Translate the word "cooler" can be different. Wikipedia gives the three basic values. One or connected with the beers, the other - from the computer, the third cooling - with drinking water. We will only be interested in the latter. So, the cooler - a device that can be dispensed to pour water to drink.
The machine has become so popular that it can be found everywhere. In schools, gyms, public reception and even apartments. The biggest spread of the equipment available at the office. But even daily confronted with this device, very few people know how the device works and what can separate models.

What is cooler
Why do I need a cooler, when you can open the tap and collect the right amount of liquid? but in the case of the cooler talking about purified drinking water of the highest category. This water does not go through the pipes, and packaged in a special container.
Average bottle for purified liquid has a volume of 19 l. And there is 30 liters. Pour out of it in a glass or mug would be extremely difficult. Many can not even pick up the full container. But once is enough to set the bottle into a special apparatus and can be for a few days or weeks to pour out of the machine right amount of water.
reference. Such heavy tanks do not need to drag yourself from the store. Targeted delivery takes a company specializing in water treatment. Their staff are not only ENTERED bottle in the apartment, but also the right to install it on the cooler.
In the unit there is another functionality. The device has two valves - each of the fluid flows at different temperatures. The cooler housing is composed of two water tanks. In one of them there is a constant cooling in the other - the liquid is heated.
Besides support temperature in each tank is automatic. For example, when the maximum setpoint device itself disables the heating element. But as soon as the degrees drop to the specified minimum, the unit will start to heat the water again.
Most aggregates liquid is adjusted almost to boiling water (+ 96 ° C). This is the ideal temperature for creating refreshing drinks (tea, coffee). And the automatic mode allows you to not wait a single second, and immediately drink a drink. This significantly saves time, allowing you to use it more productively. But even better to understand what is cooler, it will help the study of the operating principle.
Principle of operation
Typically, the device has a plastic housing in which are situated tanks for hot and cold water. Between them there is a check valve. This element maintains the balance in the system and does not allow hot and cold streams intersect.
The purified liquid from the bottle enters the distribution system. First fills the cold tank, and then flows through the conduit to the tank for heating. In the last set heating element. Typically, this heater in a sheltered housing.
The cooler device for a water cooling circuit includes a description that can be realized in two ways. Each of them has its advantages and disadvantages. Since compressor model similar to a refrigerator. On the back wall they have a grill to cool the refrigerant. And the refrigerant in the system runs via the compressor.
The positive characteristics of such structures:
- high performance;
- liquid cooling to + 4 ° C;
- long service life;
- model can be equipped with a small refrigerator;
- possible adjustment of the water temperature at the outlet.
Disadvantages of the system:
- high price;
- large size;
- noise at work.
An entirely different principle of operation of the water cooler which employs the Peltier effect. Cooling is a thermoelectric module, semiconductor. The system uses multiple bonded thermocouples. They are located between the two plates. When electricity is supplied to a pair of one of the plates is strongly cooled and the other heated. Cold air is routed to the correct container by a fan.
The advantages of the electronic device:
- small size;
- saving;
- quiet operation;
- ease of use;
- environmental friendliness.
Disadvantages of the system:
- low productivity;
- the liquid is slowly cooled;
- Do not install in a stuffy and dusty environment.
Additional options coolers
Current models provide even greater functionality, as well as different species for ease of use. For example, floor construction typically installed in offices. They allow you to use more capacious bottles, which significantly increases the time between their replacements.
It is usually more efficient models that can serve more people at a time, and giving cold and hot liquid in the required amount without delaying anyone. Therefore, these aggregates have a large size and need to separate free area. The size and shape they resemble a refrigerator, only narrower.
The structure may be present both upper and lower loading of bottles. Also, some models are equipped with cabinets for various dishes and non-perishable products. Such as sugar, tea or coffee. Besides simple storage function, such compartment can be fitted ozonator. This device carries out disinfection of the surrounding space, creating a locker antibacterial zone. After this treatment, products and dishes retain their freshness longer.
Note! Install outdoor cooler is recommended in a free zone, to them was an open passage. Usually it lobbies of large buildings or special lounges.
Table model a home, but can be successfully used in small officesWith small groups. Design copes well with heated water for hot drinks. Also able to cool the liquid and normally uses this electronic method. Though it is less productive, but is best suited for a small number of people. Because it is more economical.
This design has a small footprint and can be placed even on the windowsill. But it is usually placed on a desk or a special cabinet.
