Description
- The present disclosure generally relates to apparatuses and methods for conditioning the temperature of air for the comfort of individuals proximate to the apparatus. More particularly, the present disclosure relates to an air conditioning system for use in an open air or outdoor setting.
- Leisure time for many individuals includes enjoyment of open air and outdoors environments. For some, this may include hikes through a forest or landscaping the back yard. For others, a round of golf or a sightseeing trip is the preferred activity. However, for many individuals relaxation is composed of entertaining family or friends on the back yard patio. Other open air and outdoor activities are also popular such as informal business gatherings, receptions, and social hours and are typically conducted at poolside, on a large patio, or other similar gathering area. While experiencing the outdoors is a preference of many in their pursuit of leisure, relaxing, and socializing, these activities must usually be accomplished at the mercy of the current whims of the weather. The overwhelming preference for these activities is to conduct them on bright sunshine days. However, in many climes, conducting these activities in direct sunlight also means that the participants are exposed to heat, sunshine, and humidity that, if not within a small comfort band, can become uncomfortable within a short time period.
- Umbrellas, tents and gazebos have been utilized in the past to provide shade for gatherings of various sizes. While, such structures provide areas of shade under which people can gather and can accommodate a larger or smaller numbers of people, these structures do not address the underlying ambient temperature and humidity factors, which are also important elements of comfort. Further, attempting to enclose a tent or gazebo and provide the structure with conditioned air for the comfort of everyone housed therein can be logistically difficult at best and prohibitively costly at worst. Enclosing these structures also counteracts the aesthetic aspects of the open air or outdoor environment, which was originally desired to enhance the gathering in the first place. Such enclosures merely function to force a gathering's population into a single designated space in total without regard to individual preferences or accommodation of sub-groupings of participants.
- In particular, while a particular gathering may involve a significant number of people overall, within the total population of the gathering, a number of smaller intimate groups are occurring simultaneously. These smaller groups may typically involve ten or fewer participants engaged in topical discussions. Individuals typically float from one small group to another during the course of the total event. Thus, while the overall population of the even remains relatively constant, the smaller groups are dynamic and typically vary slightly in size within the size range of ten or fewer over the course of the event.
- The comfort demands of these smaller groups can also vary. Some groups may desire to stand in the sunshine, while other groups may desire the comfort of conditioned air and shade. Therefore, there is a need for providing to smaller groups within a larger event population in an outdoor or open air environment, an apparatus capable of delivering conditioned air for the comfort of the individuals within the smaller group without concurrently detracting from the outdoor or open air experience.
- The present disclosure is generally directed to an outdoor, weather resistant, air conditioning tower for providing thermally conditioned air to users located proximate to the tower includes a tower housing defining at least one ambient air inlet, a first conditioned air outlet vertically positioned at a height to coincide with the torso of a standing human, and a second conditioned air outlet vertically positioned at a height to coincide with the head of a standing human. A fan within the tower housing has a fan inlet communicative with the ambient air inlet for drawing ambient air into the tower for thermal conditioning and also has a fan outlet communicative with the first and said second conditioned air outlets for supplying conditioned air to users. A heat exchanger is interposed between the ambient air inlet and the conditioned air outlet, and a working fluid supply is fluidly communicative with the heat exchanger for thermally conditioning the ambient air.
- In another aspect, the outdoor air conditioning tower includes a tower housing defining at least one ambient air inlet, a first conditioned air outlet vertically positioned at a height to coincide with the torso of a standing human, and a second conditioned air outlet vertically positioned at a height to coincide with the head of a standing human. A fan within the tower housing has a fan inlet communicative with the ambient air inlet for drawing ambient air into the tower for thermal conditioning and also has a fan outlet communicative with the first and said second conditioned air outlets for supplying conditioned air to users. A heat exchanger is interposed between the ambient air inlet and the conditioned air outlet, and an underground working fluid supply conduit is fluidly communicative with the heat exchanger for thermally conditioning the ambient air.
- In another aspect, the tower comprises an exhaust conduit for expelling waste air as a by-product of the conditioning cycle. The exhaust conduit is routed to discharge the waste air at a location and direction away from the users standing around the tower.
- In still another aspect, the tower housing defines a second ambient air inlet, and the tower further includes a mast extending upwardly from the tower housing, and defines an exhaust conduit for expelling waste air as a by-product of the conditioning cycle. A second fan is located within the tower housing and has a fan inlet communicative with the second ambient air inlet for drawing ambient air into the tower and a fan outlet communicative with the exhaust conduit. Also included within the tower housing is a condenser or second heat exchanger interposed between the second ambient air inlet and the second fan inlet. The condenser and heat exchanger are fluidly communicative for cycling the working fluid therebetween during the thermal conditioning cycle.
- In yet another aspect, the mast can include a selectively extendable canopy at an upper end of the mast.
- In a still further aspect, the mast includes at least one selectively illuminable light at an upper end of the mast.

