Heat reclamation and air circulation device

Abstract

A device for reclaiming heated air near the ceiling of a room by circulating it to the lower portions of a room which reduces thermal stratification and distributes warm room air, which, improves comfort and heating efficiency, and in cooling mode, can be turned 180 degrees in the vertical plane to move cool air from the floor to the ceiling. Suspended from the ceiling by a small hook, the lightweight double walled fabric structure provides insulation against heat loss of the moving air, and contains a quiet and efficient fan at the bottom of the inner tube assembly which directs airflow into the room through a deflector crafted from a folded fabric sheet. The inner tube is held open against the negative pressure generated by suction of the fan by external springs attached to the outer wall of the inner tube, each spring fashioned from two struts connected by a short segment of elastic polymer.

What is claimed is: 
     
         1 . A reversible heat reclamation and air circulation device comprising:
 a double-walled tube including an inner tube and an outer tube, and upper and lower foam collar disks that provide mounting for uplighting, down lighting and electronics outside the inner tube so as not to adversely affect air flow and provide for simple construction and end user applied upgrades.   
     
     
         2 . The device of  claim 1 , wherein the double-walled tube is formed of a soft, pliable, translucent, lightweight tube material. 
     
     
         3 . The device of  claim 1 , wherein the fan is mounted at the bottom of the tube for efficiency, quiet operation, and ease of powering from a wall outlet. 
     
     
         4 . The device of  claim 1 , wherein a fan at the bottom and the top of the tube, or multiple fans in segmental fashion will provide additional power without increase in size. 
     
     
         5 . The device of  claim 1 , wherein the air conducting inner tube assembly is constructed using a series of lightweight cylinders and fabric tubes that can be attached using tape. 
     
     
         6 . The device of  claim 1  further comprising external springs to maintain the inner-walled tube open during operation. 
     
     
         7 . The device of  claim 1  further comprising an origami-type folded piece of material to form a lightweight, durable, and adjustable air deflector which can be securely attached to a tube using an elastic band or tape. 
     
     
         8 . A spring device that provides for an external method to hold open a collapsible tube under negative pressure. 
     
     
         9 . The spring device of  claim 8  compromising two rigid struts substantially equal in length to an outer diameter of an inner tube used as part of a conduit to transfer air, wherein the two rigid struts are connected by a short segment of elastic material, which is attached to the outer wall of the inner tube which has been flattened and wherein, when released, the springs hold the walls of the inner tube open, in a triangular shape. 
     
     
         10 . A device in the form of a sheet folded to form a lightweight and durable air deflector that is resistant to tearing and can be deformed or crushed and then retain its original shape without loss of function. 
     
     
         11 . The device of  claim 10 , wherein the deflector can be adjusted, yet securely attached to a tube using Velcro®, an elastic baud, or tape alone.
