[Tianjin Jinzhong Ji HVAC purification equipment to recommend the star product - fresh air ventilator] choice points 1. The new wind ventilators for the room with a small ventilation with heat recovery equipment. The main control parameters for the selection of air flow, static pressure loss, the outlet total pressure, input power, effective ventilation rate, exchange efficiency, noise and the like. 2. The new wind ventilators performance should meet the requirements of Table 1, the device corresponds to the nominal air flow heat exchange efficiency value of not less than the requirements in Table 2. 3. In general, when a new air temperature of about -10 ℃, the exhaust side frost may occur, can be set up in front of the air preheater unit. 4. The device should be chosen to meet the relevant requirements of other standards and specifications. [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 air handling units in operation, sent back to the fan at high speed fan coil thermostat, cabinet vibration is relatively large, and the quality of light wool fan coil works, the structure is easy because there is a large gap between the long-term vibration and fall off the fan coil prices, leading to a sharp increase in thermal conductivity, loss of insulation effect, 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.
