| Abstract: | The experiment on the ventilation heat exchanger designed and developed by author which was used as energy recovery from air conditioning system was performed. The effect of the indoor and outdoor temperature differences of the air conditioning room and various frontal air velocities on the performance of heat exchanging and the resistance character of the heat exchanger was investigated and the rule relations of the performance of heat exchanging and the resistance character of the heat exchanger was fitted. Then analyzed the energy conservation effect based on winter data. The results show that the effect of heat exchanging reaches 64.5% .And the effect of energy conservation is so obvious. |
