Abstract

A per capital air conditioner energy consumption calculating method in a public building relates to the energy-saving technical field and aims to solve the technical problem of improving the calculating accuracy. The method is that an air conditioner load curve, an indoor temperature curve, an outdoor temperature curve and a curve of the number of people in the building of one day in the previous year in the public building are firstly acquired; secondly, all continuous curve sections that meet 5 conditions are found out on the indoor temperature curve in the day of the previous year; thirdly, the per capital air conditioner energy consumption in per unit of time of each curve section is calculated; and finally, the average valve of the air conditioner per capital energy consumption in per unit of time of all the curve sections is used as the per capital air conditioner energy consumption in per unit of time in the building. Thus, the method provided herein is suitable for air conditioner systems in office buildings.

Description

technical field [0001] The invention relates to energy-saving technologies, in particular to a method for calculating energy consumption of air conditioners per capita in public buildings. Background technique [0002] Air conditioners in public buildings are large energy consumers. Calculating the per capita energy consumption of air conditioners can predict the change of air conditioner load, and promote operators to adjust the operation mode of air conditioners. It is used to precisely control the operation mode of the air conditioner to ensure a good balance between environmental comfort and energy saving and environmental protection. [0003] Air-conditioning energy consumption includes energy consumption of auxiliary air-conditioning equipment, building energy loss and air-conditioning energy consumption of building personnel. From the perspective of accurate estimation of building air-conditioning energy consumption, the reasonable arrangement of air-conditioning pow...
