Detailed Description
At present, an outdoor unit of an air conditioner is usually installed in a grille for beauty, but the heat exchange efficiency of the outdoor unit is reduced, and the temperature is increased. The invention controls the rotating speed of the outdoor fan by detecting the environment temperature of the outdoor unit and the temperature of the outer pipe of the outdoor condenser, thereby solving the problem of poor heat dissipation of the outdoor unit.
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. 1-2, the air conditioner control method includes, for example:
step S1: turning on a cooling mode or a dehumidifying mode of the air conditioner 200;
step S2: detecting the environment temperature of an outdoor unit and the temperature of an outer pipe of an outdoor condenser, and judging whether the environment temperature of the outdoor unit and the temperature of the outer pipe of the outdoor condenser meet the regulation condition of an outdoor fan;
step S3: if so, the speed of the outdoor fan 212 is adjusted.
In step S1, when the air conditioner 200 is in the cooling mode or the dehumidification mode, the heat of the indoor air is transferred to the outdoor space by the refrigerant, and is transferred to the outdoor air by the heat exchange function of the condenser and the heat dissipation function of the outdoor fan 212. However, after the outdoor unit 210 is installed in the grille, the hot air cannot circulate out of the grille in time, which causes the ambient temperature of the outdoor unit to increase, the temperature of the outer tube of the condenser to increase, the cooling effect of the air conditioner 200 to decrease, and the power consumption to increase. Therefore, the poor heat dissipation of the outdoor unit 210 can be more accurately reflected by detecting the ambient temperature of the outdoor unit and the temperature of the outer tube of the outdoor condenser.
In a specific embodiment, in step S2, the detecting the outdoor unit ambient temperature and the outdoor condenser outer tube temperature includes, for example: detect first outer quick-witted ambient temperature T when compressor 211 opens1(ii) a Compressor 211 is turned on t1After the time, detecting the ambient temperature T of the second external machine2。
Further, the first outdoor unit ambient temperature T1And the second external machine ambient temperature T2Measured by an outer ring temperature sensor. WhereinThe outer ring temperature sensors can be arranged in one group or multiple groups. Correspondingly, the first outer unit ambient temperature T1The measured value of any one of the outer ring temperature sensors or the average value or the maximum value of a plurality of outer ring temperature sensors when the compressor 211 is started; the second outdoor unit ambient temperature T2Is the compressor 211 is turned on t1After a time, the measured value of any one of the outer ring temperature sensors or the average or the maximum of the measured values of the outer ring temperature sensors of the plurality of outer rings.
Still further, t1Is in the range of 120s to 300s, for example 160 s. Within the value range, the environment temperature T of the second external machine2Will not be too small, resulting in natural variation of outdoor ambient temperature to the second outdoor unit ambient temperature T2The measured value of (a), the ambient temperature T of the second external machine2A large error is generated; the second outdoor unit ambient temperature T2The outdoor unit 210 is not excessively large, and thus may be in a high temperature state for a long time to malfunction.
Preferably, the outdoor fan adjusting conditions include, for example: a first outdoor fan regulation condition, the first outdoor fan regulation condition comprising: judging the environment temperature variation delta T of the outdoor unitwh＝T2-T1Whether or not to satisfy DeltaTwh＞Ta(ii) a Wherein, TaThe threshold value of the variation of the environment temperature of the outdoor unit is set.
For example, at t1On the basis of 160s, TaThe range of values of (A) is 6 to 10 ℃, e.g., 7 ℃, 8 ℃, 9 ℃, and is not limited herein.
Preferably, in step S2, the detecting the outdoor unit ambient temperature and the outdoor condenser outer tube temperature further includes: compressor 211 is turned on t2After time, t is detected2Time condenser outer tube temperature Twg。
Further, the condenser outer tube temperature TwgMeasured by a condenser outer tube temperature sensor. Wherein, the condenser outer tube temperature sensor also can be provided with one or more groups. Accordingly, the compressor 211 is turned on t2After time, coolTemperature T of external tube of condenserwgThe measured value of (b) may be a measured value of any one of the condenser outer tube temperature sensors, or may be an average value or a maximum value of measured values of a plurality of condenser outer tube temperature sensors.
Still further, t2Is in the range of 120s to 300s, for example 160 s. Within the value range, the temperature T of the outer pipe of the condenserwgCan not be too small, resulting in error to the temperature T of the outer pipe of the condenserwgThe influence is large; the temperature T of the outer pipe of the condenserwgIt is not too large, so that the outdoor unit 210 is in a high temperature state for a long time, and the condenser is out of order.
Preferably, t is1And t2Taking the same value, for example, both values are 160s, that is, after the compressor 211 is started for 160s, the ambient temperature variation Δ T of the external unit is measured and judged simultaneouslywhAnd the condenser outer tube temperature Twg。
Preferably, the outdoor fan adjusting conditions further include, for example: a second outdoor fan adjustment condition, the second outdoor fan adjustment condition comprising: judging the temperature T of the outer tube of the condenserwgWhether or not T is satisfiedwg＞Tb(ii) a Wherein, TbIs the condenser outer tube temperature threshold.
Correspondingly, the first outdoor fan adjustment condition and the second outdoor fan adjustment condition are determined at the same time, and when both the first outdoor fan adjustment condition and the second outdoor fan adjustment condition are satisfied, the outdoor unit 210 is indicated to have poor heat dissipation.
Preferably, the air conditioning control method further includes, for example: judging the temperature T of the outer tube of the condenserwgWhether the outdoor fan regulation prohibition condition is met or not, and if the outdoor fan regulation prohibition condition is met, the outdoor fan 212 normally operates; wherein the outdoor fan regulation forbidding condition is Twg＜TcThe priority of the outdoor fan regulation prohibition condition is higher than that of the outdoor fan regulation condition, TcA threshold value for prohibiting adjustment of the outdoor fan. I.e. the compressor 211 is on t2After the time, the condenser outer tube temperature T is measuredwgFirstly, judging whether the temperature T of the outer tube of the condenser iswgWhen the outdoor fan is too large, the regulation forbidding condition is Twg＜TcWhen the first outdoor fan adjusting condition is met, the outdoor temperature is low, the working condition is good, and even if the first outdoor fan adjusting condition is met, the outdoor unit 210 has poor heat dissipation, the outdoor fan 212 does not need to be adjusted; when the outdoor fan forbids to adjust the condition is Twg＜TcAnd when the second outdoor fan is not satisfied, judging the regulation condition of the second outdoor fan.
In a specific embodiment, in step S3, the adjusting the rotation speed of the outdoor fan 212 includes, for example: increasing r of current outdoor fan rotating speed r0(ii) a Wherein r is0The rotating speed increment of the outdoor fan is preset. For example, r0Is in the range of 50 to 150RPM, for example 100 RPM. Within this range, the heat dissipation effect of the outdoor unit 210 can be effectively improved, and excessive adjustment can be avoided, which leads to excessive noise or excessive heating of the motor.
