摘要： The invention provides a fin-and-tube heat exchanger using a return bend tube that allows further enhancement of the evaporative performance of the heat exchanger. The fin-and-tube heat exchanger, where a refrigerant is supplied inside tubing, has a hairpin tube portion where a plurality of hairpin tubes are arranged, a return bend tube portion where there are arranged a plurality of return bend tubes joined to respective hairpin tube ends of the hairpin tube portion, and a fin portion comprising a plurality of fins arranged at a predetermined spacing on the outer surface of the hairpin tubes. The heat exchanger comprises first grooves formed on the tube inner surface of the return bend tube. A first groove pitch (P1) of the first grooves in a cross section perpendicular to a tube axis, and a second groove pitch (P2) of spiral-shaped second grooves formed on the inner surface of the hairpin tube in a cross section perpendicular to a tube axis, satisfy a groove pitch ratio (P1/P2) of 0.65 to 2.2, while a first groove cross-sectional area (S1) per groove of the first grooves in a cross section perpendicular to the tube axis, and a second groove cross-sectional area (S2) per groove of the second grooves in a cross section perpendicular to the tube axis satisfy a groove cross-sectional area ratio (S1/S2) of 0.3 to 3.6.

摘要： An apparatus (100) includes a compressor (110), a load (130), a heat exchanger (120), and a heater. The compressor (110) compresses a refrigerant. The load (130) uses the refrigerant to remove heat from a space proximate the load. The load (130) sends the refrigerant to the compressor (110). The heat exchanger (120) receives the refrigerant from the compressor (110). The heat exchanger (120) transfers heat from a fluid to the refrigerant. The heat exchanger (120) discharges the refrigerant to the compressor (110). The heater adds heat to the fluid.

At least one of a first heat exchange unit (3a) and a second heat exchange unit (3b) has a refrigerant inlet disposed leeward of air passed by the fan (8a) and a refrigerant outlet disposed windward of the air. Refrigerant flows successively through the first heat exchange unit (3a) and the second heat exchange unit (3b) when the first heat exchanger (3) is used as an evaporator, and flows in parallel through the first heat exchange unit (3a) and the second heat exchange unit (3b) when the first heat exchanger (3) is used as a condenser.
