Outdoor heat exchange block C in which 22 and outdoor fan 23 are arranged
Is not heated during the heating operation, and has a temperature substantially equal to the outside air temperature. Therefore, the refrigerant in the heating cycle easily flows in, and the refrigerant accumulated in the outdoor heat exchanger 22 is again heated in the heating cycle. Therefore, there is a problem that the number of pump down operations that inevitably operate the compressor 24 for a fixed time increases.
また、ポンプダウン運転中は、一時的に暖房運転が停止

雪、雨などが室外熱交換器22に付着した場合蒸発しにく
いので、耐食劣化が生じて熱交換性能が低下するという
問題もあり、また室外ファン23に付着している雪などの
ために運転がロックされた状態となり、モータが損傷す
るという問題もあった。In addition, since the heating operation is temporarily stopped during the pump down operation, there is a problem that discomfort increases. further,
When snow, rain, etc. adhere to the outdoor heat exchanger 22, it is difficult to evaporate, so there is also the problem that corrosion resistance deteriorates and the heat exchange performance deteriorates. There was also a problem that the motor would be locked and the motor would be damaged.
そこで本発明は、ポンプダウン運転の回数を減少し得る
とともに室外熱交換器の耐食劣化による熱交換性能低下
の防止を図る空調機器における室外ユニットを提供する
ことを目的とする。Therefore, an object of the present invention is to provide an outdoor unit in an air conditioner that can reduce the number of pump down operations and prevent deterioration of heat exchange performance due to corrosion resistance deterioration of the outdoor heat exchanger.

とえ雪や雨が付着した場合でもすぐに乾き、耐食劣化が
少なくなるともに、暖房回路中の冷媒の室外熱交換器へ
の漏れ込む量が少なくなる。Operation According to the above configuration, during the heating operation, the refrigerant heater heats and evaporates the refrigerant, and the high-temperature refrigerant gas is conveyed to the indoor unit by the compressor to obtain the heating effect. In addition, since the outdoor heat exchanger and the outdoor fan are placed above the refrigerant heater, even if these devices are heated and snow or rain adheres, they will dry quickly and corrosion deterioration will be reduced, and at the same time in the heating circuit. The amount of refrigerant that leaks into the outdoor heat exchanger is reduced.
