摘要

复叠式高温热泵是一种有效利用低品位可再生能源的技术,为提升复叠式高温热泵在印染行业应用的经济性,基于热力学循环分析构建适用于工业余热回收-再利用的复叠式高温热泵模型,以单位成本热负荷为优化目标,综合考虑热经济成本和循环性能,采用数学分析法开展针对蒸发/冷凝温度组合参数的优化设计研究。结果表明：对于表现最优的工质对R152a/R245fa,在冷凝温度为370.41 K的工况下,蒸发温度的优化可使单位成本热负荷提高约14.5%;在蒸发温度为297.43 K的工况下,冷凝温度的优化可使单位成本热负荷提高约24%,最大单位成本热负荷可达2.84 W/（元·a）。另外,热经济性目标同时受制热系数和比供热率的影响,存在最佳制热系数和比供热率的组合使单位成本热负荷最大。

Abstract

Cascade heat pump is an effective technology for utilizing low-grade renewable energy. In order to improve the economy of the application of cascade heat pump in the printing and dyeing industry, a cascade high-temperature heat pump model suitable for industrial waste heat recovery and reuse was constructed based on the thermodynamic cycle analysis. Taking the heating load per unit total cost as the optimization objective, considering the thermal economic cost and system performance, the optimization design of the combined parameters of evaporation and condensation temperature was carried out through the mathematical analysis. Results show that for the optimal refrigerant combination of R152a/R245fa, the optimization of evaporation temperature can increase the heating load per unit total cost by about 14.5% at the condensation temperature of 370.41 K. Under the condition of evaporation temperature of 297.43 K, the optimization of condensation temperature can increase the heating load per unit total cost by about 24%, and the maximum heating load per unit total cost reaches 2.84 W/（yuan·a）. In addition, the thermoeconomic objective is affected by the heating coefficient and the specific heating rate, and there exists optimal combination of the heating coefficient and the specific heating rate, which maximizes the unit cost heat load.
