Simulation and Economic Analysis of Parabolic Trough Solar Assisted Single Effect Absorption Chiller for Famagusta, Cyprus

This research contemplates on the valuable utilization of solar based energy intended for a restricted region in the Mediterranean basin. Especially in Mediterranean section with high solar gains and high cooling demands, solar cooling will become more and more an alternative to established cooling systems. Solar energy turns out to be progressively well-known and the accessible solar oriented market is explored with the point of selecting and evaluating a pilot locale for a promising solar based application. The system is displayed and assessed in details for the authentic related analysis application. The goal of this study is to access the traces of using underground water temperature instead of the inlet temperature of condenser on the energy outputs of the generator, the condenser and the evaporator, moreover, to investigate the feasibility of a solar single lithium bromide-water absorption cooling system for Famagusta, Cyprus. The system has been intended to supply cooling loads of the office building area of approximately 200 m² for working hours from 9 am to 16 pm, 5 days a week, in all hot weather states of Famagusta. TRNSYS software program has been used to estimate the performance of the system throughout the summer season. The performance calculations indicate that:  A 35kW absorption chiller is sufficient to appropriate the 200 m2 office space cooling requirements,  Use of 30 m2 parabolic trough collectors will be sufficient to operate the absorption chiller,  22℃ underground water is better to use in condenser and absorber instead of cooling tower water, which is commonly used in industries that provides a minimum sink temperature of 32℃,  COP of the system is obtained as 0.672 for 22℃ of the condenser inlet temperature of underground water.
