The condensation can cause the phenomena of water dripping, small water drops blowing and the like of the air conditioner, and the user experience is influenced. When the refrigerating effect is strong, the air conditioner is easy to generate condensation phenomenon, and when the refrigerating effect is insufficient, the user feels uncomfortable.

However, in the type having a plurality of positions for the up-down wind sweeping and the left-right wind sweeping, the air output of the air conditioner is different and the dew condensation is likely to occur due to the difference in the up-down wind sweeping angle and the left-right wind sweeping angle. The use of temperature-first-chance control logic may cause the operating environment that does not require condensation to also enter the anti-condensation program, thereby causing poor air conditioning cooling and user experience.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings and examples. It should be understood that the following specific examples are only for illustrating the present invention and are not to be construed as limiting the present invention.
The existing machine type condensation prevention control generally controls whether to enter a condensation prevention program or not through the difference value between the temperature of an inner machine pipe of an air conditioner and the ambient temperature. First, a threshold value is set, and when the difference value reaches the threshold value, the system enters an anti-condensation program.
As shown in fig. 1 and 2, the rotation angles of the left and right wind-sweeping guide plates and the up and down wind-sweeping blades are generally set within a set range, for example, the left and right wind-sweeping guide plates are rotated within a range from a position a1 to a5, and the up and down wind-sweeping blades are rotated within a range from a position C1 to a position C4.
Because the upper and lower wind sweeping angles and the left and right wind sweeping angles are different, the air output of the air conditioner is also different, and the condition of easy condensation is also different. If the original temperature control logic in a general way is used, the operation environment without condensation can enter the condensation preventing program, so that the refrigeration effect of the air conditioner is poor, and the user experience is also poor.
The machine type that can design with the fixed grid to the wind baffle is swept about to the left and right sides, sweeps the wind about the wind guide plate and about, i.e. has the model of the wind of sweeping about with a plurality of positions, and the easy condensation's situation can be improved. The anti-condensation control method of the air conditioner provided by the invention is suitable for an anti-condensation machine type with the air sweeping controllable in a freeze-stop manner at the upper part, the lower part, the left part and the right part as an addition part.
The anti-condensation control method provided by the invention refines the existing air conditioner anti-condensation control method, and further judges whether the air conditioner needs to enter an anti-condensation program according to whether the sweep air is in a stop motion state when the difference value between the temperature of an inner machine pipe and the temperature of the indoor environment reaches a set threshold value, so as to avoid the occurrence of poor refrigeration effect caused by entering the anti-condensation program when the sweep air is in the stop motion state.
The anti-condensation control method provided by the invention comprises the following steps:
when the difference value between the temperature of the inner pipe of the air conditioner and the indoor environment temperature reaches a set threshold value, judging whether the left-right air sweeping and the up-down air sweeping are in a stop-motion control state, and when the left-right air sweeping or the up-down air sweeping are not in the stop-motion control state, entering an anti-condensation program by the air conditioning system; when the left and right air sweeping and the up and down air sweeping are simultaneously in the freeze frame control state, the air conditioning system does not enter the condensation preventing program.
The judgment condition of the freeze control state includes a first judgment condition and a second judgment condition, wherein:
the first judgment condition is that the rotation angle range of the left and right wind sweeping guide plates is in the stop motion setting range, and the left and right wind sweeping stop motion control is judged;
the second judgment condition is the rotating angle range of the up-down wind sweeping, and when the rotating angle range of the up-down wind sweeping blades is in the freeze frame setting range, the up-down wind sweeping freeze frame control is judged.
Due to the fact that two entering conditions are added, whether the anti-condensation program needs to enter or not can be determined by judging the angle states of the left-right wind sweeping and the up-down wind sweeping. The range of the stop-motion angle of the left and right wind sweeping guide plates and the upper and lower wind sweeping blades can be optimized according to the actual measurement condition.
As shown in fig. 1, when the left-right wind-sweeping stop angles are at the position a1 and the position a5, the wind-out state is not good, and condensation is likely to occur. At this time, if the left and right air-sweeping guide plates are fixed to operate in the range of the position a2 and the position a4, the occurrence of condensation is greatly reduced. Similarly, in the upper and lower wind sweeping blades shown in fig. 2, if the wind guiding blade stays in the range from the position C1 to the position C2, the wind outlet state is not good, and condensation is easily caused, and if the upper and lower wind sweeping blades are made to avoid the range, the condensation is greatly reduced when the upper and lower wind sweeping blades are fixed to operate in the range from the position C2 to the position C4.
If the air conditioner is operated in a freezing state, namely the left and right wind sweeping angle ranges are between the position A2 and the position A4, and the up and down wind sweeping angle ranges are between the positions C2 and C4, even if the temperature difference between the inner pipe of the air conditioner and the indoor environment reaches a set threshold value, the air conditioner does not need to enter into an anti-condensation state.
