Study of characteristics of thermoelectric refrigerator laboratory model

A laboratory model of a thermoelectric refrigerator was studied on an experimental stand, providing a wide range of temperature conditions and power supply parameters. The stand is equipped with a set of equipment for measuring electrophysical parameters and temperature. Temperature measurements were taken to determine the thermal resistance of the refrigerator model body and heat supply and removal devices. The load characteristics of the thermoelectric module were measured at different values of current and temperature of its hot side. The dependences of the cooling capacity of the thermoelectric module on the current were obtained at different values of the coolant temperature. In addition, a laboratory model of a thermoelectric refrigerator was tested in maximum cooling mode
