1. Consider the following scenario: You are the lead mechanical engineer for the new Campus Instructional Facility (CIF) which will feature a ground source ("geothermal") heat pump (and several boreholes drilled in front of Grainger Library). At this stage in the project, you need to select a geothermal heat pump (GHP) capable of heating and/or cooling the new building. Your highly sophisticated energy modeling software informs you that the cooling load is 150 thermal tons (where 1 thermal ton is 3.52 kW) and your heating load is 135 thermal tons. Your selected heat pump manufacturer has a brand of heat pumps with an average COP of 3. CHAN 18-01 (120192781900) Figure 1 Location of CIF and geothermal borefield at the U of IL.
