Description

Technical field [0001] The present invention relates to a modeling device, a modeling program, a simulation device and a simulation program that use a thermal balance model to predict the energy consumption of the device, and a thermal balance model utilization method and thermal balance model utilization system including these . Background technique [0002] In the past, in facilities (e.g., supermarkets, convenience stores) that house multiple devices (e.g., air conditioners, refrigerators, freezers, and freezer / refrigeration showcases), it has been known to be used as a method of predicting the energy consumption of each device The method of the heat balance model is introduced. [0003] The heat balance model is constructed by calculating the heat load to the facility or the heat balance to the equipment, and calculating the coefficient of performance (COP; Coefficient of Performance) of the equipment. [0004] Specifically, by dividing the glass windows, outer walls, or roof...
