This invention relates to a process for Heating, Ventilating and Air Conditioning (HVAC) applications. In particular, this invention relates to a method for supplying oxygen concentrated air to an indoor air environment, which is termed as High Level Oxygen Air Conditioning (HLOAC): The High Level Oxygen Air Conditioning (HLOAC) primarily comprises three steps: (1). Introducing air stream to an oxygen and nitrogen separation device; (2). Separating nitrogen and oxygen in air to obtain a concentrated oxygen stream; (3). Introducing said concentrated oxygen stream into the indoor environment.
