Explanation. R-123 falls under the A1 code group of ASHRAE Standard 34. ASHRAE Standard 34 is a classification system designed to categorize refrigerants based on their toxicity and flammability.
Opteon™ XP30 (R-514A) refrigerant is a non-ozone depleting, low global warming potential (GWP) hydrofluoroolefin (HFO) based replacement for R-123. It is suitable for new and retrofit systems, offering an optimal balance of properties, including high energy efficiency and environmental sustainability.
Type 3 refrigerants are called low-pressure refrigerants as they are used in low-pressure appliances. Type 3 refrigerants include: R-11 (CFC) R-123 (HCFC)
A given refrigerant is classified under specific code groups according to the ASHRAE 34 standard, an internationally recognized standard. The refrigerant R-123 falls under the Group B1 in standard 34. This characterization is primarily based on the toxicity and flammability of the refrigerant.
R-123 at a pressure of 14.7 psia (Or 0 psig in the chart) will boil at approximately 82°Fahrenheit.
Standard 34 describes a shorthand way of naming refrigerants and assigns safety classifications based on toxicity and flammability data, while Standard 15 establishes procedures for operating equipment and systems when using those refrigerants. ASHRAE offers the standards as a set.
Group 3: Refrigerants with a high degree of flammability .
Those whose lower flammability limit when mixed with air is less than 3.5% by volume (V/V).
Type II covers equipment using high-pressure refrigerant (HCFC-22), including residential air conditioners and heat pumps, supermarket refrigeration, and process refrigeration.
Group B Refrigerants: Group B refrigerants are toxic, so users of these need to be more cautious. Some of the refrigerants in Group B are described in more detail below. R-123 is Dichlorotrifluorethane (CHCl2CF3). It is used as a replacement for R-11 (a Group A refrigerant that is a CFC).
R-123 boils at 82.2°F, hence contents may be under pressure. Exercise caution when opening container. If containers have been stored in direct sunlight or heated above the boiling point of the solvent, the container should be cooled to below the boiling point before opening.
R-454B is the newest refrigerant, which will gradually replace R-410A, the refrigerant used in current HVAC manufacturing. R-454B is a blend of R-32, a hydrofluorocarbon (HFC), and R-1234yf a hydrofluoroolefin (HFO). R-454B has a lower GWP than previous refrigerants, meaning it has a much lower climate impact.
The three main flammability classifications are class 1, for refrigerants that do not propagate a flame when tested as per the standard; class 2, for refrigerants of lower flammability; and class 3, for highly flammable refrigerants such as the hydrocarbons.
Two HCFC refrigerants are widely used in commercial cooling: R-123 and R-22. R-123 will be phased out for new HVAC equipment on Jan. 1, 2020; it will continue to be produced for servicing equipment until 2030.
123 for GASES - TOXIC and/or CORROSIVE. TOXIC; may be fatal if inhaled or absorbed through skin. Vapors may be irritating. Contact with gas or liquefied gas may cause burns, severe injury and/or frostbite.
Everything in R is an object. An object is simply a data structure that has some methods and attributes. A class is just a blueprint or a sketch of these objects. It represents the set of properties or methods that are common to all objects of one type.
Class 2 is for refrigerants that, when tested, exhibit flame propagation at 140°F (60°C) and 14.7 psia (101.3 kPa), have a heat of combustion less than 19,000 kJ/kg (8,174 British thermal units BTU/lb), and have a lower flammability limit (LFL) greater than 0.10 kg/m3.
Requirements to Purchase Refrigerant
The following people can generally buy any type of ozone-depleting or substitute refrigerant under this sales restriction: Technicians who have earned the Section 608 Technician Certification.
R22 has been banned due to its high ozone-depleting potential. R22 leaks are highly toxic and can damage the environment and people's health. The use of R22 freon in air conditioning units has been restricted & banned from being used in any new products.
Common examples of high-pressure systems include residential air conditioners, residential heat pumps, supermarket refrigeration systems, rooftop units, and high-pressure chillers. A few examples of high-pressure refrigerants used in Type II systems are: R-22. R-407A. R-407C.
Explanation: ASHRAE Standard 34 is a standard that classifies refrigerants based on their toxicity and flammability. R-123, a refrigerant, falls under the code group A1. R-123 is categorized as A1, indicating that it has low toxicity and no flame propagation.
Physical properties. R-410A is an A1 class non-flammable substance according to ISO 817 & ASHRAE 34. One of its components, R-32, is mildly flammable (AL2), and the other, R-125, is an A1 class substance that suppresses the flammability of R32.
In new chiller production, HFC refrigerants like R-404A and R-410A are prohibited from 1st January 2024. The production of new equipment using R-22 ceased entirely in 2022, and the HCFC phaseout will be completed in 2030.

'Freon' is the brand name for the refrigerants R-12, R-13B1, R-22, R-410A, R-502, and R-503 manufactured by The Chemours Company, and so is not used to label all refrigerants of this type.
