The air conditioning is a real treat in the office during a
great heat. But what is their structure and function? Devices in the form of
ceiling cassettes and also wall devices are presented.
AIR CONDITIONING: FIRST-CLASS ROOM AIR AS A DESTINATION
It's not just about cooling. Anyone who uses an air
conditioner, whether as a wall or ceiling units, can also produce a pleasant
quality of indoor air. Incidentally, this not only affects the temperature, but
also moisture, CO2 content and the general purity of the air free of
pollutants.
The ultimate goal and reason for the acquisition is, of
course, to regulate heat. So that people feel well even in outside air
temperatures of over 30 degrees. A possible failure of the system is then
always a big nuisance. Whether in cars, offices or private homes.
High-quality solutions in terms of climate and indoor air
are available at many different providers.
If you are interested, after a short search you will find
the right system for a healthy air and a comfortable indoor climate. These can
be single rooms or a large 5 room apartment.
REFRIGERANT IS THE HEART OF AIR CONDITIONING
How does a device work and how does the cooling effect come
about? Short answer: Without coolant it does not work.
• But for
the agent to develop its cooling effect, it is first sent through a cycle. This
contains a low pressure chamber and a high pressure chamber.
• A
compressor still sucks in the refrigerant in a gaseous state and compresses it.
As a result, the agent heats up and any heat generated is directed outside.
Now, a condenser liquefies the substance and supplies it to an expansion valve.
• Cold air
reaches evaporators and cools the rooms down
• Now
begins the crucial phase: The transition from the high pressure chamber to the
low pressure chamber. The gas expands and cools down in a row. It is now very
cold and reaches an evaporator.
• The air
conditioner now sucks in warm air in the offices and apartments and leads them
past the cold evaporator. As a result, the temperatures of the rooms sink to
manageable levels. A process that can be done in ceiling cassettes or even on
wall units.
Air conditioning as ceiling cassettes or wall appliances?
Overview of high-quality systems
• Depending
on your wishes and requirements, air conditioning systems can be hung in the
form of ceiling cassettes, for example, in suspended ceilings. These have the
advantage of a better appearance, because the actual lines run between the
visible ceiling and the actual ceiling.
• These
variants of an air conditioner are usually very powerful. Ideal for cooling
server rooms. They are less suitable for use in homes or offices.
PERFECT FOR HOME: WALL APPLIANCES
Alternatively, wall-mounted units are possible: Especially
the so-called split units are popular because they have indoor units and
outdoor units. Connected by hoses and pipes, they are also pretty quiet.
The compressor is installed on the outside, while in the
inner part of the air is transported and cooled. Due to their compact size,
wall-mounted units are often used in private households. These are quickly
installed and comparatively inexpensive.
AIR CONDITIONING: LATEST APPLIANCES REDUCE TEMPERATURE AND HUMIDITY
Little tip: research is almost always worthwhile.
Who wants high-quality equipment for a better indoor
climate, is spoiled for choice. Depending on the size of the apartments, it is
possible to effectively reduce the temperatures of the rooms and at the same
time ensure better air humidity and cleaned room air. Specifically, they absorb
heat of evaporation in midsummer and thus ensure a drier, pleasant air.
This is because air conditioners of the latest design: it is
not simply lowered the temperature in the living rooms. Rather, the additional
lowering of moisture for an improved lifestyle. The humidity decreases and the
person recovers from the strain. And that should first be target number one,
who is interested as a customer for air conditioning.
ADVANTAGES AND DISADVANTAGES OF AIR CONDITIONERS
It is midsummer. The heat is unbearable. Everyone now knows
the beneficial effects just described that air conditioning can generate.
Office staff, for example, can work efficiently even at high outside
temperatures without having to worry about circulatory problems.
Positive consequence: Their performance increases. The
effect is even stronger, even though the humidity levels on innovative air
conditioning units are falling to a healthy level. Incidentally, the ideal indoor
temperature is 22 degrees and the optimum humidity is 50 percent.
NEGATIVE CONSEQUENCES IN THE USE OF AIR CONDITIONERS
If the system is not regularly checked, pollutants can be
released into the air. These can be, for example, microorganisms that often lead
to respiratory diseases in sensitive people after inhalation. For small rooms,
however, it is sufficient to have a check carried out over an interval of two
or three years.
