The importance of installing central air conditioners. I believe everyone who wants to install important air conditioners knows it. What this article wants to popularize is the illustration of the installation process of central air conditioners, so that everyone can understand the installation process of central air conditioners more intuitively. Before installation, the first thing to do is to conduct an on-site survey, and based on the survey data, design reasonable cabling, piping and other plans, and draw construction drawings. This is absolutely indispensable. When problems arise later, you can refer to the drawings. Hold accountable.
1. Central air conditioning installation steps
Now that we have prepared reasonable design drawings, what I want to tell you is the construction process and related schematic diagrams.
The first step: Preparation work
The equipment and materials are placed in accordance with the standards. They will be unpacked and constructed after the customer has passed the acceptance. The acceptance of the equipment and equipment is very important. The construction must be started only after acceptance.
Step 2: Hoist the indoor unit
Horizontal installation: The indoor unit must be installed horizontally to ensure smooth drainage and no accumulation of water in the water pan.
Indoor unit protection: After hoisting, the indoor unit should be wrapped with plastic bag film and other materials in time to prevent dust intrusion.
Step 3: Refrigerant piping processing
Cutting account pipes: When welding refrigerant piping, the pipe should be expanded instead of expanded to ensure quality and prevent refrigerant leakage.
Copper pipe welding: In order to avoid the generation of oxides, nitrogen must be replaced during welding, and the copper pipe must be allowed to cool naturally.
Step 4: Laying refrigerant piping/drainage pipes
Refrigerant piping: A support must be set every 1.2m-1.5m to ensure firmness,
Drainage pipes: A slope of at least 1/100 should be maintained and one should be set every 0.8m-1m. support.
Step 5: Install the outdoor unit
Make sure the air outlet is unobstructed and keep the air flowing freely to prevent return air short circuit, and pay attention to leaving enough space for maintenance.
Step 6: Fill with nitrogen, maintain pressure, and vacuum dry
Before filling the refrigerant, check to ensure that the system has no leaks and remove air and moisture to ensure normal operation of the system.
Step 7: Post warning signs
Post duct system warning signs and indoor unit air outlet size.
Step 8: Fill the refrigerant
Use the refrigerant filling calculator to fill the refrigerant to ensure a reasonable refrigerant filling amount.
Step 9: Test operation
Before the machine is put into use, a test operation should be carried out to ensure that the air conditioner's return air temperature, operating voltage and other indicators are operating normally, and to guide users on the correct usage.
Step 10: Guide the use and complete the delivery
Record each installation process in detail through photos and text, allowing users to fully understand the installation details and also facilitate daily maintenance.
I believe that after reading this article, everyone has a preliminary intuitive understanding of the central air conditioning installation process, but I would like to remind everyone that when installing central air conditioning, you must find a professional central air conditioning installation company, so as to ensure that the central air conditioning is reasonable and correct. The installation can ensure the use experience of central air conditioning after installation and reduce operating costs.
