Air conditioner

Abstract

In an air conditioner, in a general cooling mode, an indoor air is cooled by heat exchange with a main evaporator of a first refrigerant, while in a rapid cooling mode, an indoor air is cooled by heat exchange with an intermediate heat exchanger consisting of a main evaporator of the first refrigerant and a rapid cooling condenser of a second refrigerant and then re-cooled in a rapid cooling evaporator of the second refrigerant, thereby performing a cool and pleasant cooling operation immediately whenever necessary.
