Figure 2. The higher the cooling efficiency factor, the more efficient the air conditioner.


More efficient air conditioners have higher cooling efficiency factors. As an example, assume an enclosure air conditioner operating at 460 V and 60 Hz. Cooling capacity 95/95 and 60 Hz is 2,700 W. Power consumption at 95/95 and 60 Hz is 1,500 W. To calculate the cooling efficiency factor, divide cooling capacity (2,700 W) by power consumption (1,500 W), which yields a cooling efficiency factor of 1.8.
