The case can be made that recovery and reclamation begins with keeping refrigerants in the system where they belong; refrigerant that leaks out into the atmosphere is never going to be recovered or reclaimed.
Receives J&E Hall Gold Medal Award for work with chillers, heat pumps
April 4, 2017
Thomas Watson, a former ASHRAE president and retired chief engineer at Daikin Applied, recently received the Institute of Refrigeration’s (IOR) J&E Hall Gold Medal Award for his ground-breaking work to improve the efficiency of chillers and industrial heat pumps.
New cold chain storage equipment optimizes airport for shipping perishable goods
April 4, 2017
Dallas Fort Worth International (DFW) Airport is installing a cold chain facility intended to provide cargo and logistics customers with enhanced opportunities to ship perishable items. Expected to be operational this summer, the state-of-the-art transfer facility will give DFW the ability to precisely control warehousing temperatures for customers shipping pharmaceuticals, flowers, and fresh foods. The facility will be operated by AirLogistix USA.
Springtime means many different things to many different people: Love in the air; baseball, golf, and grilling; shorts and sunscreen; a rebirth; a triumph of the dogged determination of life to begin anew after winter. Or, for those in the refrigeration industry, spring of 2017 means just three more cooling seasons until the only R-22 on the market will be what’s available through reclaimers or in individual inventories (a.k.a. stockpiles).
The right attitude and a willingness to learn can make tough jobs easier
April 3, 2017
There are times when determining the cause of a system problem can be quite difficult. Those are the times when a “master” technician will shine above the others. There are many qualities that allow technicians to be very good troubleshooters. One of these qualities is the attitude they take to the job and how they approach looking for the problem.
Carbon dioxide (CO2) as a refrigerant is gaining increasing industry acceptance in commercial and industrial refrigeration systems in North America, according to a survey conducted by Danfoss. The survey also identified barriers to greater CO2 use in refrigeration.
Researchers must look beyond nonflammable chemicals
April 3, 2017
NIST’s study, entitled “Limited options for low-global warming potential [GWP] refrigerants,” focused on residential and small-commercial single-package and split air conditioning systems, but the authors said their conclusions also generally apply to room air conditioning units and other refrigeration and heat-pump systems currently using common, ozone-depleting refrigerants such as R-410A or R-22, which are still used in some developing countries today. “The takeaway is there is no perfect, easy replacement for current refrigerants,” NIST chemical engineer Mark McLinden said.
The easybend kit consists of four color-coded, industrial-grade, solid, polyethylene mandrel diameters. It is 13 feet long and fits quickly, but snugly, into soft copper lineset tubing sizes of ¼-, 3/8-, ½-, and 5/8-inch.
