The Air-Conditioning, Heating, and Refrigeration Institute (AHRI) announced that it applauds the agreement reached in Kigali, Rwanda, by the Parties to the Montreal Protocol to include HFC refrigerants under the treaty.
AHRI Guideline N previously stipulated that specific paint colors be used for refrigerant containers as an additional means of refrigerant identification. However, with the increasing number of refrigerants approved for use, there was concern over the potential misidentification of similarly colored containers.
One method of head-pressure control during low ambient conditions is to use a mechanical hold-back or flooding valve located at the outlet of the condenser to hold back or flood liquid refrigerant in the condenser. This valve is often referred to as an open on rise of inlet (ORI) valve because it will start to throttle open on a rise in condenser pressure.
Despite the long-term energy savings and environmental benefits natural refrigerant systems offer, their higher upfront costs remain a primary barrier to retailers’ widespread adoption of these technologies.
ASHRAE, with the consensus of the American National Standards Institute (ANSI), has designated Bluon Energy’s TdX 20 refrigerant as an approved standard to refrigerant blends under Standard 34-2013. TdX 20 has been given the designation of R-458A.
The U.S. Environmental Protection Agency (EPA) has recognized 13 companies in the supermarket industry for their achievements reducing emissions of refrigerants. EPA said the awardees are preventing refrigerant leaks, transitioning to climate-friendly refrigerants, and using advanced refrigeration technologies.
Hillphoenix announced it has earned the 2015-16 Store Certification Excellence award from EPA’s GreenChill Program. The award recognizes the manufacturer that has installed more advanced refrigeration systems in GreenChill-certified stores than any other manufacturer in the past year.
The Air-Conditioning, Heating, and Refrigeration Institute (AHRI) today expressed disappointment at the decision of the U.S. Environmental Protection Agency (EPA) to decline to extend the proposed effective date of the status change of certain refrigerants used in liquid chillers under its SNAP program.
This recovery machine has horizontally opposing twin cylinders and twin condensers. A permanently lubricated, bearing-line crankcase is isolated from the refrigerant, which eliminates bearing contamination.
One common access valve initially used is some type of saddle valve. These valves are convenient and generally easy to install, but they are not usually considered to be a long-term type of valve and generally should not be left on a system permanently.
