How to ventilate a house without windows

Abstract: A good house needs good light, transparent vision, ventilation, warm in winter and cool in summer. Only convection windows can ventilate rooms, but some small or special units have no windows. An unventilated space will not only breed bacteria, but also have a heavy musty smell. Waiting for a long time in an unventilated room will have an impact on our health. So how to ventilate a house without windows? Let's take a closer look. How about air convection in windowless offices 1? The exhaust fan can punch holes in the wall. The exhaust fan can not only extract air, but also inhale air. It can be opened alternately to change the indoor air.

2. Air conditioning can be installed indoors, which can not only change the indoor air, but also have the function of heating and cooling.

3. An air pump can be installed at the top of the indoor wall. The air pump should be higher than the roof and extend upward. A rain cap should be installed at the air outlet to prevent water from entering in rainy days.

4. A ventilator can be installed indoors, just like an exhaust fan, which is specially used for ventilation.

5. Always keep the office door open and open more doors to let the outside air communicate with the room, but the circulation effect will not be very good.

6. Use an air purifier. Many offices are structurally poorly ventilated. At this time you need an air purifier to solve your problem.

How about the fresh air system in the windowless office? The fresh air system is used to update the indoor air for customers who do not have the window opening conditions. The fresh air main engine can be installed on the ceiling, and the dirty air can be discharged through the fresh air pipeline and the exhaust port on the ceiling; At the same time, fresh air is sucked in from the outside through another fresh air pipeline, or according to the negative pressure principle, fresh air is sucked in through the wall air inlet while air is discharged. The fresh air system of windowless office is simple in structure and low in cost.

Use of fresh air system in windowless office and matters needing attention 1. The fresh air outlet and its surrounding environment must be clean to ensure that the fresh air is not polluted. It is suggested to turn off the humidification function of air conditioning ventilation system.

2. Before and after work every day, the fresh air and exhaust system should run 1 hour in advance or continuously, and be fully ventilated to ensure fresh indoor air.

3.u-shaped pipes, such as sewer pipes, water seals of air handling devices, floor drains of bathrooms, condensed water drainage pipes of air conditioning units, etc., should be inspected regularly, especially in rooms, corridors and bathrooms that have been vacant for a long time. When there is water shortage, it is necessary to replenish water in time to avoid air mixing between different floors.

How to ventilate the windowless office building 1 Installing fresh air system can ensure ventilation demand and bring clean oxygen-enriched air; In addition to ventilation, the fresh air system can also filter the air, and the air entering the room becomes clean after filtering. The dirty air is constantly exhausted, making the room in a state of ventilation at any time.

2. When there are no windows in the exhaust fan office building, we can install several exhaust fans at the top, which can promote the indoor air circulation. It can make the office air better. This method is better.

3, put green plants You can put some green plants in the office, they can absorb formaldehyde and make the air better; When there is no window, the air circulation is poor, so there are more harmful substances indoors. It's better to put some green plants.

4. It is also good to use an air purifier. The air purifier can monitor the environment of the office building in real time, and then tell us what to do next through the warning light.

Is the fresh air system of windowless office building good? 1. You can enjoy the fresh air of nature without opening the window. It can provide fresh air for the office building 24 hours a day, 365 days a year, and you can enjoy the fresh air of nature without opening the window to meet the health needs of the human body.

2. Removing harmful gases released slowly for a long time after indoor decoration is beneficial to human health, discharging harmful gases and effectively discharging various unhealthy or harmful gases such as CO2, smoke, bacteria and viruses.

3. Remove musty smell and peculiar smell, and avoid office supplies from becoming moldy in the office building; Venting humid and dirty indoor air, eradicating peculiar smell and preventing the growth of mold and bacteria are beneficial to prolonging the service life of buildings and office furniture.

4, ultra-quiet, reduce noise pollution, do not have to endure the interruption caused by opening the window, so that the office is more quiet and comfortable.

5. Avoid a lot of dust caused by opening the window, effectively filter the outdoor air and ensure that the air entering the room is clean.

Use and matters needing attention of windowless office building 1 fresh air system. Clean, disinfect or replace the cooling tower, filter, filter screen, purifier, tuyere, air handling unit, surface cooler, heater (humidifier), condenser and other equipment or components of the fresh air system every week.

2. Frequently starting and stopping the fresh air system will not only increase energy consumption, but also damage some components of the fresh air system and affect its service life. It is suggested that the fresh air system can be turned on 24 hours to update the indoor air quality in real time and keep it clean and oxygen-enriched.

3. The total heat exchange fresh air system is equipped with a filter screen and a total heat exchanger core, which should also be replaced and cleaned in time.

What equipment is used for ventilation in commercial places? 1, the fresh air volume of fresh air air conditioning is very small, and the fresh air volume can be reasonably configured according to the space size. Only the air inlet, fresh air inlet and dirty air outlet are configured, so that ventilation in two directions can be carried out at the same time. However, it is limited by the season of use, not by the season of use.

2. Large pipeline fresh air ventilation system, central fresh air purification system, large mainframe, multi-pipeline, multi-suite * * use system, no pipeline, independent separation, indoor and outdoor air direct circulation system; But the pipe network is easy to cause secondary pollution or cross infection of bacteria.

