Tips for air conditioning – Best climate in the car
In midsummer, the car is heated by the sun quite strong. Whose got air conditioning, is in a clear advantage. Because you need to drive a cool head. Important tips for the use of an air conditioner in the car Jens Alinia has made the traffic editors.
Air conditioning in the car
The car is extremely heated by the sun, you should open all windows before leaving for the first time and let the hot air out of the car flow. You may turn the blower on highest setting. Only then it is advisable to put the air conditioning.

Not in the body richtenDie cooled air should never aim directly on the body and certainly not in the face. While at first this may perhaps be quite pleasant if you are coming from outside, but that is very unhealthy. Instead, we prefer to let the cold air flow through the nozzle to the front window. This is the way in the rain very practical, because the air conditioning system draws moisture from inside the vehicle and prevents the glass from fogging – a very practical side effect. Those who want to avoid the cold, should ensure that the temperature inside a maximum of five to six degrees below the outside temperature.

Longer run an air conditioner at least ten minutes should be operating at best longer. This fact the entire cooling system such as refrigerant, evaporator and refrigerant compressor is adequately lubricated. Therefore, it is better to run the air conditioner for long. Thus in addition to a possible contamination of the entire system is prevented. Even in winter you should turn the air conditioning when outside temperatures of more than three degrees plus a regular basis. Otherwise, the air conditioning system break down. That is what happened to me. I have neglected my air conditioning criminally used almost never. The result: You have been calculated from these record temperatures given up the ghost.

Fuel consumption increases in the car with air conditioning on. The a/c compressor is powered via the belt from the motor, which consumes more fuel. How much more will be sucked out of the tank depends on the temperature outside. When cool, for example, at 35 degrees of outside temperature to 20 degrees down, then this may mean in town ever up to six liters consumption per 100 kilometers. Not quite as bad as it is on the highway. Since one expects more than one and a half liters consumption per 100 kilometers. A / C off and windows open is no alternative, because at high speed and open window of the fuel consumption is also rising.

Refrigerants – Uncertainty regarding auto air conditioning
Two years ago, a new refrigerant, as the currently used is environmentally harmful. There are two new solutions already exist, but nobody knows which funds will be used now.
Some time ago, experts have recognized that the agent in car air-conditioning is environmentally harmful. So it was decided that another was needed – by the year 2011. What is in it as well – which refrigerant will continue to be found in air conditioning is not fixed yet.
Dessau / Berlin. Some time ago, experts have recognized that the agent in car air-conditioning is environmentally harmful. So it was decided that another was needed – by the year 2011.
An alternative was found quickly, even as manufacturers’ association VDA, the new solution was in order – it was said at any rate at the time in 2007. Now, however, is 2011 not far to drive but instead found the solution, everything changed. For now another alternative on the table. Although a new tool in a good year to be used, no one really knows now what will it be.
In the air-conditioning systems of cars, a refrigerant called R134a is used. This means, however, has a global warming potential that is 1,300 times as high as that of carbon dioxide (CO2). Each car comes with R134a, therefore, according to the Federal Environmental Agency (UBA) in Dessau from unavoidable leaks in the system per kilometer ride seven grams of CO2 addition. In Germany alone, 2006, about 2,300 tons came from R134a air conditioning systems of cars in the atmosphere.
European directive sets the tone
Experts was therefore long been clear that had to be made for replacement. And so it came to a European directive known as 2006/40/EC. It states that from 1 January 2011, only new passenger car models may be authorized to release their air conditioners a lot less unpleasant substances into the environment. In plain text may continue a certain amount of refrigerant in the plant more than 150 times its climate-damaging than the same amount of CO2.
The solution that was found was, at first somewhat surprising: CO2. For, while CO2 emissions in terms of the exhaust gases of a car as something is, the rate must be lowered, it has clear advantages in terms of air conditioning. What comes out of an air conditioning system in terms of environmental impact is called the global warming potential. The three letters are an abbreviation of “Global Warming Potential” and describe the risk of the product in terms of global warming: While R134a has a GWP of 1300, lies in the cold technically called CO2 R744 just at 1 Because of this, it seemed like the decision – and several producers commented on the development of appropriate car air conditioners.
Further refrigerant in an interview
Unexpectedly brought companies such as Honeywell then another refrigerant into the conversation. It is called HFO 1234yf from the perspective of manufacturers and has the advantage that it can also be used in the already existing air conditioning systems – however, needs new CO2 air conditioning systems.
There are at HFO 1234yf but also one major drawback: it is considered to be combustible, may, according to EPA to “make a fire highly corrosive hydrofluoric acid.” Although time is running until January 2011, is the bottom line but everything is open again. “The changes will come in 2011, but is still unclear which refrigerant will be used,” says Wolfgang Plehn of UBA.
The refusal decision could have consequences if it is actually far. The problem: “The industry should now already in its manufacturing facilities for the future air conditioning units,” said Gerd Lottsiepen, transport policy spokesman of the Transport Club Germany (VCD) in Berlin.
While the final decision still a ways off, for example, drops Honeywell stone unturned to make HFO-added 1234yf harmless. It is repeatedly referred to flammability of the composition, it is “10 000 times more likely that a person is struck by lightning than to be injured by a HFO 1234yf inflammation due to a crash.”
To Wolfgang Plehn it is unclear what such calculations are based on. The EPA is rather with the statement that the agent is flammable and that just may make the dangerous hydrofluoric acid. This in turn can lead to severe burns to skin and respiratory tract. “For the EPA, CO2 is an environmentally friendly alternative,” said Plehn. Which choice is the manufacturer make, must be seen.

