Are R-134a and R1234yf interchangeable?
The answer is yes, it will. This makes it simple. Service shops can stock one product, PN 702, and use it for any vehicle, whether it uses R-134a or R-1234yf.
Can you use R-134a gauges on R1234yf system?
R134a service equipment and system components are not interchangeable with R1234yf systems unless they meet the relevant SAE standards.
What is R1234ze?
R1234ze is a low Global Warming Potential (GWP) refrigerant, used as a replacement for R134a in medium temperature refrigeration and air-conditioning applications including water chillers.
Is R1234ze flammable?
R-1234ze is non-flammable, in accordance with the ASHRAE standard 34 (ISO 817). However, it may catch fire if it is mixed with pressurised air and is exposed to strong ignition sources. Its safety classification is A2L group L2.
Is 134a oil compatible with 1234yf?
While R-1234yf oils are backwards compatible with R-134a systems, R-134a PAG oils are not compatible with R-1234yf systems.
Is 1234yf flammable?
HFO-1234yf can be described as being “mildly flammable” as measured by standard methodology.
Is R1234ze a HFC?
R1234yf, R1234ze are examples of unsaturated HFCs also known as HFOs (hydrofluoroolefin). The low GWP HFCs are likely to have a significant role in the future, but are typically lower flammable and must be handled according to this.
Is R1234ze an HFO?
The R-1234ze refrigerant gas is an HFO that replaces R-134a in chillers for industrial refrigeration and A/A. As with all HFO refrigerants, it causes no damage to the ozone layer. It has great thermal and chemical stability, low toxicity and is also highly compatible with the majority of materials.
Is R1234ze heavier than air?
The vapours from R-1234ze are heavier than air and may cause asphyxiation by reducing the oxygen in the air being breathed. Protect it from solar rays and avoid exposing it to temperatures over 50 °C. A unique feature of R-1234ze is the fact that it is non-flammable when mixed with air at 30°C below room temperature.
What type of oil is used in a 1234yf system?
PAG 46 oil
The new refrigerant type uses ND-oil 12, also a PAG 46 oil but with additives specifically for the R1234yf type refrigerant.
How much is a pound of 1234yf Freon?
$120 per pound
However, the average current market price of the R1234yf refrigerant is $120 per pound.
What happens if you inhale 1234yf?
May form explosive mixtures with air. Contains gas under pressure; may explode if heated. May cause frostbite. May displace oxygen and cause rapid suffocation.
What happens if you mix R134a and r1234yf?
The mixing of R-134a with R-1234yf will change refrigerant pressure and may result in evaporator freeze-up on pressure control systems, reducing system airflow.
