What are the design features of the home fresh air system?

Home fresh air system design - choose the appropriate damper, in principle, the error of the system air pressure balance is within 10% 15%, you can not set up a regulating valve, but in fact, it is very difficult to adjust the air pressure only by the size of the air control pipe, so it is necessary to set up an air volume regulating valve to adjust. An air volume regulating valve should be set at the branch of the air duct. A three-way control valve can be set at the three-way branch, or a control valve can be set at the branch.

Significantly unfavorable loops can be left without a control valve to reduce resistance loss. Where the fire damper is required, the fire control valve can be used instead of the control valve. The louver tuyere at the air supply outlet should use the air supply outlet with a regulating valve, and the double-layer louver tuyere can be used to adjust the air volume with the adjustment tuyere angle.

The fresh air inlet should be equipped with a damper that can be tightly opened and closed, and a thermal insulation damper should be installed in severe cold areas, and an electric damper should be used when there is automatic control. The design of the home fresh air system - the arrangement of the air duct should minimize the local resistance, that is, reduce the number of elbows, tees, and reducers. The radius of the center curvature of the elbow should not be less than the diameter or side length of the air duct, and the double diameter or side length can generally be used.

In order to facilitate the adjustment of the air duct system, pressure measuring holes should be reserved before and after the branch point of the main pipe. The distance between the pressure measuring hole and the local pipe fittings in front should be greater than 5b (b is the long side of the rectangular air duct or the diameter of the circular air duct), and the distance from the local pipe fittings behind should not be less than 2b. Pressure measuring holes should be reserved on the pipe section where the airflow is more stable at the outlet of the ventilator.

Home fresh air system design - the location of the fresh air inlet, the air inlet should be located in a place where the outdoor air is relatively clean to ensure air quality. It should be located on the north wall, avoid the roof and west wall, and should be located in the shade of the building, so that the outdoor air inhaled in summer can be cooler. The bottom of the air inlet should not be less than two meters from the outdoor ground, and when the air inlet is arranged in a green belt, it should not be less than one meter.

It should be arranged on the upwind side of the exhaust outlet as far as possible, and lower than the exhaust outlet, and try to maintain a distance of not less than 10 meters. Installing a home fresh air system at home can make our indoor air more circulating, so that you can breathe fresh air, therefore, there are many people who choose to install a home fresh air system, when designing a home fresh air system, we should understand the above precautions, so that we can better install the home fresh air system, so that we can breathe high-quality air.

1: Regarding the air supply mode, in terms of the use effect and air convection diffusion, the effect of ground air supply is better than that of top air supply; In terms of installation difficulty and cost, the popularity of ground air supply is not as high as that of top air supply, so the corresponding cost and difficulty are a little higher; As for the loss of wind pressure, it depends on the specific pipeline system; In terms of later maintenance, it is difficult to clean and maintain the pipeline part of both, and as for the air outlet part, it should be noted that the air outlet of the ground air supply is easier to enter the sundries, so it is generally recommended to set the air outlet of the ground air supply on the wall surface during the construction process to make the form of wall air outlet;

2: Regarding the choice of pipe diameter, as far as the machine with 350 air volume is concerned, it is best to choose 160 pipes, but as far as home decoration is concerned, it is difficult to lay out 160 pipes well, and 110 pipes are enough, as for the end of 75 pipes, it will not be a big problem to pull a few more branches, and the noise and wind speed will be more reasonable.

**The fresh air system is generally installed in the parts with suspended ceilings above the kitchen and bathroom, dining room and corridor corridor, so it will not affect the decoration effect. Its installation time is generally laid before the construction of hydropower.

1) The household fresh air system can drive away a variety of different indoor air pollution, provide you with quality fresh air, and avoid the noise troubles caused by opening windows for ventilation, the pain of frequent cleaning of indoor sanitation and the embarrassment of forgetting to close the windows when going out;

2) The system can indirectly prolong the life of the building, especially to prevent the mold of the building;

3) The system can ensure long-term continuous operation, and has high reliability, low energy consumption and low noise;

4) The system is widely used in high-end residential areas, villas, hospitals, offices, hotels, hair salons, guesthouses and other places.

Pollution in many areas is becoming more and more serious, many people will have air purifiers or household fresh air systems at home, fresh air systems are similar to air purifiers, but the performance is better than air purifiers, but household fresh air hail systems still need to be installed, not like air purifiers to buy and use directly, although the household fresh air system is not popular, but it has attracted the attention of many people, let's take a look at what the household fresh air system is, what are the orange smiles.

1. What is the household fresh air system?

The home fresh air system is a tool that wants to be similar to an air purifier, like an air purifier, to deliver clean air indoors, and at the same time remove dirty air, creating a kind of circulation, so that you can enjoy fresh air indoors without opening the bed.

2. What are the types of fresh air systems?

1. One-way flow of fresh air

Unidirectional flow fresh air can only be sent to the home or exhaust air, because it is a single fan, so it needs to be used with window fresh air, otherwise it can not be circulated, and the outdoor unfiltered gas will also enter the room, which is easy to form a negative pressure space at home, and the filtration effect is general.

2. Two-way flow of fresh air

Different from one-way flow fresh air, two-way flow fresh air is that in addition to exhaust and supply air, it can also filter outdoor air in, equipped with air supply outlets and air outlets, forming a circulation, but the cost is higher.

3. Self-balancing fresh air

The simplest fresh air only needs to be installed on the wall with a device similar to a fan, which is less effective and does not meet the requirements of fresh air.

4. Full heat exchange fresh air

As an enhanced version of the two-way flow fresh air, it adds a full heat exchange function, similar to air conditioning heating, and prevents cold air from entering the room in winter, saving energy and having a better air purification effect.

Pursuing a high-quality life and enjoying fresh air at home, the fresh air system is the first choice for most people who have requirements for life. In order to let more people understand what the function of the fresh air system is, I will briefly give you the functions of the general household fresh air system.

The advantages of the household fresh air system are mainly in the home environment, which can effectively regulate and control the air and improve air quality

First, create an indoor air environment that is suitable for human comfort. Because the indoor air environment plays a very important role in the comfort of the human body, the indoor air environment required to create the comfort of the human body has become the primary task of the household fresh air system.

If the indoor air temperature is required to be 24, the relative humidity is 55%. Then the air conditioner should be kept at a temperature base of 24 and a humidity base of 55%.

Second, the indoor air environment that meets the needs of process production. Some processes require extremely high temperature and humidity environments. Temperature and humidity conditions not only directly affect the normal progress of the production process, but also affect the output and quality of products, such as textile production, dense instrument production and drug production process.

Third, the elimination of indoor harmful gases and concentrated heat and humidity, carbon dioxide in the household fresh air system and bad odors in the bathroom, process air conditioning'The toxic, odorous and other harmful gases generated in the production workshop need to be eliminated through air conditioning and exhaust facilities, so as to obtain a good indoor air environment.

Therefore, in order to improve air quality in people's living and working environments, it is necessary to take proactive measures to use mechanical kinetic energy to adjust the indoor air structure. If there is a good indoors space for Hu Qichang, choose the fresh air system to make indoor and outdoor air convection and enjoy fresh air.
