1. You are the lead mechanical engineer for a new campus instructional facility that will feature a ground-source ("geothermal") heat pump, or GHP. The heat pump's evaporator (or condenser) will receive hot (or cool) water from several boreholes drilled in front of the building. At this stage in the design process, you need to select a GHP capable of heating and/or cooling the new building. Sophisticated energy modeling software informs you that the cooling load is 150 tons, and the heating load is 135 tons. Note: 1 thermal ton is equivalent to 3.52 kWth. Your selected heat pump manufacturer has a brand of heat pumps with a mean COP of 3
