METHOD AND DEVICE FOR IMPROVING AIR-CONDITIONING SYSTEM APPLYING ALL-WEATHER SOLAR ENERGY HEAT SUPPLY

摘要

A method for improving an air-conditioning system applying an all-weather solar energy heat supply. The method comprises: in an air-conditioning system comprising an original single-function cooling air-conditioning main apparatus (1) combined with a cooling tower (2) and a boiler (3), utilizing a plate heat exchanger (9), a solar energy heat collecting plate (13) and an energy storing tank (14) and adding recycling pipes; absorbing heat of air in winter by utilizing the cooling tower (2); absorbing solar energy heat by utilizing the solar energy heat collecting plate (13) and transferring the heat to the plate heat exchanger (9); absorbing heat of an antifreeze solution by utilizing the single-function cooling air-conditioning main apparatus (1); and configuring the plate heat exchanger (9) to form a secondary loop to prevent the antifreeze solution from freezing, thus supplying heat to an interior without starting the boiler (3) when the outside temperature is above five degrees. The method adds a function of supplying heat in winter without changing an original system and while maintaining operational performance of the original system used in summer, improves the utilization of the single-function cooling air-conditioning main apparatus (1) and the cooling tower (2), and greatly reduces a usage time of the boiler (3), thereby improving energy utilization and reducing environmental contamination.
