Recently, people have always mentioned the fresh air system to me, what is the fresh air system?

Find the information directly on the Internet, do you think there is a use for you?

In modern buildings, with the continuous improvement of housing quality and energy-saving requirements, the airtightness of doors and windows is getting better and better. At the same time, the increasingly serious pollution of dust, exhaust gas, and noise in the city, coupled with the relatively high number of extreme weather such as cold, heat, and dust, has caused many families to completely close their doors and windows most of the time. In this way, how to ventilate becomes a big problem.

Indoor air quality directly affects our quality of life, and ventilation is the most direct and effective way to improve indoor air quality. The fresh air system came into being in this environment.

In Europe, the most widely used and technologically mature in the market today is the ComfoSystems. Sender Kangshu Fresh Air System is an energy-saving, healthy and comfortable controllable ventilation system. It works by:

First of all, the indoor dirty air is discharged to the outside after heating, and at the same time, the fresh air outside is filtered, sterilized, humidified or dehumidified, and then enters the Sender high-efficiency heater, and the temperature of the fresh air after heat exchange can be adjusted to a temperature close to room temperature without consuming any other auxiliary energy, and then sent to the room through the air duct. The entire ventilation process is continuous, homogeneous, quiet and clean. Due to the heat, the Sende Kangshu fresh air system is economical, the power consumption is very low, and the body feels comfortable, creating a soundproof, clean, comfortable and healthy living space.

Come to our company and take a look, hehe,

The fresh air system is an independent air handling system composed of air supply system and exhaust air system.

Fresh air system: It is composed of a machine, an air inlet, an exhaust outlet, a filter box and various pipes and joints. Installed in the ceiling of the kitchen or toilet, the machine is started, the indoor polluted air is discharged to the outside through the exhaust outlet, and the outdoor fresh air enters the room through the filter box and the air inlet, so that the indoor personnel can breathe high-quality fresh air.

Moreover, taking into account the conservation and reuse of energy, the exhaust air will be made hot**, and the **rate will reach more than 80% as a new energy source.

In order to pursue a healthy and quiet quality of life, 70 years ago in European countries a simple and practical system came into being, 90% of their buildings are installed with this system, the system has been very widely used, this is the best fresh air system.

This system is a continuous and efficient 24-hour uninterrupted circulation of indoor and outdoor air in the whole house, and it is an air replacement system to ensure indoor air quality. It ensures that there is fresh air in the room at all times, and is nicknamed "the respiratory system of the house".

The fresh air system is still relatively comfortable in nature, and the energy consumption of the fresh air system is very low, almost no power consumption, and the fresh air system can be opened 24 hours a day, so there is no need to worry about power consumption.

Air purifying air system.

The fresh air system is an independent air handling system composed of fresh air ventilator and pipeline accessories, and the fresh air ventilator filters and purifies the outdoor fresh gas and transports it to the room through the pipeline. At the same time, the indoor dirty air with low oxygen content is discharged from the outside.

Air conditioners and air purifiers can replace the problems of fresh air systems.

These are three completely different devices, and there is no substitution between them. You can also think of it as three different "species" for a better understanding.

The air supply function of the air conditioner does not introduce fresh air. To put it simply, it is a fan, which only regulates the indoor air circulation; Air purifiers, on the other hand, will not introduce fresh air. If the main vertical is to purify the fine dust and bacteria in the indoor air, there is no way to solve the gas pollution, such as formaldehyde, carbon monoxide, etc.

The fresh air system can realize indoor and outdoor air exchange, introduce fresh outdoor air, and discharge formaldehyde, carbon dioxide and other turbid air. But it can't serve the purpose of indoor cooling in summer, that is, even if you install a fresh air system in your home, you still need to install air conditioning.

The fresh air system is an independent air handling system composed of air supply system and exhaust air system, which is divided into two types: ducted fresh air system and ductless fresh air system. The ducted fresh air system is composed of fresh air fans and pipe fittings, which purify the outdoor air through the fresh air fan and introduce it into the room, and discharge the indoor air through the pipes; The plum-free slow dispersion duct fresh air system is composed of fresh air fans, which are also used to purify the outdoor air and introduce it into the room.

Relatively speaking, the piped fresh air system is more suitable for industrial or large-area office use due to the large amount of work, while the ductless fresh air system is more suitable for family use because of the easy installation. In 1935, after many attempts, Chunyi invented and manufactured the world's first heat exchange equipment that could filter air pollution, also known as the fresh air system.

Fresh air system, as the name suggests, is an independent air handling system for fresh air, it is mainly composed of air supply system and exhaust system, the fan extracts the outdoor air through the filter screen and sends it to the room, and 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.

Compose. The fresh air system is mainly composed of heat exchange system, power system, filtration system, control system, noise reduction system and box.

Power system: The power part of the fresh air system adopts high-efficiency, noise-reducing fans and motors. The outdoor fresh air after filtration, purification and heat exchange treatment is forcibly sent into the room, and at the same time, the indoor harmful gases after filtration, purification and heat exchange treatment are forcibly discharged outside.

Control system: The fresh air system selects reliable electrical components to achieve the control of different air volumes with safe, reliable and long-life operation. It can realize automatic, timing, mode adjustment, etc. Different control methods can be selected according to different use environments.

Filtration system: The filtration system of the fresh air system is divided into three types of filters: primary, medium, and high-efficiency. The ventilator is equipped with air filters at the two air inlets, which can effectively filter dust particles, fibers and other impurities in the air, effectively prevent the dust and other impurities in the outdoor air from entering the room to achieve the purpose of purification, and ensure that the heat exchange parts of the host will not be adhered to by pollutants and affect the performance of the equipment.

Heat exchange system: mainly full heat exchanger, when running, when the indoor exhaust air and fresh air flow through the heat exchanger core in a positive cross mode, the temperature difference and vapor partial pressure difference on both sides of the air baffle will cause the total heat exchange process, and the air entering the room will maintain a certain temperature, and it will not be too cold or too hot in winter or summer.

Classify. According to the installation method, it can be divided into two types: ducted fresh air system and ductless fresh air system.

Pipe-type fresh air has the blessing of pipes, which is more suitable for industry, large-area office areas, housing construction and other scenarios, and the amount of work is large, and pipe-laying can also be divided into ground air supply and top air supply.

Ductless fresh air is available in wall-mounted and cabinet types, which is suitable for decorated areas, and there are no long pipes, which can only take care of a single room.

It can also be divided into fresh air with full heat exchange and fresh air without full heat exchange.

If there is total heat, the indoor temperature control is better, and no air conditioning is consumed in winter and summer.

There is no total heat, the indoor temperature changes with the seasons, and it is not easy to maintain the temperature when the air conditioner is turned on.

According to the exhaust mode, it can also be divided into one-way flow and two-way flow.

The one-way flow system is the form of air flow organization 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.

The fresh air system, also known as the whole house purification system, is composed of a fresh air ventilator, a pipe, and an air outlet, which is mainly used for indoor air purification and ventilation.
