Abstract

Provided is a thermal energy compensator providing relatively constant temperature water to a distributed cooling system.

Claims (14)

1 . A thermal energy compensator for use in conjunction with an air conditioning unit, comprising:

a shell and tube structured heat exchanger flooded with water in an initial condition; and

a vacuum pump operably connected to an inlet of a turbine engine and to an exhaust fan;

wherein the thermal energy compensator is connected in line with the air conditioning unit; and the thermal energy compensator operates subject to a plurality of feedback loop systems;

whereby incoming water is provided at a supply temperature, and outgoing water is provided at a return temperature; and

when a demand for cooling exceeds a native cooling capacity of the air conditioning unit, the thermal energy compensator provides additional cooling capacity.

2 . The thermal energy compensator of claim 1 , wherein the feedback loop systems comprise at least one member selected from the group consisting of:

pressure on a shell side of the shell and tube structured heat exchanger;

current cooling load and available excess capacity of the air conditioning unit;

magnitude and starting point of a sporadic load; and

the return temperature.

3 . The thermal energy compensator of claim 2 , wherein the return temperature is maintained at a constant desired level.

4 . The thermal energy compensator of claim 1 , wherein the supply temperature is lower than the return temperature.

5 . The thermal energy compensator of claim 4 , wherein the supply temperature is 44° F. and the supply temperature is 50.6° F.
