Retro-fit energy exchange system for transparent incorporation into a plurality of existing energy transfer systems

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.

2. The system of claim 1 wherein said existing first energy transfer sub-system is an air conditioning system.

3. The system of claim 1 , wherein said existing second energy transfer sub-system is a hot water heating system.

4. The system of claim 1 , wherein said energy exchange controller is additionally configured to dynamically adjust determinations for activating or deactivating said energy exchange unit based on different types of input data from different types of equipment.

5. The system of claim 1 , wherein said least one first input comprises input from a temperature sensor connected to at least one connection point of said first set of connection points and for receiving a temperature of coolant associated with said existing first energy transfer sub-system.

6. The system of claim 1 , wherein said least one second input comprises input from a temperature sensor connected to at least one connection point of said second set of connection points and for receiving a temperature of hot water associated with said existing second energy transfer sub-system.

7. The system of claim 1 , wherein said least one second input comprises input from a temperature sensor connected to a tank of a hot water heating system.

8. The system of claim 1 , wherein said first set of valves comprises a first valve connected to a coolant line of an air conditioning system and a second valve connected to said coolant line of said air conditioning system.

9. The system of claim 1 , wherein the energy exchange unit comprises:

an evaporator for evaporating a refrigerant using energy from said excess supply of energy;

a compressor for compressing the refrigerant;

a heat reclaimation unit for supplying energy to said demand for energy; and

a condenser for condensing the refrigerant.

10. The system of claim 9 , wherein the compressor is a screw-type compressor.

11. The system of claim 10 , wherein the compressor is a variable frequency compressor.
