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/或制冷服务被称为区域能源（DE）。热电联产是同时生产电力和产品热量。三联产系统还产生冷却能力。三次联产系统可以有利地与区域能源系统相结合。当此类组合系统包含吸收式制冷机时，其优势尤其显着，因为此类制冷设备主要是热驱动的，因此为热电联产提供了额外的用途。尽管DE和三联产系统的一些单独应用已经存在或计划中，但很少有将这些技术结合起来的集成系统。原因之一是基于三联产的分布式能源系统的优化和改进非常复杂，需要对系统组件进行适当的集成。然而，改进现有设计和实现最佳配置的方法通常仍然没有广泛应用。拟议的研究旨在改进基于三联产的集成分布式能源系统的现有和计划设计，以期实现最佳系统和配置。将考虑以下主要因素：效率、经济性和环境影响。预计拟议的研究将带来许多好处，包括改进和优化基于三联产的分布式能源系统的设计和配置，其中效率、经济和环境因素得到了适当的考虑；增加此类系统的应用；向社会提供供暖、制冷和电力服务，提高效率、经济可行性、可靠性和安全性，并减少对环境的影响和退化；并扩大了加拿大经济这一领域的经济增长和就业。
