Refrigerants

The Chemicals and Refrigerant Reclaimers Product Section of AHRI is conducting a survey to determine the needs of the market regarding refrigerant labeling and the current color scheme for refrigerant containers as more refrigerants are approved for use.

In March, the EPA approved several low-GWP hydrocarbon refrigerants for use in refrigeration and air conditioning applications, subject to use conditions. The approval drew a mixture of reactions ranging from support to concern.

He acknowledges the proposed compliance requirements are not feasible and would cause considerable harm, result in economic job losses, and may increase — not decrease — risks to the American public. Whitfield said this opinion was the consensus of the most affected industries, including the air conditioning and refrigeration sectors.

The Testo 549 Digital Manifold AC/Refrigeration System Analyzer fulfills many of the daily requirements in refrigeration contracting. 

If 30 percent of hydrofluorocarbon (HFC) refrigerants are reclaimed for reuse by 2040, approximately 18 billion metric tons of carbon dioxide (CO2) equivalent would be prevented from reaching the atmosphere over the next 25 years, according to a white paper released by EOS Climate.

In medium- and low-temperature refrigeration applications, 1 hp is hardly ever equal to 1 ton of refrigeration. Let’s review a few principles to illustrate this point.

A refrigeration system can be a major draw on electrical energy, so it can be a real benefit when a technician also can make sure the system is operating efficiently. 

These larger refrigeration systems present tremendous opportunities for energy-efficiency improvements that can lead to significant operational savings.

In industrial countries, production and consumption of HFCs should reach 15 percent of their 2013-2015 reference levels by 2035, stated the proposal. Developing countries would have until 2050 to reach the 15 percent level of their 2028-2030 use and consumption reference levels.

In the evolving world of refrigerants, the HVACR industry is preparing for the inclusion of mildly flammable or flammable refrigerants in an increasing number of applications. But the expanded use of these refrigerants won’t happen overnight, as there is a multistep approval process they must undergo to be approved for new applications.
