Definitions
- the invention relates to an air conditioner.
- the present invention relates to a filter unit for an air conditioner.
- Air conditioning is a collective expression for conditioning air into a desired state. It could be heating the air during cold periods, cooling the air during warmer periods or for cleaning the air if it contains unwanted particles.
- air conditioners can look and be used in various ways, but they all share the same basic technology.
- the air- conditioner comprises a compressor, a condenser, an evaporator, and typically also an expansion device.
- air-conditioners There are different types of air-conditioners.
- One type of air-conditioner can be referred to as a split air-conditioner.
- the condenser and the evaporator are located in two different separated units that are interconnected via pipes to circulate a refrigerant from one unit to the other.
- Another type of air-conditioner can be referred to as a Packaged Air
- a Packaged Air Conditioner can be said to be a type of self- contained system, in which all the cooling cycle components, such as the compressor, condenser, expansion device, evaporator and control system are enclosed in a single package.
- air-conditioners are provided with an air filter for filtering the air passing through the air conditioner.
- air can be filtered in the indoor part of the air conditioner when the air-conditioner is of a split type.
- the filter is typically located inside or above but before the heat exchanger to collect dust or particles to provide better air quality in the indoor space where the air conditioner is located. While providing for a better air-quality the filter typically also has the negative effect that the air flow rate through the air-conditioner drops and this effects performance of the air-conditioner negatively.
- CN201476182U shows a filter unit that can be attached to an indoor unit of a split air-conditioner.
- conventional air-conditioners are provided with a fixed filter solution that is pre-inserted or installed on the air conditioners.
- the filtering mechanism cannot take into account the variations in air quality, but the filtering provided as constant even though the air quality can shift within a broad range.
- a filtering unit that can change the filtering function by opening or closing the filter unit thereby enabling the filtering to be different at different points in time.
- a filter unit configured to be mounted on an air-conditioner.
- the filter unit comprises a moving part holding at least one filter.
- the moving part is configured to be driven between at least a first position and a second position.
- the filter of the moving part can be driven between a position where air is filtered to a higher degree and a position where air is filtered to a lower degree.
- the filtering can be varied by moving the moving part between the at least first position and second position.
- the at least one filter can be implemented by a filter module placed in the moving part.
- the filter unit in the first position, is configured to be in a completely closed position where all air passing through the filter unit passes through the moving part.
- a mode with a high degree of filtering can be obtained.
- the moving part is configured to rotate between the at least first position and second position.
- an efficient moving mechanism can be provided that is easy to implement and which can move the filter between an open position with no or relatively little air passing through the filter and a closed position with all or relatively much air passing through the filter.
- the moving part is configured to be moved continuously between an open position and a closed position. Hereby only a part of the air through the air-conditioner can be filtered and the other part enter the air-conditioner unfiltered.
- the filter unit is a separate unit having a separate power supply.
- the filter unit can be a stand-alone unit that can be bought and installed separately from the air-conditioner itself. It will then become possible to supplement an existing air-conditioner with a filter unit providing all the benefits provided by the filter unit as described herein.
- a motor is provided in the filter unit for driving the moving part.
- the filter unit can be driven automatically and also there is no need to rely on driving means from an external source.
- a particle sensor and or a gas sensor can be provided in the filter unit.
- the filtering can be made in response to the existing air conditions and filtering need only take place when there is determined to be a need.
- a visual indicator can be used to indicate the air quality.
- the filter unit is configured to set the position of the moving part in response to the output from the particle and or gas sensor.
- a remote-control input configured to receive an input signal to control the position of the moving part.
- a user can set the desired position for the filter unit. For example, a user may want to increase the air-conditioning at the expense of air-quality at some time or vice versa.
- the filter unit is configured to be mounted on the air-inlet of an indoor unit of a split air conditioner.
- the filter unit can be easily mounted on an existing air-conditioner without having to modify the existing air-conditioner.
- the invention also extends to an air conditioner having a filter unit in accordance with the above.
- the air-conditioner can be a split air-conditioner with the filter unit is mounted on the air inlet of the indoor unit of the split air-conditioner.
- Figs la and lb show a general view of an openable filter unit for an air conditioner
- Fig. 2 is a view in perspective illustrating a filter unit mounted on an indoor unit of an air-conditioner
- Fig. 3 is an exploded view of the filter unit depicted in Fig. 2.
- a general view of a filter unit 102 for an air-conditioner is depicted.
- the filtering unit 102 comprises a frame 104 holding the parts of the filter unit 102.
- the filter unit 102 further comprises a moving part 106 comprising at least one air filter 103 and a motor 108 for moving the moving part 106.
- air entering an air conditioner can either, when the moving part is in a first position be forced to pass via the at least one filter 103 of the moving part or, when the moving part is in a second position air can enter, at least partly, the air-conditioner without passing the filter of the moving part 106.
- the air entering the air-conditioner either be made to pass the filter 103 of the filter unit or not.
- the first position can be a completely closed position where all air entering the air-conditioner needs to pass a filter.
- the second position can be a fully open position where no air entering the air conditioner passes through a filter.
- the moving part opens and closes using a rotating mechanism and use existing fan and air flow of split air conditioners.
- the filter unit can comprise filters, a motor such as a step motor.
- a particle matter measuring sensor can be provided to provide input to a controller configured to open and close the filter unit in response to a measured particle matter value.
- the filter unit can in accordance with some embodiments have a remote control that can be used to open and close the filter unit.
- the filters used can be electret and low pressure drop type filters to provide better air purification. When air purification is not needed, the filter unit can open by rotating up and the air conditioner can run on cooling or heating without any performance loss.
- the moving part can be moved continuously between an open position where no air is filtered and a closed position where all air entering the air-conditioner is filtered. In one embodiment the moving part can be placed in any position between the open position and the closed position.
