High refrigerant pressure
WebFor these blends, the vapor and liquid pressures are only separated by 1 or 2 psi. Because the difference is quite small between the two values some manufacturers’ PT charts will only list one column for these blends. … WebOil trapping in the system. Probably in the evaporator. Excessively low suction pressure. Excessive liquid refrigerant returning to the compressor (flood back). Defective oil pump or the oil pump inlet screen is restricted. Crankcase heater not installed or defective (migration). System is low on refrigerant.

WebWhat causes high head pressure in refrigeration? Once the air gets to the condenser, it will remain at its top and not condense. The subcooled liquid seal at the condenser's bottom will prevent the air from passing out of the condenser. This air and water vapor will take up valuable condenser surface area and cause high-head pressures. WebR404A and R410A are two refrigerants that are commonly used in AC units. The differences between these two refrigerants come down to the pressure level, their chemical composition, and their efficiency. R404A is a hydrocarbon refrigerant that has a high pressure level of 1,500 psi.

WebJan 11, 2016 · Remember, the condensing pressure is the pressure at which the refrigerant is changing phase from a vapor to a liquid in the condenser. There is a pressure-temperature relationship with the condensing pressure because of the phase change. A gauge reading on the high side of the system is all that is needed to find the condensing pressure.
