There is provided systems and methods for transporting heat away from galley refrigeration equipment or other heat-generating systems such as avionics, power electronics, or in-flight entertainment units, via a potable water system. The potable water system transports heat more effectively and more efficiently than other systems used to date.

1. A system for cooling a compartment or device on an aircraft, comprising: (a) a potable water tank on-board the aircraft for providing drinkable water;(b) an air chiller unit located remotely from the compartment or device to be cooled;(c) a first air flow line to deliver chilled air from the air

1. A system for cooling a compartment or device on an aircraft, comprising: (a) a potable water tank on-board the aircraft for providing drinkable water;(b) an air chiller unit located remotely from the compartment or device to be cooled;(c) a first air flow line to deliver chilled air from the air chiller unit to the compartment or device to be cooled;(d) a second air flow line to deliver warmed air from the compartment or device to be cooled back to the air chiller unit;(e) a first water supply line to deliver potable water from the potable water tank through the air chiller unit so that the potable water absorbs heat from refrigerant in the air chiller unit;(f) a second water supply line to deliver heated potable water from the air chiller unit to a heat exchanger unit, where heat from the warmed water is transferred to air; and(g) a third air flow line to deliver the warmed air outside the aircraft. 2. The system of claim 1, further comprising a heat exchanger in the air chiller unit that comprises an annular configuration of three concentric tubes for directing potable water and refrigerant flow, and for providing a channel for leak detection. 3. The system of claim 1, wherein the air chiller unit comprises an evaporator comprising a refrigerant fluid that extracts heat from the warmed air that is received from the second air flow line, wherein extracting heat from the warmed air causes the warmed air to become chilled air that is transported back to the compartment or device to be cooled by the first air flow line; and a condenser that extracts heat from the refrigerant fluid and directing the heat into the potable water. 4. A system for cooling an area or device in an aircraft, comprising: a potable water system comprising: a water tank for containing potable water;a first supply line for transporting the potable water from the water tank to a vapor compression refrigerating unit; anda second supply line;the vapor compression refrigerating unit located remotely from the area to be cooled, the vapor compression refrigerating unit comprising: an evaporator comprising a refrigerant fluid that extracts heat from warmed air that was warmed by the area or device to be cooled and that is received from a return air ducting line to cause the warmed air to become chilled air that the vapor compression refrigerating unit provides to an air ducting line for transporting the chilled air to the area or device to be cooled; anda condenser for extracting the heat from the refrigerant fluid and of directing the heat into the potable water received from the first supply line, such that the potable water is provided from the vapor compression refrigerating unit at a higher temperature that a temperature of the potable water received by the vapor compression refrigerating unit,wherein the second supply line transports the potable water at the higher temperature to an air-to-water heat exchanger that absorbs heat from the potable water at the higher temperature into air such that the potable water exits the air-to-water heat exchange at a lower temperature than the temperature at which it entered the air-to-water heat exchanger, such that the potable water stays contained in the first and second supply lines and does not come in direct contact with components of the vapor compression refrigerating unit; and an outflow valve for expelling from the aircraft the air heated from the higher temperature potable water. 5. The system of claim 4, wherein the area is a galley in the aircraft. 6. The system of claim 4, further comprising a heat exchanger in the vapor compression refrigerating unit that comprises an annular configuration of three concentric tubes for directing water and refrigerant flow, and for providing a channel for leak detection. 7. The system of claim 4, wherein the water tank provides potable water for use to wash hands of a person. 8. A system for performing cooling of a compartment or device on an aircraft, comprising: (a) an air chiller unit located remotely from the compartment or device to be cooled;(b) an air ducting line that transports chilled air from the an air chiller unit to the compartment or device;(c) a return air ducting line that transports warmed air back to the an air chiller unit;(d) a supply line that directs potable water from a potable water tank to the an air chiller unit, such that the potable water stays contained in the supply line and does not come in direct contact with components of the air chiller unit; and(e) a condenser system in the air chiller unit that directs heat from the warmed air into the potable water, such that the potable water serves as a heat sink for heat transport. 9. The system of claim 8, wherein the heated potable water is transported to an air to water heat exchanger that receives air from other areas on the transportation vehicle and transfers heat from the heated potable water to the received air. 10. The system of claim 9, wherein heat from the air is expelled from the aircraft and the potable water is transported back to the water tank.
