The invention also provides an air conditioner sterilization control method, and referring to fig. 2, fig. 2 is a schematic flow chart of a first embodiment of the air conditioner sterilization control method of the invention.
In this embodiment, the air conditioner sterilization control method includes the following steps:
the invention provides an air conditioner sterilization control method applied to an air conditioner, wherein the air conditioner can comprise a compressor, an indoor unit, an electronic expansion valve and an outdoor unit. The compressor, the indoor unit, the electronic expansion valve and the outdoor unit are sequentially connected end to form a closed loop, the outdoor unit and the indoor unit further comprise heat exchangers, and actually the outdoor unit and the indoor unit are mainly used for heat exchange, so that the indoor unit can be an indoor heat exchanger, and the outdoor unit can be an outdoor heat exchanger. The electronic expansion valve is arranged between the indoor unit and the outdoor unit, is a throttling control element, is mainly used for limiting the flow and is used for regulating and controlling the flow of liquid flowing through the electronic expansion valve in the air conditioning system. The air conditioner electric auxiliary heating module is arranged in the air conditioner indoor unit and can convert electric energy into heat energy to provide heat energy for the air conditioner.
The heating principle of the air conditioner is as follows: when the air conditioner heats, the refrigerant in the air conditioner is pressurized by the compressor to become high-temperature and high-pressure gas, the high-temperature and high-pressure gas enters the heat exchanger (the condenser at the moment) of the indoor unit, the high-temperature and high-pressure gas is condensed, liquefied and released heat to become liquid refrigerant, and meanwhile, the indoor air is heated, so that the purpose of increasing the indoor temperature is achieved. Then, the liquid refrigerant is decompressed by the throttle device, enters a heat exchanger (an evaporator in this case) of the outdoor unit, absorbs heat of outdoor air (the outdoor air becomes cooler), evaporates and gasifies the liquid refrigerant, and absorbs heat to become a gas refrigerant.
Step S10, when the air conditioner is in the sterilization mode, determining whether the outdoor unit of the air conditioner is frosted;
in one embodiment, when the sterilization starting instruction is received, the air conditioner is controlled to enter a sterilization mode according to the sterilization starting instruction so as to control the air conditioner to execute sterilization operation. When the air conditioner is in the sterilization mode, whether the outdoor unit is frosted or not is determined by a temperature detection device installed at the outdoor unit of the air conditioner, or whether the outdoor unit is frosted or not is determined by a temperature detection device installed at the indoor unit of the air conditioner. It can be understood that when the temperature of the outdoor unit of the air conditioner is decreased to a certain temperature, it indicates that the outdoor unit of the air conditioner is frosted, and therefore, whether the outdoor unit of the air conditioner is frosted can be detected by the temperature detecting device installed in the outdoor unit of the air conditioner. In addition, since the frosting of the outdoor unit affects the heat exchange of the outdoor unit, thereby affecting the heating effect of the air conditioner and reducing the heating temperature of the air conditioner, the heating temperature in the air conditioner is detected by the temperature detection device installed in the indoor unit of the air conditioner, so as to indirectly detect whether the outdoor unit of the air conditioner is frosted. The temperature detecting device of the outdoor unit of the air conditioner can be arranged on the exhaust port of the outdoor unit and/or the pipe wall of the heat exchanger.
Further, when the air conditioner is powered on and started, the virus detection device and the bacteria concentration detection device are automatically started, whether a sterilization starting instruction is triggered or not is determined, so that the air conditioner is controlled to enter a sterilization mode, wherein the virus detection device is started to detect whether harmful viruses exist in the air conditioner or in the air or detect the virus density, and the bacteria concentration detection device is started to detect the bacteria concentration in the air conditioner or in the air. Therefore, when the air conditioner is powered on and started, the virus detection device and the bacteria concentration detection device are automatically started, so that the air conditioner can monitor the virus density or the bacteria concentration in the environment in real time. If harmful viruses exist in the air or the density of the viruses reaches a preset density or the concentration of bacteria in the air or in the air reaches a preset concentration, controlling a wind deflector driving motor in an indoor unit of the air conditioner to start, wherein the wind deflector driving motor is used for conveying high-temperature gas to an area with high virus density and an area with high bacteria concentration for sterilization; if harmful viruses exist in the air or the density of the viruses reaches a preset density or the concentration of bacteria in the air or in the air reaches a preset concentration, the air conditioner is controlled to heat, and the operation frequency of a compressor of the air conditioner is controlled to reach a preset frequency so as to improve the heating temperature to reach a preset heat degree.
