Simulation and Optimization of the Temperature and Humidity Independent Control Showcase

摘要

A new kind of showcase with temperature and humidity independent control is introduced in this paper to reduce the energy consumption of the showcase's air-conditioning system. Computational Fluid Dynamics was employed to investigate this new showcase's temperature field; more attention was focused on the effects of inlet's temperature and velocity. It is found that inlet temperature is the key factor affecting the temperature field. The lower the inlet temperature is, the less the effect on the showcase is. It is also found that the inlet velocity's effect on the showcase's temperature field is little. However, to satisfy the cultural relics' preservation, the inlet velocity should be keep at a low value.
