Trying To Figure Out The Pressures A R22 Condenser Should Read At With the equipment off and stabilized, from the r22 refrigerant pressure tables, given in this article, the r22 pressure will be a bit lower, at 132.2 psi. calculated pressure: r 22 high side pressure = (75 x 2) 50 = 200 psig this is "high" so you should take this as an upper limit. r 22 high side typical operating pressure range:. Trying to figure out the pressures a r22 condenser should read at around 75 degrees. contractor's assistant: who makes your ac unit? when did you last replace the air filter? just replaced and american standard. contractor's assistant: what have you tried so far with your american standard unit? checked freon using manifold gauges.
Pt Condenser Chart For R22 Refrigerant Physical properties of r22. in parallel to using the r22 pt chart, professionals will usually need to know some of the following r22 physical properties: r22 liquid density at 69°c: 1.49 g cm 3. r22 gas density at 15°c: 3.66 kg m 3. triple point temperature: 115.76k. critical pressure: 49.36 bar. heat capacity ratio at 86°f: 1.178253. I ended up with a low side pressure of 70 psi and a high side of like almost 270 psi on the high side. the ambient temperature was about 89 degrees and 70% humidity. heat index was like 96 degrees. this greatly increased airflow through the air handler on both sides and gave the owner a supply vent temperature of 60 1 degrees. The gauge reading are always influenced by: 1) outdoor temperature. 2) indoor temperature. 3) refrigerant (usually r 22). 4) airflow across the outdoor coil (about 1000 cfm per ton). 5) airflow across the indoor coil (about 400 cfm per ton). 6) the efficiency of the system (a design issue). We will first examine the low pressure side of the system, otherwise known as the vapor or suction line. during air conditioning mode, the pressure on the vapor line of an r 410a system will be somewhere between 102 to 145 psig. if the system had r 22, the vapor pressure would be between 58 to 85 psig but these pressures will be dependent on.

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. R22 pt chart was used to make the relationship between pressure and temperature. it is used to explain the value of pressure of r22 refrigerant for a certain value of temperature. these values of temperature and pressure are used to diagnose the working of refrigerant and air conditioners. let’s get started with the r22 pressure temperature.
