VENTILATION AND AIR CONDITIONING SYSTEMS AS AIR NOISE SOURCES IN NAVY SHIPS AND BOATS

Ventilation Systems, US NAVY SHIPS

Shipboard ventilation systems supply and remove air to/from spaces throughout the ship. In doing so, these systems control quality of breathing air and protect personnel and sensitive equipment from potentially hazardous airborne contaminants, fires, explosions, and excessive heat. The ability of ventilation systems to protect personnel from these hazards is particularly important aboard Navy s...

Modelica Library for Building Heating, Ventilation and Air-Conditioning Systems

This paper presents a freely available Modelica library for building heating, ventilation and air conditioning systems. The library is based on the Modelica.Fluid library. It has been developed to support research and development of integrated building energy and control systems. The primary applications are controls design, energy analysis and model-based operation. The library contains dynami...

Passive Energy Air-to-Water Heat Pipe Based Heat Exchanger and its Potential of Air Pre-cooling in Air Conditioning Systems for Iran Climate

Air pre-cooling equipment is normally being employed in air-conditioning systems for pre-cooling the ambient outdoor air to enhance the air-conditioning systems performance. In this study, the potential of a passive water-to-air heat pipe based heat exchanger (HPHEX) for air pre-cooling purpose in air-conditioning systems for the high cooling load demanding regions of Iran was investigated. To ...

Ventilation and Air Distribution Systems in Buildings

The need of building occupants for ventilation has been recognized many centuries ago; however, since the early 1970s, ventilation systems for buildings and transport systems have considerably evolved. This was invigorated by researchers who demonstrated the requirements for buildings to provide comfort and good air quality indoors (e.g., Fanger, 1972; Fanger and Christensen, 1986; Fanger, 1988...
