Résumé

A solar powered cooling machine with no moving parts has been built for demonstration purposes at the Institut für Thermodynamik und Wärmetechnik, Germany. The main part of the device is an absorber/desorber unit which is mounted inside a concentrating solar collector. The heat of absorption is transported out of the solar collector by means of two horizontally working heat pipes. The working pair consists of ammonia used as the refrigerant and strontium chloride as the absorbing medium. The performance of the solar refrigeration unit was measured in a field test. The working principle of a discontinuously working, solid sorption cooling machine is explained using the demonstration machine as an example. Results obtained from a field test performed in 1995 are presented and discussed. Furthermore, a simulation program for the numerical simulation of a solar powered solid sorption cooling machine has been developed and tested. Finally, to confirm a problem-free continuous operation of a solid sorption system, a long term study over 14 months was carried out using ammonia-strontium chloride as the working pair.
