Résumé

DOAS (dedicated outdoor air system) combined with CRCP (ceiling radiant cooling panel) has been getting more applications around the world due to its advantages on thermal comfort and human health. However, condensation control of ceiling radiant cooling panel is usually a big concern when this system is applied, especially in hot and humid regions. This paper focuses on the study of the control strategies of multi-zone DOAS + ceiling radiant cooling panel system, intending to promote the further development and application of this hybrid system. Firstly the allowed minimum inlet water temperature of radiant cooling panels is investigated and a formulation is given to determine its value. Then, the paper proposes a practical control method for multi-zone DOAS +CRCP system applied in hot and humid regions, based on the study on allowed minimum inlet water temperature of CRCP. The control method is applied in a small project with DOAS+CRCP system installed in an office space with 172.4 sq.m. floor area and four thermal zones and test are conducted on two typical weather data. The test results show that indoor air temperature and humidity can be very well controlled while condensation is successfully avoided.
