Embodiment (one)

Fig. 1 is the flow diagram according to anti-condensation air conditioning control method of the invention shown by embodiment (one).

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 includes mainly：

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

Optionally, the first operating parameter includes at least：First current frequency of compressor, the first indoor 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 supplied by air-conditioning, 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 to combine above-mentioned incidence relation, current running frequency is obtained, using as this flow 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 the Current Temperatures parameter detected by temperature sensor in step S101, and as the first indoor 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 the 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 Current Temperatures ginseng 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 judges that air-conditioning is existing or condensation will be generated； And when air-conditioning is unsatisfactory for the first anti-condensation condition, then judge that air-conditioning is not present or not will produce 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., it is of the invention whether existing or will to generate the condition judgment of condensation problem be simultaneously for air-conditioning Based on the comprehensive descision that the conditions such as compressor frequency, temperature, humidity and inner coil pipe temperature carry out, can improve 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 more 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 relatively low, 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 more 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 the 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 frequency of compressor this parameter being introduced the judgement to air-conditioning condensation problem is, works as air-conditioning Compressor when being run with the frequency more than refrigeration rated frequency, air-conditioning input indoor unit coolant quantity is big, refrigerant temperature is low, this The evaporation capacity that allows for indoor unit is big, internal temperature also decreases so that flows through steam in the room air of indoor unit more Add and is easy to condense into dew in machine indoors.Therefore, lower in the frequency of compressor, air-conditioning may be caused to generate solidifying Dew problem.

First damp condition, the first indoor humidity are more than the first humidity threshold；First humidity threshold is indoor for characterizing Humidity conditions, the larger humidity of the general value numerical value of the first indoor humidity, such as relative humidity 80%, relative humidity 90%, Etc.；Here, when humidity is more 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 relatively low.

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, in the case that humidity is larger indoors, sky may be caused 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 humidities 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 less 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 the dew condensation caused by the low temperature environment of inner coil pipe compared with It is few；

Optionally, the value of design factor A is 0.95, and the value of design factor B is 0.26, the calculating system of calculation constant C Number is 28.4.

The second operating parameter when S104, acquisition air-conditioning the first anti-condensation operation of execution, the second operating parameter includes following Parameter：Second indoor temperature, the second indoor humidity and the second inner coil pipe temperature；

In the present embodiment, the acquisition modes of the second operating parameter are referred to step S101 in step S104, herein not It repeats；

S105, it is based on the second operating parameter, determines whether air-conditioning meets exit criteria, exit criteria includes：

Here, when meeting the second inner coil pipe temperature condition, illustrate that the temperature regime of inner coil pipe at this time does not easily lead to dew It condenses on it, the condensation amount that air-conditioning generates is less.

S106, meet exit criteria in response to air-conditioning, control air-conditioning exits the first anti-condensation operation.

Here, air-conditioning exits after the first anti-condensation operation, can back switch to before executing the first anti-condensation operation Operating status continue to run with.

Optionally, for the air-conditioning products of frequency-converting type, the in step s 103 anti-condensation operation of first performed by air-conditioning Including：It controls the compressor of air-conditioning and carries out upconversion operation to set the period.By carrying out upconversion operation to compressor, make compressor Frequency be changed in the form of fluctuating, so as to further change input indoor unit refrigerant temperature, with to indoor unit Temperature carry out the adjustment of fluctuation, change and be easy to cause the temperature environment of dew condensation, and then reach and reduce dew condensation Purpose.

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

First stage, control compressor are downconverted to refrigeration rated frequency with the first frequency reducing rate 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, control compressor run the second duration with rated frequency of freezing；Here, air-conditioning is current to be less than first Before the refrigeration rated frequency of frequency is run, therefore the refrigerant temperature of input indoor unit will be less than 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, control compressor run third duration with the first upper limiting frequency.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 less than the first current operation frequency, therefore, in the practical heat-exchange performance of the air-conditioning of above-mentioned three phases Can cannot meet the needs of current working, therefore, control flow of the invention will be on frequency retrieval to first in the phase III Frequency is limited, and operation a period of time is maintained with the frequency in fourth stage, to meet the heat exchange demand of current working.

By to compressor progress upconversion operation, the frequency of compressor being made to be changed in the form of fluctuating, so as to The refrigerant temperature for further changing input indoor unit, to carry out the adjustment of fluctuation to the temperature of 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 of the current humiture to maintaining indoor environment.
