What refrigerants has the lowest boiling temperatures at atmospheric pressure R-12 R-22 R-134a R-502?
This is R-502 with a boiling point at -45 0C.
What does R-134A stand for?
In chemistry, this chemical compound, R-134A is the symbol for tetrafluoroethane. Tetrafluoroethane can be used as a solvent in organic chemistry.
When checking a cylinder of recycled HFC-134a for non-condensable gasses at 70degrees the pressure should not exceed what psig?
When checking a cylinder of recycled HFC-134a for non-condensable gases at 70 degrees Fahrenheit, the pressure should not exceed 10 psig. This limit ensures that the cylinder does not contain high levels of non-condensable gases, which can affect system performance and efficiency. High pressures indicate a high concentration of non-condensable gases, requiring proper evacuation before use.
What is an example of CFC refrigerant?
The example of CFC is R-12. It is being used as a refrigerant.
What is the standard condensing and evaporating temperature of refrigerant 134a?
The standard condensing temperature of refrigerant 134a is around 130°F (54.4°C), and the standard evaporating temperature is around -15°F (-26.1°C).
What is the running pressure of car airconditioning suction and discharge pressure using 134a refrigerant when operating?
35suction pressure in 1000 rfm
What is the correct suction pressure whin charging a chiller using refrigerant 134a?
926.5
What is the correct suction pressure when charging a freezer using Refrigerant 134a?
Negative 30 psi should do it.
What is the required dischage pressure of R134a?
R-134A shares the same basic operating characteristics as R-12. There is no "required" discharge pressure. Most manufacturers of equipment use 100deg.F as a standard for condensing temperature, in rating the capacity of their units. Discharge pressure is dependent on quantity of charge, ambient outside temperature (condensing pressure), and suction pressure. These factors all control discharge pressure in a normally operating system. Throw in a compressor with valve leakage or piston ring/ seal issues and it gets more complicated. If this is an automotive related question, read the can. lc
What are the pressures readings for 134a on a cooler?
22 to 23 suction 125 to 150 on head
Where are the ports front and rear on a 1997 gm suburban so you can refill the freon what freon is used?
Virtually all vehicles since 1994 use refrigerant r-134a. On a 97 Suburban, the suction (low pressure) and discharge (high pressure) ports are located on top of the compressor. Refrigerant is added to the low pressure side. It is attached to the larger refrigerant piping and hose which runs to the accumulator-drier at the firewall. The smaller high pressure pipe attaches to the condenser located in front of the radiator. Do NOT attach a refrigerant can to the high pressure line.
Freon pressure for 1993 Aerostar with R-134a?
The 1993 Aerostar does not use R-134a. It uses R-12.
What should the pressure be when putting R-134a to recharge air conditioner?
45-60. Anything higher could indicate a bigger problem. A 134a system is similar to a R12 system in that you have a chart listing temperatures and pressures, with 134a running slightly higher. That said, you need both suction and discharge pressures and outside/inside temperatures, along with engine speed to let someone diagnose your system. You also need to make sure that your compressor and all other parts - relays, fans, hoses not plugged by collapsed inner liners, etc. are functioning properly before "adding a can" of 134a. You can seriously overcharge if you don't know what you're doing. Best solution if everything is functioning properly, is to have a qualified mechanic empty the system, pull a vacuum and re-install the correct charge (weight of 134a). This is different from make to make, but is critical. A 134a system does not have the"bubble gauge" as a R12 system does, and it is easy to get under or over in the charge. Your mechanic will weigh in the correct number of cans for proper operation. when all else fails, try 34psi on the suction gauge. this is real close to where you need to be.

What are operating pressures for r-134 a?
The operating pressures for R-134a (tetrafluoroethane) vary depending on the application and temperature. Generally, at a typical evaporating temperature of around 40°F (4°C), the suction pressure is approximately 30-35 psi, while the corresponding discharge pressure at a condensing temperature of around 100°F (38°C) can be around 200-220 psi. It's important to consult specific refrigeration or air conditioning system guidelines for precise pressure values, as they can differ based on system design and operating conditions.
What is the density of R134A?
Density of R-134a changes with respect to temperature and pressure.
How do you read r-134a gauge?
To read an R-134a gauge, first ensure that the gauge is properly connected to the refrigerant system. The gauge typically has two parts: the low-pressure side (blue) and the high-pressure side (red). For the low-pressure side, read the pressure indicated when the system is running; it should be between 25-45 psi for normal operation. For the high-pressure side, readings of 150-250 psi are typical, depending on ambient temperature and system conditions. Always refer to specific manufacturer guidelines for accurate interpretation.
