Detailed Description
The present embodiment first provides a method for controlling condensation prevention of an air conditioner, and fig. 1 is a flowchart of a method for controlling condensation prevention of an air conditioner according to an embodiment of the present invention.
Referring to fig. 1, an anti-condensation control method of an air conditioner includes:
s102, detecting the indoor environment temperature, the indoor environment relative humidity and the heat exchanger coil temperature of an indoor unit of the air conditioner after detecting that the air conditioner is in a refrigeration mode;
when a user turns on the air conditioner, the air conditioner detects the working mode of the air conditioner in real time, the working mode of the air conditioner generally comprises a refrigeration mode, a heating mode, a dehumidification mode, a ventilation mode and the like, and when the air conditioner is in the heating mode or the ventilation mode, the air conditioner does not generate condensation; when the air conditioner is in a cooling mode or a dehumidifying mode, if the air conditioner is in an indoor space with higher humidity, the air conditioner is prone to condensation. The cooling mode in the present invention includes a cooling mode and a dehumidifying mode in a conventional sense. When the air conditioner is in the cooling mode, the risk of condensation phenomenon of the air conditioner is shown. The method comprises the steps of obtaining the indoor environment temperature, the indoor environment relative humidity and the heat exchanger coil temperature of an indoor unit of the air conditioner, and providing reference basis for judging the generation of condensation.
Humidity, a physical quantity representing the degree of dryness of the atmosphere. The less the water vapor contained in a certain volume of air at a certain temperature, the drier the air is; the more water vapor, the more humid the air.
Relative humidity, which represents the ratio of the absolute humidity in the air to the saturated absolute humidity at the same temperature, is a percentage. That is, the ratio of the mass of water vapor contained in a certain humid air to the mass of water vapor contained in saturated air at the same temperature is expressed by percentage.
The temperature of the heat exchanger coil refers to the temperature of the pipe wall of the heat exchanger coil of the indoor unit of the air conditioner, and specifically, a temperature sensor for detecting the temperature of the heat exchanger coil can be arranged on the heat exchanger coil.
S104, calculating the indoor environment dew point temperature of the indoor unit according to the indoor environment temperature and the indoor environment relative humidity;
the condensation problem of the air conditioner is always one of the technical problems in the development process of the air conditioner product, and the root cause of the condensation is that the evaporation temperature of a heat exchanger of an indoor unit of the air conditioner is lower than the air dew point temperature Td, so that water vapor in the air is precipitated into condensed water or dew when the water vapor passes through the heat exchanger of the indoor unit.
In the prior art, the calculation of the air dew point temperature is usually an extensive approximate estimation, and only the variable of the temperature is in a calculation formula, so that the difference between the calculated air dew point temperature and the actual air dew point temperature is large, and an accurate reference basis cannot be provided for the condensation prevention control of the air conditioner.
In this embodiment, the indoor environment dew point temperature and the indoor environment dew point temperature T at which the indoor unit is located are calculated by using the indoor environment temperature and the indoor environment relative humidity as variablesdThe calculation formula of (2) is as follows:
when the indoor ambient temperature T is greater than zero (water surface), the values of the two coefficients a and b may be "a" 7.5 and "b" 237.3, and when the indoor ambient temperature is less than or equal to zero (ice surface), the values of the two coefficients a and b may be "a" 9.5 and "b" 265.5. Due to the fact thatThe condensation phenomenon of the air conditioner occurs under the condition that the indoor environment temperature is higher in the refrigeration mode of the air conditioner, so the dew point temperature T of the indoor environment is calculated in the inventiondIn the above formula, the values of the two coefficients a and b may be a ═ 7.5 and b ═ 237.3.
The above-mentioned indoor environment dew point temperature TdThe calculation formula is a more practical and accurate calculation method, and the indoor environment dew point temperature T obtained by the formuladMore consistent with actual conditions to for the start-up of the control of air conditioner anti-condensation provide accurate reference condition, promote the accuracy nature of anti-condensation control.
