太阳能冷热电联供作为一种由多个子系统集成的复杂系统,目前仍存在系统运行不稳定、子系统之间相互耦合匹配复杂、评价指标多元化等问题.在国内外太阳能冷热电联供文献研究的基础上,从系统类型、采用工质的特点及适用范围、系统运行模式与策略、系统评价指标等角度分析了现有太阳能冷热电联供研究的现状与进展.提出太阳能冷热电联供各子系统的工质应根据应用特点进行针对性选择;冷热电联供的运行模式应根据用户具体需求及系统最佳运行策略而定, 且系统最佳运行策略受系统运行工况及优化目标的影响较大;系统的评价应针对联供系统的热力学性能、经济性能和环境友好性能三个方面得出一套统一的综合评价指标.

As a complex system integrated by multiple subsystems, the combined cooling heating and power (CCHP) system driven by solar energy has disadvantages of unstable system operation, coupling between subsystems, evaluation diversification. The status and the progress of CCHP systems were analyzed from the aspects of types, characteristics and scopes of working fluids, operation modes and strategies, evaluation cri-terion of the systems. We proposed that the working fluid in each subsystem should be chosen according to the specific application characteristics;the operating mode of the CCHP systems should be determined on the basis of the specific requirements of users and the optimal operation strategy which mainly depends on the working conditions and the optimal objects; a unified and comprehensive evaluation criterion of the CCHP systems should be given after evaluating the thermal properties and the performance of economic and environ-mental friendliness.
