DETERMINING AIR LEAKAGE |
| 摘要 |
A system (100) and method for determining the air leakage of a space (102) in a building is disclosed. The system (100) comprises a processor (120); a source (130) of compressed air; a pressure sensor (150) configured to measure the pressure of air residing within the space (130) and to provide background pressure signals to the processor (120); a nozzle unit (140) for metering the supply of a pulse of compressed air from the source (130) and for directing the pulse into the space (102) and a source pressure sensor (132) configured to measure a transient pressure during the pulse and to provide a transient pressure signal to the processor (120), wherein the processor (120) is configured to determine the air leakage based on changes in the background pressure signals and from the transient pressure signal. This provides a more reliable and cost effective way of measuring air leakage. |

1. A system for determining the air leakage of a space in a building, said system comprising:
a processor; a source of compressed air; a pressure sensor configured to measure the pressure of air residing within the space and to provide background pressure signals to the processor; a nozzle unit for metering the supply of a pulse of compressed air from the source and for directing the pulse into the space; and a source pressure sensor configured to measure a transient pressure during the pulse and to provide a transient pressure signal to the processor, wherein the processor is configured to determine the air leakage based on changes in the background pressure signals and from the transient pressure signal. |
