With a pump, the heat transfer medium is sucked by the heat generator and then passed from a valve or mixer to the heater or to a hot water tank, where the heat of the heat transfer medium is used.
    From EP 2 226 589 a hot water tank for connection of a hydraulic module is known. At least one hydraulic module is attached to the thermal storage tank for thermal storage loading or storage discharge. Connecting pipes can be connected to the hydraulic connections via threads or quick couplings. Each hydraulic module has at least two passages, which are arranged such that the rear wall of the hydraulic module can be fitted via at least two hydraulic connections or connecting pipes and can be screwed tight by means of nuts.
    From DE 10 2004 040 737, a hydraulic module with a storage container is known. To the hydraulic module, a heating circuit and / or a hot water preparation can be connected.
    A hydraulic module according to DE 10 2012 209 118 comprises a housing and at least two terminals on the housing. At least one connection can be connected to a connection of a neighboring further hydraulic module in such a way that the housing is mechanically connected to a housing of the further hydraulic module.
    A hydraulic module is known from DE 10 2009 048 585, which is equipped with at least one flow connection and at least one first return connection.
    From EP 0 911 590 B1 a unit with an integrated hydraulic distribution is known, in particular suitable for wall-mounted boiler, for heating and generating sanitary hot water. In a valve unit there is a three-way valve which is connected to a hot water supply pipe network, to a consumer of a secondary sanitary hot water circuit and to an outlet of a primary circuit for water. Furthermore, there is provided a vent and pump venting unit which may be connected to an inlet and an outlet of a group of radiators of a heating system and to the inlet of the primary circuit.
    From EP 1 528 329 B1 an assembly for a compact heating system is known. This has a pump housing, wherein the back of the unit a plate heat exchanger is connected. The pump housing projects beyond the plate heat exchanger on one side so that the space above, below or next to the plate heat exchanger is used for the pump housing.
    With the known distribution systems is a heating or heating of a building and a hot water system and a heat distribution and heat transport.
    The object of the invention is to provide a distribution system which allows 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.
    Is the object of the invention with the features of claim 1.
    The hydraulic module has a housing with a substantially 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 pipe is led from the refrigerator to the drying room and the central pipe is in particular largely airtight led 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 led by a first wall into the refrigerator, 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 in the operating position below a second vent, causing air through the first vent into the refrigerator flows in particular when the pump is working and warm, causing a convection and the air from the second vent heats again flows out.
    Advantageously, a distribution device for distributing the heat transfer medium is arranged in the drying room. The central pipe, a hot water supply pipe and a heating supply pipe are connected to the distribution device, wherein the heat transfer medium is directed, in particular, into the hot water supply pipe or the heating supply pipe from the distribution device.
    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 chamber.
    The media connections, the central tube, the hot water supply pipe and / or the heating flow pipe are advantageously at least partially used in the hydraulic module largely airtight, especially with the outside attached to the pipes concerned 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 the transfer of 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. According to the invention, the hydraulic module 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 connected and in particular with a hot water storage. 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 for heating 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 is passed to the hot water system and / or to a hot water tank of the building.
    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 flow heater is formed in the hydraulic module heat. Added to this is the heat carried by the heat transfer medium into the hydraulic module.
    For cooling the internal pump, this is at least partially sealed off from the area of the hot or cold heat transfer medium by insulating walls from the drying room. In the cooling space in which the pump is located, an opening is advantageously 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 on the outside of 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 switch 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 in the top of the control box, the air in the control box heated by the electrical components escapes into the upper region of the control box and is advantageously performed above the end plate to the rear wall of the Ge housing and out. By this measure, the electronic components of the control box are cooled by an air Konvektlonsströmung.
    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 atmospheric conditions, 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 designed to be entirely airtight, in particular by gluing, welding or film sealing of 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 moisture of the air condenses 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 switch 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 is a continued condensation prevented - the device remains inside, especially in the dry room, largely dry.
