为满足用户夏季制冷冬季供热的多目标需求,本文提出了一种适用于中低温余热的新型冷电/热电联产系统。考虑经济收益,定义了系统在冷电联产和热电联产两种工作模式下的循环总效率,并以之为目标函数,采用蚁群优化算法,针对系统的关键运行参数,分别进行了自编程优化计算。结果表明:新系统在冷电联产和热电联产时,最优摩尔浓度分别为0.525和0.500,循环总效率分别为19.9%和20.0%;在相同余热工况下,与传统系统或已有联产系统相比,新系统循环总效率更高,是一种适用于低品位热源的多目标能源供应形式。
In order to meet the multi-objective requirements of summer heating in summer, this paper presents a new type of cold / heat cogeneration system suitable for low and medium temperature waste heat. Considering the economic benefits, the total cycle efficiency of the system under two working modes of combined heat and power (CHP) and cogeneration is defined. Taking the objective function as the objective function and the ant colony optimization algorithm, the key operational parameters of the system are respectively calculated from Programming optimization calculation. The results show that the optimal molar concentration of the new system is 0.525 and 0.500, respectively, and the total cycle efficiency is 19.9% and 20.0%, respectively. Under the same condition of residual heat, compared with the traditional system or the existing Compared to co-generation systems, the new system has a higher total cycle efficiency and is a multi-objective energy supply suitable for low-grade heat sources.
