OPERATION CONTROLLER FOR AIR CONDITIONER

摘要

PURPOSE:To maintain excellent deodorizing performance for a long period by correcting an operation cumulative time in response to an odor adsorption amount of a deodorizer due to a difference of number of operating times of a blower motor in an indoor side unit, comparing the corrected time with a set operation cumulative time, and controlling a heater. CONSTITUTION:Correcting operation cumulative time calculating means 7 corrects an operation cumulative time (ta) in response to an odor adsorption amount of a deodorizer generated due to a difference of number of operation times of a blower generator in an indoor side unit from starting of an operation of an air conditioner. Operation cumulative time comparing means 9 compares the corrected correcting operation cumulative time (ts) with a set operation cumulative time (t1), and suction temperature difference comparing means 13 compares a differential temperature (DELTAt) of upper and lower limit values of the suction temperature of the conditioner with a set suction temperature difference (DELTAT). Heater operation control means 14 controls an operation of a heater based on a comparison result of the means 9 with the means 13. Thus, excellent deodorizing performance can be maintained for a long period.
