What should R134A pressures be?

As an air-conditioning refrigerant in newer automobiles, the optimal running pressure for R134A is between 22 and 57 pounds per square inch.

What should the high and low side pressures be for R134A?

R134a Pressure Gauge Chart

Ambient Temperature (°F) Low Side High Side
90° 50-55 psi 250-275 psi
85° 50-55 psi 220-250 psi
80° 45-50 psi 175-220 psi
75° 40-45 psi 150-175 psi

What is the 134a temperature in the evaporator?

R134a Refrigerant. It exists in gas form when expose to the environment as the boiling temperature is -14.9°F or -26.1°C.

How cold should R134a get?

On r134a systems about you want about 15-20 degrees of subcool. if its less than that, the system needs more freon.. if its over that, it has too much freon. For your superheat numbers, around 15 degrees is about the best you’re gonna get.

Will overcharged car AC not cool?

The likely symptoms of an overcharged AC are poor cooling, no air coming out of the wents, weird noises from the engine bay, and check engine light turning on. Because the AC coolant is toxic, fixing an overcharged AC is a job for a professional AC mechanic.

How cold should R134A get?

How much subcooling do I need for R134a?

about 9 K
The increase in subcooling is a result of both reduction of condenser exit temperature and increase of saturation temperature. Fig. 5 shows that the COP undergoes a maximum for both refrigerants at similar values of subcooling, i.e. about 9 K for R134a and around 11 K for R1234yf.

What temp should car air con be?

Tips for operating the air conditioning system The ideal temperature is between 22 and 25 degrees.

What should air temp be coming out of vent?

If the AC system is operating correctly, then the air coming out of your vent should be about twenty degrees cooler than the regular temperature inside. So, if you’re cooling it and the house is 80 degrees, then you would ideally want the air to be about 60 degrees.
