Since the major portion of the equipment for the office building was not purchased until needed, the system also reduced capital requirements during construction. In the finished building, the GHP system saved 25,000 square feet in space which otherwise would have been used for maintenance rooms and a 4,000 ton cooling tower. Pinckley Engineering Inc. System Design For the Galt House East Hotel, ground water at 58 F is pumped into a 140,000 gallon reservoir under the mechanical room. This separates the ground water from closed loop circulation systems in the buildings. The closed loops are connected to water source heat pumps which can absorb heat from the loop water or reject heat into the loop water, depending on the requirement of that space.
Any space can have heating or cooling at any time.
The Btu's stored in the reservoir during the day from air-conditioning can be used to heat the building at night. Chemical emissions from cooling tower bleed and boiler blowdown also are eliminated by the geothermal heat pump system. Provided 25,000 more square feet of rentable space. Mr. Al Schneider, the owner, has hundreds of water loop heat pumps connected to boilers and cooling towers which are still operating fine after 20 years. This experience gave Mr. Schneider the confidence to invest heavily in geothermal heat pumps.
