What is the new wind system? How to choose the new wind system?

The fresh air system is one of the best-selling purifiers on the market. Many people will install it when decorating. It can purify the indoor air very well. The fresh air system is actually an independent air treatment system composed of fresh air exchanger and pipe accessories. The fresh air exchanger filters and purifies the outdoor fresh gas and transports it indoors through the pipeline.

The fresh air system is an independent air treatment system composed of an air supply system and an exhaust air system, which is divided into a pipe fresh air system and a pipeless fresh air system.

How about the new wind system? Next, we will give you an answer one by one what is the new wind system? The fresh air system is composed of fresh air exchanger and pipe accessories.With an independent air treatment system, the fresh air exchanger filters and purifies the outdoor fresh gas and transports it indoors through the pipeline.

How to choose a fresh air system depends on the filtration effect. The filtration function of the fresh air purification system depends on the filter inside the machine. The air inhaled from the outside of the machine is filtered through the internal filter of the machine to ensure that all the air sent into the room is clean.

What is a fresh air system? What is a fresh air system? In fact, the fresh air system is an independent system composed of the host fresh air exchanger and pipe accessories. This product is a relatively new product at present. In fact, it is also very similar to the air conditioner.

What is the new wind system and what is it used for?

What is the function of the fresh air system to maintain indoor ventilation? Maintain indoor fresh air. The fresh air system can continuously provide fresh air to the room 24 hours a day, send the outdoor fresh air into the room after treatment, and discharge the indoor polluted air into the room through the air outlet, exhaust pipe and fan.

The fresh air system is a set of independent air treatment system for fresh air. It mainly has air delivery system and exhaust air.The system consists of the fan pumping the air outside through the filter net and sending it to the room, and the air in the room is discharged outside through the fan or air negative pressure, so that the fresh air outside can be breathed without opening the window.

Definition: The fresh air system is an independent air treatment system composed of a fresh air exchanger and pipe accessories. The fresh air exchanger filters and purifies the outdoor fresh gas and transports it indoors through the pipeline. Function: Simply put, it is to make your indoor air fresher.

The fresh air system is an air treatment system, which is widely used in various buildings, but the popularity rate is not high.

The filtration of the fresh air system is mainly divided into two types: pure physical filtration and electrostatic adsorption. Pure physical filtration is to use the filter element, while electrostatic adsorption is to use the static electricity generated by the electrostatic box to collect dust.

What is the new wind system?

The fresh air system refers to filtering the outdoor fresh air and sending it indoors. At the same time, the indoor polluted air is discharged to the outdoors. At the same time, the balance of the system is achieved and the air is replaced in the room, so that a closed space can achieve scientific air convection, which is also equivalent to adding a A respiratory system.

The fresh air system is an independent air treatment system composed of a supply air system and an exhaust air system. It is divided into two types: pipeline fresh air system and non-piped fresh air system. The pipeline fresh air system is composed of fresh fans and pipe fittings. The outdoor air is purified by the new fan and introduced into the room, and the indoor air is discharged through the pipe.

What does the fresh wind system refer to? The fresh wind system isA set of independent air treatment system composed of air supply system and exhaust air system, which is divided into two types: duct-type fresh air system and pipeless fresh air system.

The fresh air system is an independent air treatment system composed of an air delivery system and an exhaust air system. Working principle: The fresh air system is based on sending fresh air to the room with special equipment on one side of the closed room, and then discharging it from the other side to the outside by special equipment, which will form a "new air flow field" indoors, so as to meet the needs of indoor fresh air exchange.

The fresh air system is a mechanical ventilation device that actively injects clean air into the room and excludes the dirty air in the room, so that people can enjoy fresh air at all times without opening the window.

The fresh air system is an independent air treatment system composed of an air delivery system and an exhaust air system.The fresh air system is divided into two types: duct-type fresh air system and duct-free fresh air system.

What are the types of fresh air systems?

What are the types of fresh air systems? Monomer fresh air systems? The monomer fresh air system is a new wind system product newly launched in recent years, which includes two products: wall-mounted fresh air system and floor-mounted fresh air system. .

What are the types of fresh air systems? Classified according to the air supply method, one-way fresh air system. The one-way flow system is a diversified ventilation system formed by the combination of central mechanical exhaust and natural air intake based on the three principles of mechanical ventilation system. It is composed of fans, air inlets, exhaust ports and various pipes and joints.

The fresh air system can be divided into a pipe-type fresh air system (central fresh air) and a pipeless fresh air system according to the installation method.New fans without pipes include cabinet new fans and wall-mounted new fans. According to different ventilation principles, the fresh air system can be divided into two categories: one-way flow and two-way flow, and the major categories also include different product classifications.

[Classification and advantages and disadvantages] The fresh air system can be divided into: one-way flow fresh air system, two-way flow fresh air system, positive pressure air delivery system, etc.

Types of fresh air system Among the pipe-type pipe-type fresh air system, the negative pressure new fan belongs to the bottom. The structure is very simple, the technical content is very low, and there are only the shell and fan. The positive pressure fresh air system has a purification function, and some styles even add electric auxiliary heating function, which is of a higher grade.

New Wind System Installation Guide

1. How to Install New Wind System - New WindThe installation position of the main body of the system is generally in the ceiling of the bathroom, balcony or kitchen. When installing, it should be noted that it should not be too long from the air duct, and it is best to install the machine in the air duct, and its channel should also avoid bends, so as to reduce the resistance.

2. Determine the installation location: The fresh air system is usually installed in the ceiling of the house, so you need to determine the installation position of the fresh air equipment, which is usually the middle area of the house. At the same time, you need to consider the location of the power socket of the fresh air equipment, which usually needs to be installed in the ceiling.

3. The installation of the fresh air system is mainly divided into host hoisting, pipeline installation and air duct connection with the host, etc. The installation position of the host is generally in the ceiling of the bathroom, balcony or kitchen. When installing, pay attention to the fact that it should not be too long from the air duct, and it is best to install the machine in the air duct, and its channel should also avoid bends, so as to reduce the resistance.

4. The principle of pipeline layout of fresh air system is to shorten the pipeline as much as possible, reduce branch pipelines, and avoid complex local components to save materials and reduce local wind resistance. Try to avoid the installation of the pipe at a right angle. The connecting pipe fittings can use a Y-shaped oblique tee, or use two 45-degree elbows to gently over.

Necessity of fresh air system

1. Fresh air system is suitable for pregnant women, allergic rhinitis or asthma patients and the elderly. It is mainly suitable for installation under very poor external air quality (smog, sand dust, etc.), or external Install when the temperature is not suitable to open the window.
