PERFORMANCE OF A SOLAR COOLING SYSTEM USING DIFFERENT TYPES OF EVACUATED TUBULAR COLLECTORS
For several years experiments with solar air conditioning have been carried out in the Solar Laboratory of the Joint Research Centre of the Commission of the European Communities in Ispra. Performance data have been obtained for different systems using LiBr - H-20 absorption chillers and selective flat plate collectors. This report gives a detailed description of the system which has been operated with evacuated tubular collectors (ETC) during the summer of 1982 and 1983. Three types of ETC's have been used: Sanyo STC-CU 250 L, Philips VTR 261 and Philips VTR 361. The absorption chiller used is the Arkla WF 36. The results obtained with this system during two summers are presented. The experiments showed that evacuated tubular collectors can be used for solar cooling very well. The daily efficiencies for some collectors were excellent (around 50 % for a typical day). Some durability problems were identified. However these problems do not look unresolvable and should not inhibit the development of this kind of collectors.
