Abstract


As people’s living standards are improved,the use of heating,ventilating and air-conditioning systems is becoming more and more widespread,high indoor air quality,thermal comfort,energy saving is becoming more and more important .To the traditional air-conditioning system,more comfortable means more energy consumed,only environmental protection,energy saving,comfortable air-condition systems can meet the requirements of the modern buildings. Capillary Radiation HVAC system and displacement ventilation system in proving indoor air quality and the superiority of Capillary Radiation HVAC system in improving thermal comfort as well as its saving energy efficiency,which attracts people’s attention. This article sets up a radiation mold of ceiling and displacement ventilation of an air conditioned room,anther radiation mold of wall and displacement ventilation of an air conditioned room,the article simulated the indoor thermal and velocity distribution,under different conditions,by using the software CFD. The article evaluates the door air distribution comfortable feeling .the influence on the air flow is analyzed where some factors such as the heat source of south window,velocity and temperature of air supply ,temperature of capillary Radiation are given,which provides a reference for appraisal of the heating comfort characteristic of the system. at last using the concept of entropy and exergy,the article analyzes the irreversible loss of capillary panel and the displacement ventilation.
