IEC 62552-3:2015 PDF Download

A standard called IEC 62552-3:2015 is dedicated to home refrigeration equipment. It lists the key traits that make these appliances unique and offers test procedures to measure them. The standard mainly focuses on volume measurements and energy consumption.

The standard's enhanced testing criteria, which take into consideration new product configurations, electronic controls, and data collection techniques, are one of its most important features. To more thoroughly assess the performance of the device under various circumstances, the energy consumption tests have been broken down into numerous components, such as steady-state operation, defrost, and recovery.

The standard offers a way to measure each energy component and specifies various methods for estimating energy consumption under various usage and environmental circumstances. By permitting the selection of components and weightings that are most appropriate for regional performance and energy efficiency standards, it is made to be flexible to local requirements.

Part 3 of the standard contains detailed instructions for measuring energy use, including the use of average air temperature sensors and the lack of thermal mass in any compartment. For the energy consumption testing, two ambient temperatures—16°C and 32°C—are also specified.

Part 3 provides a load-processing energy efficiency test for home refrigeration units in addition to energy consumption data. In addition to performance and energy tests for regular domestic refrigeration appliances, the standard also includes tests for wine storage units.
