wherein: the first temperature sensor and the second temperature sensor are respectively arranged on different wall surfaces of the inner wall of the space; the first humidity sensor and the first temperature sensor are arranged at the same position, and the second humidity sensor and the second temperature sensor are arranged at the same position; the valve group at least comprises two valves, and each valve in the valve group is respectively arranged on different wall surfaces of the inner wall of the space.
In this embodiment, the starting of the temperature control means starting the temperature control device, and the temperature control includes temperature reduction and temperature rise, which are not substantially different in the solution provided by the present invention, and only the adjustment directions of the corresponding valve groups may be opposite. It should be noted that the temperature control device or the temperature control apparatus in the embodiment of the present invention mainly refers to a refrigeration apparatus, including but not limited to an air conditioner, and unless otherwise specified, the present invention is described with an example of cooling. Similarly, the starting of the humidity control means starting the humidity control device, and the humidity control includes reducing the humidity and increasing the humidity, which are not substantially different in the solution provided by the present invention, and only the adjustment directions of the corresponding valve sets may be opposite. It should be noted that the humidity control device or the humidity control apparatus in the embodiments of the present invention mainly refers to a humidifier, including but not limited to a stand-alone humidifier and a humidifier combined with other apparatuses such as an air conditioner, and the present invention is described by taking a humidification process as an example unless otherwise specified.
In the present embodiment, the present invention is described by taking two temperature sensors and two humidity sensors as an example, and in fact, the number of the temperature sensors and the humidity sensors may be increased, and correspondingly, the number of the valve groups is divided according to the number of the temperature sensors or the humidity sensors. In this embodiment, two temperature sensors or two humidity sensors are preferably disposed on opposite sides of a space, such as on opposite walls, and are preferably mounted at the same height or slightly lower than that of a typical adult. It can be understood that, since the present invention is controlled based on the detection values of the temperature sensor and the humidity sensor, the higher the coincidence degree between the actually used area in the space and the two humidity sensors or the area between the two humidity sensors, the better the control effect. However, no matter where the temperature sensor and the humidity sensor are specifically disposed in the space, there is no essential influence on the implementation logic of the scheme of the present invention, and the difference is only that slight differences in effect may exist.
In the embodiment, after the temperature control is started, the opening degree of the valve group is adjusted to enable the cold air to purposefully flow to a specific direction or position, so that the temperature in the space is reduced more quickly and uniformly, and finally the effect that the first temperature sensor and the second temperature sensor detect the same or similar is achieved. Of course, the same is considered in terms of errors and the same within an acceptable degree, and numerical values in a mathematical sense are not completely equal, for example, the difference between the numerical values of 1-2 degrees celsius may be considered to be the same within the acceptable degree by taking the somatic sensation of a human body as a reference, which belongs to the content that a user can customize, and this is not specifically limited in the embodiment of the present invention.
In the present embodiment, the humidity sensors correspond to the arrangement positions of the temperature sensors, and it is preferable that the first temperature sensor and the first humidity sensor are arranged at the same position, and the second temperature sensor and the second humidity sensor are arranged at the same position.
In this embodiment, the opening degree of the valve group is adjusted according to the detection values of the first and second humidity sensors. In this embodiment, the number of the valves is greater than or equal to the number of the walls of the space, preferably at least one valve is provided on each wall, and the air can flow to the wall where the valve is located by opening or closing the valve.
In this embodiment, the present invention provides a solution that can easily determine the positions of each sensor, valve, temperature control device and humidity control device by establishing a three-dimensional space area for a medium-small space range, so as to calculate the required parameters.
In this embodiment, the first length, the first corner, the second length, and the second corner may be calculated by a coordinate relationship, for example, the first length is a length of a connection line between two points, and when two points are not aligned (a block exists between two points), the first length is a sum of lengths of a plurality of line segments. In this embodiment, when two points (for example, a sensor and a refrigeration device) are opposite, the rotation angle of the two points is 0 degree, otherwise, the rotation angle is the sum of included angles of a plurality of line segments connecting the two points.
The method provided by the invention enables the air in the space to flow directionally by controlling the opening degree of the valve, so that cold air and water vapor can flow to the area with higher temperature or lower humidity more quickly, and the speed of uniformly distributing the temperature and the humidity in the space is accelerated under the condition of not changing the working states of the temperature control device and the humidity control device.
In one embodiment of the invention, the weighted temperature is calculated by:
wherein:
、
weighted temperatures of the first temperature sensor and the second temperature sensor, respectively;
、
the detection values of the first temperature sensor and the second temperature sensor are respectively detected;
、
a first length and a second length, respectively;
、
respectively a first corner and a second corner;
a 0 degree corner coefficient for preventing a corner from being 0 degrees, which is a selected fixed value;
is the shortest path length between the first temperature sensor and the second temperature sensor.
In the present embodiment, the weighted temperature of the detected point can be determined by the above two equations. As can be seen from the above two equations, the weighted temperature is related to the actual arrangement of the temperature sensors in the space, and for a specific arrangement form in a certain space, the weighted temperature is only related to the detected value of the temperature. By setting the weighted temperature, the influence of the arrangement conditions in the environment on the temperatures of the different detection points is taken into account. It should be noted that, the influence here does not mean that the accuracy or the authenticity of the collected temperature is influenced, but the adjustment process of the valve group is influenced, and for the same detected temperature, under different arrangement conditions, different valve group openings are obtained, so that the adjustment of the valve group openings is adapted to the specific arrangement form.
