Heat recovery fresh air ventilation unit with heat recovery fresh air ventilation machine equipment on the indoor air can be mixed, filtered, cooling, heating, etc. handle different functions. Secondary use of the indoor energy returned by the device in the desired location, to the energy, saving role. Specific configuration is as follows: 1, Box construction (frame and insulation plate) 1.1, box fresh air ventilation with heat recovery unit according to the functional segments for production. Easy field installation. 1.2, the unit box with removable structure, framework aluminum frame. 1.3, insulation shield the inner wall plate with a thickness of less than 0.5 mm galvanized steel sheet; and an outer wall plate with a thickness of not less than 0.5 mm of color plate, the surface at the factory insulation sheeting covered with a protective film to prevent the site Assembled surface is scratched. Insulation shield interlayer insulation material forming a rigid polyurethane foam insulation. Cabinet insulation thickness of not less than 25 mm for all models. 1.4, the cabinet frame, insulation shield with anti-cold (hot) bridge measures to reduce heat loss and avoid outer surface condensation. Unit requires anti-cold bridge coefficient reached the national standard. 1.5, between the insulation shield and the frame of the unit, between the various functional segments when assembled, high reliability sealing measures, Heze City, the new wind ventilators to ensure sealing of the entire unit. Box leakage rate of the national standard. 1.6, housing units have sufficient strength, in transport and launch, will not be allowed to run and when deformation phenomena bump stop. 1.7, within the unit surface flat, smooth, non-fouling corner. Nice outdoor unit surface, the outer surface no scratches, rust and indentation, surface finish, spray coating uniformity, color consistency, no flow marks, bubbles and peeling. 1.8, the bottom of the channel units are to facilitate mounting pad. Channel surface galvanized embalmed. All double insulation panels (including roof, wall, door repair, etc.) are removable without affecting the independent structural framework. Total heat efficient filter type 1, the early effect filter filtered outdoor large particles of dust, insects 2, the electronic dust chamber can be washed repeatedly, ventilators, long life, Linyi City, the new wind ventilators, low maintenance cost 3, high efficiency filter PM2.5 dust and other harmful substances, effectively purify the air 4, activated carbon filters planktonic bacteria in indoor air, absorb harmful gases 5,24 hours of continuous indoor ventilation, for your family comfort, ease of living space 6, built-in cancellation ## more beautiful, more muted Linyi new wind ventilators ventilators _ _ the total heat exchanger by wucheng Dingrui Air Conditioning Equipment Co., Ltd.
