Hot /Cold Water Dispenser Parts and Functions
Because of the popularity of water from refilling stations which comes in plastic gallons the hot/cold water dispenser has become an indispensable appliance in the home today.
Let us know the important parts of the water dispenser and the function of each..
A stainless tank with an evaporator coil wound around its side for cooling the water. The evaporator coils are similar to the that used inside refrigerator freezers.
A stainless enclosed tank with internal heaters for heating the water inside the tank and insulated with foam to conserve heat.
The heater tank includes an internal heater drawing at least 2 amperes of current to bring the water temperature up to boiling point.
The water is channelled from the tanks to the dispenser faucets via silicone tubings. The silicone tubings are soft and flexible and resistant to hot and cold temperatures.
The heating tank thermostat's cutoff termperature is rated below near the boiling point of water which is 100 deg. centigrade. The thermostat will become open circuited when water inside the heating tank starts to boil. It is to prevent overheating which can damage the heating tank.
