step S400, when the difference value between the reference temperature and the disinfection temperature is larger than a preset difference value, adjusting the power of the electric auxiliary heating device so that the difference value is smaller than or equal to the preset difference value.
In the present embodiment, the execution body is an air conditioner. A temperature sensor is arranged in an air duct where an indoor heat exchanger in the air conditioner is located. The temperature sensor can be specifically arranged at the air outlet to detect the temperature of the air outlet, or the temperature sensor can be arranged at the indoor heat exchanger to detect the temperature of a coil of the indoor heat exchanger, or the temperature sensor can be arranged to detect the temperature of air in an air channel where the indoor heat exchanger is located. The air conditioner is also provided with a disinfection mode, the electric auxiliary heating device in the disinfection mode is always in an operating state, and the air conditioner automatically enters a heating mode.
The air conditioner is characterized in that the indoor heat exchanger of the air conditioner is provided with a temperature sensor, and the air temperature of an air channel where the indoor heat exchanger is located can be obtained through conversion of the coil temperature of the indoor heat exchanger collected by the temperature sensor and the power of the electric auxiliary heating device. Specifically, the air conditioner can determine the flow velocity of air in the air outlet duct through the rotating speed of the indoor fan, determine the heating energy of the air conditioner through the temperature of the coil pipe and the power of the electric auxiliary heating device, and determine the initial temperature of the air in the air outlet duct (the initial temperature can be detected by a temperature sensor of an indoor air return port), so that the air temperature of the air duct where the indoor heat exchanger is located is estimated according to the heating energy, the initial temperature, the flow velocity, the sectional area in the air outlet duct, the unit time and the heat exchange efficiency. It can be understood that the air conditioner does not need to be provided with an additional temperature sensor for detecting the air temperature of the air duct in which the indoor heat exchanger is located.
After the air conditioner starts the electric auxiliary heating device, the temperature collected by the temperature sensor is obtained, and the reference temperature is determined according to the temperature. If the temperature acquired by the temperature sensor is the coil temperature of the indoor heat exchanger, the reference temperature can be the coil temperature or the air temperature of the air duct in which the indoor heat exchanger is located, and the determination mode of the air temperature of the air duct in which the indoor heat exchanger is located refers to the above description; if the temperature collected by the temperature sensor is the air temperature of the air duct in which the indoor heat exchanger is located, the reference temperature is the air temperature of the air duct in which the indoor heat exchanger is located; and if the temperature collected by the temperature sensor is the temperature of the air outlet, the reference temperature is the temperature of the air outlet.
The air conditioner is provided with a disinfection temperature, the disinfection temperature can be a specific numerical value or a disinfection temperature range, and the disinfection temperature is different when the reference temperature is different. For example, if the reference temperature is the air temperature of the air duct in which the indoor heat exchanger is located, the sterilization temperature range is [56 ℃, 58 ℃). The air conditioner needs to judge whether the difference between the reference temperature and the disinfection temperature is larger than a preset difference, the difference is an absolute value, if the difference is larger than the preset difference, the power of the electric auxiliary heating device needs to be adjusted, and the difference between the disinfection temperature and the reference temperature is smaller than the preset difference. If the reference temperature is lower than the disinfection temperature and the difference between the reference temperature and the disinfection temperature is larger than a preset difference, the power of the electric auxiliary heating device needs to be increased; if the reference temperature is higher than the disinfection temperature and the difference between the reference temperature and the disinfection temperature is larger than the preset difference, the power of the electric auxiliary heating device needs to be reduced. If the sterilization temperature is within a range, the air conditioner needs to judge whether the reference temperature exceeds the sterilization temperature range. If the reference temperature is beyond the disinfection temperature range, the power of the electric auxiliary heating device needs to be adjusted to enable the reference temperature to be within the disinfection temperature range. Specifically, if the reference temperature is lower than the lower limit value of the disinfection temperature range, it indicates that the air conditioner does not reach the disinfection temperature, and at this time, the power of the electric auxiliary heating device needs to be increased to raise the reference temperature; if the reference temperature is greater than the upper limit value of the known temperature range, it indicates that the energy consumption of the air conditioner is too large, and at this time, the reference temperature needs to be reduced, that is, the power of the electric auxiliary heating device needs to be reduced to save the energy consumption of the air conditioner.
The air conditioner can regularly judge whether the reference temperature exceeds the disinfection temperature range, so that the power of the electric auxiliary heating device is regularly adjusted.
