Direct Fired Chiller
Providing cooling with double energy efficiency
after avoiding energy loss from the 5 energy conversions

The technology of providing cooling from fuel is invented by BROAD. It has broken the monopoly of providing coolingfrom electricity and has been sold all over the world in just a few years. Why? Because we've digested the second law of thermodynamics: with each energy conversion, there is always energy loss. We understand electric aircons require five energy conversions to produce the cool air. They are fuel → thermal energy → mechanical energy → electric energy → mechanical energy → cold air. While BROAD directly provides cooling in one energy conversion, the energy efficiency is undoubtedly doubled. What's more, the separate heating technology invented by BROAD combines cooling, heating and hot water in one chiller, successfully eliminating the threat of boiler explosion.
