Referring to fig. 1, fig. 1 is a schematic flow chart illustrating a method for controlling an odor prevention of an air conditioner according to an embodiment of the present invention. The following describes the method for controlling the odor of the air conditioner in detail. As shown in fig. 1, the method includes the following steps S110-S130.
And S110, detecting whether the peculiar smell prevention starting condition is met according to the acquired indoor environment temperature, the set temperature and the inner pipe temperature.
In the embodiment of the invention, after the air conditioner is powered on, the indoor environment temperature setting temperature and the inner pipe temperature are obtained, wherein the inner pipe temperature is the temperature on the evaporator of the indoor unit of the air conditioner; and detecting whether the peculiar smell prevention starting condition is met or not according to the indoor environment temperature, the set temperature and the inner pipe temperature. Specifically, a difference between the indoor ambient temperature and the set temperature is calculated to obtain a first temperature difference; and detecting whether the peculiar smell prevention starting condition is met or not according to the first temperature difference and the temperature of the inner pipe.
In some embodiments, such as the present embodiment, as shown in fig. 2, the step S110 may include steps S111-S112.
S111, calculating the difference between the indoor environment temperature and the set temperature to obtain a first temperature difference;
and S112, if the first temperature difference is smaller than a first preset temperature difference threshold value and the temperature of the inner tube is larger than a preset inner tube temperature threshold value, judging that the peculiar smell prevention starting condition is met.
In the embodiment of the present invention, for the convenience of description, it is assumed that the indoor ambient temperature is T Indoor ambient temperature The set temperature is T Set temperature The temperature of the inner tube is T Temperature of inner tube The first temperature difference is DeltaT 1, calculate (T) Indoor ambient temperature -T Set temperature ) = Δ T1, determining whether Δ T1 is smaller than a first preset temperature difference threshold, wherein the first preset temperature difference threshold is 1.5 ℃, if Δ T1 is smaller than the first preset temperature difference threshold<At 1.5 deg.C, continuing to judge T Temperature of inner tube Whether the temperature is greater than a preset inner tube temperature threshold value or not, wherein the preset inner tube temperature threshold value is 5 ℃, and if T is greater than the preset inner tube temperature threshold value Temperature of inner tube >And 5 ℃, judging that the peculiar smell prevention starting condition is met. That is, in the present embodiment, when Δ T1<1.5 ℃ and T Temperature of inner tube >And when the temperature is 5 ℃, judging that the peculiar smell preventing starting condition is met, and automatically entering a peculiar smell preventing program by the air conditioner to start the peculiar smell preventing function. Understandably, if the first temperature difference is greater than or equal to the first preset temperature difference threshold or the inner tube temperature is less than or equal to the preset inner tube temperature threshold, namely if the delta T1 is greater than or equal to 1.5 ℃ or T Temperature of inner tube And if the temperature is less than or equal to 5 ℃, judging that the peculiar smell preventing starting condition is not met, and entering a conventional control program at the moment. In this embodiment, Δ T1 is defined as<When the temperature reaches 1.5 ℃, the temperature is judged to reach a temperature point so as to avoid the absorption of hydrophilic aluminum foil on the evaporator in the shutdown process of the compressorThe moisture in the air is absorbed and then the acid odor is emitted, namely the generation of the peculiar smell is prevented. It should be further noted that, in other embodiments, the first preset temperature difference threshold and the preset inner tube temperature threshold may be set according to actual requirements, and are not limited herein.
And S120, if the peculiar smell prevention opening condition is met, closing the electromagnetic valve, and adjusting the frequency of the compressor and the opening degree of the electronic expansion valve to obtain the open-loop operation frequency and the open-loop operation opening degree.
