The invention of a technology that converts fluctuations in humidity into energy for heating and air conditioning

Heating and air conditioning are among the sectors that consume the most energy worldwide. Around 65% of building energy is dedicated to him, while the latter correspond 30% of global energy consumption. In addition, energy prices have risen steadily in recent years. A new Israeli-origin startup called ThermoTerra has invented a technology that could solve energy cost problems heating and air conditioning. A technology that uses humidity fluctuations to heat and cool buildings. ThermoTerra believes its technology could cut energy costs in half.

The principle of ThermoTerra technology

ThermoTerra’s innovation is a temperature management system that harnesses the energy of humidity fluctuations. According to the company’s founder and CEO, Dror ZchoriThere are Transmission of a large amount of energy when water vapor in the air is absorbed by an absorbent material. When water is absorbed or condenses on a material, heat is generated. Conversely, when it evaporates, it cools. In the ThermoTerra system Warm air is stored Internal insulation of the building wall when it is hot. Insulation can consist of hempcrete, silica gel or wood shavings, all of which are known to absorb moisture well. As the air evaporates, energy is absorbed and the house is cooled. At low temperatures, cold moist air is supplied, the absorption of which warms the air and the house.

How the invention works

Sensors built into the walls monitor the operation of the system. Intelligent algorithms automatically adjust the temperature of the released air. Algorithms can also act based on external weather forecasts. After Zchori, the system can pre-store water when the weather forecast predicts temperatures to drop, even if it is very hot at “time t”. The structures to circulate the air are integrated into new walls or attached to the walls of existing buildings. These structures add a few centimeters to the wall thickness, but have a significant economic and environmental impact. Incorporating the invention into buildings would potentially reduce this by half or even zero heating costs and cooling.

The structure of the ThermoTerra technology

The invention of Zchori consists of three different elements. First the reservoir and a absorption material Special. It is integrated into the wall with air ducts that can handle maximum airflow. Then there is the system of fans, ducts and dampers. The last component is the ActiveMemBrain, which contains several intelligent sensors internet of things, a controller, algorithms and cloud computing. According to Zchori, for a private house of 100 m² it would take about $3,400 for using the heating and cooling system with fluctuating humidity. The service also includes smoke and gas leak detection.

Filtering and Monitoring indoor air pollution are also insured. For the construction of the insulation, the company is currently looking for employees to take over this part of the project. For the future, Zchori hopes to adapt its ThermoTerra technology to cool cars. In any case, heating and cooling are essential for a large number of people and the system developed by ThermoTerra can help to design houses and apartments possibly also cars, self-cooling and self-heating.
