Most TEV (TXV) are set to deliver about 6 degs of superheat. Now subcooling is the temp of the liquid coming from the condenser towards the TEV. the closer to the TEV the greater the cooling. If you measured the temp at the outlet. of the condenser it could be between 1 or 2 degs to 4 or 5 degs below the saturation.12.7 psi. - 20°F. - 28.9°C. 16 psi. What should the high and low side pressures be for 404A? It is necessary to have the temp at 34. When the system is running, the temp in the evap is usually 24 so 32 suction pressure. The liquid line pressure needs to be higher than the outdoor ambient's saturation temp, so it would be at least 257.Optimal walk-in cooler pressures are crucial for maintaining the desired temperature and ensuring the longevity of stored products. While the exact pressures can depend on various factors, generally, for R404a refrigerant, suction pressure should be approximately 60-70 psi and discharge pressure around 225-250 psi.It is now less than a year until R404A is banned in new commercial refrigeration applications in Europe, and from 2020 onwards, only recycled refrigerants can be used for servicing.