Further, the step of performing the air conditioner to perform the sterilization operation may be: and controlling the air deflector to drive the motor to start and the compressor to start and heat. When the air deflector driving motor is switched to a target sterilization area, the air deflector driving motor is controlled to guide air left and right for a preset time period or guide air up and down for a preset time period or guide air left and right and up and down for a preset time period, so that high-temperature gas is conveyed to an area with high virus density and an area with high bacteria concentration for sterilization. The method comprises the following steps of controlling an air deflector to drive a motor to run at a first rotating speed for a first preset time; when the air guide plate runs at the first rotating speed for a first preset time, the air guide plate driving motor runs at a second rotating speed for a second preset time; and when the air guide plate runs at the second rotating speed for a second preset time, executing the step of controlling the air guide plate driving motor to run at the first rotating speed for the first preset time, and when the air guide plate driving motor runs at the first rotating speed for the first preset time, controlling the air guide plate driving motor to run at the second rotating speed for the second preset time so as to control the air speed of the air guide plate driving motor to circularly change from high air speed, low air speed and high air speed, thereby achieving better sterilization effect, wherein the first rotating speed is greater than the second rotating speed.
After the air conditioner is started, the air conditioner enters a corresponding mode according to requirements, for example, modes such as refrigeration, heating, dehumidification and disinfection are entered, in this embodiment, the first operation mode is a disinfection mode, and in this mode, an indoor unit of the air conditioner is disinfected to remove viruses and bacteria on the indoor unit or disinfect and disinfect surface attachments of the indoor unit, for example, surfaces of an indoor heat exchanger or bacteria generated in a humid environment due to accumulation of condensed water on the surfaces of the indoor heat exchanger.
For general viruses or bacteria, high temperature, for example, 40 degrees or 45 degrees, can be adopted to finish sterilization, but the sterilization and disinfection proposed by the application needs to be finished by breaking through the conventional control logic of the air conditioner for long time (30 minutes or 45 minutes) and high temperature (for example, temperature higher than 50 degrees or 56 degrees or 60 degrees) in addition to the sterilization of general bacteria.
After entering the first running mode, timing is started, and the timing operation is finished through a timer set by the air conditioner.
Controlling the air conditioner to adjust the operation parameters so as to enable the temperature generated by the action of the air conditioner to be increased to a first set temperature;
after entering the first operation mode, the air conditioner is controlled to adjust operation parameters, and the temperature generated by the action of the air conditioner is increased, wherein the generated temperature mainly aims at the temperature generated by the indoor unit, such as the temperature of an indoor heat exchanger, for example, the temperature of an indoor air outlet and the like. The raising to the first set temperature may be raising the temperature to the first set temperature, and the raising to the first set temperature may exceed the first set temperature as long as the temperature generated by the air conditioner is not lower than the first set temperature.
The first set temperature may be a specific value, for example, 56 degrees, 60 degrees or 65 degrees, or a temperature range, for example, 56 degrees to 65 degrees, or 56 degrees to 80 degrees, or 56 degrees to 100 degrees, or 60 degrees to 80 degrees, etc., and is set according to the temperature raising capability and/or sterilization requirement of the air conditioner, and the higher the temperature required by the type of virus or bacteria, the higher the set first set temperature; the higher the air conditioner's ability to increase temperature, the higher the first set temperature is set. After entering the first operation mode, the high temperature protection mode of the air conditioner stops operating, or the high temperature protection temperature is increased to 65 degrees or more than 70 degrees, and the increased temperature may be set as needed to enter the first operation mode. Under the condition that satisfies high-temperature sterilization, do not get into the high temperature protection and stop the operation of heating of air conditioner, promptly, under the outdoor high temperature's condition, this application also can get into and heat, raises the temperature.
The parameters of the air conditioner are controlled and adjusted, and the adjustment direction is to increase the temperature generated by the action of the air conditioner. The adjusted parameter may be one or more of the following parameters, which may be used to reduce the wind speed of the indoor fan, increase the frequency of the compressor, and reduce the opening of the electronic expansion valve.
And when the timing reaches a first set time, controlling the air conditioner to exit the first running mode.
