Water cooler: characteristic, choice, overview

click fraud protection

The quality of drinking water from a tap in many localities often does not meet the standards. People always have the right to choose - to drink tap water of questionable quality, or to buy a water cooler.

Water dispenser( common name - cooler) is designed for water distribution. It also has a number of additional functions: filtration, cooling or heating of water, as well as its aerating.

The first prototype of the classic cooler was invented in the USA and was called the "drinking fountain".It was invented by a certain Taylor, in a difficult time for his family, when his father, having drunk dirty water, died of a terrible illness - typhus. The popularity of the device grew and already in the early 19th century the production and sale of coolers for water acquired a serial nature.

Each year the coolers have been modified and improved. So, in addition to the main function - the supply of clean water, the plants could cool water. Hence the common name "cooler", derived from the English word "cooler" - cooling. And a little later the instruments "learned" not only to cool, but also to supply water heated to 90oC.Similar devices are installed in offices and educational institutions. Now you can buy a water cooler for your personal use.

Types of water dispensers

Externally the standard water cooler looks like a plastic casing with two taps and a funnel for a water bottle. On the front panel there are indicators of cooling and heating water. The device operates from the network, and consumes a minimum amount of electricity due to built-in sensors. As soon as the water temperature is cooled / heated to the desired temperature, the sensors turn off and the cooler goes into standby mode, during which the electric power is not consumed. There is an opinion that for safety reasons water dispensers of this type should be switched off for the night, but many office workers neglect this rule, and it should be noted that the average life of the devices is not reduced. But if you plan a long business trip or departure for a few days, in this case, the water dispenser should be turned off.

The distinctive feature of the dispensers is that the water temperature is maintained in the desired mode, and it does not boil until it boils, which allows maintaining the balanced mineral composition of the water.

Floor standing dispenser

Water coolers are floor and desktop. The floor water cooler is installed on a flat, flat surface, preferably on a table or floor. Dispensers work in automatic mode. On the front panel there is an indicator button that indicates the mode of operation of the device. The user, if desired, can turn on the cooler in cooling or warm water mode. If there is a long break in the cooler, it is better to disconnect it from the network.

There are models equipped with ozonation cameras built-in inside. This saves working time and uses disinfected utensils.

What are the advantages of floor models:

  • to install the cooler can be directly on the floor, which is especially convenient if there is not enough room in the room or there is not a separate table;
  • compact size allows you to install a dispenser even in a small room;
  • design floor cooler can be chosen at its discretion, so that it blends well into the interior of a dwelling or office;
  • cooler is used for heating and cooling water;
  • variety of models will allow you to choose the model you like;
  • availability of convenient additional functions with a system of carbonation, water filtration, built-in lighting and holders for cups. There are models of dispensers with 3 taps for water supply( 3rd - for filling large tanks with water at room temperature), working in the "easy pressure" mode, as well as blocking the tap of hot water;
  • models can have additional functions such as a mini-bar( built-in refrigerator), a cupboard for storing utensils, tea and coffee. A convenient new function is the ozonizer. All dishes that are stored in the cupboard will be disinfected.

Among the drawbacks of using outdoor models of coolers is to pay attention to the type of loading cooler - the lower or upper. If only women's staff work in the office, then it is better to choose a device with a lower load, since it will be difficult for a woman to lift a weight of more than 20 kg to replace a bottle.

Depending on what needs to be done with water - to cool or heat, the water dispensers can be electronic or compressor. Consider the distinctive features of each model:

  1. Compressor cooling:
  • it is possible to cool water at a speed of up to 3 liters per hour;
  • energy saving. Built-in temperature sensor and indicator will allow you to adjust the temperature and automatically turn off the device;
  • functionality - the outlet temperature is about 5-7 ° C.

  1. Electronic cooling:
  • coolers are distinguished by their durability and strength;
  • works almost silently, which is very important in the office environment;
  • absence of refrigerants indicates high safety, as the possibility of leakage is completely excluded.

The price of an outdoor water cooler can be an order of magnitude higher than the cost of a desktop water dispenser.

The popular water cooler model is available in several colors, which allows the user to select the device for their interior. The water cooler supports a wide temperature range: cold water from +5 to +10 ° C, and hot water - from +90 to + 95 ° C.

