PERFORMANCE EVALUATION APPARATUS OF TURBO REFRIGERATION DEVICE

摘要

PURPOSE: A performance evaluation apparatus of a turbo refrigerator is provided to calculate a plane COP(Coefficient Of Performance) by a sequential calculation. CONSTITUTION: A performance evaluation apparatus of a turbo refrigerator comprises data acquisition means(101), a memory storage device(102), and calculation means(103). The data acquisition means acquires operation data of a turbo refrigerator as input data. The memory storage device saves a plan COP estimation formula in which a correction value correspondent to a loss generated in a practical circumstance is added to a calculating formula of a practical ideal COP using a COP property of the reversed Carnot cycle. The calculation means estimates the plan COP at the current operating point by using the operating data acquired by the acquisition means and the plan COP estimation formula saved in the memory storage device. The correction value comprises first and second correction values. The first correction value is calculated by a first calculating formula having a load factor of the turbo refrigerator as a variable. The second correction value is calculated by a second calculating formula having a heat difference between temperatures in outlets for a cooling water and cold water.
