First, the product profile
Fresh air ventilator is based on the side of the air in the closed side of the wind cited wind, then in the room will form a "new wind flow field" principle of the design and development. It relies on mechanical air supply, cited wind, forced in the system to form a new flow field. Is a moment to keep the indoor air clean and fresh new environmentally friendly electrical appliances. This independent indoor air replacement, purification of the circulatory system, can exclude indoor air pollution at the same time, enter the natural fresh air, the input of the new air before the first filter, sterilization, heating, oxygen and many other treatment.
Shandong Century Changlong New Energy Co., Ltd. production of fresh air ventilation by the National Air Conditioning Equipment Quality Supervision and Inspection Center test, the indicators have reached the relevant standard requirements.
1, plate fin heat exchanger picture:

 Plate-fin heat exchanger is a kind of air and air direct exchange of static heat exchanger, it does not need through the intermediate medium for heat transfer, there is no rotation system, therefore, static plate fin heat exchanger (also known as fixed Type heat exchanger) is an ideal energy recovery equipment. Static plate fin heat exchanger is in the two sides of the separator on both sides of the two air flow temperature difference and water vapor pressure difference, the sensible heat or full heat recovery.
    In the plate-fin heat exchanger, the two streams are cross-flow through the heat exchanger. The heat exchanger of the heat exchanger is non-permeable, with good thermal conductivity of the material, generally mostly aluminum material. The full heat exchanger is a permeable air-air heat exchanger in which the partition plate is made of a material which has been treated and has good heat transfer and moisture permeability characteristics. The exchange mechanism of temperature (sensible heat) is the flow of air on both sides of the medium through the different temperatures, the heat through the conduction of the way to exchange. The exchange of humidity (latent heat) in the whole heat exchanger is carried out by the following two mechanisms:
    ① through the media on both sides of the water vapor pressure difference for humidity exchange.
    (2) The water vapor on the high humidity side is absorbed by the hygroscopic agent and is released to the low side by the capillary action of the paper fiber.
3, plate fin heat recovery:
A, static heat exchanger, in order to easily arrange the air flow within the machine channel and reduce the size of the machine, small and medium-sized fresh air ventilator with a flat cross-static heat exchanger, its working principle is: cold, hot air movement Direction is perpendicular to each other, and the airflow in the heat exchanger belongs to the convective heat transfer property in the turbulent boundary layer and has high heat exchange efficiency.
B, significant heat exchangers and all-heat exchangers, sensible heat exchangers made of aluminum foil material, high temperature conductivity, long life, suitable for indoor and outdoor temperature difference between the small humidity difference. All heat exchangers are made of special fibers made of special fibers. This material has the characteristics of high moisture permeability, good air tightness, tear resistance and aging resistance. Full heat exchanger suitable for indoor and outdoor temperature difference between the small humidity difference area.
Second, the characteristics of fresh air ventilation unit:
1, two-way ventilation indoor and outdoor two-way ventilation, fresh air equivalent displacement.
2, filter processing fresh air filter processing in line with building regulations. The filter prevents dust and other contaminants from entering the room.
3, energy efficient built-in static heat exchanger, heat exchange efficiency of more than 70%, hot and cold load (room temperature) from the impact of fresh air, a significant reduction in the energy required for fresh air treatment to achieve energy efficient.
4, easy to use a variety of models, suitable for from 15m2 to 1100m2 building units, integrated structure, built-in heat exchanger, double fan, filter, just turn on the power and duct can be used, not only simplify the design, Various renovation projects.
5, safe and reliable low-noise fan and internal noise reduction, to prevent the impact on the outside world, the machine in addition to the fan outside the non-moving parts, almost no maintenance, to ensure long-term stable and reliable work.
6, low cost and high efficiency alternative to fresh air treatment equipment, do not have to operate the workshop, can reduce equipment investment and construction area, the use of heat recovery technology, energy saving, significantly reduce operating costs, saving wind energy consumption of more than 30% Heat supply, integrated structure to reduce maintenance workload.
7, the production of fine equipment components are used high-quality steel, environmental protection materials, aluminum frame, high quality, the appearance of fine.
Third, the new air ventilation unit configuration:
1. Filter configuration:
The air flow of the plate fin heat recovery is relatively wide, so the air quality is not too high, but the dirty, high dust content of the air will reduce its efficiency, so the fresh air exhaust into the side, should Respectively, plus the initial filter, the initial effect of the filter level should be G4.
2. Condensate configuration:
Plate fin heat recovery is divided into sensible heat recovery and total heat recovery, when the use of sensible heat recovery, the exhaust temperature difference between the larger circumstances, especially in the northern winter, fresh air temperature is much lower than the dew point of the exhaust temperature , Then there will be condensate discharge, so, in the ramp below, to be equipped with water tray, for organized drainage. When using full heat recovery, you can not set the water tray.
3. Fan configuration:
Small and medium sized air ventilation machine selection of external rotor type efficient low noise centrifugal fan. All the impeller of the fan are subjected to dynamic balance detection, impeller bearings using self-aligning maintenance-free bearings, has been filled with good high temperature grease, long service life. The outer rotor fan selected by the unit has low noise and good aerodynamic performance. The connection structure between the impeller and the volute makes it easy to replace the impeller bearing and the motor.
Fourth, the structure of fresh air ventilation unit:
The structure of the unit is framed (frame beam gluing plate). Modular design of the product, making the parts to achieve a standardized, general, greatly improving the production efficiency and shorten the processing cycle.
The frame of the unit is a closed aluminum alloy made of specially rolled rolling equipment, the cross-sectional shape is □, the box material is colored steel plate, the color steel plate is hot-dip galvanized steel, and the two-layer color resin , The latter coated with a layer, so its folding resistance, good weather resistance, corrosion resistance, acid, alkali, salt, 15 years do not fade; inside the internal control plate pressure δ = 30mm thick polystyrene or polyurethane insulation material, Greatly improving the rigidity of the unit shell and anti-corrosion ability; at the same time due to the non-absorbent material insulation, the unit will not be due to moisture and insulation performance decreased, so the unit's insulation performance and airtight performance excellent durability. The color of the color plate is pearl white.
The internal sheet metal parts of the unit are made of galvanized steel. The unit is sealed with a sealing tape between the box and the frame, with high temperature (+ 90 ℃), low temperature (-60 ℃), sealed Good sex, long life and other characteristics;