In an embodiment of the present invention, the controlling the opening of the valve set according to the weighted temperature difference includes:
respectively calculating the shortest path length of each valve from the first temperature sensor and the second temperature sensor;
for any valve, taking the shortest path length of the temperature sensor with the smallest distance from the valve as a regulating coefficient to obtain a first valve group corresponding to the first temperature sensor and a second valve group corresponding to the second temperature sensor;
and calculating the deviation rate of the weighted temperature and the weighted value of the set temperature for the first valve group or the second valve group, calculating the total opening of the corresponding valve group according to the obtained deviation rate, and distributing the total opening to each valve by the regulating and controlling coefficient.
In this embodiment, it can be understood that any one of the valves is classified into the valve group corresponding to the temperature sensor having the smallest distance. Therefore, the valves need to be arranged in a distributed manner during valve arrangement.
In this embodiment, the weighted temperature value is set to
Wherein
Is a set temperature value. Taking the first temperature sensor as an example, the deviation ratio is
. The total opening of the valve group is equal to the product of the deviation ratio and a default total opening, which is equal to the sum of the number of gears per valve. And distributing the total opening degree to each valve by the regulating and controlling coefficients, for example, a valve group comprises 3 valves, the regulating and controlling coefficients are a1, a2 and a3 respectively, the opening degree distributed to the first valve is the product of a 1/(a 1+ a2+ a 3) and the total opening degree distributed to the valve group, and the result is rounded and is not more than the maximum gear of the corresponding valve.
In an embodiment of the present invention, the adjusting the current opening of the valve group according to the detection values of the first and second humidity sensors includes:
calculating the temperature difference between the first temperature sensor and the second temperature sensor at the front and the back acquisition moments;
calculating the humidity difference between the first humidity sensor and the second humidity sensor at the two previous and next acquisition moments;
judging whether the temperature difference and the humidity difference change in the same direction;
if the temperature difference and the humidity difference change in the same direction, the first valve group and the second valve group are adjusted in the same direction;
if the change of the temperature difference and the humidity difference is different, the first valve group and the second valve group are reversely adjusted.
In the present embodiment, the same direction of change here means that both the temperature difference and the humidity difference increase or both decrease. In this embodiment, the adjustment amplitude is equal to the percentage of the two changes before and after the temperature difference or the humidity difference, and the obtained percentage is multiplied by the total opening degree of the valve group and then distributed to each valve.
In one embodiment of the present invention, the equidirectionally adjusting first and second valve groups comprises:
judging whether the difference between the temperature difference and the humidity difference is equidirectionally expanded or not;
if so, reducing the opening difference between the first valve group and the second valve group;
if not, synchronously increasing the opening degrees of the first valve group and the second valve group;
the reverse trim first and second valve groups comprising:
judging whether the difference between the temperature difference and the humidity difference is anisotropic expansion;
if yes, the total opening degree of the first valve group and the second valve group is adjusted;
if not, the total opening degree of the first valve group and the second valve group is synchronously reduced.
In this embodiment, it can be understood that, when the valve is expanded in the same direction, the opening difference between the first valve group and the second valve group is reduced, and if the valve is reduced in the same direction, the openings of the first valve group and the second valve group are synchronously increased; if the difference direction is enlarged, the total opening degree of the first valve group and the second valve group is exchanged, and if the difference direction is reduced, the total opening degree of the first valve group and the second valve group is synchronously reduced.
In one embodiment of the present invention, the dynamically adjusting the opening degree of the valve group according to the temperature difference and the humidity difference to equalize the temperature and the humidity in the space includes:
monitoring the detection values of the first temperature sensor and the second temperature sensor;
if the detection value of the first temperature sensor or the detection value of the second temperature sensor exceeds a preset temperature interval, judging whether the detection value exceeding the preset temperature interval is higher or lower;
if the detection value exceeding the preset temperature interval is higher, the opening degree of the corresponding valve group is reduced; if the detection value exceeding the preset temperature interval is lower, the opening degree of the corresponding valve group is increased;
monitoring the detection values of the first humidity sensor and the second humidity sensor;
if the detection value of the first humidity sensor or the detection value of the second humidity sensor exceeds a preset humidity interval, judging whether the detection value exceeding the preset humidity interval is higher or lower;
if the detection value exceeding the preset humidity interval is higher, the opening degree of the corresponding valve group is increased; if the detected value exceeding the preset humidity interval is lower, the opening of the corresponding valve group is reduced.
In the embodiment, the above steps provide a method for adjusting a single amount of temperature and humidity exceeding a set interval, and the temperature or humidity can be quickly adjusted to be within the set interval by this adjustment method. The adjustment amplitude can be adjusted according to the magnitude of the exceeding deviation ratio with reference to the foregoing embodiment, and of course, a fixed value can also be set as the adjustment amplitude, and the adjustment is performed once every adjustment period. The adjustment period here is several times, for example 50 or 100 times, the sampling period of the temperature or humidity.
In an embodiment of the present invention, the multi-valve based temperature and humidity control method further includes:
