THE COOLING PERFORMANCE OF THE EVAPORATIVE COOLING SYSTEM (COOLING PAD) IN COMBINATION WITH THERMOELECTRIC DEVICES
The purpose of this paper is to produce an air cooling system which is environmental friendly. This paper represents the investigation of the application of an evaporative cooling system with thermoelectric devices (TEC’s). This combination system is designed to produce comfort air for an indoor climate. The evaporative cooling system can be created by water spray on top of a cooling pad. Heat is transferred between water and air, causing air outlet temperature to decrease (relative humidity, %RH increase). When the air passes through the TEC’s its temperature further decreases (%RH decrease). The variable values are air inlet temperature, water flow rate, and TEC current. In the first stage, the water spray attempt to sets the proper air temperature and humidity to the room’s standard. However, TEC’s play an important role during the experiment to control the comfort conditions. The experimental work also showed that the TEC’s limited cooling capacity needed to be improved by increasing its input current. The advantages of this system are that it is compact, possesses no moving parts, and is environmentally friendly.
