Detailed Description
in order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the following description will be made with reference to the accompanying drawings. It is obvious that the drawings in the following description are only some examples of the invention, and that for a person skilled in the art, other drawings and embodiments can be derived from them without inventive effort.
it will be understood that the terms "comprises" and/or "comprising," when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.
For the sake of simplicity, the drawings only schematically show the parts relevant to the present invention, and they do not represent the actual structure as a product. In addition, in order to make the drawings concise and understandable, components having the same structure or function in some of the drawings are only schematically illustrated or only labeled. In this document, "one" means not only "only one" but also a case of "more than one".
according to a first embodiment of the present invention, as shown in fig. 1, a sterilization control method for an air handling unit includes:
S100, after the air handling unit is powered on, judging whether a sterilization condition is met, if so, starting a sterilization function;
S200, acquiring an intra-cavity temperature value and an intra-cavity relative humidity value of the air handling unit;
s300, calculating sterilization duration according to the temperature value in the cavity and the relative humidity value in the cavity;
s400, when the starting time of the sterilization function reaches the sterilization time, closing the sterilization function.
Specifically, the invention arranges a sterilizing lamp with sterilizing function in the air processing unit, such as an ultraviolet sterilizing lamp or a pulse strong light sterilizing lamp, and the sterilizing function is realized by controlling the on-off of the sterilizing lamp so as to sterilize the parts in the air processing unit. The internal structure of the air handling unit is schematically shown in fig. 2.
After the air treatment unit is powered on, when the sterilization condition is judged to be reached, the sterilization function is started. For example, when the time from the last power-off time when the air handling unit is powered on is longer than a preset number of days (e.g., 1 day), it is determined that the sterilization condition is reached, and when the air handling unit is powered on, the sterilization function of the air handling unit is directly started.
when the sterilization function is started, the intracavity temperature value and the intracavity relative humidity value of the air handling unit are obtained, and then the required sterilization duration is calculated according to the intracavity temperature value and the intracavity relative humidity value. And when the starting time of the ultraviolet germicidal lamp reaches the calculated germicidal time, closing the germicidal function.
Different temperature and humidity values can influence the sterilization effect of the ultraviolet germicidal lamp, so that the sterilization duration obtained by calculation according to the temperature value in the cavity and the relative humidity value in the cavity is more in line with the actual requirement. Compared with the existing sterilization mode that the ultraviolet germicidal lamp and the unit operate simultaneously, the invention not only can effectively kill bacteria in the air treatment unit, but also can prevent the ultraviolet germicidal lamp from operating for a long time and reducing the working life of the ultraviolet germicidal lamp, and simultaneously prevent other parts in the cavity from being accelerated to age and shorten the service life because of being irradiated by the ultraviolet germicidal lamp for a long time.
According to a second embodiment of the present invention, as shown in fig. 3, a sterilization control method for an air handling unit includes:
S110, when the air handling unit is powered on, acquiring the working state recorded when the air handling unit is powered off last time;
s120, judging whether to start a sterilization function or not according to the working state;
if S130, starting a sterilization function;
s140, if not, determining the interval duration from the next start of the sterilization function according to the working state;
S150, when the power-on duration reaches the interval duration, starting a sterilization function;
s200, acquiring an intra-cavity temperature value and an intra-cavity relative humidity value of the air handling unit;
s300, calculating sterilization duration according to the temperature value in the cavity and the relative humidity value in the cavity;
S400, when the starting time of the sterilization function reaches the sterilization time, closing the sterilization function.
Specifically, the air treatment unit is further provided with a power-off memory function, the working state of the air treatment unit at the power-off moment is recorded when the air treatment unit is powered off, for example, when the air treatment unit is being sterilized during power-off, the current sterilization state is recorded, when the air treatment unit is powered on again, the sterilization function is directly started according to the working state, the sterilization duration is calculated according to the temperature value and the relative humidity value in the cavity, and the sterilization function is completed.
