The low pressure side is the larger of the 2 pipes coming out of or going into the outside compressor unit. The high pressure side is the small diameter line. 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.

The mass flow rate and operating pressures of Freon™ MO99 are the closest of all the mineral oil compatible replacement products and will likely perform adequately in an existing R-22 system with a capillary tube expansion device. However, for optimal results, it is recommended to replace the capillary tube with a TXV when possible. R22 has a very similar boiling point to R290 (-41.4°F to 44°F; that’s only a 2.6°F difference). At 100°F, however, the pressure of R22 is 195.9 psig and the pressure of R290 has a pressure of 174.3 psig (check the R290 PT chart below). This is a 20+ psig difference and you will easily tell if you have an R290 or R22 freon. mitsubishi mr slim R22 proper pressures @94 degrees.

This refrigerant is also suitable for use in many medium-temperature refrigeration systems that formerly used R-22. Freon™ 407C is the registered trademark for a blend of HFC-32/HFC-125/HFC-134a with a correspondingAt 318.5 PSI, the saturated temperature is 100°F. If you measure 118 PSI on the low-pressure side of the system, then you know that the saturated temperature of the refrigerant flowing through the middle of the evaporator coil is at 40°F. This is a useful number when combined with the temperature of the tubing near the pressure port.Temperature and pressure chart for refrigerants R22, R410A, R12, R134A, R401A, R409A, R502, R404A, R507A, R408A and R402A. Engineering ToolBox - Resources, Tools and Basic Information for Engineering and Design of Technical Applications! The low pressure side is the larger of the 2 pipes coming out of or going into the outside compressor unit. The high pressure side is the small diameter line. 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. 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.R134a has a lower thermal conductivity than R22, so an R134a system needs a larger heat exchanger. A system circulating R134a needs a dryer, because of the propensity of the refrigerant to absorb water. R134a swells the rubber components in the refrigeration system and causes leaks. R134a corrodes copper, so the system must include an additive ...Well water pressure tanks are connected to water wells and perform several vital functions in water supply systems.

To make a short story long, R410A and R22 are refrigerants. They are both good refrigerants and they both work, but they have to be charged in the system at different pressures. R410A is a higher pressure system and R22 is a lower pressure system. The suction pressure of AC for R22 refrigerant is about 60 TO 70 PSI and the discharge pressure is 250 TO 300.
