Definitions

  • the present invention relates to a heat medium storage device. More in particular, the invention relates to safety improvements to heat medium storage devices having heat exchanging elements.
  • EP2080975A1 in the name of ATLANTIC CLIMATISATION ET VENT discloses a device for heat exchange between fluids belonging to two circuits.
  • the device has a reservoir to receive coolant e.g. water, and a coolant inlet equipped at a lower part of the reservoir.
  • a coolant outlet is equipped at an upper part of the reservoir.
  • a coaxial heat pipe is arranged at inside of the reservoir, and is immersed in the coolant.
  • An inner tube of the pipe is connected to the inlet at an end of the reservoir, and opens at another end of the reservoir.
  • the inner tube is provided as a passage for the coolant.
  • An outer tube of the pipe is provided as a passage for refrigerant.
  • EP1965164A1 in name of ATLANTIC CLIMATISATION ET VENT discloses a device for heat exchange between fluids belonging to two circuits.
  • the device has a reservoir to receive coolant fluid.
  • the reservoir is equipped with a coolant fluid inlet arranged in a lower part of the reservoir and an outlet of a coolant fluid arranged in an upper part.
  • An exchanger with coaxial tubes is arranged inside the reservoir, and is immersed in the fluid.
  • An inner tube is connected to the inlet at an end, and is opened in the reservoir at another end.
  • the tube has a section between the inlet and the exchanger, where the section is uncovered by an outer tube in which leakage opening is arranged.
  • US2003196450 in the name of Higami Sadao discloses Refrigerant processing apparatus for collected equipment, and oil separator.
  • the oil separator makes use of a partitioned chamber in order to separate contaminated refrigerant from accumulated oil. While the oil separator allows the separation of a gas and a liquid, the ratios of liquid to gas are substantially different from those in a heat medium tank, thus requiring a substantially different solution.
  • the present invention aims to resolve at least some of the problems and disadvantages mentioned above.
  • the invention thereto aims to provide gas-liquid separator for a heat medium circulation system, said gas-liquid separator having improved gas-liquid separation which prevent the spreading of any leaked refrigerant to any user-side elements e.g., heat exchangers.
  • the present invention thereof serve to provide a solution to one or more of above-mentioned disadvantages.
  • the present invention relates to a gas-liquid separator for heat medium circulation system according to claim 1.
  • the container is further provided with a cylindrical container subpart at the upper part of the container main body and be in fluid communication with the internal space of the container main body.
  • the container subpart has a width smaller than the width of the container main body, when the gas-liquid separator is viewed from above.
  • the internal volume of the container subpart is up to 5% of the volume of the container. More preferably, the internal volume of the container subpart is up to 10%, 15%, 20%, most preferably, 25% of the volume of the container.
  • Refrigerants used in heat pumps, air-conditioning or other similar refrigerant using installations have lower densities than water or other heat mediums with which said refrigerants are expected to exchange heat (e.g. mineral oil).
  • the device of the present invention is particularly suited, though not exclusively, to the use of water as a heat medium.
  • Water has a higher density than refrigerants, even when said refrigerants are compressed above normal operating pressures expected in heat pumps or air conditioning installations.
  • the present invention takes advantage of the difference of density between refrigerant and heat medium, in particular the buoyancy effects produced by said difference. In this way, any refrigerant making its way to the inside of the container along with the heat medium via the first outlet will naturally have the tendency to separate from said heat medium and float upwards and pool over the heat medium.
  • any leaked refrigerant will tend to pool and be retained inside the internal volume of said subpart.
  • the container main body and the container subpart are formed with a cylindrical shape.
  • both of the cylindrical central axes are common.
  • the cylindrical shape and its subpart, as well as their substantial concentricity advantageously allow for easier manufacturing. This configuration is particularly efficient in capturing any leaked refrigerant when the distal end of the heat medium of the heat exchanger is located near the axis of the container subpart.
  • the container main body and the container subpart are formed with a cylindrical shape.
  • both of the cylindrical central axes are offset.
