The system was developed by two students from Ben-Gurion-Bengev University who won an award from the Association of Electrical Engineers in Israel. It is an autonomous and modular system that activates itself when a person enters the room and adjusts according to his position. The system works without the need to use a remote control or batteries
Two students from the Department of Electrical and Computer Engineering at Ben-Gurion University of the Negev, Idan Admon and Yaara Ben-Or, under the guidance of Prof. Raul Rabinowitz, who developed "air conditioning systems based on temperature control and human position" as part of a final project of the degree, won a prize in the competitionA. At the central conference of the Association of Electrical Engineers in Israel, which was recently held in Eilat.
Students from the Department of Electrical and Computer Engineering at Ben-Gurion University of the Negev, developed a system that interfaces with the home air conditioner and is based on real-time temperature control and human location. The autonomous and modular system that was developed is designed to improve the quality of life and at the same time save the energy that is wasted in normal operation of the home air conditioner.
The system pushes aside the old technology of remote controls and batteries and works with real-time detectors, thus allowing the person in the room to continue their activities despite the severe heat or cold, and this is due to the system's ability to operate autonomously when a person enters the room, turn off when he leaves, and perform real-time monitoring for the duration of the stay in the room.
The system makes use of an infrared detector and a depth camera in real time, allowing the construction of a system based on location data, which knows how to map the space of the room into areas of work. This way you can get controlled, smart and economical control that focuses individually on each person in the space of the room, in a modular way, depending on their location in real time and the climate of the room. Using an infrared sensor, even allows the identification and locating of several different bodies in the space of the room in total darkness.
In addition, the system samples the room temperature at any given moment and, when necessary, immediately controls the room climate.
The developed product is a prototype that is expected to find widespread use in the industry, due to its low cost, its ability to direct the efficiency of the air conditioner and thus save wasted energy, and its compatibility with the smart home model.
The conference of the Association of Electrical and Electronics Engineers in Israel unites all areas of energy and renewal in the fields of electricity in Israel.
The competition focused on an outstanding project in the entire field of electricity and renewable energy, during which the competitors were required to submit a content project book to investors and deliver a marketing presentation in English.
"We invite you to be impressed and move forward to a human air conditioner with personal attention and enjoy complete freedom without a remote control," say the two proud developers.

And what if there are 2 or 3 people in the room and each is in a different location?
Agree with nachum37. Imagine what happens when someone enters a small room, such as a bathroom, a dimension, a small study. What happens when there is a baby in the room? The temperature changes made by an air conditioner are significantly slower in relation to the volatility of the person in the room. What's more, no one wants a different temperature (men want to be colder, women less cold, children don't always pay attention to the level of cold and babies are extremely sensitive to it. So when five people of different weights, with different detectors and with different needs move in the same room, the system will not be able to withstand in its unique requirements and at the end of the process those household members will return to the default temperature for each room.
Bad solution.
No one likes a direct air stream, a gentle distribution for a uniform temperature is better.
In addition, you will have to program the system for a gentle transition between openings when a person moves in the room, and in case a person moves quickly it will be ineffective because every time the air conditioner will have to work again to cool the area. It is only effective for a large living room.
