This paper introduces a novel double chamber rotary sleeve compressor (DCRSC) concept. The compression mechanism is basically that of a rotary motion whereby the novelty lies in the usage of a rotating sleeves and a non-sliding vane that has one end fixed to a rotor and the other fixed end to an outer rotating sleeve. The main goal of this paper is to describe the compression processes of air as the working fluid and reveals the variations of pressure, temperature, mass and compression power inside the compressor working chambers at different rotational speed. Friction and leakage model of the proposed compressor are evaluated in Part II and Part III of this paper series. The compressor was theoretically analysed based on three thermodynamic compression approaches namely: adiabatic, polytropic and isothermal approaches. According to the thermodynamic simulation, a 171 cm3.rev−1 DCRSC can deliver a 15.4 m3.h−1 of compressed air at 9.3 bar, 6.8 bar and 4.9 bar when air undergoes adiabatic, polytropic and isothermal compression processes, respectively. The DCRSC compression mechanism shows a potential capabilities of a new compressor concept and to be well suited for the air conditioning and compressed air systems articles must contain an abstract.
