Enter the values of heat output, HR(W) and Work input, W(W) to determine the value of Heat Pump Efficiency, E.
Heat Pump Efficiency Formula:
A heat pump is a mechanical device used for heating or cooling by transferring heat between two areas. It works on the principle of moving heat from a cooler space to a warmer one using a refrigeration cycle. Heat pumps can extract heat from the outside air, water, or the ground and use it for heating the inside of a building or transferring it for cooling purposes.
The efficiency of a heat pump is often measured in terms of its Coefficient of Performance (COP) for heating (Ehp), which indicates how effectively it converts electrical energy (input) into heat energy (output).
The key factors affecting the heat pump efficiency include the outdoor temperature, indoor temperature, and the specific technology used in the pump. A higher COP means the heat pump is more efficient, as it delivers more heat output per unit of energy consumed.
The energy efficiency ratio (EER) and the seasonal energy efficiency ratio (SEER) are also used to assess a heat pump’s efficiency over time.
Heat Pump Efficiency, E in percentage divide the heat output, HR(W) in Watts by the Work input, W(W) in Watts and multiply by 100 to convert it to percentage.
Heat Pump Efficiency, E = HR(W) / W(W) * 100
E = heat pump efficiency in percentage.
HR(W) = heat output in Watts, W.
W(W) = work input in Watts, W.
Heat Pump Efficiency Calculation:
1.Given: Heat Output, HR(W) = 4500W, Work Input, W(W) = 1500W.
Heat Pump Efficiency, E = HR(W) / W(W) * 100
E = 4500 / 1500 * 100
E = 300%.
2.Given: Heat Pump Efficiency, E = 350%, Work Input, W(W) = 1800W.
Heat Pump Efficiency, E = HR(W) / W(W) * 100
HR(W) = E * W(W) / 100
HR(W) = 350 * 1800 / 100
HR(W) = 6300W.
