The specific temperature and humidity control method corresponding to the constant temperature and humidity wine cabinet in this embodiment is shown in fig. 3 as follows: the control method comprises a control method corresponding to N times of start and stop before the compressor 700 and a control method after N times of start and stop, and in order to facilitate control, initial parameters of the wine cabinet are set firstly in the embodiment: the temperature difference between the start and stop of the compressor 700 is set to be DeltaT, because to realize the constant temperature in the wine storage cavity 210, the start-up temperature and the stop temperature of the compressor 700 need to be limited, and the smaller the temperature difference between the start and stop is, the better the constant temperature effect is.
The upper limit value corresponding to the preset humidity interval is as follows: RH-H, H is a first humidity deviation value, and the lower limit value of the preset humidity interval is: RH-L, L is the second humidity deviation value, the duty ratio RF-N of the air supply device 600 when the compressor 700 is started, the duty ratio RF-F of the air supply device 600 when the compressor 700 is stopped, and the set temperature is: ts, the actual temperature in the wine storage chamber 210 is: t1, the actual humidity in the wine storage cavity 210 is: RH.
Specifically, the preset temperature in the wine storage chamber 210 in this embodiment includes: a first preset temperature and a second preset temperature, wherein the first preset temperature is greater than the second preset temperature, namely the first preset temperature is the upper limit temperature set in the wine storage cavity 210, and the second preset temperature is the lower limit temperature set in the wine storage cavity 210; the first preset temperature is equal to the sum of the set temperature in the wine storage cavity 210 and the start-up temperature difference of the compressor 700; the second preset temperature is equal to the difference between the set temperature in the wine storage chamber 210 and the start-up temperature of the compressor 700.
The temperature and humidity control method after the compressor 700 is started and stopped for N times comprises the steps of detecting the temperature in the wine storage cavity 210, and controlling the start and stop of the compressor 700 and the air supply device 600 according to the relation between the temperature in the wine storage cavity 210 and the preset temperature in the wine storage cavity 210.
In the initial start-up state, the temperature in the wine storage cavity 210 cannot meet the requirement, so the temperature and humidity control method in the embodiment firstly controls the compressor 700 to act so that the temperature in the wine storage cavity 210 reaches the set temperature, and in the specific control, the temperature in the wine storage cavity 210 is detected by the temperature detection element, the synchronous start-up and stop of the compressor 700 and the air supply device 600 are controlled according to the temperature, and if the detected temperature of the wine storage cavity 210 reaches the first preset temperature, the compressor 700 and the air supply device 600 are controlled to be started simultaneously; if the detected temperature of the wine storage chamber 210 reaches the second preset temperature, the compressor 700 and the air supply device 600 are controlled to stop at the same time.
In the previous N times of control process of the compressor 700, the air supply device 600 and the compressor 700 are synchronously started and stopped, so that the temperature in the wine storage cavity 210 is quickly pulled to a preset temperature, and the temperature in the wine storage cavity 210 reaches the temperature requirement stored in the wine cabinet.
Step 2, the control method after the compressor 700 is started and stopped for N times comprises the following steps:
after the compressor 700 and the air supply device 600 are started for the (n+1) th time, detecting the temperature in the wine storage cavity 210 and the humidity in the wine storage cavity 210, and if the temperature in the wine storage cavity 210 reaches the preset temperature and the humidity in the wine storage cavity 210 does not exceed the preset humidity interval, adjusting the duty ratio of the air supply device 600 to enable the air supply device 600 to continue to run with the adjusted duty ratio;
if the temperature in the wine storage cavity 210 reaches the preset temperature and the humidity in the wine storage cavity 210 exceeds the preset humidity interval, the start and stop of the compressor 700 are controlled according to the magnitude relation between the temperature in the wine storage cavity 210 and the preset temperature.
Specifically, after the compressor 700 and the air supply device 600 are started and run for a period of time, the temperature in the wine storage cavity 210 is detected, and after the compressor 700 is started and stopped for N times, if the temperature of the wine storage cavity 210 is detected to reach the first preset temperature and the humidity in the box reaches the upper limit value corresponding to the preset humidity interval, the duty ratio of the air supply device 600 when the compressor 700 is stopped is increased.
If it is detected that the temperature in the box reaches the second preset temperature and the humidity value in the box reaches the lower limit value corresponding to the preset humidity interval, the duty ratio of the air supply device 600 when the compressor 700 is started is reduced.
Preferably, the upper limit value corresponding to the preset humidity interval is the difference between the preset humidity in the wine storage cavity 210 and the first humidity deviation value, and the lower limit value corresponding to the preset humidity interval is the difference between the preset humidity and the second humidity deviation value.
