Abstract: An energy management apparatus, energy management method, and non-transitory tangible computer readable medium thereof are provided. The energy management apparatus receives a plurality of first operation data and environment data, derives a plurality of simulated energy data through energy simulation based on the first operation data and the environment data, calculates an error value between a real environment value and a simulated environment value of the simulated energy data, decides a simulation objective value according to the error value, and decides a plurality of second operation data through energy simulation based on a search algorithm and the simulation objective value. The first operation data correspond to a first time interval, each of the first operation data corresponds to one of a plurality of devices, and the second operation data correspond to a second time interval, and each of the second operation data corresponds to one of the devices.

Abstract: A refrigerant cooling system for an electronic apparatus and the method thereof are provided. An enclosure is set with a fan on one side thereof; the enclosure is set with an opening on one side thereof. The enclosure is set with an electronic substrate inside with other electronic devices. The electronic substrate is set with a middle-temperature evaporator with an input end and an output end, in which the refrigerant is filled into the input end. The input end is set with a throttling device. The output end is set with a throttling device connecting to a low-temperature evaporator. The low-temperature evaporator is set with a condensed water drain-pan at a bottom side thereof and the condensation water drain-pan is connected to a drain pipe. The pipe of the output end of low-temperature evaporator is connected to a receiver or a compressor of a refrigerating system for a compression cycle.
