I. Introduction

With the continuous improvement of people's pursuit of quality of life, fresh air system has gradually become one of the necessary equipment for modern home decoration. The fresh air system can effectively improve the indoor air quality and keep the air fresh and comfortable. Installing a fresh air system in a new home is one of the important elements of creating a healthy and comfortable living space. This article will discuss in detail the elements of installing fresh air in a new home, including the selection of suitable equipment, system design and installation process.
Second, choose the right equipment
1. Understand the types and characteristics of fresh air systems
Before choosing a fresh air system, we must first understand the different types of fresh air systems and their characteristics. At present, the common fresh air systems on the market include suspended ceiling type, vertical cabinet type, floor type, etc. You need to select the right type of equipment based on your needs and house structure.

2. Determine device parameters and specifications

According to the housing area, the number of floors, the use of functions and other

 factors, determine the parameters and specifications of the fresh air system. Including 

air volume, noise, energy efficiency and other indicators to ensure that the fresh air system

 can meet the actual demand.

3. Choose well-known brands and quality products

Choosing well-known brands and high-quality products is an important guarantee for the

 installation of fresh air systems. High-quality products with better performance and

 longer service life can bring a better air quality experience to the home.

Third, system design

1. Determine the layout and location of the fresh air system

According to the structure and actual needs of the house, determine the layout and 

location of the fresh air system. The information includes the positions and number of air 

intake and exhaust vents, and the installation positions of devices.

2. Design a reasonable piping system

The piping system design of fresh air system is very important to the performance and 

use effect of the whole system. It is necessary to design a reasonable pipeline layout and

 pipe diameter according to the structure and actual needs of the house to ensure

 unimpeded air circulation.

3. Consider energy saving and environmental protection

In the process of system design, energy saving and environmental protection factors 

need to be considered. Choose efficient heat recovery devices and low-energy equipment

 to reduce energy consumption and environmental pollution.

4. Installation process

1. Prepare tools and materials

Before installation, prepare required tools and materials, including pipes, air valves, and 

sealing materials. At the same time, ensure that the equipment and pipes are clean to 

avoid the pollution of debris and dust.

2. Install devices and pipes

Install equipment and piping according to design drawings and installation instructions. 

It is necessary to pay attention to the connection and sealing of the pipe to ensure that 

the air flow is unimpeded. At the same time, to avoid damage and deformation of 

equipment and pipelines.

3. Connect the power supply to the control cable

Connect power and control lines according to equipment requirements. Pay attention to

 whether the voltage and phase of the power supply meet the requirements of the 

equipment, and whether the connection of the control line is correct and reliable.

4. System debugging and acceptance

After the installation is complete, the system is debugging and acceptance. Check that the

 running status and performance indicators of the device meet the requirements to 

ensure that the fresh air system can run normally and achieve the expected results.

Fifth, late maintenance and maintenance

1. Check and maintain the device regularly

Thefresh air system requires regular inspection and maintenance of the equipment, 

including cleaning the filter and checking whether the pipe connection is loose. Regular 

maintenance can ensure the normal operation of the equipment and extend the service 

life.

2. Pay attention to environmental hygiene and safety

Environmental hygiene and safety should be paid attention to when using fresh air 

systems. Avoid placing debris and flammable materials near the equipment, and regularly

 open Windows for ventilation to keep indoor air circulation. At the same time, avoid 

equipment damage or safety accidents caused by overuse or misoperation.
