The simulation tool allows the user to choose different parameters related with the simulation process: time-step, accuracy, etc. The smaller the time-step, the longer the simulation time but the more precise are the results concerning the PCM interaction. This statement has to be taken into account when a PCM simulation is carried out. It was […]

Parabolic trough collectors

The models used for the parabolic trough collector fields are based on the model of Lippke [5] which has been developed for solar thermal power plants. The implementation of these models in Greenius has been described in [6]. The model parameters of the specific collector type have been measured at DLR and published in [7]. […]

More results about case 2

Cases 2A and 2B deal with photovoltaic panels, table 4 shows field production on the whole year. PV field feeds grid network, so electricity generation can be done when vapour compression chiller is not operating. Conservative shading assumptions is taken for all other results. For case 2A, PV field produces more than the whole vapour […]

SIGA SOL – Planning module

The planning process for the insertion of renewable energies in rural areas is normally a complex task because it demands an approach with multiple criteria: energy resources, socio-economic indicators, indices of non-electrification, among others. If we addiotinally consider the intention of stimulating regional development through the inclusion of energy systems for productive aims, we have […]

Heat exchanger model

1.1. Model structure There are in general two possible ways to describe the thermal behaviour of a heat exchanger considering its geometry. The first one is to (numerically) solve heat transfer equations using finite element or volume methods, e. g. in FLUENT. However, these models require much computing effort and are, therefore, not appropriate for […]
