A heat transfer system including a first heat exchange assembly, a second heat exchange assembly, and a heat transfer circuit interconnecting the first and second heat exchange assemblies, the circuit incorporating a working fluid to transfer heat between the first and second heat exchange assemblies. The heat transfer circuit preferably takes the form of a closed loop heat-pipe system. The heat transfer system is operative in a first mode where the working fluid is at or below a threshold pressure and in a second mode where the working fluid is at a higher pressure than the threshold pressure. A pressure regulating device is also provided to increase the pressure of the working fluid above the threshold pressure to effect change of operation of the heat transfer system from the first mode to the second mode. Optionally the pressure regulating device is a pressure vessel having at least one heat transfer surface. An air-conditioning system for conditioning air in a region, including the heat transfer system wherein the first heat exchange assembly is operative to moderate air temperature in the region and wherein the second heat exchange assembly is disposed adjacent a source/sink of substantially constant temperature.
A heat transfer system comprising:
The heat transfer system of any preceding claim wherein the first and second heat transfer assemblies each include a wicking material.
The heat transfer system of any preceding claim wherein the first and second heat transfer assemblies are operative mutually alternatively as evaporators and condensers.
The heat transfer system of any preceding claim wherein the working fluid is arranged to transfer heat to the first heat exchange assembly from the second heat exchange assembly in the first mode.
The heat transfer system of any preceding claims wherein the working fluid is arranged to transfer heat to the second heat exchange assembly from the first heat exchange assembly in the second mode.
The heat transfer system of any preceding claim wherein the pressure regulating device comprises a pressure vessel having at least one heat transfer surface.
The heat transfer system of any preceding claim wherein the working fluid is selected from the group including demineralised water, ammonia, acetaldehyde, ether, pentane, ethyl chloride, and refrigerants R-245fa (1,1,1,3,3 Pentafluoropropane).
A pressure regulating device for a heat transfer system comprising a pressure vessel with at least one heat transfer surface.
A method of controlling a heat transfer system, the system being operative in a first mode where the working fluid is at or below a threshold pressure and a second mode where the working fluid is at a higher pressure than the threshold pressure, the method comprising:
