Abstract

In the thermal buffer 1, water is maintained at a relatively low temperature (40 degrees F) in a well insulated tank via thermoelectrics. If one or two of the following events occurs; (1) the customer water flow stops, (2) the customer water temperature rises, (3) the ambient temperature rises, or (4) all the blowers fail; the system water temperature 3 will rise beyond the desired temperature. A controller circuit will open solenoid valve 4 allowing a controlled amount of cool water to mix with the returning hot fluid.

Thermal Buffer

In the thermal buffer 1, water is maintained at a relatively low temperature (40 degrees F) in a well insulated tank via thermoelectrics. If one or two of the following events occurs; (1) the customer water flow stops, (2) the customer water temperature rises, (3) the ambient temperature rises, or (4) all the blowers fail; the system water temperature 3 will rise beyond the desired temperature. A controller circuit will open solenoid valve 4 allowing a controlled amount of cool water to mix with the returning hot fluid.

The controller simultaneously signals the computer to store all the modified information in a nonvolatile memory, since the computer will lose cooling in a few minutes. The length of time the machine will be provided with the buffer cooling depends on the buffer size, the temperature difference between the supply temperature and the buffer temperature, and the system heat load.

In the absence of the thermoelectric cooling, the physical size of the thermal buffer 1 is prohibitive. For example, the thermal buffer would have to be three times as large to provide the required cooling when it stores the water at 75 degrees F rather than 40 degrees F.
