Answered: Do I need to replace copper pipes when upgrading to a new air conditioner?

When deciding to invest in a new air conditioner for your space, there are several important factors to consider. One of the things that many people wonder about is whether they need to replace the copper pipes. In this article, Mytour Supermarket will answer whether replacing copper pipes is necessary when upgrading to a new air conditioner.

Do I need to replace copper pipes when upgrading to a new air conditioner?

Copper pipes in air conditioners have the primary function of carrying gas from the condenser to the evaporator and vice versa. This is an indispensable part of the air conditioning system, ensuring efficient operation and optimal cooling performance.

Air conditioner copper pipes ensure stable cooling performance

When installing a new air conditioner, replacing copper pipes is necessary. Each brand and model of air conditioner sets its own standards by the manufacturer. Therefore, to ensure compatibility and operational efficiency of the air conditioner, using suitable copper pipes is extremely important.

Consider retaining only copper pipes used for a maximum of 2 years.

Material: Prioritize pure copper pipes to ensure high durability, rust resistance, and better gas conduction.

Size: Choose copper pipes with appropriate sizes for the air conditioner, following installation recommendations from the manufacturer and coordinating well with existing piping systems.

Ensure longevity and optimal performance of your air conditioner by carefully considering the quality and usage conditions of copper pipes from the manufacturer.

Prioritize reputable brands and clear origins when selecting copper pipes. Adhere to manufacturer instructions to maintain durability and optimal efficiency.

Opt for copper pipes with established brands and transparent origins.

Below are the specifications for copper pipe diameters corresponding to each air conditioner power level:

Here are some key points to consider when installing copper pipes for air conditioners:

- Protecting Copper Pipes and Other Components: Use synthetic tape to tightly wrap all copper pipes, electrical wires, and drainage pipes to protect them from external impacts.

- Pipe Length: Ensure that the length of the pipes does not exceed 15m and is not less than 3m to ensure optimal operation efficiency for the air conditioner and avoid gas blockages.

- Installation Position: Place the outdoor and indoor units at a distance not too far apart to ensure efficient gas flow. For example, a distance of no more than 5m for 1HP and 1.5HP air conditioners, and no more than 10m for 2HP and 2.5HP air conditioners.

You can extend additional copper pipes into the air conditioning system to save costs during installation according to your needs. Doing so brings the following benefits:

- Reducing Leakage and Damage Risks: Over time, copper pipes may leak due to various reasons such as corrosion, oxidation, or impact. Extending additional copper pipes will help minimize these risks and protect the cooling efficiency of the air conditioner.

- Facilitating Movement or Changing Machine Locations: When you want to change the installation location of the air conditioner, extending additional copper pipes will help adjust the pipe length easily and flexibly.

- Cost and Time Saving: By adding extra copper pipes, you can save significant costs during installation or when relocating the air conditioner while still ensuring stable and efficient system operation.

Air conditioner copper pipes can be extended.

Tools Needed: Gas cylinder, oxygen cylinder, welding wire, safety valve, oxygen cylinder gauge, welding torch, welding wire.

Steps to Follow:

- Open the oxygen cylinder first, then open the gas cylinder.

- Check the gas cylinder and oxygen cylinder gauges at 0.5 kg and approximately 0.4 - 0.6 kgf/cm2 respectively.

- Open and adjust the soldering torch valves, then open the oxygen valve first followed by the gas valve.

- Ignite the flame and adjust the welding torch head at an angle of approximately 45 degrees to the surface of the copper pipe for proper flame contact.

- Solder the gas valve first and then lock the oxygen valve to complete.

Note:

- Oxygen tanks are your best friend when it comes to preventing gas mishaps.

- Make sure not to leave any gas unused in the oxygen tank.

- Welding copper pipes requires finesse and experience, so it's best to entrust it to an experienced air conditioner repair technician.

Utilize snug-fitting couplings for copper pipes and apply adhesive to secure the connection tightly.

Note:

- Select appropriate size and type of couplings.

- Consult with experienced air conditioner technicians to ensure the operational efficiency and safety of the air conditioner after pipe connections as well as personal safety.

Replacing copper pipes can ensure the efficiency and durability of the air conditioner, as well as save costs and time during installation and usage. Hopefully, the information provided in this article has helped you gain a better understanding of this issue and make an informed decision when upgrading your air conditioner.
