Detailed Description
The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. The following description of at least one exemplary embodiment is merely exemplary in nature and is in no way intended to limit the application, its application, or uses. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
Fig. 1 shows a schematic structural diagram of an air outlet component of an air conditioner according to this embodiment, and as shown in fig. 1, the air outlet component of an air conditioner according to this embodiment includes a plenum housing 1 provided with an air outlet and a throttle member 4 covering the air outlet.
The air outlet part of the air conditioner further comprises a heat preservation part 2 arranged on the inner wall or the outer wall of the air chamber shell 1, and the material of the heat preservation part 2 is preferably foam.
The air conditioner outlet assembly further comprises a mounting frame 3 connected to the plenum housing 1, the mounting frame 3 being adapted to be connected to a ceiling to secure the air conditioner outlet assembly to the ceiling.
The air-conditioner air outlet part further comprises an air guiding part 6 arranged for guiding the air outlet direction of the air outlet. Alternatively, the air guiding member 6 is provided outside the throttle member 4.
Fig. 3 shows a schematic structural view of the throttle member 4 of the present embodiment, and fig. 4 shows a partially enlarged view of fig. 3.
As shown in fig. 3 and 4, the throttle member 4 of the present embodiment is provided with a duct 5 communicating with the air outlet, and the inner diameter of at least one section of the duct 5 increases gradually in the air outlet direction of the air outlet.
In this embodiment, the flow area of the duct 5 is smaller than the flow area of the air outlet, after the air outlet of the air outlet is throttled by the duct 5 on the throttle member 4, the pressure of the air is reduced, the volume is increased, the space between the gas molecules in the corresponding air is increased, the potential energy of the gas molecules is increased, the kinetic energy of the gas molecules is correspondingly reduced, and the change of the kinetic energy of the gas molecules macroscopically reflects the change of the temperature, namely the temperature of the throttled air is reduced.
The cross-sectional area of the gas flow increases gradually as the gas flows through the first orifice 51 of the flared structure, according to A 1 V 1 ＝A 2 V 2 =c (wherein a 1 And A 2 Are all the cross-sectional areas of the pore channels, V 1 And V 2 The velocity of the gas, C is a constant), the flow velocity of the gas is reduced more rapidly when the rate of change of the sectional area of the gas flow is large, thereby achieving the effects of stable flow and enhanced comfort.
The duct 5 of the throttling part 4 reduces the air outlet speed, the noise at the air outlet part is reduced, the indoor air flow is uniform in structure, the wind feeling perceived by a human body is reduced, and the indoor comfort is improved.
In this embodiment, the number of the holes 5 is plural, and the plural holes 5 are arranged in a row and a column on the restriction member 4.
Each duct 5 comprises a first duct 51 and a second duct 52 located upstream of the first duct 51 in the air outlet direction, wherein the inner diameter of the first duct 51 increases in the air outlet direction and the inner diameter of the second duct 52 decreases in the air outlet direction.
The duct 5 further comprises a third duct 53 of equal diameter, the third duct 53 being arranged between the first duct 51 and the second duct 52, the first end of the third duct 53 being directly connected to the first duct 51, the second end of the third duct 53 being directly connected to the second duct 52. The third duct 63 may function to buffer the air-out to reduce the impact.
Alternatively, the first duct 51 is located downstream most of the duct 5 in the air-out direction; the second portholes 52 are located furthest upstream of the portholes 5 in the air outlet direction.
The air outputted from the air outlet of the air chamber housing 1 flows through the second duct 52, the third duct 53 and the first duct 51 in this order.
The throttle member 4 includes a plate-like member 41, and the duct 5 extends in the thickness direction of the plate-like member 41.
The throttle member 4 further includes a boss provided on the plate-like member 41, the boss protruding from the plate-like member 41 in the thickness direction of the plate-like member 41, and a part of the cells 5 provided on the boss 5.
The bosses comprise a first boss 42 provided on a first face of the plate-like member 41 and a second boss 43 provided on a second face of the plate-like member 41.
The number of the pore channels 5 is multiple, and the bosses are arranged in one-to-one correspondence with the pore channels 5. The portholes 5 extend from the end face of the respective first boss 42 facing away from the plate-like member 41 to the end face of the second boss 43 facing away from the plate-like member 41.
Since the inner diameter of the second duct 52 is tapered along the air outlet direction, when the air outlet of the air outlet flows through the second duct 52, the speed of the air outlet increases, and thus, phenomena such as vortex and friction are easy to occur when the air outlet flows through the second duct 52.
To overcome the above-mentioned phenomenon, in the present embodiment, the flow rate of the air outlet is increased in the second duct 52, and the pressure is reduced in the first duct 51, so that the pressure difference between the air outlet and the air inlet is increased before and after the air inlet is throttled, to improve the above-mentioned phenomenon. Because the flow rate of the air outlet is high and the time for the air outlet to flow through the throttled duct 5 is short when the air outlet passes through the duct 5, the air outlet is not as fast as the air outlet exchanges heat with the outside, and can be approximately considered as an adiabatic process, that is, the total energy in the air outlet is unchanged.
In this embodiment, the throttle member 4 is added to the air outlet at the end of the air conditioning system, the throttle member 4 includes a plurality of ducts 5 arranged in rows and columns, the ventilation areas at both ends of the ducts 5 are the same, the internal cross-sectional area of the ducts 5 is reduced and then increased, and air is blown into the room.
The air outlet component of the air conditioner enables the temperature of cold air entering the room after throttling to be lower than the temperature in the air duct, namely when the same unit operates and the indoor temperature is set to be the same, the air supply structure of the application enables the time for reducing the indoor temperature to be shorter, and the operation time of the air conditioner to be relatively shorter, thereby improving the refrigeration efficiency, improving the COP of an air conditioning system and achieving the effect of energy conservation; meanwhile, considering that the air supply temperature is too low, when the unit is started and operated, the temperature of the air supply opening is lower than the indoor dew point temperature to form dew, and the throttling structure is reasonably designed to control the refrigerating air quantity, reduce the temperature and the pressure of cold air to reduce, and find the indoor temperature dew point.
According to another aspect of the present application, the present embodiment further discloses an air conditioner, which includes the air conditioner air outlet component described above.
The foregoing is illustrative of the present application and is not to be construed as limiting thereof, but rather, any modification, equivalent replacement, improvement or the like which comes within the spirit and principles of the present application are intended to be included within the scope of the present application.
