Energy Efficiency Analysis of Building System Based on Air-Source Heat Pump Considering Comfortability

Building is one of the main parts of energy consumption. To evaluate the energy efficiency of the increasingly popularizing electric power alteration system for buildings, as well as analyze the influence of building set temperature on energy efficiency, we proposed a model of energy efficiency analysis for building energy supply system based on air-source heat pump, and introduced its computation method. First, a model of electric heating system for buildings based on air-source heat pump is proposed. Next, the energy efficiency index for building electric power alteration system is defined. Finally, typical cases are built to study the impact of the setting-point indoor temperature on the energy efficiency of the system.
