This paper discusses the application of a new strategy approach for the room air conditioning. The basis of the classification is different aims or ideas of the temperature, gas, particle, humidity distributions and room air flow patterns that can be created within a room. A certain strategy can be applied by using different system combinations of room air distribution, exhaust, heating and cooling methods and their control. The realization of an ideal strategy is also dependent on the operating parameters and internal sources.
Seven years after the groundbreaking Queen's Building, ventilation towers are back on the campus agenda with this passive solar library for Coventry University. How has the design moved forward?
Ventilation design has a long history in China. The ancient pioneers used engineering skills to change the indoor environment. In this review, basic natural ventilation design ideas are introduced from both a historical and modern viewpoint. Attention is paid to new natural ventilation system developments, such as the design and testing of natural ventilation inlets and outlets for the stack and solar chimneys. Theoretical aspects of ventilation design are also considered. Today, the use of mechanical ventilation systems in China is growing for both domestic and non-domestic buildings.
The paper is concerned with the procedure for regulating or balancing a ventilation· system, so as to ensure that each outlet supplies or extracts its proper quantity. It deals with methods, organisation instrumentation and recording of results; it also discusses the accuracy required and attainable in ordinary practice. The advocated method of regulating consists of balancing the proportions of air flow at the junctions of a system, dealt with in a routine order, followed by the adjustment of the complete system to design volume by a final setting at the fan.
