Evaluation method for heating utilization of solar energy buildings in the western region

Abstract

An evaluation method for solar energy heating utilization of buildings in the western region is presented. By combining the main passive solar energy heating utilization mode, the calculation and analysis method for solar radiation zoning and solar energy heating utilization efficiency of each zoning in the western region is proposed. The paper presents the spatial distribution of solar energy forarchitectural heating in the western region of China by cluster analysis combined with geographic information visualization technology, taking the solar radiation ratio kV and the solar radiation ratio k Beta of photovoltaic heating degree days as the zoning indexes and 46 representative cities in the western region as the sample. The contribution rate of photovoltaic heating and photovoltaic heating are taken as the evaluation indexes of the heating utilization potential of solar energy buildings in the west of China, and the representative cities of each district are selected to quantify the heating utilization potential of solar energy in each district. As that solar energy photothermal and photoelectric utilization mode are comprehensively considered, the invention highlights the effectiveness of solar energy use for heating residential buildings.

Description

technical field [0001] The invention belongs to the technical field of renewable energy utilization and building energy conservation, and in particular relates to an evaluation method for solar energy building heating utilization in western regions. Background technique [0002] The western regions of my country are rich in solar radiation resources, and most of these regions are located in the severe cold and cold areas of the building thermal division. In the western regions, using solar radiation to solve the winter heating problem has obvious advantages. To carry out research on solar heating in buildings, the utilization rate of solar energy is the key issue in evaluating the effectiveness of heating and the premise to guide the design of solar heating.