Why is the air conditioning cooling ?

The kitchen is a versatile research laboratory. Appliances such as stove and refrigerator invite to experiments, such as the interplay between liquid and vapor: Putting on a pot with water, it starts to boil. The liquid absorbs heat and turns into steam. With the windows closed also reflect moisture condenses on the kitchen walls. It condenses and releases heat.
The transitions from liquid to vapor and vice versa is exploited in a refrigerator. Only that it unfolds here in a piping system at low temperatures and different pressures.
The main components of the refrigerator are therefore evaporator and condenser.
The evaporator produces the cold. In it evaporates at low pressure, a special liquid as a refrigerant. There is a gas, while it cut the inside of the refrigerator heat. The result: in the refrigerator’s cold.
To set in motion a cycle, a compressor sucks in these steam. He also increased the pressure of the gas. “This will compress the refrigerant, are currently the most hydrofluorocarbons,” says Lothar Oellrich, an expert in refrigeration at the Karlsruhe Institute of Technology. The molecules move closer together.
Then they reach the pipe on the back of the refrigerator. Thanks to its many turns, these fins have a large surface. They act as a capacitor. On their inner walls precipitates moisture, the steam liquefies and releases heat to the environment. Then warms up the kitchen while it is colder in the refrigerator.

“With an open refrigerator itcan be cool but not the room,” says Oellrich. To make the principle refrigerator with air conditioning, must be separated from each evaporator and condenser. “You can not both be in the same room.” The evaporator is to remove heat from the room, the capacitor is however outside. There he can deliver the heat of condensation to the outside air. be connected to an entire house has air conditioning outdoor unit that only by pipes with several rooms.

Other news in refrigeration and air conditioning:
The Danfoss Group warns of a potential fire risk for refrigerators and freezers that have been made to 1994 or acquired. These devices can be equipped with a compressor, cause its so-called starter may have a spark and cause a fire can. Danfoss offers affected owners of such equipment a free replacement starter.

