PartagerRésumé
Microencapsulated phase change material (MPCM) slurry is widely investigated recently, and it provides a better kind of media for thermal energy storage in air conditioning systems compared to the conventional media, ice, due to its relatively higher working temperature. Furthermore, it has thermal properties that are appropriate for maximized utilization of nature cooling sources and passive cooling. In this study, a novel MPCM slurry storage system is investigated by combining it with a nocturnal radiative cooling system. The cooling energy consumption and the effect of energy-free nocturnal radiation application were simulated using the energy simulation code ACCURACY and MATLAB model based on hour-by-hour calculations in five typical cities across China. It can be concluded that MPCM slurry appears to be a good medium for the combined application of passive cooling technology and nocturnal radiation in air conditioning systems. The results showed the energy-saving potential in Lanzhou and Urumqi exhibited strong attractions for building energy conservation and emission reduction. Hong Kong has the weakest effect in the five typical cities under the same operating conditions due to the hot and humid climate condition. The present hybrid system is recommended for use in northern west and central China cities where the weather is dry and the ambient temperature is low at night.
