Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The air conditioner control method of the present invention will be described with reference to fig. 1. Fig. 1 is a schematic flow diagram of an air conditioner control method provided by the present invention, and as shown in fig. 1, an embodiment of the present invention provides an air conditioner control method, including:
step 110, responding to the air conditioner to start an anti-condensation mode, and acquiring current environmental parameters in real time; wherein the current environmental parameters include at least: indoor ambient temperature, indoor air outlet temperature, indoor humidity, outdoor ambient temperature and outdoor humidity.
It should be noted that, in this embodiment, the air conditioner includes components such as an indoor air outlet, an air conditioner compressor, and an air conditioner indoor unit.
Condensation is a phenomenon that when water vapor reaches a saturation degree in air, the water vapor condenses on objects with relatively low temperature, and the condensation is often found near air outlets of air conditioners, especially in positions where cold and hot air are easily crossed, such as air deflectors and air outlet frameworks, and if the condensation is serious, water drops drip from an internal machine, which causes user troubles.
The anti-condensation mode is a specific mode set by the embodiment for preventing condensation, in the anti-condensation mode, the air conditioner generates an anti-condensation control instruction according to the current environmental parameters and preset conditions, and the operation of an air conditioner compressor and an air conditioner indoor unit of the air conditioner is controlled through the anti-condensation control instruction, so that the temperature of an air outlet in the air conditioner is always kept above a critical point (namely a dew point) of water vapor condensation, and the generation of condensation is prevented.
The current environmental parameter obtained is a parameter related to water vapor condensation and may include: indoor ambient temperature, indoor air outlet temperature, outdoor ambient temperature, indoor humidity, outdoor humidity.
There are multiple ways to obtain the indoor environment temperature, and optionally, the indoor environment temperature is measured by a temperature sensor provided in the air conditioning system, or obtained by detection of other devices in a networking manner, or obtained by calculation of other data, which is not limited herein.
Similarly, there are various ways to obtain the indoor humidity, and optionally, the indoor humidity is measured by a humidity sensor of the air conditioning system itself, or the indoor humidity detected by other devices is obtained in a networking manner, or is obtained by other data calculation, which is not limited herein.
The temperature of the indoor air outlet can be obtained in various manners, and can be measured by a temperature sensor of the air conditioning system or obtained by calculating other data, which is not limited herein.
And step 120, determining the dew point temperature according to the indoor environment temperature, the indoor air outlet temperature and the indoor humidity.
Dew Point (dewpoint), often denoted by DT; since it is essentially a Temperature, the Dew Point is also called the Dew Point Temperature (Temperature of Dew Point), i.e. the Temperature at which the air is cooled to saturation while keeping the air pressure and water vapor constant. If the air temperature reaches the dew point temperature and the relative humidity reaches 100%, dew can be formed on the surface of the object by water vapor.
Dew point temperature is generally a direct observation, and if there is no relevant data, reference can also be made to ambient temperature, relative humidity, dew point look-up tables. FIG. 2 is a comparison table of ambient temperature, relative humidity, and dew point for the air conditioning control method provided by the present invention; and comparing the detected indoor environment temperature, indoor air outlet temperature and indoor humidity according to the figure 2 to obtain the dew point temperature. For example, when the indoor outlet temperature is detected to be 20 ℃ and the indoor humidity is detected to be 70%, the dew point temperature is 14.4 ℃ when the indoor humidity is checked to the table.
It should be noted that all temperatures detected allow an error in the range of ± 0.5 ℃ and humidity in the range of 10%, and integers are taken up nearby when compared to the data in the table. For example, if the temperature of the indoor air outlet is detected to be 23.4 ℃, the humidity in the table is 23 ℃, 53%, 55%, and the temperature of the indoor air outlet is detected to be 23.8 ℃, the humidity in the table is 24 ℃, 57%, and 60%. And 130, generating an anti-condensation control instruction based on the current environmental parameters and preset conditions, wherein the anti-condensation control instruction is used for adjusting the operating frequency of an air conditioner compressor and the air speed of an indoor unit of an air conditioner so as to enable the temperature of an air outlet of the air conditioner to be higher than the dew point temperature.
In the condensation prevention mode, the air conditioner generates a condensation prevention control instruction according to the current environmental parameters and preset conditions, the operation of an air conditioner compressor and an air conditioner indoor unit of the air conditioner is controlled through the condensation prevention control instruction, the temperature of an air outlet is increased, the temperature of the air outlet in the air conditioner is always kept above a dew point, and condensation is prevented.
Based on the above embodiment, in the method, generating the condensation prevention control instruction based on the current environmental parameter and the preset condition specifically includes:
calculating the difference between the indoor air outlet temperature and the dew point temperature to obtain a first temperature difference;
the preset conditions include: and generating an anti-condensation control instruction under the condition that the first temperature difference is larger than a first preset temperature difference, wherein the anti-condensation control instruction is used for controlling the air conditioner compressor to operate at the current frequency and controlling the indoor unit of the air conditioner to operate at the current wind speed.
Specifically, the dew point temperature is a temperature value, and when the water vapor in the air is saturated, the air temperature is the same as the dew point temperature; when the water vapor is not saturated, the air temperature is higher than the dew point temperature. The difference in dew point and air temperature may indicate the degree to which the moisture in the air is saturated from. The temperature drops below the dew point is a necessary condition for moisture condensation.
The difference between the air outlet temperature and the dew point temperature, namely the first temperature difference, can represent the degree of the water vapor distance saturation near the air outlet. The larger the first temperature difference is, the larger the degree of the water vapor near the air outlet from saturation is, the less the water vapor is condensed, and the less the condensation is generated; conversely, the smaller the first temperature difference is, the smaller the water vapor near the air outlet is from the saturation degree, and the more easily the water vapor is condensed, the more easily the condensation is generated.