The Danfoss Group is a leading manufacturer of components for the drive, refrigeration and heating equipment. Last year, the company and the Danish Institute tested for consumer safety, some refrigerator fires. They noted that the aging process of the plastic that was used for the affected starter, can create sparks. can in some cases, the dust that often collects at the back of refrigerators or freezers, ignite. The risk increases with age of the refrigerator. Particularly vulnerable are refrigeration devices that are operated infrequently, especially if they are exposed to high humidity. Identification of affected devices
The compressors of refrigerators or freezers are located on the side or rear of the unit. Danfoss compressors have a yellow label to see the company logo (see picture). Affected are devices that were manufactured in 1994 or sooner or acquired (purchased used equipment may also later) as well as devices that have the model name in the first few letters T, F, N or S. Other Danfoss compressors are not affected. The group specifies that have been used for environmental reasons, after 1993, other housing materials for starter, for which there is no spark risk.
Free replacement of the affected parts of the device
Danfoss offers owners of affected refrigerators and freezers a free replacement starter for the compressor. Consumers receive detailed information on the website of the group. There you will find pictures of the affected devices and a form with which the truck can be ordered directly from the company.
The Company believes that today only a few of the refrigerators and freezers that were manufactured in the late eighties and early nineties, in operation, because they are believed to have been largely replaced by modern, energy-efficient appliances. exchanged in order to ensure maximum safety, warns Danfoss before further use of affected devices until the fire-prone starters are.

“The hx-diagram is a fascinating and highly useful work tool.”

How do the relative and absolute humidity to the temperature? What is the latent and sensible cooling capacity, and which of them available in the data center? Why and when should humidifier be used?
These requirements have become more and more IT managers or data center manager sat apart. But some basic knowledge of air conditioning is required, especially if you will not rely 100 percent on the testimony of the product supplier and would like to. Because not every supplier is independent and objective, what is the nature of the thing.

An essential tool to help with visualization of climate processes is the hx-diagram, which was developed long ago by a Mr Mollier. If you understand the many lines and curves, even air can be easily explained technical events in the data center and next quilt also calculated.

The hx-chart visualizes the interaction between the air temperature and humidity, can hold.

The simplest derivation is certainly the reading of the following circumstances: 0 degree cold air can hold about 4 g of water per kg air (about 1.2 cubic meters), while 20 degrees air for more than 16 grams, so it can hold about 4 times the amount of water . This explains why there are severe thunderstorms in the summer with lots of rain in the winter is not.
Furthermore, we see that 15 degree warm air with relative humidity at 26 degrees 80prozentiger only 40 percent relative humidity has. And finally, is reflected in the way you add each cubic meter of air at 20 degrees and 30 percent relative humidity about 3 g water has to rise at a constant temperature the relative humidity at 50 percent.
Why do we need this information? It is about money that you wasted, when these relationships are not understood and interpreted!

Save money

Take, for example on, we have a server room air-condition with a simple split device that cools the heat exchanger to 3 degrees and the control temperature in the room is 24 degrees, 45 percent relative humidity. At this temperature continuously below the dew point and water (condensate) separated.
This effect can cost twice money as both the withdrawal of water energy costs as well as the tracking of the separated water by steam humidifier. The alleged investment deals for the cheapest air conditioner is operating to a trap.
Using a small counter-checks on the hx-diagram would have it at once and quickly calculate.
What was shown here with a relatively plastic example is, of course, for all climatic processes. You understand immediately why bring a temperature increase or other moisture window of saving energy and why the Cabinet is better than another.
Therefore I can only everyone who is responsible for air conditioning of data centers, suggest the hx-diagram to heart. It is a fascinating and extremely useful work tool.

