The residual pressure monitoring system, also known as the residual pressure measurement and control system, differential pressure measurement and control system, or intelligent residual pressure monitoring system, is a systematic monitoring device used in the positive pressure air supply system of high-rise buildings to regulate the residual pressure value in the fire front room or stairwell. This system includes a residual pressure monitoring system host, residual pressure detector, residual pressure controller, gas pipe, gas pipe end, bypass valve (electric multi blade open regulating valve/electric actuator), etc
Air quality testing refers to the detection of the quality of air. The quality of air reflects the concentration of pollutants in the air. Air pollution is a complex phenomenon, and the concentration of air pollutants is influenced by many factors at specific times and locations. The size of anthropogenic pollutant emissions from fixed and mobile sources is one of the main factors affecting air quality, including vehicle exhaust, industrial emissions, residential and heating, and waste incineration. The development density, topography, and meteorology of cities are also important factors affecting air quality
All equipment components meet and exceed the functional requirements of relevant national standards such as GB51251 Technical Standards for Building Smoke Control and Exhaust Systems, GB50016 Code for Fire Protection Design of Buildings, and GB50098 Code for Fire Protection Design of Civil Air Defense Engineering
