【発明の名称】空気調和機の周波数制御方法
Document Type and Number:
Japanese Patent JPH0789754
Kind Code:
B2
Abstract:
PURPOSE:To operate an air conditioner at the maximum frequency simultaneously upon starting by predicting a previous current value by a past current history to control the operation so that the current value of the conditioner does not exceed the maximum control current range. CONSTITUTION:A current value memory 12 sequentially replaces the value input by a register 11 with new current value. A calculator 13 calculates a current value IT after a predetermined time T by the register 11 and the memory 12. A frequency increase/decrease designating unit 15 designates the increase or decrease in the frequency on the basis of the output of the calculator 13 and the output of upper and lower current value memory 14. Thus, even if it is operated with the operating frequency at the maximum value from the initial of starting, it can not only prevent the operation from stopping due to an interruption but perform an effect against the abrupt change of a load, and can operate with the maximum capacity of an air conditioner.
