4 Reasons For Condensation On Aircon Trunking & How To Fix

Condensation on Aircon trunking

Have you started to notice black patches or mold on the aircon trunking? These are early signs of condensation on the trunking which can eventually lead to water dripping, if not fixed.

AC trunking refers to the network of ducts, pipes, and channels that distribute cooled or heated air throughout a building. In this article, we bring to you the reasons behind condensation on AC trunking and explore potential solutions to this fix the problem.

1. Poor Insulation

Insufficient or damaged insulation on AC trunking can lead to temperature imbalances, fostering condensation. Insulation acts as a barrier, preventing the transfer of heat between duct surfaces and surrounding air.

Solution: Regularly inspect AC trunking insulation, repairing or replacing damaged sections as needed. Upgrading to higher-grade insulation enhances the effectiveness of the barrier, minimizing condensation risks.

2. Air Leaks

Air leaks in the ductwork contribute to condensation by allowing warm, humid air to enter and contact cooler surfaces. Leaks can also compromise insulation efficiency.

Solution: Promptly seal any air leaks in AC ducts. Regular inspections and maintenance help identify and address leaks, preserving the system’s integrity and preventing condensation issues.

3. Improper Installation Of Trunk

If the aircon trunks are not installed correctly, water from your air conditioner might drip into the trunk, causing it to get wet and form condensation. There should not be any loose connection between the aircon unit and the trunk from water can slip through.

Solution: In most cases the solution is to re-install the trunks and ensure that the trunks correctly fit and align with the aircon units.

4. Trap Floor Blockage

A floor trap blockage can contribute to condensation on AC trunking through a combination of factors related to restricted drainage and increased humidity.

A floor trap is designed to allow the drainage of water. When the floor trap is blocked, water drainage becomes impeded. If your air conditioning unit produces condensate (water formed during the cooling process), a blocked floor trap can prevent the proper drainage of this water and hence cause water leakage.

Solution: Engage a professional aircon technician to clear the blockage in the floor trap, ensuring proper drainage.

Final Thoughts

AC trunking, comprising the network of ducts and channels, plays a vital role in the functioning of air conditioning systems. Understanding and addressing condensation issues through regular inspection, maintenance, and the use of quality insulation materials are crucial steps in ensuring the efficiency and longevity of AC systems. By implementing the suggested solutions, users can maintain a comfortable and well-regulated indoor environment, free from condensation-related challenges.

Foam Vs Rubber Insulation? Which Is Good For Aircon Pipe

Foam insulation for aircon pipes

Various types of aircon pipe insulation are available for residential and industrial use, each with its own set of advantages and disadvantages depending on the application. To simplify the selection process and ensure optimal system performance in the long run, it is crucial to consider the requirements of the premises where the insulation is being installed.

This article specifically focuses on closed-cell pipe insulation, comparing flexible rubber with foam pipe insulation and exploring which option is better suited for different applications. Both rubber and foam pipe insulations have closed-cell structures that effectively manage condensation and thermal exchange on cold piping systems.

Rubber Insulation

Flexible elastomeric closed-cell foam pipe insulation, commonly known as rubber, is composed of synthetic rubber. The two primary formulations available are nitrile butadiene rubber with PVC (NBR/PVC) and EPDM (Ethylene Propylene Diene Monomer). The industry standard is ASTM C 534. A comparison between NBR/PVC and EPDM is provided in a later section.

Foam Insulation

Alternative to rubber insulation is foam insulation also known as polyethylene, polyolefin, poly, or PE. Foam plastic pipe insulation is commonly used in residential and light commercial piping systems, following the industry standard ASTM C 1427.

Rubber Vs Foam Insulation

Choosing between foam rubber and foam plastic depends on factors such as thermal efficiency, continuous service temperature, fire safety, density, and cost. Foam rubber typically offers a lower thermal conductivity (favorable K-value) than foam plastic. The upper continuous service temperature varies, with foam plastic at 200°F, NBR/PVC foam rubber at 220℉, and EPDM foam rubber at 257℉.

Fire safety is a critical consideration, with foam rubber generally passing ASTM E 84 or UL 723 tests, while foam plastic may exhibit less predictable behavior, especially at greater thicknesses.

Considering factors like density, cost, and performance characteristics, foam plastic is often less expensive than rubber.

When comparing rubber to foam plastic pipe insulation, rubber is generally preferred for commercial and industrial applications due to its lower thermal conductivity, higher continuous operating temperature, and more predictable fire behavior. Rubber is likely to meet the building owner’s project requirements more comprehensively.
