TEMPERATURE MEASURING METHOD, TEMPERATURE CONTROL SYSTEM, AIR FLOW MEASURING DEVICE, AND HEATING VALUE MEASURING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a temperature measuring method, an air flow measuring device and a heating value measuring device for a computer room using an optical fiber which can measure a temperature distribution of the computer room efficiently with sufficient accuracy.

SOLUTION: A first optical fiber 24a is installed so as to pass near a grill a of a free access floor 15 and near an inlet port b inside a rack 11 in which a peak temperature is a relatively low temperature. Further, a second optical fiber 24b is installed so as to pass near CPU c in which the peak temperature is a relatively high and near an exhaust port d and near a ceiling e outside the rack. Thereby, a temperature difference of adjacent measuring points becomes small, therefore excellent measuring accuracy is obtained.
