Drinking Water Cooler

A water dispenser, known as water cooler (if used for cooling only), is a machine that dispenses and often also cools or heats up water with a refrigeration unit. It is commonly located near the restroom due to closer access to plumbing.A water cooler works by using a refrigerant to cool water. The refrigerant is compressed, causing it to become hot. The hot refrigerant is then passed through a condenser, which cools it down.
