Résumé

The use of waste heat of distributed cogeneration plants for thermal driven refrigeration systems can improve the annual utilization ratio significantly. This results in so called trigeneration plants. The use of thermal energy at temperatures from a minimum of 65°C to 90°C or more is a typical application for systems using water and lithium bromide solution as working fluid. With this kind of sorption refrigeration systems it is possible to provide cooling at temperatures close to but not below 0°C. Here a newly designed resorption refrigeration system based on NH3/H2O is introduced. Compared to a conventional absorption cycle with a condenser and an evaporator this resorption system consists basically of two solution absorption cycles. The new designed refrigeration system with ammonia and water as the working fluid is able to provide cooling temperatures below 0°C by using waste heat at temperatures in the range of 65°C to 90°C. An attached ice storage system is able to retain the cooling capacity. Thus allows the temporarily decoupling of the cooling demand from the generated thermal capacity. The application of plate heat exchangers together with the low pressure level of the resorption process makes it possible to design compact and cost effective plants.
