Integrated energy recovery systems

Title: Integrated energy recovery systems.
Abstract: An energy efficient laundry facility comprises a space heating system, an air conditioning system, a plurality of clothes washers, a plurality of clothes dryers, a hot water storage tank supplying the washers, a source of cold water and conduit means interconnecting the aforesaid. Dedicated heat recovery units are associated respectively with the dryers and employ high temperature dryer exhaust air to heat water for supply to the storage tank. A controller and temperature sensing means regulate the flow of hot water from the dryers to the storage tank. High temperature water is directed to the top of the storage tank and lower temperature water to an intermediate point in the storage tank. Hot water from the dryers is also directed to the space heating system. Each heat recovery unit comprises a heat exchanger, a blower, a water circulation pump, a water temperature sensor, and a dedicated controller. The controller may also include a dryer exhaust pressure monitor, a pressure controller, and a variable speed blower drive. The heat exchanger is of the counterflow type and each recovery unit has its heat exchanger and blower arranged to provide for right angle air flow resulting in a compact unit for mounting atop a clothes dryer. Hot water may also be drawn from the storage tank for use in either an air or hydronic space heating system. ...
