[Tianjin Jinzhong Ji HVAC purification equipment to recommend the star product - modular air conditioning units] new return air mixing section 1, the new return air position as designed at the ends, respectively, at the top or the left and right sides of settings, such as This is inconsistent with the sample to provide a specific open position. In return air can be fitted on the new valve, actuator with manual, electric and pneumatic three types, optionally by the user. 2, the filter section there early, in effect filter two, with a diamond-shaped bag fan coil models, four peaks bag, can also be equipped with an automatic winding type, filter wheels with high-quality non-woven polyester Concealed Horizontal fan coil, and the use of the filter quick-release mechanism, capping display and alarm device. New exhaust segment (also known as sub-style flat-top mixing section) of this paragraph cabinets has been a return valve, the valve before and after the top of the box, each with air vents and a new outlet, and with a control valve, which is: when Sometimes back fans, air conditioners for part of the return air discharge, so fresh air and a return air mixing ratio as required; when using DC system transition season, a return valve should be closed, and the new valve fully open exhaust valve. Energy recovery section for dual fan system for cross-points and exhaust air mixing with energy recovery. This segment has a return valve cabinets, top energy recovery device, it is a use of the exhaust of cold (hot) to the indirect cooling (heating) of new wind, new wind energy recovery through the plate, recyclable exhaust sensible heat about 60% of energy. At the same time, exhaust and fresh air are not in direct contact, especially for indoor air-conditioning system to exclude direct harmful gas energy recovery. When the DC system for use, should be closed once the return air valve vertical surface mounted fan coil, a highly toxic gas sites should set up a separate ventilation system, should not use that section. Middle section (maintenance section) connection and crew from the transition period in this paragraph internal overhaul lighting. Before filtration segment fan coil, cold front table section, heating section, muffler section shall be located in the middle section of secondary air purification segment [Tianjin Jinzhong Ji HVAC Equipment Co., Ltd. to recommend the star product - fresh air ventilator ] fresh air ventilator 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, common units: Pa. ③ Noise: Common Unit: dB (A). ④ Power: determines the size of the power consumption of the unit: 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. Fan coil installation, fan coil units, Tianjin Jinzhong Ji factory outlets provided by the Tianjin Jinzhong Ji HVAC purification equipment.