It should be noted that, when the air conditioner just enters the sterilization mode, the reference temperature is not in the sterilization temperature range, and at this time, the air conditioner controls the electric auxiliary heating device to operate according to the preset power, so that the temperature of the air duct where the indoor heat exchanger is located quickly reaches above the sterilization temperature, and the preset power is a larger power, so that the heating capacity of the electric auxiliary heating device is larger. In addition, the air conditioner can assist in increasing the reference temperature by operating the heating mode, and if the air conditioner enters the disinfection mode in the heating mode, the indoor fan is controlled to operate according to the preset rotating speed and the compressor is controlled to operate according to the preset frequency. The preset rotating speed is a lower rotating speed, so that the air flowing speed in the air outlet duct is lower, and the air can be fully heated; the preset frequency is a larger frequency, so that the indoor heat exchanger and the air in the air outlet duct can carry out large-amplitude heat exchange.
When the electric auxiliary heating device runs for a second preset time according to the preset frequency, the reference temperature is assumed to be greater than the disinfection temperature, and at the moment, the air conditioner acquires the reference temperature again to adjust the power of the electric auxiliary heating device according to the reference temperature. The second preset time period may be any suitable value, for example, 10min, and the second preset time period is less than the first preset time period.
In the technical scheme that this embodiment provided, the operation of the electric auxiliary heating device in the wind channel that indoor heat exchanger is located is controlled at the air conditioner, acquire the coil pipe temperature of indoor heat exchanger, the air outlet temperature or the air temperature in the wind channel that indoor heat exchanger is located in order to regard as reference temperature, if the difference of reference temperature and disinfection temperature is greater than and predetermines the difference, then the power of adjusting the electric auxiliary heating device makes the difference be less than or equal to and predetermine the difference between reference temperature and the disinfection temperature, thereby make the temperature in the wind channel maintain in suitable temperature range, make the air conditioner disinfect to the air under the condition of energy saving consumption.
Referring to fig. 4, fig. 4 is a third embodiment of the sterilization method of the air conditioner according to the present invention, and based on the second embodiment, the step S400 includes:
and S410, when the difference value between the reference temperature and the disinfection temperature is larger than a preset difference value, adjusting the power of the electric auxiliary heating device according to the difference value between the reference temperature and the disinfection temperature or a preset adjusting value.
In this embodiment, there are three ways to adjust the power of the electric auxiliary heating device.
The first is that the air conditioner adjusts the power of the electric auxiliary heating device according to the temperature difference between the reference temperature and the disinfection temperature, when the reference temperature is less than the disinfection temperature, the power of the electric auxiliary heating device is increased, and when the reference temperature is greater than the disinfection temperature, the power of the electric auxiliary heating device is reduced. The greater the temperature difference between the reference temperature and the sterilization temperature (the absolute value of the temperature difference), the greater the amplitude of the adjustment of the electric auxiliary heating means.
The second is that the air conditioner adjusts the power of the electric auxiliary heating device according to the fixed step number, namely the reference temperature is higher than the disinfection temperature, and the current power of the electric auxiliary heating device is reduced by the power corresponding to the fixed step number; and if the reference temperature is lower than the toxic temperature, increasing the current power of the electric auxiliary heating device by the power corresponding to the fixed step number.
Thirdly, the air conditioner adjusts the power of the electric auxiliary heating device according to the power percentage, wherein the power percentage can be a fixed percentage, namely the reference temperature is higher than the toxic temperature, and the current power of the electric auxiliary heating device is reduced by the power corresponding to the power percentage; and if the reference temperature is lower than the toxic temperature, increasing the current power of the electric auxiliary heating device by the power corresponding to the power percentage. Of course, the power percentage may also be determined by the temperature difference in the first way, the greater the absolute value of the temperature difference, the greater the power percentage.
It will be appreciated that the preset adjustment value may include a power percentage and a number of steps, or only a number of steps.
In the technical scheme provided by the embodiment, the air conditioner accurately adjusts the power of the electric auxiliary heating device according to the temperature difference between the reference temperature and the disinfection temperature or the preset adjustment value.
Referring to fig. 5, fig. 5 is a fourth embodiment of the sterilization method of the air conditioner according to the present invention, and based on the third embodiment, the step S410 includes:
step S411, when the reference temperature is lower than the disinfection temperature, determining the target power of the electric auxiliary heating device according to the difference value between the reference temperature and the disinfection temperature or a preset adjusting value;
step S412, when the target power is less than or equal to the maximum power of the electric auxiliary heating device, controlling the electric auxiliary heating device to operate according to the target power;
and step S413, when the target power is larger than the maximum power of the electric auxiliary heating device, controlling the electric auxiliary heating device to operate according to the maximum power, and reducing the rotating speed of the indoor fan, increasing the operating frequency of the compressor and/or reducing the opening degree of the electronic expansion valve.
