Abstract

An air conditioner cooling quantity dissipation calculation method in an office building relates to the energy-saving technical field and aims to solve the technical problem of improving the calculation accuracy. The method is that an air conditioner load curve, an indoor temperature curve and an outdoor temperature curve of one day in the previous year in an office 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 cooling quantity dissipation rate of the air condition in per unit of time of each curve section is calculated; and finally, the average valve of the cooling quantity dissipation rate of the air conditioner in per unit of time of all the curve sections is used as the cooling quantity dissipation rate of the air conditioner in per unit of time in the office 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 technology, in particular to a technology for calculating the cooling loss of an office building air conditioner. Background technique [0002] Air conditioning in office buildings is a major energy consumer. Calculating the cooling loss of building air conditioning can help you find out whether the building air conditioning enclosure is perfect, can promote the building to take insulation measures, and is beneficial to users in reducing operating costs and reducing expenses. Accurate calculation of the air conditioner is beneficial to accurately control the operation mode of the air conditioner and ensure a good balance between environmental comfort and energy saving and environmental protection. From the aspect of accurate estimation of building air-conditioning energy consumption, the reasonable arrangement of air-conditioning power consumption plan also needs to calculate the cooling loss of buildings. Howeve...
