High output water cooled thermoelectric refrigerator

Abstract

Thermoelectric cooling had been an alternative cooling method to vapor compression system. This is due to the lack of harmful refrigerant, packaging, as well as the low noise operation. Currently, there are application of a thermoelectric refrigerator. Most of the existing products are usually made in small size and lack the ability to quickly cool down the space or withstand external heat source such as having hot items being placed within the refrigerator. This research was an experiment regarding to the application of high output thermoelectric refrigerator. It involved a 720 watt water to air thermoelectric module placed through a 40 liter insulated cabin and temperature data are collected to determine the possibility of overcoming the demerits of thermoelectric refrigerators. The water flow rate had been regulated at 400, 500 and at the system’s maximum limit of 600 liters per hour.  The results were the system reached below the freezing temperature within 30 minutes under no load condition. Therefore the feasibility of high output thermoelectric cooler application is a compact and possible approach towards initiating a cooling scheme in closed area within a short time.
