【摘要】：冷水機組的IPLV是通過測試基于規(guī)定工況下的部分負荷性能系數(shù)值計算得來的。隨著技術的進步,目前由多臺機組構成的大容量模塊式冷水機組越來越多,其整機的IPLV值與各模塊單元的容量以及各模塊的運行控制邏輯密切相關。本文對比測試了由兩臺相同容量單元組成一臺大容量模塊機組在不同控制策略時的IPLV值,發(fā)現(xiàn)控制策略對IPLV值的影響顯著。對于由2臺額定制冷量為100 k W機組構成的200 k W模塊式冷水機組而言,采用不同的控制策略進行測試時,水冷式冷水機組的最小IPLV值為5.32、最大IPLV值為6.73;風冷式冷水機組的最小IPLV值為3.39、最大IPLV值為3.83,蒸發(fā)冷卻式冷水機組的最小IPLV值為4.49、最大IPLV值為5.39。上述測試數(shù)據(jù)為產(chǎn)品控制策略的研發(fā)提出了有益的參考。
[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.
