-over signal.
