Ceiling Radiation and Fresh Air for the Influence of Heating Room Temperature

Article Preview

Abstract:

This paper focus on the study of Ceiling radiation assist with Ground source heat pump air conditioning system which to analysis the operation characteristic by experiment. By testing the ceiling, all round the room air temperature, air temperature, wall temperature and the floor temperature, research the fresh air temperature have influence on the indoor environment temperature and vertical temperature. At the same time, analyzes radiation plate heat transfer per unit area with the end of the air conditioning water temperature and flow relationship. Experiments show that when the room ceiling radiation + natural air to indoor vertical temperature gradient is the largest, the second is ceiling radiation + no fresh air, indoor vertical temperature gradient is the smallest ceiling radiation + preheat air condition, when the system is stable, 2 meters below the vertical temperature difference about 1°C.