spent quite a bit of time researching air conditioners before purchasing. We live in Oregon and it doesn’t get too hot but there’s a month or two in the summer where the heat and humidity get oppressive in the house. I wanted an inexpensive, small, window air conditioners to increase the comfort. I wanted something small enough that I can store it the other 10 months.
So, after much research I ordered this model. I was going to get the 6K BTU model with the electronic controls but I figured I would get something super cheap and if it didn’t work I could use it as a single room cooler. Shipped free which makes this a pretty good deal. Arrived in about a week.
Installation was easy, following the instructions in the manual. I did have to install and remove the air conditioners about 3 times to get all the sealing right. In the box there’s a lot of different thicknesses of foam and foam tape. There is no specific instructions about what to do with this, except the stuff for the top gap of the upper sash. So, I experimented with various combos to get a good seal. We have recent vinyl windows with screens but no storms so the unit basically dropped right in. However, there are some gaps around the bottom in this configuration. I stuffed these with the thickest foam that came with the unit. This did the trick but didn’t look too great. Luckly I ordered extra foam tape as another reviewer recommended, and I used small pieces of that to caulk around it inside and outside, leaving the big foam inside. It actually looks pretty neat and professional. $4 well spent
Anyway, the unit is installed in our main living room. We are in a 1940′s box bungalow so this room is about half of the width and length of the house. The bedrooms and kitchen connect to it. With it on HI cool/Max(7) the entire house has been very cold and huge amounts of water have been pulled out. We will see how it performs in the upcoming week of 95+ temps. We keep a few $10 box fans around to circulate air so I can move the cold air around.
One thing is that I have heard mentioned on a few other models is that the fan catches water in the pan and spits it around. This is a feature and not a bug . The unit is designed to pitch backward slightly when properly mounted. Moisture removed from the room collects at the bottom. The fan blade is coated in rubber and it’s designed to suck water up and spray it on the evaporator coils. This facilitates some precooling of the outside air. It drastically increases efficiency. I would not drill drain holes, as other people have mentioned.

Stuttgart – Worldwide, 600 million cars have air conditioning. And there are constantly more. By the year 2015, about a billion air-conditioned vehicles are the way to estimate the IPCC. Environmentalists accuse the industry to rely on outdated air-conditioning and refrigeration products and dangerous so to enhance the greenhouse effect. “Pro Air – Efficient Car air conditioning systems with natural refrigerants” – is the name of a new Europe-wide information campaign that started the German Environmental Aid Association and the Transport Club Germany.

Debate on the energy concept, the right way “to municipal utilities
show all items “The operation is funded by the EU Commission. The main objective is to educate consumers, particularly motorists on the environmental impact of facilities and enforce better air conditioning technology. Environmentalists have been fighting for years for more efficient equipment. DUH VCD and complain that the car industry to undermine the EU’s climate change law and endangering motorists with new toxic refrigerants. Using sleight of “trying the industry, the EU ban of harmful refrigerant R134a (tetrafluoroethane) to circumvent, this is true in 2011, the DUH-CEO Juergen Resch criticized yesterday in Berlin.

Environmentalists have asked the auto industry. Thus, according to Resch’s current intention is not a single manufacturer, and from next year to give new models to R134a. Instead, models were already logged for the next few years with the technology now allowed. The refrigerant 134a once replaced the dangerous and jointly responsible for the ozone layer is chlorofluorocarbons (CFCs), heat the atmosphere but after DUH details 1430-times stronger than carbon dioxide (CO2). Of the leakage, accidents and improper scrapped in 2006 alone, according to EPA about 2,300 tons of R134a came into the open. This is consistent with the extremely high output of three million tonnes of CO2 and thus the climate impact of 1.7 million small cars to drive the 15 000 kilometers, expected before the environmentalists.

The industry makes a bicycle kick

Resch is especially the President of the Association of the Automotive Industry (VDA), Matthias Wissmann, disappointed. Wissmann had promised after taking office, the replacement of the existing air conditioning technology, criticized Resch. Accordingly, should air conditioning systems in new vehicles will be working with the natural, unproblematic refrigerant CO2 produced in large quantities as waste material as in energy production in power plants. This promise was “broken, like many other climate change and fuel excise promise” the auto industry but.

