高压换流站空调系统变工况冷却特性研究

Study on Cooling Characteristics of HV Converter Station Air Conditioning System under Different Working Conditions

准确掌握高压换流站空调系统在变工况条件下的冷却特性,可以实现低能耗的室温高效冷却。为此,研究高压换流站空调系统变工况冷却特性。将空调系统划分为压缩机、冷凝器和节流阀三大部分,设定温湿度、风速等测点位置。在实验中,设定变工况下的实验条件,通过设计模型分别得到不同条件改变下对空调系统冷却的影响。实验结果表明,在另外两种条件固定的情况下,室外温度对空调冷却的影响可以忽略不计,换流站空气含水量越高,空调冷却效果越好,而处理空气送风量越大,空调冷却效果就会相应降低。

Accurately mastering the cooling characteristics of the air conditioning system of the high-voltage converter station under vari-able working conditions can realize low-energy and efficient room temperature cooling.Therefore,this paper studies this.The air conditioning system is divided into three parts:compressor,condenser and throttle valve,and the measuring points such as tem-perature,humidity and wind speed are set.In the experiment,the experimental conditions under variable working conditions are set,and the effects of different conditions on the cooling of the air conditioning system are obtained through the design model.The experimental results show that when the other two conditions are fixed,the influence of outdoor temperature on air condition-ing cooling can be ignored.The higher the air moisture content in the converter station,the better the cooling effect of air condi-tioning,and the larger the air supply volume of treated air,the cooling effect of air conditioning is reduced accordingly.
