Opis (srp)

Heating, ventilation and air-conditioning (HVAC) systems are an indispensable part of today's living comfort. At the same time, those systems are significant energy consumers1, and their energy-efficient work is crucial. Since increasing their share lowers carbon dioxide emissions into the atmosphere, improves energy supply security, and reduces reliance on imports of electricity and energy raw materials, it is quite common for such systems to be integrated with non-conventional, renewable energy sources. However, when a system integrates multiple different energy sources, storage media, and consumer appliances, the task of monitoring and controlling energy flows, becomes too complicated for human operation, raising the question of how important it is to use the right software for these purposes. The considered multi-source/sink HVAC system [1] features a non-standard reversible water-to-water heat pump (HP) integrated hybrid technology that combines three different renewable energy sources: geothermal horizontal heat exchangers (GHXs), air-to-water exchanger (AHX or a dry cooler unit), and solar electric and thermal energy sources in the form of solar collectors (PVTs), Figure 1. The heat pump operates in two primary hydronic loops between source- and user- thermal buffers, that guarantee stability and decoupled operation of source side and user side of the plant. Finally, the heating, ventilation and air-conditioning are carried out through two terminal units: radiant floor (RF) system equipped with state-of-the-art phase-change materials [2] and air-handling unit (AHU). Entire system is operated by proper actuation over circulation pumps and three-way valves installed according to the required system operability. This multi-source heat pump (MSHP) based technology found its suitable demo-site in one of the facilities of the University of Ferrara, in Italy, which is utilized as the snack bar. Before the new technology was installed, the system had been air-conditioned using the legacy all-air system, which has been kept in place. The existing air-handing unit has been slightly modified by incorporating a new finned coil heat exchanger in addition to the original one. In that way, old and new HVAC systems maintained their hydraulic independence while still both being operational.
