摘要(Abstract):

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 experimental data and uncertainty of the measurement results for unitary air conditioners were analyzed,whose rated refrigerating capacity is 10 k W. 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.
