In the present embodiment,heat recovery apparatus 201 is attached to the bottom of aheating source 203 to create anupward airflow 207.Upward airflow 207 moves past aheating element 209 ofheating source 203.Heating element 209 in the present embodiment is a passage of air heated by agas burner 211. However, alternate embodiments of the present invention may be used with heating sources comprising various different types of heating elements such as, but not limited to, electric heating coils, heating elements containing water heated by a gas burner or electricity, wood burning heating elements, etc. In the present embodiment, heated air withinheating element 209 moves up throughheating element 209 and out achimney 213 and heat from this heated air radiates out into the space being heated. Whenupward airflow 207 flows pastheating element 209 more of the heat fromheating element 209 is carried out into the space than would withoutheat recovery apparatus 201. In alternate embodiments, heat recovery apparatuses can create one or multiple airflows, which may be under or over the hood of the heating source. In another alternate embodiment, the fan in the heat recovery apparatus may be reversed to pull air out of the heating source rather than forcing air into the heating source. This outward airflow will pull heat from the heating element out into the space being heated. -
FIGS. 3A and 3B illustrate the airflow of a heating system using aheat recovery apparatus 301 with aninternal wing 305, in accordance with an embodiment of the present invention.FIG. 3A is a cross sectional side view of the heating system configured withheat recovery apparatus 301 creating an upward airflow, andFIG. 3B is a cross sectional view of the heating system configured withheat recovery apparatus 301 creating a downward airflow. In the present embodimentinternal wing 305 creates aninternal airflow 307 along with anexternal airflow 309.External airflow 309 may serve to pull more of the heat from aheating source 303 into the space being heated. Referring toFIG. 3A , mountingheat recovery apparatus 301 to the bottom ofheating source 303 pointing up creates an upward airflow (i.e., from bottom to top). Referring toFIG. 3B , mountingheat recovery apparatus 301 to the top ofheating source 303 pointing down creates a downward airflow (i.e., from top to bottom). Creating airflow in a downward direction can increase efficiency more than when the airflow is moving in an upward direction. It should be noted that as general rule this covers any external or internal airflow. - In some alternate embodiments of the present invention, the heat recovery apparatus may not be mounted directly on the heating system, but may be positions near the heating system to induce an airflow though the heating system. In some of these embodiments, the heat recovery apparatus may further include devices such as, but not limited to, vanes, deflector, ducts, etc., to direct the airflow to a desired entry location on the heating system.
- In some other alternate embodiments of the present invention, the heat recovery apparatus may further include an air filter/purifier. These embodiments may help to reduce dust in the air and accumulation of dust in the heating system.
- In yet some other alternate embodiments of the present invention, the heat recovery apparatus may be adapted with a humidifier system. These embodiments may help to provide a more comfortable healthier environment in the space being heated.
- In still some other alternate embodiments of the present invention, the heat recovery apparatus may further include a manual fan control in the
control mechanism 111 to override thetemperature sensor 113 andprompt control mechanism 111 to turn the fan on or off. Some of these embodiments may further include means for controlling the speed of the fan. - Having fully described at least one embodiment of the present invention, other equivalent or alternative methods of providing a heating system efficiency increasing apparatus according to the present invention will be apparent to those skilled in the art. The invention has been described above by way of illustration, and the specific embodiments disclosed are not intended to limit the invention to the particular forms disclosed. For example, the particular implementation of the apparatus may vary depending upon the particular type of system on which it is used. The systems described in the foregoing were directed to heating implementations; however, similar techniques are to use efficiency increasing apparatuses on other types of air conversion devices or environmental control systems such as, but not limited to, cooling systems, window mounted air conditioners, air filtration and purification systems, etc. Non-heating implementations of the present invention are contemplated as within the scope of the present invention. The invention is thus to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the following claims.
- Claim elements and steps herein have been numbered and/or lettered solely as an aid in readability and understanding. As such, the numbering and lettering in itself is not intended to and should not be taken to indicate the ordering of elements and/or steps in the claims.
