Is it necessary to turn on the new fan 24 hours a day?

1. In developed countries such as Europe, America and Japan.

Fresh fans are standard, and most new homes are equipped with fresh fans, and they will be turned on and operated for a long time without interruption after installation, and the shutdown button setting is designed for long-term operation.

2. Insufficient indoor oxygen caused by poor ventilation will affect physical health.

We spend most of our lives indoors without ventilating carbon dioxide.

will fill the entire space. The indoor closure makes the exhaled CO2 gas unable to be discharged outside, resulting in insufficient indoor oxygen, long-term exposure to carbon dioxide exceeding the standard, and dizziness.

Chest tightness, difficulty concentrating, work efficiency.

Reduces symptoms and affects physical health.

3. We need a good breathing environment with continuous ventilation.

Formaldehyde in indoor decoration will continue to be released for more than 10 years, the new fan will continue to run 24 hours a day, and Rolet will continue to introduce fresh air, and simultaneously dilute and discharge harmful gases such as oil smoke odor, cigarette smell, bacteria, and viruses to the outdoors, so that the home has been in a clean and oxygen-rich state, making our life healthier.

Fresh air needs to be replaced indoors 24 hours a day, many friends may be worried about the energy consumption of turning on the fresh fan for a long time, in fact, the power consumption of the 24-hour fresh fan in ordinary families is similar to that of a household refrigerator. The refrigerator in our family is open 365 days a year and not many people think it is expensive, relatively healthy, similar to the power consumption of the refrigerator, low energy consumption, in order to clean the air, it is necessary to open it 24 hours a day.

Out of the air, the limit of human survival is 3, 6 minutes. In recent years, with the continuous improvement of living standards, people have higher and higher requirements for a healthy living environment, especially under the influence of the new crown pneumonia epidemic, respiratory health has become the focus of people's attention. Therefore, many people choose to install a fresh air system when decorating their homes to create a healthy and clean air environment.

Of course, there are also many people who will ask, in the usual home life scene, does the fresh air system need to be turned on 24 hours a day?

We need to know that in the process of breathing, people exhale a lot of carbon dioxide on the one hand, and consume oxygen in the air on the other hand, and a person exhales about 22m of CO2 gas per hour, which is about 528 m at the end of a day. When the doors and windows are closed, there is too much CO2 in the indoor air and the oxygen content is insufficient, a state of micro-hypoxia is formed, and ventilation is the main cause of micro-hypoxia.

Generally speaking, it is best to turn on the fresh air system 24 hours a day. Because fresh air is a huge air replacement system, if it is turned on and off for a while, frequent start and stop will not only be harmful to the equipment, but also cannot provide fresh air continuously. If we turn on the fresh air system 24 hours a day, we can keep the room in a clean state and avoid secondary air pollution.

So the new problem is here again, does the fresh air system consume a lot of power when it starts 24 hours a day? Will I have to pay a high fee?

In fact, an ordinary apartment turns on a blower with a 100 air volume for 24 hours, and the power is 24 hours for operation. In this way, the fresh air system at home only consumes 1 4 kilowatt-hours of electricity per day, only 1 cent, and if it is calculated according to 365 days a year, it costs about yuan. Compared with turning on the air conditioner, turning on the fresh fan for a long time can be regarded as an economical choice.

However, it should be noted here that it is best not to use the ordinary fresh air system in hazy weather. Some small household fresh air systems are only installed with a filter layer that filters pollutants such as large particles of dust, and they cannot filter the air. If the fresh air system is turned on in hazy weather, the indoor air will be full of dirty air, which will cause secondary pollution to the indoor environment.

To avoid this, you can choose to install a fresh air fan with a high-efficiency filter.

If necessary, it is better to say that the fresh air is recommended to be turned on 24 hours a day.

Fresh air is mechanical ventilation, which forcibly transports fresh air into the house through fresh air fans, and discharges the dirty air to purify the air and reduce the concentration of carbon dioxide. Only when the new fan is in continuous operation can fresh air be continuously introduced and exhaust gases discharged.

