Evaluation method of cost effectiveness to apply cold thermal storage system to industry based on measured data

摘要

The present invention in real time is measured, considering the industrial chuknaeng system applied to the industry to use a refrigerating machine operating parameters of the industrial refrigeration obtained from the data acquisition device in order to, determine analyzes the installation Feasibility from an economic point of view (e.g., refrigerator power consumption) annually based on the data, calculate the refrigeration load index of the month and day, by comparing the installation investment (fee considerations) compared to operating cost of this, based on current electricity prices of industrial chuknaeng system applicable to systems using inexpensive midnight power (chuknaengsik replacement system) a method for determining the payback time. For the pre-economic evaluation performed for applying chuknaeng system in industry (manufacturers) that are operating the refrigerator investment according to the payback time of making and installation based on it by investment costs compared to operating cost savings as the basis for the calculation result by the present invention It can determine the degree of economic efficiency. Here, the economic evaluation of the payback period may vary depending on the subjective judgment of the customer, just such an algorithm is provided with an indicator of payback period in the economics customer to determine. The present invention is used as, but to perform the economic evaluation is based on the measurement data of the refrigerating machine are movable installed on the industry, introduced before the introduction of chuknaeng system in industry as new, Analysis for economical pre-assessment of the installation, the evaluation method can. In addition, it is possible to deduce the refrigeration industry power load pattern based on the refrigeration load index built by the present invention.
