The air conditioner in this application performs a refrigeration cycle of the air conditioner by using a compressor, a condenser, an expansion valve, and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies a refrigerant to the air that has been conditioned and heat exchanged.
The compressor compresses a refrigerant gas in a high-temperature and high-pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process.
The expansion valve expands the liquid-phase refrigerant in a high-temperature and high-pressure state condensed in the condenser into a low-pressure liquid-phase refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator may achieve a cooling effect by exchanging heat with a material to be cooled using latent heat of evaporation of a refrigerant. The air conditioner may adjust the temperature of the indoor space throughout the cycle.
An outdoor unit of an air conditioner refers to a portion of a refrigeration cycle including a compressor and an outdoor heat exchanger, an indoor unit of the air conditioner includes an indoor heat exchanger, and an expansion valve may be provided in the indoor unit or the outdoor unit.
The indoor heat exchanger and the outdoor heat exchanger function as a condenser or an evaporator. When the indoor heat exchanger is used as a condenser, the air conditioner is used as a heater of a heating mode, and when the indoor heat exchanger is used as an evaporator, the air conditioner is used as a cooler of a cooling mode.
Fig. 1 shows a circuit configuration of an air conditioner 1, and the air conditioner 1 includes a refrigerant circuit 10, and is capable of performing a vapor compression refrigeration cycle by circulating a refrigerant in the refrigerant circuit 10. The indoor unit 3 and the outdoor unit 2 are connected to each other by a connection pipe 4 to form a refrigerant circuit 10 through which a refrigerant circulates. The refrigerant circuit 10 includes a compressor 11, an outdoor heat exchanger 13, an expansion valve 14, a receiver 15, and an indoor heat exchanger 16. The indoor heat exchanger 16 and the outdoor heat exchanger 13, among others, function as a condenser or an evaporator. The compressor 11 sucks in refrigerant from the suction port, and discharges the refrigerant compressed therein to the indoor heat exchanger 16 from the discharge port. The compressor 11 is an inverter compressor of variable capacity that performs rotational speed control based on an inverter, and the four-way valve 12 switches between heating and cooling.
The outdoor heat exchanger 13 has a first inlet and outlet for passing the refrigerant between the outdoor heat exchanger and the suction port of the compressor 11 via the accumulator 15, and has a second inlet and outlet for passing the refrigerant between the outdoor heat exchanger and the expansion valve 14. The outdoor heat exchanger 13 exchanges heat between the outdoor air and the refrigerant flowing through a heat transfer tube (not shown) connected between the second inlet and the first inlet of the outdoor heat exchanger 13.
The expansion valve 14 is disposed between the outdoor heat exchanger 13 and the indoor heat exchanger 16. The expansion valve 14 has a function of expanding and decompressing the refrigerant flowing between the outdoor heat exchanger 13 and the indoor heat exchanger 16. The expansion valve 14 is configured to be capable of changing the opening degree, and the opening degree is reduced to increase the flow resistance of the refrigerant passing through the expansion valve 14, and the opening degree is increased to decrease the flow resistance of the refrigerant passing through the expansion valve 14. The expansion valve 14 expands and decompresses the refrigerant flowing from the indoor heat exchanger 16 to the outdoor heat exchanger 13 during the heating operation. Further, even if the state of other devices mounted in the refrigerant circuit 10 does not change, when the opening degree of the expansion valve 14 changes, the flow rate of the refrigerant flowing in the refrigerant circuit 10 changes.
The indoor heat exchanger 16 has a second inlet and outlet for allowing the liquid refrigerant to flow between the expansion valve 14 and a first inlet and outlet for allowing the gas refrigerant to flow between the gas refrigerant and the discharge port of the compressor 11. The indoor heat exchanger 16 exchanges heat between the indoor air and the refrigerant flowing through the heat transfer tube connected between the second inlet and the first inlet of the indoor heat exchanger 16.
A receiver 15 is disposed between the outdoor heat exchanger 13 and the suction port of the compressor 11. In the accumulator 15, the refrigerant flowing from the outdoor heat exchanger 13 to the compressor 11 is separated into a gas refrigerant and a liquid refrigerant. The gas refrigerant is mainly supplied from the accumulator 15 to the suction port of the compressor 11.
The outdoor unit 2 further includes an outdoor fan 21, and the outdoor fan 21 generates an airflow of the outdoor air passing through the outdoor heat exchanger 13 to promote heat exchange between the refrigerant flowing through the heat transfer tubes and the outdoor air. The outdoor fan 21 is driven by an outdoor fan motor 21A capable of changing the rotational speed. The indoor unit 3 further includes an indoor fan 31, and the indoor fan 31 generates an airflow of the indoor air passing through the indoor heat exchanger 16 to promote heat exchange between the indoor air and the refrigerant flowing through the heat transfer pipe. The indoor fan 31 is driven by an indoor fan motor 31A capable of changing the rotational speed.
