The air conditioning technologies we have been working on in the past few years are closely allied with our research on transition of heat across thermoelectric materials. Having dedicated a lot of time on studying the processes of conversion of thermal energy into electricity we came up with the idea of building a device that would utilize generated heat as a source of potential energy for generation of electricity. And across all appliences a standard air conditioner is one of the most inefficient devices in terms of energy saving which we decided to implement this solution to. A typical household air conditioner generates approximately 5-6kW of thermal energy for every 1kW of electricity consumed, which is generally desposed off as a hot air through an outdoor unit. This hot air, however, is an excellent source of potential energy as its heat having a relatively high temperature difference with outside air can be converted into electricity that can be supplied back to the air conditioner and reduce energy consumption from the grid. Conversion of that heat into electricity would happen by means of thermoelectric generators, another project from our poftfolio of technologies. So combining the traditional technology of air conditioner with our thermoelectric generator technology we build our Hybrid Air Conditioner (HAC).

Unlike the Magnetic Generator and Centrifugal Boiler, the technologies behind the HAC are much simpler in design and already known and used worldwide. The advantage of our HAC technology is explained by a better solution in engineering and design that significantly reduces energy consumption needed for separation of hot and cold mediums and generation of cold indoor air. The key feature is associated with the transition of hot air from the external unit to the cells of thermoelectric generators with minimum heat loses at every stage of the transfer. In order to achieve the highest temperature difference between the hot and cold side of the thermoelectric plate , the thermoelements are placed in a calculated sequence on metal plates so the air passing through them would transmit the highest volume of energy for the generation of electric current. In the conventional thermoelectric generators, or so called Peltier elements, transformation of thermal energy into electricity rarely exceeds 15-20% excluding heat losses, our thermoelectric generators contain a special layer Samarium alloy that contributes to a better heat disposition and increases heat transfer properties increasing the efficiency of up to 65% in ideal circumstances. Our research findings suggest that combination of Samarium based thermoelectric elements with our engineering solution of transfering heat through the thermoelectric generators can increase the energy efficiency of the HAC to up to 75-90%, meaning that it can consume up to 10 times less energy than a standard air conditioner, but providing same amount of cool indoor air.

Just like generation of heat is extremely crucial in cold countries in winter, cooling and refrigeration technologies are highly demanded across all continents, and especially, in African and Asian countries. But considering how inconsistent and unreliable electricity generation is in most developing countries and how expensive electricity bills are for the majority of population, the implementation of the HAC technology in those regions promises a great commercial success and rapid market penetration. And considering that composition of the HAC is relatively standardized and manufacturing process is simple, local manufacturing can be established through a production license. That is why we believe that this project can be especially lucrative for businesses involved in the energy saving industry from developing countries.

In comparison to the progress we made with our other technologies, our work on the HAC is still in the early prototype stage as most work has been done to test electrical energy generation properties using standard setups of a modern air conditioner. With the findings we got, the next step would be to build a standalone prototype combining indoor and outdoor units into one device disposing of heat by the means of heat exchange with a separate substance. This will require approximately 6 months for additional R&D work that we plan to focus on once the work on our priority projects is complete and if there is a advantageous investment proposal made.
