CISNEROS RAMIREZ, César A. Feasibility of the use of solar cooling of small capacity. Energética [online]. 2014, vol.35, n.2, pp. 92-100. ISSN 1815-5901.

This work presents an economical evaluation of implementing a solar air-conditioning system using solar energy in Havana, Cuba. It was studied the feasibility of systems of small and medium capacities (7-35 kW) of absorption refrigeration machines which be in the world market. The parameters that were taken for the feasibility were the payback time and life cycle savings. Also it was analyzed the influence of the ratio storage volume/solar collector area (V/A) on solar fraction, auxiliary energy, saved energy cost, saved primary energy and emitted CO₂. Besides, it was used the P₁-P₂ method for the economical aspects and the Φ-fchart method in order to determine de solar fraction. The price of petroleum was varied from 100 to 200$/barrel.

Palabras clave : absorption; economic analysis; solar cooling.
