EVR evaporation of fresh air ventilator features: ▉ high recovery efficiency at the design stage unit heat exchanger total heat fresh air ventilator, using a high NTU (heat units) coefficients are designed to have a higher heat transfer efficiency and it uses a patented technology to achieve a higher efficiency level. Its summer temperature efficiency of 119.7%, the enthalpy efficiency of 79.11% ▉ unique sealed structure, to prevent exhaust pollution of fresh air metal core, airtight structure, ensure to eliminate the exhaust of bacteria and viruses infiltrate contamination of fresh air, to maintain the quality of fresh air. Adoption Unique point - closed surface binding process to solve the point - penetration point pollution problems exist in the process combination of water and gases through the field, completely eliminate exhaust pollution ▉ fresh air inlet and outlet vents diverse crew flexible exchange position can be used on-site, facilitate the work of design and installation .▉ quiet operation and compact design of the chassis and Structure Optimization, low-noise double-suction forward centrifugal fan; polyethylene inner wall insulation paste protective layer has good noise insulation spacer effect ▉ easy to control the electrical system uses two secondary circuit design, using a switch panel control, start fast ﹑ ﹑ ﹑ stop crew safety simple .▉ wide range of applications for general civilian air-conditioning situation, as well as some dust containing odor ﹑ ﹑ ﹑ paint composition of bacteria and viruses and other industrial applications of heat recovery fresh air ventilators Product description: XHB series heat recovery fresh air ventilation air volume: 300-5000m3 / h Pressure: 40-250Pa Features: The ceiling-mounted fresh air ventilators, ventilation and ventilation, to maximize not take the heat efficiency up to 70%, built-dust filter ceiling total heat fresh air ventilators, effectively prevent dust and debris into the interior, energy saving, low noise, reliable operation, easy maintenance Application: open office area, hall , computer rooms, classrooms, factories, shopping malls, sports arenas, PBX rooms. First, the working principle When the indoor air conditioning return air and fresh air was positively flow through the heat exchanger core cross way, since both sides of the flat baffle airflow temperature difference and the existence of water vapor pressure difference between the two streams while exhibiting heat and mass transfer phenomena , causing a total heat exchange process. This process is accomplished by flat separator, so the case of the transmission type total heat exchange phenomenon. When installed on a system-wide heat exchange new wind turbine operational during the summer, the fresh air obtained from air conditioning return air in the cold can make the temperature decreases, while being air-conditioning return air drying, the fresh air moisture content lower; run in the winter fresh air from the air conditioner return air temperature heat energy obtained while being air conditioning return air dried whole heat ventilators new wind patterns, so that the new lower air moisture content; get fresh air temperature thermal energy from the air conditioner is running in the winter when the return air, return air simultaneously humidification, so that the new air moisture content increases, so recovering energy from the air conditioner return air through the whole process of heat exchange core body heat fresh air. Total heat fresh air ventilators, new wind ventilators, ventilators supplied by wucheng Dingrui Air Conditioning Equipment Co., Wucheng Dingrui Air Conditioning Equipment Co., Ltd.
