    • There is disclosed a heat exchanger tube for conducting refigerant in a heat exchanger. The inner surface of the tube has a convex portion having a broad tip and a plurality of inner fins. The area of the tip of the convex portion is larger than that of the tip of the inner fins. The height of the convex portion can be set at more than that of the inner fin. A heat exchanger according to the invention has a plurality of plate fins, each having a hole therein. Heat exchanger tubes pass through the holes of the plate fins. A method of manufacturing a heat exchanger comprises the steps of stacking a plurality of plate fins, each having a hole, with a predetermined space therebetween. Heat exchanger tubes are inserted through the holes. Then, the tubes are expanded to engage the plate fins. A refrigerating circuit utilizing a heat exchanger is also described.

    • An air conditioner employs a non-azeotropic refrigerant mixture without deteriorating the heat-exchange efficiency and air-conditioning capability of an indoor heat exchanger of the air conditioner. The indoor heat exchanger (3) has a fin on which a first path (33), a second path (34), and a third path (35) for passing the refrigerant mixture are arranged. The first path passes the refrigerant mixture from the leeward side toward the windward side of an air flow produced by an indoor fan (7), to form a counterflow of the refrigerant mixture against the air flow. The second path passes the refrigerant mixture from the windward side toward the leeward side of the air flow. Although the second path forms a parallel flow of the refrigerant mixture with respect to the air flow, it achieves moderate heat-exchange efficiency because the number of rows of piping on the leeward side is greater than that on the windward side and because the rows of piping do not overlap one another with respect to the air flow. The third path passes the refrigerant mixture from the windward side toward the leeward side and again from the windward side toward the leeward side of the air flow, to partly realize a counterflow of the refrigerant mixture against the air flow, to thereby improve the heat-exchange efficiency.
    • 空调器采用非共沸混合制冷剂,而不会降低空调的室内热交换器的热交换效率和空气调节能力。 室内热交换器(3)具有翅片,第一路径(33),第二路径(34)和用于使制冷剂混合物通过的第三路径(35)布置在其上。 第一路径将制冷剂混合物从室内风扇(7)产生的空气流的背风侧向风向侧通过,以形成制冷剂混合物相对于空气流的逆流。 第二路径将制冷剂混合物从风向侧朝向空气流的背风侧。 虽然第二路径形成制冷剂混合物相对于空气流的平行流动,但是由于背风侧的管道的排数大于迎风侧的管道数量,所以能够实现适度的热交换效率, 管道相对于空气流不重叠。 第三路径将制冷剂混合物从风向侧朝向背风侧,再次从空气流的向风侧朝向背风侧,部分地实现制冷剂混合物相对于气流的逆流,由此, 交流效率。
