摘要

本研究使用TRNSYS模拟与原型住宅和商业建筑的能源需求数据来评估一个多建筑能源中心与冷热电联产(CCHP)系统的性能。在这个框架内,传统和热电联产(CHP)能源发电技术在不同的情况下实施,以满足能源枢纽系统的冷却、加热和生活热水需求。使用年度模拟模拟详细的系统全年性能。对能源中心模拟结果的能源产生、环境影响和经济影响进行了分析,并与具有独立供暖、通风和空调(HVAC)系统的相同多建筑系统进行了比较。结果表明,与独立系统相比,联合系统在当地能源安全、减排和降低能源中心热电联产系统的运行成本方面具有潜在的优势。结果还表明,与传统的暖通空调系统相比,在多伦多方案中应用热电联产技术可以降低运营成本。最后,对每个模拟系统的环境影响的评估表明,在安大略省情景中,热电联产系统将增加排放。

Investigation of energy, emission, and cost advantages of energy hubs: A simulation case study for Toronto
This work uses TRNSYS simulations with archetypal residential and commercial building energy demand data to evaluate the performance of a multi-building energy hub with a combined cooling, heating, and power (CCHP) system. Within this framework, conventional and combined heat and power (CHP) energy generation technologies are implemented in different scenarios to meet the cooling, heating, and domestic hot water demands of the energy hub system. Detailed system performances over the year are simulated using an annual simulation. The energy generation, environmental impact, and economic implications of the energy hub simulation results are analyzed and compared against the same multi-building system with independent heating, ventilation, and air conditioning (HVAC) systems. The results indicate that a combined system has potential benefits in local energy security, in emission reduction, and in lowering the operating costs of CHP systems in an energy hub as compared to independent systems. The results also indicate that application of CHP technology in a Toronto scenario results in a decrease in operational costs compared to a conventional HVAC system. Lastly, evaluation of the environmental impact of each simulated system indicates that the CHP system would increase emissions in an Ontario scenario.
