Definitions
- the invention relates to a device for connecting a heat exchanger for a hot water withdrawal device in an apartment and possibly a radiator device in the apartment to a district heating network, with a first valve controlled depending on the flow rate of the hot water withdrawal device and one of the temperature of the removed hot water controlled second valve, both of which are arranged between the district heating network and the primary side of the heat exchanger, the secondary side of which is connected to the hot water extraction device.
- the first valve is controlled as a function of a pressure drop at a throttle arranged in the cold water supply line on the secondary side of the heat exchanger.
- the second valve is controlled by a temperature sensor that measures the temperature of the warm
- the aim is to achieve the most accurate possible regulation of the temperature of the hot water withdrawn with a variable flow rate, temperature and pressure difference in the primary circuit and with a variable cold water temperature
- the temperature of the hot water withdrawn via the withdrawal device can be kept as constant as possible for a given withdrawal quantity. Furthermore, the primary flow in the heat exchanger should be based on the current secondary
- the k v value of the temperature-dependent controlled valve makes up a large part of the total k v - Value out, so that the P-range (proportional range) of the temperature-dependent controlled valve must be wide in order to achieve stable (vibration-free) regulation of the temperature of the hot water on the secondary side of the heat exchanger with small quantities withdrawn.
- the invention has for its object to provide a device of the type mentioned, in which the capacity of the district heating network is better utilized and ne precise and stable control of the temperature of the hot water withdrawn is possible in a simple manner.
- this object is achieved in that the first valve and the second valve are connected in parallel. In this way, proportional control of the two valves is achieved depending on the amount withdrawn.
- the parallel connection of the two valves has the advantage that vibrations of the temperature of the hot water withdrawn are avoided with small withdrawal quantities.
- the total k v value corresponds to the sum of the k v value of each individual valve.
- the k v value of the temperature-controlled valve therefore only makes up a small part of the total k v value, so that stable temperature control with a smaller proportional range is possible compared to valves connected in series.
- the use of a first valve which can be controlled as a function of the volume flow of the removal device has the advantage that the primary side flow is quickly adjustable to the current amount of hot water.
- valves connected in series In the case of valves connected in series, one valve alone cannot increase the total flow beyond the limit determined by the smallest valve. Therefore, when the hot water withdrawal is stopped, the first valve, which is controlled as a function of the flow rate of the hot water withdrawal device, blocks the primary-side flow. The temperature-controlled second valve is then ineffective.
- the total flow on the primary side is equal to the sum of the flows through the two valves. Therefore, when the hot water withdrawal is stopped, the first valve controlled depending on the flow rate is blocked, so that the total flow rate is reduced.
- the temperature-controlled valve remains in operation and set so that its sensor temperature corresponds to the desired extraction temperature.
- the heat exchanger and its primary circuit are kept warm so that warm water flows immediately when the tapping device is opened.
- the first valve is a priority valve, via which the radiator device is also connected to the district heating network and which, when hot water is drawn, throttles or blocks the flow of hot water to the radiator device.
- the priority valve is preferably a three-way valve that can be controlled by a membrane as a function of the volume flow of the removal device. at When hot water is drawn, the pressure on one side of the membrane decreases. The supply of hot water from the district heating network in the radiator device is throttled or blocked, so that the capacity of the district heating network for the delivery of hot water on the withdrawal side is better utilized.
- the closure piece of the first valve can be connected to an actuator which, in the event of a pressure drop in a secondary line of the heat exchanger, effects an adjustment of the closure piece.
- the closure piece of the first valve is expediently connected to one side of the membrane in a housing part and the other side of the membrane to a secondary line of the heat exchanger.
- the secondary line, the cold water line of the heat exchanger and the membrane are preferably connected to the closure of a third valve located in the cold water supply line. This increases the life of the membrane.
- the membrane can also be arranged on the hot water side.
- the device can be constructed so that the first valve has an elongated cylindrical housing part in which the closure piece of the first valve is adjustable in the longitudinal direction and at one end of the housing part of the actuator is mounted so that the membrane coaxial with the longitudinal axis of the Housing part of the first valve is arranged that the housing part of the actuator also forms the housing part of the third valve, that transverse to the housing part of the first valve, the housing part of the second valve is attached with an attached temperature controller for actuating the second valve and the temperature sensor of the temperature controller in is in thermal connection with the hot water outlet of the heat exchanger, and that the second valve bridges the inlet of the first valve and its outlet connected to the heat exchanger.
- a housing part of a fourth valve can be attached to and transversely to the housing parts of the first valve and the second valve, which lies on the input side of the first and second valve connected to the input pressure and as a function of a pressure difference between the input pressure and the output side of the first and second valve is controllable.
- a housing part of a differential pressure sensor can be connected to the housing part of the fourth part, which has a membrane connected to the closure piece of the fourth valve, which is exposed on one side to the inlet pressure and on the other side to the outlet pressure of the first and second valves.

- the device 3 contains - also compare FIGS. 2 to 5 - a first valve, here a priority valve 14 in the form of a three-way valve, with an inlet 15 and two outlets 16 and 17. In parallel with the inlet 15 and the outlet 16 of the priority valve 14 there is a second valve 18 with an inlet 19 and an outlet 20.

- the inputs 15 and 19 of the valves 14 and 18 are connected to the input port 12 via a valve 21.
- the outputs 16 and 20 of the valves 14 and 18 are connected to one another and to the output connection 5.
- the device 3 contains a temperature controller 22.
- a temperature sensor 24 which has an expansion material and measures the temperature of the hot water withdrawn at the secondary-side outlet of the heat exchanger 1 and as a function of the degree of expansion of the expansion material controls or adjusts the valve 18 or its closure piece against the force of an adjustable setpoint spring 25 (FIG. 5), that the mass flow of warm water from the district heating network FW through the valve 18 is adjusted so that the temperature at the outlet of the heat exchanger
- the device 3 also contains between the input connection 13, which is connected to the cold water network KW, and the output connection 7, a further valve 26, the valve closure piece 27 of which is connected to an actuator 28 which, in the event of a pressure drop in the secondary line of the heat exchanger 1, here the Cold water supply line 8, an adjustment of the valve closure member 27 causes.

- valve closure piece 32 of the priority valve 14 From one side to the other of the membrane 29 there is a passage through the valve closure piece 27 and the membrane 29.
- the pressure P 2 (see FIG. 4) on the outlet side of the valve 26 drops sharply compared to the pressure ⁇ > ⁇ of the cold water on the inlet side of the valve 26, so that the Actuator 28 blocks the passage from the central inlet 15 of the priority valve 14 to the outlet 17, which is connected to the radiator device 2 via the outlet connection 11, and the passage from the central inlet 15 to the outlet 16, which connects to the primary side of the heat exchanger 1 via the Output connection 5 and the supply line 4 are connected, opens completely.
