Definitions

  • the invention relates to an assembly for heating water in a building, in particular a heat pump, wherein the assembly comprises a casing, a housing for a drawer inside the case and a drawer positioned within the housing. Additionally, the invention relates to a heat pump with the housing for a drawer. Also, the invention relates to a drawer for use in a heat pump comprising the housing.
  • Heating of water in buildings may be accomplished by means of a heat pump system.
  • a heat pump system may either be a ground source to water heat pump (GSHP) system or an air source to water heat pump (AWHP) system.
  • GSHP ground source to water heat pump
  • AWHP air source to water heat pump
  • GSHP ground source to water heat pump
  • calories are exchanged between the ground and the water.
  • the calories in the ground may be extracted by capturing calories in a water table or by circulating a water-based circuit in the ground.
  • AWHP calories are exchanged between the air and the water.
  • Heat pump systems may be further divided into so-called 'split' systems or 'monobioc' systems.
  • the hydraulic group may be connected to, or be a part of, a water-based central heating system, a heated domestic water supply system, a water boiler for heating and storing domestic water, or a combination thereof.
  • the hydraulic group may transport the captures calories from within the heat pump system to a water source outside the heat pump system, either directly or indirectly.
  • the refrigerant loop therefore typically comprises a compressor and an expansion valve to allow the refrigerant in the refrigerant loop to compress upstream of one heat exchanger and to expand upstream of the other heat exchanger thereby enabling the heat exchanging circuit to exchange and transfer calories between the outside air and the hydraulic group.
  • the heat exchanging circuit may be split over an outdoor and an indoor unit.
  • the at least one first heat exchanger is present in an outdoor unit an connected to a ground loop capturing calories from a ground source.
  • the at least one first heat exchanger is present in an outdoor unit capturing calories from the air. The calories are then transported via the refrigerant loop, usually crossing a wall of a building, to the at least one second heat exchanger which is present in an indoor unit. This at least one second heat exchanger then transfers the captured calories to a hydraulic group.
  • the indoor unit is separate from the outdoor unit, while the components of the heat exchanging circuit are thus distributed over both the indoor and outdoor unit. Hence, the heat exchanging circuit is split over the outdoor and indoor unit.
  • Leakage is most likely to occur at a joint within the refrigerant loop. At any joint, two parts of the loop come together and have to be connected securely and tightly in order to prevent any leakage.
  • a major potential risk of a bad connection at a joint within the refrigerant loop may occur upon installation or during maintenance of the heat pump system. Especially when handling the heat exchanger circuit as a whole, misalignment of connections can occur upon installing or reinstalling during maintenance. This can lead to bad connections and as such pose a risk of leakage.
  • the heat exchanger circuit comprising the refrigerant loop usually does not require much or any maintenance. Maintenance typically takes place with other parts of the heat pump system such as with the hydraulic group or the electronic system, including sensors and probes. In the situation that the heat exchanger circuit comprising the refrigerant loop requires maintenance, it involves emptying the heat exchanger circuit of its refrigerant, changing the component without polluting the system and refiling it again while ensuring that there are no leaks. When replacing a component, the circuit needs to be brazed using fire to ensure no refrigerant is present anymore. Usually this requires a trained and authorized installer and operator to perform the maintenance. Also, this kind of maintenance can take about approximately one day of maintenance. Thus it is often more worthwhile and safer to replace the entire heat exchanging circuit as a whole.
  • the drawer thereby comprising at least one heat exchanging circuit suitable for an indoor or outdoor unit of a heat pump system.
  • the drawer may be easily installed, removed or replaced upon installation or maintenance without the requirement of assembling, disassembling or reassembling the refrigerant loop as the whole drawer is inserted and removed as one single part of the assembly.
  • a quick and safe insertion, removal and/or replacement of the heat exchanging circuit is provided.
  • the assembly for heating water in a building may be a heat pump or heat pump system such as a GSHP or AWHP system.
  • the assembly comprises a casing of metal, plastic or a combination of both.
  • the casing may hold and protect all functional parts of the heat pump.
  • the casing comprises at least one housing for a drawer.
  • the housing is being fixed inside the casing and has an opening on at least one side for accepting a drawer wherein the opening is situated in at least one side of the casing so that a drawer can be inserted through the casing into the housing.
  • the housing may be made of metal, plastic or a combination of both.
  • Both the first and second connection interface may be, for example, a pipe fitting, or a part thereof, such as a coupling or adaptor. Both connection interfaces may be threaded, comprise at least a part of a quick-release system or a combination thereof. When the connection interfaces is a threaded interface, the connection interface is preferably situated within the casing and behind the housing to allow easy access for an installer or operator to tighten or loosen the threaded connection.
  • the drawer for carrying a heat exchanging circuit may be made of metal, plastic or a combination of both.
  • the drawer may have at least a front panel that, when positioned into the housing, closes off the casing of the assembly for heating water in a building.
  • the drawer may have at least a bottom panel to support the components comprised within the drawer.
