OVERVIEW

The course aims to present the technological aspects for the management of hospital facilities. The student will be provided with basic knowledge on the electrical plant engineering part relating to the description of medium and low voltage systems and on the basic knowledge of thermal plant engineering.

Students will acquire training related to hospital systems useful for entering public and private structures in the sector and for active participation in teams for the management of complex structures, systems and biomedical equipment. The knowledge will range from electrical safety problems (plant engineering, protection from faults, power supply continuity and energy efficiency) to thermal energy issues (mass and energy balances, air conditioning, heating and refrigeration systems).

The knowledge will range from electrical safety problems (plant engineering, protection from faults, power supply continuity and energy efficiency) to thermal energy issues (mass and energy balances, air conditioning, heating and refrigeration systems).

The student will be able to understand electrical distribution diagrams, electrical safety principles for personnel and equipment, service continuity systems. For the thermal part, the student will acquire basic knowledge of mass and energy balances, air conditioning, heating and refrigeration. Existing systems will be visualized in order to have a technical-functional vision of hospital structures for electrical and thermal systems.

PREREQUISITES

Knowledge acquire in any Laurea Triennale (BsC course).

TEACHING METHODS

Frontal lectures and visits to Real Hospital Sites.
