- Abstract
The simulation model of hybrid radiant cooling floor and displacement ventilation air conditioning system was built and analyzed by software EnergyPlus. By comparing the simulation results and experimental data, it is shown that the simulated indoor air temperature and cooling capacity provided by radiant floor was ±7% deviated from the experimental data. Based on the model, with the change of supply air parameters or supply water parameters, the cooling capacity provided by radiant floor and displacement ventilation, surface temperature of radiant floor, indoor air average temperature, AUST temperature were obtained. Combined with the indoor thermal comfort model, when indoor thermal comfort index PMV varied between -0.5 and 0.5, the recommended supply air and supply water parameters were obtained to provide reference for engineering design and application.
