Supply and use of heat recovery ventilation system increase steadily as effective energy conservation equipment. Heat recovery ventilation system can be installed at ceiling of balcony or emergency space. However, in case of fire, because emergency space have to remain as empty space by law, ventilation system can not be installed at emergency space. Therefore the need of proper installation space of ventilation system is embossed. In this study, to install heat recovery ventilation system in light weight wall, thickness of heat exchanger was assembled below 140㎜. And efficiency of heat recovery was analyzed through performance experiment on case of cooling and heating about ventilator that a total heat exchanger and two total heat exchanger was connected in series.

Exhaust heat recovery ventilation systems conserve energy through enthalpy recovery between air intake and exhaust, and they are being increasingly used. An exhaust heat recovery ventilation system can be installed in the ceiling of a balcony or emergency evacuation space. However, in the case of fire, the emergency evacuation space has to by law remain as empty space, and therefore, a ventilation system can’t be installed in an emergency evacuation space. Therefore, the need for a proper installation space for a ventilation system is emphasized. In this study, to install a heat recovery ventilation system in a lightweight wall, a heat exchanger was assembled of thickness below 140 mm. The efficiency of heat recovery was analyzed through performance experiment, in the case of the cooling and heating mode. The heat recovery efficiency increases when the surface area is increased, by using closer channel spacing in the heat exchanger, or by increasing the size of the heat exchanger.

The supply and use of exhaust heat recovery ventilation system as effective energy saving equipment has been increasing steadily. The exhaust heat recovery ventilation system can be installed at ceiling of balcony or emergency space. However, ventilation system can not be installed at emergency space because where have to remain as empty space by law. Therefore, the proper installation space of ventilation system is needed. In this study, to install heat recovery ventilation system in the light weight wall, thickness of heat exchanger was assembled below 140 mm. One or two paper heat exchangers were installed in the ventilation system. The efficiency of heat recovery was analyzed through performance experiment on case of cooling and heating mode.

Therefore the need of proper installation space of ventilator is embossed. In this study, to install heat recovery ventilator in light weight wall, thickness of heat exchanger was assembled below 150 ㎜. And efficiency of heat recovery was analyzed through performance experiment on case of air conditioning and heating about ventilator that a heat exchanger and two heat exchanger was connected in series.

우리나라 공동주택은 10층, 일반 건축물은 11층 이상의 경우 전층에 대해 제연설비를 설치해야 하며 대부분 부속실이 있는 특별피난계단이 설치되고, 이 부속실을 비상용 엘리베이터의 승강장으로 겸용하고 있는 구조이다. 그런데, 기존 급기가압 제연시스템의 제연댐퍼는 방화문의 위치에 따라 방연풍속을 확보하지 못하고 강력한 와류에 의해 오히려 화재를 확산시키는 경향의 유동을 발생시키는 경우도 있다. 본 연구에서는 기존 제연댐퍼의 위치에 따라 방연풍속을 제대로 학보하지 못하는 단점을 보완하여 위치에 상관없이 방연풍속을 100% 확보하고, 그 구조를 단순화하여 원가를 절감할 수 있는 급기가압 제연성능 향상을 위한 무지향성 급기가압 제연댐퍼를 개발하였다.
