A cooler is a special device for cooling and heating bottled drinking water. The English word cool is hidden at the root of the name. No wonder: the first models could only pour cold water. Technology has stepped forward, and modern coolers are able to heat water almost to boiling water (96 ° C), allowing you to prepare hot drinks right on the spot. Especially coolers are in demand in public places, offices, business centers. Often people buy water machines in their apartment or private house. This is not only an economical and functional solution, but an interesting element of the interior. The variety of models is so great that it is not difficult to choose a device that suits the design. The main thing is not to get confused about the types of coolers, understand how they work, and use them wisely.

How the cooler works

The water cooler consists of two tanks, between which is located separating check valve. Also, the design assumes the presence of a plastic bottle (up to 30 liters), a dispenser and a connecting pipe. After installation, the bottle of water is sent to the dispenser distribution system (tanks for cold and hot water). First, the liquid enters the cold water compartment, then flows through the connecting pipe into the boiler with heating elements. Between these two compartments is a check valve. This is the most important element of the design, as it establishes a balance in the system, and the cold and hot flow do not intersect.

How the cooler works

Important! The power consumption of the cooler per day is 500-1000 W, yielding even to an ordinary electric kettle.

To better understand the principle of work, you need to understand the difference between some models from others. Coolers differ in functionality, performance, method of installing a bottle of water and cooling method. There are models with compressor and electronic cooling.

Compressor models

The compressor-type water cooler device is similar to a household refrigerator or split system. Inside the case, in an isolated chamber, a compressor is installed that compresses the freon refrigerant. A radiator grille is attached to the back of the instrument for cooling.

Radiator grill recommended protect from damage and shock. If cracks and kinks appear on its surface, freon may leak. Anyone who has dealt with a refrigerator repair knows the consequences of a leak: the cooling system simply fails. Repairing the device, of course, is real, but laborious. After all, first you need to find microcracks, then solder the damage and pump in a fresh portion of the refrigerant.

Compressor cooler

With careful handling and integrity of the radiator panel, the compressor cooler will last a very long time, and you won’t have to regularly pump freon. This type of device is not only durable, but also productive – at least 2 l / h. The water temperature will be kept at 5-10°C.

Compressor models have impressive dimensions and, as a rule, have a floor installation. They are more difficult to transport from place to place, because transportation is possible only in an upright position.

Advice! Compressor-cooled machines are best suited for a large office, where water consumption for 10 people can reach 20-25 liters.

  • excellent performance;
  • durable operation;
  • effective liquid cooling – up to 5°C;
  • the device is not afraid of heat;
  • some models have a built-in refrigerator;
  • cooling temperature can be adjusted.
  • high price;
  • impressive dimensions;
  • high noise level;
  • easy to damage the grille.

Electronic Models

The electronic cooling technology is based on Peltier effect. Its essence is as follows: the liquid in the tank is cooled by a thermoelectric semiconductor module. The module consists of several bonded thermocouples located between two plates. When an electric current passes through the thermocouples, the first plate cools, the second heats up (it is called the Peltier board). The cooled air from the board is drawn in by means of a built-in electric fan.

Peltier effect

The cooler with electronic cooling is an easy-to-use and compact device. It rarely gives technical failures, but requires special storage conditions for stable operation.

Important! In the room where the device is installed, there must always be clean air and a minimum of dust. If the fan inside the structure becomes clogged with dust, then the entire device will quickly fail. Also, performance may be impaired in the hot season, if the air temperature in the room exceeds 26-28 ° C.

Electronic cooler

An automatic cooler with electric cooling most often has desktop installation type. The average output is about 1 liter per hour and the minimum cooling temperature is 10-15°C. The device is suitable for home use, use in a small office or office. It is desirable that there is air conditioning in the room with the cooler.

  • profitability;
  • ease of operation;
  • compactness;
  • high ecological properties;
  • transportation in a horizontal position is allowed;
  • quiet work.
  • low performance;
  • unstable work in the heat and in a poorly ventilated area;
  • slow cooling of the liquid;
  • it is not possible to install a built-in refrigerator.

