风管系统安装后不按规定作漏光、漏风检查和试验
After the installation of the air duct system, the light and air leakage inspection and test are not conducted according to the regulations
漏光或漏风量测定是对通风空调施工质量的一项检验措施，必须严格按要求规范进行检验，若风管系统安装后不按规定作漏光、漏风检查和试验，可能会造成系统大量漏风，使整个系统和项目工程达不到使用要求，增加不必要的返工和浪费，同时也浪费了能源。
The measurement of light leakage or air leakage is an inspection measure for the construction quality of ventilation and air conditioning, which must be inspected in strict accordance with the requirements and specifications. If the air duct system is not inspected and tested according to the regulations after installation, it may cause a large amount of air leakage in the system, make the whole system and project project fail to meet the use requirements, increase unnecessary rework and waste, and waste energy at the same time
