Abstract

PURPOSE: To improve the efficiency of a freezing cycle, to reduce the size of an electric part, and to form a product in a compact state by a method wherein the electric part is brought into contact with a part of a heat-exchanger on the outdoor side to conduct the heat from the electric part to the heat-exchanger.
CONSTITUTION: During heating operation, a refrigerant flows as shown by a solid line, heat is emitted by a heat-exchanger 5 on the indoor side, and heat is sucked by a heat-exchanger 3 on the outdoor side to effect heating. Since heat generated from an electric part 6 being a frequency converting device is brought into contact with the heat-exchanger 3 on the outdoor side, heat is derived in a freezing cycle to produce a high-efficient freezing cycle. Meanwhile, during cooling operation, a refrigerant flows as shown by a dotted line, heat is emitted by the heat-exchanger 3 on the outdoor side, and heat is sucked by the heat-exchanger 5 on the indoor side to cool the indoor side. In which case, since the electric part 6 is brought into contact with a condenser but the electric part 6 is brought into a state that its temperature is increased to a value higher than that of the freezing cycle, the heat of the electric part 6 is transferred to the condenser and heat is emitted by the heat-exchanger 3 on the outdoor side.
