Cooling storage devices are most important to store food items, medicines., etc. for long-term applications, we designed these devices. Nowadays to store food items and medicines are in refrigerators due to this refrigerator, and the environment will be affected by harmful gases like Hydrofluorocarbons (HFCs) and chlorofluorocarbons (CFCs) released by refrigerators. This is harmful to the human breathing system to avoid this defect, we are going to design this device with help of a thermoelectric couple (Peltier module), The thermoelectric module consists of semiconductor-based materials that are thermally and electrically coupled in parallel and series, respectively, to produce hot and cold temperatures on each side of the module. with help of this module to design the cooling device, due to this device, we protect the environment from the harmful gases released by the refrigerator. Human breathing system is affected by these harmful gases to avoid this defect here I am using a thermoelectric couple, because this module is not releasing any type of harmful gases and also do not disturb the human breathing system so that's why only, here I was taken the Peltier module.
