OBJECTIVE OF VIRTUOSO Objective of virtuoso The main aim of VIRTUOSO is to reduce the number of SARS-CoV-2 infections due to health-care-associated transmission and consequently reduce the number of healthcare workers affected by COVID19. To achieve this, VIRTUOSO aims to develop a ventilation system to isolate hospital rooms hosting infectious patients. Complete isolation of the contaminated environment is achieved by bringing the hospital room under negative pressure. VIRTUOSO can automatically guarantee and maintain this condition. The system consists of a small number of components that can...

SYSTEM COMPONENTS System components N.B The duct exiting the shutter (ref. 4) can be conveyed with a diffuser in the external environment or connected to an expulsion pipe where provided. This project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement Nº101016203.

SYSTEM COMPONENTS The main components of the system are: EVS Fan Box (Ref. 2) dim. 1000x580x580mm complete with silencers, pressure differential and motor disconnect switch with two outlet channels installed in the false ceiling of the bathroom of the room. Two shutters with high switching speed (ref. 3 and 4), which allow the recirculation of air inside the room (through the internal filter ref. 5) or in the corridor (through the external filter number 5). This project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement Nº101016203....

SYSTEM COMPONENTS • Diffusers equipped with high flow H14 absolute filters, so that neither the recirculation air nor the air knife carry contaminants N.B. Filter replacement to be carried out by qualified personnel with suitable PPE and anti-contamination procedure with relative disposal at an authorized centre. Air intakes (ref. 9), above patients’ beds, are equipped with G4 filters, to reduce the risk of blocking the H14 filters with large contaminants (e.g. dust). 4 B.B.IMPIANTI SRL via della Cerca Nr.6 22070 LURAGO MARINONE (CO) Tel +39 031 35 21 978 Tel +39 348 22 96 566 [email protected]...

SYSTEM COMPONENTS NodeIO control with integrated management software, door opening control sensor, fan speed control, filter pressure differentials, remote assistance module or VPN provided by the structure. Touch HMI, to view the parameters and enable the control/set up of the system after entering a security code (different background display according to the mode of use). This project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement Nº101016203.

SYSTEM COMPONENTS Camera (optional) (Ref. 14), to allow operators to quickly check on patients without opening the room door. This project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement Nº101016203.

CONTROL PANEL Control panel Figures 1 to 10 show the screens of the TOUCHPAD positioned outside the hospital room Figure 1 shows the main page of the panel containing a description of the Virtuoso project Figure 1 On the left of the page is the selection menu: used to navigate the pages. This project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement Nº101016203.

CONTROL PANEL SELECTION MENU Main page Environment camera Operating mode selection This project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement Nº101016203.

ENVIRONMENT CAMERA Environment camera This page [Figure 2] allows the user to use the video camera inside the hospital room. It is possible to activate and deactivate the camera using the “Start” and “Stop” buttons. This project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement Nº10

OPERATING MODE Operating mode This page allows the user to select the 3 operating modes of the Virtuoso system: 1. 2. 3. Deactivate - system shutdown Room recirculation - activation of ventilation and damper inside the room Negative pressure Level 1 - ventilation activation, damper modulation to maintain negative pressure in the room with partial internal recirculation. When the door is opened, the ventilation rises to maximum level and the air is all sent outside for a certain period. The ventilation is then reduced and the shutters partialized for a long period until the initial conditions...
