Concepção e dimensionamento de redes de dutos de ventilação Para unidades de tratamento intensivo

Abstract

The indoor air quality (QAI) of hospitals should be ensured so that occupants protected from microorganisms in the air. The guarantee of this quality is due to the integration of several factors, which have included since the and their air conditioning systems to the operation and systems. This paper proposes to establish and apply an adequate methodology that should be followed for good practice in designing and ventilation for intensive care units (ICUs) in order to ensure the quality of air interior. The design methodology was applied to the ICU environments of a public hospital of the city of Fortaleza-CE using the method of constant friction and subsequent scaling so that the pipeline network was balanced. The network design was done on the floor of the ICU of the hospital after determination of the dimensions of each duct. In addition to providing results regarding the dimensions of the network, the also provided data on the degree of imbalance present in some parts of the designed system, providing an indication that it should be promoted an opening or closing of records in the pipeline network.
