A RATIONAL CALCULATION METHOD FOR THE TEMPERATURE RISE IN COOL-SUPPLY LINES AND A DISCUSSION ON THE SYSTEM EFFICIENCY

In the design of cool-supply system, the TR in the cooling water pipelines is usually estimated by experience, but not by calculation, since the calculated results of TR according to conventional approach is much small than actually tested data. This paper has analyzed the detailed causes that affects the TR values, and also gives a new method for its calculation. By this new method, the paper has also calculated and analyzed the heat efficiency of cool-supply system.
