Abstract

PURPOSE: To simplify mechanical movable portion and reduce power consumption, by controlling simultaneously the revolution speed of an electric motor and liquid impregnation pump by means of output of detector thermal provided to detect increase and decrease of the heat load through variable voltage frequency converter.
CONSTITUTION: An intake pressure detector 4 to detect the increase and decrease of cooling heat load is provided on the intake portion of a compressor 1, and the output of the intake pressure detector 4 is inputted in a variable voltage frequency converter 7 by way of a pressure regulator 5, and further the revolution speed of a compressor driving alternating current motor 3 and liquid impregnation pump driving alternating current motor 10 are controlled simultaneously. Thereby, mechanical movable portion is simplified and power consumption can be reduced, since sliding and throttle valves become unnecessary, which are arranged for controlling speed increasing gear train and compressed volume.
