R134a & R-290 Refrigerant Gases

R134a Refrigerant: An Overview

R134a refrigerant is a ubiquitous refrigerant used in many air conditioning applications. It is often packed in blue cylinders. Because of the nature of R134a’s qualities as an HFC (hydrofluorocarbon) refrigerant, it has minimal ozone depletion potential and has a low greenhouse effect. R134a is an excellent alternative for R12, which has been employed in a variety of applications. Because of its decreased environmental impact, demand for R134a refrigerant and other HFCs will steadily grow. It is now also frequently employed in the air conditioning systems of contemporary automobiles. It is used in the manufacturing industry for plastic foam blowing. It is used as a propellant in the pharmaceutical business. When exposed to the atmosphere, it exists as a gas since the boiling temperature is -14.9°F or -26.1°C

Prominent Features

This refrigerant is not completely compatible with the lubricants and mineral-based refrigerants that are currently utilized in R-12. To use this refrigerant, design adjustments to the condenser and evaporator are required. The system must also be modified with smaller hoses and a 30% increase in control pressure requirements

  • R134a has a high vaporization temperature.
  • R134a is not poisonous, flammable, or corrosive.
  • It has an auto-ignition temperature of 1418 degrees Fahrenheit (770 degrees Celsius).
  • R134a has a critical temperature of 252 degrees Fahrenheit or 122 degrees Celsius.
  • Because R134a has a boiling point of -15.34 degrees Fahrenheit or -26.3 degrees Celsius, it exists in the form of a gas when exposed to the atmosphere. This is a desirable attribute since a refrigerant’s boiling point should be lower than the target temperature.
  • It is 0.11 percent by weight soluble in water at 77 degrees Fahrenheit or 25 degrees Celsius.
  • Because R134a has no Ozone layer depleting qualities, it became popular as a perfect substitute for dichlorodifluoromethane (R-12), which was known to deplete the Ozone layer.
  • R134a has a low acidification potential.
  • In liquid form, it has a modest density.
  • Light blue is the generally recognized cylinder color designation for R134a refrigerant

Detecting Leaks

When you suspect an R-134a leak in your air conditioning system, one of the five procedures listed below can be used to identify it. The easiest and most cost-effective technique is to use soap solution. Workshops may employ more advanced technology to do this.

  • Halogen Selective Detectors
  • Fluorescent Dyes
  • Electronic Leak Detectors
  • Soap Solution
  • Ultrasonic Leak Detectors

R290 Refrigerant: An Overview

R290 is a propane refrigerant that is utilized in a variety of commercial refrigeration and air conditioning systems. It is a very pure, non-toxic propane with an extremely low GWP and no ozone-depleting properties. For these reasons, it is also the Environmental Protection Agency’s (EPA) approved hydrocarbon alternative and can assist businesses in meeting their corporate sustainability goals.

It is not only ecologically friendly, but it is also very efficient, which can result in energy savings during the unit’s lifespan. One research found that a combination of R290 and R600a (both HFCs) increased efficiency in household units by 28.5 percent.

Compatibility with other components is excellent

Another significant benefit is that R290 may be released directly into the atmosphere without the requirement for recapture and recycling. This removes the requirement for technicians to invest in and transport expensive tanks and equipment that were previously required for servicing older systems that used R134 or R404.

Prominent Features

R290 units are totally sealed and self-contained while in normal operation, thus there is almost little possibility of leakage (which is not the case with traditional refrigeration systems with service valves).

There are no ignition sources in contact with the refrigerant. According to a recent study, the use of R290 refrigerants in ice cream freezers increases the danger of fire by 0.001% over a comparable equipment.

An ice merchandiser contains just 115-150g (a maximum of 5.29 oz) of R290, whereas a typical unit would require up to 16 oz of HFC refrigerant. Consider that most grocery shops, petrol stations, and convenience stores maintain dozens of propane tanks for BBQ grills outside their establishments.

These tanks are generally 4.5 gallons in size and store around 20 pounds of propane. An R290 contains around 2% of the propane that a single barbeque propane tank does.
