The use of integrated central heating and/or cooling plants to provide heating and/or cooling services for communities or regions is referred to as district energy (DE). Cogeneration is the simultaneous production of electricity and product heat. A trigeneration system also generates cooling capacity. Systems for trigeneration can be beneficially combined with district energy systems. The benefits are especially notable when such combined systems incorporate absorption chillers, as such chilling devices are predominantly heat driven and thus provide an additional use for cogenerated heat. Although some separate applications of DE and trigeneration systems exist or are planned, there are few integrated systems that combine the technologies. One reason is that the optimization and improvement of trigeneration-based DE systems is complex, and requires that system components be integrated appropriately. However, methods for improving existing designs and achieving optimal configurations are in general still not widely available. The proposed research aims to improve existing and planned designs for integrated trigeneration-based DE systems in hopes of achieving optimal systems and configurations. The following principal factors will be accounted for: efficiency, economics and environmental impact. It is anticipated that the proposed research will result in numerous benefits, including improved and optimal designs and configurations for trigeneration-based DE systems, where efficiency, economic and environmental factors have been appropriately accounted for; increased applications of such systems; the provision to society of heating, cooling and electrical services with increased efficiency, economic viability, reliability and safety, and with decreased environmental impact and degradation; and expanded economic growth and employment in this sector of Canada's economy.

使用集成的中央供暖和/或制冷设备为社区或地区提供供暖和/或制冷服务，称为区域能源(DE)。热电联产是电力和产品热能的同时生产。热电联产系统还可以产生冷却能力。热电联产系统可以与区域能源系统相结合。当这种组合系统结合了吸收制冷机时，好处尤其明显，因为这种制冷设备主要是由热驱动的，因此为热电联产提供了额外的用途。尽管DE和热电联产系统的一些单独应用已经存在或正在计划中，但很少有集成系统将这些技术结合在一起。一个原因是，基于三电联产的DE系统的优化和改进是复杂的，需要适当地集成系统组件。然而，改进现有设计和实现最佳配置的方法总体上仍然没有广泛可用的方法。这项拟议的研究旨在改进现有的和计划中的基于三联产的DE系统的设计，希望实现最优的系统和配置。将考虑以下主要因素：效率、经济和环境影响。预计拟议的研究将产生许多好处，包括改进和优化基于热电联产的DE系统的设计和配置，其中适当考虑了效率、经济和环境因素；增加这种系统的应用；向社会提供效率更高、经济可行、可靠性和安全性更高的供暖、制冷和电力服务，并减少对环境的影响和退化；以及扩大加拿大经济这一部门的经济增长和就业。
