A method for producing a fluidic device ( ) for exciting an oscillating jet ( ) of predetermined oscillation and mixing characteristics. The fluidic device ( ) includes a chamber ( ) having a fluid outlet ( ) longitudinally displaced from a fluid inlet ( ). The fluid inlet ( ) is disposed such that in use the fluid ( ) entering the chamber ( ) through the fluid inlet ( ) separates from the inner surface of chamber ( ) to excite an oscillating jet ( ). The method includes the step of configuring the geometry of the shape and/or dimensions of the cross section of the fluid inlet ( ) to determine the mode of oscillation and mixing characteristics of the oscillating jet ( ). A fluidic device ( &prime;) for exciting an oscillating jet ( &prime;) whose characteristics can be determined to meet operational requirements.

Controlling the motion of a fluid jet

An air conditioned space is cooled within a narrow target zone (as depicted on a psychrometric type chart) within which human occupants of the conditioned space would feel thermally comfortable, wherein factors including the heat transfer resistance of occupants' clothing and level of physical activity determine the target zone, by a method which includes correction of operative temperature, relative air velocity and humidity within the conditioned space, inherently controlling humidity by control of effective dehumidifier size while maintaining a low face velocity of air and a high velocity of coolant flow, but varying either, or both, dehumidifier size and the leaving air temperature if humidity ratio falls below four or exceeds thirteen grams of water per kilogram of dry air.

Method and means of air conditioning

An air conditioner dehumidifier comprising coil portions cooled by a fluid coolant such as by chilled water or refrigerant. As the required air sensible and latent cooling demands and their ratio varies in the conditioned space, the number of operational coil portions and the velocity of the coolant flow through each is controlled, by valves or other means, increasing coolant velocity while reducing the number of operational coil portions and vice-versa, to provide the coil surface area and the coil surface temperature necessary to cause the required degree of dehumidification and the required degree of sensible cooling in the required ratio to maintain comfortable conditions in the conditioned space with low energy consumption at all cooling demands.

Air conditioning and method of dehumidifier control

An air conditioner dehumidifier comprising coil portions cooled for example by chilled water or refrigerant. Under part load conditions, restriction of coolant flow below peak load flow, or its total elimination, is limited to some only of the coil portions, while the remainder may receive as much or more coolant flow as at peak load conditions. The relatively unrestricted coolant flow through this remainder can be greater than that under peak load conditions due to more pump output being available to supply the reduced active size of the coil.
