Pressure Control Settings Low Pressure switch setting for an R-12 general-purpose walk-in cooler without pump down (temperature controlled by a pressure switch.) Assume a 40-degree fixture temperature and a 20-degree TD between the fixture and the evaporative temperature. • Box Temperature = 40ºF (Fixture Temperature)This is the number of degrees a vapor is above its saturation temperature (boiling point), at a particular pressure. Calculate Superheat. To determine the superheat of a system: Using a gauge, measure the pressure on the low side (suction) line. Using a chart for the type of refrigerant, convert pressure to temperature [Saturation Temperature].Here is the full R22 pressure chart from the low side (-60°F) all the way to the high side (155°F): Table of Contents. R22 Pressure Temperature Chart. What Are Normal …

The suction pressure of AC for R22 refrigerant is about 60 TO 70 PSI and the discharge pressure is 250 TO 300. What is boiling point of R-22? R22 is a colorless, odorless gas and has a boiling point of about -41.44°F (-40.8°C) .

With low side blue gauge on the suction line service port, we measured 130 psi pressure that correlates (according to R-410A PT chart) to about 45°F. The clamp-on thermometer shows that the saturated refrigerant temperature is 56°F. Here’s how to calculate superheat for this system: Superheat (R-410A) = 56°F – 45°F = 11°FI had R22 central air system which worked adequatly. The evaporator produced temperature in the range 35-40 degrees. The compressor got flooded during Sandy, and was replaced with the new R407C based unit. No changes were made to evaporator. The low side pressure is around 60 psi, the high side pressure is around 180 psi.R22 pressure at 85 degrees shows a vapor pressure of around 170 psi at the sea level. On the low-side R22 pressure at 85 degrees displays 60 psi, whereas on the high-side R22 pressure at 85 degrees shows 250 psi. For servicing of the compressors, the right way is to follow the service manual.R22 Pressure Temperature Chart Printable PDF Temp er atu r e (° F ): Temp er atu r e (° C): R22 P r essu r e (p si g ): ... 70° F 21. 1° C 121. 4 psi g 71° F 21. 7° C 123. 6 psi g 72° F 22. 2° C 125. 7 psi g 73° F 22. 8° C 127. 8 psi g 74° F 23. 3° C 130. 0 psi g

The boiling point of R22 is -40.8 degree Celsius (-41.4 degree F).

I changed filter when I arrived evap coils were clean . Super heat rose to about 10 degrees but sub cooling stayed same . I then dumped some refrigerant and superheat hit 20 degrees and sub cooling dropped to about 22 degrees .

Example: The air entering the condenser coil is 70 degrees dry bulb, and the condensing temperature is 100 degrees, which corresponds to about 198 psig for r22 refrigerant. This is an example of ambient plus 30 for those that are new to this forum. Lastly, I understand all the variables involved.R404A Pressures On A 70-Degree Day? If you check the chart above, you can see that the pressure of the liquid R404A refrigerant is 149.3 psig. If you are measuring the pressure of a 404A gas (vapor), your gauge meter should read 147.4 psig on a 70-degree day. The difference between liquid and vapor pressure here is 1.7 psig.

The maximum recommended temperature is often around 150 to 160 degrees Fahrenheit (65.6 to 71.1°C) for the condenser coil. What is normal subcooling for 410A? Normal subcooling for R-410A systems can range from 10 to 20 degrees Fahrenheit (5.6 to 11.1°C) depending on the specific system design and conditions.

The perfect refrigerant reading depends on several factors, like atmospheric pressure and temperature. I like to see an average range of 58-85 PSI on the low side and 120-300 PSI on the high side. These indicate that the unit is running okay and should be cooling properly. TL;DR: R22 is almost phased out and even banned.

In today's world of varying system efficiencies and ages of equipment, it is more proper to use CTOA when expressing how much hotter the condensing temperature is than the air passing through it. For example, if the condensing temperature is 100°F and the ambient is 80°F, the CTOA would be 20°F (100°F - 80°F).As a ballpark & it depends on a lot of factors, suction should be in the range of 60 to 80 & head should be in the range of 150 to 300. I've got a 2.5 ton heatpump, @ 90 degrees in heat mode the suction should be @ 74 and the head should be @ 255.

That’s with a Fahrenheit of 70–74 degrees Fahrenheit as the ambient temperature. Low and high side pressures should increase as the ambient temperature rises. The high-side pressure on a fully operating system will be around twice the ambient temperature + 50 PSI.The low pressure side carries R22 gas while the high pressure line carries R22 in a liquid state. R22 changes from a liquid to a gas in the evaporator coils of the air handler.
