"Rotary Heat Exchanger Efficiency Influenced by Air Tightness"@en . . "Thermal effectiveness of rotary heat exchangers is dependent on pressure differences on face surfaces of the rotor. The air passes of extracted indoor and supply outdoor air flows are seperated by perimetral and radial tighteningstrips on the rotor surface, which are not perfect tight. Penetration of air flow (leakage) through those untightness are connected with transfer of contaminants and by the heat, which influents the effectiveness of heat recovery. In the article are derived the pressure differences, dependence of leakage air flow value on pressure differences, after laboratory and in the field measurements. Discussed are the problems with application of standard EN 308/1998 for testing and rating of heat exchangers and the opportunity for it's improvements."@en . . "80-02-01811-7" . "21220" .
