Investigation of the Simultaneous Cooling and Heating Using a Thermoelectric Peltier †

Abstract

Substitution of vapor compression refrigeration systems (VCRS) by using Thermoelectric Peltier offers numerous advantages. The Peltier effect is the inverse of the Seebeck effect: as a current flows between two dissimilar materials, it causes one side to grow hotter, making the other side cooler. This effect was experimentally exploited to simultaneously cool and heat water. In 60 min, 1 L of water was cooled from 40 °C to 16 °C and another liter heated from 25 °C to 45 °C. Power consumption was about 0.0828 kWh with a COP of 1.33, which can be enhanced using improved methods of heat dissipation on the Peltier device.
