Answer to Question 1

The geothermal heat pump operates on a standard refrigeration cycle, except the geothermal heat pump has an extra glycol loop that circulated through the ground to pick up heat from the ground. The ground heat is used to warm the refrigerant in the outside evaporator and the heat is moved to the building space by the refrigerant.

Answer to Question 2

Change the polarity of either the armature winding or the field winding.