  • the drawer has a front panel, a back panel, two side panels, a bottom panel, and a top panel to enclose the entire drawer and prevent access to the components comprised within the drawer.
  • the drawer comprises at least one heat exchanging circuit.
  • a first end of the secondary hydraulic pipe is connected to at least one heat exchanger within the heat exchanging circuit and a second end of the secondary hydraulic pipe is reversibly connected to the second end of the primary hydraulic pipe via the second connection interface when the drawer is positioned within the housing.
  • the drawer preferably does not comprise any hydraulic piping that does not require direct contact with any of the components present within the drawer and preferably the drawer does not comprise any ignition source such as a hot point or electronic device that can create an electrical spark.
  • the casing with the housing including all functional parts may be installed or maintained without the heat exchanging circuit present within the casing and housing. Furthermore, if the second end of the at least one primary hydraulic pipe is part of to the housing, the connection interface at the second end of the primary hydraulic pipe is stabilized which makes it easier for an installer or operator to place or replace the drawer without any misalignment at said connection interface for the hydraulic group.
  • the assembly for heating water in a building may further comprise electrical wiring, in particular power or electrical signal cables for controlling various components or measuring various temperature and/or pressure probes present in the assembly.
  • the electrical wiring may be situated in the casing, the housing and/or the drawer. There may also be an electrical connection interface present between the casing and the drawer or between the housing and the drawer.
  • the housing is sealed along the edges of the housing.
  • the seal along the edges of the housing prevent any refrigerant gas to escape through the housing and into the casing where electrical circuits may be present. As such, the seal acts as another barrier to reduce risk of explosion.
  • the drawer is sealed along the edges of the drawer.
  • the seal along the edges of the drawer prevent any refrigerant gas to escape through the drawing and into the housing and casing where electrical circuits may be present. As such, the seal acts as another barrier to reduce risk of explosion.
  • the drawer further comprises an air duct.
  • the air duct should be positioned below any connection interface to allow any refrigerant gas to escape from the casing before it reaches any of the connection interfaces.
  • the air duct is preferably situated at the bottom half of the drawer. It is also preferred that the air duct is faced outwards and away from the casing to expel and direct the refrigerant gas away from the casing.
  • the opening of the air duct on the outer surface of the drawer comprises a grid or a grille to prevent solid objects entering the air duct from the outside. This prevents, for instance, a user accidentally sticking their finger into the air duct.
  • the drawer further comprises a fan.
  • This fan may assist in expelling the refrigerant gas through the air duct by accelerating the flow of the refrigerant gas out and away from the entire assembly.
  • the fan comprises a brushless motor to reduce any risk of igniting the refrigerant gas through an electric spark.
  • At least one primary hydraulic pipe is arranged.
  • a first end of the primary hydraulic pipe is connected to the outside of the casing.
  • a first connection interface may be present to allow for a reversible connection between the primary hydraulic pipe and one or more external pipes or hoses via the first connection interface.
  • a second end of the primary hydraulic pipe is arranged inside the casing.
  • the second end of the primary hydraulic pipe may be situated closely behind the housing, be part of the housing or extend through the housing.
  • a second connection interface may be present to allow for a reversible connection between the primary hydraulic pipe and a secondary hydraulic pipe situated in a drawer via the second connection interface.
  • Both the first and second connection interface may be, for example, a pipe fitting such as a coupling or adaptor. Both connection interfaces may be threaded, comprise at least a part of a quick-release system or a combination thereof.
  • Such a casing allows for accepting a drawer comprising a heat exchanging circuit and as such allows installation and maintenance of the casing with the housing including all functional parts may be installed or maintained without the heat exchanging circuit present within the casing and housing.
  • a seal is fitted between the housing and the casing.
  • the seal between the housing and the casing prevents direct contact between the panels of the housing and the casing, thereby reducing any vibrations between the housing and the casing.
  • a drawer for an above mentioned assembly and placement in an above mentioned casing with a housing where the drawer comprises at least two heat exchangers, at least a part of a refrigerant loop comprising a compressor, an expansion valve and a refrigerant and the refrigerant loop being connected to the at least two heat exchangers, and at least one secondary hydraulic pipe, wherein a first end of the secondary hydraulic pipe is connected to at least one of the two heat exchangers and wherein a second end of the secondary hydraulic pipe may be reversibly connected to a second end of a primary hydraulic pipe through a connection interface when the drawer is inserted into an assembly for heating water in a building.
  • Such a drawer can be inserted, removed or replaced within an assembly or casing as mentioned above without having to interact with the heat exchanging circuit present in the drawer as the drawer may be taken out as a whole. As such, the joints of the refrigerant loop cannot be misaligned upon installation or maintenance of the assembly or casing mentioned above.
  • the drawer is sealed along the edges of the drawer.
  • the refrigerant gas can be expelled through the air duct.
  • the air duct is preferably situated at the bottom half of the drawer. It is also preferred that, when inserted into a housing inside a casing, the air duct is faced outwards and away from the casing to expel and direct the refrigerant gas away from the casing.
