Performance Simulation of a Solar Thermal Driven Air Conditioning System with the Evacuated Tubular Solar Collectors

摘要

This paper presents a modelling and simulation of the solar thermal driven air conditioning system with evacuated tubular solar collectors (ETSC) which has been designed for the cooling of reading rooms at cultural centre building located in Gwangju Korea. System consists of mainly six components as an array of ETSCs, three thermal storage tanks (solar, hot water, and cold water storages), absorption refrigerator, auxiliary heater, heat exchangers, circulating pumps. The modelling and simulation of the present ETSC solar system with 10RT capacity is carried out by using the TRNSYS. With an hourly variation of the heating and cooling load demands, complicated control algorithm for designed thermal energy supply of each heating, cooling, and hot water is implemented by the TRNSYS programming. And full one year simulation is conducted for the prediction of the performance of ETSC solar heating and cooling system as one year term under the weather conditions of Gwangju Korea.
