Beschreibung
Zusammenfassung:	A CPU 210 receives suction pressure PL and a suction temperature Te, calculates a saturation temperature corresponding to the evaporation pressure Tsl by using the suction pressure PL, and calculates a suction superheating degree SHs of a compressor 21 by using the suction temperature Te and the saturation temperature corresponding to the evaporation pressure Tsl. The CPU 210 reads a current opening degree De of an outdoor expansion valve 24. Next, the CPU 210 uses the received suction pressure PL and opening degree De of the outdoor expansion valve 24 and the calculated suction superheating degree SHs, refers to an outdoor fan control table 300, and determines a control aspect of an outdoor fan 27. The CPU 210 executes control of the outdoor fan 27 in accordance with the control aspect that is determined by referring to an outdoor fan rotational speed table 400.
