Heat pump supply and return temperatures - Physics Forums
WEBJul 9, 2013 · Heat pump supply and return temperatures are important because they can indicate the efficiency of the heat pump system. A larger temperature difference between the supply and return temperatures can indicate that the heat pump is working harder to maintain the desired temperature, which can result in higher energy consumption and costs.
Energy problem dealing with heat extracted from cold air - Physics …
WEBNov 1, 2013 · Now, to find the amount of energy extracted from the cold air outside each second, we can use the equation Qc = Qh - W, where Qc is the energy extracted from the cold air, Qh is the heat delivered to the house, and W is the electrical power used by the heat pump. Plugging in the values given, we get Qc = 2410 J/s - 385 W = 2025 J/s.
Can fan RPM affect power consumption in heat exchangers?
WEBDec 23, 2014 · Fan RPM (revolutions per minute) is directly related to power consumption. As the RPM increases, the fan requires more energy to rotate at a faster speed, resulting in higher power consumption. This is because the fan motor needs to work harder to produce the necessary torque to spin the blades at a higher speed. 2.
