[Tianjin Jinzhong Ji HVAC purification equipment to recommend the star product - fresh air ventilator] new wind ventilators main technical parameters: ①-way ventilation: it determines the size of the ventilation or air changes, Common units: m3 / h. Ceiling fresh air ventilator unit ② residual pressure: its size determines the distance to overcome the resistance of the air, or the ability to fan coil models, common units: Pa. ③ Noise: Common Unit: dB (A). ④ Power: determines the power consumption of the size of the horizontal concealed fan coil units: W or kW. ⑤ heat transfer efficiency: the ratio of the reaction heat recovery unit or efficiency, unit:%. ⑥ structural parameters: the dimensions and installation / fitting dimensions, it is subject to restrictions on the installation conditions. [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 fan coil during operation, sending back the fan at high speed, large cabinet vibration, and light weight glass wool, there are large gaps in the structure vulnerable to long-term vibration and fall off, resulting in thermal conductivity increases sharply, losing insulation effect cassette fan coil units, air handling units siding causing condensation, 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. Air conditioning fan coil units, fan coil Tianjin, Tianjin Jinzhong Ji fan coil manufacturers supplied by Tianjin Jinzhong Ji HVAC purification equipment.
