We have previously talked about thermoelectricity in this blog. As you may know, there are three thermoelectric effects: Peltier, Seebeck and Thomson. Humbly, we could say that we have some experience in the use of Peltier effect. Thanks to that experience, we have published an article about a thermoelectric cooling heating unit prototype that we have monitorized for more than one year.
Thermoelectric unit based on Peltier
Peltier cells are really interesting. We can usually find it in aerospace installations or as a heat sink. One of the most common places to put Peltier cells is your car seat. If you have heated seats, Peltier is probably the solution used to do it. Among the advantages that Peltier cells have in comparison with other systems, we can remark the following ones:
- Low or hardly non existing maintenance.
- Possibility to generate and dissipate heat with the same unit.
- Absolutely noiseless. No vibrations.
- Better performance than electrical resistances.
As can be read in the abstract of the article published, the solution proposed is an inventive prefabricated system. It can be used to provide heating and cooling (extracting heat) and have been monitorized for more than one year in the School of Architecture of the University of Navarra. As mentioned in the article, the practical applications of this prototype could be the following ones:
The system opens new ways to the air-conditioning without using the traditional concepts of primary and secondary loop, because the system is highly independent. Their applications could be in building refurbishment where other systems involving the use of water or air are complicated to implement, in spaces where security and resilience are crucial factors (such as surgeries or computer server rooms), or those situations with extreme maximum and minimum temperatures or irregular electrical supply, as those could exist when the army must intervene or an humanitarian disaster occurs.
The article has been published in the Building Services Engineering Research & Technology journal. We really encourage to take a look at the whole article if you have access to it. Also, keep up reading this blog, as the second version of the prototype is already built and we will publish some news soon.
