Termoelektrik peltier'in ısıtma ve soğutma performansının karşılaştırılması için deneysel çalışma

Abstract

On a globalscale it is considered that, a notable part of the overall electrical energy is consumed in refrigeration and air conditioningsectors. Refrigeration sector is also known as an important and critical industry in the field of food and pharmacy sectors. In generalrefrigeration and also freezing applications are based on the extracting thermal energy from the freezing or cooling medium to keepthe 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 comparativeinvestigations focused on thermoelectric devices and their efficiency with well-known vapor compression refrigeration systems areless regarded in the literature.In this study, Peltier thermoelectric performance was obtained in two different ways and the results were compared. First, the COPvalue was obtained when cooling was carried out in an insulated box and then in different mode, the heating of the box was carriedout. It was observed a big difference between COP values of heating and cooling modes. According to the achieved experimentalresults of this study, the COP or coefficient of performance value in the heating mode is approximately 200% greater than that ofcooling mode.
