Test Procedure for Accelerating Aging of Solar Thermal Collectors
Abstract
Based on the experience and data gained during a 3 year exposure of different solar thermal collectors under different climate conditions (tropical, arid, arid maritime, moderate and cold alpine) and system simulations using TRNSYS a test procedure for accelerating aging of solar thermal collectors has been developed and exemplary conducted on flat plate collectors. The overall test procedure which comprises a UV resistance test, a salt mist test, a humidity test, a temperature cycle test and an extended high temperature test is introduced and described in detail. Key-words: collector test, accelerated aging test, lifetime prediction
