Water cooler : characterization , selection , review

quality of drinking water from the tap in many communities often do not comply with the limits.People always have a choice - to drink tap water of questionable quality, or buy water cooler.

Water dispenser (common name - the cooler) for dispensing water.It has a number of additional functions: filtering, heating, or cooling water, as well as its carbonation.

first prototype of the classic cooler was invented in the United States and was called "drinking fountain".Taylor invented his kind, in a difficult time for his family when his father, after drinking dirty water, died of a terrible disease - fever.The popularity of the device has grown and in the beginning of the 19th century the production and sale of water coolers purchased serial character.

Every year coolers have evolved and improved.So, in addition to the basic functions - supply of clean water, the installation could cool the water.Hence the common name "cooler", derived from the English word «cooler» - cooling.A little later devices "learned" not only cool, but also serve to warm to 90 ° C water.These devices are installed in offices and schools.Now buy a water cooler can be for personal use.

kinds of water dispensers

external standard water cooler looks like a plastic housing with two taps and funnel bottle with water.The front panel indicators are cooling and water heating.The device operates from a network, and consumes minimal power with built-in sensors.As soon as the water temperature cools / heats to the desired temperature, the sensors are disabled and the cooler enters standby mode, during which the electricity is not consumed.It argued that for safety reasons water dispensers of this type, it is desirable to turn off at night, but many office workers ignore this rule, and it is worth noting that the average life of the device is not reduced.But if you are planning an extended business trip or leaving for a few days, in which case the water dispenser is best to turn off.

dispensers distinctive feature is that the water temperature is kept at the right time, and it is not brought to a boil, allowing you to keep a balanced mineral composition of the water.

Floor dispenser

Water Coolers are floor and table.Floor water cooler is mounted on a smooth, flat surface, preferably on a table or the floor.Work dispensers in automatic mode.The front panel has an indicator button notifies you of device operation.The user can optionally include a cooler in the cooling mode or the heating of water.If you have a long break in the cooler, it is better to disconnect from the network.

There are models equipped with cameras ozonation, built inside.This saves working hours and use sanitized utensils.

What are the advantages of floor models:

• cooler can be installed directly on the floor, which is especially helpful if the room is not enough space or a separate table;
• compact dimensions allow you to set the dispenser, even in a small room;
• design outdoor cooler, you can choose at its sole discretion, that it successfully entered into the interior of the dwelling or office;
• cooler is used for heating and cooling water;
• variety of models allows you to choose your favorite model;
• availability of convenient additional functions aerating system, water filtration, built-in lighting and holders for cups.There are models of dispensers with 3 taps for water supply (3rd - filling large containers with water at room temperature), working in the "easy push" mode and lock the hot water tap;
• models may be present, such additional functions as a mini-bar (built-in fridge), cupboard for storage of utensils, tea and coffee.A convenient new feature - Ozonator.All the dishes, which is stored in the cabinet will be disinfected.

Among the disadvantages of the use of floor models coolers should pay attention to the cooler feed type - low or high.If the office is working exclusively female staff, it is better to choose the device with a lower load as lift the weight more than 20 kg, to perform the replacement of the bottle, the woman will be difficult.

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

1. Compressor cooling:

• it is possible to cool the water at speeds of up to 3 liters per hour;
• energy savings.Built-in temperature sensor and indicator allow to regulate the temperature and automatically switch off the appliance;
• functionality - the outlet temperature is about 5-7oS.

Water cooler Aqua:

1. Electron cooling:

• coolers are durable and strength;
• operate almost silently, which is very important in the office;
• no refrigerant indicates a high security, since the possibility of leakage is completely eliminated.

cooler Aqua Water work:

outdoor cooler price of water may be much higher than the cost of a water dispenser desktop.

Hot water cooler model is presented in several colors, allowing the user to choose the device to its interior.Water cooler supports a wide temperature range of cold water from +5 to + 10 ° C and hot water - from +90 to + 95 ° C.

