然的に圧縮機２４を一定時間だけ運転するというポンプ
ダウン運転の回数が増加するという問題があった。Problems to be Solved by the Invention However, according to the above conventional configuration, the outdoor heat exchanger block C in which the outdoor heat exchanger 22 and the outdoor fan 23 are arranged is not heated during the heating operation, and is not heated. The temperature becomes almost the same as the outside air temperature, and therefore the refrigerant in the heating cycle easily flows in. It becomes necessary to return the refrigerant accumulated in the outdoor heat exchanger 22 to the heating cycle, and the compressor 24 is inevitably turned off for a certain period of time. There has been a problem in that the number of pump-down operations increases.
また、ポンプダウン運転中は、−時的に暖房運転が停止
されるため、不快感が増すという問題もある。さらに、
雪、雨などが室外熱交換器２２に付着した場合蒸発しに

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。Furthermore, during the pump-down operation, the heating operation is temporarily stopped, so there is also the problem that discomfort increases. moreover,
If snow, rain, etc. adhere to the outdoor heat exchanger 22, it is difficult to evaporate, so there is a problem that corrosion resistance deteriorates and the heat exchange performance decreases.Furthermore, snow or rain adhering to the outdoor fan 23 may cause the operation to be interrupted. There was also the problem that the motor would become 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。SUMMARY OF THE INVENTION 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 a decrease in heat exchange performance due to deterioration of the corrosion resistance of an outdoor heat exchanger.

への漏れ込む量が少なくなる。Effects According to the above configuration, during heating operation, the refrigerant heater heats and evaporates the refrigerant, and the compressor conveys this high-temperature refrigerant gas to the indoor unit to obtain a heating effect. In addition, since the outdoor heat exchanger and outdoor fan are placed above the refrigerant heater, these devices are warmed and dry quickly even if snow or rain adheres to them, reducing corrosion resistance and preventing damage to the heating circuit. The amount of refrigerant leaking into the outdoor heat exchanger is reduced.
