Operations—FIGS. 2A, 2B, 3A, 3B, and others

The system operations of this invention can be basically depicted by these 4 figures, and with some highlighted applications information hereafter depicting the solutions provided by this invention for the mentioned problems that suffered from referred prior art.

(1) FIG. 2A shows how the temperature is being lowered with solar energy, electrical heating element, or both of them being applied. Indoor warm air enters system through the rear end opening of indoor hot air flow channel unit 1901, and passes through indoor hot air flow channel unit 1904, and further passes down to the bottom of the system, then flows up to the zone where solar heating plate 901 is located. The warm air is then being heated up there to be density smaller and therefore generates thermo-siphoning effect and creates air flow driving force to drive the heated air outdoor from top cover openings 1201. As the warm air moving out from indoor, the left behind indoor room is then being supplied with outdoor cool air that entering system from the base openings 706 and the matched front end bottom opening of bi-direction air flow channel unit 2003, and entering indoor through the rear end openings of bi-direction air flow channel unit 2001. This cycle is then going on and makes the temperature lowering and air exchanging possible. Note: Under this operation mode, hot air flow channel unit 1801, Indoor hot air flow channel unit 1904, and bi-direction airflow channel unit 2008 are unit locations in system being moved toward front. This operation mode provides some solutions for the problem 1 and problem 2 that suffered from referred prior art.

Temperature can be lowered optionally with electrical fan being applied alone while electrical heating element is off and solar energy is not available such as it is cloudy or at night time and no thermo-siphoning effect is created. Note: Under this operation mode, hot air flow channel unit 1801 and indoor hot air flow channel unit 1904 are unit locations in system being moved toward front, and bi-direction airflow channel unit 2008 is closed and unit location in system being moved toward rear. This operation mode provides some solutions to the problem 5 suffered from the referred prior art.

Conclusion, Ramifications, and Scopes

Accordingly, the reader will see that the dualpower temperature regulation system of this invention can be installed to window frame or any wall opening of any object or embedded to equipment if it requires the stated functions, such as outdoor chamber for power or telecommunication, grain barn, garage, basement with window or opening above earth ground, gable of penthouse, factory, greenhouse, and any room of building, etc. to utilize free solar energy if the sun beam can reach. It also can be installed to trailer, container, or ship with some modification being applied on such object to fit it on.

Obviously, refer to item 1 and item 2 of Operation section (FIG. 2A and FIG. 2B), this system is working well while it is mounted to the upper portion of indoor for lowering temperature, and working well while it is mounted to the lower portion of indoor for raising temperature, but not so well if it is to be mounted reversely for that purpose per poor indoor heat convection; therefore, an attachment of bi-direction air flow channel extender being attached to system to get better indoor heat convection in spite of where this system is being mounted.

This system can be shut off and no air flowing in between indoor and outdoor while its indoor hot air flow channel units and bi-direction air flow channel unit are closed and are locations in system being moved toward rear, and hot air flow channel unit is opened and is unit location in system being moved toward front in order to meet the situation such as air conditioner is in use or others.

This system can also be used to expel indoor air outdoor without air exchanging with outdoor air by having hot air flow channel unit and indoor hot air flow channel unit to be unit locations in system being moved toward front, and bi-direction air flow channel unit to be location in system being moved to its middle location, the last two units will guide indoor air entering system and exit outdoor through hot air flow channel unit per thermo-siphoning effect. Certainly, we need to replenish air indoor from the other source to keep the air expelling going on, e.g. open indoor interfaced door or window to get air entering from the other indoor room or others.

The fan gate module can be alternatively attached to bezel upside down to guide the fan air flow direction from or to upper portion of indoor in order to enhance the indoor heat convection and system performance, and the fan gate can be opened to any angles (at the range from 0 to 90 degree) to guide air flow direction from or to where it is desired in a single way, and then the fan gate angle can be fixed by screw bolt and wing nut securing.

The bi-direction air flow channel extender can be alternatively installed up side down to match with the rear opening of indoor hot air flow channel to extend the opening to upper portion of indoor while this system is being mounted at the lower potion of indoor.

The air flow velocity can be controlled by offsetting indoor hot air flow channel unit location in system a little toward rear while indoor air is entering system through it, or offsetting bi-direction air flow channel unit location in system a little toward front while indoor air is entering system through it, or outdoor air is entering system through top cover opening to indoor when electrical fan is in use for raising temperature.

This system is not suggested to be mounted to flat or titled roof without any modification being made onto the roof as rains may invade system and indoor, and hot air generated by roof may enter system to indoor while temperature lowering is being desired, a gable being built on such roof is a good way for this application

Although the description above contains many specificities, these should not be construed as limiting of the invention but as merely previous illustrations of some of the presently embodiments of this invention. For example, this invention can be formed the other shape or the other size to meet different requirement, or plurality of electrical fan or electrical heating element can be equipped to system, etc.
