What is a water cooler?

A water cooler is a device that, in addition to cooling the air, also does the work of air conditioning well. A water cooler with evaporative cooling, which means producing cool air by evaporating water, can make the hot summer weather more pleasant and bearable. Therefore, water coolers help to cool the air by consuming water and producing evaporative cooling. Actually, by absorbing the heat of the air, the cooler uses it to evaporate the water flowing in the cooler, therefore, the larger the dimensions of the cooler and the amount of water circulating in it, the cooling power of the device increases by the same amount.

What is an air conditioner?

An air conditioner or split is one of the subsets of air conditioning equipment, which works like a water cooler by electric energy (electricity), but in terms of components and cooling system, it is completely different from a water cooler. Generally; All air conditioners work based on the compression refrigeration cycle. First, the refrigerant is cooled in the outer part of the outer panel of the air conditioner (condenser) and is transferred to the expansion valve through a copper pipe, and from there it enters the coil of the inner panel as a refrigerant gas to absorb the ambient heat. becomes After passing through the coils of the internal panel (evaporator), the air inside turns into cool and pleasant air and brings comfort and well-being to the residents.
Comparison between water cooler and gas cooler
Deciding which type of cooler is more suitable for your consumption, depending on the difference between a water cooler and a gas cooler, depends on various factors that you need to know to make a better choice, such as the performance of water and gas coolers, Types of water and gas coolers, the use of coolers and the initial cost of buying each of them.

Application of water cooler and gas cooler

The most important difference between a water cooler and a gas cooler is the difference in the use of these two types of coolers. In general, evaporative cooling (water) through water coolers is a common and optimal way to create cool air in the environment (provided that the relative humidity of the air is less than 40%).
It is usually recommended to use water coolers in cities with hot and dry weather. As you know, in this method, by creating humidity in the environment, in addition to providing the required cool air, the water cooler prevents the air from drying out, cracking wooden items, and creating static electricity in these areas, and in addition to cooling, it also helps to soften the air in the environment. does
Therefore, in general, in a scientific comparison, it can be said that air conditioners and splits are used in hot and humid areas (Sharji) and water coolers are used in dry and temperate areas to create cool air.

Types of EVAPORATIVE COOLERS and SPLIT AC UNITS

In this part, we are going to get to know the types of water coolers and gas coolers.

Types of Evaporative Coolers

• A portable or mobile water cooler, as its name suggests, can move and be portable. The tank of this cooler can either be filled manually or it can be directly connected to the hose and faucet.
• The fixed water cooler, which is the most common type of water cooler, is installed on the roof or terrace or sometimes in the yard due to its large dimensions, and with the use of proper ducting, you can benefit from its cool air. Stationary water coolers are divided into two general types, conventional water coolers (with a fan) and cellulose water coolers, in terms of how they cool the air.
• The industrial water cooler is also used as one of the most widely used cooling equipment in workshops and spaces with larger dimensions than apartments and houses. Industrial water coolers can have a cellulose pad like a cellulose cooler or a cover like traditional coolers.
• Cellulose water coolers use cellulose pads instead of cloth, which provides a better and more continuous supply of cool air in cellulose coolers due to the volumetric consistency of cellulose compared to cloth. Using a cellulose pad instead of a pad in water coolers, due to the property of absorbing more water than a pad, as well as placing regular, wavy, and uniform layers of cellulose together, uniform distribution of water on the cellulose pad, and as a result, there is the largest contact surface. effective between the passing air and the wet surface of the cellulose pad, it creates more coolness (about 2 to 3 degrees Celsius more than coolers with a cover) and does not transfer airborne particles and bacteria into the cooler channel.
• Water cooler with propeller or an axial ventilation fan, in this type of water cooler that is placed directly in the window, there is only the possibility of direct ventilation without the possibility of air passing through the channel. (Generally, the installation of a centrifugal fan in fixed water coolers is done to overcome the pressure drop of the air passing through the air channels of the cooler), but if you want to use the water cooler directly and without ducting for any place, you can use types of water coolers with axial (window) fans, whose price is almost half of the price of common water coolers. (Of course, don't forget that to supply fresh air to these water coolers, these coolers must be installed directly on the edge of the window or the wall of the building's exterior space.)

Types of  Split AC Units

• The window air conditioner is the simplest type of air conditioner that is designed and produced in one piece, that is, the compressor and condenser parts with the cool air panel are located together in one box. These types of coolers have a small and compact design and are often installed on the window of the room, which you must have seen many times. That is why they are called window air conditioners. Of course, you must know that the back of the air conditioner must have access to the open space so that the hot air behind the device is pushed out.
• A portable air conditioner, like a window air conditioner, has all the parts in its box and is a piece of cloth. The reason for the name of these coolers is that they are portable and not attached to the wall or ceiling, and in some cases, they have wheels that make them easy to move around. Small portable air conditioners are suitable for small environments such as bedrooms, offices, and small shops, and medium portable air conditioners are suitable for commercial offices and medium rooms up to 15 square meters.
• Air conditioners and wall splits, which are produced and supplied with a capacity of 9000 to 30000 BTUs, consist of two units, an internal unit, and an external unit. The external unit consists of a compressor and a condenser that is installed outside the building. The indoor unit, which is a cooling panel (evaporator), is placed inside the building and on the wall. These two units are connected by two copper pipes.
• Standing air conditioners: standing split air conditioners, which are manufactured and supplied in capacities higher than 40,000 and less than 90,000 BTU, are mostly used in banks, mosques, exhibitions, restaurants, and large spaces.

EVAPORATIVE COOLER and a SPLIT AC UNIT performance

Some air conditioners, in addition to the function of cooling and cooling the environment, also have the ability of heating in the cold seasons of the year. Air conditioners with these two functions, like other air conditioners, consist of 6 main parts: compressor, expansion valve and capillary tube, condenser, evaporator (internal panel), four-way valve, and refrigerant gas, which help to heat and cool the environment. They do.

The initial cost of the EVAPORATIVE COOLER and a SPLIT AC UNIT

The difference between a water cooler and a gas cooler can be mentioned in their price, the price of a water cooler and a gas cooler is different based on the type of capacity and brand, but even though the cooling quality of gas and split air conditioners are more pleasant, this point should be taken into consideration. Please note that usually the initial price and cost of buying and equipping a split gas air conditioner is more than 4 to 6 times the initial cost of buying a water cooler for the desired space. To choose and buy easily, you must first determine the brand and required capacity. On the site of Damatajhiz's specialized collection, technical information of dozens of models of water coolers and gas coolers, from reputable brands with original warranties, has been presented for you to enjoy the good feeling of optimal and smart shopping.