When the power is off, the sterilization function is not started, the time length from the next time of starting the sterilization function is recorded, and the time of the power-off moment is recorded. When the air handling unit is powered on again, the real time length from the next start of the sterilization function after power-on is determined according to the recorded time length from the next start of the sterilization function in the working state, the last power-off time and the power-on time again, and when the power-on time length reaches the real time length, the sterilization function is started. And when the time condition of starting the sterilization function is met during power-on according to the recorded time length of starting the sterilization function next time in the working state, the last power-off time and the power-on time again, directly starting the sterilization function after power-on.
For example, in order to achieve the sterilization effect, the interval duration of the two sterilizations is set to be 24 hours, and if 24 hours have elapsed since the last sterilization when the air handling unit is powered on, the sterilization function is started when the air handling unit is powered on. If the time length recorded by the air handling unit is 8 hours from the next start of the sterilization function when the power is off last time, the time length from the power on to the last power off is 2 hours, the real time length from the next start of the sterilization function after the power on is 6 hours, and the sterilization function is started after the air handling unit is powered on for 6 hours. Whether the sterilization function is started or not is irrelevant to whether the air handling unit operates or not, and is only relevant to the timing after the air handling unit is powered on. I.e. to sterilize every 24 hours regardless of whether the air handling unit is operating, as long as the air handling unit is in a powered-up state.
After the sterilization function is started, the intracavity temperature value and the intracavity relative humidity value of the air handling unit are obtained, and then the required sterilization duration is calculated according to the intracavity temperature value and the intracavity relative humidity value. And when the starting time of the ultraviolet germicidal lamp reaches the calculated germicidal time, closing the germicidal function.
Preferably, the step S200 of acquiring the intra-cavity temperature value and the intra-cavity relative humidity value of the air handling unit specifically includes:
Acquiring a plurality of temperature values in a cavity and a plurality of relative humidity values in the cavity, which are acquired within a preset time period, wherein the preset time period is a period of time before a sterilization function is started;
Calculating the average value of the temperature values to obtain the temperature value in the cavity;
And calculating the average value of the relative humidity values to obtain the relative humidity value in the cavity.
Specifically, in a preset time period before the sterilization function is started, temperature values and relative humidity values in the cavity of the air handling unit are collected for multiple times, then an average value of the collected temperature values is calculated to obtain an in-cavity temperature value, and an average value of the collected relative humidity values is calculated to obtain an in-cavity relative humidity value. For example, a plurality of temperature values and a plurality of relative humidity values, which are collected every 10s for three or five minutes before the ultraviolet germicidal lamp is turned on, are obtained, and then an average value of the plurality of temperature values and an average value of the plurality of relative humidity values are calculated. The intracavity average temperature value and the intracavity average relative humidity value in a period of time before the sterilization function is started are calculated, so that the intracavity temperature value and the intracavity relative humidity value are more accurate, and the sterilization effect is improved.
According to a third embodiment provided by the invention, a sterilization control method for an air handling unit comprises the following steps:
S100, after the air handling unit is powered on, judging whether a sterilization condition is met, if so, starting a sterilization function;
s200, acquiring an intra-cavity temperature value and an intra-cavity relative humidity value of the air handling unit;
S300, calculating sterilization duration according to the temperature value in the cavity and the relative humidity value in the cavity;
S400, when the starting time of the sterilization function reaches the sterilization time, closing the sterilization function;
Wherein, the step S300 of calculating the sterilization duration according to the intracavity temperature value and the intracavity relative humidity value specifically includes:
when T is1≤T≤T2and H is less than or equal to H1When t is t1；
when T is less than T1And H is less than or equal to H1When T is equal to (T)1-T)×a1+t1；
when T > T2And H is less than or equal to H1When T is (T-T)2)×a2+t1，a2＞a1；
When T is1≤T≤T2And H > H1when t is (H-H)1)×a3+t1，a1＞a3；
When T is less than T1And H > H1When T is equal to (T)1-T)×a1+t1+(H-H1)×a3；
when T > T2and H > H1when T is (T-T)2)×a2+t1+(H-H1)×a3；
Wherein T is the intracavity temperature value, T1Is a first predetermined temperature value, T2Is a second preset temperature value, H is the relative humidity value in the cavity, H1is a preset relative humidity value, t is the sterilization duration, t1For a first predetermined sterilization duration, a1Is a first predetermined coefficient, a2is a second predetermined coefficient, a3Is a third predetermined coefficient.
