The invention provides an air conditioning system which comprises an air conditioner indoor unit and an air conditioner outdoor unit.
In the embodiment of the present invention, as shown in fig. 1 to 3, the indoor unit of an air conditioner includes a casing 10, and a cross-flow wind wheel 20, a heat exchanger 30, a water tank 40 and a wet membrane 50 which are respectively installed in the casing 10; the heat exchanger 30 is positioned on the air inlet side of the cross flow wind wheel 20; the water tank 40 is positioned below the cross flow wind wheel 20, the lower end of the wet diaphragm 50 is inserted into the water tank 40, and the upper end of the wet diaphragm extends upwards to the air inlet side of the cross flow wind wheel 20.
In the embodiment of the invention, the indoor unit of the air conditioner can be a vertical wall-mounted unit or a horizontal wall-mounted unit.
The upper end of the wet diaphragm 50 extends upwards to the air inlet side of the cross flow wind wheel 20, and specifically, the upper end of the wet diaphragm 50 extends to a position between the cross flow wind wheel 20 and the heat exchanger 30; alternatively, the wet diaphragm 50 is located on the side of the heat exchanger 30 facing away from the cross-flow wind wheel 20; alternatively, the wet membrane 50 is located below the heat exchanger 30 and is aligned with the heat exchanger 30 in the up-down direction. When the upper end of the wet diaphragm 50 is located between the cross-flow wind wheel 20 and the heat exchanger 30, or the wet diaphragm 50 is located on the side of the heat exchanger 30 away from the cross-flow wind wheel 20, the wet diaphragm 50 may extend upward to the top end of the cross-flow wind wheel 20, so that the wind sucked into the wind channel through the cross-flow wind wheel 20 can pass through the wet diaphragm 50 to take away the moisture in the wet diaphragm 50; of course, the wet diaphragm 50 may also extend only upward to partially overlap with the cross flow wind wheel 20, so as to reduce the shielding of the air inlet side of the cross flow wind wheel 20, and make the cross flow wind wheel 20 smoother when sucking air.
It should be noted that the wet film 50 is a paper sheet with good water absorption, and a plurality of through holes are usually formed on the paper sheet. The wet diaphragm 50 is capable of siphoning water from the tank 40 to the upper portion of the wet diaphragm 50.
According to the technical scheme, the wet diaphragm 50 is arranged on the air inlet side of the cross flow wind wheel 20, the wet diaphragm 50 can absorb water in the water tank 40 to the upper part of the cross flow wind wheel, and when the air conditioning system is started, the cross flow wind wheel 20 can suck air towards the air duct through the wet diaphragm 50 and blow out the air from the air outlet 12. The moisture on the wet diaphragm 50 is evaporated by the wind force, and is blown out from the air outlet 12 along with the air sucked into the air duct, thereby humidifying the indoor space. Meanwhile, because the wet diaphragm 50 is positioned on the air inlet side of the cross flow wind wheel 20 instead of the air outlet side, when moisture on the wet diaphragm 50 is evaporated and brought into the air channel along with the air, the moisture can be mixed in the air channel, so that the rheumatism degree of each part is more uniform, and the comfort level of the air sent out through the air outlet 12 is improved.
In an embodiment, the wet membrane 50 is located below the heat exchanger 30, and an upper end surface of the wet membrane 50 is attached to a lower end surface of the heat exchanger 30. Because the heat exchanger 30 can produce a large amount of comdenstion water in the course of the work, through laminating the terminal surface under the heat exchanger 30 with wet diaphragm 50 up end, the comdenstion water can directly drip on wet diaphragm 50 and be absorbed and utilized by wet diaphragm 50 to avoid the loss of moisture in the indoor air. If the wet diaphragm 50 is not attached to the heat exchanger 30, a gap is formed between the wet diaphragm and the heat exchanger, and the condensed water is influenced by the liquid tension between the wind and the water flow, so that the originally vertical downward flowing direction of the condensed water is changed, and the condensed water is deviated towards the air inlet direction, and the condensed water cannot well drip on the wet diaphragm 50. Therefore, in this embodiment, by attaching the wetted diaphragm 50 to the heat exchanger 30, no gap is formed between the wetted diaphragm 50 and the heat exchanger 30, and the condensed water can flow onto the wetted diaphragm 50 along the space between the fins of the heat exchanger 30, thereby avoiding the above phenomenon.
When the wetted diaphragm 50 is attached to the heat exchanger 30, in order to ensure that the condensed water can be completely dropped onto the wetted diaphragm 50, the condensed water is best utilized, and therefore, the downward orthographic projection of the heat exchanger 30 is completely dropped into the wetted diaphragm 50. In one embodiment, the shape of the wet membrane 50 is preferably matched to the shape of the lower end face of the heat exchanger 30, such that the two form a better interface that prevents the flow of condensate to other components than the wet membrane 50.
In order to effectively utilize the space in the casing 10 and increase the heat exchange area of the heat exchanger 30, in an embodiment, the heat exchanger 30 is bent as a whole, that is, the lower end surface thereof is also bent. The bent heat exchanger 30 has a larger heat exchange area than the flat heat exchanger 30, and can make reasonable use of the space in the casing 10. Correspondingly, the upper end face of the wet diaphragm 50 is also bent, so that the wet diaphragm has a larger water absorption area and can absorb more water.
In another embodiment, the upper end of the wet diaphragm 50 is located between the heat exchanger 30 and the cross-flow wind wheel 20, so that the wind sucked by the cross-flow wind wheel 20 firstly exchanges heat with the heat exchanger 30, then is humidified by the wet diaphragm 50, and finally is blown out from the air outlet 12 to the indoor. In this embodiment, the wet diaphragm 50 is located between the heat exchanger 30 and the cross-flow wind wheel 20, and since the wet diaphragm 50 and the heat exchanger 30 are partially overlapped in the air intake direction, the installation length of the housing 10 can be reduced. In addition, in this embodiment, by adopting the matching of the cross flow wind wheel 20 and the wet diaphragm 50, the wet diaphragm 50 can be arranged along the axial direction of the cross flow wind wheel 20, that is, can extend from one end of the cross flow wind wheel 20 to the other end, the acting area of the wet diaphragm 50 is larger, and the indoor humidification effect is more obvious.
In this embodiment, since the wet diaphragm 50 and the heat exchanger 30 are arranged in a staggered manner, in order to collect and reasonably utilize the condensed water on the heat exchanger 30, a water pan (not shown) is further disposed below the heat exchanger 30, and the indoor unit of the air conditioner further includes a drain pipe, which is respectively communicated with the water pan and the water tank 40, so that the condensed water is drained to the water tank 40 and used for humidifying the wet diaphragm 50.
Preferably, the water inlet end or the water outlet end of the drain pipe is provided with a filter membrane. Since the water flowing through the drain pipe is condensed water formed by the indoor air being condensed while encountering the heat exchanger 30 having a relatively low temperature, and since the indoor air generally contains impurities such as dust, the condensed water is filtered by providing a filtering membrane, and the filtered condensed water flows into the water tank 40 and fills the entire wet membrane 50 by dialysis. Because the condensed water is purified and then vaporized by the cross flow wind wheel 20 and sent to the room again, the air quality is improved and the human health is facilitated.
In the above embodiment, in order to increase the evaporation area of the wet membrane 50, the wet membrane 50 is corrugated, and preferably, the wet membrane is zigzag, so that a larger amount of water can be adsorbed and the amount of humidification can be increased.
The water tank 40 with the connection can be dismantled to the casing 10, so convenience of customers will the water tank 40 is dismantled in order to right the water tank 40 adds water, and simultaneously convenience of customers is right the water tank 40 carries out regular cleaning, prevents that the interior bacterial growing of water tank 40. Specifically, the water tank 40 may be snapped, plugged, etc. with the housing 10.
The air-conditioning indoor unit comprises a controller, wherein the controller is positioned in an electric control box 60, a liquid level detector and a pipeline communicated with an external water supply device, such as a tap water pipe, are arranged in the water tank 40, a switch valve is arranged on the pipeline, the liquid level detector and the switch valve are respectively and electrically connected with the controller, and when the liquid level detector detects that the water level in the water tank 40 drops to a first threshold value, the controller controls the switch valve to be opened so that the external water supply device is communicated with the water tank 40 to add water to the water tank 40; when the liquid level detector detects that the water level in the water tank 40 rises to a second threshold value, the controller controls the switching valve to be closed to cut off the pipeline, so that the external water supply device stops adding water to the water tank 40.
Of course, a humidity sensor may be disposed on the housing 10, the humidity sensor is electrically connected to the controller for detecting the indoor humidity, and when the indoor humidity is lower than a preset value, the controller controls the switch valve to open to fill water into the water tank 40, so that the wet diaphragm 50 can be in contact with the water.
Preferably, the indoor unit of the air conditioner is a vertical wall-mounted unit, and the cross flow wind wheel 20 is vertically arranged. If the indoor unit of the controller is a horizontal wall-mounted unit, and the heat exchanger 30 is located on the air inlet side of the cross-flow wind wheel 20, when the wet diaphragm 50 is attached to the bottom surface of the heat exchanger 30, the common width of the heat exchanger 30 and the wet diaphragm 50 in the vertical direction is wider, and in order to ensure that the heat exchanger 30 and the wet diaphragm 50 can be located in the air inlet range of the cross-flow wind wheel 20, the cross-flow wind wheel 20 needs to be set larger, that is, the cross-flow wind wheel 20 with a larger diameter needs to be adopted inevitably, so that the sizes of the indoor unit of the air conditioner in the vertical and front-back directions are increased, the cost is increased, and the volume of the indoor unit of the air conditioner is also increased obviously. In the embodiment, the indoor unit of the air conditioner is a vertical wall-mounted unit, when the wet diaphragm 50 is attached to the bottom surface of the heat exchanger 30, only the length of the cross-flow wind wheel 20 needs to be extended, that is, only the length of the indoor unit of the air conditioner in the up-down direction needs to be increased, and other dimensions do not need to be changed, so that the volume change is small.
In this embodiment, the housing 10 has an air inlet 11 on the back and an air outlet 12 on the side. The electric control box 60 and the driving motor 70 of the indoor unit of the air conditioner are located at the upper part of the casing 10, so that the electric control box 60 and the motor are far away from the water tank 40 and the condensed water at the lower part, thereby effectively preventing the motor of the electric control box 60 from entering water.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
