Definitions
- the invention relates to an air cooler according to the preamble of claim 1 and a method for cooling the air in rooms, especially in walk-in storage or cold rooms.
- Generic air coolers are, for example. For cooling the air in large-volume rooms, such. B. walk-in storage or cold rooms used.
- the air coolers used for this purpose are part of the equipment of the storage or cooling room and installed in stationary.
- the air cooler contains a heat exchanger, for example in the form of a heat exchanger, on or through which the air to be cooled is passed or passed through, wherein the heat exchanger extracts heat from the air and cools 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 channel 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 outside the space to be cooled, for example.
- a condenser or a recooler On the roof of the building in which the storage or cooling room is located.
- the refrigerant is filled only after the installation of the cooling system, consisting of the arranged in the storage or cooling chamber air cooler and the external condenser or recooler in the condenser or recooler.
- the condenser or recooler is connected via pipelines to the evaporator of the air cooler to direct the refrigerant in the liquid state and at low pressure through the evaporator.
- the evaporator evaporates the first liquid refrigerant and removes the air flowing through heat.
- the vaporized refrigerant is returned via the pipe into the condenser or recooler to be liquefied there by compression or cooled.
- an air conditioner which has a housing which can be installed on a ceiling, in which a radial fan is arranged.
- the centrifugal fan sucks ambient air through one at the bottom of the housing arranged air inlet and blows the sucked air in the radial direction through laterally arranged in the housing air outlets.
- a heat exchanger is arranged in the air outlets through which the air blown out by the centrifugal fan is passed and thereby cooled.
- the radial fan and the heat exchanger are in each case at the same height with the air outlets arranged laterally in the housing.
- Another air conditioner of this type is known from JP 06 137 558 A.
- this air conditioner comprises a housing which can be installed on a ceiling, in which a diagonal fan and a heat exchanger are arranged.
- the diagonal fan sucks in ambient air through a suction opening arranged on the underside of the housing, in which the heat exchanger is arranged.
- the sucked air flows through the areally formed and substantially horizontally lying heat exchanger and is thereby cooled.
- the sucked and cooled air is guided by the diagonal fan obliquely upwards and deflected by means of guide elements obliquely downwards in the direction of laterally arranged in the housing air outlets.
- the cooled air flows through the air outlets back into the room.
- a cooling system for large-volume rooms eg. For walk-in cooling and storage rooms
- a cooling system for large-volume rooms which comprises a arranged in the space to be cooled evaporation device and thus connected via piping external compressor and a downstream condenser, the outside to Cooling space are arranged.
- a refrigerant carried in a piping system is compressed and liquefied in the downstream condenser and then passed in the liquid state through the piping into the evaporator. Before the refrigerant enters the evaporator, the liquid refrigerant flows through an expansion valve to drain the refrigerant.
- the cooling system can be operated either with a single-phase or a two-phase refrigerant, wherein the evaporator arrangement during operation of the system with a single-phase refrigerant acts as a simple heat exchanger and when operating with a two-phase refrigerant as an evaporator in which evaporates the expanded refrigerant through the expansion valve and - After it has been heated by the passing ambient air - passed in 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.
- the housing further comprises a planar and covered by a grille air inlet and a likewise flat trained and covered by a grille air outlet, wherein the air inlet and the air outlet are arranged in opposite walls of the housing and the microchannel evaporator therebetween.
- a plurality of fans are further arranged, which are coupled to the microchannel evaporators to direct air through the evaporator means. For this purpose, ambient air is sucked through the air inlet and blown out of the housing through the air outlet. The ambient air drawn in by the fans is passed or passed through the microchannel evaporators, which cools the air.
- the housing of the evaporator device can be placed in the walk-in storage or cooling room or suspended from the ceiling, so that between the ceiling and the top of the housing remains a free space that allows the inflow or outflow of air.
- the installation of the housing on the bottom of the Lager appears to be cooled.
- the refrigerator requires a lot of space, which is no longer available as a storage room.
- a suspended arrangement of the evaporator device on the ceiling of the accessible storage or cooling space has the disadvantage that dust and dirt can be deposited on the horizontal upper side of the housing on which the air inlet or the air outlet is arranged. This is particularly problematic in storage and cold storage for food, as the stored material can be contaminated, resulting in hygiene problems.
