Evaporative cooling is growing in demand as cooling needs are expanding.

The cooling towers located on the roof of Granite Tower in Denver were meant to last 20 years. But at nearly 40 years, the cooling towers and fluid coolers were well past their life expectancy.

Johnson Controls has been recognized by independent analyst firm Frost & Sullivan with its Best Practices Customer Value Leadership Award for 2022.

Renewable energy enthusiasts now have reason to celebrate: EVAPCO offers a solar-powered evaporative cooling tower. The SUN cooling tower is paired with PV panels to dramatically reduce energy consumption.  

A product round-up of chillers on the market.

Although evaporative cooling is great at saving energy, it does consume some water, but the benefits on energy savings outweigh the water usage, which in some places is a scarce resource.

Polymer elements in cooling towers — or entire towers made of composite materials, like Fiber Reinforced Polymer (FRP) — can reduce the weight by up to 50%.

Creative Composites Group's acquisition of Enduro will add to CCGs suite of manufacturing capabilities and geographic reach.

The city of Phoenix sought an energy-efficient HVAC solution that would restore Phoenix Art Museum’s lost efficiency and improve the indoor climate for the museum’s specialized environment while also contributing to the city’s energy conservation goals.

Chillers use the principles of thermodynamics to remove heat from a conditioned space. But “chiller” is a broad term that encompasses system configurations, refrigeration technologies, and methods of rejecting captured heat. Experts take a closer look.

Michael Daly, chief technology officer, ECM Technologies, offers insights into the HVAC commercial market.

Despite their similar exterior appearance, cooling towers and closed-circuit coolers are very different pieces of equipment with distinct advantages and limitations. This is especially true when determining which option is best suited for a specific cooling application.

The rapid expansion of data centers has raised concerns about their massive energy use and carbon footprint. However, adopting sustainable HVAC solutions can reduce a data center’s environmental impact and energy consumption.

Manufacturers are offering low-GWP refrigerant alternatives, as EPA is proposing a 700 GWP limit for most new comfort cooling chillers starting in 2025.

Constellation’s Offsite Renewables Plus (CORe+) retail power product, combined with Johnson Controls’ commitment to renewables, is supporting the development of two new Welcome Solar renewable energy facilities.

Like many universities across America, the University of Cincinnati faced a major infrastructure challenge: having to operate aging central utility plants with older technology.

In addition to taking up less space, smaller chillers can be more easily installed, weigh less, and pose fewer shipping, rigging, and building-construction challenges. They can also be more energy efficient, with the same or even greater cooling capacity.

By splitting the absorption process into two steps, lithium bromide solution concentrations are lower in the system, enabling lower hot water temperatures within the generator, lower hot water flow rates, and the elimination of crystallization risk within the chiller.

A North Carolina-based community college replaces an aging metal-clad cooling tower with a modern HDPE unit, reducing maintenance spending while increasing efficiency.

Chillers are being used as heat pumps, outfitted with heat-recovery systems, used in building electrification projects, and installed in arrays to cool data centers.

With a double brood of cicadas forecasted to awaken, now is the time to prepare for how to deal with the mess they will leave behind and the potential damage they can do to equipment.

How does a tech know the a/c compressor he or she is diagnosing is actually failed and that the problem is not a crankcase heater, condenser fan, or rubbed out wire?

Technology is redefining how consumers control their homes. That includes everything from lighting to mood music to heating and air conditioning.

While “smart” tools and tablets are becoming more and more common in an HVAC tech’s toolbox, there are still plenty of things an app just can’t do.

Smart tools continue to grow in the HVACR industry, spurring manufacturers to create connected, digital devices that will make work in the field less manual and more automatic.

Taking home the golden honors in the Testing and Monitoring category of this year’s Dealer Design Awards is the T6 Electrical Tester from Fluke Corp. The product, first introduced to the marketplace in September 2017, went through years of research before launching.

The 8 CFM Vacuum Pump from Fieldpiece Instruments earned its place atop the Electronic and Hand Tools category.

Advancements in technology have brought a lot of opportunity to the tool market, with items like reporting, mobile apps, and wireless data transmission.

The device measures pressure, temperature, flow, and other parameters. Five different ranges are available from ±30 inches of water column to ±100 psi.

The TXV also simultaneously controls a set amount of evaporator superheat while, under these same conditions, assuming the range and capacity of the valve is not exceeded.

When servicing a refrigeration system, it is important to accurately determine the true cause of the failure. Misdiagnosing the problem can often create additional system issues for you and the customer.

The Fieldpiece booth commanded a lot of attention on the show floor at this year’s AHR Expo in Atlanta. Those who didn’t have time to wait in line to find out why may be wondering, “What was all the rage about?”

It was a celebration for Yellow Jacket as the company kicked off its 70th anniversary. In a square booth with a large, lit banner, attendees were invited to explore what the company had produced from 1949 to 2019.

Much like subcooling, understanding and calculating superheat can be somewhat difficult for newbie technicians.

Based on hygrometer technology, this product identifies deviations from ambient rh levels, which can cause static hazards at manufacturing sites and discomfort in homes and offices.

One Stop Cooling studies technicians’ readings recorded on service calls. If you do the same, you might be surprised with the mistakes you find.

This product displays the temperature as real images with a resolution of 240 x 320 pixels and infrared images with a resolution of 33 x 33 pixels.

These products work with the Fieldpiece Job Link System App for on-the-go testing and reporting for HVACR electrical tests.

The most important features of electronic measuring devices have been established in customer surveys and are discussed in this article.

Now available with Bluetooth, this product provides users full access to all features of their devices, such as apps and email.

Is it time for our industry to consider using pascals for static pressure measurements? What would the transition from inches of water column to pascals look like and how hard would it be?

RIDGID will select six winners for a VIP experience at its global headquarters.

Technicians have the choice of using either a digital or mechanical manifold gauge. Each one has its benefits and disadvantages, which is why it may pay to own one of each kind.

Here are a few ideas that contractor can use to prime the marketing pump for this holiday.

In the past few years, the thermostat has become a cutting edge electronic. This creates new opportunities for HVAC contractors.

Thermostats are like other pieces of interactive equipment: People are thrilled by each development but move on quickly when the next feature comes along.

It’s the contractor’s job to ensure consumers understand the functionality of smart thermostats without becoming overwhelmed by the features and data.

With a little ingenuity, HVAC contractors could come out on top in the smart homes market for years to come.

The path to temperature control through smart thermostat technology is more involved than many customers realize.
