“…Considerable amount of research has been conducted in the field of thermoelectric cooling to predict and optimize the performance of thermoelectric modules 3–11. Huang et al reported that the two major factors for enhancing the efficiency of the thermoelectric modules are the heat sink thermal resistance and the appropriate cooling capacity to reach optimal performance 3.…”

SUMMARY The main objective of this study is to present an integrated thermoelectric–photovoltaic renewable system to dehumidify air and produce fresh water. The system is combined with a solar distiller humidifying ambient air to enhance distillate output to meet the specified fresh water needs for a residential application. A model is developed to simulate the air dehumidification process using thermoelectrically cooled TEC channels. Experiments were performed to validate the developed model results. It is found that the model predicted well the variation in the air temperature along the channel with a maximum relative error in air temperature less than 2.4%. In addition, the simulation model predicted well the amount of water condensate produced by the integrated system with a maximum relative error of 8.3%. An optimization problem is formulated to design and set the integrated system optimal operation to produce 10 L of fresh water per day meeting the fresh water needs of a typical residential. Using five TEC channels of a length of 1.2 m and an area of 0.07 × .05 m2 integrated with 1.2‐m2 solar distiller that recirculates a constant air mass flow rate of 0.15 kg s−1 is capable of meeting water demand when air mass flow rate through each TEC channel is optimally set at 0.0155 kg s−1. The associated optimal electrical current input to the TEC modules varied depending on the month and is set at 2.2 A in June, 2.1 A in July and 2.0 A in August, September and October.

a b s t r a c tThe main objective of this study is to design and build an affordable solar thermoelectric refrigerator for the Bedouin people (e.g. deserts) living in remote parts of Oman where electricity is still not available. The refrigerator could be used to store perishable items and facilitate the transportation of medications as well as biological material that must be stored at low temperatures to maintain effectiveness. The design of the solar-powered refrigerator is based on the principles of a thermoelectric module (i.e., Peltier effect) to create a hot side and a cold side. The cold side of the thermoelectric module is utilized for refrigeration purposes; provide cooling to the refrigerator space. On the other hand, the heat from the hot side of the module is rejected to ambient surroundings by using heat sinks and fans. The designed solar thermoelectric refrigerator was experimentally tested for the cooling purpose. The results indicated that the temperature of the refrigeration was reduced from 27 C to 5 C in approximately 44 min. The coefficient of performance of the refrigerator (COP R ) was calculated and found to be about 0.16.

“…In their study, Sterling and vapour compression refrigeration system have an overall thermodynamic efficiencies ranging between (14-15)%, whereas the thermoelectric system have about 5%. Bansal & Martin (2000) [16] carried out investigative study on performance analysis of conventional and non-conventional refrigeration system including vapour compression system, vapour absorption system and thermoelectric system. Their study revealed that the vapour compression refrigeration had highest COP around (2.59), thermoelectric system had (0.69) and absorption refrigeration system had (0.47).…”

This paper comprises the Numerical study of various modules of first and second stage of peltier cooler to analyze that how the performance enhances when we shift from single stage to cascade thermoelectric peltier cooler. Multistage thermoelectric coolers have been used from long back as they offer a larger temperature difference than single-stage thermoelectric coolers. Apart from this multistage also helps in improving the COP and cooling load. The COP and heat load were analyzed for various temperature difference and it has been observed that they decrease with increase in temperature difference . For first stage COP ranges from 0.1 to 0.34 and cooling load maximum as 41.9 whereas for second stage COP maximizes to 0.56 and cooling load to 136.45.
