Title:
AIR CONDITIONER
Document Type and Number:
Japanese Patent JP3760259
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To contrive the enhancement of COP (energy consumption efficiency), achievement of a reference value which is a target prescribed by New Energy Saving Law to be achieved by the year 2007, and the reduction of yearly power consumption, by reducing the power consumption of an air conditioner more.
SOLUTION: In an air conditioner where a compressor 81, whose capacity is variably controlled, a condenser 11, an expansion valve 22, and an evaporator 12 are connected in circular form by pipe, the temperature of gas discharged from the compressor 81 is controlled by the opening of the expansion valve 22, and the opening of the expansion valve 22 is controlled, so that the temperature of discharged gas at compressor 81 operation with its lowest capacity is lower than the temperature of the discharged gas at the compressor 81 which is operated with its rated capacity.