People breathe all the time, so they need fresh and clean air all the time, whether we are indoors or not, indoor decoration, human activities, etc. will emit all kinds of fine particles and harmful gases. For example, various furniture and panels in decoration contain formaldehyde, and the volatilization cycle is as long as 3-15 years. If you are not at home, turn off the fresh air, and the circulation of the fresh air system takes time, and it takes more than an hour for you to turn it on again when you return home, and the air quality in your home will improve.

In addition, the energy consumption of the fresh air system is not too high, and the electricity consumption may not be as good as that of a refrigerator if it runs continuously 24 hours a day, and it can also reduce the energy consumption of household appliances such as indoor air conditioners.

However, it is worth noting that the new fan mainly uses the filter to filter pollutants in the air, and the continuous opening of the filter 24 hours a day will make the filter saturated faster, if not replaced in time, not only the energy consumption will increase, the purification efficiency will decrease, but also will lead to secondary pollution. Therefore, it is already necessary to replace the filter in time, or consider a new fan that does not need a filter.

It is best to turn on the fresh air system 24 hours a day. The fresh air system is a huge system, if it is turned on and off for a while, it is not only a harm to the equipment, but also cannot continuously provide fresh air and exhaust the dirty air in the room. If we turn on the fresh air system 24 hours a day, we can keep the room in a clean state and avoid secondary pollution.

This depends on the environment you are in, if the room is a closed environment, the new fan is indeed necessary to be turned on, if it is not a closed environment, then there is no need to turn on 24 hours.

Once the fresh air system is turned on, do not turn it off at will, because only in this way can you continuously breathe fresh air and ensure that clean air penetrates every corner of the room. Moreover, the general household fresh air system has low energy consumption, and it will not increase too much cost for long-term operation. Therefore, it is necessary for the fresh air system to run 24 hours a day.

There is no need for the new fan to be turned on 24 hours a day, this should be turned on for a period of time, and if it is turned on 24 hours a day, it should also have a certain impact.

If there is always someone, you can keep it on.

If there's no one after work.

There's no need to keep it open.

Also, if you can open doors and windows, you don't have to keep them open.

Although the air purifier is turned on for a few hours, the service life is greatly reduced and the cost increases. Therefore, it is recommended that the machine rest properly, but it is not recommended to turn on the machine for several hours. If you feel that the dust pollution in your home is not frequent, you often need to clean it.

However, because the air quality near the home is so poor, dust particles in the air enter the home through the outside and then attach to the walls of the furniture floor. The way to do this is to turn on the air purifier for a few hours a day to filter dust and bacteria from the air, breathe healthy indoors, and reduce.

Regardless of the problem of electricity bills, it is best to run 24 hours a day, the outdoor air is relatively fresh or the home can be turned off if people do not live for a long time, with the continuous strengthening of the country's environmental governance, the air quality is getting higher and higher, and the necessity of the fresh air system is getting smaller and smaller.

I don't think it's necessary for the new fan to be turned on 24 hours a day, because the load on it is also very large, so I don't think it should be able to be turned on 24 hours a day.

It is recommended to use a fresh fan for a few hours, and then open the window for ventilation, if you keep it open for 24 hours and do not open the window for ventilation, this is not good.

If the fresh air system is turned on, it will not be turned off under normal circumstances. The replacement of the filter screen depends on the off-grid grade and the local climatic conditions, if it is a low-grade and medium-grade filter, it will take 3 to 6 months to replace, and if it is a high-grade rate screen, it will take 6 to 12 months to replace. Of course, if the local climatic conditions are harsh, the replacement time needs to be appropriately shortened.

If you want better and cleaner air, you can naturally replace the filter more frequently, so as to achieve the purpose of purifying the air. The main reason why you choose to replace the filter is because the filter is a basic consumable in the design itself. Its main function is to keep dust and other pollutants in the air out, but if not replaced, these pollutants will collect on the filter.

Once the fresh air system is turned on, these pollutants may enter the room due to the pressure difference between indoor and outdoor, thereby polluting the indoor air, so it is necessary to replace the filter in time. <>

The filter replacement interval depends on the local air environment to the greatest extent. If the environment is very poor, it is usually necessary to replace the filter every two to three months. Moreover, the replacement of the filter is not simply to take it out for cleaning, because this will damage the structure of the filter, so that it has no way to better absorb pollutants in the air.

