ROTATION CONTROL OF COMPRESSOR FOR AIR CONDITIONER

摘要

PURPOSE:To improve the energy consumption efficiency and to reduce the fault, by providing a pressure sensor for sensing the delivery pressure of a compressor and rotating the compressor with high rotation when the delivery pressure is low while operating with low rotation when the delivery pressure is high. CONSTITUTION:A pressure sensor 9 for sensing the delivery pressure of a variable rotation rotary compressor 1 and producing the continuous signal proportional to the pressure is provided, to control the rotation such that the compressor is operated with high rotation when the delivery pressure is low while it is operated with low rotation when the delivery pressure is high to maintain the constant pressure and the compressor is stopped at both low and high pressure side only when the pressure varies over said control width.
