- Abstract
- Thermoelectric module (TEM), non-vapor-compression heat pumps, are of interest as substitutes for conventional vapor-compression heat pumps. However, the heat exchange effectiveness and performance of TEMs for application to heating, ventilation, and air conditioning (HVAC) systems had been less studied. The purpose of this research is to propose the system configuration of TEM heat pump unit and to predict the heat exchange effectiveness in air heat pump system using TEM. The proposed system is composed by flat plate fin array that is heat exchanger integrated TEM for cooling and heating. The experiments were conducted to predicting the cooling and heating heat exchange effectiveness by collecting performance data. The performance data are composed by the inlet air fluid temperature, air flow rates at each side, heat exchange area, and input direct current (DC) to the TEM. Outlet fluid temperatures and TEM surface temperature are also measured for deriving the heat exchange effectiveness. Design parameters had significant impact on the heat exchange effectiveness of the flat plate heat exchanger integrated TEM for air cooling and heating. Consequently, in this paper, the influence of the five input parameters (air temperature at both side, air flow rate at both side, current) were analyzed. In proposed unit, the heat exchange effectiveness of hot and cold sides was 0.41 to 0.59 and 0.23 to 0.30, respectively