S106, if the indoor environment temperature is greater than or equal to a preset threshold of the indoor environment temperature, the indoor environment relative humidity is greater than or equal to a preset threshold of the indoor environment relative humidity, and the temperature of a heat exchanger coil of the indoor unit is less than the indoor environment dew point temperature, starting an anti-condensation mode of the air conditioner, wherein the anti-condensation mode is a first anti-condensation mode or a second anti-condensation mode;
and the opening of the first anti-condensation mode and the opening of the second anti-condensation mode are determined according to the comparison result of the difference between the temperature of the coil pipe of the heat exchanger of the indoor unit and the dew point temperature of the indoor environment and the preset temperature difference.
The evaporating temperature of the heat exchanger of the indoor unit of the air conditioner can be controlled by the temperature T of the coil pipe of the heat exchanger of the indoor unit of the air conditionergAn approximate substitution is made, which can be done by comparing the heat exchanger coil temperature T of the indoor unitgAnd real-time indoor air dew point temperature TdThe size of (c) is controlled by taking anti-condensation measures into consideration.
Detecting the indoor environment temperature T and the preset threshold value T of the indoor environment temperaturelimitComparing the relative humidity f of the indoor environment with a preset threshold flimitComparing, if the indoor environment temperature T is greater than or equal to the preset threshold value T of the indoor environment temperaturelimitThe indoor environment relative humidity f is greater than or equal to the preset threshold f of the indoor environment relative humiditylimitE.g. TlimitMay be at 26 ℃ flimit70% when T is more than or equal to TlimitAnd f is more than or equal to flimitIt is indicated that there is a risk of condensation in the indoor environment at this time. Further adjusting the temperature T of the coil pipe of the heat exchanger of the indoor unitgDew point temperature T of indoor environmentdMaking a comparison if Tg<TdAnd then the temperature T of the coil pipe of the heat exchanger of the indoor unit of the air conditionergBelow air dew point temperature TdAt this time, the water vapor in the air is condensed out to form condensed water or dew upon cooling, so that the air conditioner should start the condensation prevention mode to prevent or reduce the generation of condensation when the above conditions are satisfied.
Moreover, for accurately controlling condensation, the condensation prevention mode can be a first condensation prevention mode or a second condensation prevention mode, and the temperature T of the coil pipe of the heat exchanger of the indoor unit is comparedgDew point temperature T of indoor environmentdIn time, the temperature T of the coil pipe of the heat exchanger of the indoor unit is required to be measuredgDew point temperature T of indoor environmentdDifference of (d) and a preset temperature difference Δ TlimitThe comparison result of the first and second anti-condensation modes determines whether to start the air conditioner so as to reasonably, flexibly and accurately control the condensation according to the severity of the condensation of the air conditioner. Wherein the preset temperature difference value Delta TlimitIs a value less than zero.
Specifically, if the temperature T of the coil of the heat exchanger of the indoor unit is higher than the temperature T of the coil of the heat exchanger of the indoor unitgSlightly lower than the dew point temperature T of the indoor environmentdThat is, the heat exchanger coil temperature T of the indoor unitgDew point temperature T of indoor environmentdIs greater than a preset temperature difference value delta TlimitI.e. Delta Tlimit＜Tg-Td< 0, wherein a temperature difference DeltaT is presetlimitAnd may be-5 c, which means that the condensation phenomenon of the air conditioner is not serious, and the first condensation prevention mode of the air conditioner is correspondingly turned on.
If the temperature T of the coil pipe of the heat exchanger of the indoor unitgIs seriously lower than the dew point temperature T of the indoor environmentdThat is, the heat exchanger coil temperature T of the indoor unitgDew point temperature T of indoor environmentdIs less than or equal to a preset temperature difference delta TlimitI.e. Tg-Td≤ΔTlimitWherein the difference of the preset temperature Δ TlimitAnd the temperature can be-5 ℃, which indicates that the condensation phenomenon of the air conditioner is serious, and the second condensation prevention mode of the air conditioner is correspondingly started.
