System and method for measuring a leakage area for constructing a smoke-ventilation apparatus

摘要

Disclosed are a method and system for measuring leakage area for construction of smoke control equipment. The invention provides a system for measuring a leakage area of a test room that can include: a chamber positioned in the test room and storing air compressed by a compressor; one or more pressure sensors configured to measure a pressure change of the test room when the compressed air in the chamber is discharged instantaneously; and a gauging means configured to measure an effective leakage area in the test room by using a pressure change value of the test room detected by the one or more pressure sensors. Embodiments of the invention can enable an accurate measurement of leakage area at low cost.

1. A system for estimating a leakage area of a test room, the system comprising:
a chamber positioned in the test room and storing air compressed by a compressor; one or more pressure sensors configured to measure a pressure change of the test room when the compressed air in the chamber is discharged instantaneously; and a gauging means configured to estimate a leakage area in the test room by using a pressure change value of the test room detected by the one or more pressure sensors, wherein the gauging means is further configured to estimate a first leakage area by integrating a pressure change of the test room over an entire duration of pressure change of the test room resulting from the discharge of the compressed air of the chamber, and the gauging means is further configured to estimate a second leakage area of the test room by using a predefined correlation formula and the first leakage area.
