摘要

目的

在“双碳”战略与全球能源结构转型背景下，如何实现传统能源系统的高效低碳化运行是当前亟需突破的难题。为此，构建了一种耦合热泵(heat pump，HP)技术的低碳排冷热电联供(combined cooling

heating

and power，CCHP)系统。

方法

通过多级余热回收与温区协同匹配机制，优化能量梯级利用路径；建立涵盖热力学、环境友好性、经济及㶲经济性能的多维度评价模型，并与传统系统性能进行了对比。

结果

经济性分析结果显示，HP的引入使单位产电成本从1.24元/(kW⋅h)增至1.43元/(kW⋅h)，但单位产能成本从0.24元/(kW⋅h)降至0.22元/(kW⋅h)，综合能效提升；灵敏度分析结果显示，运行时间与利率对成本影响最大；㶲经济分析表明，透平、碳捕集与封存(carbon capture and storage，CCS)系统和压缩机分别贡献67.019%、17.107%和8.169%的㶲损失，是未来优化的核心方向。

结论

研究成果为低碳排CCHP系统的设计与推广提供了理论支撑。

Abstract

Objectives

Under the background of the “dual-carbon” strategy and the global energy structure transition

achieving high-efficiency and low-carbon operation of conventional energy systems is a pressing challenge that needs to be overcome. To address this

an low-carbon-emission combined cooling

heating

and power (CCHP) system coupled with heat pump (HP) technology is proposed.

Methods

A multi-stage waste heat recovery and temperature-zone coordinated matching mechanism is employed to optimize the energy cascade utilization pathway. A multi-dimensional evaluation model

covering thermodynamics

environmental friendliness

economic efficiency

and exergoeconomic performance

is established and compared with the performance of conventional systems.

Results

The results of economic analysis show that the heat-pump integration increases the unit power generation cost from 1.24 to 1.43 yuan/(kW⋅h)

but reduces the unit capacity cost from 0.24 to 0.22 yuan/(kW⋅h)

resulting in an overall improvement in energy efficiency. The sensitivity analysis results reveal that operating duration and interest rate have the greatest impact on costs. Exergoeconomic analysis indicates that the turbine

carbon capture and storage (CCS) system

and compressor contribute 67.019%

17.107%

and 8.169% of the exergy loss

respectively

representing the core directions for future optimization.

Conclusions

These research findings provide a theoretical basis for the design and promotion of low-carbon-emission CCHP systems.
