Toronto is saving 90,000 Megawatt Hours of electricity by replacing air conditioners with DLWC Systems.

180 Buildings including City Halls, General Hospitals, Scotia banks, Hotels, Data centers in Toronto, Canada are now equipped with the Deep Lake Water Cooling (DLWC) System by ACCIONA Enwave Energy Corporation.

A total of 54 million square feet of landed property in Toronto could save approximately 90,000 MWh (Megawatt Hours) of electricity per year. This is a huge quantity that it can power at least 25,000 residents.

In the depths (83 meters deep) of Lake Ontario, the temperature there in the winter season is almost 39° Fahrenheit (4°C). Three High-Density Polyethylene (HDPE) intake pipes of DWLC(Deep Lake Water Cooling) System with a diameter of 1.6 meters sucks the deep lake water and send it to the central station and filtration plant. This filtration plant has lots of systems such as heat exchangers and valve chambers.

From the intake pipes, the water is passed to the energy transfer station within the city. Heat exchangers in the energy transfer station pick up the energy from cold water and transfer it into a closed circuit. Then the output energy is lifted to the cooling towers and then transferred to the buildings in Toronto.

DWLC System could be able to clear the production of almost 45,000 Kilograms of Chloro Fluro Carbons(CFC), which is a major chemical that has been depleting the Ozone layer for decades.

Throughout the time of construction, special attention was set to minimize the impact on the lake’s ecosystem.

This system will set aside the city’s wealth and provide an effective way of air conditioning.

They invested almost 100 Million USD for this project. Learn More
