摘要： An air-conditioner of a heat pump type includes a refrigeration cycle including an interior heat exchanger, an exterior heat exchanger, a compressor, a four-way valve, and an expansion mechanism, and a non-azeotrope refrigerant composed of not less than two kinds of refrigerants is used as a working medium. A refrigerant path in each of the interior and exterior heat exchangers is divided into a group of first refrigerant passages located at a region where a proportion of the liquid-phase refrigerant is large and a group of second refrigerant passages located at a region where a proportion of the liquid-phase refrigerant is small. At least part of the group of first refrigerant passages of each of the interior and exterior heat exchangers is located at the windward side. Heat transfer tubes of the group of first refrigerant passages of each of the interior and exterior heat exchangers are smaller in flow-passage cross-sectional area than those of the corresponding group of second refrigerant passages.

摘要： In a heat transfer tube for a zeotropic refrigerant mixture, the inner surface of the tube in which the zeotropic refrigerant mixture flows is formed with grooves having cross portions where the grooves intersect with each other, or the inner surface of the tube is formed with a plurality of independent projections. Thus, concentration boundary layers generated in the zeotropic refrigerant mixture are stirred to reduce the thickness of the concentration boundary layers, thereby decreasing the diffusion resistance and promoting the stirring effect. Consequently, there can be provided a heat transfer tube for a zeotropic refrigerant mixture which exhibits a high heat transfer performance, and a heat exchanger of a cross-fin tube type, a refrigerator and an air conditioner which include such heat transfer tubes.

摘要： Disclosed is an air conditioner and, in particular, an air conditioner which is capable of blowing out warm air in heating mode. In the air conditioner of this invention, the condenser is thermally separated into an air-upstream-side and an air-downstream-side heat exchanger, and the heat exchange capacity of the air-downstream-side heat exchanger is adjusted, so that, under preset operating conditions, the entire refrigerant in the air-downstream-side heat exchanger can be kept in the superheated-gas phase, thus making it possible to blow out warm air having a temperature higher than the condensation temperature. Further, the refrigerant temperature at the outlet of the air-downstream-side heat exchanger is measured by a temperature sensor, and the revolving speed of the compressor, the revolving speed of the fan, etc., is so controlled that the temperature measured is kept at a level higher than the condensation temperature. Thus, under all operating conditions, the entire refrigerant in the air-downstream-side heat exchanger can be kept in the superheated gas phase, thereby making it possible to blow out warm air having a temperature higher than the condensation temperature.
