The existing plant consisted of a combination of heat recovery and cooling only chillers totaling 3000 tons of cooling capacity. The plant provided simultaneous year-round heating and cooling for the Yonge Eglinton Centre Complex. The total efficiency of the plant was 1.22KW/ton. For this work, the challenge was to replace the chillers and modify the plant on the 3rd floor of the office towers with no direct equipment access and without interrupting heating and cooling services to the building.
Our Approach
This project was undertaken in two phases. During the first phase, part of the building envelope was opened to facilitate removal of the cooling-only chiller and installation of the new heat recovery chillers, designed to match closely simultaneous heating/cooling loads during winter months. In phase two, a separate section of the building was opened to facilitate removal of the existing heat recovery chillers and installation of the cooling only chillers; designed to closely match cooling loads during summer months.
Our Results
The new plant consists of a combination of heat recovery and cooling only chillers, totaling 3200 tons of cooling capacity. Total efficiency of the plant has increased to .073KW/ton, client demand load was reduced by 1078KW and power consumption was reduced by 9.9 milKWh.
