This European Standard specifies methods to be used for laboratory testing of air-to-air heat recovery devices or those recovering heat from flue gases of heating appliances in buildings (except process-process applications) to obtain rating data . It gives test requirements and procedures for performing such tests and specifies input criteria required for tests to verify performance data given by the manufacturer. For the purposes of this standard, the tenn exhaust air may also be taken to mean the products of combustion. This European Standard is intended to be used as a basis for testing heat recovery devices for HVAC-systems, which as specified in prEN 247 consist of the heat exchanger itself installed in a casing having the necessary air duct connecting elements and in some cases the fans and Pumps, but without any additional components of the HVAC-system. This European Standard is applicable to the following categories of heat exchangers: Category I Recuperators Category I1 With intermediary heat transfer medium Category IIa - without phase-change Category IIb - with phase-change (heat pipe,. .) Category 111 Regenerators (containing accumulating mass) Category I1 la - non hygroscopic Category IIlb - hygroscopic Heat recovery devices with exchangers and intermediary heat transfer medium without phasechange (category IIa) are to be tested as one unit including pump and pipe system between the coils.