Table dispenser

Table water cooler - a classic version of the bottled water dispenser.It is a bulky substrate of plastic, which is installed on top of the tank with water (5.18 L).If you buy such a cooler, the pre-select the installation location so that it was convenient to maintain.In addition, pay attention to the strength of the base.Since the dispenser is mounted on a table (alternative - regiment), the substrate must be sound, to the weight of the machine is not dropped.

structural differences between the two kinds of water dispensers no, but when choosing a cooler desktop design should pay attention to the fact that the bottle should be changed frequently, which means that the inner fan duct can get microorganisms, which tend to multiply rapidlyand accumulate and thus penetrate into the water tank.This problem can be solved, if the purchase of a new generation of tank with a UV lamp.It is installed inside the tank and kills bacteria.Naturally, the price of this cooler will be much higher than the classic model.

When the system is not protected against the penetration of microorganisms, if you look cooler after 6 months of operation, it can be found inside a thin slippery coating, indicating an active reproduction of microbes.

replacement tanks operate as sellers dispensers service.This water is purified by the method of "reverse osmosis" when the water molecule "breaks" through the membrane, and all other large molecules remain.As a result, we use virtually "dead" water, equivalent to the category of "technical".To enrich the water producers artificially saturated with ions of calcium and magnesium.Of course, talk about the benefits of water with 100% certainty is impossible.Way out there - you can set the dispenser under running water and get high-quality drinking water from the water through the filtration system.

cooler for cooling and heating water.Advantages and disadvantages of

consider the principle of operation of the compressor and electronic cooling.Compressor cooling is identical with the principle of the refrigerator.The cooling component (freon) the heat absorbed during evaporation.When cooling water temperature of the compressor does not fall below 5 ° C, and the final result will not depend on the ambient temperature.Also, the cooling temperature can be adjusted independently.Among the disadvantages of the compressor cooling marked noise, both in the refrigerator and respect for the rules of transportation (transportation in an upright position), as there may be a leak of coolant.

When electronic cooling water current flows through conductors which are cooled in the field of interaction.For the first time in the 18th century this relationship discovered the French scientist Peltier.Subsequently, its development were taken as a basis.

Among the advantages noted durability and performance, silent operation, the ability to be transported in any position and the cost inexpensive cooler.

Disadvantages of electronic cooling water - poor performance (6 cups per hour).Some models, for example, water cooler Ecotronic has 2 cooling unit.This can improve performance to 2 liters per hour.

dispensers with electronic cooling undesirable installed in poorly ventilated subject to high temperature.

cooler water heating functions as an electric kettle.But if the water is heated in a kettle to boil the water dispenser does not allow it boil.Prepare a water temperature of hot drinks (coffee, tea) is possible.This feature is not only a convenience in terms of the preparation of beverages, but also allows to keep the water in all nutrients.These functions have Notfrost cooler water.

Flow dispenser

name from the device may be several: the cooler, the flow cooler or water purifier.A distinctive feature of the flow water dispenser is that the water source is not replaceable bottle, and normal tap water.The dispenser is equipped with a water purification system, similar to the filtration system for water (minifilters installed in the kitchen under the sink).Such filtering is different from bottled water, especially good quality.The principle of the water purification is carried out on the same type of "reverse osmosis", only the design of filtration systems for flow coolers all disadvantages have been considered, and as a result we have the output water quality without microorganisms, foreign odors, chlorine and other contaminants.

In addition to water quality, the appearance of the flow-through dispenser differs significantly from desktop models of small dimensions.If you install this cooler in the office or at home, it will be solved forever dependent on suppliers and the problem of storage of empty containers.

Among the minuses is worth noting only one - the cost of its own water filtration system will be much higher than the purchase and maintenance of floor and table coolers.

choosing a cooler, think about its security, because every dispenser connected to electricity and water connected.Therefore, the operation of the device it is important to follow safety rules, to exclude a fall of ignition wiring short-circuit.
