The fresh air ventilator is an air purification equipment, purification and heat exchange process, keep indoor air fresh, smooth, fresh air ventilator is an energy efficient ventilation through the exchange of indoor and outdoor air into the indoor air products. That fresh air ventilator indoor ventilation, our new air exchanger principle to analyze the ventilation function of the fresh air ventilator.
Fresh air ventilation machine theory
The fresh air ventilator core device is the total heat exchanger, the indoor discharge of polluted air and the outdoors into the fresh air is exchanged through the heat transfer plate temperature, at the same time by the board micropore exchange of humidity, so as to achieve both ventilation keep the indoor temperature, the stabilizing effect of humidity, which is the heat exchange process. When the total heat exchanger running in the summer cooling period, the cold fresh air from the exhaust, so that the temperature decreases, while the exhaust drying, so that the new lower air humidity; run in the winter, the fresh air from the exhaust heat, so that temperature, while the exhaust air humidification.
Fresh air ventilator structure
Ventilators by the new wind power systems, heat exchange systems, control systems, filtration systems, noise reduction system and cabinet composed of the following, we each of the introduction of these six parts.
1, the power system
The fresh air ventilator dynamic part is a high-efficiency, lower noise fan. After filtration, purification and thermal mandatory exchange treatment, the fresh outdoor air into the interior, while the indoor harmful gas filtration, purification and heat exchange processing is mandatory exhausted to the outside.
2, the heat exchange system
At present, whether in domestic or foreign, heat exchangers used in the fresh air ventilation on the stationary and rotating in two forms which the rotary heat exchanger is a rotary type. Departure from normal use and maintenance point of view, static is better than a rotary, but greater than 2 × 10000m3 / h, the mainframe, the general can only rely on the rotary heat exchanger can be achieved, it can be said stationary and rotating advantages and disadvantages.
3, the control system
(1) fresh air ventilators selection of reliable electrical components in a safe and reliable longevity run different air flow control.
(2) can be achieved automatically, timing, preset.
â'¢ optional depending on the use of different control methods.
4, the filtration system
Filtration of fresh air ventilator system is divided into the early effect of, in effect, sub-efficient and efficient four kinds of filters. Ventilators were set in both the inlet of the air filter can effectively filter dust particles, fibers and other impurities in the air, effectively blocking the outdoor air, dust and other impurities into the room to purify the purpose and to ensure that the heat of the host switching components are dirt attached to affect device performance.
5, the noise reduction system
The fresh air ventilator inside the host shell paste the polyethylene foam material, sheet metal junction long-term sealing material, which can effectively reduce the noise of the machine.
6, shell
The fresh air ventilator enclosure cabinet structure, respectively, using the cold plate is sprayed with plastic, stainless steel plates of different materials, processing of different materials can also be selected according to the actual needs of users.
Growing building closed, many people are behind closed doors and windows open air-conditioning, which leads to a lot of harmful gases have long remained in the room can not be excluded, and the passage of time will breed a lot of bacteria, affect their health and work efficiency, in order to better solve this problem, we must use the fresh air ventilator to improve indoor air quality can be seen that the new principle of air ventilator fresh air ventilator can not only quick replacement of indoor air also can be the total heat exchange to save the building energy consumption.
