Deep Lake Water Cooling: Saving the Earth, one Skyscraper at a Time
In the past we’ve talked about some things that you can do to make your house more energy efficient. Some things are easy, like putting in Compact Florescent light bulbs, while others are on their way in the near future, like your own personal wind turbine.
There’s only so much you can do at home, though, and many of us live in large, air-conditioned office buildings. How could a glass-covered skyscraper possibly use less power for cooling in the summer? If you live in Toronto, it’s easy - just tie into the Deep Lake Water Cooling System.
The system, by Enwave, draws water from Lake Ontario, deep below the surface where it’s always a chilly 4 degrees Celsius. The water runs through huge heat exchangers before making its way into the city’s normal water supply. A separate cooling loop transports water chilled by the incoming lake water to various buildings in the financial district where it is used in the air conditioning system. Here’s a diagram of the system at work.
