Munson [57] ABSTRACT An air conditioning system for an enclosure in which a heat exchange medium flows in a looped pipe along a wall of the enclosure to and from a temperature regulating unit for heating or cooling the heat exchange medium, the return loop of the pipe being enclosed within an air ventilating shaft spaced from said wall and being provided with fins for directing the air downwardly while the other pipe loop is provided with fins for directing the conditioned air upwardly through an operture in the wall.

3 Claims, 4 Drawing Figures CONVECTORS AND TO SYSTEM EMPLOYING SAME BACKGROUND OF THE INVENTION This invention comprises improvements relating to air conditioning systems for an enclosure such as a dwelling.

It is known to arrange elongated horizontally extending convectors in the horizontal parts of a piping system carrying a liquid heating or cooling medium, said convectors comprising in combination a number of parallel and vertically extending sheet metal fins fixed to one or a number of pipes forming a part of said piping system.

When using such convectors for heating air in dwellings, the air close to the floor is caused to flow upwardly between the fins and receive heat from them. The convection currents thus created promotes the mixing and circulation of the heated air thereby to heat all the air within the premises.

The piping system usually includes vertically directed pipes in addition, but such pipes have not previously had convectors connected in them since the fins would then be disposed horizontally and be unable to guide the heated air in a flow directed upwards and thereby create self-circulation of the air in the premises.

The present invention provides, from one aspect, an assemblage of fins and opposite, parallel, elongated, sheet-form side parts for a convector, the fins extending transversely of and between the side parts perpendicular thereto, the fins being all similarly inclined at an acute angle with respect to the lengthwise direction of the side parts.

The present invention also provides a convector comprising a finned pipe wherein the fins extend transversely of and between opposite, parallel, elongated sheet-form side parts perpendicular thereto, the fins being all similarly inclined at an acute angle with respect to the lengthwise direction of the pipe.

The present invention still further provides a convector system comprising a piping system having vertically extending pipe runs including convectors as defined in the immediately preceding paragraph.

BRIEF DESCRIPTION OF THE DRAWING:

FIG. 1 is a diagrammatic view showing a convector system according to the present invention;

FIG. 2 is a diagrammatic view showing a further convector system according to the present invention;

FIG. 3 is a diagrammatic view showing a still further convector system according, to the present invention;

FIG. 4 is a partial perspective view to a larger size and partly broken away showing a convector according to the present invention.

DESCRIPTION OF A SPECIFIC EMBODIMENT Referring to the accompanying drawings, a closed loop piping system is shown which is assumed to include a boiler or refrigerating unit, and for the purposes of the following description hot water circulates through the pipes.

The piping system consists of vertically extending pipe lines 10,10 and horizontally extending pipe lines In the horizontally extending pipes 10", convectors 11, having vertically extending fins 12 are arranged.

Vertically extending convectors 11' are connected in the vertically extending pipe runs 10,10. The convec- LII parts may be in two parts as described in my copending patent application Ser. No. 209,188, filed Dec. 17, 1971, now abandoned whereby the fins and side parts may be assembled about the pipes 10,10 with the pipes already in position. However, the convectors 11' may be assembled separately and installed in the pipes 10,10 in the usual fashion. The assemblage of fins and side parts would be as described in the above identified patent application except only that the fins would be inclined at an acute angle to the lengthwise direction of the elongated side parts.

As shown in FIG. 1, the two vertically extending pipe lines 10,10, are arranged one on each side of windows 14, and convectors 11 having inclined sheet metal fins are arranged one alongside each window. The fins 12' of the convectors 11' on opposite sides of each window are inclined relatively to one another and to direct air upwardly and across the window, as shown by the arrows in the figure. A curtain of heated air thus covers each window, the air moving upwardly and mixing with colder air to be recirculated by the natural convection currents generated in the room.

As shown in FIG. 2, if the two vertically directed pipe lines 10,10 are arranged on the same side of the windows 14, the fins 12' of the convectors 11 are similarly inclined to direct air upwardly across the window.

As shown in FIG. 3, the piping system with the convectors 11 may be arranged in a vertically extending conduit 15 within a wall of a multistorey building to heat rooms 16 bounded on one side by the wall. A vertically extending air ventilation shaft 17 is provided having its upper end connected to an air intake blower 18 and its lower end opening to a boiler room 19, in which a boiler 20 is placed. The pipes 10,10 are connected in a closed loop with the boiler and the return pipe 10 is positioned in the ventilation shaft 17. The wall has apertures 21 opening one into the lower part of each room 16 for the admission of heated air from the conduit 15 and the pipe 10 is disposed adjacent the apertures 21 and has fins 12 directed upwardly towards the walls 16 and the apertures 21. This arrangement of the fins causes the heated air to rise upwardly through the conduit 15 and through the apertures 21 to warm the rooms. The convector fins within the ventilation shaft direct the fresh air downwardly, the air at the same time being heated as it passes over the fins. The convector systems described may be used for cooling the rooms. The air flow will then occur in the opposite direction a liquid cooling medium flowing in the piping system.

What I claim is:

1. An air conditioning system for an enclosure comprising:

a. a looped pipe extending along an apertured wall of the enclosure in which heat exchange medium flows in a circuit to and from a temperature regulating unit;

b. an air ventilating shaft for passing a current of ambient air along said wall and into said enclosure;

c. said ventilating shaft being arranged in heat exchange relationship with the return loop of said 2. An air conditioning system according to claim 1, in which the ventilating shaft forms an enclosure for the return loop of said pipe.

3. An air conditioning system according to claim 2, in which said ventilating shaft and said looped pipe are enclosed within a conduit extending along said apertured wall.

Claims (3)

1. An air conditioning system for an enclosure comprising: a. a looped pipe extending along an apertured wall of the enclosure in which heat exchange medium flows in a circuit to and from a temperature regulating unit; b. an air ventilating shaft for passing a current of ambient air along said wall and into said enclosure; c. said ventilating shaft being arranged in heat exchange relationship with the return loop of said pipe to precondition the air prior to being passed into the enclosure; d. said pipe being provided with one set of inclined convector fins for directing conditioned air upwardly through the apertured wall into the enclosure and with oppositely inclined convector fins for directing the ambient air downwardly through said ventilating shaft.

2. An air conditioning system according to claim 1, in which the ventilating shaft forms an enclosure for the return loop of said pipe.
