ABSTRACT:
A channel beam is characterized by a base portion having upper and lower surfaces thereon with first and second legs depending from the lower surface thereof. A cross piece is disposed between the first and second legs and cooperates with the legs and the lower surface of the base portion to define a region adapted to carry a heat transfer fluid. End caps are provided at the ends of the channel beam to enclose the region and define an enclosed interior volume. Each channel beam is adapted for interconnection with a next-adjacent channel beam such that the upper surfaces thereof define a substantially continuous surface area useful as an athletic playing area. The interior volume of each next-adjacent channel beam may be interconnected through inlet and outlet means so as to define a continuous heat transfer fluid conduction path beneath the athletic playing area so that heat energy incident on the surface area may be transferred to the heat transfer fluid.
