Description
- This application claims the benefit of U.S. Provisional Application No. 61/368,866, filed Jul. 29, 2010, which application is hereby incorporated herein by reference, in its entirety.
- The invention relates generally to the air quality of an enclosed space and, more particularly, to a system for introducing fresh air into an enclosed space, particularly a building or home.
- Over the past forty years, the construction industry in the United States focused its efforts on improving occupant comfort in a finished building. A key way to increase occupant comfort involved the introduction of heating, ventilating, and air-conditioning (hereinafter “HVAC”) equipment on a large scale. This equipment allowed occupants to control the interior environment of the building so that the occupant could keep the interior building temperature in a range the occupant considered comfortable.
- Unfortunately, this HVAC equipment increased energy consumption, which in turn increased the cost to own and operate the building. As a result, the construction industry and the HVAC industry began to research the causes behind the large energy consumption of HVAC equipment. The industries discovered that construction standards at the time allowed for air outside the building to seep into the building and conditioned air inside the building to seep out of the building. This seepage, or air exchange, necessitated that the HVAC equipment operate more frequently to keep the interior building temperature in the desired range. Increased operation meant increased energy consumption and increased costs to the building owner/occupant. To combat this, the construction industry has developed methods and practices during the last forty years to decrease the amount of air exchange, in effect the construction industry has developed methods to better seal buildings and decrease the amount of outside air seeping into the interior space.
- A second cause for increased energy consumption related to the HVAC equipment itself. When first introduced, HVAC equipment drew air exclusively from the area outside of the building. The HVAC equipment would then cool or heat the air prior to exhausting the treated air into the interior building environment. The HVAC industry discovered that if the HVAC equipment instead drew air from the interior space, it required less energy to heat or cool the air to the desired temperature, thus reducing costs to building owner/occupant. Presently, HVAC equipment draws air almost exclusively from the interior building space, virtually eliminating the amount of non-recycled air introduced into the building's interior.
- During the time period that buildings became better sealed and HVAC equipment more efficient, the United States has seen a significant increase in the incidence of obesity, diabetes, Alzheimer's, asthma, and birth defects, such as autism, as well as lower energy levels among the populace. This can be traced at least in part to exposure to decreased oxygen levels. In a sealed environment, occupants within the space are breathing air that has already been processed through the occupant's body. Thus, with each breath, the occupant in a sealed environment is reducing the amount of available oxygen. A reduction in available oxygen can lead to a decrease in body functions, causing the body to burn fewer calories and store more fat. Similarly, the reduction in the amount of available oxygen is known to exacerbate the symptoms of those suffering from mental illness and increase the instances of asthma. In addition, a reduction in available oxygen can cause mutations in a child's in utero development leading to conditions like autism.
- Therefore, it would be desirable for a system to increase the amount of available oxygen in a building environment, thus helping to reduce obesity, diabetes, Alzheimer's, asthma and the risk of potential birth defects, alleviate the symptoms of mental illness, and increase energy levels of occupants of buildings, without reducing the efficiency of an HVAC system.
- The present invention, accordingly, provides a Fresh Air Recovery System comprising an intake opening in a first wall defining a portion of an enclosed space allowing air on an exterior side of the first wall to pass through the first wall into the enclosed space; and an exhaust opening in a second wall defining a portion of the enclosed space allowing air on an interior side of the second wall to pass through the second wall into an ambient environment.
- The foregoing has outlined rather broadly the features and technical advantages of the present invention in order that the detailed description of the invention that follows may be better understood. Additional features and advantages of the invention will be described hereinafter which form the subject of the claims of the invention. It should be appreciated by those skilled in the art that the conception and the specific embodiment disclosed may be readily utilized as a basis for modifying or designing other structures for carrying out the same purposes of the present invention. It should also be realized by those skilled in the art that such equivalent constructions do not depart from the spirit and scope of the invention as set forth in the appended claims.
- For a more complete understanding of the present invention, and the advantages thereof, reference is now made to the following descriptions taken in conjunction with the accompanying drawings, in which:
-
FIG. 1 exemplifies a perspective view of a building embodying features of the fresh air recovery system of the present invention; -
FIG. 2 illustrates a plan view of the building ofFIG. 1 ; -
FIG. 3 illustrates an elevation view of the building ofFIG. 1 ; and -
FIG. 4 exemplifies a perspective view of an alternative building embodying features of the fresh air recovery system of the present invention. - In the following discussion, numerous specific details are set forth to provide a thorough understanding of the present invention. However, it will be obvious to those skilled in the art that the present invention may be practiced without such specific details. Additionally, for the most part, details concerning basic building construction and materials and the like have been omitted inasmuch as such details are not considered necessary to obtain a complete understanding of the present invention, and are considered to be within the skills of persons of ordinary skill in the relevant art.
