An RV AC heat pump designed for R-22 cannot directly use R-134a, as these refrigerants have different properties and operating requirements. R-22 and R-134a require different types of lubricants and have distinct pressure ranges, which means components like compressors and expansion valves may not function properly if mismatched. Converting a system from R-22 to R-134a typically involves replacing major components to ensure compatibility and efficiency. It is advisable to consult a professional HVAC technician for such conversions.

What is the Refrigerant requirement for 1995 Toyota Avalon R22 or R134?
r134
Can you put R22 in your empty R134 system?
NO ! and Why?
Can you mix r134a freon with r22 in a heat pump?
No
Is r134 compatible with r22?
No, the two cannot be blended.
Is r134 compatible with r22 freon?
No, the two cannot be blended.
Can you mix r22 freon with R410a in a heat pump?
No , they operate at different pressures and are not compatible.
What kind of refrigerant does a Toyota Corolla use?
After 1992- r134A Before 1992- R22 but it need to be retrofitted for R134 if it hasn't been done already. It is ILLEGAL to use R22 in autos.
Will a r134 compressor replace a r22 compressor?
No, an R134a compressor cannot directly replace an R22 compressor due to differences in refrigerant properties and system requirements. R134a and R22 operate at different pressures and have different lubrication needs, so using an R134a compressor in an R22 system could lead to inefficiency or damage. If converting from R22 to R134a, the entire system, including the compressor, evaporator, and condenser, typically needs to be modified or replaced to accommodate the different refrigerant.
How do you determine if charge is correct using R22?
To determine if a refrigerant charge is correct using R22, you would need to measure the suction and discharge pressure and temperature, calculate the superheat and subcooling values, and compare them to the manufacturer's specifications or recommended values for the specific system. Adjust the refrigerant charge if the measurements are outside the acceptable range to ensure optimal system performance.
Can you use R134 instead of R22 in a window ac unit?
Using R134a instead of R22 in a window AC unit is not recommended, as they have different properties and pressure requirements. R22 is a high-pressure refrigerant, while R134a operates at a lower pressure, which can lead to inefficiencies and potential damage to the system. Additionally, the oil compatibility and system design may not support the use of R134a. Always consult a professional or refer to the manufacturer's guidelines before making any refrigerant changes.
Is r600a a replacement for r22?
It is an alternative to mostly banned CFCs (most infamous of which is R22), and to be phased out in the future HFCs (R410a, R134 and similar). That being said the general consensus is that R600a (isobutane) requires compressors/systems specifically designed for it. The most suitable HC or natural refrigerant substitute for R22 is R290, which although shunned by the industry will perfectly replace it with an efficiency increase of about 20% without any retrofitting or other adjustments.
What pressure should you target when adding R22 to a 2 ton 1985 comfortmaker heat pump?
When adding R22 to a 1985 Comfortmaker heat pump, you should target a suction pressure of approximately 25-30 psi and a discharge pressure of around 200-250 psi, depending on the ambient temperature. It's essential to refer to the manufacturer's specifications and ensure the system is properly evacuated and leak-free before charging. Additionally, monitor the system's performance and temperature to achieve optimal efficiency. Always exercise caution and follow safety protocols when handling refrigerants.
