Air Conditioning Systems

The environmental degradation becomes a great matter of concern due to use and disposal of Chloro-Fluoro-Carbons (CFCs) and Hydro Chloro-Fluoro-Carbons (HCFCs) as refrigerants in conventional refrigeration and air conditioning systems. This leads to extensive research into development of alternate refrigeration systems. Solar energy which is renewable source of energy is available abundantly in the environment. This study deals with the design and development of eco-friendly solar powered thermoelectric refrigeration system. In rural areas where people have to deal with electricity problems, this thermoelectric module will be very helpful to them as it runs on solar energy. Vegetables, Food items and other different required things can be preserved in it. In thermoelectric refrigeration system, the mechanical parts and coolants which are used in conventional refrigeration systems get eliminated and a thermoelectric module is used instead which is cost effective and vibration free. The objective of this study is to develop a working thermoelectric refrigeration system to cool a volume of 5 lit capacity cabinet that utilizes the Peltier effect to cool and maintain a selected temperature range of 8<sup>0</sup>C to 15 <sup>0</sup>C. Solar panel is used to provide the required energy to run this system.

New Type

The thermoelectric refrigeration system is an application of the Peltier effect, and good refrigeration performance is dependent on effective heat dissipation performance. To enhance the cooling performance of the thermoelectric system, this paper designs a new type of finned heat sink, which does not change the overall size of the thermoelectric system. The performance of the refrigeration system under the new fin is tested by experiments under various conditions. During the experiment, the cooling wind speed, the temperature of the hot and cold side of the TEC, the power consumption of the fan, and other parameters were directly recorded through the measuring instrument. The results show that the use of new finned heat sinks can improve the COP of the thermoelectric refrigeration system. Within the scope of the study, the thermal resistance of the new fins can be reduced by , and the system COP value can be increased by . In addition, increasing the cooling wind speed can further reduce the cold side temperature. Within the research range, the lowest temperature can reach , but the power consumed by the fan is of that of the conventional fin heat sink refrigeration device.
