Compulsory Policies of Installing Solar Water Heating Systems and Normative Construction Procedure in China

摘要

In recent years many local governments in China have implemented compulsory policies of installing solarrnwater heating systems integrated in new buildings. So system quality and capacity becomes a very importantrnproblem. Therefore a complete supervision system for quality control to solar water heating systemsrnintegrated in buildings during whole construction procedure has been formed gradually in China. Thisrnsystem includes technical code for design and acceptance, performance requirement to products of solarrncollectors and a normative construction procedure etc.rnIn this paper it is given the background of compulsory policies of installing solar water heating systemsrnintegrated in new buildings and introduced a normative construction procedure for solar water heatingrnsystem. The procedure runs through design, product selecting, construction, acceptance and evaluation. Asrnmost of buildings are tall buildings in China’s cities some installation types for solar collector integrated inrnbuildings and better operation measures for central solar water heating systems to suitable special conditionrnof China are also given in the paper.