Specifically, when the first anti-condensation mode of the air conditioner is started, the position of an air deflector of an air outlet of an indoor unit of the air conditioner is detected, if the air deflector is not located at the position of the maximum air output, the air deflector is adjusted to be located at the position of the maximum air output, after the air output of the indoor unit is increased, the heat exchange effect of a heat exchanger of the indoor unit and indoor air is increased, and therefore the temperature difference between the temperature of a coil pipe of the heat exchanger of the indoor unit and the indoor temperature is reduced, condensation of the air conditioner is not prone to occurring under the condition, or if condensation is generated, further aggravation of the condensation can be reduced under the condition. Meanwhile, the running frequency of a compressor of the air conditioner is reduced, so that the refrigerating capacity of the air conditioner is reduced, the difference between the temperature of a coil pipe of a heat exchanger of an indoor unit and the indoor temperature is reduced, the risk of condensation is further reduced, and the condensation is effectively controlled.
The frequency of the compressor can be adjusted to be at the current frequency F of the compressor0The frequency of the first calculated frequency Δ F is reduced, i.e., the adjusted frequency F of the compressor is equal to F0- Δ F. Wherein the calculation formula of the first calculation frequency Δ F is: Δ F ═ a × T + b × (T)d-Tg) + c; t is the indoor ambient temperature, TdIs the indoor ambient dew point temperature, TgThe temperature of the coil pipe of the heat exchanger of the indoor unit. a. b and c are three coefficients, a, b and c can be selected from the range of a being 0.01 to 0.05, b being 0.1 to 0.4 and c being 0.4 to 0.8, specifically, a, b and c can be selected from the range of a being 0.02, b being 0.1 and c being 0.6.
The purpose of controlling condensation is achieved when the frequency of the compressor is adjusted, and the problem that the comfortable feeling of a user is affected due to the fact that the difference between the front and the back of the indoor temperature is too large because the difference between the front and the back of the frequency of the compressor is too large is avoided. Therefore, the embodiment adopts the above calculation formula to obtain the reduction value of the compressor frequency, and controls the amplitude of the compressor frequency adjustment by reasonably setting the coefficients a, b and c, the compressor frequency is adjusted no more than 5HZ each time, and the optimal frequency adjustment range can be controlled within 0.5HZ to 3 HZ. When the condensation is controlled, the frequency of the compressor is reduced, and the phenomenon that a human body feels uncomfortable suddenly is avoided, so that the user experience degree and the comfort level are improved. And on the premise of preventing condensation and ensuring the refrigerating capacity, the frequency of a compressor of the air conditioner is reduced, and the energy conservation and environmental protection of the air conditioner are improved.
When the second anti-condensation mode of the air conditioner is started, the temperature T of the coil pipe of the heat exchanger of the indoor unit is higher than the first temperature TgIs already seriously lower than the dew point temperature T of the indoor environmentdThe adjusting force of the air conditioner needs to be increased, the position of an air deflector of an air outlet of an indoor unit of the air conditioner can be detected, and if the air deflector is not located at the position of the maximum air output, the position of the air deflector located at the maximum air output is adjusted, so that the temperature difference between the temperature of a coil pipe of a heat exchanger of the indoor unit and the indoor temperature is reduced, and condensation is prevented. At the same time, the running frequency of the compressor of the air conditioner is reduced, and the frequency of the compressor is adjusted to be at the current frequency F of the compressor1The first calculation frequency delta F is reduced on the basis, so that the refrigerating capacity of the air conditioner is reduced, and the difference between the temperature of a coil pipe of a heat exchanger of the indoor unit and the indoor temperature is reduced. And further adjusting the rotating speed of the indoor unit fan, adjusting the rotating speed of the indoor unit fan to increase the first calculated rotating speed on the basis of the current rotating speed of the indoor unit fan, and increasing the rotating speed of the fan, so that the air outlet temperature at the air deflector is increased, and the problem of condensation and water dripping near an air outlet of the air conditioner is avoided.
