Verification of the Effects of the Secondary Heat Recovery from Ventilation Air in an Animal House for the Fattening of Broiler Chickens

Result description

The calculation of the thermal balance of the animal house documents that the power management system that includes a heat recovery exchanger unit may reduce the thermal capacity of external sources of heat in the animal house by 26.5% even when subjectto extreme conditions and at the atmospheric temperature of -12 °C and the age of chickens being 1 day. The results of the metering and calculations of the efficiency have proven that the heat exchanger reaches the operational efficiency of 10 - 47% andthermal efficiency of 20 - 80 % even during the most demanding operational first twenty days of the breeding cycle of broiler chickens. The specific consumption of energy for space heating and ventilation related to 1 kg of the live weight of chicken inthe animal house facility A provided with a heat recovery exchanger unit at the average atmospheric temperature during the cycle being 4.3 °C amounted to 278.5 Wh.

    VERIFIKACE VLIVU VYUŽITÍ DRUHOTNÉHO TEPLA VĚTRACÍHO VZDUCHU VE STÁJI PRO VÝKRM BROJLEROVÝCH KUŘATA

  • Czech description

    Výpočet tepelné bilance stáje dokladuje, že i v extrémních podmínkách při venkovní teplotě -12°C a stáří kuřat 1 den sníží energetický systém s rekuperačním výměníkem tepelný výkon externích zdrojů tepelné energie ve stáji o 26.5 %. Výsledky měření a výpočtů účinností ukázaly, že i v provozně nejnáročnějších prvních 20 dnech chovu brojlerových kuřat dosahuje výměník provozní účinnosti 10 - 47% a termické účinnosti 20 - 80%. Měrná spotřeba energie pro vytápění a větrání vztažená na 1 kg živé hmotnosti kuřete ve stáji A s rekuperačními výměníky, při průměrné teplotě venkovního vzduchu v turnusu 4.3°C, činila 275.8 Wh.
