Webinar: Key technology for the innovative decarbonised heating and cooling systems

The presentation addressed the key technologies that enable solar driven and decarbonised heating and cooling systems for buildings to operate in efficient and effective ways. In terms of the 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. The double-sourced, vapour injection and enthalpy increasing heat pump was applied to provide match-up heat to the solar panels array, with the particular features of zero-bill defrosting. In terms of the decarbonised cooling, the innovative super-performance dew point cooling involving advanced fibre materials, superior thermal-assisted pressing approach for bonding of the fibre 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.
