Definitions

  • the invention relates to an air cooler according to the preamble of claim 1 and a method for cooling the air in rooms, in particular in walk-in storage or cooling rooms.
  • Air coolers of the generic type are used, for example, to cool the air in large-volume rooms, such as, for. B. walk-in storage or cold rooms.
  • the air coolers used for this purpose are part of the equipment in the storage or cooling room and are installed in a stationary position.
  • the air cooler contains a heat exchanger, for example in the form of a heat exchanger, to or through which the air to be cooled is passed or passed, the heat exchanger extracting heat from the air and cooling it.
  • the heat exchanger can be a heat exchanger which has a pipe or channel system through which a coolant or refrigerant flows.
  • the heat exchanger can also be an evaporator which has a pipe or duct system through which a two-phase refrigerant flows.
  • the pipe or channel system of the evaporator is coupled to a condenser or a recooler, which is regularly arranged outside the room to be cooled, for example on the roof of the building in which the storage or cooling room is located.
  • the refrigerant is only filled into the condenser or recooler after the installation of the cooling system, consisting of the air cooler arranged in the storage or cooling room and the external condenser or recooler.
  • the condenser or recooler is connected to the evaporator of the air cooler via pipes in order to conduct the refrigerant through the evaporator in the liquid state and under low pressure.
  • the liquid refrigerant When the evaporator evaporates the room air to be cooled through the evaporator, the liquid refrigerant initially evaporates and extracts heat from the air flowing through it. The evaporated refrigerant is returned to the condenser or recooler via the pipeline in order to be liquefied or cooled there by compression.
  • a generic air cooler for ceiling mounting is from the EP 1 726 890 A1 known.
  • an air conditioner which has a housing which can be installed on a ceiling and in which a radial fan is arranged.
  • the Radial fan sucks in ambient air through an air inlet arranged on the underside of the housing and blows out the sucked-in air in the radial direction through air outlets arranged laterally in the housing.
  • a heat exchanger is arranged in each of the air outlets, through which the air blown out by the radial fan is guided and thereby cooled.
  • the radial fan and the heat exchanger are each at the same height with the air outlets arranged laterally in the housing.
  • This air conditioning unit also comprises a housing that can be installed on a ceiling and in which a diagonal fan and a heat exchanger are arranged.
  • the diagonal fan draws ambient air through a suction opening arranged on the underside of the housing, in which the heat exchanger is arranged.
  • the sucked-in air flows through the flat and essentially horizontal heat exchanger and is cooled down in the process.
  • the sucked-in and cooled air is directed diagonally upwards by the diagonal fan and deflected diagonally downwards by means of guide elements in the direction of air outlets arranged laterally in the housing.
  • the cooled air flows back into the room through the air outlets.
  • a cooling system for large-volume rooms for example for walk-in cooling and storage rooms, which has an evaporation device arranged in the room to be cooled and a pipe connected to it includes external compressor and a downstream condenser, which are arranged outside the room to be cooled.
  • external compressor a refrigerant conducted in a pipeline system is compressed and liquefied in the downstream condenser and then passed in a liquid state through the pipelines into the evaporation device. Before the refrigerant enters the evaporator, the liquid refrigerant flows through an expansion valve to release the refrigerant.
  • the cooling system can be operated with either a single-phase or a two-phase refrigerant, the evaporator arrangement acting as a simple heat exchanger when operating the system with a single-phase refrigerant and as an evaporator when operating with a two-phase refrigerant, in which the refrigerant expanded by the expansion valve evaporates and - After it has been heated by the ambient air flowing past - in a gaseous state through the pipes back to the compressor and liquefied there again.
  • the evaporator device comprises a housing in which two microchannel evaporators are arranged.
  • a flat air inlet covered by an air grille and an air outlet which is also flat and covered by an air grille are arranged in the housing, the air inlet and the air outlet being arranged in opposite walls of the housing and the microchannel evaporators lying between them.
  • several fans are arranged in the housing, which are coupled to the microchannel evaporators in order to conduct air through the evaporator device.
  • ambient air is drawn in through the air inlet and blown out of the housing through the air outlet.
  • the ambient air drawn in by the fans is directed past or through the microchannel evaporators, causing the air to cool down.
  • the housing of the evaporator device can be set up in the walk-in storage or cooling room or be suspended from the ceiling, so that a space remains between the ceiling and the top of the housing, which allows air to flow in or out.
  • Setting up the housing on the floor of the storage or cooling space to be cooled requires a lot of space that is no longer available as a storage space.
  • a suspended arrangement of the evaporator device on the ceiling of the walk-in storage or cooling room has the disadvantage that dust and dirt can be deposited on the horizontal top of the housing on which the air inlet or air outlet is arranged. This is particularly problematic in storage and cooling rooms for food, since the stored goods can become soiled, which causes hygiene problems result.
  • the condensed water which is deposited on the pipes and the fins of the microchannel evaporator, can drip out through the air outlet (or the air inlet).
  • the object of the invention is to provide a highly efficient air cooler for cooling the air in large-volume and in particular walk-in storage or cooling rooms, which has a housing which is arranged on a ceiling of the room to be cooled and which has the disadvantages mentioned known cooling devices and in particular the dripping of condensation and the accumulation of dust and dirt on the top of the cooling devices suspended from the ceiling.