Types of water coolers

At the word “cooler” most people think of a huge bottle with a dispenser for supplying water. Who would have thought that choosing a cooler is a laborious and difficult task. Manufacturers produce several types of devices, which vary greatly in purpose, installation and control methods.

floor cooler

They are actively purchased both in the office and in the house. As a rule, are standalone and take up quite a lot of space. The floor cooler resembles a narrow cabinet just below a standard refrigerator. The design can be any, the color of the case too. There are models with bottom or top loading of the bottle (the bottle is installed directly above the water dispenser).

Floor coolers have many functions in their design, high-quality heating, and there is always powerful cooling. Productivity is also high here – this is due to compressor cooling method. Due to the high water supply rate, a floor-standing apparatus is preferable to choose for large institutions, offices or industries.

Outdoor cooler

desktop cooler

The desktop version usually has small dimensions, therefore it is suitable for home use. Sometimes such coolers are installed in offices with a small team and, accordingly, low water consumption. Installation requires a table, window sill or some kind of stand. The most important thing is that the surface is durable.

The devices can have many additional options, cooling and heating water, as well as a different design. The most popular among desktop units are budget models with electronic cooling.. Their performance, although small, is quite sufficient for the home. They cope with their tasks, look compact and do not hit the wallet.

Cooler with cabinet

Appliances with a cabinet provide a space where you can store kitchen utensils, containers, cups, as well as non-perishable products (sugar, salt, flour, etc.). The presence of a compartment is a practical and cost-effective solution.

More advanced coolers equipped with an ozonator. If you start the built-in timer, ozonation will occur inside the locker for a certain time. Ozone creates an antibacterial space: it kills bacteria and pathogens. In such a locker, you can fearlessly store food.

Cooler with refrigerator

A cooler with a built-in refrigerating chamber is an energy-efficient technique with high efficiency. All such models have compressor type cooling, and the energy of the compressor is spent on the food storage compartment. The temperature inside the chamber can be adjusted. For example, set the night mode – more economical, but maintaining acceptable coolness. Most often, models have a display showing the current temperature inside the chamber.

Cooler with refrigerator

A cooler with a refrigerator is useful for use in the office. The refrigerator compartment can use as a minibar, store employee lunches, juices, dairy products in it. Of course, such a cooler is not a replacement for a full-fledged refrigerator. It must not be overloaded, otherwise the cooling system may fail. As a rule, the volume of the chamber does not exceed 20 liters, but there are models with an extended chamber of 50-60 liters. Inside there are shelves (one or two).

Embedded cooler

Another interesting option for saving space in the room. It can be built into a kitchen set or into a special niche in the wall. A bottle of water is installed behind the cabinet door or inside the headset. The bottle is connected to the dispenser using long flexible hose. From the outside, everything looks aesthetically pleasing and modern: users can see only the working panel of the cooler with push-button or, most often, touch controls.

If you buy a device with cooling and heating, then there will be no need to use an electric kettle. A built-in water cooler is worth choosing for owners of small companies. It is easy to install and maintain, will not disturb the unity of the kitchen interior design in the office or at home.

Built-in cooler

flow cooler

In flow-type devices, water does not come from removable bottles, but from a water supply system, a well or a well. This is beneficial from a financial point of view, because the cost of tap water is lower than that of bottled water. And due to the lack of a bottle and connection to the water supply system, you will not be limited in water consumption.

Important! If there is an autonomous water supply, then an additional pump will be required to connect the cooler. The pump is necessary to create sufficient pressure in the system. If the pressure is too low or too high, the heating equipment may be damaged.

The flow cooler has built-in treatment of incoming water. According to the principle of operation, the cleaning system resembles a home filter. Some models have the function of disinfecting water from bacteria and harmful microorganisms using ultraviolet radiation. Internal filters should be regularly checked for contamination and replaced as scheduled. The flow filter has solid dimensions and high cost. Subsequently, the cost of acquiring the device quickly pays for itself.

Gas cooler

Drinking cooler can be equipped with a carbonizer (or saturator). This is a device that saturates water with carbon dioxide. As a result, you can get real carbonated drinking water. To start the carbonizer, you will need a container with food carbon dioxide. Gas cylinders are disposable and rechargeable. A standard cylinder contains 5 liters of carbon dioxide. This volume is enough for 180-200 liters of sparkling water. Apparatus with aeration refers to the floor type.

