Enwave Toronto operates the world renowned Deep Lake Water Cooling (DLWC) system which provides ahighly efficient and low-carbon means of air-conditioning for connected commercial buildings in the city'sdowntown core. Because the DLWC technology is renewable and uses 75% to 83% less electrical energy thanconventional electric chillers, it would be beneficial, in terms of economy and low-carbon means, to utilize andextend the technology further. Therefore, Enwave Toronto is actively perusing alternate technologies such asground thermal energy storage (GTES) to further de-carbonize the district. Enwave Toronto is interested inexploring the feasibility of combining high-efficient refrigeration system, DLWC and GTES to provideincreased cooling capacity during peak cooling in the summer, as well as in exploring the feasibility ofcombining high-efficient heat pump system, data-centre waste heat from their commercial customers andGTES to provide increased heating capacity during peak heating in the winter, on a diurnal basis.If the combinations are feasible through the computer simulations, a parametric study will then be performedfor ranges of relevant parameters in order to establish guidelines for the design of an optimized GTES forshort-term or diurnal cold and hot thermal energy storages. The study would require advanced computationalfacility, subject expertise, and sophisticated computational programs, and this collaboration is intended in thatdirection. This project is part of the company's commitment to sustainable technologies and the development offuture low-carbon district heating and cooling system.This six-month research headed by Dr. Wey Leong of Ryerson University will foster a collaboration betweenRyerson and Enwave, which would be beneficial to Enwave business in Toronto, and will help to build astrong partnership for future research and development activities.

多伦多Enwave运营着世界著名的深湖水冷却（DLWC）系统，该系统为城市downtown核心的互联商业建筑提供了高效且低碳的空调方式。由于DLWC技术是可续签的，并且使用惯用电动冷却器的电能少75％至83％，因此，就经济和低碳手段而言，它将是有益的，可以进一步利用并进一步扩展该技术。因此，多伦多的Enwave正在积极仔细阅读替代技术，例如阳台热储能（GTES），以进一步去碳化。多伦多多伦多感兴趣地探索了探索高效的冷藏系统，DLWC和GTE的可行性通过计算机模拟可行，将对相关参数的范围进行参数研究，以建立设计优化的GTES forshort-term或昼夜冷和热量热能销售的准则。这项研究将需要高级计算效率，主题专业知识和复杂的计算计划，并且这种合作旨在实现。该项目是该公司对可持续技术的承诺的一部分，以及开发不足的低碳区供暖和冷却系统。这六个月的研究由瑞尔森大学的魏尔·莱昂（Wey Leong）博士领导，将促进Ryerson和Enwave之间的合作，这将对多伦多的业务有益，并将帮助发展Astrong Partnerprans和Devutrons研究活动。
