The net refrigeration effect, or evaporator cooling, is the difference in specific enthalpy of the evaporator, or, 175.41- 109.3 = 66.11 Btu per pound of refrigerant. Three tons of cooling is 600 Btu/minute. Divide 600 by 66.11 and you get the refrigerant flow of 600 / 66.11 = 9 pounds per minute of refrigerant flow required to meet the capacity. This is determined by a refrigerant slider. To determine the evaporation temperature, set the slide on 'dew'. To determine the condensation temperature, set the slide on 'bubble'. 4. Use a digital thermometer to measure the temperature on the installation. Measure the superheating temperature on the suction pipe.
The pressure-enthalpy chart, as shown in Fig. 2, displays all the pertinent properties for a given refrigerant (in this example R22). The bubble to the left is the portion of the diagram where the refrigerant is in the saturated condition. The blue line on the left of the bubble represents the 100% saturated liquid line,.
Finally, class 3 refrigerants show flame propagation at 60 degrees Celsius and have a high heat of combustion. Refrigerants in class 3 are considered highly flammable, while refrigerants in class 2 are considered less flammable. These classifications are used as guidelines for determining how much refrigerant can be used in a closed space.

Refrigerant plays a key role in a refrigeration system. From CFCs to HFCs, learn about refrigerant types and how they help keep different applications cool. ... R407C has almost similar pressures as R22 and hence provides the most straightforward conversion from Freon. It has an ODP of zero and a GWP of 1774. ... Refrigerant Chart. Refrigerant. An R134a temperature‐pressure chart shows what the refrigerant temperature should be at a specific pressure. This can be helpful in A/C diagnosis. MVAC systems that are low on refrigerant will have: Low pressures in Evaporator (low side) and Condenser (high side).
