Small-capacity water-lithium bromide absorption chiller for solar cooling and waste-heat driven cooling.

Author(s) : STORKENMAIER F., HARM M., SCHWEIGLER C., et al.

Summary

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 until now, chillers below 35 kW were not available. Following a joint European project, a prototype development of a 10 kW absorption chiller with water/lithium bromide as working fluid was initiated by a German producer and distributor of solar thermal systems. The plant uses driving hot water of usually 56 to 85 °C for solar and 80 up to 105 °C for trigeneration applications, respectively and exhibits a considerable improvement in performance compared with present plants. By means of a careful cycle design and a fully automated control an efficient part-load behaviour down to 40% load is achieved. With the aim of an optimum configuration and control of the system a transient system simulation has been carried out and operational data gathered during the start-up phase is presented. Further testing under realistic conditions with solar collectors as driving heat source are being carried out in a solar cooling installation of an office building in Berlin. A field test is under preparation.
