A.G. Coombs issues advice on commercial HVAC refrigerants

A.G. Coombs has developed an update on its suggestions about refrigerant use for commercial HVAC devices.

“As the environment grapples with climbing temperatures prompted by the emission of greenhouse gases, refrigerants are less than renewed scrutiny,” A.G. Coombs claims. “Common refrigerants are labeled as greenhouse gases, which can be hundreds or even a thousand occasions worse from a worldwide warming likely (GWP) vs . the equal quantity of organic refrigerants such as carbon dioxide (CO2).”

The Advisory Be aware is in depth, providing information on the HFC section-down and Montreal Protocol, the condition of the present-day refrigerant marketplace, HFC options, refrigerant traits, and an evaluation of what the section-down usually means for industrial HVAC programs.

Considering the fact that the phase-out of chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs), the most common type of refrigerant accessible in the market today are hydrofluorocarbons (HFCs).

“The important trouble with HFCs crop up from their worldwide warming opportunity,” the be aware advises. “GWP is a physical residence of greenhouse gases, which signifies the propensity of the fuel to entice atmospheric warmth.”

The note goes on to reveal the HFC section-down is a gradual reduction in the optimum volume of HFCs permitted to be imported into Australia.

“The framework of the Australian authorities HFC stage-down is geared towards restricting the importation of HFC gases, with a watch of encouraging marketplace forces to ascertain the best remedy,” the be aware says. “As this sort of, it is helpful to notice the sector to see what variations, developments and innovations are using place.”

So, what does this suggest for commercial HVAC techniques?

“With the section-down of HFC refrigerants, there will be lessened provide, and this is most likely to consequence in growing price tag of the gas around time,” states A.G. Coombs. “This has been observed with an raising cost of R134a more than the previous 5 a long time.”

The be aware advises maintaining an exact asset schedule of all incorporating HFC refrigerants, talking with mechanical servicing providers to detect any HFC plant functioning inefficiently, getting ready a refrigerant administration approach, reviewing chiller plant substitute approaches, and thing to consider of systems that can provide both of those cooling and heating at the exact time to leverage price efficiencies.

“It must be famous that the Kigali settlement is a period-down and not a period-out, which means there are no HFC production bans as there had been with hydrochlorofluorocarbons (HCFCs) these as R22,” the observe states. “However, it is however significant to take into consideration the range of the refrigerants in any new and alternative plant.”
