Claim Text:
1. A retrofit energy exchange system for retrofit installation between an existing first energy transfer sub-system and an existing second energy transfer sub-system, the retrofit energy exchange system comprising: a first set of valves for connecting to a first set of connection points of said existing first energy transfer sub-system; said existing first energy transfer sub-system having an excess supply of energy available at said first set of connection points; said existing first energy transfer system connected a first controller; said first controller configured to receive at least one first input for providing data to said first controller; said first controller configured to send at least one output to said existing first energy transfer sub-system for selectively instructing activation or deactivation of said existing first energy transfer sub-system to thereby generate said excess supply of energy; said first controller having a first passive connection point configured to output a first set data received from said at least one first input; a second set of valves for connecting to a second set of connection points of said existing second energy transfer sub-system; said existing second energy transfer sub-system having a demand for energy at said second set of connection points; said existing second energy transfer system connected a second controller; said second controller configured to receive at least one second input for providing data to said second controller; said second controller configured to send at least one output to said existing second energy transfer sub-system for selectively instructing activation or deactivation of said existing second energy transfer sub-system to thereby realize said demand for energy; said second controller having a second passive connection point to output a second set of data received from said at least one second input; and an energy exchange unit connectable to said first set of valves via a first set of conduits; said energy exchange unit connectable to said second set of valves via a second set of conduits; an energy exchange unit controller connectable to said existing first energy transfer sub-system and said existing second energy transfer sub-system to receive said at least one first input and said at least one second input; said energy exchange unit controller configured to activate said energy exchange unit when said energy exchange unit controller determines, based on said at least one first input and said at least one second input, that a present excess supply of energy from said existing first energy transfer system is available to satisfy a present demand for energy at said existing second energy transfer sub-system.
