In the field of heating, ventilating and air-conditioning (HVAC) engineering, electricity has been used to power air-conditioning and refrigeration systems for a century. In the near future, solar cooling will be an important alternative in air-conditioning and refrigeration, since electricity costs will rise continuously due to escalating oil prices. The choice of solar collectors used in solar cooling systems directly affects the system performance since the required driving temperatures are different. Flat plate collectors, evacuated tubes, solar concentrators, and solar air collectors are the common types for solar thermal systems. It is important to understand their performances in response to different system design and operating requirements based on the irradiation, climatic, and loading conditions in Hong Kong. This project aims to identify the feasible choice for solar cooling systems. Since the investigators do not have any experimental setups, the plant simulation program TRNSYS, which has the modularity of component models, will be used to conduct this comparative study. The results of this project will be a good basis for the ongoing study of solar cooling in the context of Hong Kong and sub-tropical climates.
