Definitions
- the invention relates to a refrigerator with the in the preamble of claim 1 specified features.
- a cooling device is known from US-A-4,133,652.
- ozone On hot, sunny days, especially in conurbations through interaction of solar radiation with Air pollutants, especially nitrogen oxides, ozone are formed.
- the ozone accumulates in the air we breathe and can close Difficulty breathing.
- closed rooms where even no ozone is formed is the ozone load less because the rooms are isolated from the outside air are.
- the rooms in general then be kept closed when ozone formation is low, namely in the cold season, whereas in the warm season Season in which the ozone formation is strongest, doors and windows be opened so that the outside air enriched with ozone flows in unhindered can.
- the object of the present invention is to reduce the ozone load in clear out and reduce cabins.
- a cooling device with the specified in claim 1
- an ozone catalyst is located in the flow path in front of the refrigerator lies. Only by combining an ozone catalyst with a cooling device it can be ensured that the ozone content in rooms can be kept low, because only if the rooms are supplied with cooled air there is sufficient probability that windows and doors be kept closed or windows can be installed from the outset that cannot be opened. The same applies to automobiles in which In summer there is only an incentive, windows and sunroof closed to hold, or not to provide a sunroof at all, if a pleasant temperature is ensured by cooling instead of draft can be.
- the combination of the cooling device and the ozone catalyst appears therefore as the only sensible way to check the ozone content in rooms and keep cabins low.
- the ozone catalyst is placed in front of the chiller. This has the advantage that relatively warm air is applied to it, which is favorable for the efficiency. It would be different if the catalytic converter were arranged in the flow path behind the chiller: There, the catalytic converter would be undercooled by the cold air flowing past, its conversion rate would decrease and condensation water would form on the catalytic converter, which would lead to a further decrease in the catalytic conversion rate and corrosion problems would entail.
- a dust filter in the flow path in front of the catalytic converter to provide.
- the invention is particularly suitable for automobiles and small air conditioners, such as those used for air conditioning small Find shops and practices.
- catalytically active substance that will split ozone Palladium used, which already without additional heating is sufficiently active.
- the catalytically active substance is superficially on a Anchored support that is permeable to air, e.g. on a ceramic honeycomb body, on a body made of layered Corrugated iron or on crosswise stacked Wire mesh.
- the flow resistance and thus type and The thickness of the carrier must be adapted to the place of use, whereas the inflow surface corresponds to that in the cooling unit available space can be selected.
- you build the gap catalyst in modular design in such a way that you have several flat, one below the other installs beams of the same thickness in a holding frame.
- the carriers which are preferably the same, can then prefabricated for different applications and in Frames are used that are adapted to the purpose are.
- the frame can be a simple one Act lattice structure in which the beams are loose inserted and fixed by a counter frame.
- the carrier has proven to be particularly favorable choose between 10 and 30 mm thick, preferably approx. 15 mm thick. For higher efficiency one can use several arrange such layers of supports one behind the other in a common framework or in separate frameworks, which in turn are combined into a module.
- Figure 1 shows a compact air conditioner with an elongated, cuboid housing 1 with a suction side 2 at one End and an air outlet side 3 at the other end and in between arranged a refrigerator 4, a fan 5, a gap catalyst 6, a dust filter 7 and at the On the outlet side, a blind 8 made of adjustable slats.
- the catalyst 6 is located between the dust filter 7 on the input side and the fan 5, which the Air sucks in through catalyst 6 and over the refrigerator 4 presses. From the intake side 2 coming, still relatively warm and through the dust filter 7 cleaned air flows through the catalyst 6, in which the ozone is converted to oxygen, and is then cooled in the refrigerator 4.
- the catalytic converter 6 is of modular construction manufactured. It consists of a plastic frame 9, in which by cross-arranged webs 11 nine same fields are formed, in which one Catalyst carrier 10 is held. Two such frames 9 are arranged one behind the other and to form the Catalyst 6 summarized.
