New findings accelerate development of personal air conditioning

Global warming is forcing new technologies to reduce their negative impact on the environment. In this logic, scholars from Federal Polytechnic School of Lausanne (EPFL) research that will serve as the basis for new air conditioning systems. According to experts, the development of this New technology will not be possible immediately.

To better understand the differences in the perception of ambient temperature in men, the researchers conducted Measurements under real conditions. Thanks to the data collected, they plan to develop air conditioners capable of this Change the temperature of a certain space.

Dolana Kovalij, an assistant professor in the School of Architecture, Civil and Environmental Engineering (ENAC) at EPFL to participate in the research. The search results are published in Obesity Magazine.

Individual energy expenditure varies widely

In their study, the researchers adopted a multidisciplinary approach, combining applied engineering know-how with knowledge of human physiology. During the experiments, they noticed that traditional air conditioning systems do not take into account Differences in temperature perception in each individual.

In fact, according to scientists, men all experience ambient temperature completely differently. factors like Age and gender affect metabolism, which can fluctuate with diet, season, and circadian rhythm. Furthermore, to confirm their theory, the researchers analyzed the energy expenditure of six individuals who could share the same office space.

Experimental results confirmed that there are indeed significant differences between individuals, including between Two men of the same building.

“The average office temperature is 21 oh c in winter. At this temperature, some people are warm and some are cold. Our goal is to make sure everyone feels comfortable, without exception. »

Intelligent air conditioning systems can be developed

Accurate measurement of an individual’s energy expenditure opens the way for this a new technology of heating. Thus, the latest air conditioning systems will be able to process data related to individual energy expenditure To set the temperature in A specific area in real time.

This approach will replace heated chairs with limited temperature settings. Moreover, this approach can also Optimize energy consumption.

“We are working on sensors that integrate new, more complex algorithms capable of accurately measuring individual energy expenditure to better adapt the ambient temperature.”