Specifically, when the ultraviolet germicidal lamp is used for sterilization, the sterilization effect is affected by overhigh or overlow temperature and humidity, and therefore, the sterilization duration needs to be calculated according to the temperature value and the relative humidity value in the cavity. The inventor finds that the ultraviolet germicidal lamp has the best germicidal effect when the temperature is in the range of 20-40 ℃ and the relative humidity is less than 60% in the research and development process, so that when the temperature value in the cavity is in the range of 20-40 ℃ and the relative humidity value in the cavity is less than or equal to 60%, the germicidal time length is determined as the shortest time length required by the sterilization. The shortest time required for sterilization is determined according to the interval time of two times of sterilization, if the sterilization is carried out once every 24 hours, the sterilization time of each time can be controlled within 30-60min according to the characteristics of the ultraviolet germicidal lamp, and the shortest time required for sterilization is 30 min. If the sterilization is performed every 48 hours, the sterilization duration of each time can be properly prolonged, for example, set to 45-75 min. If the sterilization is performed every 12 hours, the sterilization time of each time can be shortened appropriately, for example, set to 20-50 min.
If the set sterilization time is 30-60min, when the temperature value in the cavity is in the range of 20-40 ℃ and the relative humidity value in the cavity is less than or equal to 60%, the determined sterilization time is 30 min. When the temperature value in the cavity is less than 20 ℃ and the relative humidity value in the cavity is less than or equal to 60%, the sterilization time is (20-temperature value in the cavity) a1+30min, so as to properly prolong the sterilization time. When the temperature value in the cavity is more than 40 ℃ and the relative humidity value in the cavity is less than or equal to 60%, the sterilization duration is (temperature value in the cavity-40) × a2+30min, and a2 is more than a1, so that the sterilization duration is properly prolonged.
When the temperature value in the cavity is in the range of 20-40 ℃ and the relative humidity value in the cavity is more than 60%, the sterilization time is (relative humidity value in the cavity-60) multiplied by a3+30min, and a1 is more than a 3. And when the temperature value in the cavity is less than 20 ℃ and the relative humidity value in the cavity is more than 60%, the sterilization duration is (20-temperature value in the cavity) a1+30min + (relative humidity value in the cavity-60) x a 3. When the temperature value in the cavity is more than 40 ℃ and the relative humidity value in the cavity is more than 60%, the sterilization duration is (temperature value in the cavity-40) x a2+30min + (relative humidity value in the cavity-60) x a 3.
a1, a2 and a3 are respectively preset empirical coefficients, and in the scheme, when the sterilization duration is 30-60min each time, the value of a1 is 1.5, the value of a2 is 2, and the value of a3 is 1.
When the calculated sterilization duration is longer than the second preset sterilization duration, the second preset sterilization duration is set as the sterilization duration, the overlong sterilization duration is prevented from reducing the service life of the ultraviolet sterilization lamp, and meanwhile, other parts in the air treatment unit are prevented from being accelerated to age due to long-time ultraviolet irradiation. If the set sterilization time is 30-60min, the first preset sterilization time is 30min, and the second preset sterilization time is 60 min.
It should be understood that, in the foregoing embodiments, the sequence numbers of the steps do not mean the execution sequence, and the execution sequence of the steps should be determined by functions and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.
