Definitions

  • the present invention relates to a condenser for a split system air conditioner.
  • Domestic split system air conditioners have an evaporator that is to be installed inside a space of a building to be cooled/heated, and condenser that is to be installed outside the building. Refrigerant is circulated through pipes that connect the evaporator and condenser to transfer thermal energy between the two units in order to provide hot/cold air to the space within the building.
  • the condenser and evaporator are ideally mounted in close proximity. Accordingly, the condenser is mounted on the ground, wall or roof close to the evaporator.
  • Known condensers have a box shaped housing that contains tubes through which refrigerant is passed, fins connected to the tubes, and an axial fan to induce a flow of ambient air through the fins to promote heat transfer from the refrigerant to the air flow.
  • a compressor can also be contained in the housing.
  • a common form of condenser is constructed such that the air flows through the housing in direction that is generally perpendicularly to the major (rectangular) faces of the housing. This requires that there be space between the major faces of the housing and any nearby structures, such as a building wall. For this reason, this form of condenser has an effective footprint that is larger than the actual footprint of the housing, which in itself is relatively large. In certain situations, the condenser significantly impedes the usable space within which it is installed.

  • the tube is located within the constricted region.
  • at least some of the tube is located adjacent the constricted region.
  • the tube is located upstream or downstream of the constricted region.
  • the condenser may further comprise one or more flow modifiers located in the duct to direct the air flow around the fan.
  • the condenser may further comprise a compressor that is in fluid communication with the tube, and the refrigerant inlet.

  • a housing defining first and second ducts through which to pass air
  • first cross flow fan for inducing an air flow through the first duct
  • second cross flow fan for inducing an air flow through the second duct

  • At least one first tube through which to pass a refrigerant the first tube being connected to the first refrigerant inlet and the first refrigerant outlet, at least part of the first tube being located in the first duct to enable heat transfer between the refrigerant and the induced air flow in the first duct;
  • the second tube through which to pass a refrigerant, the second tube being connected to the second refrigerant inlet and the second refrigerant outlet, at least part of the second tube being located in the second duct to enable heat transfer between the refrigerant and the induced air flow in the second duct;
  • each of the first and second ducts has a width to height ratio that is no greater than 8: 1, and wherein the housing includes a common wall that separates the first and second ducts.
  • the first and second ducts are at least partially longitudinally spaced apart relative to the induced air flows.
  • the cross sections of the first and second ducts, perpendicular to the respective induced air flows, may overlap one another.

  • the condenser assembly may be arranged with the first and second outlets located on opposing sides of the transverse central section.
  • the condenser assembly may be arranged with the first and second inlets located on opposing sides of the transverse central section.

L'invention porte sur un condenseur pour un climatiseur à système divisé domestique qui comprend un évaporateur. Le condenseur a un boîtier définissant un conduit à travers lequel doit passer de l'air, et un ventilateur à écoulement transversal pour induire un écoulement d'air à travers le conduit. Une entrée de réfrigérant reçoit un réfrigérant à partir de l'évaporateur, et une sortie de réfrigérant renvoie le réfrigérant à l'évaporateur. Au moins un tube à travers lequel doit passer un réfrigérant est relié à l'entrée de réfrigérant et à la sortie de réfrigérant. Au moins une partie du tube est disposée dans le conduit de façon à permettre un transfert de chaleur entre le réfrigérant et l'écoulement d'air induit. Le conduit a un rapport largeur sur hauteur qui n'est pas supérieur à 8:1.
