<p><P>PROBLEM TO BE SOLVED: To provide an air conditioner which can perform cooling operation, and which can suppress an abnormal drop in pressure of a refrigerant gas discharged from a compressor at low outside-air temperature, and can efficiently cool an electric article box loaded with an inverter driving component provided, with radiation fins. <P>SOLUTION: The air conditioner has a refrigeration cycle configured by connecting a compressor 1, a four-way valve 2, an outdoor heat exchanger 3, blowers 23, an outdoor expansion valve 4, and an indoor unit through refrigerant piping. The air conditioner 2 has two blowers 23, and varies the ratio of rotational frequencies of the upper and lower blowers 23 as the total rotational frequency of the blowers decreases at low outside air temperature. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
