DETAILED DESCRIPTION OF THE PROBABLE EMBODIMENT(S)

In this detailed description, heating system is explained with references to examples without forming any restrictive effect in order to make the subject more understandable.

As can be seen in Figure 1 , at least one heater (10) provided in the inventive heating system is associated with at least one secondary heating unit (40), at least one first heat transfer point (11 ) and at least one second heat transfer point (12). The liquid from the heater (10) is sent to the first heat transfer point (11) and the second heat transfer point (12). The fluid passing through the first heat transfer point (11 ) and the second heat transfer point (12) reaches a diverter valve (50). Said diverter valve (50) is configured to send the incoming fluid to the heater (10), the secondary heating unit (40) or both at the same time. At least one pump (60) associated with the heater (10) also circulates the liquid. In the mentioned configuration, the heater (10) can be a gas heater, an electric heater or a heater powered by an alternative energy source. In addition to the first heat transfer point (11 ) and the second heat transfer point (12), there can be more heat transfer points such as the third heat transfer point (13) and the fourth heat transfer point (14). The heat transfer points mentioned are the points where the heat of the hot fluid passing through the heater is transferred to another fluid by any means. For example, heat transfer points can be a liquid tank or plate heat exchanger for domestic use, a central heating installation for use in heating systems, or a heat exchanger for use in heating a pool. The secondary heating unit (40), on the other hand, can be any heat source such as a solar panel, an electric heater, a gas heater or an underground cycle system.

As can be seen in Figures 2 and 3, the diverter valve (50) comprises a body (51 ) and a lid (54) connected to said body (51 ). There is also an inner body (52) positioned within the body (51 ) and an inner lid (53) provided on the inner body (52).

As can be seen in Figure 4, the body (51) in question has a cylindrical inner chamber (511 ). In a possible embodiment, the body (51 ) is provided in the form of a cylindrical shell, open on one side. In other words, the body (51 ) has circular shaped a base (515) and a lateral wall (516) surrounding the base (515). The mentioned lid (54) covers the inner chamber (511 ). The inner chamber (51 1 ) is provided with at least one first inlet (512) and at least one second inlet (513) to allow fluid to enter the inner chamber (511 ). In addition, a first outlet (514) and a second outlet (541 ) are provided for the discharge of liquid from the inner chamber (511 ). In a possible embodiment of the invention, the first inlet (512) and the second inlet (513) are provided on a base side of the housing (51 ). In a possible embodiment, the first inlet (512) and the second inlet (513) are positioned on an axis passing through the center of the base (515). Thus, on either side of the center, the first inlet (512) and the second inlet (513) are positioned at an angle of 180 degrees. In a possible embodiment of the invention, the first outlet (514) is provided in the lateral wall (516) of the body (51 ).

With reference to Figure 5, the lid (54) is provided in harmony with the form of the body (51 ). When the lid (54) is fixed on the body (51 ), it completely covers the body (51 ). The second outlet (541 ) is provided on the lid (54).

As can be seen in Figure 6, the inner body (52) is provided in a similar form to the body (51 ). The inner body (52) is provided in a size that can be accommodated in the inner chamber (511 ). The inner body (52) is provided to be rotatable about a central axis (a) within the inner chamber (511 ). An inner body base opening (521 ) is provided on the side of the inner body (52) facing the base (515) of the body (51 ). In one possible embodiment of the invention, said inner body base opening (521 ) extends at least partially along a line in the form of an arc. In a possible embodiment, the inner body base opening (521 ) extends through a 180 degree angle around the center of the inner body (52). In the aforementioned structure, the distance of the first inlet (512) to the central axis (a) and the distance of the second inlet (513) to the central axis (a) is provided equal to the distance of the inner body base opening (521 ) to the central axis (a).

There are at least two inner body discharge openings (522) provided on the lateral wall of the inner body (52). The aforementioned inner body discharge openings (522) are provided to extend partially along the lateral wall. The inner body discharge openings (522) are provided in such a way that they essentially decrease in width from one end to the other.

