A water cooler or water dispenser is a device that cools and dispenses water. They are generally broken down into two categories: water cooler and bottled water cooler. The water cooler is connected to the water supply, while the bottled water cooler requires delivery (or self-pick-up) of water in a large bottle from the vendor. The water cooler that is connected to the water supply can be in a variety of styles, ranging from a combination unit of water cooling to bottle fillers, bilevel units, and other styles. Bottled water coolers often come with the 5 or 10 gallon dispensers most commonly found above the unit. The pressure cooler is a water cooling subcategory that includes a water fountain and a direct pipeline water dispenser (POU). Cooling water can also refer to primitive devices to keep water cool.
Water cooling is a common metonym that refers to workplace socialization.

Wall-mounted/recessed
The wall-mounted type connects to the building water supply for continuous water and electricity supply to run the cooling unit to cool the incoming water, and to the building waste disposal system to dispose of the unused water. Wall-mounted water coolers are often used in commercial buildings such as hospitals, schools, businesses, and other facilities.
In refrigerators mounted on standard walls, also commonly referred to as a fountain or drinking fountain, a small tank inside the machine holds cold water so the user does not have to wait for cold water. Water is sent by rotating or pressing a button on the spring valve located at the top of the unit, which turns off the water when it is released. Some devices also offer large buttons on the front or side. The newer machine may have no buttons at all; instead, sensors that detect when a person is close and activates water. Water is sent in an upward-curved stream, allowing the user to drink directly from the top of the water flow. These devices usually emit water directly from the city's water supply, without treatment or filtering.
The wall water cooler consists of a variety of styles, ranging from hidden models to splash resistant, contoured basins protruding from walls, traditional round square edges, bottle fillers and water cooled combination units, two-tier designs, and other features and options.
Bottom-load water dispenser
The most common water dispenser is that has the bottle on top. Bottom-load water dispensers eliminate the need to lift heavy water bottles. Instead, a water bottle is placed at the bottom of the dispenser.
Tabletop water dispenser
There is also a smaller water dispenser version where the dispenser can be placed directly on the table.
The water dispenser can be directly connected to the water source at home to constantly expend hot and cold drinking water. This type is usually referred to as POU water dispenser (Point of Use). It's more hygienic than bottled water.
Freestanding
Freestanding designs generally involve water bottles placed in dispensing machines.
Available versions of kitchen or kitchen tables utilizing five-liter water bottles are available from supermarkets. This cooler uses an air pump to push water into the cooling chamber and the Peltier device to cool the water.
New developments in the water cooling market are the emergence of desk appliances that connect to electricity and provide instant supplies not only cold water but also hot water and boiling water.

Water source and purification
Bottle
To install the bottle, the bottle is reversed and adjusted to the dispenser; a probe pierces the bottle cap and allows water to flow into the engine's internal reservoir. This gravity-powered system has a device to dispose of water in a controlled way.
These machines come in a variety of sizes and vary from desk units, which are intended for occasional use to floor-mounted units intended for heavier use. Bottled water is usually delivered to households or businesses on a regular basis, where empty bottles are exchanged for a full bottle. Bottle sizes vary by unit size, with larger versions in the US using 5-US-gallon bottles (19 liters). This is also the most common size elsewhere, labeled 18.9 liters in countries that use metric systems. These units usually have no place to dispose of excess water, offering only a small basin to catch a small spill. On the front, the lever or pushbutton dispenses water into the cup held under the tap.
When the water container is empty, it is lifted from the top of the dispenser, and automatically seals to prevent excess water remaining in the leaking bottle.
Refined with purification
Cooler water coolers use tap water and therefore do not need a bottle because they use the main water supply. Usually some purification methods are used.
Filtration
The filtration method includes reverse osmosis, ion exchange and activated carbon.
Cooling and heating methods
Cooling
Most modern units offer a cooling function to cool water, using vapor refrigeration or Thermoelectric cooling compression.
Compression of vapor compression
The water cooler using vapor compression refrigeration consists of the following components:
- Reservoir
- The RR technology is a removable reservoir that is an open-end tank with cooling coils that come into contact with the surface of the external tank. It operates on the basis of a modular system, allowing one to easily discharge and recharge water rather than storing it in a closed system. One of the advantages of using a removable reservoir is the ease of sanitation. This allows the end user to replace the reservoir completely rather than sending the entire water cooler back for service. Similar technology can be found in many modern water dispensers and coffee machines.
- Stainless Steel - open end tank with cooling coil in contact with external tank surface
- Pressure cooling tank - Pressurized tank with external cooling coil in contact with tank surface
- Es-bank - Pressurized water coil pipe seated in pre-cooled water volume
Heating
Some versions also have a second dispenser that provides room-temperature water or even hot water that can be used for tea, hot chocolate or other uses. Water in alternative hot water taps is generally heated with heating elements and stored in hot tanks (such as traditional hot water heaters used in residential homes). In addition, the hot tap is usually equipped with a push-in safety valve to prevent burns from accidental or accidental lever-pressing.
Water cooling effect
The water cooling effect is a phenomenon, occurring when employees at work are gathered around the office water cooler and chatting. It is a synonym for collecting and connecting people in certain neighborhoods (eg office). When a television program, like a soap opera or series, is talked about among many people (mostly related to guessing what will happen in the next episode) it can be said that the program has a water cooling effect.
