Like every the essential amenities, air air conditioning have end up being an inseparable component of everyone lifestyle. Be it home, office, school, or meetings, wait conditioners find their usage everywhere. Adequate expertise of the device is for this reason mandatory to store it functioning.

You are watching: R22 pressures on 70 degree day

Refrigerant pressure readings measured in ~ the air air conditioning compressor or the condenser units found on high or low-pressure sides are disturbing. This can point out a trouble with the capability of the compressor to develop normal operating push ranges. The cooling capacity of the waiting conditioning device gets impacted by henceforth.

Before knowing about the high-side compressor pressure and also low-side compressor pressure of the waiting conditioner the is being used, over there are few more requisites to obtain first. One must recognize if the refrigerant R22 is gift used, adhered to by the properties and also alternatives.

How to figure Out the air Conditioner Refrigerant?


If the wait conditioning device was purchased before 2010, then it is an ext likely to have an R22 refrigerant. Additional information ~ above the manufacture have the right to be obtained from the template at the appliance out condenser or ~ above the business manual.

The cold wait coming the end from the air conditioners is as result of a chemical referred to as R22 refrigerant or Freon. The environment Protection company (EPA) recognizes it as HCFC-22 (hydrochlorofluorocarbon).

Properties of an R22 refrigerant:

The boiling suggest is -40.8 ℃ in ~ atmospheric push (sea level).The density is 3.66 g/cm3.Colorless gas.Molar mass is 86.47 g/mol.R22 gauge push is 10.9 bar or 158.2 psi.High side pressure generally varies through equipment and also metering controls.Low push or suction side typically varies by equipment.Low-pressure refrigerant transforms on the carrier HVACR at 50 psi (R22 press at 30 degrees) and also closes at 100 psi (R22 press at 85 degrees).R22 push at 85 degrees shows a vapor push of approximately 170 psi at the sea level.On the low-side R22 push at 85 degrees display screens 60 psi, conversely, on the high-side R22 press at 85 degrees shows 250 psi.

For servicing that the compressors, the right means is to follow the company manual. Service manuals are listed with the charging charts through details top top the targeted suction vacuum press (negative) and also the output press of the compressor motor.

High-Side Output pressure in waiting Compressor Conditioner:

For high-side calculation pressure, making use of R22 pressure at 85 degrees is referred to as for 120 degrees.

In instance of making use of R22 inside, or in ~ the ambient room temperature, include 35 degrees to the incoming wait temperature. An calculation high-side compressor press of about 260 psi is used.

High-side waiting Conditioner Compressor Pressure

The output or high-side waiting conditioner compressor engine pressure entails the return of the refrigerant gas, with the suction line, come the compressor.The project of the compressor engine is to compress the low-pressure refrigerant come a high-pressure one. This gas is then condensed, in the condensing unit, right into a refrigerant liquid prior to being returned to the waiting handler.The compressor, condensing coil, and also fan uncover their utilities in cooling the condensing coil external the refrigerated space. The is immersed in the air in ~ room temperature. Warmth flows from hotter space to a much more relaxed space, and also the same applies here together well.

Low-Side entry or Suction Line push in air Compressor Conditioner:

For low-side calculation pressure, utilizing R22 press at 85 degrees is dubbed for 45 levels of the very same compressor model.

In situation of using R22 inside, or in ~ the ambient room temperature, subtract 45 degrees from the incoming wait temperature. The organization chart shows that the suction line press to be used is about 75 psi.

With a temperature mediate chart, one can acquire the straightforward knowledge that the refrigerant push for any type of refrigerant gas and additionally the really ambient temperature.

Reminder: The pressure test gauges measure up the refrigerant pressure in the revolution or equalized air conditioning or warm pump system. It offers awareness only about the refrigerant pressure and also not the quantity of the refrigerant gas existing in the system.

Service manuals of waiting conditioners describe the low-side and also high-side wait conditioner compressor motor pressure:

Low-Side air Conditioner Compressor Pressure:

One have the right to spot the low-side that an air conditioning mechanism inside an waiting handler. The air handler features to happen air v the area that is to it is in cooled.The low-side waiting conditioner compressor engine pressure requires the suction line (low side pressure throughout compressor operation), which has a comparatively low value, as the surname indicates, much less than 100 psi.The refrigerant gas prefer R22 is returned from the cooling coil, the evaporator, to the compressor in the line. This have the right to be experiment by connecting the suction line to a sealed vacuum test gauge ~ above the exact same line.Once the push of the cooling coil is reduced, the compressor permits the fluid refrigerant to be discharged into the cooling coil to obtain an optimum temperature.

There are numerous options easily accessible to select from the amazon, several of which have been enlisted below:
