Approved by the state commission, the newly established National Indoor interior environment and environmentally friendly products Quality Supervision and Inspection Center has officially work, and published the first national indoor environment and interior environment, industry trends report. Two methods to detect air pollution According to the National Indoor interior environment and environmental products quality inspection center's Director Song Guangsheng, in March this year, the national indoor air quality standards promulgated 10th anniversary and national passenger cars and Air Quality Assessment Guidelines promulgated and implemented the first anniversary, after a more than a year of preparation, under the leadership and guidance of the national environmental quality control departments, on the basis of the former State indoor environment and indoor environmental quality supervision and inspection center, formally approved the establishment of China's first professional indoor interior environment national test center for quality inspection test. The quality inspection center for indoor and interior of the NPC and the attention of the community environmental pollution problems, released its first national indoor environment in the vehicle industry trends report, also released "indoor air purifiers PM2.5 test "technical specifications and volatile organic compounds of automotive interior parts testing and evaluation approaches. Song Guangsheng said that the implementation of China's 10 years ago, "indoor air quality standards have been specified respirable particulate matter (PM10) daily averages of 150μg/m3, estimated PM2.5 daily average concentration of up to about 80μg/m3. According to the conditions in China in 2012 released "Ambient Air Quality Standard GB3095-2012, the Ministry of Environmental Protection provides ambient air concentration of PM2.5 control a standard daily average concentration of 35μg/m3, with the World Health Organization recommended PM2. The 5 daily average concentration of 25μg/m3 standard similar PM2.5 test evaluation criteria can be used as indoor and in-car environment. Air purifier purification effect According to tests, the air purifier with a high efficiency filter function can effectively purify the indoor and in-car environment PM2.5 pollution. Song Guangsheng said, HEPA dust filters can purify the 0.3μg of particulate matter, purification efficiency can reach 99.9%. If the air purifier installed ultra-high efficiency filter media, the removal efficiency of 99.999%, can effectively reduce the health impacts of PM2.5 pollution in the air. Therefore, in the case of atmospheric pollution issues within a short period of time is difficult to solve, the quality inspection center experts are of the opinion that the use of air purifier is one of the most effective method of purifying indoor and vehicle pollution. Air purifier to remove particulate matter PM2.5 technical specification of test methods developed by the National Indoor interior environment and environmental products quality inspection center organized experts to air purifiers ability to remove PM2.5 parameters as the performance index, the use of "clean air" , m3 / h. This method is suitable for indoor, car, cabin and aircraft air purifier to remove air PM2.5 in the determination of the amount of clean air. Specification requirements, the air purifier to remove airborne particles PM2.5 clean air measured value shall not be less than 90% of the nominal value. The purification efficiency of the air purifier to remove airborne particles PM2.5 should be not less than 50%. Three aspects of governance vehicle pollution Environmental pollution problems for the existing car, Song Guangsheng, mainly around the three aspects of the work. The first is how to control the vehicle air pollution, especially air pollution problems of the new car. New car pollution problems have attracted the attention of the whole society. The last two sessions, Geely chairman Li Shufu has proposed a special motion this year, car and atmospheric air quality problems. Solve new interior air quality problem has become one of the main problems of automotive enterprises to improve the quality of the car, the national indoor environment and indoor environmental products quality inspection center inside the air quality testing laboratory to become China's first car with a national certification and accreditation air quality testing laboratory, will be engaged in this work. Second is to control the pollution problems of the automotive interior parts. According to Song Guangsheng, the National Indoor interior environment and environmentally friendly products quality inspection center on the widely solicited opinions basis, to develop the automotive interior parts VOC test method technical specifications, as well as automotive and automotive interior parts enterprises to carry out car The interior pieces VOC testing, have created favorable conditions so as to improve the quality of air inside the vehicle. In addition, Song Guangsheng, in the atmospheric environment the haze pollution problems within a short time is difficult to solve the case, how to design car air-conditioning systems and air purification system to ensure that the conditions of air pollution, air quality inside Safety and Health, which is trying to solve the problem of the auto companies and interior environmental protection enterprises. At present, the National Indoor interior environment and environmentally friendly products quality inspection center is organizing experts to the development and promotion of technologies and products.

Manifold, the inner diameter of the catchment should not be less than the total for the return pipe diameter, and the manifold, the largest section of the catchment flow rate should not be greater than 0.8m / s. Each watershed, water catchment the branch loop should not be more than 8. Loop too much will lead to sub-catchment of the pipeline is too dense, is not conducive to the installation. Each branch loop supply and return pipes should be set off valve brass ball valve. 2, the water supply connection pipe before the watershed, the direction of flow should be installed valves, filters and drain pipe. Set in the manifold before the two valves, for cleaning filters and replace or repair the heat metering devices off when use; set the dust filter to prevent clogging the flow meter and heating pipe. Valves and filters in front of the heat metering devices, can also be used to dust filters the ball valve (filter and ball combination as a whole) alternative. In the catchment backwater connecting pipe, drain pipe should be installed and the installation of balancing valve or other valve off mediation. System accessories should be corrosion-resistant materials. Install drain devices, used to flush the pipeline and discharge with pre-acceptance and maintenance and repair, it is best to nearest floor drain drainage discharge device. System with heat metering requirements should be set to heat metering devices. 3, the in total trap into the water catchment outlet pipe, should be set to the bypass pipe, valve set on the bypass pipe. The bypass pipe connection location should be at the beginning of total inlet pipe (valve) and before the end of the outlet pipe (valve) to ensure that heating piping system flushing water does not flow into the heating tube. 4, watershed, catchment shall be set to manual or automatic exhaust valve. Try to install an automatic air release valve, so that after the use of the process to the user convenience, to avoid the hot and cold pressure difference and the replenishment of the gas gathering, leaving the system operation is blocked.
