Since the MCE occurs below room temperature these materials would not be suitable for refrigerators operating at room temperature. [13] Since then other alloys have also demonstrated the giant magnetocaloric effect. These include Gd 5 (Si x Ge 1−x) 4, La(Fe x Si 1−x) 13 H x and MnFeP 1−x As x alloys.
Food in a refrigerator with its door open. A refrigerator, commonly shortened to fridge, is a commercial and home appliance consisting of a thermally insulated compartment and a heat pump (mechanical, electronic or chemical) that transfers heat from its inside to its external environment so that its inside is cooled to a temperature below the room temperature.

The ionocaloric refrigeration cycle is an advanced cooling technology that utilizes the ionocaloric effect, driven by an electrochemical field, to achieve efficient and eco-friendly refrigeration. By manipulating the electrochemical potential through ion addition or removal, significant temperature changes and entropy variations are achieved.

The term "thermoelectric effect" encompasses three separately identified effects: the Seebeck effect (temperature ... room temperature, ... a refrigerator that is ...
The effect is purely an effect due to deviation from ideality, as any ideal gas has no JT effect. At room temperature, all gases except hydrogen, helium, and neon cool upon expansion by the Joule–Thomson process when being throttled through an orifice; these three gases rise in temperature when forced through a porous plug at room temperature ...
Most modern refrigerators keep the temperature between –40 and –20 °C, and have a maximum payload of around 24,000 kg gross weight (in Europe). Although commercial refrigeration quickly progressed, it had limitations that prevented it from moving into the household.
“The safest way to do this is in the fridge (never do it at room temperature) or using the microwave’s defrost setting. Once food has been defrosted, eat it within 24 hours.”
