The air-conditioning systems served for high-tech cleanrooms, requiring strict space temperature, humidity and particle concentration controls, are usually energy-intensive, which consume the same magnitude of energy as that of data centers. Their system performance is strongly climate- and weather-dependent, which didn’t receive enough attention as data centers. Therefore, this study has evaluated the year-round energy performance of high-tech cleanroom air-conditioning systems in different climate conditions. A typical high-tech cleanroom air-conditioning system, i.e., MAU (make-up air unit) +DCC (dry cooling coil) +FFU (fan filter unit) system, is selected to examine the system performance using the EnergyPlus/Matlab platform. The results show that the monthly energy performance of the system could be modeled as a function of the weather condition. The system has the lowest energy consumption during the transition seasons throughout the year. It also shows better energy performance in hot and mild zones. The studied results could provide a general understanding of the energy performance of high-tech cleanroom air-conditioning systems in different climate and weather conditions.
