本研究提出了一种有效的热力学转变分析方法。根据火用消耗总是与传热过程耦合的现象，定义了有效热力学温度，然后将实际动力循环或制冷/热泵循环转化为等效的可逆卡诺或逆卡诺循环进行热力学分析。推导的等效逆卡诺循环热储层有效热力学温度是该方法的基础。采用TR-h和TR-q组合图对系统性能和火用消耗进行分析，利用热/功交换和焓变的直观表达，便于性能系数和火用消耗的计算。以R22制冷剂的热泵热水器为例，系统介绍了该方法，并给出了有效热力温度的拟合公式进行论证。结果表明，该方法在变工况下的性能仿真与评估中具有优势，具有良好的应用前景。
An effective thermodynamic transformation analysis method was proposed in this study. According to the phenomenon of exergy consumption always coupling with heat transfer process, the effective thermodynamic temperatures were defined, then the actual power cycle or refrigeration/heat pump cycle was transformed into the equivalent reversible Carnot or reverse Carnot cycles for thermodynamic analysis. The derived effective thermodynamic temperature of the hot reservoir of the equivalent reverse Carnot cycle is the basis of the proposed method. The combined diagram of TR-h and TR-q was adopted for the analysis of the system performance and the exergy consumption, which takes advantage of the visual expression of the heat/work exchange and the enthalpy change, and is convenient for the calculation of the coefficient of performance and exergy consumptions. Take a heat pump water heater with refrigerant of R22 for example, the proposed method was systematically introduced, and the fitting formulas of the effective thermodynamic temperatures were given as demonstration. The results show that the proposed method has advantage and well application foreground in the performance simulation and estimation under the variable working conditions.
