The embodiments described herein relate generally to heating, ventilating, and air conditioning (HVAC) systems. More particularly, the present embodiments relate to various systems, components and methods for implementing HVAC upon temporary structures.
Existing methods for the heating, ventilating, and air conditioning (HVAC) of temporary structures have generally included ad-hoc temporary structure HVAC systems centered around commercial, off the shelf HVAC units. At least one known method to cool a temporary structure includes utilizing HVAC units that can be noisy or include generally aesthetically unpleasing or homemade components taking on an improvised or unprofessional appearance. For example, many temporary structure HVAC systems have utilized readily available building materials such as 2×4 lumber and plywood. Additionally, at least some known HVAC systems include ducting that extends beneath a malleable wall of the temporary structure to channel air into the structure. Such ducting may create undesirable gaps between two or more of the wall, the ducting, the floor of the temporary structure, and the ground. Furthermore, at least some known HVAC systems do not allow for adjustability and redirection of air flow.
In one aspect, an air handling unit for use with a heating, ventilating, and air conditioning (HVAC) system is disclosed. The air handling unit includes an air input portion configured to receive conditioned air. The air handling unit also includes an air output portion configured to direct the conditioned air to an interior space of a structure. The air handling unit further includes a routing portion configured to couple the air input portion to the air output portion in fluid communication. The routing portion also includes a contouring structure configured to interface with the structure.
In another aspect, a heating, ventilating, and air conditioning (HVAC) system is also disclosed. The HVAC system can be utilized in a temporary structure defining an interior space and an exterior environment. The HVAC system can include an HVAC unit positioned in the exterior environment and configured to channel conditioned air into an air handling unit. The air handling unit can include an air input portion positioned in the exterior environment, the air input portion including at least one air inlet in fluid communication with the HVAC unit. The HVAC system also includes an air output portion positioned in the interior space for redirecting conditioned air, and a housing connecting the air input portion to the air output portion, the routing portion including a contouring structure configured to interface with the tent.
In yet another aspect, a method of assembling an air handling unit for a tent heating, ventilating, and air conditioning (HVAC) system is disclosed. The method includes forming an air input portion for accepting conditioned air and forming at least one air input receptacle into the air input portion. A further step includes forming an air output portion for directing the conditioned air to the interior space of a tent and forming a routing portion connecting the air input portion and the air output portion. The method includes coupling the routing portion between the air input portion and the air output portion such that the air input portion and the air output portion are in fluid communication. An angled side surface is coupled between a top surface and a bottom surface located on the air input portion, wherein the angled side surface is obliquely oriented between the top surface and the bottom surface.
The disclosure will be readily understood by the following detailed description in conjunction with the accompanying drawings, wherein like reference numerals designate like structural elements, and in which:
Representative applications of methods and apparatus according to the present application are described in this section. These examples are being provided solely to add context and aid in the understanding of the described embodiments. It will thus be apparent to one skilled in the art that the described embodiments may be practiced without some or all of these specific details. In other instances, well known process steps have not been described in detail in order to avoid unnecessarily obscuring the described embodiments. Other applications are possible, such that the following examples should not be taken as limiting.
In the following detailed description, references are made to the accompanying drawings, which form a part of the description and in which are shown, by way of illustration, specific embodiments in accordance with the described embodiments. Although these embodiments are described in sufficient detail to enable one skilled in the art to practice the described embodiments, it is understood that these examples are not limiting; such that other embodiments may be used, and changes may be made without departing from the spirit and scope of the described embodiments.
One solution to the aforementioned issues is to utilize an air handling unit in a HVAC system for a temporary structure. In some embodiments, the air handling unit includes an air input portion for accepting conditioned air and an air output portion for outputting the conditioned air. The air input portion and the air output portion can be connected via a routing portion. For example, the routing portion is configured to couple the air input portion to the air output portion. The air input portion can include one or more air inlet portions for accepting conditioned air. The air inlet portions can each include a removable plate positionable over the air inlet portions for preventing airflow through the air inlet portions. The air inlet portions can also include flanges circumscribing the air inlet portions for facilitating the connection of an HVAC unit. Conditioned air can include heated air, cooled air, ventilated air, filtered air, humidified air, and de-humidified air. In other embodiments, the air output portion can include a structure for redirecting air such as a pivot mechanism or a cover plate. For example, the air handling unit can be a component of a temporary structure HVAC system. The air input portion can be located in the exterior of the temporary structure, the air output portion can be located interior of the temporary structure, and the routing portion can be located both in between the air input portion and air output portion as well as both the exterior and interior of the temporary structure.
In an exemplary embodiment, the routing portion can include a contouring structure for enhancing aesthetics and thermal efficiency. For example, in a temporary structure HVAC system, the temporary structure can take of the form of a tent, marquee, big top, dome tent, pup tent, teepee, wigwam, gazebo, pavilion, yurt, yaranga, palapa, or any structure not intended to be a permeant fixture. Further, the temporary structure can also include side walls at least partially detached from the ground. The temporary structure can separate an interior space from an exterior environment. The routing portion can reside between the side walls and the ground such as in between the side walls and apportion where the side walls are not attached to the ground. The air input portion can reside in the exterior environment and while the air output portion resides in the interior space. The side walls can fall around the contouring structure of the routing portion and naturally follow the contour of the routing portion by operation of gravity. For example, the contouring structure can include an angled surface such that the side walls naturally let the side wall fall to the ground. In other embodiments, the routing portion can include contouring structure to allow for the ground and side walls to naturally contour around the routing portion. In more embodiments, the interface between the contouring structure and the temporary structure can form an improved seal between the interior space and exterior environment of the tent thereby improving thermal efficiency.
