Top scorer in the contest, which included seven FFA chapters from Berks, Lebanon and Schuylkill counties, was Wade Bernard, son of Mr. and Mrs. Charles Bernard, R 2, Elverson. Dave Noyes, of Twin Valley, placed second and Kevin Gnest was fourth among the 27 con- (The following is reprinted from the December issue of Penn Lines, the monthly publication of the Penn sylvania Rural Electric Association.) HARRISBURG - Earlier this year, Allegheny Electric Cooperative, Inc., entered into a joint research project with the Electric Power Research Institute of Palo Alto, California, to determine how efficiently groundwater source heat pumps perform when installed in rural residential applications in the northeastern United States. As you know, groundwater heat pumps operate by extracting heat out of groundwater for use in beating homes. Groundwater is pumped out of an existing well and is circulated through the heat pump heat exchanger and even tually returned to the ground, typically through a reinjection well. Assisting Allegheny in the project are Valley Rural Electric Cooperative and Bedford Rural Electric Cooperative. Two of their members will have the tests performed in their homes. Briefly, the research project entails installing groundwater heat pumps in the homes of two members, installing instruments and collecting data to analyze the systems’ performance for a comparison with other types of heating systems. To date, the heat pumps have been acquired and installed, the ductwork and conventional beat sources modified and the in strumentation systems installed. As is often the case m research, installation of a sophisticated data collection system necessary to produce practical information has taken a substantial period of tune to perfect. One practical result of the work to date has been learning that groundwater head pumps vary widely in their requirements for groundwater. This fact has already lunited the effectiveness Myer heads Conrad Weiser FFA alumni Kevin Sattazahn Membership in the new FFA alumni group is open to all former active, collegiate or honorary FFA and NFA members, present and former professional vocational agricultural educators, parents of FFA members and others in terested in the FFA.