In the present embodiment, if Δ T1<1.5 ℃ and T Temperature of inner tube >And 5 ℃, controlling the electromagnetic valve to close in an attracting mode when the peculiar smell preventing condition is met, wherein at the moment, an inlet 1 and an inlet are closed, only an inlet 3 and an inlet 4 can pass through a refrigerant, the evaporation area of an evaporator in the indoor unit is reduced, the output cold quantity of the air conditioner is reduced, and the compressor and the electronic expansion valve simultaneously enter open-loop control, namely the frequency of the compressor and the opening degree of the electronic expansion valve are adjusted to obtain the open-loop operation frequency and the open-loop operation opening degree as shown in figure 3. Specifically, adjusting the frequency of the compressor to be half of the current operating frequency to obtain an open-loop operating frequency; and adjusting the opening degree of the electronic expansion valve to be half of the current operation opening degree to obtain the open-loop operation opening degree. For ease of understanding, assume that the current operating frequency of the compressor is F Current operating frequency The current operation opening degree of the electronic expansion valve is P Current operation opening degree If the open-loop operation frequency is F and the open-loop operation opening is P, F = F Current operating frequency /2；P＝P Current running aperture /2. It should be noted that, in this embodiment, the reason why the frequency of the compressor and the opening degree of the electronic expansion valve are adjusted is that the closing of the inlet 1 and the inlet 2 reduces the evaporation area, so that the frequency of the compressor and the opening degree of the electronic expansion valve are correspondingly reduced, and the excessive pressure and the excessive cooling output of the air conditioner system are avoided. In practical application, the stage of regulating and operating the frequency of the compressor and the opening of the electronic expansion valve is called an open-loop control stage, and the purpose of the open-loop control of the air conditioner is that the area of an evaporator suddenly changes and the compressor needs to operate at a low frequencyAnd (3) the system is stably operated for a period of time, and the phenomenon that the frequency of the compressor and the opening degree of the electronic expansion valve are adjusted excessively due to sudden change of area is avoided.
And S130, after the running time is preset, adjusting the open-loop running frequency and the open-loop running opening according to the inner tube temperature and the acquired dew point temperature.
In the embodiment of the invention, after the air conditioner operates for a preset operation time in an open-loop control stage, the air conditioner can adjust the open-loop operation frequency and the open-loop operation opening according to the temperature of the inner pipe and the acquired dew point temperature, wherein the preset operation time is 3min. Understandably, in other embodiments, the preset operation time can be set to other values, for example, 5min, according to the actual requirement. It should be noted that, in this embodiment, it is assumed that the dew point temperature is T _ dew, and a specific calculation formula of T _ dew is T _ dew = f (T _ dew = f) Indoor ambient temperature ，RH Indoor )＝[(156×T Indoor ambient temperature +17075)×RH Indoor -preset dew passing limit + (870 × T) Indoor ambient temperature -16863)]/1024, wherein, RH Indoor The preset condensation allowable limit value is a value set according to actual requirements for the indoor environment humidity.
In some embodiments, such as this embodiment, as shown in FIG. 4, the step S130 may include steps S131-S134.
S131, acquiring a dew point temperature, and calculating the difference between the temperature of the inner pipe and the dew point temperature to obtain a second temperature difference;
s132, judging whether the second temperature difference is smaller than a second temperature difference threshold value, if so, executing a step S133, otherwise, executing a step S134;
s133, keeping the open-loop operation frequency and the open-loop operation opening unchanged;
and S134, controlling the open-loop operation frequency to increase at a preset frequency, and controlling the open-loop operation opening to increase at a preset opening.
