Thermal performance test analysis on air source heat pump water heater for household and similar application
In order to better understand the terms in GB/T 23137-2020 Heat pump water heater for household and similar application,and conduct the test on thermal per-formance of air source heat pump water heater accurately,the performance test and calcu-lation methods of air source heat pump water heater are interpreted.Firstly,to ensure the accuracy of performance test of air source heat pump water heater,it is suggested that the omissions of the formula should be corrected,and the definition and unit of the same physical quantity should be unified in the standard.At the same time,the influence of atmospheric pressure on the test results is considered.Secondly,relevant parameters of thermal performance of air source heat pump water heater is analyzed,it is pointed out that the performance index obtained by single occurrence time has limitations in the evalu-ation of water heater.Finally,it is pointed out that the energy efficiency standard or prod-uct standard of air source heat pump water heater should be updated in time to keep the evaluation mechanism consistent.
