A Study Of Cooling Ceiling System

The cooling ceiling system is being used in many countries. It has been studied for many years. This paper preview its?great potentiality in the future. This paper reports the construction and operating of cooling ceiling system in our test room. As a whole, the author pays emphasis on both experiments analysis and theoretical analysis. The equipment includes data collection system, cooling ceiling and outdoor air sYstem. The experiment includes six stages: observation of dew point, the performance of cooling ceiling, flowrate adjustment, fluid temperature adjustment, outdoor air system, plotting of temperature distribution. According to the results of the experiment, the author calculates cooling performance of the cooling ceiling. Analysis the air conditioning effectiveness through plotting the temperature distribution. Analysis the extent of energy saving through describing body sensation. Analysis cooling ceiling automatic regulation. Calculate cooling ceiling theoretical performance. Propose perative temperature as the control variable instead of ir temperature which has many advantages.
