DA-88-03-2 -- Spot Cooling/Heating and Ventilation Effectiveness PDF

The supply of conditioned air to a space is a necessary function in modern of£ice buildings and manufacturing plants. Heating and cooling loads, ventilation requirements, odor and humidity control all combine to establish air supply requirements to a space, The comfort and functional parameters of the occupy.his and equipmeuL determine the distribution within the space.

The need for spot cooling is determined by the functional requirements of the space to be conditioned. Design parameters and jet dynamics are discussed in the paper, and some general application rules are presented.

Task air conditioning has a number of advantages over space conditioning. Ventilation can be assured, and local loads can be handled directly. Occupants can have more control over their local environment. Loads can be handled more efficiently.

Manufacturers of these units have the most experience, and can provide the best application guides, but most of their published data is not applicable to the available equations for jet dynamics. Some general application guidelines have been provided to allow an engineered selection of units for differing applications.
