Once the steam enter the building, it goes into a radiator, turns into water and gives off heat in the process--the same type of reaction that causes third degree burns from steam. When the water vapor contracts into a more dense state--from gas to liquid--it gives off energy in the form of heat. Once the steam condenses to water after it has served its heating purpose, it is sent back to the plant through the same system of underground lines and tunnels...
...same time, because the plant is not located directly on campus, the pipes lose some heat as the steam travels through the underground system. Engineers must also worry about the thermal expansion of underground pipes through junctions. "In 300 feet, [the pipes] may expand six to nine inches when they go from room temperature to steam at 400 degrees Fahrenheit," says Hawkes...
...Once the heat reaches the pipes outside the building walls, control moves out of the hands of Engineering and Utilities into the domain of Facilities Maintenance Operations, and Hawkes can take a break...
...Water is cooled down with a heat exchanger using freon as refrigerant," he says. "In the chiller, gas is compressed, and then as it expands, the cooling effect results...
