Web7 Sep 2024 · Our heat pump’s lifetime coefficient of performance (based on approximately 30 months) is 2.7 based on a flow rate temperature of 45C. In late August, we dropped our flow rate to 35C to see what would happen. Would it continue to heat our home and would it have a marked improvement on our efficiency and COP? WebActual Flow Rate. Actual flow rate is the actual volume of fluid that passes a given point in a pipe per unit time e.g. m 3 /hr. This can be a useful measurement to have, however since gases are compressible the volume of gas will vary depending on its pressure and temperature. Therefore it is generally more useful to have a flow rate ...
