MONTERO LAURENCIO, Reineris; LEGRA LOBAINA, Arístides Alejandro  e  HECHAVARRIA HERNANDEZ, Jesús Rafael. Operational optimization of centralized air conditioned hydraulic networks in hotels. riha [online]. 2016, vol.37, n.2, pp.3-17. ISSN 1680-0338.

A CAD application modeling the centralized air conditioned hydraulic network, with variable flow is presented. It takes the validated data from the net in the mentioned application and inserts it in another application, developed in Delphi software, to run the hydraulic model in a similar way. In the created Delphi application mentioned before, an algorithm was developed which generates the variable codes, facilitating the automation of the topology change of the hydraulic network. This way the changing effects of the hotel occupation on the electric power required by the pump can be evaluated. Also an algorithm is included to determine the more rational rotation speed and a combinatorial optimization which includes the methods: exhaustive simple, exhaustive staggered and genetic algorithm according to the number of occupation variants.

Palavras-chave : centralized air conditioning; variable flow; hotels; operacional optimization; water networks.
