The Research And Application Of Ceiling Radiant Cooling Panel

Radiant cooling ceiling (RCC) is popular in oversea primarily European countries. It is widely used at high level buildings that need ceiling such as offices, hospitals and schools. Due to its limited cooling capacity, RCC is often combined with mechanical ventilation systems. There are two kinds of ventilation systems for us to choose: DOAS (Displacement and Dedicated Outdoor Air System), between which DOAS is fitter for native use. When radiant cooling ceiling is used as terminal device of DOAS, this system will perform excellently in affording good comfort, low operation noise, higher air quality by elimination of return air and condensation, what's more, the module panel design makes fitment and repair works more convenient. These advantages satisfy all personal demands for air conditioning system.However, the development of RCC suffers setbacks and leaves bad impression in people's mind as easily get condensation, high first cost and small cooling capacity. Modern RCC overcomes the above defects. This article explains in detail to get rid of those old biases and prove the application of RCC is possible.As the composing part of RCC, RCP (Radiant Cooling Panel) focuses on enhancing its heat conduct performance and cooling capacity. We can take the RCP as fin structure, and then build a computation module to get its actual cooling capacity at application occasions. Because RCP can be used in complicated situations that will result in different performances, merchant products should be sold with lab testing results with national standard.Till today, there is no native RCP producer in our country. The expensive price of imported RCP becomes the obstacle of application of RCC system. To our joy, we have lately developed a kind of RCP of completely new simple frame. According to the test results of Xi'an Jiaotong University, this new panel trebles cooling capacity compared with imported ones. The most worth noticing thing is the adoption of superhydrophobic technique in the panel surface processing. After getting on this special membrane, no water is able to stick on the panel surface even in extreme situations. Thus condensation is cleverly resolved and simplifies the control system for panel water loop.
