Personalized air conditioning/ displacement ventilation system

Abstract

A personalized air conditioning / displacement ventilation system is located above a floor having an air plenum below the floor but above the concrete slab. A displacement ventilation stand-alone air chamber is located above the floor and thereby delivers air above the air plenum. The air chamber has a frontal outlet and a lateral air outlet into the ambient atmosphere. Within the stand-alone chamber the air is being displaced in various amounts to various outlets. The stand-alone unit can be placed wherever it is needed or desired in many locations in a wide open work place as a retrofit.

Description

PRIOR APPLICATIONS [0001] This application is a Continuation-In-Part of application Ser. No. 11 / 069,453 having a filing date of Mar. 2, 2005.FIELD OF THE INVENTION [0002] The invention at hand relates to either heating or cooling the air in a large building, especially with a floor area having multiple persons working therein. The invention is directed primarily to the personal comfort of a person working at a workstation including a desk by directing conditioned air to the immediate vicinity of the person or persons present at those workstations and by giving those persons control over the flow and direction of the conditioned air, and to providing displacement ventilation to the surrounding area. BACKGROUND OF THE INVENTION [0003] In the field of heating and cooling, generally known as “air conditioning”, there are known problems causing discomfort to the occupants in the building or a room. Inefficiencies in the system result in excessive operating costs in the operation of the b...

AI Technical Summary

Benefits of technology

[0030] Consequently, in the field of heating and cooling there exists a need for providing a flow of conditioned air directly to or near a person sitting at a workstation, without blowing at the person and without creating a draft, as well as to occupants of the surrounding area. More particularly, there exists a need for a workstation to be so equipped wherein the occupant can individually control and obtain the amount of conditioned air supplied within the workstation while maintaining a desirable flow of conditioned air to surrounding areas. The amount of conditioned air within the workstation is controlled by the person to maximize the comfort level, well being health and level of productivity of each worker, while maintaining a desirable flow of conditioned air to surrounding areas.

Problems solved by technology

In a building whether large or small, for example, the control of temperature, air flow, humidity and the like, or even individual rooms and workstations leaves many persons in the building or within a room or in the vicinity of a workstation uncomfortable or dissatisfied with the condition of their particular environment.

Also, different locations in a building or on a floor, or even a single room or closer yet in the vicinity of a workstation, are not satisfactorily heated or cooled, that is, air conditioned, and give rise to complaints about discomfort and illness, resulting in absenteeism, sickness and, of course, loss of productivity.

Further, conventional air conditioning systems generally require expensive duct work and installations, usually in floors or ceilings or both, which cause unnecessary heating or cooling of unused space, particularly the spaces that surround the duct work and the spaces above the head level of the occupants.

The above mentioned duct work also imposes a substantial energy demand for the movement of air through the ducts and additionally presents difficulties in cleaning the ducts.

Such prior art systems also created complaints of discomfort caused by high or low air velocities or high or low temperatures depending upon the location of the air outlet grilles.