In this embodiment, the air conditioner operates in a heating mode and a sterilization mode at the same time. The power of the electric auxiliary heating device is continuously changed because the air conditioner adjusts the power of the electric auxiliary heating device at certain intervals. When the reference temperature is lower than the disinfection temperature, the power of the electric auxiliary heating device needs to be increased, but the power of the electric auxiliary heating device may reach the maximum value, so that the air conditioner cannot raise the reference temperature to disinfect the air, and the air conditioner needs to take other measures to raise the reference temperature.
Specifically, the air conditioner determines a power increase value according to a temperature difference value between the reference temperature and the sterilization temperature or a preset adjustment value, and obtains the target power of the electric auxiliary heating device through the power increase value and the current power of the electric auxiliary heating device. The air conditioner judges whether the target power is larger than the maximum power of the electric auxiliary heating device.
If the target power is larger than the maximum power of the electric auxiliary heating device, the air conditioner firstly controls the electric auxiliary heating device to operate according to the maximum power, and at least one of three modes of reducing the rotating speed of the indoor fan, increasing the frequency of the compressor and reducing the opening degree of the electronic expansion valve is executed to improve the reference temperature. The reduction of the rotating speed of the indoor fan can reduce the flow velocity of air in the air outlet duct, so that the reference temperature can be increased; the increase of the frequency of the compressor can enable the temperature of a coil of the indoor heat exchanger to rise, and can also increase the reference temperature; and the opening degree of the electronic expansion valve is reduced, so that the temperature of the coil pipe of the indoor heat exchanger can be increased, and the reference temperature is further increased. The adjustment amplitudes of the three modes are determined according to the power difference between the target power and the maximum power, and the larger the power difference is, the larger the adjustment amplitude is.
And if the target power is less than or equal to the maximum power of the electric auxiliary heating device, controlling the electric auxiliary heating device to operate according to the target power.
In the technical scheme provided by this embodiment, if the reference temperature is less than the sterilization temperature, the air conditioner determines the target power of the electric auxiliary heating device, and if the target power is greater than the maximum power of the electric auxiliary heating device, the rotation speed of the indoor fan is reduced, the operating frequency of the compressor is increased, and/or the opening degree of the electronic expansion valve is reduced, so as to ensure that the air conditioner can reach the sterilization temperature to sterilize the air.
Referring to fig. 6, fig. 6 is a fifth embodiment of the sterilization method of the air conditioner according to the present invention, and based on the third embodiment, the step S410 includes:
step S414, when the reference temperature is higher than the disinfection temperature, determining the target power of the electric auxiliary heating device according to the difference value between the reference temperature and the reference temperature or a preset adjusting value;
step S415, when the target power is greater than the minimum power of the electric auxiliary heating device, controlling the electric auxiliary heating device to operate according to the target power;
and S416, when the target power is less than or equal to the minimum power of the electric auxiliary heating device, controlling the electric auxiliary heating device to operate according to the minimum power, and increasing the rotating speed of the indoor fan, reducing the operating frequency of the compressor and/or increasing the opening of the electronic expansion valve.
In this embodiment, the air conditioner operates in a heating mode and a sterilization mode at the same time. The power of the electric auxiliary heating device is continuously changed because the air conditioner adjusts the power of the electric auxiliary heating device at certain intervals. When the reference temperature is higher than the disinfection temperature, the power of the electric auxiliary heating device needs to be reduced, but the power of the electric auxiliary heating device may reach the minimum value, so that the air conditioner cannot reduce the reference temperature to save energy consumption, and the air conditioner needs to take other measures to reduce the reference temperature. The minimum value may be set by the user.
Specifically, the air conditioner determines a power reduction value according to a temperature difference value between the reference temperature and the sterilization temperature or a preset adjustment value, and obtains the target power of the electric auxiliary heating device through the power reduction value and the current power of the electric auxiliary heating device. The air conditioner then judges whether the target power is less than or equal to the minimum power of the electric auxiliary heating device.
If the target power is less than or equal to the minimum power of the electric auxiliary heating device, the air conditioner firstly controls the electric auxiliary heating device to operate according to the minimum power, and at least one of three modes of increasing the rotating speed of the indoor fan, reducing the frequency of the compressor and increasing the opening degree of the electronic expansion valve is executed to increase the reference temperature. The increase of the rotating speed of the indoor fan can improve the flow velocity of the air in the air outlet duct, so that the reference temperature can be reduced; the reduction of the frequency of the compressor can reduce the temperature of the coil of the indoor heat exchanger and also can reduce the reference temperature; and the opening degree of the electronic expansion valve is increased, so that the temperature of the coil pipe of the indoor heat exchanger can be reduced, and the reference temperature is further reduced. The adjustment amplitudes of the three modes are determined according to the power difference between the target power and the minimum power, and the larger the power difference is, the larger the adjustment amplitude is.
