Simulation And Optimization Of Air Distribution Around Air Conditioning Cooling Towers

Air conditioning cooling tower is an important part of central air conditioning system,also the energy-consuming equipment in air conditioning system.As a result,the operation of the cooling tower has a great influence on the entire air conditioning system.At present some High grade buildings in order to ensure that the overall appearance of building is beautiful and reduce the noise emitted by the cooling tower operation on the surrounding environment,there put the cooling tower in indoor.Cooling tower group put in indoor,which could lead to a bad ventilation condition of cooling towers.Cooling tower produce a large amount of heat,while can not be emitted to outdoor.Thus affect the cooling tower heat transfer,which affect the refrigeration and heating of air conditioning system.When cooling tower put in the interior,this subject adopts the way of forced ventilation exhaust air.Therefore,indoor cooling tower running affects the entire central air-conditioning system.First this topic are simulated the air distribution of cooling tower group on indoor,under the condition of meet the requirements of exhaust air of each cooling tower get pressure difference of each cooling tower,can get the power needed for the normal operation of each cooling tower equipment,to provide theoretical reference for the fan selection,at the same time it can be seen that the indoor cooling tower group no larger eddy current of air distribution,will not lead to a heat accumulation.Due to outdoor parameters will change with the seasons change,so the refrigeration duty of building will also change,so the number of cooling tower open sets with the corresponding change.However,open how many sets of cooling tower to achieve the best effect,this topic presents a feasibility study method of the numerical simulation analysis.In this topic in the case of closed 4 sets of cooling tower,and chose four kinds of typical solutions from 715 kinds of solutions closing mode.By simulation analysis to achieve the rate of air output of each cooling tower,and obtained the required power equipment(i.e.,the power of fan).Through the analysis of the four typical scenario to discover the fourth discover is the better solution.Through the simulation analysis method can provide for similar engineering to select the best solution from the existing scheme.In this paper,numerical simulation of airflow organization airflow organization cooling tower has a great guiding significance to the practical engineering,and provide certain reference for relatively new practical engineering.
