According to the report of International Energy Agency IEA, there are 1.6 B AC in 2018 all over the world and this will increase to 5.6 B by 2050. As conventional AC systems draw a large amount of power and have carbon emissions due to the cooling gas, it will cause an increase in temperatures globally. The temperature increase is causing disturbances in the ecosystem of the planet Earth, so this can destroy the environment. What will be the future of the planet in this situation? Will it become difficult to live here? whether we become all dead due to high temperatures? Wait don't worry! SUSTAC has developed an air conditioning system for room cooling that consumes only 1/5thof power used by conventional AC Systems. The system will have no cooling gas involved so no carbon emissions. And probably it will be very light for the checkbooks and pockets of the customers.
