Summary

The use of thermal solar energy systems in combination with thermal driven sorption chillers for climatisation gains increasing influence. For solar assisted cooling a backup system is necessary for times when no solar energy is available. Absorption chillers driven by a combination of thermal collectors and conventional furnaces, which supply the driving heat in times of no insolation, suffer from an abrupt drop of the system efficienty (COP) during the operation change. This drop in COP can be avoided by installing a combined heat buffer and storage feature. Various possibilities of heat storage features are compared. An experimental setup of a high-efficient absorption chiller which facilitates the supply of a constant load of coldness at constantly high COP in spite of periodically available driving heat is presented.
