Study on Calculation Method of Baseline Electricity Consumption of Air-conditioner in Base Station

As the energy retrofit of the air-conditioning system in the base stations is conducted by using Energy Management Contract mode,the accurate calculation of the baseline energy consumption is critical for determining the energy savings.In this paper,the real-time energy consumption of the air conditioning system in the base stations made by 90 mm color steel plate in Zhongshan City is measured.A novel calculation method of the baseline electricity consumption is proposed based on the measured data,including the total electricity consumption in the base station,the electricity consumption of the air conditioning and fresh air system,the indoor and outdoor temperature.This method is validated by comparing the calculated baseline electricity consumption to the measured result.The effects of the data-collection duration and the air temperature on the calculated results are analyzed,and then the optimal calculation scheme is obtained.It is shown that the proposed method provide a convenient and accurate way to calculate the baseline electricity consumption of the air conditioner.This research is of significance for the determination of the energy savings in base stations.
