摘要
根据北京地区的全年气象参数,选择实际的新风机组,研究盘管的“冷量-流量”特性,并由此选取合理的控制阀阀权度。结果表明,对于集中空调水系统中的新风机组,采用阀权度Pv=0.3可以满足调节精度的要求,与常用的Pv=0.5相比,减小了水泵设计扬程,降低了输送能耗。
According to the annual climatic parameters in Beijing, selects an actual fresh air handling unit and studies the characteristics of cooling capacity with water flow rate for coils. Obtains a rational valve authority. As a result, a valve authority of 0.3 is satisfactory and is more economical in design pump head and transporting energy consumption compared with that of 0.5.
