Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
Referring to fig. 1, fig. 1 is a schematic flow chart illustrating a method for adjusting a wind sweeping angle according to an embodiment of the present disclosure. The method for adjusting the wind sweeping angle is applied to an indoor unit of an air conditioner, and specifically comprises the following steps:
and S101, acquiring the temperature of a coil pipe, the condensation temperature, the return air temperature and the indoor environment temperature of the indoor unit running in the heating mode.
In practical application, temperature sensors are respectively arranged on a coil pipe, a condenser, a return air inlet of an indoor unit and a room blown by the indoor unit correspondingly, detection data of each temperature sensor are obtained in real time, and real-time acquisition of coil pipe temperature T1, condensing temperature Tc, return air temperature Tif and indoor environment temperature Tai of the indoor unit is achieved.
Further, the wind sweeping angle adjusting method further comprises the following steps:
step S102, respectively and correspondingly calculating the coil temperature variation, the condensation temperature variation, the return air temperature variation and the indoor environment temperature variation within a preset time interval according to the coil temperature, the condensation temperature, the return air temperature and the indoor environment temperature.
The preset time interval is the regulation period of the intelligent regulation wind sweeping angle of the indoor unit, and the temperature variation delta T1, the condensation temperature variation delta Tc, the return air temperature variation delta Tif and the indoor environment variation in the preset time interval are calculated every time the preset time interval passesAnd the temperature variation delta Tai is obtained by calculating the variation difference of the corresponding parameters in the preset time interval. For example, Δ T1n＝T1n-T1n-1，△T1nCharacterizing the amount of coil temperature change at the nth conditioning cycle, T1nIndicating the coil temperature, T1, taken at the nth conditioning cyclen-1Representing the coil temperature taken at the n-1 adjustment cycle.
Further, the wind sweeping angle adjusting method further comprises the following steps:
and step S103, judging the blowing state of the indoor unit according to the coil pipe temperature variation, the condensation temperature variation, the return air temperature variation and the indoor environment temperature variation.
And judging the blowing state of the indoor unit according to the coil pipe temperature variation delta T1, the condensation temperature variation delta Tc, the return air temperature variation delta Tif and the indoor environment temperature variation delta Tai which are obtained by calculation in the step S102 and serve as the current working condition information of the indoor unit, wherein the blowing state of the indoor unit comprises a normal state, a wind mixing state and a non-downblowing state.
The wind mixing state means that the wind sweeping angle of the indoor unit is too large, and blown hot wind directly reaches the vicinity of a return air inlet of the indoor unit, so that the blown hot wind is not blown far away to heat a room and is sucked back by the return air inlet, thereby forming the condition of direct circulation of air outlet and return air, and seriously influencing the heating effect of the indoor unit.
The non-downblow state means that the air sweeping angle of the indoor unit is too small, the indoor unit is used for blowing air upwards or straightly, and the indoor unit is not used for blowing air downwards, because the density of hot air is lower, the blown hot air is gathered at the top of a room, the indoor heating effect is poor, and a heat exchange cycle cannot be formed.
Therefore, the judgment of the air blowing state of the indoor unit is to judge whether the air sweeping angle of the indoor unit is reasonable.
Referring to fig. 2, fig. 2 is a schematic view illustrating a sub-step flow of step S103, wherein step S103 includes:
and step S1031, if the coil pipe temperature variation and the condensation temperature variation are positive values, the return air temperature variation is greater than half of the sum of the coil pipe temperature variation and the condensation temperature variation, and the ratio of the return air temperature variation to the indoor environment temperature variation is greater than a first preset value, the indoor unit is determined to be in a cross-wind state.
That is, when Δ T1 > 0, Δ Tc > 0, Δ Tif > (Δt1+ Δ Tc)/2, and Δ Tif/Δ Tai > Q1, it is determined that the indoor unit is currently in the cross-wind state.
In this embodiment, the value range of the first preset value Q1 is as follows: 2 < Q1 < 3, preferably Q1 < 2.
And a substep S1032 of determining that the indoor unit is not in a down-blowing state if the coil temperature variation and the condensation temperature variation are both positive values, the return air temperature variation is smaller than a half of a sum of the coil temperature variation and the condensation temperature variation delta Tc, and the return air temperature variation is larger than the indoor environment temperature variation.
That is, when Δ T1 > 0, Δ Tc > 0, Δ Tif < (Δ T1+ Δ Tc)/2, and Δ Tai < Δ Tif, it is determined that the indoor unit is currently in the non-downblow state.
It is understood that the sub-step S1031 and the sub-step S1032 do not have a sequential order in execution, and when the execution condition of the sub-step S1031 is satisfied, the sub-step S1031 is executed, and the sub-step S1032 is not executed; when the execution condition of sub-step S1032 is satisfied, sub-step S1032 is executed and sub-step S1031 is not executed.
With reference to fig. 1, the method for adjusting the wind sweeping angle may further include:
and step S104, controlling the wind sweeping angle of the indoor unit to reduce the first adjusting value under the condition that the indoor unit is judged to be in the wind mixing state.
And under the condition that the indoor unit is judged to be in a wind mixing state, namely the wind sweeping angle of the indoor unit is judged to be too large, and at the moment, the wind sweeping angle of the indoor unit is controlled to be reduced by a first adjusting value. In this embodiment, the first adjustment value is based on: q2 (return air temperature variation/indoor ambient temperature variation-1), calculated as:
α 1 — Q2 (Δ Tif/Δtai-1), where α 1 represents the first adjustment value and Q2 represents the minimum adjustment of the wind sweeping angle of the indoor unit.
The larger the delta Tif/delta Tai is, the more the rising speed of the return air temperature Tif is obviously faster than the rising speed of the indoor environment temperature Tai, which means that the larger the wind crossing degree is, the more the wind sweeping angle needs to be adjusted to be smaller.
Further, the wind sweeping angle adjusting method may further include:
and step S105, controlling the wind sweeping angle of the indoor unit to be increased by a second adjusting value under the condition that the indoor unit is judged to be in the non-downward blowing state.
And under the condition that the indoor unit is determined to be in the non-downward blowing state, namely the air sweeping angle of the indoor unit is determined to be too small, and at the moment, the air sweeping angle of the indoor unit is controlled to be increased by the second adjusting value. In this embodiment, the second adjustment value is based on: q2 return air temperature variation/indoor ambient temperature variation, calculated as:
a2 ═ Q2 Δ Tif/Δ Tai, and a2 characterizes the second adjustment value.
After the condition that hot air is not blown downwards is judged, the change of the wind sweeping angle is determined according to the ratio of delta Tif to delta Tai, namely the difference of the change trend. The slower the return air temperature Tif and the indoor environment temperature Tai rise, the larger the wind sweeping angle needs to be adjusted, so that more hot air is blown downwards.