  • the cylindrical shape and its subpart advantageously allow for easier manufacturing. This configuration is particularly efficient in capturing any leaked refrigerant when the distal end of the het medium of the heat exchanger is located near the central axis of the container subpart.
  • the minimal distance between the distal end of the heat medium passage and the central axis of the container subpart is smaller than the minimal distance between the heat medium outlet and the central axis of the container subpart, when the gas-liquid separator is viewed from above.
  • the heat medium outlet is located near a container wall and diametrically opposite to the container subpart.
  • the heat medium outlet is advantageously distanced from any refrigerant coming from either the container subpart or the distal end of the heat medium passage of the heat exchanger, thereby eliminating the risk of refrigerant entering the heat medium outlet.
  • the double tube heat exchanger is formed in a spiral or helical shape, wherein the central axis of the helix or spiral extends in the height direction of the gas-liquid separator.
  • the heat exchanger advantageously has a larger heat exchange area, said heat exchange area being defined by both the inner and outer sides of the refrigerant passage.
  • the larger heat exchange area permits more heat to be exchanged between the refrigerant and the heat medium before the refrigerant returns to the compressor side of the refrigerant circuit.
  • the helical or spiral shape of the internal heat exchanger permits a more efficient use of the internal space of the container, advantageously allowing, for example, for smaller containers to be used.
  • the distal end of the heat medium passage of the heat exchanger is located adjacent and is oriented tangential to a wall of the container main body.
  • the spiral or helical shape of the heat exchanger includes at least two turns, the last of which turns includes the distal end of the heat medium passage of the heat exchanger, the distal end of the heat medium passage being located at least 10mm farther from the axis of the spiral or helix than each preceding turn.
  • heat medium leaving the heat exchanger is advantageously ejected near the inner lateral walls of the container and in a direction that is substantially tangential to said walls.
  • the heat medium outlet is located in substantial overlap with the cylindrical axis of the container main body.
  • the heat medium outlet is shielded by the convection current around the inner and outer perimeter of the heat exchanger which force any leaked refrigerant upwards and away from said outlet. This advantageously makes it impossible for any refrigerant to leave the container via the heat medium outlet.
  • the present invention concerns gas-liquid separator for a heat medium circulation system according to claim 1.
  • the heat medium circulation system comprises of the gas-liquid separator, a pump, a controller that controls at least the pump and a usage-side heat exchanger like a radiator.
  • the gas-liquid separator includes a container having a cylindrical container main body with an internal heat exchanger for exchanging heat between a heat medium and a refrigerant, the passages for each of these fluids being both inside the container and immersed in heat medium.
  • the heat medium passage of the internal heat exchanger, the pump and the usage-side heat exchanger are connected by heat medium pipes, and the heat medium circulates inside the heat medium pipes.
  • the refrigerant passage of the internal heat exchanger, an expansion valve, a heat source-side heat exchanger and a compressor are connected by refrigerant pipes, and the refrigerant circulates inside the refrigerant pipes.
  • propane can be used as a refrigerant.
  • R32 refrigerant can be also used.
  • the heat medium passage includes a first outlet in fluid communication with the internal volume of the container.
  • the container is provided with a cylindrical container subpart connected to the top of said cylindrical container main body.
  • the internal volume of the container subpart is provided in fluid communication with the internal volume of the container main body.
  • the location of the container subpart above the heat medium outlet allows for superior liquid gas separation, as any refrigerant leaking into the container quickly returns to a gaseous state and floats to the top of the internal volume of the container and into the internal volume of the container subpart.
  • the smaller width of the container subpart in combination with the low buoyancy of the refrigerant contribute to trap the latter and prevent it from leaving the container to any user-side elements.
  • the terms "one or more” or “at least one”, such as one or more or at least one member(s) of a group of members, is clear per se, by means of further exemplification, the term encompasses inter alia a reference to any one of said members, or to any two or more of said members, such as, e.g., any ⁇ 3, ⁇ 4, ⁇ 5, ⁇ 6 or ⁇ 7 etc. of said members, and up to all said members.
