Abstract:
1. A method of assembling a ground source heat pump system, comprising: a. providing a ground source heat pump system comprising at least one heat pump and a first heat exchanger loop using a first water/glycol mixture to exchange heat between each heat pump and at least one underground heat exchanger; b. providing an air/liquid heat exchanger having an outdoor air primary side to exchange heat between outdoor air and a primary side of a liquid/liquid heat exchanger; c. providing a second heat exchanger loop using a second water/glycol mixture on a secondary side of the liquid/liquid heat exchanger; d. interconnecting the first heat exchanger loop and the second heat exchanger loop such that either of them connects to the ground source heat pump system; and e. providing a controller interconnected to each of the first and second heat exchanger loops to selectively connect which of them is connected to the ground source heat pump as a function of at least: (1) heating/cooling season; (2) space temperature set point; and (3) whether ambient temperature exceeds ground temperature or vice versa.
