This paper covers a thermodynamic simulation of a vapor compression cycle to generate drinkable water from the surrounding humid air. The VCC produces water by condensing water vapor along the outer surface of the evaporator as a result of heat transfer between the working fluid R-1234ze and the ambient air. The main goal of the simulation was to find suitable pressure, temperature, and enthalpy state points suitable to produce 500cc/hr of drinkable water and system parameters such as the energy consumed by the compressor and the cooling factor of the evaporator. Additionally, a parametric study was completed to examine how the mass flow rate, overall heat transfer coefficients and the amount of water yielded affect the coefficient of performance.
