Abstract: This paper is based on the analysis of calibration methods and results of environmental temperature field in the performance testing chamber of household and similar refrigerating appliances. The performance testing chamber of household refrigerating appliances (hereinafter referred to as " testing chamber ") can simulate different climate types, and is an important device for testing and researching household and similar refrigerating appliances. The testing chamber is composed of computer control system, measuring instruments, sensors and data acquisition devices. It is mainly used to test the temperature, power consumption and energy efficiency of refrigerating appliances.This paper describes in detail the calibration method of the environmental temperature field in the testing chamber and the calculation process of the calibration results. It is hoped that it will be helpful to the experimenters and better serve the enterprises and testing laboratories to ensure the accuracy and consistency of the performance testing of refrigerating appliances.

Key words: Refrigerating appliances, Testing chamber, Environmental temperature field, Calibration