The specific control implementation process of the constant temperature and humidity wine cabinet in the embodiment is as follows:
the whole wine cabinet is controlled to be electrified and started, meanwhile, the compressor 700 and the air supply device 600 are controlled to start to operate, when the wine storage cavity 210 is operated for the first N times, the temperature in the wine storage cavity 210 is transmitted to the controller to control the start and stop of the evaporator 400 and the air supply device 600, in the embodiment, N is taken for 10 times, and when the wine storage cavity 210 is operated for the first 10 times, only the temperature value in the wine storage cavity 210 is detected to reach the first preset temperature, the compressor 700 and the air supply device 600 are controlled to be started;
as soon as the temperature value in the wine storage chamber 210 reaches the second preset temperature, the compressor 700 and the air supply device 600 are controlled to stop. After the operation is performed 10 times, the temperature in the wine storage cavity 210 basically reaches to be stable, when the temperature in the wine storage cavity 210 reaches the first preset temperature for the (n+1) th time, the compressor 700 and the air supply device 600 are controlled to be started, then the operation is performed for a period of time, the temperature in the wine storage cavity 210 is detected, if the temperature does not reach the second preset temperature, the compressor 700 and the air supply device 600 keep operating under the original working condition, if the temperature reaches the second preset temperature, the humidity in the wine storage cavity 210 is continuously judged, and if the humidity in the wine storage cavity 210 does not reach the lower limit value of the preset humidity interval, the duty ratio of the air supply device 600 when the compressor 700 is started is correspondingly reduced, so that the air supply device 600 operates at the adjusted duty ratio.
Because the wine cabinet in this embodiment is an air-cooled wine cabinet, the cooling capacity of the evaporator 400 is mainly induced by the air supply device 600, so as to achieve cooling, when the temperature in the wine storage cavity 210 is detected to reach the second preset temperature required to be stopped, in order to keep the temperature in the wine storage cavity 210 relatively constant, the corresponding speed of reducing the temperature in the box is required, and the cooling capacity of the air supply device 600 is reduced, so that the temperature in the wine storage cavity 210 is kept in a relatively constant range as much as possible. In this embodiment, the duty ratio of the air supply device 600 is correspondingly reduced, and the rotation speed of the air supply device 600 is reduced by reducing the duty ratio, so that the cooling capacity of the air supply device 600 blown into the wine storage cavity 210 is reduced, and meanwhile, the rotation speed of the air supply device 600 is reduced, so that the water vapor amount blown into the wine storage cavity 210 through the air supply device 600 is reduced, and further, the humidity in the box can be ensured to quickly reach the lower limit value of the preset humidity interval, and the compressor 700 can be quickly stopped to maintain the constant temperature in the box.
If it is detected that the temperature in the wine storage cavity 210 reaches the second preset temperature and the humidity is less than the lower limit value of the preset humidity interval, the corresponding control compressor 700 is stopped, and the air supply device 600 keeps in a continuous operation state, so that water vapor is conveyed into the wine storage cavity 210 through the air supply device 600, and the humidity in the wine storage cavity 210 is ensured to be constant.
If it is detected that the temperature in the wine storage chamber 210 does not reach the preset temperature and the humidity is within the preset humidity range, the compressor 700 and the air supply device 600 are controlled to operate under the original working conditions.
After the compressor 700 is shut down, since the compressor 700 does not control the evaporator 400 to cool down, the temperature in the wine storage cavity 210 will rise, at this time, the temperature in the wine storage cavity 210 is continuously detected, if the temperature in the wine storage cavity 210 reaches the first preset temperature, the humidity in the wine storage cavity 210 is continuously detected, if the humidity in the wine storage cavity 210 does not reach the upper limit value of the preset humidity interval, the duty cycle of the air supply device 600 is increased, specifically, since the temperature rise in the wine storage cavity 210 has reached the first preset temperature, the start-up is needed at this time, but since the humidity at this time does not reach the upper limit of the preset humidity interval, the start-up will cause the humidity to drop greatly, and constant humidity cannot be guaranteed, at this time, when the temperature in the wine storage cavity 210 reaches the upper limit value of the preset humidity interval, the temperature and humidity in the wine storage cavity 210 are set to be relatively constant, at this time, the corresponding rotational speed of the air supply device 600 is increased, so that the residual cold amount on the evaporator 400 can be blown out to the wine storage cavity 210 in a large amount, and the effect of reducing the temperature in the wine storage cavity 210 is achieved, and at the same time, the air compressor 700 can be quickly started up after the temperature of the temperature in the preset humidity interval is increased, the temperature of the air storage cavity 210 is quickly reached, and the temperature in the humidity of the air storage cavity is quickly, and the air compressor is quickly turned on, and the temperature in the temperature can be quickly turned on, and the temperature can be quickly cooled down, and the temperature can be quickly up, and the temperature can be cooled.
The above embodiments are only for illustrating the technical solution of the present application, and are not limiting; although the application has been described in detail with reference to the foregoing embodiments, it will be apparent to one skilled in the art that modifications may be made to the technical solutions described in the foregoing embodiments, or equivalents may be substituted for some of the technical features thereof; such modifications and substitutions do not depart from the spirit and scope of the corresponding technical solutions.
