In recent years, the internet services industry has been developing rapidly. Accordingly, the demands for compute and storage capacity continue to increase and internet data centers (IDCs) are consuming more power than ever before to provide this capacity. With large scale power usage comes the large price tag of paying for that power. With growth trends increasing and development expanding, IDC owners...
In recent years, the demand for compute capability has increased rapidly, and data centers all over the world are consuming much more power than before. Data centers across the globe consume around 100 GWh and it is expected to increase by 30% by 2016. In 2012, the increase in data center energy consumption in the United States and China was 800MWh and 500MWh respectively, based on Forest & Sullivan...
The compression process can approach the isothermal one when compressors are cooled in the compression process, and the compression work can be reduced. The paper presents a special external cooling structure for scroll refrigeration compressor. A mathematical model is established to simulate the compressor. All of boundary conditions in heat transfer model are set to coincide with the real operation...
Desiccant evaporative systems are heat driven at moderate temperature and are usually coupled with solar collectors or with waste heat. The performance of desiccant systems is very sensitive to outside conditions and to the efficiency of the system components. In this paper the impact of these factors on the performance of two configurations of desiccant systems is investigated through simulation...
