Thermoelectric cooling technology presents evident advantage in solving the climate crisis problemsand beneficial over conventional cooling systems for space conditioning applications. Due to its low energy efficiency, thermoelectric cooler (TEC) consumes more poweras compared to a conventional cooler does with the same cooling capacity. A test experimental set up has been developed to improve the energy efficiency i.e., coefficient of performance (COP)of TEC and work reliability, by introducing suitable PCM with transient temperature and large storage capacity to the cold and hot side sinks for thermal controls with air-forced convection. The optimal thermoelectric cooling performance and desirable input supply of TEC module was experimentally tested and the temperatures at thermal sides of TEC was controlled and maintained below the working ranges. The results of tests conducted show that, attaching PCM to the cold side of TEC improved the COP by 8.57% for the test set up. Further, it also gives the cooling storage capacity, which would be particularly useful in case of power failure. The use of PCM at the hot side of the TEC keeps the temperature at the hot side below the maximum working temperature range of 40-43℃ for much longer time, thereby improving the COP of TEC from 0.58 to 0.685 with percentage improvement of 18.1%. Thus, it demonstrated that the use of PCM could regulate thermal temperatures, improving TEC’s performance and work reliability.
