Abstract

The solar heating and cooling system simulation platform has been established based on Trnsys in this paper. Taken the villa building in cold areas of China as research objects, the solar heating and cooling system with different solar energy resources division have been analyzed. System optimization designs have been proposed and the optimum storage tank volume and solar fraction of the solar heating and cooling system have been given. The results show that the solar irradiation is one of the most influence factors in solar heating and cooling system for storage tank volume and solar fraction. The higher solar irradiation can be acquired, the larger volume of storage tank and solar fraction.
