摘要(Abstract)：

基于液体载冷剂法,分析了水冷式冷水机组进出水温度和水流量允差在GB/T 18430.1-2007范围内变动对机组性能测试结果的影响,研究发现:冷媒水出水温度正偏差和冷却水进水温度负偏差均会强化机组的制冷量,冷媒水出水温度负偏差和冷却水进水温度正偏差均会弱化机组的制冷量。基于GB/T 18430.1-2007的允差条件,可能会导致对水冷式冷水机组制冷量的不合理判定。研究成果能够为准确测定水冷式冷水机组的性能、冷水机组国家标准和能效标准的修订提供指导,同时也为设计高精度的试验台提供理论依据。
Based on the liquid secondary refrigerant method, analyzes influence of the allowable deviation of entering and leaving water temperatures and water flow on performance of the water chillers. The study found that positive deviation of leaving temperature of the refrigerant water and negative deviation of entering temperature of the cooling water will strength cooling capacity of the unit,negative deviation of leaving temperature of the refrigerant water and positive deviation of entering temperature of the cooling water will weaken cooling capacity of the unit. It may lead to unreasonable determination of the unit cooling capacity according to the allowable deviation of GB/T 18430.1-2007. The research results can provide reference for accurate measurement of the unit cooling capacity and revision of the national standard and energy efficiency standard,but also provide theoretical basis for the design of high-precision test bench.
