AI Technical Summary
Existing technologies suffer from poor accuracy when testing the energy efficiency of refrigeration equipment, especially with significant differences in airflow meter test results under different temperature conditions, leading to inaccurate energy efficiency detection.
A refrigeration equipment energy efficiency testing device is adopted, including a chamber, a heater, a temperature sensor and a PLC controller. The PLC controller adjusts the heat output of the heater to maintain the temperature inside the cavity within a set range. A turbulent fan is used to ensure uniform gas flow, and polyurethane insulation board and rock wool layer are used to reduce the thermal conductivity of the chamber, so as to achieve accurate energy efficiency calculation.
This improves the accuracy of energy efficiency testing for refrigeration equipment, reduces the impact of temperature changes on test results, and ensures the accuracy and consistency of energy efficiency calculations.
