Definitions
- the invention relates to the design of a hydraulic module for heating systems with a heat transfer medium closed-circuit heat pump.
- Heat pumps use heat from the surrounding environment - from the ground, from ground water or from the air and provide heat for residential space heating and domestic hot water preparation throughout the year. They significantly reduce the cost of energy consumption, they are a substitute for fossil fuel burning and significantly help to reduce carbon dioxide emissions.
- a closed circuit filled with refrigerant is the basis of a heat pump.
- the heat pump, or cooling circuit has four basic parts - an evaporator, a compressor, a condenser and an expansion valve.
- the energy supplied to the condenser is transferred to the circulating heat transfer medium, which is the secondary side of the heat pump.
- the heat transferred from the condenser thus primarily heats the heat transfer medium.
- the heat exchanger of the heat pump can be located in the external unit of the heat pump or in the internal part of the system.
- the heat is further transferred by the heat transfer medium via the hydraulic module.
- Hydraulic modules for heat pump heating systems must meet in particular the following criteria:
- the hydraulic module should also be compact, its dimensions should take up as little space in the system as possible.
- Conventional hydraulic modules for heat pump heating systems are assembled from individual separate components, connected by other parts, mainly pipes and connectors. Such a hydraulic module may be too large and, especially due to the requirement for reheating, together with an electric heater they take up a considerable amount of space in the heating system.
- Document WO2018202436A1 discloses a structural unit for a hydraulic module consisting of three separately made structural connection components, which are preferably made of injection moulded plastic composite materials.
- the inlet structural component is used to connect the inlet of domestic and heating water to the hydraulic module, and the outlet structural component is used for the outlet of the heated domestic and heating water, and they are connected by a plate exchanger to each other.
- the connection sockets located on the individual structural components are used to connect other functional elements of the hydraulic module, such as valves, sensors, an expansion tank, etc.
- the inlet structural components are connected to the circulating pump structural component and to the plate exchanger.
- the location of the circulating pump structural component in the hydraulic module assembly ensures the smallest dimensions of the entire hydraulic module while meeting the hydraulic displacement requirements of the hydraulic module.
- This hydraulic unit does not meet the requirements for a hydraulic module for a heat pump system, as it does not provide reheating, which is needed, for example, in the event of increased heat demand at the outlet or to support the air/water heat pump at very low ambient temperatures.
- reheating which is needed, for example, in the event of increased heat demand at the outlet or to support the air/water heat pump at very low ambient temperatures.
- a separate electric heater must be connected to the circuit for reheating.
- a heat pump with a hydraulic module made of a housing having at least the first wall and the second wall, each of which are injection moulded, is published in the EP2312224B1 document.
- the first and second walls are made of plastic and are joined together, mainly by welding, such as vibration welding, ultrasonic welding, friction welding or laser welding.
- the cavity is partly formed by the walls of the hydraulic module and the fluid pipe connection is provided with a flow connection and a reverse connection. Further cavities of the compact module are described, an additional electric heater being incorporated into one cavity at least in the preferred design.
- the disadvantage of the described hydraulic module is the fact that limescale builds up, especially on the heating elements, during the heating of water, and thus solid impurities can form and accumulate in the cavity, which can be the cause of serious malfunctions in the heating system.
- the hydraulic module does not provide the possibility of filtering impurities.
- EP3816521 A1 describes a hydraulic assembly for a heat pump for space heating and domestic hot water production, which comprises many functions, including filtering of magnetic impurities and the circulation pump body.
- the disadvantage of this solution is that it contains only a common filtering device and the body of the circulation pump is not sufficiently protected against magnetic impurities.
- the positions of the magnets should be closer to the circulating pump, but at a distance that does not affect the proper function of the electric motor. Additionally, the hydraulic assembly is too complex.
- an electric water heater with an integrated solid impurity and magnetic impurity separator with one common drain valve is provided in the document EP3910260 A1 .
- This electric water heater can be used in any system with a closed circuit of a heating medium, then there is no need to incorporate an autonomous filter in the circuit. It conveniently integrates a filter for solid impurities where limescale builds up, i.e. near the heating coils. However, the location of the magnetic filter in the electric water heater is not ideal due to the greater distance from the circulating pump in the heating system.
- Document EP0874201 A2 discloses a construction unit for a compact heating installation, in particular for a gas-fired heating system with two heating circuits, with a centrifugal pump assembly and with an air separator, wherein the air separator is arranged above one another in a common housing which is aligned essentially vertically and is arranged transversely to the impeller axis of the centrifugal pump assembly. In such as arrangement is not possible to separate magnetic particles and compact heating installations does not provide additional heating.
- Document WO2019/190326 A2 describes a removal device for removing dirt particles and/or gas bubbles from a liquid in a liquid conduit system.
- the removal device always provides a supply channel and a return channel, thereby allowing the liquid to flow through the removal device from the entry to the exit.
- the possibility of internal or external magnet for metal dirt is also described.