After entering the first operation mode, the temperature generated by the air conditioner is controlled to be increased, for example, the temperature of the indoor heat exchanger reaches above 58 degrees, or the temperature of the air outlet of the indoor unit reaches above 56 degrees, or of course, the temperature of the indoor environment or the temperature of the air outlet of the indoor unit may be adjusted to be within a temperature range. And monitoring the duration of entering the first operation mode, and exiting the first operation mode when the timing reaches a first set time. After the first operation mode is exited, the operation can be switched to a second operation mode or stopped according to requirements. The first set time is the time from entering the first operation mode, namely entering the disinfection mode to exiting the disinfection mode, and may be 40 minutes, or 50 minutes, or 55 minutes, or may be a time range, for example, 45 minutes to 60 minutes, or 50 minutes to 70 minutes, etc., and the longer the disinfection time required by the virus or bacteria type is, the longer the set first set time is according to the performance of the air conditioner or the disinfection requirement; the stronger the air conditioner is capable of improving the temperature, the shorter the first set time is set, but the first set time is set according to the killing priority time, namely, the first set time set according to the air conditioner performance is shorter than the first set time set according to the killing priority time, and the first set time set according to the killing priority time is taken as the standard. When the air conditioner enters the first operation mode, the first operation mode is different from the ordinary cooling and heating mode, and is a high-temperature and high-pressure operation mode, the system pressure is very high, and the temperature which can be reached under the ordinary heating is difficult to exceed 50 ℃, so that the application needs to overcome the limitation of high-temperature and high-pressure in the existing air conditioner to increase the temperature to over 56 ℃, and the air conditioner is not an ordinary heating operation.
After exiting the first operation mode, the air conditioner is shut down or enters a second operation mode according to requirements; the second mode of operation may be one of cooling, heating or dehumidifying. When the first operation mode is switched to the second operation mode, the system pressure of the air conditioner needs to be released firstly, or heat needs to be released, otherwise, the indoor user is easily affected, for example, the angle of the air guide strip can be adjusted, the angle of the air guide strip is controlled to be upward for air supply, and the air supply is not performed at the position where the user exists indoors; when adjusting the wind-guiding angle, can control the compressor and stop the operation, also can control the air supply volume that increases indoor fan simultaneously for the circulation of air reduces indoor heat exchanger's temperature, reduces indoor air conditioner's system pressure.
In one embodiment, the layout information in the air conditioner action space is obtained; and determining the value of the first set temperature and/or the value of the first set time according to the layout information. Because the indoor fan for supplying air to the indoor is not closed, certain air quantity can be supplied to the indoor, the size of the indoor environment and the spatial layout can influence the design of the first set temperature and the first set time value, and the smaller the indoor environment is, the lower the first set temperature can be set; the first set time may be shorter, whereas a higher temperature or a longer time is required.
In other embodiments of the present application, when it is detected that the air conditioner is in the heating mode after exiting the disinfection mode, the first setting time may be increased, for example, increased by 5 minutes or 8 minutes, and the angle of the air guide strip is set according to the user position, that is, the air is supplied to the position farthest from the user position, so as to avoid the damage of the high-temperature air to the user, and the air supplied into the room is upward, and by supplying the high-temperature air, the air is higher than the air required for heating the room, the probability of the environmental bacteria inventory in the air conditioner is reduced. The increased time may be set according to the layout of the room and according to whether the user is moving or not, and if the user is moving and the direction is uncertain, the increased time may be shortened, or the room is small, the increased time may be shortened, and may be set to 1 minute or 2 minutes. Or before the air is switched to other modes, the air speed is increased and the air quantity sent into the indoor environment is increased so as to kill the air outlet or nearby air outlets and avoid polluting the indoor environment.
The mode of the first operation mode of air conditioner operation is controlled to the time for entering the first operation mode, the air conditioner parameters are adjusted, the temperature generated by the air conditioner action is increased to the first set temperature on the basis of the existing heating temperature, the indoor unit is sterilized by high temperature, viruses and air pollution are prevented from being sent into the indoor environment, and the comfort level of the air conditioner is improved.
In one embodiment, the step of controlling the air conditioner to adjust the operation parameter so as to increase the temperature generated by the action of the air conditioner to the first set temperature comprises the following steps:
reducing the rotating speed of an indoor fan of the air conditioner so as to increase the temperature generated by the action of the air conditioner to a first set temperature; the temperature generated by the air conditioner action comprises the temperature of an indoor heat exchanger of the air conditioner and/or the temperature of an air outlet of the air conditioner.
In this embodiment, it is preferable to reduce the indoor fan to increase the temperature to the first set temperature, where the rotation speed of the indoor fan is currently generally above 500 rpm, but in order to increase the temperature of the indoor heat exchanger of the air conditioner and/or the temperature of the air outlet of the air conditioner, the rotation speed of the indoor fan needs to be reduced to below 500 rpm, that is, the difficulty that the current rotation speed is above 500 rpm needs to be overcome, and the rotation speed of the fan needs to be reduced to 80 rpm-200 rpm or 100 rpm-200 rpm, which is greatly lower than the rotation speed of the fan that is used for cooling or heating. Through the rotational speed that reduces indoor fan, the heat that will heat the production remains in air conditioner indoor to avoid thermal loss, the temperature that improves air conditioner effect production that can be faster rises to first settlement temperature, the disinfection and sterilization of the indoor set of the start that is faster.
