Based on this, the object of the invention is to provide a hydraulic module, which is connectable to a heat generator and a distribution system of a building and is also suitable for cooling purposes.

The problem is solved by the features of claim one.

A home automation device is equipped with a first connection for an energy converter 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. According to the invention, the building services equipment has a housing with at least one first opening, wherein a closure element that can be actuated depending on a parameter is attached to the opening. As a result, the electrical components are ventilated in the building services equipment.

Advantageously, the building services device has at least one second opening, which is equipped in particular with a closure element.

According to a further advantageous embodiment, a thermosensible actuator acts on the at least one closure element and the thermosensitive actuator moves depending on the parameter, which is a first temperature.

A thermosensitive actuator is advantageously a shape memory actuator or a bimetallic actuator.

The thermosensible actuator is in particular designed so that the closure element moves above the first temperature and lifts off from the sealing seat.

The building services equipment is advantageously characterized in that the closure element by the thermosensible actuator above the first temperature, with a rising above the first temperature second temperature, further apart from the sealing seat and in particular an opening cross-section depending on the second temperature is free.

The first temperature is advantageously between about 20 ° C and 80 ° C, in particular between about 30 ° C and 60 ° C or more precisely at about 35 ° C to 50 ° C.

According to an advantageous concept of the invention, the closure element is connected to a restoring spring, wherein the restoring spring applies a force F _R against a force F _{A of} the thermosensitive actuator, in particular a thermosensitive actuator made of a memory material, in order to close the closure element again when the temperature falls below the first temperature shut down. The force F _R is at the first temperature advantageously between about 20 ° C and 80 ° C, in particular between about 30 ° C and 60 ° C or more precisely at about 35 ° C to 50 ° C greater than or equal to the force F _A.

It is also advantageous that a bias of the spring is predetermined, which must be overcome by the thermosensitive actuator, so that the closure element lifts from the sealing seat.

The domestic appliance is also 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 is advantageously provided on the building services equipment to connect it to a heating system of the building. The heat generator is advantageous via a flow line and a return line connected to the building services equipment.

The heat generator heats the heat transfer medium for heating the building. In a mode of building heating, therefore, the guided through the supply line and return line heat transfer medium is distributed from the home automation device to the heating system. Likewise, the heat transfer medium is directed to the heat distribution system when provided by the heat generator, a cooled heat transfer medium 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 at the same time to produce a cooled heat transfer medium, which is distributed by the building services equipment on the heat distribution system of the building.

In the case of hot water preparation, the heat transfer medium flow is routed from the domestic appliance to the hot water system and / or hot water storage of the building.

Advantageously, the domestic appliance on a water heater or reheater for the heat transfer medium. With the water heater, the heat transfer medium can be heated for a faster or a temperature increase of the heat transfer medium can be achieved.

For controlling a pump located in the domestic appliance, the valves arranged there and the optional instantaneous heater, heat is generated in the domestic appliance. Added to this is the heat carried by the heat transfer medium into the building services equipment. In the case of high temperatures in building services equipment, the at least one actuator is acted upon by the temperature in the building services equipment. The actuator is advantageously arranged inside in the housing or in the building services equipment to detect the air temperature inside. As the temperature rises, the actuator is also subjected to an increasing temperature. At the first temperature, the closure element is moved by the actuator in such a way that at least one gap forms between the valve flap and a sealing seat. With a further increasing temperature, this gap between the closure element and the sealing seat is getting larger and thus also the opening cross-section. Through the resulting opening cross-section or through the opening, air can now flow into the building services equipment and, in particular, cool and / or dry the electrical components.

For better flow through the HVAC device with air advantageously at least two openings are provided with a closure element. Particularly advantageously, an opening with a closure element is arranged in the bottom of the building services equipment and a second opening with a closure element in an upper region, so that convection of air through the building services device results, the ambient air of the domestic appliance, which is in particular cooler than those located in the home appliance device Air, flows through the first opening in the lower area in the building services equipment and exits through the advantageously arranged in the upper region second closure element warm air from the building services equipment.

In the case of a cooling operation in which the heat generator, here advantageously a heat pump, supplies a cool heat transfer medium, the passage of air through the building services equipment is prevented. In cooling mode, the building services equipment inside is cooled by the flowing cool heat transfer medium. As a result, the actuator or the actuators is also exposed to the cool air present in the domestic appliance, so that the actuators are subjected to a temperature which is advantageously below the first temperature, whereby the actuators pull the closure element onto the sealing seat, so that the openings are substantially closed are. This prevents air from entering the HVAC device from the environment of the HVAC device and condenses moisture in the air in the cool HVAC device and accumulates water.

