发布时间：2018-08-13 14:57
【摘要】：冷水机组的IPLV是通过测试基于规定工况下的部分负荷性能系数值计算得来的。随着技术的进步,目前由多台机组构成的大容量模块式冷水机组越来越多,其整机的IPLV值与各模块单元的容量以及各模块的运行控制逻辑密切相关。本文对比测试了由两台相同容量单元组成一台大容量模块机组在不同控制策略时的IPLV值,发现控制策略对IPLV值的影响显著。对于由2台额定制冷量为100 k W机组构成的200 k W模块式冷水机组而言,采用不同的控制策略进行测试时,水冷式冷水机组的最小IPLV值为5.32、最大IPLV值为6.73;风冷式冷水机组的最小IPLV值为3.39、最大IPLV值为3.83,蒸发冷却式冷水机组的最小IPLV值为4.49、最大IPLV值为5.39。上述测试数据为产品控制策略的研发提出了有益的参考。
[Abstract]:The IPLV of the chiller is calculated by testing the partial load performance coefficient under specified working conditions. With the development of technology, there are more and more large capacity modular chillers composed of many units. The IPLV of the whole unit is closely related to the capacity of each module unit and the operation control logic of each module. In this paper, the IPLV values of a large-capacity modular unit composed of two units with the same capacity are tested and compared with each other. It is found that the control strategy has a significant effect on the IPLV value. For 200kW modular chillers composed of two units with rated refrigerating capacity of 100kW, when different control strategies are adopted, The minimum IPLV value of water-cooled chiller is 5.32, the maximum IPLV value is 6.73, the minimum IPLV value of air-cooled chillers is 3.39, the maximum IPLV value is 3.83, the minimum IPLV value of evaporative cooling chillers is 4.49 and the maximum IPLV value is 5.39. The above test data provide a useful reference for the R & D of product control strategy.
