Heat Exchangers for Solar Water Heating Systems
Solar water heating systems use three types of heat exchangers: Liquid-to-liquid A liquid-to-liquid heat exchanger uses a heat-transfer fluid (often a mixture of propylene glycol and water) that circulates through the solar collector, absorbs heat, and then flows through a heat exchanger to transfer its heat to potable water in a storage tank. Heat-transfer …
