| description | This paper analyses the performance of a NH3–H2O absorption machine powered with a linear Fresnel reflector. , The various components of the absorption machine and the linear Fresnel reflector were dimensioned for a power of 10 kW. A numerical model combining Monte Carlo ray tracing and Computational Fluid Dynamics was developed to evaluate the outlet temperature of the linear Fresnel reflector. The outlet temperature is used as input data for the simulation of the thermodynamic model of the NH3–H2O absorption machine using the commercial software Engineering Equation Solver. The results showed that the linear Fresnel reflector consists of 30 reflectors with a length of 10 m and a wide of 0.2 m each, 5 absorber tubes with a height of 4 m each and 1 trapezoidal cavity with a length of 10 m and a height of 4.065 m. A hot source temperature of 169.24 °C was recorded when the coefficient of performance reaches 0.510. |
