The Energy Centre
The 230 m2 (2,500 square foot) Energy Centre building for the Drake Landing Solar Community (DLSC) is the heart of the district heating system. Located in the corner of the community park, it houses the short-term heat storage tanks and most of the mechanical equipment such as pumps, heat exchangers, and controls. The solar collector loop, the district heating loop, and the borehole thermal energy storage loop pass through the Energy Centre.
Approximately 70 percent of the floor space is filled with two large, horizontal, insulated water tanks, each 3.8m (12 feet) in diameter and 11.4m (38 feet) long. The water temperatures within these tanks are stratified to improve the overall efficiency of the system.
The front room of the Energy Centre contains the pumps, valves, heat exchangers, expansion tanks, and other equipment necessary to operate and control the energy system.