HIGH ENERGY COSTS AND POSSIBLE ECOLOGICAL DAMAGE
In addition, there is a relatively high energy consumption,
the generation of waste heat and in many older devices a high volume in
operation. In addition, many users tend to set their air conditioners too cold.
At the same time, they promote colds for themselves and their relatives as soon
as the difference between warm air and cool air outside appears too great.
WHAT IS A USEFUL REFRIGERANT FOR AIR CONDITIONERS?
Negative consequences can be caused by air conditioners if
the wrong means of cooling is used. Formerly was CFC (chlorofluorocarbon),
which was banned because of its damage to the ozone layer from 1987.
Today, inter alia, HFCs (fluorocarbons) are used, which,
while not endangering the ozone layer, are again considered to harm the
climate. Although propane or butane, so-called non-halogenated (chlorinated or
fluorinated) hydrocarbons are not harmful to the environment, they can be
explosive in high concentrations.
CARBON DIOXIDE AND ITS BENEFITS
There is a solution: carbon dioxide. The amounts required
for refrigeration units or heat pumps are quite low. In addition, only such
carbon dioxide is used, which would get into the atmosphere anyway. In
addition, it is not flammable and therefore more convincing in terms of safety
than other means of cooling.
TIPS FOR CHEAP AND ENVIRONMENTALLY FRIENDLY USE
Save costs and protect the environment. There are ways to
use air conditioning intelligently. The negative aspects can be reduced in this
way. That's how users make it right.
CLEVER USE OF AIR CONDITIONERS
Use efficiency class A when purchasing. The device only for
pre-cooling, but not constantly use. Never set too cold. During the day, keep
the window closed in hot weather and when operating the air conditioning. Open
this at night and use the natural coolness.
ARE AIR CONDITIONERS WORTHWHILE?
Institutes such as Stiftung Warentest (7/2018) are in
agreement: the best results are achieved by the so-called split devices. So
plants where indoor units and outdoor units are used as a component and where a
refrigerant circulates in between. This principle ensures rapid cooling with
relatively low electricity costs.
Problem: Only installers and specialist companies for air
conditioning and refrigeration are allowed to install these systems.
Accordingly, customers have to wait to install these efficient systems at home.
MONOBLOC AIR CONDITIONERS AS SECOND BEST SOLUTION
Another solution is so-called compact or monoblock air
conditioning systems. These are mobile air conditioning systems that do not
need to be installed. Installed on the tilted window, they lead the warm indoor
air outside with the help of a hose. As the warm air flows back into the rooms
through the open window, the system runs in continuous operation.
The result: high costs in operation. In addition, the
devices are quite loud, which can disturb potential neighbors. At most a second
best solution, who wants to cool his apartment in the heat. Those who choose
these non-stationary devices to survive the summer heat should not have direct
neighbors who may feel disturbed.
Of course, mobile refrigerators are mounted quickly and the
coolant has been filled in the rule. Whether such a device for cooling the
rooms comes into consideration, you can find out, for example, when visiting a
hardware store.
LIVE IN SUMMER WITHOUT COOLING: TIPS ON HOW TO "SURVIVE"
There are two to three months a year in Germany, where it
can be unbearably hot. If you do not mind the heat too much, you should at
least keep the following tips in mind so that the apartment does not overheat
and the outside air stays outside. At least one possible failure of the system
is then no longer an issue.
Properly airing is always the most important recommendation:
best in the morning until 10 o'clock or at night. In contrast, when the sun
bounces off the sky during the day, the windows must remain closed and darkened
with blinds, shutters (even better: shutters). Awnings can also provide
protection from direct sunlight.
If you throw in a small fan to let the air circulate, it
will reduce the temperature in the apartment a bit. Of course, the result is
not as effective as state-of-the-art wall units with split operation and
components or climate systems with ceiling cassettes.
CONCLUSION
The summers are (felt) constantly hotter and the purchase of
air conditioning is an increasingly important topic for more and more people.
If you really want to cool your rooms, you should think about what kind of
cooling system you need. These can be wall-mounted units with split operation
or systems in the form of ceiling cassettes that are optically almost invisibly
installed in the ceiling.
A refrigerant is indispensable in the cases presented, but
ecologically not always the sensible solution, as used substances such as HFCs
or carbon dioxide are considered harmful to the environment. If you are tough
and can tolerate heat better, it darkens your rooms and simply uses fans.
