How do you calculate refrigerant quantity?

Divide the quantity of refrigerant that the heat pump moves by the time it takes to move it. If it pumps 3.6 kilogrammes of refrigerant in 10 seconds: 3.6 / 10 = 0.36 kilogrammes per second. Divide the answer to step 1 by the answer to step 2: 51.2 / 0.36 = 142.2 kilojoules per kilogram.
