The British Guardian published a prospect article on the 2022 Cartel World Cup. The article believes that the summer temperature is very high Qatar, the World Cup will be its development of innovative air conditioning and refrigeration technology a good opportunity.
The World Cup is in full swing. The temperature on the pitch has reached a record 38.8 ° C. Does this make the habit of the tropical climate team get an unfair advantage? In order to make the game more equitable, one of the ways is to install air conditioning on the football stadium.
The idea sounds crazy, but Qatar official has said that this is what they want to host the 2022 World Cup when the approach taken. Qatar's temperature is often more than 45 during the day, and such measures are absolutely necessary.
The first question to do so is that the organizers must pass an investigation of corruption in the FIFA Ethics Committee. However, the bigger difficulty is how to use solar and renewable energy, because Qatar has made this commitment. This will be a huge challenge, but it makes sense. With the rise in global temperatures, to the next century, the temperature of some areas of the earth will become unbearable, the future demand for air conditioners will be growing.
In the absence of air conditioning on the car, the driver can open the window to reduce the temperature inside the car. However, opening the window will increase the air resistance, so that the efficiency of the car becomes low. If there is air conditioning, the driver in the hot days do not have to open the window, so you can save fuel. Everybody thinks so. However, the air conditioner itself also needs to consume energy. The latest experiments show that, in terms of energy conservation, opening windows is more cost-effective than opening air conditioners.
Nevertheless, if you encounter a big hot day traffic jam, this time to save fuel and protect the environment will be the second priority, close the windows, open air conditioning is often the only option. This is also the Qatar large-scale open-air football field facing the problem. If they install a large air conditioning system, they will need to close the roof, which will have several adverse consequences.
Traditional air conditioning works roughly the same as the refrigerator. The low boiling liquid (refrigerant) is pumped into a set of brass tubes. When the warm air passes near the copper pipe, the temperature of the refrigerant in the copper tube rises and evaporates, thereby reducing the temperature of the air. Then, these evaporated refrigerants will be squeezed into the liquid in the pump, the process will consume energy, the heat generated by the back of the refrigerator distributed out.
The heat generated by the air conditioner will be distributed to the atmosphere, which will increase the air temperature. In densely populated cities, this temperature rise will have a big impact. Scientists at Arizona State University have found that in the summer, urban air conditioning will cause nighttime temperatures to rise by more than 1 degree. This does not sound like a serious one, but in fact the global temperature has only risen by 1 degree over the past 100 years. Similarly, if the traditional way to power, Qatar's urban air conditioning will consume a lot of electricity, but also lead to air temperature rise. This is a serious challenge.
A better approach is to develop new air-conditioning refrigeration methods, such as cooling by sea water evaporation, refrigeration through a computer-controlled awning, or the use of a typhoon tower to produce convective cooling effects - a common approach to residential areas in desert areas. Qatar belongs to the desert area, and its open-air soccer field certainly does not have to be built like a football field in the tropical rainforest area of Brazil. Maybe Qatar's soccer field should be built inside the rock, so it will be cooler in the summer. Or they should be inspired by the camel's nose: the camel's nose has a layer of heat exchange effect of the membrane, it can extract water from the exhaled air, in order to cool the head.
At present, no one knows what the final solution to this problem is, including Qatar's 2022 World Cup Organizing Committee. There are many people called to put the game time in the winter, so the stadium will not be so hot. If this proposal is adopted, Qatar may miss a chance.
Sustainable, low-power cooling technology is urgently needed in today's world. As the world continues to warm, the number of cities in the desert will also increase, the demand for air conditioning technology will certainly rise. We need more clever air conditioning and refrigeration technology, 2022 World Cup for this exploration provides a good opportunity. This kind of exploration should lead to global competition; first, we should let our football players come in because they have great wealth and influence.
