Recently ASHRAE hosted a Geothermal Water Source Heat Pump Satellite Broadcast. One of the concepts discussed during the presentation was “Centralized Geothermal Heat Pumps.” Centralized Geothermal Systems can be indoors or outdoors and the general concept is to consolidate the multiple individual smaller heat pumps into one or a few larger centralized systems. The advantages to the centralized system are reduced maintenance, reduced or centralized sound, different filtration options and simpler piping and ductwork. Another significant economic impact in our climate zone is that the economizer is back in play. If you look at the graph (left) it displays the different ambient temperatures in Northeast Ohio and the amount of time we spend at those temperatures. What is important to note is the large amount of hours that we spend below our desired indoor condition (72F). In a VAV Geothermal Scenario we can use the outdoor ambient for free cooling during these hours. This result could be more efficient geothermal operation at a lower installed cost. |
