As shown in Figure 1, the present invention provides a kind of anti-condensation air conditioning control methods；Specifically, the stream of the control method Journey step mainly includes：

S101, the first operating parameter for obtaining air-conditioning；

Optionally, the first operating parameter includes at least：First current frequency of compressor, the first room temperature, the first Room Interior humidity and the first inner coil pipe temperature；

In the present embodiment, the first operating parameter can detect to obtain by the sensor of multiple and different types, or by sky The operation data of itself is adjusted directly or indirectly to obtain；

For example, the compressor of air-conditioning is the electrical energy drive running by air-conditioning supply, the actual motion frequency of compressor is main Influenced by its current operating voltage and/or operating current, i.e., the operating voltage of this parameter of compressor frequency and compressor and/ Or therefore operating current, passes through the currently running operating voltage of acquisition compressor and/or operating current at certain incidence relation Etc. operation datas, so that it may further combine above-mentioned incidence relation, obtain current running frequency, using as this process First current frequency；

The indoor unit of air-conditioning is configured with a temperature sensor, and temperature sensor can be used for detecting the Current Temperatures of indoor environment Parameter can obtain Current Temperatures parameter detected by temperature sensor in step S101, and as the first room temperature；

Similarly, the indoor unit of air-conditioning is configured with a humidity sensor, and humidity sensor can be used for detecting working as indoor environment Preceding humidity parameter can obtain current humidity parameter detected by humidity sensor in step S101, and as the first interior Humidity；

Similar, the indoor unit of air-conditioning is configured with another temperature sensor also at inner coil pipe, and the temperature sensor is available The ginseng of Current Temperatures detected by the temperature sensor can be obtained in the Current Temperatures parameter of detection inner coil pipe, step S101 Number, and as the first inner coil pipe temperature；

S102, it is based on the first operating parameter, determines whether air-conditioning meets the first anti-condensation condition；

In the present embodiment, the first anti-condensation condition for can be used under air-conditioning current operating conditions whether it is existing or Condensation problem will be generated；When air-conditioning meets the first anti-condensation condition, then determines that air-conditioning is existing or condensation will be generated； And when air-conditioning is unsatisfactory for the first anti-condensation condition, then determine that air-conditioning is not present or will not generate condensation, in this way, being based on first Operating parameter and judgement to the first anti-condensation condition, can further determine the subsequent operation of air-conditioning；

In the present embodiment, the first anti-condensation condition is including at least in first frequency condition, the first damp condition and first Coil temperature condition, i.e., condition judgement that is of the invention whether existing for air-conditioning or will generating condensation problem is simultaneously Based on the comprehensive descision that the conditions such as compressor frequency, temperature, humidity and inner coil pipe temperature carry out, can be improved solidifying for air-conditioning The judgement accuracy of dew problem is avoided because of the extremely generated erroneous judgement problem of individual parameters；

Specifically, first frequency condition, the first current frequency is greater than refrigeration rated frequency；Here, for existing type Air-conditioning products, air-conditioning are usually run according to rated frequency, but in some cases, for the need of the practical heat exchange amount of air-conditioning It asks, it is if cryogenic temperature set by user in the case of refrigeration is lower, the larger bad working environments of indoor/outdoor temperature-difference, then lower in order to meet Cryogenic temperature needed for heat exchange amount, then compressor will appear overclocking operation working condition, at this point, air-conditioning actual motion frequency Rate is greater than refrigeration rated frequency；It should be understood that since condensation problem typically occurs in the sky run under summer hot climate It adjusts in product, therefore, in the present embodiment only using refrigeration rated frequency corresponding to refrigeration mode as judging the of compressor The reference threshold of the numerical values recited of one current frequency；

Here, the advantages of this parameter of the frequency of compressor being introduced the judgement to air-conditioning condensation problem is, works as air-conditioning Frequency operation of the compressor to be greater than refrigeration rated frequency when, air-conditioning input indoor unit coolant quantity is big, refrigerant temperature is low, this The evaporation capacity for allowing for indoor unit is big, internal temperature also decreases, and passes through steam in the room air of indoor unit more Add and is easy to condense into dew in machine indoors.Therefore, in the lower situation of the frequency of compressor, it may cause air-conditioning and generate and coagulate Dew problem.

First damp condition, the first indoor humidity are greater than the first humidity threshold；First humidity threshold is indoor for characterizing Humidity conditions, the general biggish humidity of value numerical value of the first indoor humidity, such as relative humidity 80%, relative humidity 90%, Etc.；Here, when humidity is greater than the first humidity threshold indoors, then illustrate that the indoor humidity in current indoor environment is larger, water Vapour content is more；When humidity is not more than the first humidity threshold indoors, then illustrate that the indoor humidity in current indoor environment is smaller, Moisture content is lower.

Here, indoor humidity is bigger, then the moisture being blended in room air is also more, and air flows through air conditioning chamber indoors When interior machine, then the steam for being easy to condense into dew is also more；Therefore, it may cause sky in the biggish situation of humidity indoors It adjusts and generates condensation problem.

Inner coil pipe temperature is lower, then steam flows through that the dew condensed when indoor unit is more, then above-mentioned " A* first is indoor The first indoor humidity of temperature+B*-C " is used to characterize the temperature limit that inner coil pipe is easy condensation dew, in current inner coil pipe temperature When lower than the temperature limit, the low temperature environment of inner coil pipe is easy to flow through the condensation vapor in its room air into dew；? Current inner coil pipe temperature be not less than the temperature limit when, then the amount of dew condensation caused by the low temperature environment of inner coil pipe compared with It is few；

Specifically, the compressor of control air-conditioning includes in the upconversion operation that each setting period carries out：

First stage controls compressor with the first frequency reducing rate and is downconverted to refrigeration rated frequency from the first upper limiting frequency；This In, the first upper limiting frequency is to achieve the purpose that the anti-condensation default frequency values of air-conditioning frequency conversion, which is between the The numerical value or the first upper limiting frequency of one current frequency and refrigeration rated frequency are set as the first current frequency；

Second stage controls compressor with rated frequency of freezing and runs the second duration；Here, air-conditioning is with current lower than first The refrigeration rated frequency of frequency is run, therefore the refrigerant temperature of input indoor unit will be lower than before upconversion operation in the second duration Refrigerant temperature；So that the actual temperature in indoor unit increases, condensation amount is reduced；It is same reduce condensation effect in the first stage and Also there is similar effect in phase III.

Fourth stage controls compressor with the first upper limiting frequency and runs third duration.Here, the compressor of air-conditioning is with first Current frequency operation is mainly to meet the needs of current working；Due in the first stage, the sky of second stage and phase III The actual motion frequency of tune is lower than the first current operation frequency, therefore, in the practical heat-exchange performance of the air-conditioning of above-mentioned three phases It can be the demand for not being able to satisfy current working, therefore, control flow of the invention will be on frequency retrieval to first in the phase III Frequency limit rate, and operation a period of time is maintained with the frequency in fourth stage, to meet the heat exchange demand of current working.

By carrying out upconversion operation to compressor, the form for fluctuating the frequency of compressor is changed, so as to The refrigerant temperature of input indoor unit is further changed, the adjustment of fluctuation is carried out with the temperature to indoor unit, change is be easy to cause The temperature environment of dew condensation, and then achieve the purpose that reduce dew condensation；Pass through, the frequency conversion change because of compressor can also be reduced Change the adverse effect to the current temperature and humidity for maintaining indoor environment.
