本文以房间空调器为例,简要介绍房间空调器性能测试方法(空气焓值法)的测试原理,分析在这种测试方法中几个重要参数(风量、制冷量、制冷消耗功率)的影响因素,然后着重阐述空气焓值法的测量不确定度评定的详细过程,分析测量不确定度评定过程中各个参数对测量不确定度的误差影响。
This paper takes the room air conditioner as an example, briefly introduces the test principle of the air conditioner performance test method (air enthalpy method), analyzes the influencing factors of several important parameters (air volume, cooling capacity, cooling power consumption) in this test method Then, the detailed process of evaluating the measurement uncertainty of the air enthalpy method is emphatically expounded, and the influence of each parameter on the measurement uncertainty is analyzed when the measurement uncertainty is assessed.
