DIAZ TORRES, Yamile; VALDIVIA NODAL, Yarelis; MONTEAGUDO YANES, José Pedro  y  MIRANDA TORRES, Yudit. Feasibility evaluation of two solar cooling systems applied to a cuban hotel. Comparative analysis. Energética [online]. 2016, vol.37, n.1, pp.35-44. ISSN 1815-5901.

ABSTRACT The article presents an analysis of technical and economic feasibility of using two configurations of solar cooling in a Cuban hotel. HVAC hybrid schemes are: a cooler of ice water vapor compression (chiller) interconnected in parallel with a smaller capacity chiller, first with a solar-powered absorption cooling system (SACS), and then with a photovoltaic cooling system(PSC). Both were simulated taking into account the weather conditions in the region, thermodynamic calculation methodologies and principles that govern these technologies. The results show that the use of these alternatives contributes to reducing energy consumption and the environmental impact of heating, ventilation and air conditioning systems (HVAC). Economic analysis highlights that PCS is more favorable than the SACS taking into account the cooling cost generation (CCG) but energy assessment indicates that SACS has higher thermal performance for the case study to which it is applied.

Palabras clave : chiller; feasibility analysis; photovoltaic cooling system; solar-powered absorption cooling system.
