Which type of refrigerant does not deplete the ozone layer?
HFC-134a
Currently, most MVACs use HFC-134a (also known as R-134a), a refrigerant that does not deplete the ozone layer, but has a GWP that is approximately 1,400 times greater than CO2.
What is R717 refrigerant?
R717 is refrigerant grade high purity ammonia (NH3). The product typically is 99.98% pure with minimal levels of moisture and other impurities (< 200 ppm and < 5 ppm oil), making it ideal for use in all types of refrigeration systems, especially in the air conditioning industry. Ammonia 3.8 (99,98%). Max 200 ppm H2O.
Is R-134A ozone depleting?
Also, R-134a is a very safe refrigerant with an ASHRAE safety classification of A1. This means it is not flammable and has very low toxicity levels. Because HFC-134a has no chlorine in its molecule, it has a zero ozone-depletion potential (ODP) and doesn’t deplete the stratospheric ozone layer.
Is R-410A ozone depleting?
R-410A will not damage the ozone. R-410A has a significantly higher vapor pressure than R-22. The condensing pressure of R-410A at standard conditions for water-cooled chillers is about 340 psi and approximately 390 psi for air-cooled chillers.
What is 408A refrigerant used for?
R-408A is a retrofit solution for medium and low temperature refrigeration systems that are currently using R-502. R-408A should not be mixed with R-502 or used to top off the charge of an existing system operating on R-502. R-408A is not intended for use in new equipment.
What is R502 refrigerant used for?
Before its phaseout in 1995, it was used in low temperature refrigeration (the evaporator pressure stays out of vacuum down to -40°F). R-502 offered lower discharge temperature and improved capacity compared to R-22….Product Information.
| Part Number | Product Description |
|---|---|
| 30R502 | 30 LB. CYLINDER |
| 125R502 | 125 LB. CYLINDER |
What is R 744 refrigerant?
The term R744 refers to CO2 when it is used as natural refrigerant in the refrigeration and air conditioning industry. R744 CO2 has excellent thermodynamic properties and has significant advantages compared to classical and other alternative refrigerants.
What refrigerant is replacing R-134a?
There are three refrigerants that can be used to replace R-134a: R-1234yf, R-152a, and R-744. More on these replacements later.
Is r407c an ozone depleting substance?
Hydrochlorofluorocarbons (HCFCs) are ozone depleting substances (ODS) controlled by the Montreal Protocol on Substances that Deplete the Ozone Layer that are widely used in refrigeration and air conditioning, foam blowing and solvent applications.
Which refrigerant is ozone friendly?
An Ozone Friendly Refrigerant – R-410A R-22 is found in many household appliances including air-conditioning systems and refrigerators. HCFC was developed as a replacement for the popular CFC since it was considered safer, not toxic and non-corrosive.
Is R32 refrigerant eco friendly?
R32 refrigerant represents innovation in every way. It is an excellent heat transfer medium which leads to greater energy efficiency and cost effectiveness. R32 refrigerant also has low global warming potential, hence it’s friendlier to the environment.
What is the best refrigerant?
Although there are various types of refrigerants, R-32 is a new refrigerant currently receiving the most interest. Because R-32 efficiently conveys heat, it can reduce electricity consumption up to approximately 10% compared to that of air conditioners using refrigerant R-22.
What is R23 refrigerant?
R23 is a HFC, used as a replacement for R13 and R503 in very low temperature refrigeration. It is also used as a clean fire suppressant as a replacement for Halon 1301.
What is 409A Freon used for?
R-409A is formulated to closely resemble the properties of R-12. Applications include many medium temperature refrigeration systems, vending machines, refrigerators, positive displacement chillers, humidifiers, and other systems using R-12 or R-500. R-409A has properties and performance similar to R-12 and R-500.
What is R507 refrigerant?
R507 is an HFC blend, used as a replacement for R502 and R22 in low and medium temperature refrigeration. With a Global Warming Potential (GWP) of 3985, R507 is under similar scrutiny to R404A.
What is refrigerant 409A used for?
It can be used in medium- and low-temperature positive displacement equipment. Used as a retrofit for R-12 in stationary positive displacement air-conditioning (AC) and refrigeration systems, Freon™ 409A works in: Walk-in coolers. Beverage dispensers.
Is R502 still available?
Since the phase-out of R-502 in 1995, service quantities are still available through recovery and reclaim operations.
