New refrigeration technologies are not yet widely available, but these innovative technologies have paved the way for the future.
Editor’s note: Air conditioners account for 10% of global electricity consumption, and the earth’s temperature is getting higher and higher. What should I do? Develop more advanced refrigeration technology! It is easy to say that it is easy. Fortunately, many companies are working hard to let us know about the latest refrigeration technology!
Alarm: Earth temperature is rising! So humans need more advanced cooling technology.
The International Energy Agency released a report in 2018 that the energy consumed by space cooling will increase by more than two times by 2050. Air conditioners consume 10% of the world’s electricity consumption. The interior of the air conditioner has a HFC refrigerant that turns into a stronger greenhouse gas than carbon dioxide.
Shelie Miller, environmental program director and environmental engineer at the University of Michigan, said: “This is a vicious circle. The earth is getting hotter and hotter. We turn on the air conditioner and consume more energy. The more energy we consume, the more greenhouse gases are released. More, the result is that the earth is hotter.”
How can I solve this problem? Scientists and engineers are working hard to develop more complex and energy-efficient cooling technologies.
Miller said: “Improving HVAC (heating, ventilation and air conditioning systems) technology can improve cooling efficiency, and can also switch to renewable energy, which can reduce greenhouse gas emissions. Look at human history, once we used innovative methods to give The building is cooling down and there is no air conditioning with very high energy consumption.”
Speaking of the concept of air conditioning, it can be traced back centuries. The ancient Persian engineers developed the “badgirs”, which was designed to suck cold air into the room, and “yakhchāls”, which can make ice, the equivalent of the earliest refrigerator in the desert.
In 1820, Michael Faraday discovered that the ammonia was compressed and then released, which cooled the air. In 1902, engineer Willis Carrier designed a device for the New York-based Sackett & Wilhelms Lithographing and Printing Company. He passed the circulating air through the coil and cooled it with ammonia, so that the humidity could be controlled when the color printing task was completed. In the end, his design became the world’s first electric air conditioner. In 1925, he was put into the Rivoli Theatre in Times Square. Even in the summer, the audience can watch the blockbuster here.
