RS-44 is a non flammable blend of HFC 125, HFC 134a, n-butane, isobutane and isopentane which has a zero ODP and is also compatible with both traditional and synthetic lubricants so that a retrofit is not required. RS-44 is a “Drop-in” replacement for R22 providing an easy and at the same time a long term solution.flow by maintaining a nearly constant superheat at the evaporator outlet. As superheat at the evaporator outlet rises due to increased heat load on the evaporator, the TEV increases refrigerant flow until superheat returns to the valve’s setting. Conversely, the TEV will decrease refrigerant flow when superheat lowers as a result of aTarget Superheat To determine the Target Superheat for an air conditioning system with a fixed orifice (such as a piston or capillary tube) measure the indoor WB (wet bulb) temperature with a digital psychrometer and the outdoor DB (dry bulb) temperature with a standard digital temperature reader.Similar to other HFC refrigerants, like R-407C or R-404A, the lower amount of superheat included in the evaporator capacity results in a slightly lower relative ...Figure 1 is an example of a superheat-charging curve instead of a table.

This formula typically involves measuring the temperature at the evaporator outlet and comparing it to the corresponding saturation temperature at the evaporator pressure.achieving the proper superheat and subcooling settings after converting R22 residential A/C systems with fixed orifice to R422D. If the technician is experiencing high superheat and low suction pressure with the system charged to 96% of the original charge the orifice may be undersized.The water temperature of 212°F (100°C) is the sensible heat. The heat that causes a change of state (water to vapor) with no change in temperature is called latent heat. Latent heat does not affect the temperature. The sum of the sensible and latent heat of the air is called enthalpy or total heat. 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.

A discussion of the relationship between valve capacities and superheat set-tings can be found in Bulletin 10-9. The ratings for evaporator temperatures 40°F, 20°F, -10°F, -40°F in the capacity tables are in accordance with ANSI/ARIOctober 10, 2000. Different types of metering devices have different ways of charging. An air conditioning unit with a thermostatic expansion valve (TXV) is charged to the subcooling of the liquid line leaving the condenser because the superheat is fixed. The superheat is fixed at 8°F to 12°F in most residential air conditioning systems.Take the wet bulb temperature at the closest return vent. Take the dry bulb temperature at the outside intake (out of the sun) Use chart to find target superheat. Add small amount of refrigerant, wait for system to stabilize. Repeat until actual and target superheat values converge. 1. All these would be considered within an acceptable range. Coupled with the knowledge that thermostatic charges for R22 are the proper choice for these refrigerants as well, there is a high likelihood that existing R22 TEV’s and distributors will provide good superheat control when retrofitted to R407A, R407F, R448A, or R449A.Limitations of the Superheat Test First, superheat won’t be accurate unless air˜ow is around 400 cfm per ton, so air˜ow should be mea-sured and improved, if inadequate.
