Outdoor air energy saving design of air conditioning system in data centers

Through the research on air handling processes of data center, compares and analyses the air handling processes of the common data center and the temperature and humidity independent processed data center in detail, and calculates the energy consumption of the two kinds of air handling processes for computer room air conditioning. The calculation results show that, the air handling process with temperature and humidity independent processed can effectively reduce the dehumidification and reheat energy consumption of computer room air conditioning, with huge energy saving potential, although the energy consumption of outdoor air processing is increased. For the large-scale data center air conditioning system, the outdoor air energy saving design with temperature and humidity independent processed has great energy saving significance.
