The Optimization of the Personalized Fresh Air Ventilation and Individualized Radiation in the Hospital Ward

摘要

To a hospital ward, the temperature and humidity independent control system (THICACS) is very suitable to be applied. However, because of its expensive initial investment, the application of this kind of air-conditioning system is still limited. Based on the conventional THICACS, this paper adopt personalized ventilation and radiation in a triple ward to improve the performance of HVAC system. By simulating the distributions of several key parameters such as temperature and PMV, comparisons and validations are made between conventional and personalized THICACS. The result shows that the amount of the radiant panels are reduced almost 33.8% in personalized ventilation and radiation system. We can draw a conclusion that, by implementing the personalized ventilation to fresh air and the individualized radiation to terminal devices, we can reduce the laying area of the radiant panel and improve indoor comfort levels, which shows a great significance in advancing economics and energy-saving performance of THICACS.
