Evaluation of a Different Model of Affordable Eco Cooler Using Thermoelectric Module and Joule Thomson Effect and Its Social Aspects

Researchers have lately shown an interest in developing piezoelectric technology as a particularly noble cooling method definitely due to its obvious benefits over compression refrigeration methods like the absence of a compressor, refrigerator, moving parts, and other components. However, very few models of these types of air coolers kind of have been tested so far. This research particularly focuses on a unique thermoelectric air cooler model, including the Joule Thomson effect of air. The objective of this research is to provide an affordable cooling solution for the lower-income people living in slums and mountainous regions where the supply of enough electricity is a big issue. To produce the Joule Thomson effect, a cone-shaped physical model constructed of Polylactic acid was 3D printed, and six Peltier modules were positioned radially to strain the Thermoelectric effect and a forced draft fan is used to supply the required air with very high velocity and pressure. This product will not only be cost-efficient but also will be environmentally friendly. The social acceptance of this kind of cooler mostly has been quite a large issue also. Thus, a survey has been conducted on 50 middle-class to really poor people of Mirpur 11 (Parise Road slums) and Vashantek where the importance of this kind of cooler has particularly become. Around 76% of them found it useful and generally were very kind of interested in it being set in their houses, which is quite significant. However, a presence of doubt in the mind of basically many people about the lifespan of this product sustains.
