With reference to fig. 1, an embodiment of the present disclosure provides a method for controlling heating of an inter-train air conditioner, including:
s101, detecting the current indoor environment temperature by a temperature sensor.
And S102, determining the working modes and the heating stages of all the electric heaters by the processor according to the relation among the indoor environment temperature, the target temperature and the set temperature of the control dead zone. The working modes comprise a loading mode and a unloading mode, and the heating stages are used for representing the switch states of all the electric heaters.
And S103, controlling the corresponding electric heater to operate by the processor according to the working mode and the heating stage number.
Here, the inter-row air conditioner operation heating mode detects the current indoor ambient temperature through a temperature sensor of the indoor or inter-row air conditioner. Meanwhile, a target temperature set by a user and a set temperature of a control quiet zone are obtained. The target temperature and the set temperature of the control quiet zone can be set through a touch screen of an upper computer or an air conditioner between columns. The set range of the target temperature is generally 8-30 ℃, and the target temperature can be 19 ℃ if the target temperature can be set. The set temperature of the quiet zone is controlled to be in the range of 0.2-10 ℃, for example, the set temperature can be 3 ℃. The control of the dead zone refers to controlling the inter-row air conditioner (heating equipment in a heating mode) and indoor refrigerating equipment to jointly act to maintain the environment within a temperature range in the temperature control process. For example, in a machine room environment, heat is generated by the operation of a host in the machine room, and the heat is dissipated by the inter-row air conditioner, so that the two work together to maintain the ambient temperature. In this process, there are a cooling output zone, a heating output zone, and a neutral zone (a cold and hot air flow mixing zone, i.e., a control quiet zone) in the room environment.
Further, the working mode and the heating stage number of the heater are determined by combining the current indoor environment temperature, the target temperature and the set temperature of the control dead zone. The working modes comprise a loading mode and a load shedding mode, and the loading stage number is used for representing the switch states of all the electric heaters. Here, the operation mode and the number of heating stages are for all electric heaters, not for one or some electric heaters. As an example, the electric heaters are three and the number of the electric heaters currently in heating operation is 1, and determining the loading mode of the electric heaters means turning on one or two of the other two electric heaters. By analogy, the load shedding mode is to turn off one or more of the electric heaters that are on. Likewise, the heating progression characterizes the switching state of all electric heaters. As an example, Li denotes a heating order, i denotes different orders, and the electric heaters include a first electric heater and a second electric heater. It can be represented by L0 that both the first and second electric heaters are off. L1 indicates that the first electric heater is on and the second electric heater is off. L2 indicates that both the first and second electric heaters are operating. The higher the level of the heating stage, the greater the number of electric heaters it operates. Therefore, the current indoor environment temperature condition can be determined through the relationship of a plurality of temperature parameters, and the working mode and the heating stage number of the electric heater can be further determined. It is understood that the indoor ambient temperature is less than the target temperature and that the electric heater is required to provide more heat when the difference is larger. That is, the operation mode of the electric heater is the loading mode, and the higher the level of the heating stage is. Likewise, when the indoor ambient temperature is greater than or equal to the target temperature, or the indoor ambient temperature is less than the target temperature, but the difference is small, the thermal energy demand on the electric heater is reduced. That is, the operation mode of the electric heater is the load shedding mode, and the lower the level of the heating stage is.
By adopting the method for controlling the heating of the air conditioner between the columns, provided by the embodiment of the disclosure, the working modes and the heating stages of all the electric heaters can be determined based on the relation between the indoor environment temperature, the target temperature and the set temperature of the control dead zone during rapid heating. Thereby controlling the operation of the opposite electric heaters. Therefore, the indoor environment temperature is more accurately adjusted; meanwhile, the working mode and the heating stage number of the electric heater can be accurately controlled conveniently. So that the indoor ambient temperature can quickly reach the target temperature.
Optionally, in step S102, the processor determines the working modes and the heating stages of all the electric heaters according to the relationship between the indoor environment temperature, the target temperature and the set temperature of the control quiet zone, including:
and S121, calculating the difference value between the target temperature and the indoor environment temperature by the processor.
