Definitions
- the present invention relates to a heating or cooling system for Temperature control of a building or a means of transport with several rooms, the heat transfer elements arranged in the rooms and through which a medium flows having an active heat exchanger the medium tempered to the flow temperature and with a single room a separate one Pump is assigned, which is a heat transfer element located in the room supplied with the medium tempered to the flow temperature.
- Such a system is in the form of a central heating from DE 197 111 78 known.
- this heating system one does not supply centrally as before arranged heating pump the heating water circuit, but individual Radiators are each assigned separate "decentralized" pumps.
- This decentralized pumps take the ones fed by the heat generator Flow lines the amount of heating water currently required.
- Disadvantageous the system shown is that the decentralized pumps from the operation of a Possibly additionally centrally located pump disturbed would.
- a central pump with a large size Delivery rate affect the individual decentralized pumps, so that a unwanted heating water exchange takes place in the respective radiators.
- a complex speed control individual pumps that communicate with each other via data lines should be connected.
- CH 503 233 A discloses the heating circuits of several heating systems on the one hand with several radiator heating circuits on the other hand via one To couple the storage vessel.
- From US 5 060 601A is a heating system with a heat generator circuit and two collectors integrated therein, the collectors having several Radiator heating circuits are connected.
- EP 0 111 838 A2 describes a space heating system with a central one Boiler and several zones known, each zone one Zone pump is assigned.
- the object of the invention is therefore such a system with decentralized pumps Equipped so that trouble-free operation of centrally located and decentralized pumps in a simple and inexpensive way and while ensuring operational safety.
- This task is carried out by a system according to the characteristic features of the Claim 1 solved.
- the idea for the solution of this task according to the invention is a medium receiving closed vessel, the different circuits decoupled from each other.
- the medium in this vessel becomes on the one hand temperature controlled via a circuit leading into the active heat generator, while on the other hand the tempered water via a system of pre and Return lines is passed through heat transfer elements.
- the simple vessel is included an inexpensive and reliable hydraulic switch, from the individual Branch circuits.
- the thermal switch according to the invention in both heating and can also be used in cooling systems, so their use is in one Heating system with a circulating water heater, such as for heating individual apartments in a larger complex, and with individual radiators arranged in the rooms are particularly advantageous.
- a circulating water heater such as for heating individual apartments in a larger complex
- individual radiators arranged in the rooms are particularly advantageous.
- a system can be, for example, a radiator heater or a Underfloor heating can be realized. It branches off from the thermal switch on the one hand the heating circuit leading through the circulating water heater and on the other hand, the hot water circuit supplying the radiators.
- the vessel according to the invention can advantageously be used in conjunction with a Use known wall heaters, as modern wall heaters with separate Pumps with a high flow rate must be equipped to increase throughput due to the very thin pipes in the thermal springs guarantee. Due to the hydraulic switch according to the invention Combination of such a circulation water heater with a decentralized system Pumping enables.
- the vessel according to the invention is a Pressure expansion vessel, in particular a membrane expansion vessel, the on the one hand can compensate for the pressure in the system and on the other hand as Hydraulic switch for the heating water is used.
- this pressure expansion vessel has an inlet or a Drain connection to fill the system with heating water and / or to allow the heating water to drain from the system.
- the vessel serves as an energy store, which is also used other energy sources, such as solar energy or geothermal energy can be.
- the figure shows a heating system for tempering one not closer shown building with two superimposed rooms, being in each room has a heat transfer element in the form of a radiator 1 is arranged.
- the radiators are hot with a flow line 2 Water supplied, which is returned via a return line 3.
- a decentralized pump in the form of an electronic regulated centrifugal pump 4 arranged the amount of in the radiator flowing medium regulated. Via the pumps 4, the hot medium in the Flow line 2 in the direction of arrow A and in the return line 3 in the direction of arrow B promoted.
- the heating of the medium takes place in a Water heater or circulating water heater trained thermal bath 5, in the the water is passed through an internal circuit 6 via a gas burner 7. Inside the thermal bath is a likewise electronically controlled centrifugal pump 8 arranged as a charge pump, the flow of water through the internal Circulation (arrows C, D) guaranteed.
- the internal circuit and the heating circuit are hydraulic Switch connected in the form of a vessel 9 which receives the heating water.
- the hydraulic switch 9 leads to a drain line Flow line 2 and the feed line 13 to the instantaneous water heater and open on the other hand, the return line 3 and the leading the heated water Drain line 14 of the flow heater.
- the inlet and outlet line is also closed a circuit 10 leading hot water storage provided.
- the vessel 9 itself is a pressure expansion vessel with one in the container arranged membrane 11 formed. It also has a nozzle 12, through which the system can be filled with water and via which System can be emptied.
