Using an R407c pressure temperature chart you can also check what temperature a saturated R407c liquid and vapor should have at -10.4 psig to 437.5 psig pressure.. …An R410a and R22 charging calculator or the "Non TXV Charging Guide" are required to determine the target total superheat. Because these systems do not "control superheat" it is critical that the airflow be as close to possible to correct prior to charging as the system will be charged to the airflow. Figure 1 is an example of a superheat-charging curve instead of a table. The curve is based on 400-cfm/ton airflow at 50% relative humidity across the evaporator coil. The steps to charge a system according to this curve are listed below. 1. Measure indoor drybulb temperature (DBT).Excessive or high superheat is an indication of insufficient refrigerant in the evaporator coil for the heat load present. This could mean that not enough refrigerant is entering the coil or this could also indicate an excessive amount of heat load on the evaporator coil.The main points to be covered are: How refrigerant exists in a system, Basic principles of P-T charts, Saturated refrigerant, calculating Superheat and calculating Subcooling.

In the case of a …It's been some time since we last published a new article on these important HVAC system measurements. David Richardson provides a fresh review of the procedures. Now refer to the “TXV System Charge Level Chart “A” or “B” pages 3 or 4 (see note below) and find the point where high side pressure and liquid line temperature intersect on the chart. If they intersect in the “Normal” band, the system is close to correct system charge. If they intersect above the “Normal” Before you finish up, let the system run for at least 20 minutes to balance it out. In conclusion, the key to servicing systems that use TXVs is to check the superheat. Many technicians have gotten away from that because systems can be charged using subcooling. Subcooling may be fine for charging, but it’s not a diagnostic tool like superheat.The main points to be covered are: How refrigerant exists in a system, Basic principles of P-T charts, Saturated refrigerant, calculating Superheat and calculating Subcooling. To understand how to calculate Superheat or Subcooling, an understanding of refrigerant phase change in the system and the pressure-temperature relationship is necessary.A solid understanding of superheat and subcooling is essential.