As can be seen in Figure 7, the inner lid (53) covering the inner body (52) is essentially provided in a circular shape in line with the form of the inner body (52). There are at least two lid discharge openings (531 ) provided on the inner lid (53). The mentioned lid discharge opening (531 ) extends at least partially on an axis in the form of an arc. The width of the lid discharge opening (531 ) is provided such that it decreases from one end to the other end.

On the other hand, there is a drive shaft (55) which passes through the base (515) of the body (51 ) and is connected to the inner body (52). Said drive shaft (55) is rotated by a drive from a drive element (551 ). Therefore, the inner body (52) rotates in the inner chamber (511 ) together with the drive shaft (55). By rotation of the inner body (52), the fluid can be prevented or ensured from entering the inner body (52) through the first inlet (512) and/or the second inlet (513). In addition, the exit of the fluid from the first outlet (514) and the second outlet (541 ) can be blocked or ensured. In detail, when the inner body base opening (521 ) overlaps one of the first inlet (512) and the second inlet (513) during the rotation of the inner body (52), liquid enters the inner body (52) through the respective inlet. At the same time, if the inner body discharge opening (522) is aligned with the first outlet (514), the liquid is discharged from the first outlet (514). On the other hand, if the lid discharge opening (531 ) is aligned with the second outlet (541 ), liquid is discharged from the second outlet (541 ). In the mentioned structure, one of the first inlet (512) and the second inlet (513) is open and the other is closed. On the other hand, the first outlet (514) and the second outlet (541 ) can be open separately and at the same time.

As can be seen in Figure 8, in the first position, the first inlet (512) is open and the second inlet (514) is closed. Therefore, it is possible for liquid to enter the diverter valve (50) from the line coming from the first heat transfer point (1 1 ). However, it is not possible for the fluid from the first heat transfer point (12) to enter the diverter valve (50). Also at this time, the first outlet (514) is open and the second outlet (541 ) is closed. Therefore, all the fluid passing through the diverter valve (50) is directed to the heater (10) but there is no fluid transfer to the secondary heating unit (40). In this situation, the cycle takes place via the heater (10) - first heat transfer point (1 1 ) - diverter valve (50).

As can be seen in Figure 9, in the second position, the first inlet (512) is open and the second inlet (513) is closed. Therefore, it is possible for liquid to enter the diverter valve (50) from the line coming from the first heat transfer point (11 ). However, it is not possible for the fluid from the first heat transfer point (12) to enter the diverter valve (50). On the other hand, the first exit (514) and the second exit (541 ) are half open at this time. Therefore, liquid is directly supplied to both the heater (10) and the secondary heating unit (40). Therefore, in this case, at least part of the cycle is also supplied with liquid from the secondary heating unit (40). In this situation, the cycle is partly realized via diverter valve (50) - first heat transfer point (11 ) - the heater (10) which is fed by the secondary heating unit (40). Furthermore, thanks to the cross-sections of the inner body discharge opening (522) and the lid discharge opening (531 ), which expand from one end to the other end, the amount of liquid going to the first outlet (514) and the second outlet (541 ) can be changed in the mentioned position. One of the inner body discharge opening (522) and the lid discharge opening (531 ) widens in a clockwise direction the other one narrows. Therefore, during the rotation of the inner body (52), the amount of fluid passing through one of them decreases while that passing through the other increases.

As can be seen in Figure 10, in the third position, the first input (512) is open and the second input (513) is closed. Therefore, it is possible for liquid to enter the diverter valve (50) from the line coming from the first heat transfer point (11 ). However, it is not possible for the fluid from the first heat transfer point (12) to enter the diverter valve (50). Also at this time, the first exit (514) is closed and the second exit (541 ) is open. Therefore, the fluid transfer from the diverter valve (50) to the heater (10) is only via the secondary heating unit (40). In this case, the cycle only takes place via the heater (10) - first heat transfer point (1 1 ) - diverter valve (50) fed by the secondary heating unit (40).

