This can be contrasted with the CO 2 PH diagram, with a critical point of 88°F. Visit our privacy Installation diagram . Sub Refrig. Refrigerant Piping Requirements notes The second requirement of the refrigerant piping design is to ensure that only liquid refrigerant enters the expansion device. The red dots inside the piping represent discharge vapor. Check with the design engineer for this requirement on your project. It’s possible that no increase in size will be required, but if it is required, and you don’t make the change, you will reduce the capacity of the indoor unit. You might have noticed that we have mention multiple times the need to recalculate if there are any changes, that’s due to the importance of this in VRF System Design and installation. Proper Refrigeration Piping Installation Practices – Installing a new air conditioning and heating system requires skill and knowledge of proper procedures in electrical wiring, controls wiring, and pipework. The pipe sizes are affected by capacity, pipe lengths and the quantity of fittings. data. Using full port refrigerant ball valves with Schrader ports allows for isolation of any indoor unit without having to shut down and drain the complete refrigerant from the system.
