Abstract

PURPOSE: To increase the exchanged heat amount by a method wherein a plurality of heat exchangers in which a plurality of tubes are installed in parallel and fins are arranged between the adjacent tubes and the both ends of the respective tubes are interconnected to a pair of hollow headers are installed in parallel at the front and rear of the air flow direction.
CONSTITUTION: A duplex heat exchanger H consists of the front heat exchanger A at the windward and the rear heat exchanger B at the leeward which are arranged in two parallel stages of the front and rear in the flow direction W of the air for heat exchangers. The front heat exchanger A is equipped with a plurality of tubes 1 arranged in the upper and lower directions in horizontal condition, corrugated fins 2 between adjacent tubes 1 and 1, and the right and left headers 3, 4 and the rear heat exchanger B is almost similarly constituted as the exchanger A but the length of tubes 21, however, is set to be longer than that of tubes of the exchanger A. Refrigerant is let to flow from the rear heat exchanger B to the front heat exchanger A and during the refrigerant flows through respective tubes of the exchangers A, B, heat is exchanged between the refrigerant and the air flowing in the direction indicated by the arrow W.