Thus, the building services equipment is cooled on the one hand, especially in the heating mode of the heat generator. The openings are exposed and air flows through the building services equipment. On the other hand, a flow of air is avoided in the cooling mode and thus prevents continued condensation - the device remains largely dry inside.

The figures show as follows:

1 shows a heat generator, in particular a heat pump.

2 shows a closed valve cap with a shape memory actuator.

3 shows an open valve flap with a shape memory actuator.

4 shows a closure element with a bimetallic actuator in the open state.

5 shows a closure element with a bimetallic actuator in the closed state.

6 + 7 show a closure element with a bimetal in the closed state.

8th + 9 show a closure element with a bimetal in the open state.

1 shows that in buildings 1 located heat generator 2 , which in the exemplary embodiment is advantageously a heat pump. With the heat pump, a cooling operation and a heating operation is possible as needed. A heat transfer medium is through a flow 670 to the home automation device 100 guided. In the home automation device 100 a distribution of the heat transfer medium to a heating flow pipe 640 or to a hot water supply connection 630 , The heat transfer medium then flows through a hot water supply network of the building and then via a hot water outlet connection 631 back to the domestic appliance and from there via the return line 671 back to the heat generator 2 , In the case of heating or cooling of the building, the heat transfer medium flows from the building services equipment 100 first into the heating supply pipe 640 and then into the distribution system of the building 1 , The heat transfer medium then flows through the heating return connection 641 via the home automation device 100 to the heat generator 2 ,

The home automation device consists of a housing 200 of which in the 1 the front 210 , the lid 250 as well as the sidewall on the left 230 can be seen. The side wall 230 know an opening 940 on. Furthermore, there is an opening 940 in the lid 250 arranged.

In 2 is an opening 940 in a partially illustrated cover 250 a housing 200 of the home appliance device 100 shown. In the opening is a valve housing 902 arranged, which a footbridge 904 in which a guide pin 926 is arranged coaxially movable. To the guide pin 926 is a return spring 925 attached, which preferably with a bias between the web 904 and a stop 905 sits and the closure element 910 against a sealing seat 903 suppressed. The system of the closure element 910 and seal seat 903 is shown here in a closed state, in which the closure element 910 on the seal seat 903 rests, so that essentially no air through the opening 940 can flow.

In 3 the system is shown in an open state. The closure element 910 is from the sealing seat 903 lifted and it is an opening cross-section 941 between the closure element 910 and the seal seat 903 formed, causing air through the opening 940 in the home automation device 100 can flow. A shape memory factor 924 has detected a temperature above a first temperature or is of a temperature corresponding to at least a first temperature or above, applied and has turned into an expanded state and thus has the closure element 910 from the seal seat 903 lifted and the spring force of the return spring 925 overcome. A shape memory factor 924 , here in the form of a spiral spring, lies on the jetty 904 at. Opposite is the return spring 925 at the jetty 904 at.

4 shows an opening 940 in which the closure element 910 lifted off the sealing seat 903 is. A bimetallic actuator 922 has the closure element 910 by overcoming the force F _{R of} the return spring 925 lifted. The return spring 925 is thus compressed and the bimetallic actuator 922 has expanded. According to 4 consists of the bimetallic actuator 922 from a kind of accordion, which is acted upon by a first or second temperature of the internal air of the device.

In 5 is the same system as in 4 , only with a bimetallic actuator 922 in the closed state. In particular, in a cooling operation, the system should be closed to the influx of moist air and the condensation of moisture inside the building services equipment 100 to avoid. The bimetallic actuator 922 is subjected to a temperature which is lower than the first temperature and thus the force F _{A of} the bimetallic actuator 922 less than the force F _{R of} the return spring 925 ,

6 and 7 show a closed closure element, which consists of two bimetallic actuators 922 is moved. The temperature of the air inside the building services equipment 100 is below a first temperature and the bimetallic actuators 922 are configured such that they the closure element 910 against the seal seat 903 Press so that the system is closed.

In the 8th and 9 is the system with the bimetallic actuators 922 opened, as the temperature inside the home appliance 100 is higher than the first temperature.

A thermosensible actuator is thus a shape memory actuator 924 or a bimetallic actuator 922 ,
