Wei, a variety of central air-purifying agent can safely and quickly benefit 1. sterilization mildew central air-conditioning air purification parameters, reducing indoor air dust, eliminate musty, eliminate indoor air quality problems resulting from discomfort and harm to the human body improve work efficiency and quality of life. 2. it can effectively increase the capacity of the central air-conditioning ventilation air purifiers Which is good, improve heat transfer efficiency energy saving systems. 3. maintenance of the air conditioning system can effectively prolong the service life of air conditioning, reducing air-conditioning system operating costs. 4. Clear the ventilation duct of combustible dust, eliminate safety hazards 1. The five-star hotel, for example, if a central air conditioning needs cleaning more than two hundred thousand yuan. Under the Ministry of Health, should do a two-year health evaluation, evaluation unqualified, it must be cleaned to reduce the burden Hotel 2. Engineering and other departments, specifically to reduce manpower investment in the hotel central air conditioning cleaning, control sales 3. Reduce the cost of rooms and public areas in the breeding of germs and dust deposition central air-conditioning air purification, to hotel guests and staff to bring a comfortable environment, but also reduce the workload of room attendants Wei a central air purifier VBK- H return air type air cleaner device back to the wind air purification systems Description: domestic and international leading technology the perfect combination of the four semiconductor ionizer + / semiconductor catalyst / wave reactor / semiconductor ionizer - Pre coarse filter to prevent small animals and large particles into the air conditioning, use "Photocatalytic" and semiconductor ionizer original and "specular light" technology, so that particles in the air under the action of bacteria in the semiconductor positive ionization device charged, bacterial suffered electrical breakdown (lightning ) effect particles in the air will be adsorbed on the semiconductor bacteria ionizer dust collection plate, resulting in cell death electrical injury; at the same time, by the effect of light wave mirror reaction apparatus, a semiconductor catalyst obtained ev energy (electric power), semiconductor catalytic transition to the conduction band and valence band, birth trauma electron - hole to form negative oxygen ions (O2-) and radical (OH) Central air-conditioning air purification performance, accelerated oxidation, decomposition of harmful gases to achieve catalytic effect semiconductor; purification then through the semiconductor negative air ionizer, and an excess of positive ions and dust again, to 0.5 micron removal efficiency of ≥99%, PM2.5 microns completely removed. Post-activated carbon fiber filter, whose role is to remove contaminants semiconductor Farm is not divisible