In the embodiment of the invention, the dew point temperature T _ dew is obtained, andcalculating the temperature T of the inner tube Temperature of inner tube And the difference between said dew point temperatures T _ dews yields a second temperature difference Δ T2, understandably, Δ T2= (T =) Temperature of inner tube -T _ ew); determining whether Δ T2 is less than a second temperature difference threshold, wherein, the second temperature difference threshold is 0 if Δ T2<0, keeping the open-loop operation frequency and the open-loop operation opening unchanged; and if the delta T2 is larger than or equal to 0, controlling the open-loop operation frequency to increase by a preset frequency, and controlling the open-loop operation opening to increase by a preset opening, wherein the preset frequency is 1Hz/60s, and the preset opening is 3B larger every 10 s. Specifically, the open-loop operation frequency is controlled to be slowly increased by 1Hz/60s, and the open-loop operation opening is controlled to be increased by 3B at 10 s. More specifically, at the first 10s, the open-loop operation opening is increased by 3B, at the second 10s, the open-loop operation opening is increased by 3B again, at this time, 6B is increased in total, and so on, understandably, at the first 60s, the open-loop operation frequency is increased by 1Hz, at the second 60s, the open-loop operation frequency is increased by 1Hz again, and so on. It should be noted that, in this embodiment, when Δ T2 is greater than or equal to 0, that is, when the temperature of the inner tube is greater than the dew point temperature, the open-loop operating frequency and the open-loop operating opening are adjusted, because when Δ T2 is greater than or equal to 0, condensed water begins to volatilize and is diffused into the air, and the hydrophilic aluminum foil absorbs moisture in the air and then emits acid odor, and therefore, in order to prevent generation of odor, the open-loop operating frequency and the open-loop operating opening need to be increased. It should be further noted that, in other embodiments, the second temperature difference threshold, the preset frequency, and the preset opening may all be set according to actual requirements, and are not specifically limited herein.
Referring to fig. 5, fig. 5 is a schematic flowchart illustrating steps of a control method for preventing odor of an air conditioner according to another embodiment of the present invention, the control method includes steps S210 to S250, wherein steps S210 to S230 are the same as steps S110 to S130, and steps S240 and S250 added after step S230 are emphasized. S240, detecting whether an odor-resistant closing condition is met or not according to the first temperature difference and the temperature of the inner pipe;
and S250, if the peculiar smell prevention closing condition is met, controlling the electromagnetic valve to be opened, and entering a preset conventional control program.
In the embodiment of the invention, after the open-loop operation frequency and the open-loop operation opening degree are adjusted according to the temperature of the inner pipe and the dew point temperature, whether an odor-resistant closing condition is met or not is detected according to the first temperature difference and the temperature of the inner pipe; if the odor-resistant closing condition is met, the electromagnetic valve is controlled to be opened, a preset conventional control program is entered, and understandably, if the odor-resistant closing condition is not met, the step of adjusting the open-loop operation frequency and the open-loop operation opening according to the inner tube temperature and the acquired dew point temperature is returned to, namely, the step S230 is returned to. Specifically, as mentioned above, the first temperature difference is Δ T1, the first preset temperature difference threshold is 1.5 ℃, and the inner tube temperature is T Temperature of inner tube And presetting the temperature threshold of the inner tube to be 5 ℃, judging whether delta T1 is less than 1.5 ℃, and if delta T1 is less than 1<At 1.5 deg.C, continuing to judge T Temperature of inner tube If T is greater than 5 deg.C Temperature of inner tube >And 5 ℃, judging that the odor-resistant closing condition is not met. That is, in the present embodiment, when Δ T1<1.5 ℃ and T Temperature of inner tube >And when the temperature is 5 ℃, judging that the peculiar smell preventing closing condition is not met, and continuously executing a peculiar smell preventing program by the air conditioner. Understandably, if Δ T1. Gtoreq.1.5 ℃ or T Temperature of inner tube And if the temperature is less than or equal to 5 ℃, judging that the odor-resistant closing condition is met, controlling the electromagnetic valve to be opened, and entering a preset conventional control program. It should be noted that in the present example, if Δ T1. Gtoreq.1.5 ℃ or T Temperature of inner tube The temperature of less than or equal to 5 ℃ is used as judgment to meet the odor-resistant closing condition, because when the delta T1 is more than or equal to 1.5 ℃, the indoor required cold quantity is more, the change of the evaporator can not meet the requirement, and the evaporator needs to return to the conventional control program of the air conditioner, namely the odor-resistant process needs to be quitted; when T is Temperature of inner tube When the temperature is less than or equal to 5 ℃, the hidden danger that the evaporator is frozen exists, the water hanging amount of the evaporator is enough, and the odor-preventing program can be quitted without preventing odor.
