What is the low side and high side pressure for r410a?
Technicians with R-22 experience will need to become familiar with working with high and low side pressures that are much higher when using R-410A. A typical R-22 system operating normally with a head pressure of 260 psig at a 120-degree condensing temperature and a low side pressure of 76 psig at a 45-degree evaporator saturation temperature will find the equivalent pressures in a R-410A system to be much higher.A normally operating R-410A system with the same condensing temperature of 120 degrees and a 45 degree evaporator saturation temperature will have a high side pressure of 418 psig and a low side pressure of 130 psig.Although refrigerant 410A is a near-azeotrope and has a slight temperature glide, there is no need to correct for refrigerant dew point and bubble point differences. Superheat and sub cooling calculations can be calculated the same way we have always done with R-22 refrigerant. The only difference will be the higher pressure-temperature relationship when reading the temperature-pressure chart. The temperature glide for R-410A is only .3 degrees Fahrenheit and can be ignored and fractionation is not a concern.
What is the low side pressure on a home air conditioner?
60 psi for r-22. 125 for a 410a
If the evaporator outlet temperature on a r-410a system is 50p and the evaporator superheat is 10p, what is the evaporating pressure of the refrigerant in this system?
8.2
Can you recover r-410a freon?
If you add 410A to a heat pump does it put out more heat or less?
Why are there more safety precautions with r410a than with other popular refrigerants like r22 and r404a?
The pressure of R-410A is significantly higher than other refrigerants R-22 and R-404A. This does not mean that R-410A, or equipment containing R-410A is unsafe. It does mean that technicians must use AC equipment; cylinders and service tools have been re-engineered to handle these higher pressures.
What replaced Freon?
R-410a
How do i Read ac manifold gauges?
Look at the pointer on each gauge and the number it is pointing to is the pressure in psig. Under the pointer and below the pressure scale on the face of the gauge are 3 or 4 different colored temperature scales. Each color refers to a particular refrigerant. Determine which refrigerant you are using and the number in that scale is the corresponding saturation temperature at the pressure you are operating at. For example R-22 (light Green scale) at 70 psig = 40*F saturation temp.
Do you have to braze 410a?
Yes, its a requirement of all manufacturers, that i know of, to braze 410a connections with a brazing alloy containing a minimum of 15%
How do you convert a pneumatic test pressure to a hydro test pressure?
Design pressure multiply by 1.1 equal pneumatic test pressure. Design pressure multiply by 1.5 equal Hydrotest Pressure Note: Design Pressure is different from Operating pressure. Design Pressure is equal to Maximum Operating Pressure From: galdo.gaspar@ymail.com
