Seawater District Cooling and Lake Source District Cooling

ABSTRACT Seawater district cooling (SDC), and the similar lake source district cooling (LSDC), is a technology which is beginning to make a significant impact on energy conservation as a viable alternative to conventional central air conditioning systems. The principles of SDC can be implemented in any region of the world with a sufficient cold water resource located in close proximity to a dense central air conditioning load. SDC systems have been developed in all climates and locales ranging from Stockholm, Sweden, to Kona, Hawaii. Implementation of SDC principles in the design, development, or conversion of central air conditioning systems has proven to save in excess of 85 percent of the energy typically required for conventional air conditioning. With escalating and volatile energy prices, SDC systems provide a sustainable and reliable means of stabilizing energy costs for the air conditioning component of a building or facility's energy budget.
