Detailed Description
At present, the temperature of hot air blown out by an air conditioner is higher than the indoor temperature, the hot air can float upwards and cannot reach the ground, so that the ground temperature is low, and the heating effect is poor. In the existing air conditioner, the problem that hot air cannot fall to the ground cannot be fundamentally solved by changing the air outlet angle, and the hot air still cannot reach the ground under a low wind gear.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
[ first embodiment ] A method for manufacturing a semiconductor device
Based on the problem, the embodiment of the invention provides an air conditioner control method. Referring to fig. 1, which is a control flowchart of an air conditioning control method, the air conditioning control method includes the steps of:
step S1: in a heating mode, the indoor temperature T is acquired in real time1And indoor evaporator coil temperature T2；
The indoor temperature T is1The air conditioner; of course, the indoor temperature T1The temperature can be measured by a temperature sensor arranged at other indoor positions and is sent to the air conditioner.
Furthermore, the temperature of the indoor air outlet can be acquired at the air outlet of the air conditioner through a temperature sensor; of course, the indoor air outlet temperature can also be replaced by the temperature sensor measuring the temperature at the evaporator coil of the air conditioner. Wherein the indoor evaporator coil temperature T2And the temperature of the indoor air outlet has a good linear relation with the temperature of the indoor air outlet, and the temperature of the indoor air outlet can be equivalently adjusted by measuring and adjusting the temperature of an evaporator coil of the air conditioner.
Step S2: judging the indoor temperature T1And said indoor evaporator coil temperature T2Whether the difference value delta T meets the hot air non-landing condition or not and adjusting the frequency of the compressor.
The hot air non-landing condition is a condition that hot air cannot land stably under the condition, and Δ T ≧ TaThe difference Δ T ═ T1-T2。
Wherein, TaA forbidden ramp-up temperature difference preset for the air conditioner, the difference value Delta T being less than the forbidden ramp-up temperature difference TaWhen the air conditioner is used, the hot air can stably fall to the ground, and the air conditioner has a good heating effect on the bottom surface. That is, when the difference Δ T does not satisfy the hot air non-landing condition, that is, when the difference Δ T satisfies the hot air landing condition, the air conditioner may perform up-conversion on the compressor according to a conventional setting in a heating mode, so as to increase the temperature T of the indoor evaporator coil2So that the air conditioner achieves better heating effect.
Further, when the difference value delta T meets the hot air non-landing condition, the hot air landing effect is poor, the compressor is continuously kept to be subjected to frequency raising through the conventional setting of the air conditioner in the heating mode, the hot air cannot reach the ground, and the ground is cooled. Therefore, the frequency of the compressor is adjusted, and the frequency of the compressor is prohibited to rise, so that the current landing effect of the hot air is maintained or improved.
When the difference value DeltaT satisfies DeltaT < TaThe air conditioner can stably fall to the ground in the conventional setting in the heating mode, and has a good heating effect, so that the frequency of the compressor is controlled to recover the conventional control.
In a specific embodiment, referring to fig. 2, step S2 further includes, for example:
step S21: judging the indoor temperature T1And said indoor evaporator coil temperature T2Whether the difference value delta T meets the frequency reduction condition, namely delta T is more than or equal to TbIf this is true, the compressor frequency is decreased.
Wherein, TbA difference value delta T greater than or equal to the frequency reduction temperature difference T preset for the air conditioneraIn time, the hot air cannot fall to the ground stably, and the air conditioner does not have a good heating effect.
Further, when the difference Δ T satisfies the down-conversion condition, the compressor frequency decreases the operating frequency at a down-conversion rate of a (Hz/S) at a uniform speed, and after the compressor frequency decreases for T seconds, the compressor frequency decreases by at (Hz), and then the process returns to step S1, and the indoor temperature T is repeated1And said indoor evaporator coil temperature T2And (4) measuring and judging the hot air non-landing condition.
Preferably, the compressor frequency is slowly decreased at a decreasing rate of 6-10Hz/min, for example, 8Hz/min, when the system of the air conditioner can be stably operated.
Of course, the time measured by the temperature T1 and T2 and the time for determining the hot air non-landing condition are short, so the compressor down-conversion process can be continued, that is, the intermittent T second down-conversion step is not adopted, the compressor down-conversion process and the next step S1 are performed simultaneously until the difference Δ T does not satisfy the down-conversion condition, and the process proceeds to step S22.
Step S22: when the difference value delta T does not meet the frequency reduction condition, the indoor temperature T is judged1And said indoor evaporator coil temperature T2Whether the difference value Δ T of (1) satisfies the no-boosting condition, i.e., Tb＞ΔT≥TaIf this is true, the compressor frequency is no longer increased.