And if the target power is greater than the minimum power of the electric auxiliary heating device, controlling the electric auxiliary heating device to operate according to the target power.
In the technical solution provided in this embodiment, if the reference temperature is greater than the sterilization temperature, the air conditioner determines the target power of the electric auxiliary heating device, and if the target power is less than or equal to the minimum power of the electric auxiliary heating device, the rotation speed of the indoor fan is increased, the operating frequency of the compressor is reduced, and/or the opening of the electronic expansion valve is increased, so that the energy consumption of the air conditioner is reduced in advance when the air conditioner can achieve sterilization.
Referring to fig. 7, fig. 7 shows a sixth embodiment of the sterilization method for an air conditioner according to the present invention, wherein after step S300, the method further includes:
and S500, when the difference value between the reference temperature and the disinfection temperature is smaller than or equal to a preset difference value, increasing the rotating speed of the indoor fan and the running frequency of the compressor.
In this embodiment, the air conditioner simultaneously operates a heating mode and a sterilization mode. When the difference between the reference temperature and the disinfection temperature is smaller than or equal to the preset difference, the air conditioner can sterilize the air in the air duct, and at the moment, the air conditioner can improve the rotating speed of the indoor fan, so that the air conditioner can convey the sterilized air farther, and the sterilization of the air conditioner to the indoor air can be accelerated. However, the reference temperature is inevitably reduced due to the increase of the rotating speed of the indoor fan, and therefore, the air conditioner can increase the operating frequency of the compressor while increasing the rotating speed of the indoor fan so as to avoid the reduction of the reference temperature when the rotating speed of the indoor fan is increased.
The increase in the operating frequency of the compressor is associated with the increase in the rotational speed of the indoor fan. When the rotating speed of the indoor fan is increased, the reference temperature is reduced, so that the rotating speed increment value of the indoor fan can be determined according to the temperature difference between the reference temperature and the disinfection temperature. The air conditioner estimates the rotation speed of the indoor fan to increase according to the rotation speed increment value and the current rotation speed of the indoor fan, then refers to the descending amplitude of the temperature, and calculates the frequency increment value of the compressor according to the descending amplitude, so that the indoor fan is controlled to increase the rotation speed according to the rotation speed increment value, and the compressor is controlled to increase the running frequency of the compressor according to the frequency increment value.
Furthermore, after the rotating speed of the indoor fan is increased, the air conditioner can control the air deflector to rotate so as to sweep air indoors, and therefore the indoor is disinfected in an all-around manner.
In the technical scheme that this embodiment provided, when confirming that the difference in temperature of reference temperature and disinfection temperature is less than preset difference, the rotational speed of increase indoor fan and the frequency of compressor for the reference temperature of air conditioner maintains under the advance of disinfection temperature range, disinfects the disinfection to indoor air fast, and can send the air after disinfecting farther.
Referring to fig. 8, fig. 8 is a simplified flowchart of a sterilization method of an air conditioner according to the present invention. The air conditioner starts a disinfection mode to perform high-temperature sterilization after receiving a disinfection instruction, and starts timing; the air conditioner runs a heating mode in a running disinfection mode, a four-way valve is opened in the heating mode, an indoor fan runs at R rpm, a compressor fo runs at a T4 frequency limit frequency, T4 is the outdoor environment temperature, the frequency limit frequency of the compressor is determined by T4, and electric auxiliary heat runs at preset power; after the electric auxiliary heating operation is performed for T1(T1 can be 10min), the temperature of an air duct of the indoor unit T2 (the temperature of an air duct where the indoor heat exchanger is located) is obtained to judge whether the temperature is [ T1, Th ], wherein T1 can be 56 ℃ and Th can be 58 ℃.
If the temperature T2 is less than or equal to T1, increasing the power of the electric auxiliary heat for 3min, wherein the power of the electric auxiliary heat can be increased by a fixed K step, the difference between T1 and T2 or the percentage of the rated steps; and if the electric auxiliary heating power is increased to the maximum, reducing the rotating speed of the indoor fan, increasing the frequency of the compressor or reducing the opening of the electronic expansion valve.
If the temperature T2 is greater than or equal to T1, the power of the electric auxiliary heat is reduced for 3min, and the power of the electric auxiliary heat can be reduced by a fixed K step, the difference between T1 and T2 or the percentage of the rated steps; and if the electric auxiliary heating power is reduced to the minimum, increasing the rotating speed of the indoor fan, reducing the frequency of the compressor or opening the electronic expansion valve.
If the temperature T2 is between (T1, Th), the operation is continued for 5 min.
