One of the processes that occur naturally and that is used for energy efficiency is the evaporative cooling. It is a natural process that uses water as a coolant in order to obtain efficient air conditioning or cooling. Thanks to the study of the operation of this process, it is possible to have much more efficient cooling in various areas.
In this article we are going to tell you all the characteristics, importance and usefulness of evaporative cooling.
Key features
Evaporative cooling is nothing more than a natural process that uses water as a coolant. This process is on which the principle of all refrigeration equipment, towers and condensers is based. These devices are used to cool fluids in all kinds of commercial, industrial and domestic applications. During evaporative cooling, all excess heat is released into the atmosphere through evaporation of the water. For this process to take place, contact between the water and a stream of air inside a heat exchanger is needed.
We know that this evaporative cooling is ideal for applications in which it is necessary to be able to reduce elevated temperatures. The advantage of this process over others is that it is possible to lower the temperature without excess energy consumption. Thus, It is a very profitable idea from the energy point of view and saving for the environment.
Utility of evaporative cooling
Thanks to evaporative cooling, there are numerous cooling towers, condensers and other devices that involve a fairly efficient alternative if we want to use the industrial cold sector. In this sector, machinery is used to lower the temperature and use environmentally friendly techniques that, in turn, require less financial investment.
Let's see what are the main advantages that the use of evaporative cooling can provide.
energy saving
As we have mentioned before, It is a fairly efficient procedure in terms of energy expenditure. The energy saving of energy consumption is related to the condensing temperature of the refrigerant used. If we have a typical installation, energy consumption can reach quite high figures, while in installations that have difficult evaporation action, energy savings of up to 45% can be achieved.
Less impact on the environment
Not only do we have energy savings due to efficient use of resources, but there is also a very low environmental impact. Thanks to evaporative cooling the greenhouse effect can be reduced considerably. This is due to the fact that greenhouse gas emissions such as carbon dioxide are indirectly limited. Thanks to the efficiency of the process, we see that less energy is lost due to the high efficiency.
Increased levels of security throughout
One of the questions of evaporative cooling is whether it provides greater safety compared to other cooling processes. It is an appropriate system for those indirect systems. Water cooling temperatures of up to 25 degrees or lower can be reached. This allows to use between intermediate heat forks that do not generate too high an energy cost.
Therefore, there are evaporative cooling equipment that reaches temperatures lower than those obtained in air cooling equipment. Therefore, you can see quite an interesting saving, although performance is seen more limited by the dry bulb temperature. With this technique, the condensation of the water in the refrigeration facilities is carried out at a suitable temperature. This temperature is perfect so that the pressure in the high sector of the refrigeration circuit is much lower. Low pressure in the refrigerant circuit reduces the risk of refrigerant leaks and the consequent potential environmental impact.
Another advantage that we can mention is a lower acoustic impact and a reduction in water consumption. Water is a very precious and increasingly scarce commodity on this planet. The effects of climate change due to the increase in the greenhouse effect that are causing droughts are more frequent and intense. For this reason, water is becoming increasingly scarce. With this type of process we can save on water and energy consumption. These two benefits provide better management of the environment.
Evaporative cooling applications
Let's see what are the different applications of evaporative cooling:
- Poultry industry: these systems are very important in poultry houses. During the hottest months of the year, poultry get quite hot. Thanks to the evaporative cooling system, the temperature and problems related to thermal stress can be reduced. In this way, we not only ensure that the birds have a better stay, but also improve the quality of the products.
- Farming industry: is another sector where this process can be used. Helps maintain a constant air temperature. Keeping this temperature stable is important inside a greenhouse. It is important to maintain a delicate balance of temperature based on energy expenditure in order to maximize production and minimize costs.
- Swine industry: To keep the temperature constant within a pig facility, the use of evaporative cooling is key. This provides a higher quality in animal production and better comfort for it. And it is that this system provides a more constant air temperature with higher quality.
- Dairy industry: it is another of the sectors where evaporative cooling has a place. Continued heat stress in cows can lead to decreased milk production. Thanks to this process, it is possible to achieve a high cooling capacity and minimize the loss of production during extreme peaks in outdoor temperatures. These peaks are usually reached during the late spring and summer season.
Conclusions
In short, we can say that evaporative cooling used as refrigeration applied in cooling towers, evaporative condensers, etc. They are characterized by considerable energy savings, greater safety and respect for the environment. This makes it an essential process in any part of the industrial cold sector.
I hope that with this information you can learn more about evaporative cooling and its benefits.
