Abstract

The paper addressed several key technologies that enable solar driven heating and cooling systems for buildings to operate in efficient and effective ways. In terms of the solar heating, the multiple-throughout-flowing featured panels-array in combination with micro-channel structure for individual panels are the most creative technologies that has proven to be able to achieve 10% higher solar thermal efficiency and 100% higher energy efficiency ratio compared to the existing solar thermal system. In addition, the coupled heat storage/exchanger with the double containers is able to speed up heating time and increase the heat transfer capacity of the system, and is regarded as an additional initiative. The cost balance approach is applied to determine the quantity and area of the PV panel, leading to a new way of achieving the zero-bill heating operation in an economic way. In terms of the solar cooling, the innovative super-performance dew point cooling involving advanced fiber materials, superior thermal-assisted pressing approach for bonding of the fiber material with dry side material, as well as intelligent control of the pump and fan is detailed. Furthermore, the solar driven adsorbent bed cyclic system using the solar radiation and solar based microwave energy was introduced. Recent Publications 1.