- the invention is based on the object to provide a highly efficient air cooler for cooling the air in large-volume and especially walk-storage or cold rooms, which has a housing which is arranged on a ceiling of the space to be cooled and which the disadvantages of Known in the prior art cooling equipment and in particular the dripping of condensation and the accumulation of dust and dirt on the top of the suspended from the ceiling cooling equipment avoids.
- the air cooler should be space-saving installable in the room to be cooled and in particular be as low as possible to allow installation on the ceiling, without significantly reducing the room height.
- the air cooler comprises a housing with a bottom, a lid which can be fastened directly and without clearance to a ceiling of the space to be cooled and at least one side wall, in which at least one air outlet is arranged, and at least one planar and substantially configured one in the housing horizontally lying heat exchanger and at least one arranged in the housing above the heat exchanger fan.
- the fan sucks ambient air from the space to be cooled through an air inlet and the sucked air flows at least substantially in the vertical direction through the planar heat exchanger and is deflected by the fan in the horizontal direction to the arranged in the side wall of the housing air outlet.
- the fan and the air outlet are above the heat exchanger.
- the sucked air flows through the flat heat exchanger at least substantially perpendicular to its plane and leave the housing through the at least one laterally disposed air outlet and can flow back into the room.
- This will create a large effective heat transfer area and thus ensuring a good heat transfer efficiency.
- 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 lateral air outlet in a substantially horizontal flow direction. This prevents unpleasant vertical air currents in the room to be cooled and allows a uniform 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 allows the arrangement of a pan for collecting condensation, located on the outer surface of the heat exchanger, in particular on the fins and the pipes of a finned heat exchanger or a Mikrokanalverdampers, can form.
- a recess is expediently formed in the bottom of the housing, or it is arranged in the interior of the housing a collecting trough on the floor.
- the condensation which forms on the outer surface of the heat exchanger and drips from there due to gravity, can collect in the depression of the soil or in the arranged on the bottom drip tray and be discharged via a at the lowest point of the depression or the drip tray opening drain line.
- the air inlet through which the ambient air is sucked by the fan into the interior of the housing, is expediently arranged below the heat exchanger and - as the at least one air outlet - in a side wall of the housing. This ensures, on the one hand, that the entire ambient air flowing into the housing is conducted through the heat exchanger, whereby a very efficient heat transfer can be produced.
- 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 provided in the housing.
- the housing may be cylindrical and have a cylinder jacket-shaped side wall.
- the air inlet and the air outlet are expediently arranged alternately and uniformly around the circumference of the side wall of the cylindrical housing.
- the housing may also be formed cuboid with four mutually perpendicular side walls, expediently in the or each side wall, in which an air outlet is provided, no air inlet is arranged, and vice versa. This prevents that already cooled air leaving the housing through an air outlet can be sucked back into the housing directly through an air inlet arranged adjacent to the air outlet.
- a partition plate is preferably arranged, in which an air passage opening is formed.
- the air passage opening in the partition plate is aligned with the fan, ie the air passage opening is coaxial with the axis of rotation of the fan and the diameter of the air passage opening corresponds at least substantially to the diameter of the fan, which is typically in the range of 200 to 400 mm, but also up to 1200 mm can be large.
- the ambient air sucked in laterally from the fan through the air inlet flows into the housing at least substantially in the horizontal direction and is deflected there by the negative pressure generated by the fan in the area above the partition plate in the vertical direction and flows first through the flat heat exchanger and then through the air passage opening in the partition plate in the fan.
- the partition plate divides the interior of the housing in a horizontal plane and ensures that the ambient air sucked in by the fan can flow at least substantially completely in the vertical direction through the heat transfer in a planar manner.
- the heat exchanger can be designed as a microchannel evaporator or, alternatively, as a lamellar heat exchanger, in both cases the air drawn in flows parallel to the lamellae of the heat exchanger or the evaporator, namely in the case of a Lammellen heat exchanger parallel to the fins of the heat exchanger and in the case of a microchannel evaporator parallel to the zig-zag between the parallel microchannels of the microchannel evaporator arranged lamellae. In both cases, the sucked air flows perpendicular to the flow direction of the flowing through the tubes or channels of the heat exchanger refrigerant. This also ensures a large heat transfer surface and thus efficient heat transfer.
