The Science of Cool: How Cooling Coils Revolutionize Summertime Comfort

Cooling Coils, the Unsung Heroes of Summer

Coils are essential for maintaining cooler temperatures in a variety of industries. Whether it’s keeping beer cold, preserving food, controlling computer systems in data centers, or producing delicious ice cream – coils play a vital role in making all these possible! That’s why when you take a sip of that cool beverage or enjoy your favorite ice cream flavor, you can thank the coil technology that made it happen.

There are several different types of cooling coils, each of which is designed for specific applications, such as residential or commercial HVAC systems. All of these are designed to help you keep your environment comfortable and cool, no matter the season. Let’s take a closer look at each of the fundamental types of cooling coils.

Chilled Water Coils

Chilled water coils are typically used in large commercial HVAC systems where chilled water is circulated to cool the air. These coils transfer heat between the chilled water and the air, cooling down the air before it is distributed into the building. By circulating this cooled air throughout a building, chilled water coils are able to regulate the temperature indoors, even when outside temperatures become unbearable.

Do you know the main difference between a hot water coil and a chilled water coil? Usually, hot water coils are small (1-2 rows) and chilled water coils are larger (3-12) rows deep.

Condenser Coils

Condenser coils are located in the outdoor section of the HVAC system. They receive the high-pressure, high-temperature refrigerant vapor from the compressor. As the refrigerant flows through the condenser coils, it releases heat to the outdoor air, causing it to condense back into a liquid state. This liquid then moves back into the indoor system, repeating the cooling cycle.

DX (Direct Expansion) / Evaporator Coils

DX (Direct Expansion) coils are also known as evaporator coils. Evaporator coils use refrigerant, instead of water, to remove heat from the air. As hot air blows across the coil, the liquid refrigerant inside will evaporate into a gas. This phase change allows the refrigerant to absorb heat from the air and send cool dehumidified air to the space.

So, the next time you step into a comfortably cool environment on a sweltering summer day, remember the remarkable work of chilled water coils, direct expansion coils, and evaporator coils, ensuring that you can enjoy a cool oasis no matter how high the mercury rises.

Recognizing the Signs: When You Should Replace Commercial HVAC Coils

Maintaining the right temperature in your facility is essential for ensuring the comfort and safety of those living or working within. That’s why it’s important to have a properly functioning HVAC system with coils that are regularly inspected, serviced and replaced when necessary.

Unfortunately, coils can fail prematurely due to freeze damage or other factors such as incorrect selection, corrosion or lack of maintenance. Understanding the signs that indicate when it’s time to replace or repair your HVAC coils is essential for your facility.

In this article, we’ll provide you with an overview of indicators that signal it might be time to replace or repair your HVAC coils so you can keep your building comfortable and safe at all times. Let’s get started!

Reduced System Efficiency

A decrease in system efficiency is often the first sign that your HVAC coils may need to be replaced or repaired. If you notice an increase in energy consumption without significant changes in usage patterns, this can indicate a problem with your coils. In addition, if any areas of your building are not being adequately heated or cooled, this could also indicate a problem with your coils.

Frequent Breakdowns and Repairs

If you’re experiencing frequent breakdowns and repairs with your HVAC system, it’s time to evaluate whether coil replacement or repair is the most cost-effective solution. The costs associated with regular repairs can add up quickly, making it more financially sensible to invest in replacing the coils entirely.

Be sure to evaluate the cost of repairs versus replacement before making your decision. Doing so will help ensure that you are investing in the most suitable solution for your facility’s needs.

Visible Coil Damage or Corrosion

Corrosion is another indicator that your coils may need to be replaced or repaired. If you notice any signs of corrosion, it’s important to address the issue as soon as possible. Corroded coils can cause significant problems if left unchecked, including reduced efficiency, system damage and potentially even health and safety risks.

If you notice any physical damage, including cracks, leaks, bulged or split return bends, these are strong indicators that the coil should be replaced. Freeze damage is one of the most common reasons for premature coil failure, it occurs when water turns into ice, increasing its volume and creating pressure on the coil. This pressure is strong enough to rupture the coil, resulting in a bulged and split return bend or fin pack. By adding Freeze Block technology to your coils when replacing, you can reduce the risk of freeze damage and avoid costly repairs or replacements. It is important to check your HVAC system on a regular PM schedule for any signs of visible damage or corrosion in order to avoid costly repair fees later on.

Poor Airflow

If you notice a decrease in airflow or an overall decrease in circulation, this could be a result of clogged fins on the coil. This can lead to uneven temperatures within the building, as well as an uncomfortable environment due to inadequate air movement.Dirty Mold HVAC Coil

Properly cleaning coils is essential for maintaining their efficiency and prolonging their lifespan. Additionally, the use of UV systems can help reduce microorganism growth that can lead to increased dirt and dust buildup on the coil surface, negatively impacting air quality within your facility. By installing a UV system along with regular maintenance on your coils, you will be able to improve the overall airflow and reduce the need for frequent coil repairs or replacements. This in turn will help you save on energy costs, maintain comfortable temperatures and ensure that your equipment is running at optimal levels.

Age of Existing Coils

If your coils are older than 10 years, it’s time to consider replacing them. Efficiency can drop by 30% over time. This is because, as time passes your HVAC coils will naturally weaken due to constant expansion and contraction. This can lead to a decrease in the coil’s performance and an overall reduction in system efficiency.