This is also why although the fresh air system has been born for a very long time, it has not entered thousands of households, because its use cost is relatively high. <>

Now there is a new electronic purification filter, which is designed to adsorb pollutants in the air into a designated space through the principle of high-voltage electrostatic adsorption. We only need to open the integrated box within the specified time and clean up the pollutants inside, without replacing the filter, which will not only reduce the cost of using the fresh air system, but also be more efficient and convenient, and it is not easy to have secondary pollution.

In order for the fresh air system to work, we must keep it running in order to bring a steady stream of fresh air to the room. It is best to open the fresh air system continuously for 24 hours, so that the indoor air can be kept in a clean state and avoid secondary pollution. In fact, the power consumption of an ordinary apartment 24 hours a day is similar to that of a household refrigerator, compared to turning on the air conditioner, turning on the fresh air fan for a long time can be regarded as an economical choice.

The fresh air system can work 24 hours a day, continuously delivering clean, fresh and healthy air to the room, and at the same time exhausting the original dirty air into the room, which can effectively control the air volume and maintain the freshness of the indoor air. Fresh air is introduced through fresh air outlets installed on the windows of bedrooms, living rooms or living rooms, and then connected by corresponding indoor pipes to exhaust air outlets in several functional rooms to form a circulation system to exhaust indoor dirty air.

When using the fresh fan, it is recommended to turn on the machine 24 hours a day, so that only the secondary pollution is avoided, the air at home is always in a healthy and clean state, and the respiratory health of the family is fully cared for, and the power of the fresh air host is generally low, even if it is turned on for 24 hours, the power consumption is much lower than when the air conditioner is turned on, and the consumption of 24-hour continuous operation is acceptable.

For example, a 100-square-meter house adopts a Kidman Sol series 250 air volume cabinet fresh air system, which operates 24 hours a day, and the electricity bill for a day is only one yuan, and the electricity fee of 615 yuan a year is completely within the acceptable range.

Yes, in this way, fresh air can be continuously supplied to the room, and at the same time, the dirty air in the room can be exhausted to ensure the health of the people in the room.

Of course, the fresh air system is an independent air handling system for fresh air, which is mainly composed of air supply system and exhaust system, the air outside the fan is filtered through the filter screen and sent to the room, the indoor air is sent out from the exhaust pipe, and the indoor air is constantly replaced, so that you can breathe fresh air outside without opening the window. Because it is constantly ventilating, it can dilute the indoor formaldehyde content to a certain extent to the normal index.

Fresh air can be turned on for a day, and at the end of the day, the power consumption is almost only 3-4 kWh, and the electricity consumption cost is only about 2 yuan a day.

The fresh air system is mainly divided into one-way flow and two-way flow according to the exhaust mode, and the one-way flow system is the airflow organization form of "mechanical air supply and natural exhaust". Only the air supply outlet is set up indoors, and fresh and clean air is continuously sent to the room, and the dirty air is discharged through the cracks in the doors and windows.

The two-way flow system is the airflow organization form of "mechanical air supply, mechanical exhaust". At the same time, air supply outlets and exhaust outlets are set up indoors, and fresh and clean air is sent into the air supply outlets, and dirty air is discharged to the outdoors through the exhaust outlets.

In fact, the household fresh air system generally has very little power, even if it is turned on for 24 hours, it will not consume much power, and the effect is good.

Unidirectional flow system Generally, the machine is 25W H, which means that only about 24 hours of electricity consumption.

Two-way flow system: the normal machine is (45*2) w h, that is to say, the power consumption is about 24 hours.

Ordinary apartment houses, generally choose a silent blower, the minimum air volume of the household fresh air system is 180m, and its power is 25W.

Villa-type houses generally use a full heat exchanger for ventilation through the heat exchanger, which is very energy-efficient. The air volume of the hot ** fresh air system is 200m, and the power is only 45W.
