Triple Points SubstancesJun 12, 2023 · High Head Pressure, Normal Suction Pressure . High Head Pressure, Normal Suction Pressure is a common problem that can occur in an air conditioning system. It occurs when the compressor’s condensing unit has difficulty turning the refrigerant from gas to liquid because of high outside temperatures or inadequate airflow through the outdoor coil. For instance, R410a at 32⁰F saturation corresponds to a pressure of 101.6 PSI. To protect the system from freezing up, the switch setting will need to be set in and around 101.6 PSI. When speaking in regards to refrigeration, the low pressure switch is usually set up to shut down the system when it reaches set point or after a pump down .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.Need a model number for more information on the ice machine, for proper pressures for the system, but the service manual will tell you. But it sounds like the right answer, 75% of the charge for an ice machine is needed for harvesting, you can be very low on refrigerant and you'll still make ice. HVAC R22, 410A Refrigerants!

High side pressure typically varies by equipment and metering controls. Low pressure or suction side typically varies by equipment. Low-pressure refrigerant turns on the carrier HVACR at 50 psi (R22 pressure at 30 degrees) and closes at 100 psi (R22 pressure at 85 degrees). R-404A History. R-404A rose to prominence in the late 1990’s with the phasing out of CFC and HCFC refrigerants like R-12 and R-502. There had to be a replacement for the Ozone damaging refrigerants of the past and the successor was the HFC R-404A that we all know of today. 404A’s reign however was short lived.What is the normal suction pressure and discharge pressure of or freon R22 compressor. With 90 F outdoor temperature and 79 F indoor temperature you can expect a 120 F condensing temperature, (ambient plus 30). 90 F + 30 F = 120 F ; Convert temperature to pressure, R 22 at 120 F = 260 psi ; Indoor temperature (70 F) minus 40 F …Freon™ 410A is intended for use in new air conditioning applications that have traditionally been serviced by HCFC-22. Many other applications are also possible, such as medium- and low-temperature refrigeration. Due to the significantly higher pressures that Freon™ 410A exhibits compared to HCFC-22, a typical compressor designedThe condenser comes charged with 15 feet of 410A.