Reduce HVAC Coil Cleaning and Increase System Performance with UVGI

With UV-C Disinfection, you’ll be able to breathe easily knowing that your coils are clean and free of harmful germs. You’ll also save money on maintenance costs and won’t have to worry about a dirty coil causing problems with your HVAC system or energy costs.

Dirty Coils = Higher Maintenance & Energy Costs

HVAC coils, like all parts of a system, need to be clean for optimal performance. As the coils become dirtier with dust, pollen, mold spores, mildew, and other particles – the ability for the coil to transfer heat decreases. The decrease in efficiency can cost you more in energy and money, because the system has to work harder to reach desired temperatures.

When coils are left uncleaned, the dust and other contaminants that accumulate on them can form into a thick layer of grime. This reduces efficiency, increases energy costs, and causes breakdowns more frequently.

Commercial HVAC coils become dirty very quickly due to the high volume of air that passes through them. Dust and debris can settle on the coils, reducing their efficiency, leading to higher energy costs. Over time, airborne germs such as mold and bacteria can build up on the coils, further reducing performance and potentially causing health issues for building occupants.

Regular coil cleaning is necessary to maintain optimal performance and energy efficiency but can be expensive and time-consuming.

Why Clean HVAC Coils are Key

1. Helps the System to Run More Efficiently

One of the primary reasons why it’s important to clean the coils in your commercial HVAC system is that it helps the system to run more efficiently.

Regular cleaning will help to ensure that your system is running as efficiently as possible.

2. Helps to Prolong the Life of the System

Another reason why cleaning coils is important is that it helps to prolong the life of the system. When coils can begin to corrode, which can shorten the lifespan of your HVAC system. By keeping them clean, you can help to ensure that your system lasts for many years.

3. Reduces Repair and Maintenance Costs

In addition to helping your HVAC system run more efficiently and last longer, regular coil cleaning can also help to reduce repair and maintenance costs. When coils are clogged, they are more likely to break down, which can lead to expensive repairs. By keeping them clean, you can avoid these costly repairs.

4. Improves Indoor Air Quality

Another benefit of clean coils is that it improves indoor air quality. When coils collect dirt and debris, they can release these particles into the air, which can cause respiratory problems for people who are exposed to them. Regular cleaning will help to remove these particles from the air and improve the quality of the air inside your building.

5. Reduces Allergens in the Air

In addition to improving indoor air quality, regular coil cleaning can also help to reduce allergens in the air. Coil cleaning removes pollen, dust mites, and other allergens from the coils, which helps to improve air quality for people who suffer from allergies or asthma

Traditional Coil Cleaning Methods

Traditional coil cleaning involves the use of harsh chemicals and abrasive methods to remove dust, debris, and microorganisms from commercial HVAC coils. This can be a time-consuming process that must be done frequently in order to maintain optimal performance and energy efficiency. Unfortunately, due to reduced manpower caused by budget cuts or staff shortages, this regular maintenance may not be done as often as necessary, leading to decreased performance and increased energy costs.

UV-C Disinfection – The Easier, More Efficient Solution for HVAC Coils

Visually inspecting your coils may not be enough to detect when they need cleaning. That’s why UVGI disinfection is helping facilities keep their coils clean and running optimally.

 

UV-C light is a type of ultraviolet light that has been scientifically proven to kill germs, bacteria, and other microorganisms on contact. It can be used in an HVAC system to reduce the spread of airborne germs, and keep the coils running clean and efficiently.

Benefits of UV-C

Frequently Asked Questions

Does UV Cleaning Really Work?

Yes, ultraviolet (UV) cleaning is a proven technology for disinfecting commercial HVAC systems. UV cleaning uses intense light from an ultraviolet lamp to destroy bacteria, mold and other contaminants that can build up in air ducts.

How Does UV Disinfection Work?

UV disinfection works by exposing contaminants in an HVAC system to intense light from a UV lamp. The ultraviolet light breaks down the structure of the bacteria, viruses and other microorganisms, killing them on contact. This helps reduce the spread of airborne germs and ensures that coils in an HVAC system remain free of contaminants and running optimally.

Does UV-C Kill Mold on Coils?

Yes, UV-C light is very effective at killing mold as long as a system is measured and designed properly. UV-C light is able to penetrate the coil surface and kill mold spores such as aspergillus niger (black mold) that may be present on the surface, helping to keep HVAC coils clean and free of contaminants.

When using a Fresh Aire UV-C bulb, the germ-killing effect starts almost immediately – with about 90% of surface microbes being sterilized within the first few minutes. After the first 24 hours, this number increases to about 99.99%.

UV-C Lights for HVAC

How does UV-C compare to bipolar ionization?

Ultraviolet C (UV-C) is an established air disinfection technology that can be used to inactivate viruses, such as SARS-2-CoV, the virus that causes COVID-19. When compared to bipolar ionization, UV-C has been studied for more than a century and there are some significant differences between the two technologies.

The primary difference between UV-C and bipolar ionization is how each technology works. Bipolar Ionization uses electrical charges to create ions that attach to tiny particles in the air and either kill them or make them heavier so they’ll settle out on surfaces. On the other hand, UV-C light breaks down DNA strands of viruses and other microorganisms, rendering them inactive.

In simple terms, bipolar ionization acts like a trap, while UV-C actively kills microorganisms and contaminants.

How often do UV-C bulbs need to be replaced?

Although lamps may still emit visible light even after their designated 1 or 2-year lifespan, their UV effectiveness will decrease over time. This is why it is important to replace your amplifier after its designated lifetime – as the lamp’s UV output will no longer be as effective at killing germs and viruses in the environment.
