On hot summer days, temperatures rise in houses and apartments. A large number of residents suffer from the warm indoor climate. Accordingly, the desire for a cooling system is great. Cooling systems are used to cool the air in the room and save us from sweating in the summer. But hardly anyone still wants to buy a classic air conditioner. Burning eyes, stiff neck, headaches – experiences that many of us have in your office. In addition, there are the tiresome discussions about the setting of the air conditioning. One is too cold, the other too warm.
You can easily avoid this dilemma: Forget the conventional air conditioner and opt for a new way of cooling. In this article, we’ll explain which types of cooling systems there are, what advantages and disadvantages they have, and what you have to look out for when buying one.
Types of cooling systems:
In order for us to understand each cooling system, we must first look at the 3 types of heat transfer:
- Heat flow: This type of heat transfer is also called convection. Here, heat is transferred by flowing air.
- Heat conduction: Heat flows from higher temperature areas to lower temperature areas. E.G.: When water is heated in a saucepan, the saucepan also becomes warm.
- Thermal radiation: This is infrared radiation. This radiation emanates from an object or a body. The warmer it is, the more radiation it gives off.
These different types of heat transfer are also used in cooling systems. What heat transfer has to do with cooling? One uses the effect that heat always flows to cold areas. Some of the cooling systems on the market take advantage of this.
Cooling system #1 Conventional air conditioner:
It is based on the principle of heat flow (convection). The room air is cooled down to a certain temperature. The cool air sinks to the bottom and the warm air rises. Air circulation occurs within the room, which also causes dust to be stirred up and distributed throughout the room.
The abrupt change in temperature from warm to cold has a negative effect on our immune system and often leads to colds. The dust that is whirled up is particularly troublesome for allergy sufferers. In addition, conventional air conditioners are usually very noisy and consume a lot of electricity.
Cooling system #2 Surface cooling
With surface cooling , the room is cooled via the ceiling, wall and/or floor surface.
The way it works is similar to underfloor heating, only instead of the surface being heated, it is cooled. Pipes are laid in the surfaces through which cool water is passed. Conventional underfloor heating pipes are laid in a serpentine or spiral pattern.
When a person is in the room, he has a higher body temperature than the surrounding surfaces. Through the body it releases “excess” heat to the surfaces. The person slowly adapts to the new temperature in the room. Gentle cooling occurs. With surface cooling, in contrast to air conditioning, there is no influence on the air temperature. There is no draft and no fan. A natural exchange of radiation occurs.
Cooling system #3 egger system
The egger system can be used for wall cooling, ceiling cooling and floor cooling. However, you cannot compare the egger system with a conventional surface cooling system. It is based on the Tichelmann system. Instead of laying the pipes in a spiral or snake shape, we use parallel-running plastic pipes (so-called registers). The parallel arrangement of these pipes has the advantage that the cooled water cools the rooms evenly. The reason for this even cooling is the small distance between the registers (8 cm). You can hardly lay classic pipes of a surface cooling system so tightly. In addition, the water also has to travel a shorter distance. This way you can save on energy costs.
Cooling and saving energy costs: Is that possible?
Think your energy costs will skyrocket if you cool your entire house? No, because if you use the right system of surface cooling, you will not incur any energy costs.
How is that possible? You’ve probably noticed that in the summer, your basement is much cooler than the rest of the house. On average, a cellar has 15 degrees. The ground also has a similar temperature. Therefore, if you lay your pipe system in these places, you take advantage of the natural cold of the basement and the ground. The cooled water from the ground/basement is directed into the pipes laid in the house, cooling the rooms.
You use a heat pump for heating in winter? You can also use them for cooling in the summer. But please note that there are types of heat pumps that are suitable only for heating and not for cooling.
Why is the cooling system of surface cooling better than conventional air conditioning?
Better for health: with surface cooling, there is no spot blower. So no dust swirls around the room and the air is not dried out. This cooling system is particularly suitable for allergy sufferers.
Energy costs are reduced: If the cooling is operated passively via the ground or the basement, you have virtually no energy costs at all
Cooling without noise: You won’t hear the cool water flowing through the pipes in your home. The loud fan of the air conditioner, on the other hand, is a nuisance.
No temperature discussions: “Set the air conditioning to 18 degrees!”-“No, that’s much too cold. Better 21 degrees!” You can spare yourself such discussions by using surface cooling. Thanks to the surface cooling principle, no one is too cold and no one is too warm.
Buying a cooling system – What do you have to look out for?
Now, before you start thinking about buying and installing a cooling system, we advise you not to act too hastily. Especially for surface cooling, you should ask yourself the following questions in advance:
- Which rooms do you want to cool?
- How large are the rooms to be cooled?
- Ceiling, floor or wall cooling?
- Do you live in a new or old building?
- Do you install it yourself or do you get an installer?
- How should the pipes be laid? Conventional helical or serpentine laying? Or parallel (Tichelmann system)?
- Do you want to cool with a heat pump or with naturally cold water from the ground or basement?
Not sure if your heat pump is suitable for cooling? Worried that your old apartment can’t have a cooling system installed? Our advice: contact a professional. He works through the questions for me and explains the details of the system to you.
You want simple system that can be installed anywhere? Then you should read on. Let me briefly explain the advantages of the egger system.
The simple solution: The egger cooling system for everyone
The advantages of the egger system compared to conventional surface cooling systems:
- It is suitable for any type of building (new, old, apartment, house, hall, etc.).
- You are free to choose whether to install it in the floors, ceiling and/or walls.
- It doesn’t matter if you use a heat pump or the “natural” cold from the ground.
- You can heat with the egger system even in winter.
- Your rooms will be cooled more evenly and quickly thanks to the parallel routing of the pipes.
- You don’t need a professional to install it. You get step-by-step instructions when you buy. This way you can install the egger system in your home even without a professional installer.
