Abstract (en)

There is provided an evaporator of a refrigeration cycle apparatus in which a non-azeotropic refrigerant mixture is enclosed, the evaporator improving frost proof performance and heat exchange performance. If the opening side of a cutout is present on the windward side of an airflow, a difference between an air temperature and an evaporator surface temperature is large, which improves heat exchange performance but easily causes frost. Conversely, if the opening side of the cutout is present on the leeward side, frost proof performance is improved but heat exchange performance is degraded. In particular, since a non-azeotropic refrigerant mixture is used as a refrigerant, the refrigerant temperature tends to decrease on the inlet side of the evaporator due to a temperature gradient, and frost is easily generated. However, since a first heat exchange section (23a) in which the opening side of the cutout is positioned on the leeward side in the airflow direction is formed, it is possible to improve frost proof performance by providing the first heat exchange section (23a) at least on the inlet side of the evaporator.
