radiant floor cooling

As a comfortable and energy-efficient air conditioning system, the application of radiant floor heating system is increasing greatly used in the north of China. Now, more and more people begin to be aware of the problem of thermal comfort degree in radiant floor cooling room. This study aims at developing a radiant floor cooling system using the existing radiant floor heating system. Unlike an all-air cooling system, the radiant floor cooling system could remove the cooling by convection and radiation.

In this study, the concept of the Hybrid air-conditioning system utilizing convection and radiation heat exchange will be suggested. In this paper, the heat removal characteristics of Hybrid air-conditioning system will be described by theoretical review and experimental methods. Also the ratio of cooling load removed by Hybrid air-conditioning system could be divided as radiation and convection heat exchanges. The methods could be used to system design of Hybrid air-conditioning system.
