Abstract: An energy recovery system and method for laundry systems that transfers heat from warm exhaust air to intake air. The system and method includes a thermal wheel adapted to absorb heat from an exhaust air stream and discharge heat to an intake air stream for preheating the intake air. The system and method further includes a lint management system for clearing or otherwise managing lint buildup on the thermal wheel, and a bypass damper for admitting non-preheated intake air, particularly for use during a cooldown cycle.

Abstract: A service building (10) having a base assembly (20) formed with a perimeter support portion (21) and a floor portion (22). The perimeter support portion (21) utilizes weight bearing side rails (23) with one or more transverse, weight supporting beam means (35) extending between at least one pair of opposite side rails (23). Decking sheets (30), insulating mats (44) and sump pans (48) are supported from the side rails (23) and beam means (35). Wall panel assemblies (60) are secured to the perimeter support portion (21) by sill connector assemblies (78). Post assemblies (105, 135 and 165) between the wall panel assemblies (60) secure adjacent wall panel assemblies together. A roof (not shown) may be secured to the service building (10) using connector assemblies substantially identical with the post assemblies.
