[Tianjin Jinzhong Ji HVAC purification equipment to recommend the star product - fresh air ventilator] Why use a new wind ventilators construction, hazardous substances decoration, furniture, decoration and office equipment is a major cause of the release of indoor pollution . Plus summer and winter people rely more on air conditioning cooling and indoor fan coil heating, indoor ventilation is poor, indoor harmful gas is not released and the replacement of harmful gases continue to accumulate, increasing the concentration of continuous horizontal concealed fan coil tube, resulting in deterioration of indoor air quality, people feel sleepy, fatigue, chest tightness, susceptible to disease, reduced efficiency, which is the World Health Organization named the "sick building syndrome" also known as "Air conditioning disease" root causes of these difficulties is not enough fresh air. Use fresh air ventilator replace indoor air, keep indoor air clean, can solve these problems. Therefore, the new wind ventilators is also a "health" products. [Tianjin Jinzhong Ji HVAC purification equipment to recommend the star product - air handling units] air handling units generally use double wall color powder-coated steel or cold rolled steel (bottom inside of the plate, some made of stainless steel), insulation materials are mostly middle or flame retardant polyurethane foam centrifugal glass wool. If a single thermal conductivity, water absorption and density of view, both of which are good insulation material. However, due to the air handling unit during operation, sending back high speed blower fan coil models, cabinet vibration is relatively large, and light weight glass wool, there are large gaps in the structure vulnerable to long-term vibration and fall off, resulting in thermal coefficient increases sharply, losing the role of air-conditioning fan coil insulation, causing condensation wall air handling units, so the supply air temperature is high. But not necessarily using polyurethane foam insulation has good effects, such as poor quality polyurethane foam insulation will affect the results. Therefore, when selecting air handling units, can not lightly choose wall insulation. _ Tianjin Jinzhong Ji fan coil installation Alibaba Gold Supplier _ Tianjin Tianjin Jinzhong Ji fan coil provided by HVAC purification equipment.
