Abstract
An air conditioner is made to follow up a change in load in an efficient manner by utilizing the fact that the components of a three-component mixed medium serving as a substitute for Freon have different boiling points. The mixed medium, which consists of R-32, R-125 and R-134a, is sealed within the circuit of the air conditioner, and a supercooled heat exchanger and liquid-gas tank are interposed between an outdoor heat exchanger and an expansion valve. The liquid-gas tank is connected to an accumulator via a liquid injection valve.
