The magnetocaloric effect is the basis of this technology, where paramagnetic materials show reversible temperature change if exposed to a changing magnetic field. magnetocaloric technology can be used for heat pumps as well as air conditioning applications. Magnetocaloric technology is reported to have the potential to reduce energy consumption of 20% when compared to mechanical vapour compression (Magnetic, 2016; SAE, 2013). 12.3.1.2 Thermoelectric: Development Status: Widely Commercially available Thermoelectric cooling technology is currently less efficient than mechanical vapour compression. However, thermoelectric systems are simple and have an economic advantage over vapour compression systems for capacities requiring less than 50 W cooling. It is expected nanomaterials research may deliver better thermoelectric materials in the future and provide system efficiencies comparable to vapour compression systems. The technology is commercialised in rather small applications and also in low efficiency systems. Those are available for cars for temperature conditioning of seats, especially for High Ambient Temperature conditions when cars are parked for extended periods while exposed to direct sunlight. Spot cooling for electronics equipment, portable refrigerators, wine cabinets -to improve the efficiency of vapour compression systems sub-coolers- are some of the applications of thermoelectric technology. Small water coolers, compact refrigerators and portable coolers are also applications that are commercially available. 12.3.1.3 Thermotunneling: Development status: R&D 238 2018 TOC Refrigeration, A/C and Heat Pumps Assessment ReportPDF Image | Heat Pumps Technical Options
