The object of the invention is to provide a distribution system which enables the transmission and conduction of a hot and a cold heat transfer medium stable and secure. Hereby cheap costs and a comfortable assembly as well as production are to be realized.

Solved the object of the invention with the features of claim one.

The hydraulic module has a housing with a largely airtight drying space and a cooling space with at least one cooling unit.

The cooling unit is advantageously formed by at least one first ventilation opening in the housing, a cooling wall with cooling fins or with an air opening.

In the hydraulic module pipes are laid according to an advantageous embodiment, wherein a central tube is guided from the refrigerator to the drying room and the central tube is guided in particular largely airtight by a second wall between the refrigerator and the drying room.

The pump is advantageously installed in the cold room, wherein a heat pump flow pipe is sealed guided by a first wall in the cooling space, and the heat pump flow pipe and the central tube are connected to the pump.

According to one aspect of the invention, the first vent is located below a second vent, whereby air flows in through the first vent into the cold room, particularly when the pump is operating and warming, thereby establishing convection and air heated from the second vent again flows out.

Advantageously, a distribution device for distributing the heat transfer medium is arranged in the drying room. To the distributor, the central tube, a hot water supply pipe and a heating flow pipe are connected, wherein the distribution medium, the heat transfer medium in particular in the hot water supply pipe or the heating flow pipe is passed.

According to an advantageous embodiment, a collecting pipe is provided, to which a heating return pipe, a hot water return pipe and a heat pump return pipe are connected. The heat pipe is adapted to direct the heat transfer medium through the heating return pipe and / or the hot water return pipe to the heat pump return pipe.

The hydraulic module is advantageously equipped with a terminal block through which the media connections, in particular the heating return pipe, the hot water return pipe, the heat pump return pipe and the hot water supply pipe and the heating flow pipe are performed.

Advantageously, the terminal block is covered with a lid, so that a largely airtight space is formed, which is closed in particular by a lid and the media connections are sealingly guided by the lid and / or the terminal block.

Advantageously, a control box space is provided in the hydraulic module, which is cooled by a cooling device, in particular by air openings or cooling fins, and in particular forms a cooling space.

The media connections, the central tube, the hot water supply pipe and / or the heating flow pipe are advantageously used in the hydraulic module at least partially largely airtight, in particular with externally mounted around the respective pipes elastic seals.

The hydraulic module is equipped with a first connection for an energy converter, in particular a heat pump and with a second connection for transferring a cool or warm heat transfer medium to a supply network of a building. Electrical components are provided to control a distribution of the heat transfer medium. The hydraulic module according to the invention has a housing which seals off the different functional areas.

The housing advantageously consists of a rear wall and a front. In the exemplary embodiment, a housing made of an insulating or thermal insulation material, advantageously made of expanded polypropylene (EPP) is shown.

The hydraulic module is further advantageously connected via a hot water supply connection and a hot water return connection to a hot water system of the building and in particular connected to a hot water tank. Furthermore, a heating flow connection and a heating return connection are advantageously provided on the hydraulic module in order to connect it to a heating system of the building. The heat generator is advantageously connectable via a flow line and a return line to the hydraulic module.

The heat generator heats the heat transfer medium to heat the building. In a mode of building heating, therefore, the guided through the flow line and return line heat transfer medium from the hydraulic module is distributed to the heating system. Likewise, the heat transfer medium is directed to the heat distribution system of the building when the heat generator a cooled heat transfer medium is provided for cooling the building.

Advantageously, the heat transfer medium is heated or cooled by a heat pump. The heat pump serves as a heat generator and as needed to produce a cooled heat transfer medium, which is distributed from the hydraulic module to the heat distribution system of the building.

In the case of hot water, the heat transfer medium from the hydraulic module to the hot water system and / or to a hot water tank of the building is passed.

Advantageously, the hydraulic module on a water heater or reheater for the heat transfer medium. With the water heater, the heat transfer medium, in particular in addition to the heat output of the heat generator can be heated faster or a temperature increase of the heat transfer medium can be achieved via a temperature achievable by the heat generator.

To control a pump located in the hydraulic module, the valves arranged there and the optional instantaneous water heater, heat is generated in the hydraulic module. Added to this is the heat carried by the heat transfer medium into the hydraulic module.

To cool the internal pump, this is from the range of hot or cold Heat transfer medium at least partially sealed off by insulating walls of the drying room. In the refrigerator, in which the pump is advantageously an opening is provided below, which allows air to enter. In the cooling space in which the pump is located, an opening is provided at the top, which opens into a convection chimney advantageously provided outside the housing. An above-average heating of the electronic components of the pump is prevented by a passing through the openings air convection flow.

For cooling the electronic components of the control box is advantageously integrated separately in the housing. The switch box is sealed off by insulating walls in particular from the drying chamber.

The switch box housing is advantageously led out through the insulating material to the outside and back of the device with a cooling wall. This advantageously made of metal cooling wall is provided with air openings (Hutzen) that allow air to flow into the control box. Advantageous convection openings in the end plate, which is arranged above in the control box, escapes the heated in the control box by the electrical components air in the upper region of the control box and is advantageously performed above the end plate to the rear wall of the housing and out. By this measure, the electronic components of the control box are cooled by an air convection flow.

In the case of a cooling operation in which the heat generator, here advantageously a heat pump, provides a cool heat transfer medium, the passage of air through the drying chamber of the hydraulic module is largely prevented and the drying chamber is largely sealed airtight to the outside. As airtight is considered in the context of the invention that the two housing shells are connected by a groove and a spring and thereby an air exchange, especially at about atmospheric conditions, is largely avoided. There is no absolute airtightness required, so that advantageously a certain pressure equalization between an air pressure in the drying chamber and an external air pressure can take place. However, in another advantageous embodiment, the hydraulic module can also be made completely air-tight, in particular by gluing, welding or film-sealing the housing or the drying space. This avoids that from the environment of the hydraulic module air in the hydraulic module, in particular in the drying room, penetrates and condenses moisture in the air in a cool hydraulic module and accumulates water.

Thus, the at least one cooling space is cooled by the pump of the hydraulic module, in particular in the heating operation of the heat generator. Furthermore, it is advantageous to design the control room as a cold room. The advantageous openings of the at least one cooling space are exposed and it flows here advantageous air through the cooling chamber of the hydraulic module. Advantageously, especially in the cooling mode no flow through the drying chamber with air and thus a continuous condensation is prevented - the device remains inside, especially in the drying room, largely dry.