And S122, determining the working mode and the heating stage number of the electric heater by the processor according to the difference and the set temperature of the control dead zone.
Here, the difference Δ T is Ts — Tao, Ts is the target temperature, and Tao is the indoor ambient temperature. As can be appreciated, the inter-train air conditioning operation heating mode is only enabled when Δ T ≧ the third threshold. Wherein the third threshold may take the value zero. And then, determining the working mode of the electric heater according to the difference and the set temperature of the control dead zone. Generally, if the difference is greater than the set temperature of the control dead zone, it indicates that the current indoor ambient temperature is greatly different from the target temperature. At this time, the operation mode of the electric heater is a loading mode, that is, the heat output of the electric heater is increased. And if the difference value is less than the set temperature of the control quiet zone, determining the working mode of the electric heater according to the difference value of the two temperatures. Specifically, the smaller the temperature difference between the two is, the more the current indoor ambient temperature approaches the target temperature. The operating mode of the electric heater may be a de-rate mode, i.e. reducing the heat output of the electric heater. When the temperature difference between the two is larger, the working mode of the electric heater can be determined as the loading mode. The heat output of the electric heater is increased to enable the indoor ambient temperature to quickly approach the target temperature.
Optionally, in step S122, the processor determines an operation mode of the electric heater according to the difference and the set temperature of the control dead zone, including:
the processor determines the operation mode of the electric heater as the load shedding mode in a case where a ratio of the difference to the set temperature of the control dead zone is less than or equal to a first threshold value.
The processor determines that the working mode of the electric heater is a loading mode under the condition that the ratio is greater than or equal to a second threshold value; wherein the second threshold is greater than the first threshold.
Here, the ratio of the difference between the target temperature and the indoor ambient temperature and the set temperature of the control dead zone is calculated, and a threshold value is set to define the magnitude of the ratio. Specifically, when the ratio is less than or equal to the first threshold, it indicates that the current indoor ambient temperature is close to the target temperature. Therefore, the electric heater can be appropriately unloaded. On one hand, the waste of resources is avoided, and on the other hand, the situation that the indoor temperature exceeds the target temperature due to the adjustment hysteresis is avoided, and indoor related equipment is influenced. When the ratio is larger than or equal to the second threshold value, the current indoor environment temperature is indicated to deviate from the target temperature greatly. At this time, the electric heater needs to be loaded to accelerate the increasing rate of the indoor temperature, so as to realize rapid heating. Wherein the second threshold value can take a value of 0.5; the first threshold may take the value 0.4.
Optionally, there is one electric heater; step S122, the processor determines the heating level of the electric heater according to the difference and the set temperature of the control dead zone, and the step S comprises the following steps:
when the operation mode of the electric heater is the load reduction mode, the processor determines that the heating levels Li of all the electric heaters are L0.
And the processor determines the heating level Li of all the electric heaters to be L1 under the condition that the working mode of the electric heaters is the loading mode.
Here, in the case where there is only one electric heater, the number of heating stages is only two. The heating stage number is high during loading, and the electric heater is operated. When the load is reduced, the grade of the heating grade is low, and the electric heater is closed. Further, if the load of the air conditioner between the columns is not sufficiently supported because only one electric heater is used, if the load reduction is performed according to the above-described determination condition, the indoor ambient temperature cannot reach the target temperature for a long time. To avoid this, when the load shedding condition is corrected so that the difference between the target temperature and the indoor ambient temperature is smaller than the third threshold (the third threshold may take a value of 0), the load shedding is performed when there is only one electric heater. That is, after the indoor ambient temperature reaches the target temperature, the electric heater is turned off.
Optionally, the electric heater is plural; step S122, the processor determines the heating level of the electric heater according to the difference and the set temperature of the control dead zone, and the step S comprises the following steps:
in the case where the operation mode of the electric heater is the load shedding mode, the smaller the ratio, the lower the level of the heating steps of all the electric heaters.
In the case where the operation mode of the electric heaters is the loading mode, the larger the ratio is, the higher the level of the heating stages of all the electric heaters is.
