State-of-the-Art Study of Heat Exchangers Used with Solar Assisted Domestic Hot Water Systems (Potential Contamination of Potable Water Supply).

摘要

The report presents the results of a non quantitative state-of-the-art with solar assisted domestic hot water systems where a heat exchanger interface exists between the potable water supply and heat transfer fluid. Emphasis is placed on the potential for contaminating the potable water supply if failures should occur. The study considers (1) characteristics of various heat exchanger types and their relative safety; (2) characteristics of heat exchanger fluids (toxicity,corrosivity,thermal properties,etc.); (3) regulatory considerations;and (4) designs of similar systems with potential for contamination.
