The adjusted frequency mainly acts on the compressor, the size of the running frequency of the compressor determines the size of the cooling capacity of the whole air conditioner, the frequency is increased, the cooling capacity output of the air conditioner is increased, the intermediate temperature (also called as the temperature of an inner pipe) of the evaporator is lowered, the frequency is reduced, the cooling capacity of the air conditioner is reduced, the temperature of the inner pipe is increased, and therefore the temperature of the inner pipe of the air conditioner can be changed by adjusting the frequency.

Example 2
As shown in fig. 2, in the present embodiment, an air conditioner is provided, which is configured with one or more processors, a memory, and one or more application programs, wherein the one or more application programs are stored in the memory and configured to be executed by the one or more processors, and the one or more programs are configured to execute the dehumidification control method according to any one of embodiments 1.
In this embodiment, an indoor unit of an air conditioner includes: the air conditioner comprises a shell, a fan and a controller, wherein the shell is provided with an installation cavity, and an air inlet and an air outlet which are communicated with the installation cavity are formed in the shell; the evaporator is arranged in the mounting cavity; the air inlet closed air deflector 3 is arranged at the air inlet and used for adjusting the air inlet quantity of the air conditioner; the air outlet air deflector 2 is arranged at the air outlet and is provided with a direct blowing prevention working position which can prevent the air outlet from directly blowing the user on the rotating path; and the temperature and humidity detection device 1 is used for detecting the indoor environment temperature and humidity.
Furthermore, in this embodiment, an adjustable air outlet air deflector and an adjustable air inlet closed air deflector are provided after the air conditioner is improved, wherein the air outlet air deflector is driven by two gear boxes to perform telescopic motion, so as to realize the pushing and closing motion of the air outlet air deflector, and a small motor is assembled at the top end of a gear rod of the right driving box and used for driving the air outlet air deflector to perform rotary motion; the air inlet closed air deflector component consists of 6 small air deflectors, the linkage rod is driven by the motor to drive the air inlet air deflector switch to be closed, and the physical angle of the movement range is 0-90 degrees.
Firstly, the air conditioner is provided with three components, namely an air outlet air deflector, an air inlet closed air deflector and a humidity sensor, wherein one of the three components is not available. The humidity sensor is used for detecting the environment humidity; the air outlet air deflector is used for adjusting the position of the air outlet air deflector when the air outlet temperature is very low due to too low temperature of the pipe during rapid dehumidification, so that cold air is prevented from directly blowing people. The closed air guide plate component for air inlet has the function of changing the air inlet amount, and can reduce the temperature value of the pipe and accelerate dehumidification on the premise of not changing the rotating speed of an inner fan of the air conditioner.
After the air conditioner is electrified, the humidity sensor starts to detect the ambient humidity, and aiming at the first electrification, in order to avoid the detection value to be influenced by the local humidity around the humidity sensor, the initial effective detection value of the humidity sensor is set as follows: after the air conditioner is electrified for the first time, the air conditioner is continuously detected for 3min from the starting moment of an inner fan of the air conditioner, during the period, the change value of the humidity value is detected to be less than 2% within 1min continuously, the initial detection value is considered to be effective, the detection value (the first effective humidity value) at the 3min moment is fed back to a main board of the air conditioner, a main chip on the main board calculates and judges, the preset humidity interval to which the main chip belongs is judged according to the first effective humidity value obtained by detection, and then the initial dehumidification sub-mode is determined and the corresponding dehumidification sub-modes in the dehumidification mode are sequentially executed. If the air conditioner is always in the running state and is influenced by environmental factors (rain), the room humidity is suddenly increased, the humidity sensor continuously detects within 20min, and meanwhile the indoor relative humidity is met
The indoor environment temperature is less than 28 deg.C, the air conditioner matches the preset humidity interval according to the humidity value measured at 20min, and then determinesThe method includes initializing a dehumidification sub-mode and sequentially executing corresponding dehumidification sub-modes in the dehumidification mode.
The physical adjusting angle of the air inlet closed air deflector is 0-90 degrees, the closing state is set to be a zero point (0 degrees), and the corresponding humidity adjusting interval is divided into 4-gear positions:
| |
1 gear (0-22.5 degree) |
| Constant |
2 gear (22.5-45 degree) |
| |
3 grade (45-67.5 degree) |
| Exit interval | 4 gear (67.5-90 degree) |
When humidity sensor detects that humidity is greater than 80%, the main procedure sends out quick dehumidification regulation signal, and the closed aviation baffle of air inlet is rotatory to 1 gear position, moves the air-out aviation baffle and gets into and prevent the direct-blow angle, and the indoor unit simply calculates dew point temperature Td through the formula simultaneously, and the accuracy is 0.5 ℃, as follows:
where Td is the dew point temperature and Tinner loop is the indoor ambient temperature. The calculation of the dew point temperature Td has a certain error, and the control strategy tolerance is 1 ℃. And the difference value is calculated between the dew point temperature calculated by the inner unit and the intermediate temperature feedback value of the evaporator and is sent to the outer unit, and the outer unit performs frequency modulation action through the existing difference value.
Here, we set an adjustment target range of a difference Δ T between a calculated dew point temperature and an inner tube temperature of four frequency modulation intervals for an external machine in combination with a dehumidification mode and other operation modes after dehumidification quitting, see table two:
watch two
| Fast dehumidifying zone | △T＞12℃ |
| Constant speed dehumidification interval | 6℃≤△T＜12℃ |
| Slow dehumidifying zone | 0℃≤△T＜6℃ |
| Exit interval | △T＜0℃ |
And after the external machine receives the initial difference signal of the internal machine, the main program refers to the target value of the second table for judgment, frequency increasing is executed or the current frequency value is maintained, and when the delta T meets the binary value of the second table, the whole machine maintains the current state. When the humidity sensor detects that the humidity value is smaller than the humidity range of the current interval within 3min continuously, the next adjusting interval is automatically entered, the gear change of the closed air deflector is shown as table I, the air outlet deflectors of the fast dehumidification interval, the normal speed dehumidification interval and the slow dehumidification interval are all at the direct blowing prevention position, the air deflector of the exit interval returns to the user setting position, and other adjusting actions are the same as the adjusting mode of the interval A.
Conventional refrigeration dehumidification simply reduces the tube temperature by high frequency operation and the frequency is limited to the set temperature. The invention is not limited by the method, and can accelerate the temperature reduction of the inner tube of the evaporator by the air quantity reducing method, the effect is more obvious than single frequency control, the power consumption is not increased, the system can detect by itself, and the artificial regulation and control are not needed.
Exemplary embodiments of the present disclosure are specifically illustrated and described above. It is to be understood that the present disclosure is not limited to the precise arrangements, instrumentalities, or instrumentalities described herein; on the contrary, the disclosure is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