As can be seen in Figure 11 , in the fourth position, the first inlet (512) is closed and the second inlet (513) is open. Therefore, liquid can enter the diverter valve (50) from the first heat transfer point (12), while the line from the first heat transfer point (1 1 ) is closed. Also at this time, the first outlet (514) is open and the second outlet (541 ) is closed. Therefore, all the fluid passing through the diverter valve (50) is directed to the heater (10) but there is no fluid transfer to the secondary heating unit (40). In this cycle, the fluid passing through the heater (10) passes from the first heat transfer point (12) to the diverter valve (50) and from the diverter valve (50) directly to the heater (10).

As can be seen in Figure 12, in the fifth position, the first inlet (512) is closed and the second inlet (513) is open. Therefore, liquid can enter the diverter valve (50) from the line of the first heat transfer point (12), while the line from the first heat transfer point (11 ) is closed. On the other hand, the first outlet (514) and the second outlet (541 ) are half open at this time. Therefore, liquid is supplied to both the direct heater (10) and the secondary heating unit (40). Therefore, in this case, at least part of the cycle is also supplied with liquid from the secondary heating unit (40). In this cycle, the fluid passing through the heater (10) passes through the first heat transfer point (12) to the diverter valve (50) and after passing through the diverter valve (50), some of the fluid is sent directly to the heater (10) and the rest of the fluid is sent to the heater (10) via the secondary heating unit (40). Furthermore, thanks to the cross-sections of the inner body discharge opening (522) and the lid discharge opening (531 ), which expand from one end to the other end, the amount of liquid going to the first outlet (514) and the second outlet (541 ) can be changed in the mentioned position. One of the inner body discharge opening (522) and the lid discharge opening (531 ) widens and the other narrows in a clockwise direction. Therefore, during the rotation of the inner body (52), the amount of fluid passing through one of them decreases while that passing through the other increases.

As can be seen in Figure 13, in the sixth position, the first input (512) is closed and the second input (513) is open. Therefore, liquid can enter the diverter valve (50) from the line of the first heat transfer point (12), while the line from the first heat transfer point (11 ) is closed. Also at this time, the first outlet (514) is closed and the second outlet (541 ) is open. Therefore, the fluid transfer from the diverter valve (50) to the heater (10) is only via the secondary heating unit (40). In this cycle, the fluid passing through the heater (10) is sent directly to the heater (10) via the secondary heating unit (40) after passing through the first heat transfer point (12) line to the diverter valve (50) and through the diverter valve (50).

The aforementioned configurations of the heating system diverter valve (50) enable the realization of all required cycles without the need to use more than one valve and pump (60). In other words, a single diverter valve (50) and a single pump (60) are used to feed the heater (10), either directly or assisted by the secondary heating unit (40), and to send the heated liquid to multiple heat transfer points.

According to the number of heat transfer points in alternative configurations of the inventive heating system, the number of inlets on the body (51 ) and the form and number of inner body base openings (521 ) in the inner body (52) vary.

In another possible embodiment of the invention, the inner body discharge opening (522) and the lid discharge opening (531 ) can be provided in the form of a form with a narrowing cross-section from one end to the other, or in the form of multiple holes of different widths arranged side by side.

In another possible embodiment of the invention, sealing elements are provided between the components of the diverter valve (50) in areas where fluid passage must be prevented.

In another possible embodiment, the diverter valve (50) used in a heating system can also be used in a cooling system. The cooling system in which the said diverter valve (50) is used cannot be considered outside the scope of protection of the invention. The protection scope of the present invention is set forth in the annexed claims and cannot be restricted to the illustrative disclosures given above, under the detailed description. It is because a person skilled in the relevant art can obviously produce similar embodiments in the light of the foregoing disclosures, without departing from the main principles of the present invention.
