Evaluation of building ventilation systems
Journal of Safety Research, 1986Over the past several years, NIOSH has responded to health hazard evaluation requests from workers in dozens of office environments. Typically, the employees have complained of headache, eye and upper respiratory tract irritation, dizziness, lethargy and the inability to concentrate.

Inspecting ventilation systems
Structural Survey, 1995Highlights the need to inspect ventilation systems, which will become a legal requirement for all workplaces from 1996. Beneficial reasons are given, including maintaining the health and efficiency of employees, maintaining the quality of the indoor environment, and protecting the safety and efficiency of plant.

‘Ventilator System Composition’ describes in depth, each of the six essential parts: the electrical supply, compressed gas supply, ventilator, breathing circuit, artificial airway, and the patient’s lungs. The chapter discusses the internal design of the ventilator, particularly the inspiratory channel and expiratory channel, and the use of a ...

Residential Ventilation Systems
2020Historically, homes were not designed to include whole-house mechanical ventilation. Residential building envelopes were so leaky that considerable natural air exchange occurred without mechanical ventilation systems. As homes have become tighter to save energy and provide better comfort, mechanical ventilation has become necessary to ensure enough ...

‘Ventilator System Concept’ develops the idea that the equipment for mechanical ventilation is a ventilator system with six essential parts. Using a simple balloon model, it explains the operating principle and composition of a ventilator system, and it describes how the system generates intermittent positive airway pressure.

Subsurface ventilation systems
1993Practically every underground opening is unique in its geometry, extent, geological surroundings, environmental pollutants and reasons for its formation—natural or man made. The corresponding patterns of airflow through those openings are also highly variable.
