Design of a trigeneration system for a hospital complex in Gran Canaria

Abstract

This article presents the design of a trigeneration system for a hospital complex in the city of Las Palmas de Gran Canaria (Canary Islands, Spain). The absorption refrigeration machine uses water as cooling fluid and lithium bromide as absorber. The energetic analysis shows high values of thermal performance and of electrical equivalent performance. The percentage of primary energy saving is about 23 %. The economic justification is realized taking into account the cost of the initial investment, the operating costs and the income forecast, turning out to be a profitable investment.
