Recently, there has been a lot of talk about natural refrigerants such as CO2 and hydrocarbons gaining a stronger foothold. Yet much of the talk is related to the possible phasedown of HFC production. And currently, while there may be some talk about a possible phasedown, no actual action seems to be taking place.

Improving heat exchanger performance is one part — a critical one — in enhancing the overall system performance in HVACR systems. What is one way to do it?

Superheat is probably the most talked about yet misunderstood technical term used by service technicians in the field. Superheat is a measured value. What can be done with it?

Today more and more systems are incorporating microprocessor controllers into their design. Troubleshooting the operation of these controllers can be a little tricky at times, but if broken down into sections it can be easier to handle.

The expanding applications for ammonia in commercial refrigeration are being demonstrated in several recent projects involving heat pumps. What constitutes one possibility for efficient management of heat energy?

RSES announced Ruth Ann Davis, incoming president of Women in HVACR, as the keynote speaker at the 2012 RSES Annual Conference and HVACR Technology Expo. What will she be addressing?

The AK-PC 781 multifunctional pack controller makes it easy to set up energy-efficient capacity control of refrigeration compressors and condensers with modular hardware and flexible software that extends as system requirements grow or change.

Two new reports that provide detailed studies of refrigerants have recently been released. The research is evaluating how newer refrigerants — ranging from HFC and HFO f-gases to natural refrigerants such as ammonia, CO2, and HCs — stack up against the current crop of popular refrigerants.

Even turkeys need comfort in preparation for … well, you know. There is also a need for refrigeration and freezing. And the folks who prep the birds need comfortable working conditions. To make sure conditions are the best for all concerned, an 80,000-square-foot turkey products plant in Jonesboro, Ark., underwent an overhaul.

During the brewing process, certain temperatures have to be maintained. For the amber nectar to succeed, breweries need refrigeration solutions tailored to their processes and individual requirements.
