How Water comes out from a Refrigerator?

Refrigerator is a very common and popular electrical appliance in every house today, which contains thermally insulated compartment with the combination of electrical and electronic components.

This refrigerator pushes out water, although there is no water inside it, which is because of  the atmospheric air that enters during opening and closing of refrigerator.

When a refrigerator is opened, fresh air enters inside and is condensed due to the lower temperature of refrigerator, thus collected outside.

If the refrigerator remain closed for a while, there won’t be any water coming out of it.

However, refrigerator has five basic components for functioning such as, fluid refrigerant, compressor, condenser coils, evaporator coils and an expansion device.

In the mechanism, compressor constricts fluid refrigerant and pushes hot gas to the outside coils of refrigerator, and due to kitchen atmosphere (cooler) gas becomes liquid.

Thus, liquid refrigerant absorbs heat inside the refrigerator and transformed into gas and reaches compressor finally.

The cycle repeats.

Before the invention of refrigerator, ice houses were used to store things which are placed near freshwater lakes.

In 1755, Scottish professor William Cullen designed the first refrigerating machine, which had no practical application at that time.

Later in 1805, an American Inventor Oliver Evans discovered Vapor-Compression refrigeration cycle for ice production using vacuum.