The stated reason for rejection of the interim CO2 Technology suspect environmentalists higher conversion costs for the automakers and the influence of the chemical industry. Manufacturers like BMW, which had forged ahead in CO2 air conditioning systems, made according to Resch backed down, because each vehicle would be created initially costs of about € 50. For the CO2-pressure compressors and other equipment more lines are needed. In addition, the chemical industry to penetrate an artificial substitute for R134a, which have brought the industry billions in sales. The substitute 1234yf, patented the left and the two chemical giants would use the automotive industry continue to cool it, there is less harmful to the climate, but expensive and in case of fire are highly toxic to criticize VCD and DUH. “We go from bad to worse,” complains Resch.

Environmentalists complain also that a great many cars are traveling with outdated, non-controlled air conditioning. Their fuel consumption was up to 2.5 times as high as in modern systems. But the replacement of the old plant could relieve the world’s climate 40 million tonnes of CO2 per year. The auto industry has rejected the criticisms of environmentalists. The new refrigerant 1234yf was safe, the use of safe, a spokesman said on request. Therefore we have chosen. You also need a “global standard and not an island solution”, said the association

Bock Training Centre in Frickenhausen
(Business Wire) Frickenhausen, 05.11.2010, with a novel training approach and the cooperation partners Danfoss and Knudsen Koling Bock offers hands-on workshops around the carbondioxid CO2 system engineering.

An environmental awareness has now spread across industries and in
numerous markets in importance. In many application fields of refrigeration and air conditioning to natural refrigerants and have prevailed among them in particular CO2.

For this reason, Bock has been providing mid-May 2010, with the cooperation partners Danfoss and Knudsen Koling Seminars, which can gather interested professionals theoretical knowledge and practical experience with CO2. The offer is aimed at plant engineers and planners.

Practical training on topics related to the compressor are since 2007 in its own stand-
Training center at the headquarters of the company offered. Around 1,000 people visit each year since to Frickenhausen there to enhance their mechanical and electrical engineering skills and compressor technology to practical experience.

The growing interest in the subject area of CO2 and the resulting demand for skilled technical personnel it was decided to buck, also offer special workshops covering all aspects of systems engineering include CO2. Because sometimes it is missing in most companies often of practical experience. The workshop was therefore a fully functional CO2 supermarket is built booster system equipped with the latest controls technology, refrigerated equipment for refrigeration and freezing and sub-and transcritical compressors.
Through the cooperation with Danfoss and Knudsen Koling flowed the experience of all three companies, not just in the new facility one, but is also reflected in the wide-ranging training content.

That CO2, especially in Europe’s most promising natural refrigerant and already often heard in use has its reasons. CO2 is not only environmentally sustainable as a refrigerant for supermarket systems. Also on security for the handling of the much higher system pressures, it is superior to many other solutions. Moreover, in Europe there are a relatively high number of skilled technical personnel and the moderate climate provides ideal conditions for CO2.
However, natural refrigerants are not only in Germany on the rise, they have attracted great interest among experts from all over the world. Likewise, natural refrigerants not only stood at the Mostra Convegno and this year Chillventa center stage, but were also the main topic at the Gustav Lorentzen Conference and the simultaneously held ARBS in Sydney, Australia.

Back in 2006, Bock presented the various compression solutions for stationary use of CO2 on the IKK and since then has steadily gain new experiences with CO2 systems and improve it. The partners Knudsen Koling and Danfoss look back on years of experience, the taxing to the success of CO2 training courses.

The focus of this training is the compressor, but just because the need for know-how in other areas is relatively high, all the important topics around the CO2 system technology.

The first courses have shown that the issue of CO2 is based on broad resonance and at the same time there is a great need for information. Especially in the handling of CO2 is still a large uncertainty felt by the practical “hands-on experience so important to make. Fact, the company during the first event, most of the questions the student on the handling of refrigerant CO2, differences to conventional refrigerants, installation and the components with higher pressure levels.

The conclusion of the bracket product manager for CO2 Manuel Fröschle is after the first successfully completing the training, therefore: can “To the participants of the training we see that just in terms of CO2, a high information need and we have followed the decision for the workshops in the right direction “.
