Air distribution of low-temperature air supply system for an office building

For the central air conditioning system of this building, designs the low-temperature and conventional-temperature air supply systems, and presents their comparison. Studies the practicability of the applying ordinary diffuser to low-temperature air supply system, analyses the influence of the factors on the air distribution such as air diffuser structure type, dimension properties, supply air speed, supply air temperature, location etc. Concludes that the ordinary radial diffuser can meet the requirements of low-temperature air supply system, and presents some reference values for designing.
