The Numerical Simulation And Experimental Study Of Heat And Mass Exchange In Sprayroom

With the development of society, the request of modern living and working environment for people is increasing, therefore, the resulting energy consumption is also growing. There is a growing tension today, it is a efficient way to improve the efficiency of a variety of devices to solve this problem of energy. Energy crisis, the greenhouse effect, as well as restrictions on the use of CFCs also makes the development of mechanical compression and absorption refrigeration restrict. Therefore, how to use low energy consumption and pollution-free air conditioning cooling method has become a very important development direction.Spray room, that use of water and air in direct contact to achieve the regulation of air temperature, humidity, the way has aroused widespread concern, meanwhile, the spray room is advantage of dealing with large amount of wind. Therefore, there are many new applications in spray room in the present situation. Many domestic scholars carried out a lot of research for spray room, but many problems are not resolved.Meanwhile, it is carried out that use limited test methods'application with the studies of spray indoor heat and moisture exchange process.In this paper, based on the research of other scholars, it analyzed the indoor heat and moisture exchange process with the method of numerical simulation, at the same time, it was validation for the application part of the test for numerical simulation results; Finally, the structure of the spray room was optimized as the these analyzes results.Main contents of this article:(1) For the same structure and size of the spray room, if the air flow section is improved, it can increase the heat and moisture exchange and improve the efficiency of the spray room;(2) It is conducive to spray the indoor heat and moisture transfer, if the initial temperature of air and water droplets is increased;(3) In the case of low water pressure, water spray on the interior is conducive to spray the indoor heat and moisture transfer of water and air; in the case of high water pressure, water spraying against the spray room is conducive to heat and moisture exchange. For the different dimensions of spray room, the water pressure limits are different;(4) For multi-row spray nozzle of the spray room, row spacing have great impact on heat and moisture transfer. When the air flow and water pressure is high, it is benefit to spray the indoor heat and moisture exchange process due to increased row spacing;The study of this topic provide a more convenient research methods - using FLUENT simulation method, meanwhile, the structure of the spray room has been optimized and hoped that the air-conditioning equipment can have a better practicality and economy.
