Abstract

A water and heat hub micro-system and method that provides heat exchange, water consumption, and micro-water-network capabilities, for example, to a single building system or a connected community system for heat and water management. The micro-system is capable of operating independently or may be aggregated with other water and heat hub micro-systems installed to a common network water interface and connected community system.

First claim

What is claimed is:

1 . A water and heat hub micro-system for managing water and heat in water utilized by water appliances comprising:
a thermal bridge comprising:
a controller and at least one mixing valve, the controller controllably connected to the at least one mixing valve;
at least one isolation valve; and
a pump;
wherein the thermal bridge being arranged and disposed to selectively combine water from a fresh water source, a network water interface and a local water source to output product water to one or more water appliances, the water appliances and the thermal bridge being in fluid communication by component supply lines;
wherein the controller operates the at least one mixing valve, the at least one isolation valve and the pump in response to signals corresponding to one or more of temperature, pressure and water quality measurements received from at least one appliance.

2 . The water and heat hub micro-system of claim 1 , wherein the fresh water source is from a water utility, a well, desalination technology, water harvesting device from air, or a combinations thereof.

3 . The water and heat hub micro-system of claim 1 , wherein the network water interface is connected to one or more additional water and heat hub micro-systems.

4 . The water and heat hub micro-system of claim 1 , wherein the local water source is a water storage device.

5 . The water and heat hub micro-system of claim 4 , wherein the water storage device is configured to allow operation of the water and heat hub micro-system in isolation from the fresh water source and the network water interface.

6 . The water and heat hub micro-system of claim 1 , wherein the water appliances are selected from the group of a water source heat pump, a water heater, water treatment system, ice maker and combinations thereof.

7 . The water and heat hub micro-system of claim 1 , wherein the signals are obtained from at least one sensor.

8 . The water and heat hub micro-system of claim 7 , wherein the sensor is selected from a temperature sensor, a pressure sensor, a water quality sensor and combinations thereof.

9 . The water and heat hub micro-system of claim 7 , wherein the at least one sensor includes a temperature sensor, a pressure sensor, and a water quality sensor.

10 . The water and heat hub micro-system of claim 1 , wherein the controller is a component of a control system that provides data and control to the water and hub micro-system.

11 . The water and heat hub micro-system of claim 1 , wherein the controller is a component of a control system that communicates data to or from components or systems outside the water and hub micro-system.

12 . A method for transferring heat and water utilized by water appliances comprising:
providing water to water appliances through a thermal bridge, the thermal bridge comprising:
a controller controllably connected to at least one mixing valve;
at least one isolation valve and a pump, the thermal bridge being arranged and disposed to selectively combine water from a fresh water source, a network water interface and a local water source to output product water to one or more water appliances, the one or more water appliances and the thermal bridge being in fluid communication by component supply lines; and
operating the at least one mixing valve, the at least one isolation valve and the pump with the controller in response to signals corresponding to one or more of temperature, pressure and water quality measurements received from the one or more water appliances.

13 . The method of claim 12 , wherein operating includes obtaining temperature, pressure and water quality measurements resulting from a first operation and operating the at least one mixing valve, the at least one isolation valve and the pump with the controller according to a second operation that is in response to temperature, pressure and water quality measurements resulting from the first operation.

14 . The method of claim 13 , further comprising iteratively obtaining temperature, pressure and water quality measurements and providing operation by the controller in response to the iterative measurements of temperature, pressure and water quality measurements.

15 . The method of claim 12 , wherein the operating includes operating the at least one isolation valve in response to a pressure measurement to isolate the water and heat hub micro-system from one or both of the fresh water source or the network water interface.

16 . The method of claim 12 , wherein the controller is a component of a control system that provides data and control to a water and hub micro-system.

17 . The method of claim 12 , wherein the controller is a component of a control system that communicates data to or from components or systems outside a water and hub micro-system that includes the thermal bridge.
