The SWP converts the existing Btu’s in “cold” seawater into useable energy at high temperatures. The system has a Coefficient of Performance (COP) above 300%, meaning that for every 1 Btu of electricity input into the system to run the system and move the water, 3 Btu’s of useful heat are delivered to the freshwater system.
The Emerson Climate Technologies patented system of compressors and high temperature heat pumps provide a viable alternative to power District Heating without requiring the burning of fossil fuels. Furthermore, the refrigerant used does not affect the ozone in any way. The entire process is 100% renewable because it uses the heat contained in seawater which is in abundant supply.
The heat energy source for the entire District Heating is harvested from the ocean where it was heated by the sun. In essence the ocean water is a solar collector with a zero carbon load. As long as there is sun and seawater, the District Heating District can produce the heat to warm the businesses and homes in Juneau.
