4. Serie H - Surgical Rooms Air Conditioning The air conditioning system for surgical rooms must assure a High Air Quality

5. Serie H - Surgical Rooms Air Conditioning To get it six goals must be achieved

6. Serie H - Surgical Rooms Air Conditioning

7. Serie H - Surgical Rooms Air Conditioning First goal Elimination or minimization of chemical contamination due to the anestetical gas

8. Serie H - Surgical Rooms Air Conditioning First goal Elimination or minimization of chemical contamination due to the anestetical gas Second goal Elimination of bacteriological contamination coming from the external environement

9. Serie H - Surgical Rooms Air Conditioning First goal Elimination or minimization of chemical contamination due to the anestetical gas Second goal Elimination of bacteriological contamination coming from the external environement Third goal Elimination of bacteriological contamination coming from the surrounding environments

10. Serie H - Surgical Rooms Air Conditioning First goal Elimination or minimization of chemical contamination due to the anestetical gas Second goal Elimination of bacteriological contamination coming from the external environement Fourth goal Reduction of batteriologicalcontamination due to the surgical team or to the patient himself Third goal Elimination of bacteriological contamination coming from the surrounding environments

11. Serie H - Surgical Rooms Air Conditioning First goal Elimination or minimization of chemical contamination due to the anestetical gas Second goal Elimination of bacteriological contamination coming from the external environement Fifth goal Guaranty a good level of control of temperature and humidity Fourth goal Reduction of batteriologicalcontamination due to the surgical team or to the patient himself Third goal Elimination of bacteriological contamination coming from the surrounding environments

12. Serie H - Surgical Rooms Air Conditioning First goal Elimination or minimization of chemical contamination due to the anestetical gas Second goal Elimination of bacteriological contamination coming from the external environement Fifth goal Guaranty a good level of control of temperature and humidity Sixth goal Obtain the first 5 goals guarantiing the maximum energy saving Fourth goal Reduction of batteriologicalcontamination due to the surgical team or to the patient himself Third goal Elimination of bacteriological contamination coming from the surrounding environments

13. Serie H - Surgical Rooms Air Conditioning First goal Elimination or minimization of chemical contamination due to the anestetical gas Chemical contamination cannot be filtered. The only solution is the dilution with a great quantity of fresh air

14. Serie H - Surgical Rooms Air Conditioning The fresh air flow must be constant in time even if the filters become dirty and therefore raise there pressure drop. First goal Technical considerations

15. Serie H - Surgical Rooms Air Conditioning Supply section with F9 filter. Constant air flow to the surgical room

16. Serie H - Surgical Rooms Air Conditioning Fan speed controler on both supply and exhaust fans as standard

17. Serie H - Surgical Rooms Air Conditioning The bacteriological pollution coming from outside is eliminated through the absolute filters to be fitted at the end of the supply ducts: H12 for general surgery, and H14 for orthopedics and more delicate operations. Second goal Elimination of bacteriological contamination coming from the external environement

18. Serie H - Surgical Rooms Air Conditioning The absolute filter must be the last component of the aeraulic circuit since everything between it and the patient can contaminate the treated air. The absolute filter is therefore installed in the surgical room immediately above the operating bed. Second goal Technical considerations

19. Serie H - Surgical Rooms Air Conditioning The EN10339 Standard , for the duration in time of the fresh air filters, foresees that before an absolute filter another F9 fine filter be installed and before this a G4 filter. Second goal Technical considerations

20. Serie H - Surgical Rooms Air Conditioning The blocking device of the filter on its gasket must guaranty that the air cannot by-pass the filter itself. The good efficency of the filtrating section must be guarantied and not only of the filter according to the EN 1886 Standard Second goal Technical considerations

21. Serie H - Surgical Rooms Air Conditioning Third goal Elimination of bacteriological contamination coming from the surrounding environments The batteriological contamination coming from the surrounding environments is eliminated by mantaining the room is overpressure respect to them.

22. Serie H - Surgical Rooms Air Conditioning Third goal Elimination of bacteriological contamination coming from the surrounding environments To mantain an environment in over/underpressure in respect to a reference one it is sufficient to extract more or less air than the one supplied in.

23. Serie H - Surgical Rooms Air Conditioning Third goal Elimination of bacteriological contamination coming from the surrounding environments The opposite is true in case of septic or dirty operations; the surgical room must be mantained in depression so not to pollute the surrounding environements.

24. Serie H - Surgical Rooms Air Conditioning A differential pressure pressostat mounted between the surgical room and the clean corridor informs the microprocessor of the situation of over/underpressure in the room. The microprocessor then confronts this with the desired situation and acts on the exhaust fan inverter raising or reducing the quantity of the expelled air from the environment. Third goal Technical considerations

25. Serie H - Surgical Rooms Air Conditioning Mounting within the room

26. Serie H - Surgical Rooms Air Conditioning Fourth goal Reduction of batteriological contamination due to the surgical team or to the patient himself The endogenous batteriological pollution from the patient or from the surgical team is eliminated by filtering with absolute filters as frequently as possible the treated air.

27. Serie H - Surgical Rooms Air Conditioning How is it done? With treatment sections that guaranty the high quantity of fresh air throught thermodynamic components both for the control of humidity and temperature with modulating capacity control. Even in the case of direct expansion units the frigorific capacity is modulated by an electronic injection of hot gas. Fifth goal Guaranty a good level of control of temperature and humidity

28. Serie H - Surgical Rooms Air Conditioning How is it done? Raising as much as possible the recirculation: obviously in respect to the local Standard. Sixth goal Obtain the first 5 goals guarantiing the maximum energy saving

29. Serie H - Surgical Rooms Air Conditioning How is it done? Night Stand-by of the units, activable from the presence feelers, BMS, hour timetables or manualy: Reducion of the capacity by 1/3 of the nominal one, external one Mantaining the overpressure Raising the dead range from 0,3 ° to 10 ° Sixth goal Obtain the first 5 goals guarantiing the maximum energy saving
