SO MOST OF US PROBABLY HAVE WATER DISPENSERS IN OUR HOMES BUT HOW MANY OF US REALLY KNOWS HOW THEY FUNCTION, THIS IS INFORMATIVE AND INTERESTING, ENJOY!

i was given this project to work on in my school so i thought i should actually share it here
HOW DOES A HOT AND COLD WATER DISPENSER WORK?
Have you ever wondered how a hot and cold water dispenser works? Normally when you are getting yourself a glass of water, you simply press the relevant tap and tada! Water appears in your cup. The process which takes place within the water cooler is simple yet very interesting. Take a look at how a plumbed in water cooler works below:

This plumbed in water dispenser diagram dispenses both hot and cold water. The hot water is heated at around 95 degrees Celsius after passing through two carbon filters. As it is heated it does not need any further filtration and will exit out of the tap.
Cold water goes through a slightly longer process to make sure it is free from bacteria and other unwanted chemicals. The cold water runs through two carbon activated filters, followed by a UV light chamber where it is purified. CO2 is added to the water if there is a sparkling water option on your water dispenser. It then dispenses the relevant option of cold or sparkling water.

A water dispenser is, as its name implies, a devise that dispenses water.
It is used to provide easy access to drinking water. Water dispensers have become a necessary part of society.
• Some water dispensers provide clean, filtered water from a replaceable bottle.
• Other water dispensers provide water straight from a municipal water line.
• Some dispensers perform functions like filtering water, heating water, or cooling water
A water dispenser can be useful in many situations. Some offices prefer to have a water dispenser because it provides clients and employees with convenient access to water, without having to take extended breaks or drive to the store.
• Water dispensers are also commonly used in residential homes that do not have ideal drinking water from the tap, or for people who simply do not like the taste of the tap water.
• Water dispensers are typically an environmentally friendly option, as personal bottled water leaves a lot of plastic waste.
Whether psychologically, or for real reasoning, people tend to enjoy water from a dispenser over water from a sink. Because many water dispensers provide the option to have water immediately cooled or heated, its convenience has become a necessity in many businesses and residential homes.
In addition, many water dispensers have the option to use filtered water, which many people enjoy more than hard water from a tap.
How Does a Water Dispenser Work?
Most water dispensers typically use the same simple concept: deliver water from a source through a tap or spigot, usually using a button or knob for users to dispense the water.
However simple the concept, how a dispenser works depends on the type of dispenser. There are different types of water dispensers:
Mounted Water Dispensers: Mounted Water Dispensers are commonly referred to as water fountains. They are found in public places such as theme parks or boardwalks, in parks, or in large office buildings.
• The dispenser mounts to a wall, or can be freestanding on the ground, and taps water from an existing water line.
• The water is dispensed by the user by turning a knob or pressing a button, which sends a stream of water until the knob or button is released. The water is sent in an arched formation to make drinking easy.
• Typically a water fountain is not used to fill cups, but rather to take a quick drink from the receptacle.
• Mounted water dispensers are usually tapped into the municipal water supply which means the water is not usually cooled, heated, treated or filtered. So on cold days, the water is cold and on warm days the water is warm.
• However, some water fountains, like that in large cooperation's, office buildings, or in places that have electricity available, do have water coolers inside to cool the drinking water prior to dispensing it.
Mounted water dispensers are usually the most primitive of water dispensers, as they usually don't have any special functions like heating, cooling, or filtering water. For this reason, mounted dispensers don't usually have many parts. The parts on a mounted filter are usually:
• A tank- to draw water into from the main line
• A spigot- that sends a stream of water into the air in an arched form to make drinking easier.
• A button or knob- that when pressed releases the water
• A cooler or refrigerated system- if the water fountain is designed to cool water
Point of Use Water Dispenser: Point of use water dispensers are similar to a mounted water dispenser, as they are used by tapping into an existing water line.
• Point of use water dispensers are typically found in businesses and residential homes that require convenient access to water.
• Point of use water dispensers are a convenient option because they have an unlimited supply of wateravailable, since it's connected to a water line.
• Point of use water dispensers do not require replacing bottles periodically in order to ensure water is available through the dispenser.
• Point of use water dispensers usually have the ability to cool and heat water by storing water in a tank and using electricity to warm or heat the water prior to dispensing it.
• Point of use water dispensers usually filter the water coming from the water line.
• A point of use water dispenser is connected to the main water line, it stores water in a tank, heats and cools it, if applicable, and is dispensed by users by turning a knob or pressing a button. Water is funneled through a tap located in the front of the dispenser.
Point of use water dispensers come with various uses, the best of them cool, heat, and filter water. Point of use water dispensers have more parts than a mounted water dispenser because they usually have more components.
• A tank (or two) - to store water to be chilled or heated prior to dispensing.
• A water heater- to warm water
• A refrigerating system- to cool water
• Water filters- to filter the tap water
• A tap or spigot- for users to receive water from
• A button or knob- to release water
• These types of filters typically require electricity to function
Bottled Dispensers: Bottled water dispensers are the commonly referred to water dispenser.
• Bottled dispensers are similar to point-of-use water dispensers as they are often available with options to cool and heat the water prior to dispensing it.
• Usually, a five gallon water bottle is placed upside down in the water dispenser's tank. This is an ideal option for those who do not wish to drink tap water, or for those who do not have the option to connect into the main water line.
• Usually the water in bottled water is high quality, filtered water.
• The bottled water dispenser works the same way as a point of use dispenser, as the user simply presses a button or turns a knob to release the water into the funnel.
• Bottled water dispensers may require more maintenance than point of use dispensers because, bottle service is usually necessary to ensure enough water is available. The dispenser only delivers water from the water bottle source, so if there are no water bottles available there is no water available in the dispenser.
• In most areas, water service is fairly inexpensive however, and come with a periodic inspection of the tank along with delivery of fresh, filtered water.
• Bottled dispensers are made to use pre-filtered bottled water, so they do not usually have or need a filter inside.
The bottled water dispenser has many of the same components as a point of use dispenser, as they contain many similarities and are built the same way. Although, there are simple bottled water dispensers that do not have any cooling or heating options. Typically, a bottle water dispenser has the following parts:
• A tank (or two)- to store the water to be heated or cooled prior to dispensing.
• A water heater- to heat the water
• A refrigerating system- to cool the water.
• A tap or spigot- to release water
• A button or knob- for users to dispense water
• A collar- which holds the water bottle in a downward position, and allows water to channel into the tank(s.
• Electricity is required, if the dispenser has the option to cool and heat water.
