Air-Cooled Chillers Built by J.C. Younger with Exceptional Quality

What is an Air-Cooled Chiller?

An air-cooled chiller is basically a large, refrigerated, cooling system that sucks in the ambient air through its compressor grills to circulate around the refrigerant coils removing some of the heat. The heated air is then pushed back out of the unit by condenser cooling fans back into the environment as the refrigerant continues its movement through the system.

Components of the Air-Cooled Chillers and What Happens to the Refrigerant

An air-cooled chiller is basically composed of a compressor, a condenser, condenser cooling fans, expansion valve and an evaporator with a few other smaller, but important components. To help you better understand air-cooled chillers, we have used an educational video as found on YouTube, “Air Cooled Chillers – How do they work?” by The Engineering Mindset.com, Evans, P. (2017, August 14) to help you visualize entire process.

1. The “compressor” is the accelerator that pushes the refrigerant around the cooling system. When the refrigerant leaves the compressor, it is a “high pressured,” and it is an extremely “heated vapor.” As this heated vapor leaves the compressor, it makes its way to “distribution headers” of the condenser and into the condenser coils.

(Special Note: As Evans points out, there are different types of compressors such as a “screw, scroll or reciprocating,” and we will go into further detail when we discuss your specific chiller needs.)

2. A “condenser” houses the coils moving the system’s refrigerant while the sucked in air circulates around these tubes to help begin the cooling process. After passing through the system’s condenser coils, the refrigerant passes into a “collection header.”

At this point, the refrigerant is now a “saturated liquid of high pressure and medium temperature.” (Special Note: Another important point by Evans is that the metal sheets that surround the condenser can be easily damaged.)

3.Condenser cooling fans” push the heated, surface air out of the condenser that circulated and mildly cooled the condenser coils.

As the saturated liquid passes through the collection header, it enters what is known as the “filter drier” that stops any water or oils from passing through that could cause damage to the system.

4. From the filter drier, the saturated liquid passes into an “expansion valve.” At this point, the liquid has changed to a “low pressure and a low-temperature mixture of liquid and vapor.”

5. The “evaporator” is where the liquid-vapor mixture enters and additional heat is absorbed as it passes through the evaporator and eventually back into the compressor as a “saturated vapor with low pressure and low temperature.”

It is in the evaporator where circulating water from the cooling system re-enters to be further cooled down and sent back out to continue supplying the desired cool air.

The Pros and Cons of an Air-Cooled Chiller

1. PRO – Because there are no cooling tower or pumps needed, an air-cooled chiller takes up less space and can be placed outside.

2. PRO – It does not need water.

3. PRO – Easier to operate.

4. PRO – Less maintenance is required because they are built with fewer components.

5. PRO – With today’s designs, air-cooled chillers can return to full capacity quicker than a water-cooled system.

6. CON/PRO – Heat is a byproduct. When heat is not an issue, these units can be a cost-saving addition during winter months when heating can be expensive for a facility. (Special Note: Air-cooled chillers can be placed outside, and we can help determine where is the best place to house one of these chillers.)

7. CON – Energy consumption is higher making air-cooled chillers less efficient, but with advanced components and technology, more robust efficiency is being seen.

8. CON – More noise is produced via the condenser cooling fans.

9. CON – Lifespan may be shorter if placed outside.

The Team at J.C. Younger Can Build You the Most Dependable, Air-Cooled Chiller

With our history dating back to 1956, the JCY team manufactures and re-manufacturers high-quality component, air-cooled chillers. We have air-cooled chiller packages in stock, or we can customize a unit for your application.

If you’re not sure whether you should select an air-cooled chiller versus a water-cooled chiller, let us help guide you on that question. We also manufacture top-of-the-line, water-cooled chillers. We have years of experience, and we will direct you to the best chiller for your commercial or industrial needs.

J.C. Younger offers work that the entire team can be proud to say, “we built that.” It is always our mission to deliver quality chillers and great support so our customers can get their job done. Whatever your application requires, give us a call to get all your questions answered.

We understand it’s a major operational expense, and we are confident you will be completely satisfied with a chiller from the team at J.C. Younger.

SAMUEL EPPEL

General Manager

Sam graduated from Dunwoody College with a degree in HVAC Service, and started out working in the resident side of work. After many years in the residential side of work, Sam took a chance back in 2018 to work in the commercial side of hvac with Jc younger. Since started working with them, Sam has been streamlining Jc younger to make the service side quicker at getting customer back to cooling right away. He always puts the customer needs first, giving them great customer service, and getting them back cooling right away. When Sam is not at work he enjoys hitting up breweries around the area, going up to the cabin, and doing remodeling projects. He also enjoys going out to lake of the woods for some good walleye fishing.In his free time he enjoys taking his grandmother out for meals, fishing and spending time with girlfriend and dog Sara.

SANDY YOUNGER

President

Sandy has been in the background of JCY since a baby, growing up playing on chiller systems in the large 12,000SQFT pole shed JCY stores units in. Sandy started working at a young age doing simple tasks like sweeping, painting, organizing Copper fittings and other small tasks. In 2005 Sandy started his 4 year degree at Dunwoody College and graduated in 2007.

During his schooling their he also started his apprenticeship under his fathers supervision. The training consisted of installs of glycol piping in the field, building first chiller and assisting with Chiller service repairs. In 2006 he started learning the in and outs of breweries, and has been JCY’s brewery specialist since then. A challenge he took on was glycol piping a 30 bbl brewery by him self and completed that task in less than 20 day with 16 hour shifts.
In his free time he enjoys taking his grandmother out for meals, fishing and spending time with girlfriend and dog Sara.