From this, preset conditions have been established to this embodiment, through the judgement to difference size between air outlet temperature and the dew point temperature generate different condensation control command of preventing. The anti-condensation control instruction is used for controlling the frequency at which the air conditioner compressor operates and controlling the wind speed at which the air conditioner indoor unit operates.
The purpose of adjusting the operation frequency of the air conditioner compressor and the operation wind speed of the air conditioner indoor unit is to increase the first temperature difference for improving the temperature of the air outlet, namely, enlarge the saturated degree of the water vapor near the air outlet, so that the water vapor is not easy to condense, and further the condensation is prevented.
The first preset temperature difference is preset, and if the first temperature difference is larger than the first preset temperature difference, the water vapor near the air outlet is larger than the saturated degree, the water vapor is not easy to condense and is not easy to produce condensation, and under the condition, the air conditioner can operate at the frequency of the current air conditioner compressor and the wind speed of the current air conditioner indoor unit. And the generated anti-condensation control instruction indicates that the frequency of the air conditioner compressor and the air speed of the indoor unit of the air conditioner are unchanged.
The first preset time period is preset according to the parameters of the air conditioner and the environmental parameters.
Based on the above embodiment, in the method, generating the anti-condensation control instruction based on the current environmental parameter and the preset condition specifically includes:
calculating the difference between the indoor air outlet temperature and the dew point temperature to obtain a first temperature difference;
the preset conditions include: acquiring the duration of the current environmental parameter under the condition that the first temperature difference is less than or equal to a first preset temperature difference and greater than a second preset temperature difference;
and under the condition that the duration of the current environmental parameter reaches a second preset duration, generating the condensation prevention control instruction, wherein the condensation prevention control instruction is used for controlling the running frequency of the air conditioner compressor to be reduced by a first preset frequency value and controlling the air speed of the indoor unit of the air conditioner to be increased by a first preset air speed value.
Specifically, the first preset temperature difference and the second preset temperature difference are both preset, and the first preset temperature difference is larger than the second preset temperature difference.
If the first temperature difference is smaller than or equal to the first preset temperature difference and larger than the second preset temperature difference, the degree of water vapor near the air outlet is smaller than that of the previous embodiment, the water vapor is easier to condense than that of the previous embodiment, condensation is easier to generate than that of the previous embodiment, and under the condition that the duration time of the condition reaches the second preset time, the air supply amount of the air conditioner or the air supply temperature is increased.
If the indoor set amount of wind is less, then the temperature of air-out will reduce, will increase with the difference in temperature of indoor hot-air, and dew point temperature correspondingly reduces, changes and appears the condensation, consequently, the increase air output increases the operation wind speed of air conditioning indoor set promptly and can make the temperature of air-out suitably rise, reduces the difference in temperature with indoor hot-air, and dew point temperature correspondingly risees, is difficult for producing the condensation.
Similarly, the operation frequency of the air conditioner compressor is reduced by properly increasing the air supply temperature, so that the temperature of the outlet air can be properly increased, the temperature difference with the indoor hot air is reduced, the dew point temperature is correspondingly increased, and condensation is not easy to generate.
The purpose of improving the air supply temperature is to increase the first temperature difference, namely to enlarge the degree of the water vapor near the air outlet from the saturation, so that the water vapor is not easy to condense, and further the generation of condensation is prevented. And the generated condensation prevention control instruction indicates that the running frequency of the air conditioner compressor is reduced by a first preset frequency value and the wind speed of the indoor unit of the air conditioner is increased by a first preset wind speed value.
The second preset time, the first preset frequency value and the first preset wind speed value are all preset according to parameters of the air conditioner and environmental parameters.
Based on the above embodiment, in the method, generating the condensation prevention control instruction based on the current environmental parameter and the preset condition specifically includes:
calculating the difference between the indoor air outlet temperature and the dew point temperature to obtain a first temperature difference;
the preset conditions include: under the condition that the first temperature difference is smaller than or equal to a second preset temperature difference, acquiring the duration of the current environmental parameter;
and generating the condensation prevention control instruction under the condition that the duration of the current environmental parameter reaches a third preset duration, wherein the condensation prevention control instruction is used for controlling the running frequency of the air conditioner compressor to reduce a second preset frequency value and controlling the air speed of the indoor unit of the air conditioner to increase a second preset air speed value.
Specifically, the second preset temperature difference is preset, if the first temperature difference is smaller than or equal to the second preset temperature difference, the water vapor near the air outlet is less than the saturation degree, the water vapor is easier to condense compared with the previous embodiment, and the condensation is easier to generate compared with the previous embodiment.
If the indoor set amount of wind is less, then the temperature of air-out will reduce, will increase with the difference in temperature of indoor hot-air, and dew point temperature correspondingly reduces, changes and appears the condensation, consequently, the increase air output increases the operation wind speed of air conditioning indoor set promptly and can make the temperature of air-out suitably rise, reduces the difference in temperature with indoor hot-air, and dew point temperature correspondingly risees, is difficult for producing the condensation.
Similarly, the operation frequency of the air conditioner compressor is reduced by properly increasing the air supply temperature, so that the temperature of the outlet air can be properly increased, the temperature difference with the indoor hot air is reduced, the dew point temperature is correspondingly increased, and condensation is not easy to generate.
The purpose of improving the air supply temperature is to increase the first temperature difference, namely to enlarge the degree of the water vapor near the air outlet from the saturation, so that the water vapor is not easy to condense, and further the generation of condensation is prevented.