An upright anderect tower housing 120 stands typically greater than the height of a human user. At abase 121 thereof,housing 120 defines a firstambient air inlet 122 and a secondambient air inlet 124. Further, at an intermediate height approximately coincident with the height of ahuman torso 12, one or more first conditionedair outlets 126 are defined about a perimeter oftower housing 120, and at a height approximately coincident with the height of ahuman head 14 one or more second conditionedair outlets 128 are defined about the perimeter oftower housing 120. The outdoorair conditioning tower 100 is designed specifically to direct the conditioned air to impinge upon thehumans 10 standing about the outdoorair conditioning tower 100. It is recognized that thehumans 10 may be seated or be in other positions while residing proximate the outdoorair conditioning tower 100. The conditionedair outlets tower housing 120 can assume many shapes such as cylindrical, multiple stacked cylinders, square, or polygonal as non-limiting examples. - A
mast 160 extends upwardly from an upper portion oftower housing 120.Mast 160 can be decorative, functional, or both. In the present embodiment oftower 100, themast 160 is functional and defines anexhaust conduit 162 for expelling waste air that is a by-product of the air conditioning cycle, being directed away from people standing proximate the outdoorair conditioning tower 100. As illustrated inFIG. 3 ,mast 160 in either a decorative or functional configuration as a waste air exhaust can include a selectivelyextendable canopy 170 at anupper end 164 thereof. Further,mast 160 can also support one or moreilluminable lights 176 atupper end 164 to enable use oftower 100 during periods of darkness. - Positioned within a
base 121 ofhousing 120 is afirst fan 130 having aninlet 132 fluidly communicative with firstambient air inlet 122 and anoutlet 134 fluidly communicative with first and secondconditioned air outlets conditioned air conduits 138. Also positioned withinbase 121 ofhousing 120 is asecond fan 140 having aninlet 142 fluidly communicative with secondambient air inlet 124 and anoutlet 144 fluidly communicative withexhaust conduit 162. - A
heat exchanger 136 is preferably interposed between firstambient air inlet 122 andfirst fan inlet 132, and asecond heat exchanger 146 is interposed between secondambient air inlet 124 andsecond fan inlet 142.Heat exchanger 136 andsecond heat exchanger 146 are fluidly interconnected with a working fluid supply cyclically communicative between theexchanger 136 andsecond heat exchanger 146 via one or more working fluid conduits supplyconduits 150. - In use, a group of
individual humans 10 may congregate around or in the immediate vicinity of outdoorair conditioning tower 100. Assuming the individuals desire to have the air in the immediate area thermally conditioned,tower 100 can be activated usingcontrol panel 156.Controls 156 may be operated manually or set to automatically cycle depending on the desires of the users. Upon activation,fans ambient air inlets ambient air inlet 122 is passed throughheat exchanger 136 whereupon it is thermally conditioned by the flow of working fluid circulating betweenheat exchanger 136 andsecond heat exchanger 146 in an evaporation-condensation cycle well known in the art. As the conditioned air “A” exitsheat exchanger 136 and entersfirst fan 130, the conditioned air is directed throughoutlet 134 offirst fan 130 through conditionedair conduits 138 and subsequently expelled back to the ambient environment through first and secondconditioned air outlets humans 10 gathered therearound. Conditioned air “B” exits from first conditionedair outlets 126 vertically positioned to direct the conditioned air at thetorsos 12 of theusers 10, and conditioned air “B” exits from second conditionedair outlets 128 vertically positioned to direct the air in the vicinity of theheads 14 of theusers 10. - Concurrent with the thermal conditioning of air as it passes through
heat exchanger 136,second fan 140 draws ambient air “A” throughsecond heat exchanger 146 to restore the working fluid to its original state prior to the energy transfer process ofheat exchanger 136. This airflow becomes waste air “C” and is expelled fromoutlet 144 ofsecond fan 140 throughexhaust conduit 162 ofmast 160. - Turning now to
FIG. 2 , an alternate embodiment outdoorair conditioning tower 200 is illustrated. Like features oftower 200 andtower 100 are numbered the same except preceded by the numeral ‘2’. Outdoorair conditioning tower 200 includes atower housing 220 from which extending upward is adecorative mast 260.Decorative mast 260 may also include an extendable canopy or illuminable lights (not shown) as described above at anupper end 264.Housing 220 defines a singleambient air inlet 222 at abase 221 thereof, and conditionedair outlets 226, 228 positioned similarly as with respect totower 100. Afan 230 having aninlet 232 fluidly communicative withambient air inlet 222 and anoutlet 234 fluidly communicative with first and secondconditioned air outlets 226, 228 viaconditioned air conduits 238. A working fluid supply conduit 250 delivers working fluid toheat exchanger 236 from a central or remote reservoir (not shown) and workingfluid return conduit 252 returns working fluid to the remote reservoir after exiting fromheat exchanger 236.Conduits 250, 252 are typically routed underground to prevent clutter to the gathering area or damage fromusers 10. - In use, the users desiring to have conditioned air delivered from