- Referring to
FIG. 1 , there is shown a freshair recovery system 10 having an exemplified by abuilding 100 defining an enclosedspace 200. Thebuilding 100 comprises at least afirst wall 101, asecond wall 102, athird wall 103, afourth wall 104, afloor 105, and aceiling 106, each defining a portion of the outer boundaries of thebuilding 100. The enclosedspace 200 comprises a volume of air that is sealed from a volume of air existing outside of the enclosedspace 200. In the embodiment exemplified, air cannot pass between the enclosedspace 200 and a space outside of thebuilding 100. As used herein, the term “sealed” implies a negligible (possibly zero) rate of air transfer across the outer boundaries of thebuilding 100 such that an entity placed within the enclosedspace 200 that relies upon oxygen respiration to survive will deplete the available amount of oxygen in the air contained within the volume of the enclosed space over time. - In accordance with principles of the present invention, the
building 100 preferably includes afirst opening 301 and asecond opening 302 strategically positioned to facilitate maximum air flow through theentire space 200. By way of example, and as exemplified inFIG. 1 , thefirst wall 101 further defines afirst opening 301 preferably located proximate to theceiling 106 and thethird wall 103. Thesecond wall 102 further defines asecond opening 302 preferably located proximate to thefloor 105 and thefourth wall 104. An electronically controlledvent 311, preferably having varying states of being open between completely open and completely closed, fits within the first wall opening 301 such that movement of the vanes of thevent 311 may alternatively allow more or less air to pass through the first wall opening 301 between the area outside thebuilding 100 and the enclosedspace 200. Similarly, anexhaust fan 312 fits within the second wall opening 302 such that operation of theexhaust fan 312 alternatively increases and decreases the volume of air passing from the enclosedspace 200 to the area outside of thebuilding 100. Thefan 312 is preferably configured to be operable at a variable speed. A person of ordinary skill in the art will understand that the locations of the first wall opening 301 and thesecond wall opening 302 may vary in order to maximize the air flow rate between the enclosedspace 200 and the area outside thebuilding 100. - In a preferred embodiment, an
electronic controller 300 is coupled to thevent 311 viaelectrical wires 304 and to theexhaust fan 312 viaelectrical wires 304 for controlling operation of each. Thecontroller 300 is preferably configured for manual operation and/or automated operation utilizing a timer (preferably integrated into the controller), an oxygen sensor, a carbon dioxide sensor, humidity sensor, and/or an air pressure sensor. The oxygen sensor, carbon dioxide sensor, humidity sensor, and/or air pressure sensor are preferably positioned both the interior and exterior of thebuilding 100, preferably proximate to thevent 311 and/or wherever people generally reside or sleep, and are coupled to thecontroller 300 via wires 308. The sensors positioned on the interior of thebuilding 100 are designated collectively by thereference numeral 320, and the sensors positioned on the exterior of thebuilding 100 are designated collectively by thereference numeral 322. While it is preferred that both interior and exterior sensors be used, the system is operable with only interior sensors, or even no sensors, and as discussed below, is operable manually. - In a first preferred embodiment, the
exhaust fan 312 and thevent 311 are manually controlled via thecontroller 300, necessitating that the operation of each device occur at the initiation of manual action. In a second preferred embodiment, theexhaust fan 312 and thevent 311 are electronically controlled by the timer coupled to thecontroller 300 that initiates the operation of theexhaust fan 312 and thevent 311 at timed intervals throughout a 24-hour period. - In a third preferred embodiment, the
exhaust fan 312 and thevent 311 are electronically controlled by theoxygen sensors controller 300 that initiates operation, to the degree necessary, of theexhaust fan 312 and thevent 311 when theinterior oxygen sensor 320 reads less than a preset level of oxygen within the volume of space where theoxygen sensor 320 is placed, and theexterior oxygen sensor 322, if there is one, reads a higher level of oxygen. - In a fourth preferred embodiment, the
exhaust fan 312 and thevent 311 are electronically controlled by thecarbon dioxide sensors controller 300 that initiates operation, to the degree necessary, of theexhaust fan 312 and thevent 311 when the interiorcarbon dioxide sensor 320 reads more than a preset level of carbon dioxide within the volume of space where the carbon dioxide sensor is placed, and the exteriorcarbon dioxide sensor 322, if there is one, reads a lower level of carbon dioxide. - In a fifth preferred embodiment, the
exhaust fan 312 and thevent 311 are electronically controlled by thehumidity sensors controller 300 that initiates operation, to the degree necessary, of theexhaust fan 312 and of thevent 311 when the interiorhumidity sensors sensor 320 reads more than a preset level of humidity within the volume of space where the carbon dioxide sensor is placed, and theexterior humidity sensor 322, if there is one, reads a lower level of humidity. - In a sixth preferred embodiment, the