The embodiment of the invention provides an air conditioner, which comprises a rotary air outlet component, wherein the air outlet component is used for realizing 360 degrees of air sweeping angle, the azimuth of the central line of an air outlet is used for replacing the azimuth of the air outlet of the air conditioner, and the air conditioner controller can calculate and record the azimuth of the air outlet when the air outlet is used for 360 degrees of air sweeping. Thus, when the air conditioner receives a command of the target air outlet direction input by a user, the controller rotates the air outlet to the target air outlet direction according to the command.
The rotary air outlet assembly comprises a grating fluted disc, a photoelectric switch and an air outlet, wherein grating teeth are formed on the grating fluted disc, the grating teeth are distributed along the circumference, and the center of the distributed circumference coincides with or is coaxial with the rotation center of the air outlet of the air conditioner. The grating fluted disc and the air outlet of the air conditioner are driven by the driving mechanism to rotate around the same rotation center. The grating fluted disc is provided with a zero point, the position of the center line of the air outlet when the zero point is aligned with the center of the photoelectric switch is a zero point position, and the zero point position corresponds to the position right in front of the shell of the indoor heat exchanger of the air conditioner.
The grating teeth intermittently shield the photoelectric switch to generate a series of pulse signals with a certain pulse width. And calculating the rotation angle of the air outlet according to the number of the pulse signals, and further calculating the air outlet azimuth of the air outlet.
As shown in fig. 2, the rotary air outlet assembly can rotate around the rotation center relative to the whole air conditioner under the drive of the driving mechanism. Thus, the air outlet can rotate for sweeping air by 360 degrees, and the user is provided with a 360-degree rotating wind sweeping range. In the scheme of the invention, the position of the central line of the air outlet is used for replacing the position of the air outlet. The air outlet component comprises a grating fluted disc, a photoelectric switch and an air outlet. The grating fluted disc is fixed relative to the air outlet, and the grating fluted disc and the air outlet are driven by the driving mechanism to rotate around the same rotation center.
As shown in FIG. 3, when the center line of the air outlet is 0 DEG, the air outlet is positioned at the center of the front view of the casing, and the zero point of the corresponding grating fluted disc is at the zero point. When the air outlet rotates, the included angle b between the center line and the 0-degree line can represent the direction of the air outlet. The center line of the air outlet is arranged on the right side of the 0-degree line, and the included angle is a positive value; the center line of the air outlet is arranged at the left side of the 0-degree line, and the included angle is a negative value. Namely, 180 degrees is larger than 0 degrees when the air outlet is on the right side; i.e. 0 DEG > b > -180 DEG when the air outlet is on the left side. The tuyere orientation can be determined by determining the included angle b.
As shown in fig. 3 and 4, the grating tooth plate is formed with grating teeth having a certain width, thickness and height along a circumference (the circumference is concentric with the rotation center) at intervals. When the zero point of the grating fluted disc is aligned with the center of the photoelectric switch, the air outlet is positioned at the right-looking middle position of the shell, namely the center line of the air outlet is positioned at the 0-degree line position. The boundary passes through the zero point and the rotation center, the boundary is taken as the boundary, and the grating tooth size at one side is as follows: the width (arc length) is L4, and the interval (arc length) is L3; grating tooth size on the other side: the width (arc length) is L1 and the interval (arc length) is L2. It is important to note that a gap L0 is formed between two sizes of grating teeth, and the center of the gap coincides with the zero point position. And the interval L0 must be different from L3 and L2 (difference 0.5mm or more).
As shown in fig. 5, the grating teeth intermittently shield the photoelectric switch, and a series of pulse signals with a certain pulse width are generated. The grating teeth produce a high level signal 1 and the grating spacing produces a low level signal 0. Because the air outlet rotates at a constant speed, the signal pulse width is proportional to the grating tooth width and the interval width. For example, the interval L0 corresponds to a pulse width w. The rotation angle can be calculated every time the grating tooth disc rotates by 1 grating tooth or interval. Taking the grating tooth rotated by the arc length L1 as an example, every time 1 grating tooth is rotated by L1, the air outlet rotates by an angle a1= (l1×360°)/M. The circumference length M is the circumference length of the circle where the circular arc L1 is located. Corresponding a0, a2, a3 and a4 can also be calculated. Meanwhile, when the central line of the air outlet is positioned in a certain azimuth, in the signal time domain diagram, the number of pulse widths (namely the number of rotated grating teeth or intervals) relative to the boundary line (zero position) at the moment can be calculated and stored as a preset relation table by the air conditioner controller, and the table is shown as follows:
