Remotely located Canadian communities' often have difficulty growing local foodstuffs due to their harsh**climates. Combined with the lack of transportation infrastructure and the long distances to other communities,**this limits access to fresh produce and jeopardizes food security. Consequently, Cindar Power Developments**Inc. (CPDI) is developing a new high-performance sealed greenhouse for use in northern climates to give these**communities the capacity to grow their own vegetables. The new greenhouse will be powered by a**high-efficiency, bio-fueled co-generation power plant that will also supply the community with electricity and**heat. A key challenge of sealed greenhouses is the creation of large dehumidification loads that need to be met**to maintain optimal plant growth. A promising method of servicing these loads are through the use of liquid**desiccant (LD) dehumidification systems that absorb the excess moisture in a salt solution. Heat, rather than**electricity is used to regenerate the salt solution allowing for continuous operation. This uses less electrical**energy than traditional vapour-compression dehumidifiers. This heat will be supplied from the high-efficiency**co-generation plant. This NSERC Engage Plus grant continues the work of researchers at Queen's University**and CPDI that was completed under an initial Engage grant which studied the feasibility of the LD system and**the greenhouse design. The Engage Plus extension will allow for the refinement and validation of the computer**model, and contribute to the establishment of a pilot plant in a North-Western Ontario community in the near**future.**

由于气候恶劣，偏远的加拿大社区通常很难种植当地的食物。再加上缺乏交通基础设施和距离其他社区很远，**这限制了新鲜农产品的获取，并危及粮食安全。因此，Cindar Power Developments**Inc.(CPDI)正在开发一种新的高性能密封温室，用于北方气候，使这些**社区有能力种植自己的蔬菜。新的温室将由一个高效率的生物燃料热电联产发电厂提供动力，该发电厂还将为社区提供电力和热量。密封式温室的一个关键挑战是产生大量的除湿负荷，**以保持植物的最佳生长。满足这些负荷的一种有前景的方法是使用液体**除湿系统，该系统吸收盐溶液中的多余水分。使用热量，而不是**电来再生盐溶液，从而实现连续运行。与传统的蒸汽压缩除湿器相比，这种除湿器使用的电能更少。这些热量将由高效率的热电厂提供。这笔NSERC Engage Plus补助金继续了女王大学**和CPDI的研究人员的工作，这项工作是在一项初步的Engage补助金下完成的，该补助金研究了LD系统和**温室设计的可行性。Engage Plus扩展将允许改进和验证计算机**模型，并有助于在不久的**将来在安大略省西北部社区建立一个试点工厂。
