Název v původním jazyce

Analysis of impact of plate air-to-air recovery untightness on its thermal and mass balance

Popis výsledku v původním jazyce

The article deals with the issue of determination of leaks from a recovery heat exchanger using secondary heat contained in ventilation air and an analysis of impact of leak upon the nature of ventilation system, shared thermal flows, thermal and operational efficiency of the exchanger. The verification of the hypothesis based on results of a theoretical analysis of the issue was accomplished at an operational metering of a prototype of ventilation unit provided with a plate exchanger in calf breeding house after the installation of the unit and, furthermore, after 9 months of the operation of the unit. Results of the verification confirmed the conclusions of the theoretical analysis of the issue. They demonstrated that the new unit added 21.1 to 30.8%of extracted air to the atmospheric air supplied to the breeding house. Heat output exchanged during process of fresh air contamination varied between 5.15 to 11.42 kW.
