Experimental Research on the Lower Energy Consumption Construction of Radiant Ceiling Cooling with Displacement Ventilation

The radiant ceiling cooling is a technology with higher comfortable degree in the air-conditioning field.The cooling capacity and the surface temperature of the radiant ceiling are the important factor of the design and operation in the air-conditioning system.The test analysis for the function factor and influencing factor is very essential in practice.The primary factor of influencing radiant ceiling cooling is discovered through test research experiment in this paper, the ceiling dew problem is analyzed in the displacement ventilation situation, and the new air conditioning system-the radiant ceiling cooling system combined with displacement ventilation was proposed.Results in the paper provide basis and guide for the design of the project, the selection of parameters and feasibility of the system.
