IMPACT OF EXCHANGER LEAKAGE ON THE EFFICIENCY AND RECOVERED HEAT OUTPUT

Original language description

The article is devoted to the leakage determination on a prototype of a capillary heat pipe heat exchanger installed in the stall for pig farming. As leakage allowing mixing of air streams is undesirable, many recuperative heat exchangers bear this construction lack. The impacts of leakage on the ratios of volume flows of exhausted and fresh air, the effectiveness of heat gained from the exhausted air, the recovered heat output, and other heat flows in the exchanger are analyzed based on mass and heat balance of the exchanger. Evaluation of analysis based on measured data display significant influence of the exhausted air mixed into the fresh outside air. This causes incredible efficiency increase that is purchased of fresh air quality degradation.