  • the air cooler should be able to be installed in a space-saving manner in the room to be cooled and in particular should be as low as possible in order to enable installation on the ceiling without significantly reducing the room height.
  • the air cooler comprises a housing with a base, a cover which can be fastened directly and without a distance to a ceiling of the room to be cooled and at least one side wall in which at least one air outlet is arranged, and at least one which is arranged and essentially flat in the housing horizontally located heat exchanger and at least one fan arranged in the housing above the heat exchanger.
  • the fan draws ambient air from the space to be cooled through an air inlet and the sucked-in air flows at least essentially in a vertical direction through the flat heat exchanger and is deflected by the fan in a horizontal direction to the air outlet arranged in the side wall of the housing.
  • the fan and the air outlet are located above the heat exchanger.
  • This arrangement enables the sucked-in air to flow through the flat heat exchanger at least substantially perpendicular to its plane and to leave the housing through the at least one laterally arranged air outlet and into the Space can flow back. This ensures a large effective heat transfer area and thus good heat transfer efficiency. Furthermore, a vertical air flow of the cooled air from the housing into the space to be cooled is prevented because the cooled air leaves the housing through the at least one side air outlet in a substantially horizontal flow direction. This prevents unpleasant vertical air flows in the room to be cooled and enables an even distribution of the cooled air in the room.
  • the inventive arrangement of the fan, the at least one air outlet and the heat exchanger in the housing of the air cooler also enables the arrangement of a trough for collecting condensed water, which is located on the outer surface of the heat exchanger, in particular on the fins and the pipes of a finned heat exchanger or a microchannel evaporator.
  • a recess is expediently formed in the bottom of the housing, or a collecting trough is arranged on the bottom in the interior of the housing.
  • the condensed water that forms on the outer surface of the heat exchanger and drips from there due to gravity can collect in the recess in the floor or in the collecting trough arranged on the floor and can be discharged via a drain line that opens at the lowest point of the recess or the collecting trough.
  • the air inlet through which the ambient air is sucked into the interior of the housing by the fan is expediently arranged below the heat exchanger and - like the at least one air outlet - in a side wall of the housing. This ensures, on the one hand, that all the ambient air flowing into the housing is passed through the heat exchanger, as a result of which very efficient heat transfer can be generated.
  • the arrangement of the at least one air inlet in a side wall of the housing prevents unpleasant air flows in the space to be cooled in the vertical direction.
  • Several air inlets and several air outlets are expediently provided in the housing.
  • the housing can be cylindrical and have a cylinder wall-shaped side wall.
  • the housing can also have a cuboid shape with four mutually perpendicular side walls, wherein no air inlet is expediently arranged in the or each side wall in which an air outlet is provided, and vice versa. This prevents air that has already been cooled and leaves the housing through an air outlet from being drawn back into the housing directly through an air inlet arranged adjacent to the air outlet.
  • a separating plate in which an air passage opening is formed, is preferably arranged between the flat heat exchanger and at least substantially in a horizontal plane and the fan.
  • the air passage opening in the separating plate is aligned with the fan, i.e. the air passage opening runs coaxially with the axis of rotation of the fan and the diameter of the air passage opening corresponds at least essentially to the diameter of the fan, which is typically in the range from 200 to 400 mm, but also up to 1200 mm can be large.
  • the ambient air sucked in laterally by the fan through the air inlet flows at least essentially in a horizontal direction into the housing and is deflected there in a vertical direction by the negative pressure generated by the fan in the area above the separating plate and initially flows through the flat heat exchanger and then through the air passage opening in the partition plate into the fan.
  • the separating plate divides the interior of the housing into a horizontal plane and ensures that the ambient air sucked in by the fan can flow at least essentially completely in the vertical direction through the flat heat transfer.
  • the subdivision of the interior of the housing by means of the separating plate ensures decoupling of the flow of the sucked-in ambient air in the vertical direction by the heat exchanger and the outflow of the cooled air in an at least substantially horizontal flow direction through the at least one air outlet. This can cause air turbulence inside the Housing and consequently a reduction in heat transfer efficiency can be avoided.
  • the heat exchanger can as in the US 2006/0130517 A1 be designed as a micro-channel evaporator or alternatively as a finned heat exchanger.
  • the sucked-in air flows parallel to the fins of the heat exchanger or evaporator, namely in the case of a finned heat exchanger parallel to the fins of the heat exchanger and in the case of a microchannel evaporator parallel to the zigzag between the parallel microchannels of the micro-channel evaporator arranged fins.
  • the sucked-in air flows perpendicular to the flow direction of the refrigerant flowing through the pipes or channels of the heat exchanger. This also ensures a large heat transfer area and thus efficient heat transfer.
  • the illustrated embodiment of an air cooler for cooling the air in large-volume rooms, in particular in walk-in storage or cooling rooms or cooled work rooms comprises a cuboid housing 1 with a horizontally lying floor 1a, a parallel and spaced apart lid 1b and four side walls 1c perpendicular to each other and to the bottom or lid.
