This paper is to study the variable frequency control against the compressor and the cooling fan of an air-cooled chiller, and continues to measure and collect the actual operating data, by use of such data as the chilled water supply/return temperature, chilled water flow rate, power consumption, and ambient wet-bulb temperature to conduct the COP analysis of the air-conditioning system. The experimental results show that proper use of the frequency converter to change the operation frequency of the compressor and of the cooling fan indeed can effectively enhance the COP of the air-cooled chiller operation, and reduce the power consumption of the compressor and the cooling fan of the air-cooled chiller to achieve the energy-saving effect.