When the difference value delta T meets the frequency-rise forbidding condition, the compressor maintains the current heating frequency, the difference value delta T is guaranteed not to rise any more, and the hot air can keep a good landing effect. At the same time, returning to S1 for the indoor temperature T1And said indoor evaporator coil temperature T2And (4) measuring and judging the hot air non-landing condition.
Step S23: when the difference value delta T does not satisfy the frequency-increasing forbidding condition, namely delta T < TaAnd when the frequency of the compressor is increased, the frequency of the compressor is maintained in an increasing frequency state in a normal heating mode. Returning to S1 for the indoor temperature T while increasing the compressor frequency1And said indoor evaporator coil temperature T2And (4) measuring and judging the hot air non-landing condition.
In a specific embodiment, the air conditioner control method further includes, at step S0: according to the temperature difference T of the windshield to inhibit the frequency riseaAnd said temperature difference T of frequency reductionbAnd correcting, wherein the windshield at least comprises a high wind gear, a medium wind gear, a low wind gear and a mute gear.
Wherein, the lower the wind speed of the air conditioner, the worse the landing effect of the hot wind, and the temperature difference T for forbidding raising the frequency at the momentaAnd said temperature difference T of frequency reductionbNeed to be lowered so that the indoor evaporator coil temperature T2The adjustment by the air conditioning control method can be made earlier in the raising process.
With reference to fig. 2 and 3, the step S0 is located before the step S1 or after the step S2. For example, the step S0 is before the step S1, and the air conditioner control method returns to the step S1 after the determination and control process of the step S2, so that steps can be saved for the case that the windshield is not changed; after the step S0 is performed after the step S2, the air conditioner control method goes through the determination and control process of the step S2, and then goes through the step S0 and returns to the step S1, so that the windshield can be determined in real time for the condition of the change of the windshield.
Preferably, when the air conditioner is at the high wind gear and above, the frequency rise temperature difference T is forbiddenaAnd said temperature difference T of frequency reductionbAnd (4) not correcting.
When the air conditioner is in the middle wind gear, the temperature difference T for forbidding the frequency riseaAnd said temperature difference T of frequency reductionbAll correct down TxSaid T isxThe correction amount of (2) enables the hot air to fall to the ground under the middle windshield.
When the air conditioner is in the low wind gear, the temperature difference T for forbidding the frequency riseaAnd said temperature difference T of frequency reductionbAll correct down TySaid T isyThe correction amount of (2) enables the hot air to fall to the ground under the low wind level.
When the air conditioner is in the mute gear, the rise-frequency temperature difference T is forbiddenaAnd said temperature difference T of frequency reductionbAll correct down TzSaid T iszThe correction amount of (2) enables the hot air to fall to the ground under the mute gear.
Wherein the wind screen frequency correction amount under the high wind speed is smaller than the wind screen frequency correction amount under the low wind speed. Specifically, when the air conditioner is at or above the high wind level, the effect of falling to the ground at the same temperature is better than that under the high wind level, so that the rise-frequency-forbidden temperature difference T is achieved at the timeaAnd said temperature difference T of frequency reductionbThe frequency of the compressor is set to be a higher value, so that the air conditioner controls the frequency of the compressor to stop rising or start falling later, and the hot air can be regulated and controlled in time.
And when the windshield is low, the air speed of the air outlet of the air conditioner is low, and the temperature difference between the air outlet and the indoor space is large, so that the buoyancy of hot air is large, the landing effect of hot air is poorer, the frequency of the compressor needs to be controlled earlier to stop rising or start falling, and the hot air is controlled at lower temperature to obtain better landing effect.
Preferably, when the windshield is in the middle, low and quiet ranges, the corresponding correction amounts are adjusted, for example, in a gradient manner. For example, the unit adjustment is T0，Tx＝T0，Ty＝2T0，Tz＝3T0I.e. the forbidden rise temperature difference T in the medium wind range, the low wind range and the silence rangeaAnd said temperature difference T of frequency reductionbRespectively decrease T0、2T0、3T0。
Preferably, the rise-inhibiting temperature difference TaAnd said temperature difference T of frequency reductionbThe amount of reduction under the same type of the windshield varies. For example, when the air conditioner is in the middle wind gear, the rise-frequency temperature difference T is forbiddenaReduction of T01Said temperature difference of frequency reduction TbReduction of T02(ii) a When the air conditioner is in the low wind gear, the temperature difference T for forbidding the frequency riseaReduction of 2T01Said temperature difference of frequency reduction TbReduction of 2T02(ii) a When the air conditioner is in the mute position, the details are not repeated here.
