Table 2 Freon™ 22 Superheated Vapor — Constant Pressure Tables V = Volume in m3/kg H = Enthalpy in kJ/kg S = Entropy in kJ/kg·K Saturation Properties in ( ) Freon™ 22 Refrigerant 6These charts are an example of a generic superheat charts for a typical fixed orifice, split res-idential system. These charts should not be used for charging. A typical manufacturer’s recommend-ed subcooling is 12°F (7°C). These are only exam-ples of what the manufacturer’s may recommend. Heed all manufacturer’s indications, instructions R410A unit by lining up the pressure with the appropriate refrigerant scale. In this example the Sat temp is 43 degrees. Subtract the two and you have 10 degrees of Superheat. SUBCOOL The Saturation temperature for Subcooling is acquired from the high side gauge. In this example the Sat Temp is about 110 degrees. Next is to “Minus Liquid Line ...
The pressure-temperature (PT) chart is a valuable tool that service technicians use to check proper system operation. PT charts are most often used for three purposes: to set a coil pressure so that the refrigerant produces the desired temperature; to check the amount of superheat above the saturated vapor condition at the outlet of the evaporator and to …Jul 27, 2020 · When charging a fixed orifice A/C system, you can use the chart below to figure out the proper superheat to set once all other parameters have been accounted for. Alternatively, you can use our special superheat and delta T calculator HERE (top left). If it is using a piston or other fixed metering device, you must refer to the manufacturer's superheat requirements or a superheat chart like the one below. If it is a TXV-type metering device, the TXV will generally attempt to maintain between a 5–15° superheat on the suction line exiting the evaporator coil (10° +/- 5°).evaporator outlet superheat of about 5.6°C (1 0.0°F) at the "A" test condition. For "B", "C" and Maximum Operating test conditions the expansion valve was set 1n a manual operating mode at same orifice setting that was used for the "A" test condition.

•The SUPERHEAT from inside the evaporator to the inlet of the compressor is the suction line temperature at the compressor minus the saturated evaporator temperature (from PT chart). •Amount is determined by indoor wet-bulb and indoor & outdoor dry-bulb temperatures. •Can be as low as 5⁰F & as high as 40⁰F depending on ambient conditions.To use the chart, you will usually need: Outdoor dry-bulb temperature taken in the shade. Indoor return dry-bulb and wet-bulb temperatures. You will plug these into the chart or calculator, and you will get a target superheat, generally somewhere between 5 and 25 degrees. ( HERE is a video showing how to find target superheat.)What is a good superheat and subcooling on 410a? The superheat of your heating and cooling system should be 10F at the evaporator. If a thermostatic expansion valve is present (TXV), the subcooling target range should be between 10F and 18F. Your compressor's temperature should sit between 20-25 degrees Fahrenheit.
As we will see in the R-22 and R-410A examples at the end, target superheat for a system using R-22 and the target superheat for a system using R-410A (or any other refrigerant) are the same. Only the DB and WB temperatures determine the target superheat. Here is the formula we use to calculate superheat: Target Superheat = (3 × TWet Bulb ... Mar 19, 2019 · R-410A, or Puron, is one of the most popular refrigerants in today’s modern world. However, if you rewind just fifteen or twenty years you would find that very little people even knew about it. Most contractors and technicians worked with R-22 systems for home and commercial air conditioning. R-22 had been the standard bearer refrigerant for ... R410a Superheat charts (Cooling, NON-TXV) Instructions Measure wet bulb temperature with a sling psychrometer or a temperature and humidity thermistor. Use a digital thermometer for all temperature measurements. Do NOT use mercury or dial type thermometers.
