Energy Transfer in a Heat Pump System
The total amount of energy transfer by work into the heat pump over the 14-day period is 0.0496 GJ. The amount of energy that the heat pump receives by heat transfer from the well water over the 14-day period is also 0.0496 GJ. The heat pump's coefficient of performance is 8.51 x 10^-6.
Understanding Energy Transfer in a Heat Pump System
In a heat pump cycle operating at steady state, energy is transferred by heat from well water at 10oC and to a building at a certain rate. Over a 14-day period, the heat pump receives electricity and performs various energy transfers.
Calculating Total Energy Transfer by Work
The total energy transfer by work into the heat pump can be calculated using the principle of energy conservation. Given the data, the total energy transfer by work into the heat pump over the 14-day period is 0.0496 GJ.
Determining Energy Transfer from Well Water
The energy transfer by heat from the well water can also be calculated using the energy conservation equation. The amount of energy that the heat pump receives by heat transfer from the well water over the 14-day period is 0.0496 GJ.
Understanding Coefficient of Performance
The coefficient of performance (COP) for a heat pump is a crucial parameter in determining its efficiency. In this case, the heat pump's coefficient of performance is calculated to be 8.51 x 10^-6, indicating the effectiveness of the heat pump in transferring energy.
By understanding these calculations and principles, we can evaluate the energy efficiency and performance of a heat pump system over a specific period.
