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.

Enwave多伦多运营着世界著名的深湖水冷却（DLWC）系统，为城市中心区的商业建筑提供高效、低碳的空调方式。由于DLWC技术是可再生的，并且比传统的电冷水机组少使用75%至83%的电能，因此在经济和低碳手段方面，进一步利用和扩展该技术将是有益的。因此，Enwave多伦多正在积极研究替代技术，如地面热能储存（GTES），以进一步脱碳区。Enwave多伦多有兴趣探索将高效制冷系统、DLWC和GTES相结合的可行性，以在夏季制冷高峰期提供更大的制冷能力，以及探索将高效热泵系统、商业客户的数据中心废热和GTES相结合的可行性，以在冬季供暖高峰期提供更大的供暖能力，如果这些组合通过计算机模拟是可行的，则将对相关参数的范围进行参数研究，以便为短期或昼夜冷热能量存储的优化GTES的设计建立指导方针。这项研究需要先进的计算设备、专业知识和复杂的计算程序，而这次合作就是朝着这个方向发展的。该项目是该公司致力于可持续技术和开发未来低碳区域供热和制冷系统的一部分。这项由瑞尔森大学的Wey Leong博士领导的为期六个月的研究将促进瑞尔森和Enwave之间的合作，这将有利于Enwave在多伦多的业务，并将有助于为未来的研究和开发活动建立强大的合作伙伴关系。
