Abstract Although significant progress has been made in relation to air source heat pump (ASHP) modeling, it is difficult to reflect the actual dynamic characteristics of the start-up process by a completely theoretical model, and a regression model cannot reflect the energy efficiency differences between systems intuitively. A semi-theoretical model for fixed speed ASHP which considers the modifications of no-load power consumption, cycling losses and defrost discount has been developed based on the statistical analysis of field monitoring data. Thermodynamic perfectibility was introduced to evaluate the steady-state performance at continuous operation. By taking the running and cycle time as input parameters, it is possible to relate the operation mode to system energy efficiency. In the verification of the seasonal coefficient of performance, the error is

空气源热泵系统能效评估的半理论模型

摘要 空气源热泵（ASHP）建模虽然取得了重大进展，但完全理论模型难以反映启动过程的实际动态特性，回归模型也不能反映能效差异。直观地在系统之间。在对现场监测数据进行统计分析的基础上，建立了考虑空载功耗、循环损耗和除霜折扣修正的定速ASHP半理论模型。引入热力学完善性来评估连续运行时的稳态性能。通过将运行时间和循环时间作为输入参数，可以将运行模式与系统能效联系起来。在验证季节性绩效系数时，
