Summary

The characteristics of the radiant floor cooling combined with a dedicated outdoor air system (DOAS) were analyzed. Under the same operating conditions, comparison experiments were conducted to study the dynamic performance and working parameters of the radiant floor cooling system and the combined system, respectively. The changes of different material floor temperature, inner surface temperature of the enclosure, indoor air temperature and relative humidity with time were analyzed under the two experimental conditions. The results show that the adoption of DOAS can enhance the total cooling capacity of the radiant floor cooling combined with dedicated outdoor air system. With proper design parameters (the floor surface temperature of 20-21°C, the inlet air temperature of 21-22°C, and the inlet air velocity of about 1 m/s), this system can operate satisfactorily.
