Ongoing refrigerant developments and efficiency regulations have the attention of many in the compressor industry.

The weird thing about compressor problems is that — well, it’s usually not the compressor.

It’s probably something else. Can the technician on the job today figure out what that something else is? That could determine whether it’s a successful call and a happy customer or a visit that appears successful until the new compressor fails (after several additional costs and a lot of frustration).

How do refrigeration products continue to spread through everyday life, and what could be in store for the grocery sector in particular?

In HVAC, we rarely need to have a deep understanding of electrical design. But there are a few cases where a little understanding can go a long way in identifying issues before they cause trouble, and that is the intent of this short article.

Every HVAC manufacturer, distributor, and contractor is aware of the growing labor shortage within the skilled trades industries. Most have been working to combat the shortage by getting creative in recruitment efforts — much like Daikin Applied did at the 2019 AHR Expo.

The architecture of the product is well-suited for applications utilizing low-density gas due to its high displacement density and low cost to manufacture.

To obtain the heat content (enthalpy), it would be necessary to know both the pressure and temperature at this point and then use a thermal dynamic superheat table for this specific refrigerant.

Many single-phase compressors require a start capacitor to assist in starting the motor. These capacitors will occasionally fail, causing a compressor to fail to start.

From the introduction of scroll technology to the onset of variable speed, HVACR compressors have come a long way. Unequivocally, these aren’t your grandfather’s compressors.

Danfoss had a fruitful and satisfying 2018 AHR Expo. Not only was its Turbocor® TTH/TGH High Lift Compressor named the winner of the 2018 AHR Expo Innovation Awards in the Green Building category, the company also took home the coveted Product of the Year award.
