Heat Pump - thermodynamics:
Heat Pump: Heat pump is reversed heat engine that removes heat from a body at low temperature and transfer heat to the body at higher temperature. It receive heat Q2 from atmosphere at the temperature T2 equal to atmospheric temperature.
temperature to higher temperature. It supplies heat Q1 to space to be heated at the temperature T1.
Performance of HP: It is measured by coefficient of performance (COP). This is ratio of amount of heat rejected by the system to mechanical work received by the system.
(COP)HP = Q1/W = Q1/(Q1 - Q2) = T1/ (T1 - T2)