Wherein the adjusted frequency F of the compressor is equal to F0- Δ F. Wherein the calculation formula of the first calculation frequency Δ F is: Δ F ═ a × T + b × (T)d-Tg) + c; t is the indoor ambient temperature, TdThe dew point temperature of indoor environment is shown, and Tg is the temperature of a coil pipe of a heat exchanger of the indoor unit. The calculation result of Δ F may retain one decimal, a, b, and c are three coefficients, and a, b, and c may range from 0.01 to 0.05, 0.1 to 0.4, and 0.4 to 0.8, specifically, a, b, and c may be selected from 0.02, 0.1, and 0.6.
Wherein the adjusted rotating speed N of the indoor unit fan is N0+ Δ N, where Δ N is calculated as: Δ N ═ int (mx (T)d-Tg) + n); wherein int is an integer taking function, TdIs the indoor ambient dew point temperature, TgThe temperature of the coil pipe of the heat exchanger of the indoor unit. m and n are two coefficients, the value range of m and n can be m is 3.5-5.0, n is 10-40, concretely, the value of m and n can be selected from m is 4.0, and n is 30.
When increasing indoor set fan rotational speed, need avoid fan rotational speed adjustment range too big, arouse user's attention, influence user's use and experience. Therefore, the increase of the fan of the indoor unit is obtained by adopting the calculation formula, the rotation speed of the fan is slowly adjusted by reasonably setting the coefficients m and n and controlling the adjustment range of the rotation speed of the fan within a certain range, such as within 100rpm, so that the air outlet temperature of the air outlet of the indoor unit is increased, the generation of condensation is prevented, meanwhile, the interference on the rest of a user is avoided, and the use experience and the comfort level of the user are improved.
The air conditioner is started to be in a condensation prevention mode, the air conditioner can detect the indoor environment temperature, the indoor environment relative humidity and the heat exchanger coil temperature of the indoor unit at intervals of a certain time, the indoor environment dew point temperature is calculated according to the indoor environment temperature and the indoor environment relative humidity, whether the air conditioner at the current moment meets the first condensation prevention mode or the second condensation prevention mode is judged, if yes, the adjustment of the first condensation prevention mode of the air conditioner or the adjustment of the second condensation prevention mode of the air conditioner is repeated, and the air conditioner is adjusted to be in a state that condensation cannot be generated.
When the air conditioner detects that the indoor environment temperature T is less than the preset threshold T of the indoor environment temperaturelimitE.g. TlimitMay be 26 ℃ when T<TlimitAt this time, it is described that the indoor ambient temperature is not very high, and the difference between the indoor ambient temperature and the temperature of the heat exchanger coil of the indoor unit is relatively small, and in this case, the possibility of generating condensation is very small, so the condensation prevention mode of the air conditioner can be ended at this time, and the state of the air conditioner is adjusted to the initial mode before the condensation prevention mode, for example, if the air conditioner is in the first condensation prevention mode at this time, the position of the wind shield is adjusted to the position before the first condensation prevention mode from the position at the maximum air output at this time, and the frequency of the compressor of the air conditioner is adjusted to the position before the frequency reduction from the current low-frequency operation stateThe original frequency. Similarly, if the air conditioner is in the second anti-condensation mode, the damper air, the compressor frequency of the air conditioner and the fan speed of the indoor unit need to be adjusted to the previous states.
When the relative humidity f of the indoor environment is smaller than the preset threshold f of the relative humidity f of the indoor environmentlimitE.g. flimitAt 70%, when f<flimitAt this time, since it is described that the relative humidity of the indoor environment is not so high and the air conditioner is not likely to generate condensation in such an indoor environment, the condensation prevention mode of the air conditioner may be ended and the state of the air conditioner may be adjusted to the state before the condensation prevention mode.
When the temperature T of the coil pipe of the heat exchanger of the indoor unitgGreater than or equal to the dew point temperature T of the indoor environmentdI.e. if Tg≥TdIn this case, since the air conditioner does not generate condensation even under such a condition, the condensation prevention mode of the air conditioner may be terminated and the state of the air conditioner may be adjusted to a state before the condensation prevention mode.
