Abstract
Objective. The aim of the work is to develop a calorimetric stand that allows simulating the operation of an energy-efficient two-evaporator refrigeration unit of a household refrigerator or freezer.
Method. In the course of the work, a calorimetric setup is described that allows conducting experimental studies to determine the cooling capacity and energy efficiency of a modernized refrigeration unit of a household refrigerator.
Result. Currently, new resource-saving circuit solutions for household refrigeration equipment have been developed. The developed solutions make it possible to increase the efficiency of the refrigeration unit, as well as to reduce its energy consumption. Theoretical calculations confirming these indicators have been carried out. To confirm the calculated values, automated experimental studies are required to determine the parameters of the refrigeration unit. The paper proposes a description of an automated calorimetric stand that allows simulating the operation of an energy-efficient dual-evaporator refrigeration unit of a household refrigerator or freezer.
Conclusion. The designed calorimetric stand will allow carrying out complex experimental studies to determine the cooling capacity of the modernized refrigeration unit when operating on various refrigerants. The experimental setup also makes it possible to measure the temperature and pressure during the operation of the refrigeration unit, as well as to determine the influence of various factors on its characteristics.
