Evaluation of thermal performance of air source heat pump heating system based on electricity equivalent

Thermal performance assessment and optimization for energy conversion utilization systems are of high significance in building efficiency. Generally speaking, the evaluation actual thermodynamic system is mainly based on First law thermodynamics, with emphasis quantity consumption, while ignoring quality. Thus, it results a one-sided analysis saving. In this paper, electricity equivalent used to analyse evaluate air source heat pump heating under different working conditions. Moreover, dynamic thermal performances three typical space devices (radiator, fan coil, radiant floor) investigated compared by weighing both The show that COP radiator, floor 3.00, 3.82, 4.76, coefficient quality 48.32%, 51.43%, 50.57%, respectively. However, robustness its lower than radiator coil. This work can provide reference guidance practical design systems.
