412 Study on the energy-saving effect by the free cooling system using an absorption refrigerating machine

The recent expansion of the internet network and rapid advancements in information and communication technology are expected to lead to a significant increase in power consumption and the number of data centers. However, these data centers consume a considerable amount of electric power all year round, regardless of working days or holidays; thus, energy saving at these facilities has become essential. A disproportionate level of power consumption is concentrated in computer rooms because air conditioners in these rooms are required to operate throughout the year to maintain a constant indoor environment for stable operation of computer equipment with high-heat release densities. Considerable energy-saving potential is expected in such computer rooms, which consume high levels of energy, if an outdoor air-cooling system and air conditioners are installed. These systems can reduce the indoor space temperature by introducing a relatively low outdoor air temperature. Therefore, we studied the energy-saving effect of introducing an outdoor air-cooling system in a computer room with a disorganized arrangement of servers and an inadequate air conditioning system in a research complex in Korea. The findings of this study confirmed that annual energy savings of up to approximately 40% can be achieved.

The Heat Balance

In order to evaluate the energy-saving effect of Distributed Cooling System (DCS) analytically, the heat balance model of DCS in a TBS is established and then dynamic simulation is employed. The numeral results show that DCS has much better energy-saving effect than traditional air conditioning (AC) and the energy-saving effect is steady all year round.

Saving Effect

Combined system of radiant cooling and dedicated outdoor air system (DOAS) has advantage in energy-saving and thermal comfort. In order to investigate the energy saving potential of the system under different climate conditions in China, Tianjin, Shanghai, Guangzhou, Chengdu and Xi’an were selected, where summer energy consumption of the combined system and fan coil + fresh air system in reference building was calculated with BIN method respectively. The results show that radiant cooling system has better performance in energy saving than fan coil system by saving of 12-16%. The system operation time and outdoor climate are main factors influencing energy saving effect.