Here, the plurality of electric heaters are the same in model, i.e., there is no difference between the electric heaters. In the unloaded mode, the smaller the ratio, the lower the level of the heating stage. I.e. the fewer the number of heaters that are on. In the loading mode, the larger the ratio, the higher the level of the heating stage, i.e., the greater the number of heaters that are turned on for operation.
Further, in order to improve the matching degree between the heating stages and the indoor ambient temperature, the heating stages may be divided according to the number of the electric heaters. Meanwhile, the ratio division is refined to match with the heating stage number. As one example, the electric heater includes a first electric heater and a second electric heater. In the load shedding mode, a third threshold (the value range is detailed in the foregoing), and when the ratio is smaller than or equal to the first threshold and larger than the third threshold, the heating level Li is L1, which indicates that the first electric heater or the second electric heater is operated, and the other electric heater is turned off. In the case where the ratio is less than or equal to the third threshold value, the heating level Li — L0 indicates that both the first electric heater and the second electric heater are off. In the loading mode, a fourth threshold value is set, and in the case where the ratio is greater than or equal to the second threshold value and less than the fourth threshold value, the heating stage number Li is L1, which indicates that the first electric heater or the second electric heater is operated and the other electric heater is turned off. In the case where the ratio is greater than or equal to the fourth threshold value, the heating stage number Li ═ L2 indicates that both the first electric heater and the second electric heater are operating. Wherein the fourth threshold may take the value 1. By analogy, the heating order can be determined for a plurality of electric heaters.
Optionally, the heating powers of the plurality of electric heaters are different, and in step S122, the processor determines the heating stages of the electric heaters according to the difference and the set temperature of the control dead zone, including:
in the case where the operation mode of the electric heater is the load shedding mode and the ratio is smaller, the level of the heating stage number is lower as the heating power of the electric heater is larger.
In the case where the operation mode of the electric heater is the loading mode and the ratio is larger, the heating power of the electric heater is larger, and the level of the heating stage number is higher.
Here, when the heating powers of the plurality of electric heaters are different, different electric heaters are turned on to generate different heat energies. Thus, the level of the heating progression is determined based on the ratio and the heating power. The grade of the heating series not only represents the number of the electric heaters which are started to operate, but also represents the heating power of the electric heaters. As an example, the electric heater includes a first electric heater and a second electric heater, and the heating power of the first electric heater is smaller than the heating power of the second electric heater. Meanwhile, a fifth threshold and a sixth threshold are set, for example, the value of the fifth threshold is 0.2, and the value of the sixth threshold is 0.8. In the load shedding mode, when the ratio is smaller than or equal to the first threshold and greater than the fifth threshold, the heating level Li is L2, which indicates that the first electric heater is turned off and the second electric heater is operated. When the ratio is less than or equal to the fifth threshold and greater than the third threshold, the heating level Li is L1, which indicates that the second electric heater is turned off and the first electric heater is operated. When the ratio is less than or equal to the third threshold, the heating level Li is L1, which indicates that both the first and second electric heaters are turned off. Likewise, in the loading mode, when the ratio is greater than or equal to the second threshold and less than the sixth threshold, the heating level Li is L1, which indicates that the second electric heater is turned off and the first electric heater is operated. When the ratio is greater than or equal to the sixth threshold and less than the fourth threshold, the heating level Li is L2, which indicates that the first electric heater is turned off and the second electric heater is operated. When the ratio is greater than or equal to the fourth threshold, the heating stage number Li equals L3, which indicates that both the first and second electric heaters are operated. Like this, under to different heating demands, appoint different heating progression for indoor heating control is more rapid and accurate.
Optionally, in step S101, the detecting, by a temperature sensor, a current indoor ambient temperature includes: the temperature sensor detects the outlet air temperature or the return air temperature of the air conditioner between the rows. In order to improve the control precision, the outlet air temperature or the return air temperature of the air conditioner between the columns is detected, and the situation that the temperature of each indoor area is different due to cold and hot air flows in the room, so that the detection parameters are greatly different is avoided.
