for Suva® 410A, R = 0.11455 kJ/kg • K One atmosphere = 101.325 kPa Reference point for enthalpy and entropy: hf = 200 kJ/kg at 0°C sf = 1 kJ/kg • K at 0°C Equations 1. Conversion FactorsŠSI Units to IP Units Properties listed in the following thermodynamic tables in SI units can be converted to I/P units using the conversion factors ...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 ...Determining the Proper Subcooling Level for R410a. Getting the right subcooling level for R410a is crucial. Factors like system design, ambient conditions, and equipment type influence subcooling requirements. Typically, R410a systems require a subcooling level of 10-15°F (5-8°C).Indoor HFC-410A —TXV Unit Size Catalog Number 2-Ton Y0498 3-Ton Y0499 4-Ton Y0500 5-Ton Y0501 6-Ton Y0502 COOLING SYSTEM HFC-410A Total equivalent length = 240 feet (Piping and all fittings, etc).

Superheat = Actual Temperature - Dew T emperature Example: Find the superheat on a system which uses Genetron ® R-422D when the pressure at the evaporator outlet reads 60 psig and your surface thermometer reads 45.5°F 60 psig yields ~ 35.5°F (using dew point) Degree of Superheat = 45.5°F - 35.5°F = 10°F SUBCOOLING Procedure: •Step 3. Subtract the evaporator saturation temperature from the thermocouple temperature. This difference is the system superheat. This shows the temperature rise above the bubble point temperature of the system. Review the operating specifications for your system to determine the proper superheat. Inadequate superheat can cause liquid ...If the R410A units low pressure was 110 psi (755 kPa) and the suction pipe temperature was 12ºC then: 110 psi (755 kPa) converted to temperature is 2ºC, so we then subtract 2 from the 12º pipe temperature which results in a superheat of 10ºC; indicating in this case it’s a little high and requires lowering.…

Furthermore, R410A is an HFC and is commonly used in residential and light commercial HVAC equipment for air conditioners and heat pump systems. Additionally, it widely replaces HCFC R-22 which was mandated by the ... I realize there is a calculation for your target superheat (eg. (IWB)*3-80- (OAT)/2=Target Superheat. However most units that I have come accross DO NOT specify the target subcooling (I speak of TXV/13 SEER units of course). I was wondering if anybody here knew of some calculation to determine this. section 8 application louisville ky Use a fixed orifice charging chart like the one pictured below to obtain proper superheat. For Example, if the wet bulb temp reading is 68°F and the outdoor dry bulb temp reading is 90°F then the required superheat will be 14°F, according to the charging chart below. Superheat with a TXV.
