What is carbon monoxide and how is it produced?
Carbon monoxide (CO) is a colorless, odorless gas that can be harmful or even fatal when inhaled in large amounts. It is produced during the incomplete combustion of fossil fuels, such as gas, oil, and wood, commonly found in vehicles, heaters, and gas appliances. CO can accumulate in poorly ventilated spaces, posing serious health risks to individuals exposed to it.
While carbon monoxide can originate from various sources, including some home appliances, it is essential to understand that most household refrigerators do not produce CO. Instead, they operate using refrigerants and electrical components that do not involve combustion processes, minimizing any risk connected with CO emissions.
Do refrigerators use combustion to operate?
No, refrigerators do not use combustion as part of their operating process. Refrigerators utilize electric compressors and refrigerants to cool the interior of the appliance.
