My suction pressure is pretty low my superheat at compressor is 20 degrees and sub cooling is at 20 as well.Dec 28, 2011 · A high discharge pressure could be substituted for low flow. To determine the proper set-points for these substitute trip set-points, you would need to know the full range of possible suction conditions and the pump curve. If the pressure in the flash drum is constant and stable, then suction pressure at the pump would represent drum pressure ...Jan 28, 2023 · Restriction in the Refrigerant Flow. Another cause of low suction pressure high head pressure can be a restriction in the refrigerant flow. This can be caused by a blockage in the refrigerant lines or a problem with the compressor, and can lead to low suction pressure and high head pressure. 3. Faulty Compressor.The recommended low-pressure control setting is a cut-out pressure of 50 psig. Make sure the pressure control you are using on a 410A system has the correct pressure range, allowing it to be adjusted for the correct pressures. Oil R-410A systems use a synthetic polyolester (POE) oil.A R-410A evaporator running below 100 psig will freeze-up just like its R-22 cousin. One of the most common causes of low suction pressure is loss of critical refrigerant charge caused by small leaks over time.

Evaporating pressure: Low-side pressure, suction pressure, back pressure. Figure 1. A basic refrigeration system showing refrigerant pressures, states, and conditions. (Courtesy of ESCO Press.) Condensing Pressure The condensing pressure is the pressure at which the refrigerant is phase changing from a vapor to a liquid. This phase change is ...Suction Side Problem Areas. The first thing to check the water level of the pool. If your water level is below the skimmer, your pump will suck in air and produce low water pressure. If It sucks in too much air the pump may lose prime all together. To fix this problem, make sure that the water level is at least halfway up the skimmer door. ….

At an external temperature of 95°F, a high-efficiency condensing unit employing R-22 generally operates with a suction pressure of around 68 psi and a discharge pressure of about 250 psi. What should the high and low side pressures be as a result? At 90 degrees Fahrenheit or less, the low-side pressure should be around 30 PSI.Currently working on a Bremar ice maker. Just did a compressor change and thought I weigh charged it perfectly. But it's not making good ice. I have only a suction port to read the pressures, and I'm getting 300kpa at the beginning of the 8.5 min cycle, and around 240kpa by the end. It runs for 8.5miutes then goes on defrost to drop the ice made.
