Test uncertainty of integrated part load value (IPLV)
Based on the uncertainty theory of indirect measurement quantity,the un-certainty calculation model of integrated part load value (IPLV)of air-conditioning prod-ucts is established.The uncertainty of IPLV measurement is analyzed based on a low am-bient temperature air source heat pump (water chilling)packages.The results show that Type B standard uncertainty from power measurement has a greater influence on IPLV,followed by inlet and outlet water temperature measurement and water flow measure-ment.The influence of the Type A standard uncertainty of IPLV on the combined standard uncertainty can be neglected.In the IPLV measurement of air-conditioning prod-ucts,it should pay more attention on the accuracy of instrumentation,as higher accuracy of instrumentation can effectively reduce the measurement uncertainty of IPLV of air-con-ditioning products.
