Method for predicting office building cooling load

Abstract

The invention belongs to the technical field of building cooling load control, relates to a method for predicting an office building cooling load, and through building an office building outdoor cooling load model, an office building indoor cooling load model and an office building fresh air load hourly variation model, an office building cooling load model is obtained. Based on the an energy conservation law and a thermal balance relation in building environment, from the point of view of variation of the number of people in an office building and personnel energy utilization modes, the interference amount of a cooling load in the office building is predicted and analyzed; and meteorological website data are utilized to predict a cooling load outside the office building and an office building fresh air load. The method for predicting the office building cooling load establishes an air conditioner enclosing structure, a solar radiation cooling load hourly variation model, and hourly variation models of personnel, equipment, illumination cooling loads and personnel indoor rate in air conditioning environment, and finally obtains a cooling load prediction model of the office building.

Description

technical field [0001] The invention belongs to the technical field of building cooling load control, and in particular relates to a prediction method for office building cooling load. Background technique [0002] With the continuous advancement of my country's economic growth and urbanization process, the demand for energy is also increasing rapidly. Building energy consumption is close to one-third of the total energy consumption of the society, and building energy conservation is an important topic for achieving energy conservation and emission reduction goals. At present, the relatively common load estimation method in the industry is the area index method. Although this method can be applied to the estimation of most building loads, the estimation is too rough, which often leads to large load design values ​​and low operating efficiency, resulting in unnecessary of energy waste. Prediction of heating and air conditioning load is the basis for accurately configuring e...