3. Negative ion generator (oxygen bar) Negative ion generator can exchange and circulate indoor and outdoor air, which can basically solve the pollution problem.

How about the fresh air system in the business place? The commercial fresh air system can convey outdoor fresh air to the room through pipes after filtration, purification, oxygenation and temperature adjustment, and at the same time discharge indoor dirty air to realize air replacement and ensure the healthy living environment of indoor personnel. Due to the large flow of people and insufficient ventilation in commercial places, it is more necessary to install fresh air systems to ensure the indoor air quality meets the standards. Therefore, the commercial fresh air system has been widely used in these large commercial places.

How to keep ventilation in the windowless bathroom 1 Now many Yuba have ventilation function, which can realize rapid ventilation and exhaust and reduce the odor in the bathroom. Although it is not as good as windows, it largely makes up for the shortage of bathroom windows.

2, the bathroom without windows is easy to produce a lot of odor, affecting the mood of use. It is very important to choose a bathroom with good sewage discharge capacity and high water seal to eliminate the odor of the bathroom.

3. Pay attention to keeping the bathroom clean and tidy at ordinary times and clean it in time; In addition, flowers and green plants can be placed to improve the odor of the bathroom, and it can also make the bathroom more fresh and beautiful.

4. Wet and dry separation can be used in the bathroom, which can not only effectively collect water vapor to prevent more places from being wet, reduce the damage of water vapor to household appliances and furniture, but also prevent bacteria from breeding.

How to install fresh air system in windowless bathroom is ok, but the cost is high. Due to the addition of mechanical air supply system, the system is complicated and the investment is large. At the same time, there are some problems in the bathroom, such as the intersection of air supply and exhaust pipes affects the ceiling height, and the air supply outlet of the bathroom affects the decoration style. In addition, we should also pay attention to the relative position of the air inlet and air outlet in the bathroom to avoid the short circuit between the air inlet and air outlet from affecting the fresh air quality.

Is it necessary to install fresh air system in windowless attic? The air convection in the attic is not smooth, so it is necessary to install not only air conditioning but also ventilation equipment, which can further improve the ventilation situation, and also complex air supply equipment, such as fresh air system.

Windowless attic fresh air system 1, durable. Like the hydropower system, the home fresh air system is integrated with the building, so that the house has the breathing function and runs 24 hours without interruption like a human heart and lung. Therefore, when choosing a home fresh air system, try to choose a durable and reliable brand.

2, ventilation effect The household fresh air system should have sufficient ventilation, and it is best to use two-way flow, with ventilation in and out, scientific and reasonable airflow organization and good ventilation effect; Don't leave a dead angle, breathe continuously, so that the human body can breathe fresh and pure air at all times.

3. The energy-saving fresh air system in the attic must have the function of heat recovery, so that the inlet and outlet air can exchange energy through preheating and precooling when passing through the heat exchanger, which can reserve most of the energy of indoor air, avoid energy loss, reduce the loss of cold and warm air, and achieve good energy-saving effect.

4. Silent effect The fresh air system in the attic needs to run smoothly and quietly. If the domestic fresh air system is noisy, it is nothing more than replacing air pollution with noise pollution. You can hardly feel the existence of a good home fresh air system when it is running.

Installation of fresh air system 1 in windowless attic, selection and laying of pipes PVC pipes or galvanized air pipes are generally used in China, which has the advantage of long service time, but it is easy to accumulate dust and difficult to clean; If conditions permit, it is still recommended to use imported food-grade pipelines. When laying, avoid right-angle bending and pipeline crossing, and keep the whole pipeline warm in front of the heat exchanger to avoid condensation; In the outdoor exhaust part, it is necessary to install a check valve to prevent outdoor air from flowing back through the unfiltered part.

2. The biggest function of fresh air system with filter screen is to filter outdoor air, and the core is filter screen; Pay attention to two points when choosing a filter. You can choose the electrostatic adsorption filter, but don't choose the one that generates static electricity through the electrostatic generator. The generation of static electricity will inevitably bring ozone pollution indoors and endanger human health.

3. The air inlet of the outdoor air inlet should be as straight as possible from the fan, because the outdoor air may contain a lot of particles. If the pipe is bent, the airflow will be concentrated on one side, so that the filter screen will be partially blocked. The outdoor air inlet and outlet should be as far away from the air supply outlet and air return outlet in the same room as possible to prevent the fresh air that has just entered the room from being discharged immediately.

Precautions for the use of fresh air system in windowless attic 1, dust collection filter screen, medium and low efficiency filter screen and high efficiency HEPA of fresh air system all need regular maintenance, because in the daily operation of fresh air system, due to static electricity, dust is easy to be adsorbed on the filter screen for a long time, which will easily lead to bacterial growth in the long run, leading to air quality degradation, affecting the life of fresh air system and other hazards.

2. When you have a rest at night, you can set the fresh air system to off-screen mode, touch the setting key, enter the backlight setting at the back, and then click the scheduled rest screen/bright screen setting. Turn on the timer screen/light screen and set your own sleep time. After the time is saved, the screen turns black and the machine runs normally.
