Abstract

Abstract: The actual state of the commercial circulating heat pump hot water heater during the initial startup to heating process has a certain impact on the performance index of the hot water heater. However, the performance standard GB/T 21362-2008 "heat pump hot water heater for commercial or industrial use and similar purposes" does not clearly specify the requirements of the product startup test state. There are certain differences in the methods used by different institutions in the test and research process, and how this difference affects the product performance evaluation. In this paper, different initial heating temperatures are selected through the experimental method to make the commercial circulating heat pump hot water heater work under different initial conditions, and then study the trend of its influence on the performance of commercial circulating heat pump hot water heater, and discuss the possible applications for testing.

Key words: Heat pump water heaters, Initial heating temperatures, Testing