- Document DE 102018 006784 A1 relates to a pump group for a heating system, having a housing with a carrier plate and a pipeline structure which is arranged on the carrier plate and has a pump train with a pump a return train and system connections for the fluid-tight integration of the pump group into a heating circuit.
- At least one particle separator for separating sludge and magnetite is arranged along the pipeline structure arranged on the carrier plate.
- the installation of a particle separator may involve problems, since additional installation space in the existing pipeline system of a heating circuit has to be made available for this installation, which is difficult in particular in older heating systems, since installation of additional elements in the pipeline system was originally not intended.
- the present invention eliminates the shortcomings of the solutions known in the state of the art and discloses a compact hydraulic module for a heat pump heating system, designed to circulate a heat transfer medium in at least one closed circuit, which provides reheating, integrates the function of a cyclonic filter for solid impurities and a magnetic separator for metallic impurities, and provides all the required functions, the components of the hydraulic module being connected via connectors and formed channels, without the use of connection tubes and extra lines.
- a tank for circulation, filtration and reheating of the heat transfer medium is the basic structural unit of the hydraulic module.
- the tank is made up of an upper part and a lower part, which are connected watertight to each other by bolts and seals or weld, and during operation the hydraulic module is placed in an upright position.
- Both parts of the tank are preferably made of composite materials by injection moulding. Using the mould the technology allows the integration of additional connection channels, chambers, cavities and connectors for the hydraulic module components in both parts of the tank, so the tank is also a connection point for the hydraulic module components, thus eliminating the need for additional pipe connections.
- the upper part of the tank is provided with a cover and a concentric inner wall
- the lower part of the tank is provided with a cover with a conical shape in at least one area.
- two separate circulation channels are defined in the upper part the tank - an outer circulation channel and an inner circulation channel.
- the heating elements of the electric heating block are arranged in the internal circulation channel for heat transfer medium reheating.
- the flow through the tank of the hydraulic module is ensured by the upper part of the tank being hydraulically connected to the heat exchanger of the heat pump and the heat transfer medium being directed through the connection channel to the internal circulation channel defined by the concentric wall.
- the circulation of the heat transfer medium in the hydraulic circuit is provided by a circulating pump, which is arranged in the lower part of the tank and its outlet is hydraulically connected to the heat exchanger of the heat pump and the inlet is hydraulically connected to a 3/2 - way switch valve.
- the heat transfer medium is reheated by means of an electric heating block.
- the heated heat transfer medium is directed into an external circulation channel in the upper part of the tank, into which connection channels for the heat transfer medium outlet to the circuits of the heating system for heating and for domestic hot water preparation are integrated.
- the concentric wall arrangement in the upper part of the tank helps to change the direction and velocity of the flow of the heat transfer medium as it moves through the inner circulation channel from top to bottom and the outer circulation channel from bottom to top.
- the barrier formed by the concentric wall and the heating elements helps to separate solid impurities from the flow of the heat transfer medium, which are deposited by gravity in the conical area of the lower part of the tank, from where they are removed by a drain valve.
- Autonomous cyclone filters for solid impurities work on the same principle.
- any impurities scaled off are removed close to where they originated and are not further transferred into the heat transfer medium circuit.
- the design of the lower tank of the hydraulic module allows the magnetic separator to separate magnetic impurities that may enter the heat transfer medium circuit, for example from radiators, and thus protect in particular the circulating pump, but also other components of the hydraulic module from damage.
- the hydraulic module includes connecting channels, chambers and connectors for a 3/2 - way valve for switching the circuits, a pressure relief valve, circulating pump, magnet, temperature sensor, drain valve for solid impurity removal and drain valve for magnetic impurity removal, bleed valve and connectors for their connection as well as connectors for connecting the hydraulic module to the circuits for heating water, domestic water and heat pump heat exchanger.
- a hydraulic module 100 for heating systems with a heat pump and with at least one heating water circuit and/or a domestic hot water preparation circuit, with a closed circuit of a heat transfer medium, comprises a tank for providing circulation, filtration and reheating of the heat transfer medium, the tank being hydraulically connectable to the heat exchanger 7 of the heat pump, to the heating circuit and/or to the domestic hot water preparation circuit.

- the lower part of the tank 30 comprises a conical area 60 for trapping the solid impurities separated from the flow of the heat transfer medium.
- the concentric wall 40 is designed to separate solid impurities from the flow of the heat transfer medium.
- a body 6 of the circulating pump for circulating the heat transfer medium is formed in the lower part 30 of the tank.

- An electric heating block 9 for heat transfer medium reheating is mounted on the flange to the upper part 20 of the tank by a flange 50 and is arranged in the internal circulation channel 70.
- a bleed valve 8 is attachable to the flange 50 via a connector, which is positioned uppermost within the hydraulic module 100 during operation.
- the upper part 20 of the tank is provided with a connector 7b for the inlet of the heat transfer medium from the heat exchanger 7 of the heat pump to the hydraulic module 100 (the heat exchanger 7 is not a part of the hydraulic module 100).
