Running pressures for 410a.

To use a 410a PT chart, you need to measure the temperature and pressure of the refrigerant at different points in the system, such as the evaporator, condenser, compressor, and metering device. Then, you can compare these values with the corresponding values on the 410a PT chart to determine the state and condition of the refrigerant.Freon™ 407A are shown in Table 3. The pressure-enthalpy diagrams for Freon™ 407C are shown in Figures 1 and 2. Additional physical property data may be found in other Chemours publications. Thermodynamic properties booklets are also available for Freon™ 407C and Freon™ 407A in both English and metric units.

5.1.2 Heating Operation. Constant evaporating temperature (Te) control Basic target value: R22 = 115°F (46°C), R407C = 118°F (48°C), R410-A = 115°F (46°C) *Compensation is applied. Constant superheated degree (SH =Ts-Te) control Basic 9°F (5°C) compensation is applied.For example, if the HVAC system contains R-410a refrigerant, use the manifold gauges that you only use on R-410a systems to prevent contamination. Turn the thermostat to cool and set the target temperature at least 10 degrees lower than the indoor temperature. Let the system operate for at least 10 minutes to let pressures equalize.Operating an air conditioner for extended periods of time in low temperatures outdoors lowers the suction pressure to a velocity where the oil will not return to the compressor and will run dry. Also, under low ambient conditions "indoors" does not provide sufficient load to change refrigerant from a liquid to a 100% vapor.Instagram:https://instagram. jesus ortiz paz wikipedia ™ 410A Refrigerant (R-410A) Piping Guide for Freon™ 410A (ENG Units) Technical Information Suction Line Size—Evaporator to Compressor ...
