Since compressors are essentially constant volumetric flow machines, drop-in compressor behavior will result in a capacity shortfall of 25. However, drop-in of alternative refrigerants in centrifugal compressors requires a speed adjustment to insure surge-free operation without over-compressor (choke) in order to maintain compressor peak efficiency and turn-down capability (6).

It is equivalent to the heat supplied to the evaporator/boiler part of the refrigeration cycle and may be called the rate of refrigeration or refrigeration capacity. 450) larger volumetric flow rate. If the cold store is exposed to direct sunlight then the heat transfer will be higher so an additional correction will need to be applied to allow for this. Take a voltage reading at the compressors terminals, and check measured amps with the manufacturers amp curve for the pressure readings and voltage taken. Based on historic sliding cardboard charge calculators,. The RefrigerantCharge Calculator takes the different categories as input parameter for calculation and offers a simple and quick method to determine the maximum possible charge quantity, Various classifications, such as location class of the refrigeration system, access area category, application selection, type of refrigerant and room dimensions are considered, The calculation currently includes the following refrigerants: R454C, R454A, R455A, R454B, R452B, R152a, R1234yf and R1234ze.