Desktop dispenser

The desktop water cooler is a classic version of a bottled water dispenser. It is a bulky plastic base, on top of which there is a container with water( 18.5 liters).If you buy such a cooler, you must first choose the installation site so that it is convenient to service it. In addition, it is worth paying attention to the strength of the base. Since the dispenser will be installed on the table( an alternative option is a shelf), the base must be strong so that the apparatus does not fall under the weight.

There are no design differences between the two types of water dispensers, but when choosing a desktop cooler design, you should pay attention to the fact that the bottle will have to be changed frequently, which means that microorganisms that can quickly multiply and accumulate can enter the internal pipeline of the cooler, andmeans to penetrate into the tank with water. This problem can be solved by purchasing a new generation tank with an ultraviolet lamp. It is installed inside the tank and destroys the bacteria. Naturally, the price of such a cooler will be an order of magnitude higher than the classical model.

When the system is not protected from penetration of microorganisms, if you disassemble the cooler after 6 months of operation, you can detect a slippery thin coating inside, which indicates active multiplication of microbes.

The replacement of the tanks is performed by the dispenser sellers as a service. This water is purified by the "reverse osmosis" method, when the water molecule "breaks through" the membrane, and all other large molecules remain. As a result, we use almost "dead" water, equated to the category of "technical".To enrich the water producers artificially saturate it with ions, calcium and magnesium. Naturally, talking about the benefits of water with 100% certainty is impossible. There is a way out - you can install a dispenser for running water and get quality drinking water from a water pipe through a filtration system.

Cooler for cooling and heating water. Advantages and disadvantages of

Consider the principle of compressor and electronic cooling. Compressor cooling is identical with the principle of the refrigerator. The cooling component( freon) absorbs heat during evaporation. When the compressor is cooled, the water temperature does not drop below 5 ° C, and the final result will not depend on the ambient temperature. Also, the cooling temperature can be adjusted independently. Among the drawbacks of compressor cooling are noted: noise, as in the operation of the refrigerator, and compliance with transportation rules( transportation only in vertical position), as a leak of coolant is possible.

When the water is electronically cooled, the current passes through the conductors, which are cooled at the interaction points. For the first time in the 18th century, such a relationship was discovered by the French scientist Peltier. Subsequently, its development was taken as a basis.

Among the advantages noted durability and performance, noiselessness, the ability to transport in any position and inexpensive cost of the cooler.

Disadvantages of electronic water cooling - low productivity( 6 glasses per hour).Some models, for example, the water cooler Ecotronic has 2 cooling units. This allows to increase productivity to 2 liters per hour.

Dispensers with electronic cooling should not be installed in poorly ventilated rooms with a high temperature.

The water cooler serves as an electric kettle. But if in the kettle the water heats up to a boil, then the water dispenser does not allow it to boil. Prepare from the water of this temperature hot drinks( coffee, tea) is quite possible. This function differs not only in terms of convenience in terms of preparation of drinks, but also allows you to store all the useful substances in the water. Such functions have a cooler for water Notfrost.

Flow Dispenser

The names of the apparatus can be several: a purifier, a flow cooler or a water purifier. A distinctive feature of a flowing water dispenser is that the source of water is not a replaceable bottle, but ordinary tap water. The dispenser is equipped with a water purification system, similar to the filtration system for water pipes( minifilters are installed in the kitchen under the sink).Such filtration differs from bottled water, first of all, by good quality. The principle of water purification is carried out in the same type of "reverse osmosis", only in the development of the filtration system for flow-through coolers, all shortcomings were taken into account, and as a result, we have quality water without microorganisms, foreign smells, chlorine and other harmful impurities.

In addition to water quality, the appearance of the flow dispenser differs significantly from desktop models in small dimensions. If you install such a cooler in the office or at home, then dependence on suppliers and the problem of storage of empty containers will be decided forever.

etc

Among the cons are worth mentioning only one - the cost of its own water filtration system will be much higher than the acquisition and maintenance of floor and desktop coolers.

When choosing a cooler, think about its safety, because each dispenser is connected to electricity and connected to water. Therefore, when operating the device, it is important to observe safety rules, to avoid the drop of the device and ignition of the wiring in case of a short circuit.
