Abstract

On a global scale it is considered that, a notable part of the overall electrical energy is consumed in refrigeration and air conditioning sectors. Refrigeration sector is also known as an important and critical industry in the field of food and pharmacy sectors. In general refrigeration and also freezing applications are based on the extracting thermal energy from the freezing or cooling medium to keep the temperature at the specified standard levels suitable for storage foods or medicines.
Vapor compression refrigeration systems are mostly employed for cooling, heating and air conditioning purposes, but comparative investigations focused on thermoelectric devices and their efficiency with well-known vapor compression refrigeration systems are less regarded in the literature.
In this study, Peltier thermoelectric performance was obtained in two different ways and the results were compared. First, the COP value was obtained when cooling was carried out in an insulated box and then in different mode, the heating of the box was carried out. It was observed a big difference between COP values of heating and cooling modes. According to the achieved experimental results of this study, the COP or coefficient of performance value in the heating mode is approximately 200% greater than that of cooling mode.
