explain the mechanism of water cooler
Answers
Answer;
Inside the water cooler is a valve that prevents the water from the bottle flooding the water cooler. The water inside the water cooler is fed into a reservoir, where it is cooled using a refrigerant. A refrigerant is a cooling medium that is circulated in pipes that are located close to the reservoir in the water cooler. The refrigerant changes from a liquid to a gas as it moves in the pipes towards the reservoir because of the pressure in the pipes created by a compressor inside the water cooler. The cooled gas in the water pipe is forced through a valve to make it even colder.
When the refrigerant is in a gas form and is circulating in the pipes, it has the ability to absorb the heat away from the mineral water in the reservoir, leaving cool and refreshing water that is readily available. The heat in the refrigerant is then expelled from the water cooler.
As people dispense water, the machine will refill the reservoir and the process begins again. Should the water reservoir empty completely during dispensing, it will take a few minutes before the water cooler chills the water to a low temperature.
