Normally suction line pressure on air conditioning equipment is about. 45 degF with a suction pressure of 42 psi for Freon 12; 45 degF and about 76 psi for Freon 22; These low side suction line temperature and pressure measurements will vary as a function of refrigerant, ambient temperature and other factors.What are normal operating pressures for 410A mini split? The low side pressure of a typical R410A mini split is between 110-140 psi depending on the operating conditions. However, it should not fall below 100 psi or raise beyond 160 psi. The working pressure of mini splits is depending on factors such as the weather and cooling load.Maybe my instructor said that to check the charge level on a heat pump in heat mode, the subcooling must be between 08-12 degrees F, and the delta T must be 16-20. I had 41 degrees Fahrenheit of subcooling. If the subcooling must be between 08-12 degrees F in heat mode, then my unit was overcharged. But the last time I checked my charge level ...A normally operating R-410A system with the same condensing temperature of 120 degrees and a 45 degree evaporator saturation temperature will have a high side pressure of 418 psig and a low side pressure of 130 psig.

Standard ...Question: A cascade system with one refrigeration cycle operating with R-410a has an evaporator at -40C and a high pressure of 1500 kPa. The high temperature cycle uses R-134a with an evaporator at OC and a high pressure of 1500 kPa. Find the ratio of the two cycles mass flow rates and the overall COP. Answer it carefully, as specific as you can.Using the temperature rise method (CFM = KW (Volts X Amps) X 3.413 divided by (Temp rise X 1.08)), check the airflow. Using the manufacturer's coil specification sheets, confirm the pressure drop across coils. The airflow measurement is used to find the evaporator load, so it must be accurate. Check the system operating pressures.High operating pressures. CO 2 system operating pressures are significantly higher than traditional HFC systems (i.e., those using R-404A or R-410A). ... Although -69.8 °F is well below normal operating ranges, its corresponding saturation pressure is not 60.4 psi.Given my experience with portable dehumidifiers which use R-410A, they are simply not as reliable as those using R-22. Why, it appears that due to the much higher operating pressures with R-410A, the sealed system develops leaks, sometimes with portable dehumidifiers "right out of the box."The best answer is—as usual—whatever the manufacturer says it should be. If you really NEED a general answer, you can generally expect: High Temp or A/C systems to run 6-14°F of superheat. Medium Temp - 5-10°F. Low Temp - 4-10°F. Some ice machines and other specialty refrigeration may be as low as 3°F of superheat.A. the furnace will be designed to operate at the same time as the heat pump. B. the heat pump will operate only in the defrost mode to remove ice from the coil. C. the heat pump will cycle off when the furnace starts to operate. D. the furnace will only operate when the system is set to the emergency heat mode. A.The refrigerant R-134A can boil at 0 °Celsius when the pressure is less than 30 psig.
