Questions 2:
The undisturbed deep earth temperature of the ground at a depth of 50 feet beneath a property is approximately equal to:

a) the average annual air temperature plus 2°F

b) the average annual water temperature in the nearest
         surface water body to the property

c) the average annual summertime air temperature divided
         by four.

d) one degree Fahrenheit per foot times the depth in
        feet of the vertical ground loop borehole

a) True

b) False

Question 7:
What percentage of the sun’s energy is absorbed by the ground on an annual basis?

a) 37 percent

b) 41 percent

c) 47 percent

d) 53 percent
 

Question 8:
Standard ground source heat pumps cannot be used to produce electricity.

a) True

b) False

Questions 9:
The vapor compression refrigeration process is fundamental to the operation of GSHPs. It was first demonstrated in what year?

a) 1748

b) 1834

c) 1928

d) 1948

Questions 10:
Which statement below is true?

a) A closed loop system exchanges ground water with

         the refrigerant loop to transfer energy and an open loop
         system dumps ground water to either a surface water body
         or second well.

b) A shallow horizontal closed loop configuration uses
         groundwater to exchange heat energy with the GSHP        
         refrigerant loop.

c) An open ground loop system can pump groundwater
         directly to the refrigerant loop to exchange energy but a
         closed loop system pumps water or an antifreeze solution
         to the refrigerant loop.

d) A "Pump and Dump" loop is a common description for an
         outdoor vertical closed loop configuration
