공조기를 이용한 가압테스트를 통한 외피 기밀도 실측

Abstract

This research is a case study performing the air-andler fan pressurization test in a real building. The test has been performed follwing an exiting test method(i.e. CGSB 149.15-96 Standrard). The test building is a 5-story office with a square (32.4m × 32.4m) footprint built in 2001 at Dae-jeon. The test building gas four air-handling units, but the unit located at the basement was out of order. Consequently, the 3 air-handling units installed at the 1st floor and 5th floor were used to pressurize the building. To measure the whole building envelope air leakage, the SA airflow rates in each air handler, operated at the 100% outdoor air mode with closed return and exhaust air dampers, were monitored together with the building pressure. This paper provides some practical information acquired in the field measurement of envelope leakage using the established air-handler fan pressurization test method.
