Two recent refrigerant developments focus on CO2 and HFOs. One relates to CO2 in refrigeration; the other is an announcement of an HFO in air conditioning.
Heatcraft has opened the state-of-the-art Heatcraft Innovation Center. According to the company, “The new center adds value to customer experience showcasing refrigeration solutions for supermarket, foodservice, cold storage, and industrial cooling applications with a high-tech laboratory and training facility.”
In response to the accelerated phaseout of HCFCs, Indianapolis-based refrigerant producer ICOR International has expanded its refrigerant reclamation operations.
Tecumseh Products Co., headquartered in Ann Arbor, Mich., said that it is focusing on increased technical training and support for its network of authorized North American wholesalers with the establishment of Tecumseh University.
Those of a certain age may remember the original editions of the young teen series such as The Hardy Boys and Nancy Drew. Since the early 1970s, the series still around have been updated and condensed. I mention that because in the original series more attention was paid to minor details that made for interesting reading.
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?