As shown in fig. 3, in an embodiment, the anti-condensation control method provided by the present invention includes:
step 1, judging whether the difference value between the temperature of a machine pipe in the air conditioner and the ambient temperature reaches a set threshold value;
step 2, when the difference value between the temperature of the machine pipe in the air conditioner and the ambient temperature reaches a set threshold value, determining whether the air conditioner is in stop-motion control operation or not by using a first judgment condition and a second judgment condition; the stop motion control comprises left-right wind sweeping stop motion control and up-down wind sweeping stop motion control;
step 3, if the air conditioner simultaneously meets the first judgment condition and the second judgment condition, the air conditioner does not enter into an anti-condensation program; and if the air conditioner does not meet the first judgment condition or the second judgment condition, entering into the anti-condensation program for operation.
That is, the upper and lower wind sweeping angle limits and the left and right wind sweeping angle limits are added, and when any one limit condition is not met, the system can automatically control to enter an anti-condensation program; and when the two limiting conditions are simultaneously met, the anti-condensation program is not started to run.
Taking the NF 50 model (geli leading wall hanging machine) as an example, the left and right air sweeping guide plates are shown in fig. 1 and the following table, when the left and right air sweeping guide plates are driven to the leftmost position a1 or the rightmost position a5, the air volume is small, the air outlet temperature is lowest, the air outlet temperature is severe, the condensation phenomenon is easy to occur, and the position a2 and the position a4 are the second and the middle position 3 is the better. When the left and right air sweeping guide plates are positioned in the fixed grid range of the position A2-A4 to operate, the condensation prevention control function is completely not needed due to smooth air outlet, large air volume and high air outlet temperature. And in consideration of the comfort of the refrigeration effect, a left and right wind sweeping stop motion can be added for condensation prevention control.
Aiming at the new increasing and preventing condensation entering conditions of left and right wind sweeping:
stop position A2 < left-right wind-sweep angle < stop position A4.
In this embodiment, the left and right air-sweeping guide plates are operated at the position a1 to the position a5, i.e., in the range of 5 ° to 120 ° positions, without determining the state of the grid. When the difference between the temperature of the inner pipe and the ambient temperature reaches a set threshold, the air conditioner can enter an anti-condensation program. When the left and right air sweeping guide plates operate at the stop motion position, the position A2-A4 ranges from 33 degrees to 92 degrees, and even if the difference value between the temperature of the inner pipe and the ambient temperature reaches a set threshold value, the air conditioner can not enter an anti-condensation program.
Similarly, aiming at the upper and lower wind sweeping, newly-added condensation-preventing entering conditions are as follows: the rotating angle range of the upper and lower air guide blades is C2-C4.
As shown in fig. 2 and the following table, the upper and lower guide vanes rotate within the range of positions C1-C4, which in this embodiment is 170 ° -90 ° (relative to the linear coordinate tangent to the sweep vanes). Obviously, when the upper and lower air guide blades rotate to the position C1-C2 (170-120 degrees), the air outlet is not smooth, the air outlet volume is small, the air outlet temperature is low, and the condensation phenomenon is easy to form. At the moment, when the difference value between the temperature of the inner pipe and the ambient temperature reaches a set threshold value, the system automatically enters an anti-condensation program. If the air conditioner runs under the stop-motion control, namely the upper and lower air sweeping blades run in the range of C2-C4, namely the range of 120-90 degrees, the air outlet condition is good, and the condensation phenomenon is not easy to occur. Even if the difference between the temperature of the inner pipe and the ambient temperature reaches a set threshold, the air conditioning system cannot enter an anti-condensation program.
In order to realize the anti-condensation control method, the invention also provides an anti-condensation control device of the air conditioner, which comprises the following steps:
the first judgment module is used for determining whether the temperature difference between the inner pipe of the air conditioner and the indoor environment reaches a set threshold value;
the second judgment module is used for determining whether the left-right wind sweeping and the up-down wind sweeping of the air conditioner are in a freeze frame control state;
and the control module is used for carrying out anti-condensation control on the air conditioner.
The judgment condition of the freeze control state comprises a first judgment condition and a second judgment condition, wherein:
the first judgment condition is that the rotating angle range of the left air sweeping guide plate and the right air sweeping guide plate is not in the freezing set range, and the controller controls the air conditioner to enter an anti-condensation program;
and the second judgment condition is that the rotating angle range of the upper and lower wind sweeping blades is not within the freeze-frame set range, and the controller controls the air conditioner to enter an anti-condensation program.
The invention also provides an air conditioner using the anti-condensation control method.
The idea provided by the invention is to refine the original anti-condensation program again, so that the air conditioner is prevented from entering the anti-condensation program only according to temperature control, the air conditioner can enter the anti-condensation program only under the condition of poor air outlet, and the refrigeration effect and the user experience are improved.
The foregoing is considered as illustrative only of the embodiments of the invention. It should be understood that any modifications, equivalents and changes made within the spirit and framework of the inventive concept are intended to be included within the scope of the present invention.
