More preferably, a filtering component can be arranged at the position to ensure that the air sent to the indoor through the other air outlet meets the health requirement of the user.
The heat exchanger is in a conventional system that treats the ambient indoor air entering the cavity, while the fresh air system 130 treats the ambient outdoor air entering the cavity. The two combines effectively to solve the dirty problem of indoor ambient air, promotes the air supply quality of air conditioner, and the high-efficient air that purifies sends to indoor improves user's use travelling comfort.
Specifically, the fresh air system 130 realizes a fresh air function, and can provide fresh air indoors without windowing and air exchange. The fresh air of the nature can be enjoyed without opening the window, the health requirement of the human body is met, and the energy loss is reduced. Can also effectively remove mould and peculiar smell, discharge the damp and dirty air in the room, eliminate peculiar smell, prevent mould and breed bacteria, and is beneficial to prolonging the service life of buildings and furniture. And the noise pollution is reduced, the disturbance of a window opening belt is not needed to be endured, and the indoor environment is quieter and more comfortable. Can also expel harmful gases, effectively expel various unhealthy or harmful gases such as formaldehyde, oil smoke peculiar smell, carbon dioxide, cigarette smell, bacteria, virus and the like, and can avoid the family from being deeply harmed. Avoid windowing and bring a large amount of dust, effective filter chamber outside air, guarantee the air of entering room clean. The fresh air system 130 can also reduce energy consumption while adjusting the room temperature. Avoiding windowing can also avoid the potential safety hazards of property and personal caused by windowing.
The wall-mounted air conditioner indoor unit 100 may further be provided with a carbon dioxide sensor for detecting the concentration of carbon dioxide. The concentration of carbon dioxide in buildings can have a significant impact on the health of people living and working in them, as even small levels of carbon dioxide, e.g., over 1200PPM indoors, can cause yawning and drowsiness.
Therefore, it becomes necessary to monitor the concentration of carbon dioxide. In some specific embodiments, an infrared carbon dioxide sensor, a catalytic carbon dioxide sensor, or a thermally conductive carbon dioxide sensor may be employed. The infrared carbon dioxide sensor detects carbon dioxide existing in the air by utilizing a non-dispersive infrared (NDIR) principle, and has good selectivity and no oxygen dependence. The catalytic carbon dioxide sensor converts the carbon dioxide concentration detected on site into a standard current signal and outputs the standard current signal. The heat conduction carbon dioxide sensor is manufactured according to the principle that the total heat conductivity coefficient of mixed gas changes along with the content of gas to be analyzed, two arms of a bridge are formed by matching a detection element and a compensation element, the resistance of the detection element is reduced when the detection element meets combustible gas, the resistance of the detection element is increased when the detection element meets non-combustible gas (air background), the bridge circuit outputs voltage variable, the voltage variable is increased in direct proportion along with the increase of the gas concentration, and the compensation element has the functions of reference and temperature compensation. It should be noted that the above-mentioned types of carbon dioxide sensors are merely exemplary, and are not intended to limit the present invention, and in other embodiments, other types of carbon dioxide sensors may be used.
The wall-mounted air conditioner indoor unit 100 of the present embodiment includes: a housing 110, a cavity being defined in the housing 110, a first fresh air outlet 111 being formed at the top of the housing 110, and a second fresh air outlet being formed at the bottom of the housing; and a fresh air system 130 disposed in the cavity, configured to allow air of an outdoor environment to enter the cavity, and blown out through the first fresh air outlet 111 and the second fresh air outlet and the air intake assembly 140, connected to the fresh air system 130, and including a fresh air pipe 141 that penetrates a wall drilling hole, and the cross section of the fresh air pipe 141 is crescent-shaped. The air inlet area is increased through the special-shaped fresh air pipe 141, the fresh air quantity is increased, and the quick-change fresh air speed is increased; fresh air system 130 realizes the new trend function, effectively solves the dirty problem of indoor ambient air, promotes the air supply quality of air conditioner, and the high-efficient air that purifies to send to indoor improves the user and uses the travelling comfort.
Further, in the wall-mounted air conditioner indoor unit 100 of the present embodiment, the first fresh air outlet 111 is provided with the baffle plate 121 configured to rotate outwards or inwards around the horizontal shaft 123 to open the first fresh air outlet 111, so as to simplify the structure and improve the air volume. The top of the volute 132 is provided with a first air outlet 136 corresponding to the first fresh air outlet 111, the bottom of the volute is provided with a second air outlet 137 corresponding to the second fresh air outlet, and by arranging the two air outlets, the two air outlets simultaneously discharge air, so that the air volume is large; the two air outlets reduce the resistance of a single air outlet, particularly the resistance when the outlet is connected with an air outlet duct, and the power consumption is effectively reduced; because the multi-outlet fan 135 consumes less power and the fan rotates at a lower speed when the same air volume is provided, the noise of the fan 135 is also lower, and the noise is effectively reduced. The fresh air system 130 further includes: the dust filter 134 is arranged in the first cavity and used for filtering air entering the outdoor environment of the first cavity, so that air supply quality can be further improved, and user experience is improved.