For offices available models with built-in refrigerator. Of course, the full function of the refrigerator, they will not be able to perform, but to preserve the freshness of the products are capable. Usually you can find a small camera, only 20 liters. But there is a larger design on 50-60 liters. Inside there are shelves on which employees can store their lunches.
Such a It relates to energy efficient appliances with high efficiency. It is used for cooling the compressor and the temperature can be controlled even. For example, put a night mode, which will be supported by a slight coolness. This will save power consumption.
For those who fight for every centimeter of usable space, will be interesting modelWhich can be built into a kitchen cabinet. When this bottle is installed separately in another place, and its connection to the dispenser takes place through a long hose.
increasing popular are types of coolers, which are called flow-through. Their main feature is the absence of a bottle. The dispenser is connected directly to the water supply system in the house. This suggests that the system has its own water filters. In some cases, it should doukomplektovyvatsya pump to create the desired pressure.
Basically such a system resembles a home filter, since many models are equipped with the possibility of disinfection using ultraviolet lamps. The design is quite cumbersome and requires space. Also requires constant monitoring of the condition of the filter and the regular replacement of them. Such equipment is expensive. However, the initial cost is quickly recovered, and then the system only brings savings.
Some interior design equipped saturator. This device is able to aerate the water. To implement the required installation of a gas cylinder, which is disposable or rechargeable. Volume of carbon dioxide is 5 liters enough to zagazirovat 200 l purified water.
For kids produced a mini-cooler, with the body in the form of toys. These devices are designed to teach the child to drink only purified water. For those who are curious, how many liters in a cooler for the children will be interested to know that they are not set large bottle. For small apparatus taken simple two-liter container, which can not only advance to pour water. For children the apparatus has only one tap, which is activated by pressing the cup and outputs juice, compote or water at room temperature. You can adjust the device to a small heater.
If the house is small children, it is recommended to buy a cooler with protection. In such a device, to open the hot tap is necessary to use two hands simultaneously. This measure can save a child's health and protect him from possible burns.
How to choose a cooler for home
Particular requirements for appliances for home use is fundamentally different from the requirements for office structures. We do not need high performance, as well as the presence of a refrigerator. By ozonation can also be abandoned because there is no danger that the device can use an outsider, wearing pathogens.
Here are 5 rules for selecting the device for home:
- The best is a desktop device with electronic cooling system.
- If you want to buy the machine with filtering system, then let it be a multi-stage.
- When the house small children, it is desirable to present in the cooler UV lamp and protection on the hot tap.
- It is necessary that the water temperature suited all households. For hot drinks it should be + 96 ° C, and in the cold to + 4 ° C.
- Welcomed the presence of the timer and dispenser.
compressor model
Among the compressor device customer reviews note the model AEL TC-AEL-31. She has a good presentable appearance, to the same compact. Apparatus for a compressor which provides the temperature range from 10 to 90 ° C, it performs an undeniable advantage. One hour of the work unit is able to cool the 2 liters of water and heat the whole 5. But that's the price of 11 000 rubles may not suit all.
Ecotronic H1-T differs stainless steel tank. Compressor allows one hour chill 3 liters of fluid to + 5 ° C. During the same time it brings 5 liters of water to + 94 ° C. The device is protected against leaks, but, unfortunately, it is not by children. The average cost of the unit is very heavy (12 kg) - 8700 rubles.
good for flooring has established itself Ecocenter G-F4EC. The model has an upper loading bottles and cupboard. But still it looks quite compact. Can quickly cool and heat the water. Also beautiful appearance, characterized by low price - 6 500 rubles.
electronic devices
Among devices with electron cooling, leading HotFrost D65EN. It can heat the water to 4 L + 90 ° C for one hour. During this same time cools only 0.6 L and total up to + 10-15 ° C. But the unit cost and has protection against children. Weighs 4 kg and you can buy it for 4500 rubles.
E-filling and Aqua Work 36-TDN-ST. Device for the previous five hundred expensive, but can cool one liter of water to + 12 ° C for one hour. A heated to + 90 ° C is much longer - much as 7 liters. But his work consumes a lot of electricity, so the category of cost-misses.
To + 95 ° C warm water model capable Ecocenter T-T32EC. An hour is treated with 5 liters. But her electronic system can cool for this time only half a liter of liquid. But the device is different economical and low price - just over 4000 rubles. Its highlight is the bay of disposable cups.
conclusion
Cooler water contributes to the preservation of health, and is used both in a narrow family circle, and for a lot of people in offices or public places. When you select the device pay attention to its performance and functionality. Modern phones can perform several additional tasks that make use of the cooler even more useful.
