ABSTRACT:
Double walled tube assemblies to meet local code requirements for heat exchangers passing potable water therethrough in non-contacting heat exchange relation for example refrigerant to liquid heat exchangers for reclaiming heat from refrigeration cycles and systems have a first or outer tubular member for passing a first fluid such as hot compressed refrigerant gas therethrough and a second or inner tubular member connected for operative relation to the first tubular member for passing the potable water to be heated therethrough. The second or inner tubular member shaped, sized, and connected to the first or outer tubular member to establish optimum heat exchange relation between the first tubular member and the second tubular member when formed into heat exchange units.
