摘要
详细介绍了单元式空调机标准GB/T 17758-2010空气焓差法测量制冷量的数学模型及计算公式,编制了相应的计算软件。同时对额定制冷量为10k W单元式空调机的试验数据进行了分析计算,并对测量结果的不确定度进行了评定。提出了减小制冷量测量不确定度的途径,用以提高实验室测量数据的准确性和可信度。
The mathematical model and calculation formula of the air enthalpy difference method for the unitary air conditioners′standard GB/T 17758-2010 were introduced in detail,and the calculation software was programmed.At the same time,The experi-mental data and uncertainty of the measurement results for unitary air conditioners were analyzed,whose rated refrigerating capaci-ty is 10kW.In order to improve the accuracy and reliability of the data measured in the laboratory,the way of reducing the cooling capacity was put forward.
