Compact absorption chiller for solar-driven air-conditioning

摘要

Recently a growing demand for small scale absorption chillers for both solar cooling and trigeneration, i.e. utilization of cogenerated heat for cooling, has been encountered. Up to now, chillers below 35 kW are not available. Thus a 10 kW absorption chiller with water/LiBr as working fluid has been developed and successfully tested within a joint European project. The plant requires water of 80 to 100 ℃ and optimized performance as compared to present standard plants: by means of a careful cycle design and a fully automated control the COP has been increased by about 10 %. Further prototype development is in preparation.
