Definitions

  • the invention relates to a heat pump coupling frame kit.
  • the invention further relates to a boiler frame kit, a hybrid energy transformation device and an energy system.
  • the invention further relates to the use of such a heat pump coupling frame kit and/or boiler frame kit.
  • the invention further relates to a method of installation a hybrid energy transformation device.
  • Heat pumps become more and more popular for heating and/or cooling of houses, more and more also in addition to a boiler.
  • a heat pump alongside a boiler is referred to as a ‘hybrid heat pump’.
  • this term refers to an energy transfer system that uses a heat pump alongside a further heat source.
  • it describes fitting a heat pump alongside a natural gas, LPG or oil boiler.
  • Systems comprising a common boiler and a common heat pump require additional installation space. This installation space is not always available, in particular in cases where an already existing boiler needs to be replaced.
  • a disadvantage of such known complete hybrid heat pump systems is that the heat pump is directly connected to the central heating load circuit, this leads to highly fluctuating volume flow during operation, which can reduce the service life of a heat pump.
  • the thermostatic radiator valves are constantly active during operation, which changes the volume flow constantly.
  • the heater valves can be opened and closed manually, which also leads to changes in the volume flow. Also, these volume flow changes lead to reduced service life of a heat pump.
  • Commonly known hybrid heat pumps including complete hybrid heat pump products have the further disadvantage that the installation requires an installer who is trained on refrigeration system mechatronics including the required certifications.
  • the parts of the known complete hybrid heat pump products are only accessible during maintenance via the front of the complete hybrid heat pump product. In a limited and poorly accessible installation space, this means that an installer, who needs to access the heat pump has to work at least partially behind the boiler parts, which leads to longer maintenance service times and reduced comfort for the installer.
  • the known complete hybrid heat pump products are complete solutions which do not allow for a constructively easy adaption and optimization of the complete hybrid heat pump product to the respective installation needs, requirements and limitations.
  • EP2484990A2 is directed to providing a boiler assembly which comprises a removable boiler, alleviating the problem of in-situ servicing and maintenance which requires a large selection of spare parts being available and if the repair is a complex one, the household being without water and/or heating for a considerable period of time.

  • the condenser interface comprises connections that enable the interface to be connected to pipework from a renewable energy powered water preheating device such as a water heating solar panel or a ground source heat pump.
  • EP4145058A1 is directed to providing a climate control apparatus that is highly reliable, relatively easy to provide and at competitive costs and which is extremely compact so that it can be installed in an extremely practical manner.
  • EP4145058A1 discloses a climate control apparatus, comprising a boiler assembly and a heat pump, said boiler assembly comprising a boiler structure and an accommodation compartment for an accumulation tank and for a hydraulic separator, said climate control apparatus comprising means for the hydraulic connection of said accumulation tank to said boiler structure and to said heat pump, wherein said accommodation compartment is provided with means for coupling to a wall and is configured to support said boiler structure.
  • EP4145058A1 discloses further in figure 6 that the user devices’ feed flow is connected to the boiler structure and the return flow is connected the accommodation compartment.
  • the central heating circuit of EP4145058A1 is directed through the boiler and thus disadvantageously requires that the boiler always must be turned on to process the fluid for the central heating circuit.

  • the heating fluid of the heat pump is processed through the accumulation tank of EP4145058A1 which is fluidically connected to the boiler of EP4145058A1.
  • the heat pump has a higher volume flow compared to the boiler structure, which requires a balancing of volume flows to ensure that the volume flow of the heat pump is not choked and leads to unwanted stalling of the heat pump. This is mitigated in EP4145058A1 by way of the accumulation tank leading to temperature loss of the heated fluid.
  • the accumulation tank is a buffer tank
  • the heated fluid of the heat pump will be conveyed to the user device through the accumulation tank, and in particular through the boiler structure of EP4145058A1 this leads to a loss of temperature of the heated fluid from the heat pump.
  • the boiler structure leads to additional loss of temperature of the heated fluid from the heat pump until the fluid reaches the user devices, compared to a direct connection of the heat pump to the user devices. This temperature loss can be compared to the temperature loss resulting from conveying the fluid through a second user device.
  • the heat pump flow rate results from the low deltaT between the inlet and outlet of the heat pump.
  • the heat pump thus has a comparatively high flow rate compared to the boiler to deliver the same defined kW output as a boiler which operates at a higher delta T.
  • the boiler requires a lower flow rate to deliver the same defined kW output.
  • a heat pump and a boiler in series as for example disclosed in EP4145058A1 have the disadvantage that this hybrid system in series has to be defined based on a compromise for the overall flow rate.

  • the flow chamber, the return chamber and bypass chamber are configured so that mixing of heat transfer medium in the return chamber with the heat transfer medium in the flow and the bypass chamber is minimized.
  • LIS11300301 B2 discloses as a particularly important advantage of the invention that the manifold is suitable for returning return liquid heat transfer medium to different heat sources at different return heat transfer medium temperatures in order to enable the heat sources to operate at optimum efficiency. Additionally, the manifold creates a neutral point within the hollow interior region thereof for the heat exchange system, whereby the pressures of the heat transfer medium in the heat exchange system are equalized at the neutral point.
  • LIS11300301 B2 discloses in particular in fig. 1 a system with a boiler and a heat pump.
  • the boiler and the heat pump are fluidically connected to pipes that are fluidically connected to a connector of the manifold. Additionally, the heat pump is fluidically connected to a connector of the manifold. This leads to that the distributor does not separate the boiler fluid flow from the heat pump fluid flow so that there is a mixing of the two fluid flows.
