negative pressure ward for hospital
My company is having a job in Hong Kong, which previously had a big virus SARS, so need to convert the normal ward to a negative pressure ward.
By means of extract more air than the supply air, can anyone help me how to carry out the commissioning process, will there be CIBSE commissioning guide to follow?
Re: negative pressure ward for hospital
at last, I have finally finished 2 separate jobs of negative pressure ward, some with an ante room & main bedroom.We need 10 Pa differential between ward & corridor.
My working experience is you must do a first class workmanship air duct and test the leakage of air duct, according to DW144, it is better to test the air duct with the air duct branch duct attached, seal up with plastic bags. both supply & exhaust need to be tested. Minor leakage will not maintain the differential pressure, and the sealing of the wall openig & gaps between ward need very special attention, minor leakage will not get the ideal negative pressure, also our government spend a lot of money to those wards

Well done Watana, yes leak testing of the ductwork is most important when you are attempting pressure differentials across rooms.
Also, thank you for giving us an update on this thread.:)
