Abstract

The aim of the project was to connect high performance solar collectors to an ammonia - water cooling system and to determine the collector efficiencies and system efficiencies in real operation. Due to technical problems with the ammonia cooling system in Egypt, the planned procedure was applied to the collector tests and for the system test it was changed in favour of a semi- empirical evaluation of two cooling systems working with normal and selective flat plate collectors. An air conditioning system with a lithium bromide - water cooling machine for the Dornier solar test house in Immenstaad and a cold storage system with an ammonia - water cooling machine in Cairo/Egypt were analyzed by a computer simulation. The test systems are described briefly. The results of the collector tests showed a considerable improvement of performance by the use of selective coatings. The performance of the cooling systems in terms of the daily cooling energy correspondingly increased, depending on the ambient conditions. The results are useful for the design of most effective solar cooling systems.