exhaust fan 312 and thevent 311 are electronically controlled by theair pressure sensors controller 300 that initiates opening to the degree necessary of the vent 311 (1) to decrease air pressure when the interior air pressure is high and exterior air pressure is low, or (2) to increase air pressure if interior air pressure is low and exterior air pressure is high. Alternatively, if both interior and exterior air pressure are high, then theexhaust fan 312 may be activated to pass air from the interior to the exterior. If both interior and exterior air pressure are low, then theexhaust fan 312 may be activated in reverse to pass air from the exterior to the interior. Theair pressure sensors vent 311 before or after powering off afan 312 as needed to maintain air pressure. A person of ordinary skill in the art will understand that the means for controlling theexhaust fan 312 and thevent 311 may alternatively use any of the above means in combination with one another such that the overall system operates as described below. - When operation is desired, e.g., a manual determination to operate the fresh
air recovery system 10 is reached, a preset oxygen level is reached, a preset carbon dioxide level is reached, a preset time occurs, and/or a preset air pressure is reached, as discussed above, thevent 311 is activated so that outside air (i.e., air outside the building 100) may freely flow into theenclosed space 200. In addition, theexhaust fan 312 is operated, preferably synchronously with thevent 311, to draw air within theenclosed space 200 into the area exterior to thebuilding 100. Alternatively, operation of theexhaust fan 312 and thevent 311 may reverse the air flow, drawing outside air into theenclosed space 200 through theexhaust fan 312 and exhausting air through thevent 311. Operation of theexhaust fan 312 and thevent 311 continues until the air within theenclosed space 200 is sufficiently exchanged with air outside theenclosed space 200, e.g., a manual determination is made to cease operation, a preset oxygen level is reached, a preset carbon dioxide level is reached, and/or a preset time occurs. If thebuilding 100 is equipped with HVAC, then the HVAC is preferably powered off while thevent 311 andfan 312 are operating. -
FIG. 4 exemplifies an alternative embodiment of the invention in whichbuilding 400 comprises multiple rooms, exemplified as tworooms building 400 is preferably provided with onefan 312, but eachroom respective vent vent 311 is preferably provided with an oxygen sensor, a carbon dioxide sensor, humidity sensor, and/or an air pressure sensor, collectively designated with thereference numeral 320 for interior (of room 410) sensors, and collectively designated with thereference numeral 322 for exterior (of room 410) sensors, as described above. Similarly, thevent 411 is preferably provided with an oxygen sensor, a carbon dioxide sensor, humidity sensor, and/or an air pressure sensor, collectively designated with thereference numeral 420 for interior (of room 410) sensors, and collectively designated with thereference numeral 422 for exterior (of room 410) sensors, as described above. Thefan 312 andvents controller 300 manually or automatically from therespective sensors vent 311, andsensors vent 411. Similarly as described above with respect toFIG. 1 . Adoor 414 between the rooms allows for air to flow between the rooms. Thedoor 414 may optionally have a raised lower edge to allow air flow even when the door is closed. In operation, thecontroller 300 runs thefan 312 while eachvent vent multiple fans 312 may be employed. - In further alternative embodiments, additional walls may exist within the
enclosed space 200 defined by the outer boundaries of thebuilding 100. In these instances, additional openings may be placed within the interior walls to allow for free passage of air throughout theenclosed space 200. A person of ordinary skill in the art will also understand that the first wall opening 301 and the second wall opening 302 may include filters and other media to inhibit the movement of undesired objects and allergens from passing into theenclosed space 200. In addition, other embodiments may includemultiple exhaust fans 312 and/ormultiple vents 311 as needed to efficiently exchange air within the enclosed space for air outside the enclosed space. Still further, the fresh air recovery system of the present invention may be integrated into an otherwise conventional system that has ventilation already installed within thebuilding 100. Still further, the one ormultiple exhaust fans 312 and one ormultiple vents 311 may be electronically coupled via thewires multiple exhaust fans 312 is always synchronized with operation of the one ormultiple exhaust fans 312, so that relatively constant air pressure within thespace 200 is maintained, the air pressure preferably being sensed by an air pressure sensor coupled with thecontroller 300. - It may be appreciated that by implementing the present invention, many advantages over the conventional art is obtained. For example, the amount of available oxygen in a building environment is increased, thus helping to reduce obesity, diabetes, asthma, the risk of potential birth defects, and Alzheimer's, increase occupant energy levels, and alleviate the symptoms of mental illness. Moving a relatively large quantity of air through a building relatively quickly over a short period of time is much more efficient than having air slowly leaking in continuously through, e.g., cracks in window seals.
- Having thus described the present invention by reference to certain of its preferred embodiments, it is noted that the embodiments disclosed are illustrative rather than limiting in nature and that a wide range of variations, modifications, changes, and substitutions are contemplated in the foregoing disclosure and, in some instances, some features of the present invention may be employed without a corresponding use of the other features. Many such variations and modifications may be considered obvious and desirable by those skilled in the art based upon a review of the foregoing description of preferred embodiments. Accordingly, it is appropriate that the appended claims be construed broadly and in a manner consistent with the scope of the invention.
