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

顶板辐射供冷是一种舒适度较高的空调方式,系统的供冷能力和顶板表面温度是系统设计和运行的重要参数。实际工程运行参数及其影响因素的测试分析十分必要。本文通过实验测试研究找出影响顶板换热的主要因素,分析了置换通风下的顶板结露问题,提出了将顶板辐射供冷与置换通风配合用于夏季室内供冷除湿的新型空调方式。研究结果可为实际工程的设计、运行参数的选择和系统的可行性分析提供依据和指导。

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.
