A demonstration of complex — but ultimately valuable — developments when it comes to supermarket refrigeration is a project conducted by the Oak Ridge National Laboratory (ORNL) and the U.S. Department of Energy (DOE).
This is my last Point of View commentary for The NEWS’ FROSTlines eNewsletter. By the time you read this, I will have been retired for several weeks. FROSTlines was a new venture for The NEWS when it began a few years ago. It was set to focus totally on refrigeration and it would be online only.
Appliance Recycling Centers of America Inc. (ARCA) announced that it has been granted a patent (U.S. Patent No. 8,931,289) covering its systems, methods, and techniques for facilitating the recovery and recycling of refrigerants and oil from air conditioners, refrigerators, freezers, and other appliances that contain refrigerant.
Super Change™ has been developed to allow a fast and easy conversion from R-22 refrigerant or any mineral/alkylbenzene oil system, to any hydrofluorocarbon (HFC) refrigerant including polyolester (POE)-based R-407C and R-410A.
The Manitowoc Co. Inc. announced that its board of directors has approved a plan to pursue a separation of the company’s Cranes and Foodservice businesses into two independent, publicly-traded companies. The Foodservice business includes ice machines and refrigeration equipment.
This article explores some of the new, state-of-the-art, digital, wireless technologies available for measuring system superheat and subcooling. These new tools enable technicians to automate measurements, share data, and save time and money
Proactive HVAC contractors have been working to educate their employees and clients on the inevitable phaseout. And, with the price of R-22 already starting to rise in many areas, educated contractors are finding it easier to convince customers to replace aging R-22 units with newer, more efficient models.
Choosing the correct line size is very important to the overall success of the installation. Incorrectly sized refrigerant lines can lead to system problems, excessive energy consumption, and higher installation and operation costs.
Supermarket owners want refrigeration systems that are energy efficient to hold down costs and pro-environmental to portray political correctness. But, for engineers, contractors, and technicians, that approach may not be that easy when opening a new store or retrofitting an existing location.
