R22 low side pressure at 70 degrees

The main reasons your compressor will have simultaneously low head pressure and high suction pressure is due to: Bad or leaky compressor valves. Worn compressor piston rings. Leaky oil separator return line. Your compressor valves may become inefficient due to poor sealing from dirt and debris deposits.

It is important to know the range of these pressures in order to understand why and how charging and recovery are performed. One of the first refrigerants to go was our friend R-12. At this point in time, in the early 1990’s, R-12 had seen the majority of it’s usage in automobile air conditioning. R-12 was banned in new automobiles and was replaced with by the HFC refrigerant we all know today as R-134a. Now, there are still some R-12 applications out there today.

What is the suction pressure of an R22 unit operating at an ...You need at least a 50 degree IWB and 55 degree ODB at minimum to measure superheat accurately. You can block the coil to simulate your ODB target if it's too low, but be careful how much you raise the head pressure or your SH will drop to 0 degrees. Use a superheat charging chart to determine whether or not you can check the charge.Experts typically recommend a range of 10 to 15 degrees Fahrenheit. If your system’s subcooling level falls within this range, you’re in good shape! If not, you may need to make some adjustments to improve efficiency and performance. Troubleshooting Subcooling Issues Common Causes of Low Subcooling. Low subcooling can be a bit of a headache.Originally Posted by Andhen. 30 because 30 degrees subcooling. A saturated head pressure 30°F above outdoor temp, doesn't get you 30°F of subcool. While 8 and 10 SEER A/Cs did often have to run 30° saturation over outdoor temp, you still only had 8 to 12° of subcool. Charge by subcool, or by superheat.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. This script determines the gas pressure based on temperature of R22 refrigerant. R22 or HCFC-22 is a single component HCFC refrigerant with low ozone depletion potential. It has long been used in a variety of air conditioning and refrigeration applications in a variety of markets, including appliance, construction, food processing, and ... Not much more to add, really. 0 PSI on R-12 is about -21 degrees. Depending on your target temperature, you will be very close to, if not below atmospheric on the low side. If you had to put more than half the charge in it, you probably have an obstruction at the metering device.
