Abstract: The existing refrigeration technology faces the challenges of huge energy consumption and environmental disruption. Adsorption refrigeration is attractive as an alternative solution of refrigeration technology due to the possibility to use low grade heat and green refrigerants (i.e. water, ammonia and methanol). Solar cooling and low grade waste heat utilization are the main applications of adsorption refrigeration but it is limited by the disadvantages of low efficiency, large size and high investment. This talk will focus on current situation, methods of efficiency improvement, challenge of economic benefit and typical project cases of adsorption refrigeration technology for solar cooling and low grade waste heat utilization. Emerging applications, like ultra-low waste heat recovery of data center and fuel cell, are especially concerned. This talk will also give a brief introduction on the recent progress of research of adsorption refrigeration, especially the rapid development of adsorbent materials.
