KANATÇIKLI ÇAPRAZ AKIŞLI ISI GERİ KAZANIM VANTİLATÖRÜNDE ISI TRANSFERİ

Bu çalışmada, bir ısı geri kazanım sistemi tasarlandı ve imal edildi. Deneysel işlem egzoz ve taze hava sıcaklıklarının ölçümlerinden oluşmaktadır. Elde edilen sonuçlara göre ısı geri kazanım ventilatörünün etkenliği hesaplandı ve tartışıldı. Bu deneysel çalışmadan toplanan egzoz ve taze hava akışının çıkış sıcaklık verileri ve HRV nin etkenliği birçok giriş akış şartları için hesaplandı. İlave olarak etkenliğin ısı geri kazanım sisteminin NTU değeri ile değişimi hesaplandı.

HEAT TRANSFER IN A CROSS-FLOW HEAT RECOVERY VENTILATOR WITH FIN

In this study, a heat recovery ventilator was designed and constructed. Experimental procedure consisted of measuring of supply and exhaust air outlet temperatures. According to the results obtained, the effectiveness of heat recovery ventilator (HRV) was calculated and discussed. From the data including supply and exhaust air outlet temperatures obtained from this experimental work, the effectiveness of HRV was calculated for the several inlet flow conditions. In addition, variation of effectiveness ( ε ) with the number of transfer units (NTU) of heat recovery unit was calculated

Keywords:

Heat recovery , Ventilation, Cross flow, Heat recovery ventilator (HRV),