Despite the interesting functionality, these coolers are less popular among users. In large institutions and public places, most people prefer to drink plain cold or hot water.

Gas cooler

baby cooler

A water cooler for children is a simple and understandable device that will teach your baby to drink clean water regularly. This little cooler has bright body and design in the form of a toy. So, in an easy game form, you can teach children to drink the daily rate of liquid. Parents can control the drinking regime every day. The children’s mini-cooler has compact body dimensions with a bottle volume of no more than 2 liters. It does not require a power supply to operate. A baby cooler is rarely equipped with heating or cooling and is used primarily to supply liquid to a mug. By the way, in addition to water, other drinks can be poured into the cooler, such as juice or compote. The liquid is supplied by pressing the mug on the lever. Most likely, the child will quickly master this device and will independently pour drinks during the day.

Cooler for kids

Advice! If your family has small children, but you want to purchase a regular home water cooler, then look for a model with a protection function. So, protection is placed on a hot water faucet. You have to use both hands to open it. Otherwise, blockage will occur and water will not be supplied. This feature will protect children from accidentally spilling boiling water.

How to use the cooler

After purchasing the cooler, first read the enclosed instruction manual. If you know how to properly use a water cooler, you can avoid a huge number of breakdowns. Here are some simple requirements for cooler operation.

  1. The new device must be checked for damage and cracks. Carefully inspect the case and make sure that all components are in place.
  2. Choose a place to install the device. The surface must be level, dry and stable. This is especially true for desktop coolers, which are light in weight and compact in size. If such a cooler is on a fragile surface, there is a risk of falling from a height and mechanical damage.
  3. Do not lean the cooler too tightly against the wall. To ensure air circulation between the wall and the apparatus, there must be a gap of at least 15 cm.
  4. Please note that the new device can only be connected to the network after filling with water. Otherwise, the heating element may burn out, and this situation does not even belong to the warranty category.
  5. The next step is to attach the bottle. For coolers top loading bottle the procedure is the following. Remove the protective sticker from the cork (or carefully pierce the cork). Carefully turn the bottle upside down and insert it upside down into the dispenser slot. Wait a few minutes until the water stops flowing into the cooler. Make sure there is no air pocket inside. Take the empty container and drain the water from the hot and cold taps of the cooler (about 500 ml from each). This is necessary to flush the new instrument.
  6. At devices bottom loading bottle everything is much easier. It is enough to attach the water intake to the bottle and plug the cooler into the outlet. Make sure that the power button remains in the “off / off” position. Then press the button and close the bottle compartment door. The cooler tank will fill with water in about 20 minutes.
  7. As a rule, immediately after switching on, the indicator lights on the case light up: red for hot water and blue for cold. It will take about half an hour to cool down, a little less to heat up. So, the water temperature will reach 85 ° C in about 15 minutes. After the end of the action, move the button back to the off / off position.
  8. If the machine is not used for a long time (more than 3 days), it is recommended to unplug the power cord from the outlet.

Basic maintenance of the cooler is the actions that must be performed in order to maintain the performance of the device. Do not forget to clean the outside of the case from dust. When the machine runs out of water, it is necessary to re-install a new container.

Attention: never turn on the cooler without a bottle of water. If the water is over, it is better to wait for the delivery of a new bottle.

Don’t forget to arrange regular disinfection and cleaning of the water cooler – at least 3-4 times a year. Prevent scale formation and bacterial contamination. With the removal of scale, a solution of vinegar or citric acid of low concentration does an excellent job. Microorganisms inside the structure are destroyed with solutions based on iodine, chlorine, ammonia. However, it is best to entrust disinfection to specialists by contacting the cooler manufacturer’s service center.


Soon after buying a cooler, you will see that it is a very functional device. It will cool and heat water at any time you need. Additionally, the device is able to maintain the temperature at the required level, prepare soda or generate ice. If you follow the basic rules for operating the device, take care of the dispenser and change the bottles on time, the device will last for more than one year, recouping its initial cost many times over.
