Embodiment (one)

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

As shown in Figure 1, the present invention provides a kind of control method that air-conditioning is anti-condensation, can be used for according to space residing for air-conditioning Environmental parameter, the operational mode of air-conditioning is adjusted, run fresh air pattern introduce indoor fresh air by way of reduce sky The condensation amount of tune；Specifically, the process step of the control method includes mainly：

S101, the first indoor humidity value for obtaining space residing for air-conditioning；

In the present embodiment, the indoor unit of air-conditioning is configured with a humidity sensor, and humidity sensor can be used for sensing chamber's inner ring The current humidity parameter in border can obtain the current humidity parameter detected by humidity sensor in step S101, and as One indoor humidity value.

Alternatively, may be configured with an independent humidity sensor in the indoor environment of user or similar to Humidity Detection work( The device of energy, the humidity sensor are used to detect the current humidity parameter of indoor environment, air-conditioning of the present invention and the humidity sensor By home LAN into row data communication, to can also obtain the current wet of indoor environment above-mentioned from the humidity sensor Spend parameter.

S102, the first outside humidity value for obtaining space residing for air-conditioning；

In the present embodiment, the outdoor unit of air-conditioning is configured with another humidity sensor, which can be used for sensing chamber The current humidity parameter of external environment can obtain this in step S102 and be set to working as detected by the humidity sensor of outdoor unit Preceding humidity parameter, and as the first outside humidity value.

Alternatively, air-conditioning of the present invention accesses external network by home LAN, and can be from air-conditioning products service provider Server, or the network platform of weather data information is provided, the outdoor environment data corresponding to the coordinate position of the air-conditioning are searched, Outdoor environment data include the current humidity parameter of outdoor environment, in this way, step S102 can be through searching obtained outdoor environment Current humidity parameter as the first outside humidity value.

S103, judge whether the first indoor humidity value is more than preset condensation humidity threshold, if so, thening follow the steps S104；If it is not, then flow terminates；

Air-conditioning of the present invention prestores one or more condensation humidity thresholds, and condensation humidity threshold has with current indoor temperature There are mapping relations, such as when current indoor temperature is 20 DEG C, the condensation humidity threshold of mapping is relative humidity 80%；Current When indoor temperature is 25 DEG C, the condensation humidity threshold of mapping is relative humidity 75%, etc.；The mapping relations indicate current room Under interior temperature condition, air-conditioning not condensation or the less corresponding indoor humidity condition of condensation, when the current humidity of indoor environment When without departing from the condensation humidity threshold, then condensation or condensation be not less for air-conditioning, when the current humidity of indoor environment is solidifying beyond this When revealing humidity threshold, air-conditioning will appear condensation problem；For example, when current indoor temperature is 20 DEG C, if indoor environment is worked as When preceding humidity is 70%, condensation or condensation be not less substantially for air-conditioning, and if when the current humidity of indoor environment is 85%, it is empty Tune then tends to condensation problem occur.

Optionally, what air-conditioning prestored is not limited to single humidity, or one or more humidity range values, Each humidity range value corresponds to a temperature value or temperature range value.

Before the judgment step for carrying out step S103, generally requires first detection and obtains the current temperature value of indoor environment, Later, according to the mapping relations to prestore, the condensation humidity threshold corresponding to the current temperature value is determined.

In this way, the size by judging the first indoor humidity value and condensation humidity threshold, it may be determined that indoor unit is current Indoor humidity under the conditions of whether be susceptible to condensation problem.

S104, judge whether the first outside humidity value is less than preset outside humidity threshold value, if so, thening follow the steps S105；If it is not, then flow terminates；

Air-conditioning of the present invention prestores one or more outside humidity threshold values, in general, outside humidity threshold value is less than above-mentioned Condensation humidity threshold, and be mostly to indicate that the lower humidity of outdoor moisture content is relatively low, such as relative humidity 50%, relative humidity 60%, etc..

Therefore, when the first outside humidity value is less than outside humidity threshold value, then in the air for illustrating current outdoor environment Moisture content is relatively low.

S105, control operation of air conditioner fresh air pattern.

In this way, the moisture content for meeting indoor environment in step s 103 is easy to cause indoor unit condensation, and step S104 In the case of the moisture content of middle outdoor environment is lower, operation of air conditioner fresh air pattern above-mentioned of the present invention, by water in outdoor environment Relatively low, the more dry outdoor air of vapour content is introduced into indoor environment, and higher, more wet with moisture content in indoor environment The room air of profit mixes, and the moisture content in the room air after mixing is reduced in a manner of similar " neutralization ", makes sky The humidity value of indoor environment is reduced to condensation humidity value even lower after allocation and transportation row fresh air pattern, to reduce air conditioner indoor unit Condensation amount prevents " blowing water " phenomenon, promotes the usage experience of user.

In an embodiment of the present invention, the condensation amount on the heat exchanger of indoor unit is not only by the current humidity shadow of indoor environment It rings, is influenced also depending on the temperature for flowing through its refrigerant；The refrigerant temperature for flowing through heat exchanger is lower, then solidifying on heat exchanger Dew amount is more, and the refrigerant temperature for flowing through heat exchanger is higher, then the condensation amount on heat exchanger is fewer, in this way, being flowed through by adjusting The refrigerant temperature of heat exchanger can also achieve the purpose that change air-conditioning condensation amount.

The running frequency control of the main compressed machine of the refrigerant temperature of air-conditioning, the running frequency of compressor is high, then it is exported The heat that is contained of refrigerant it is more, refrigerant temperature is higher；The running frequency of compressor is low, then the heat that the refrigerant of its output is contained Amount is few, and refrigerant temperature is relatively low, in this way, being controlled by the running frequency to compressor, can adjust and flow through the cold of heat exchanger Matchmaker's temperature further realizes the control effect to air-conditioning condensation amount.

Specifically, control method of the present invention further includes：

Obtain initial indoor humidity value when operation of air conditioner refrigeration mode；In the present embodiment, condensation problem generally occurs In the summer of high temperature and humidity, at this point, air-conditioning is mostly run in a chiller mode, the present invention is the initial interior detected under refrigeration mode Humidity value；Here, the fresh air pattern in air-conditioning not yet operating procedure 105；

In embodiment, the detection mode of initial indoor humidity value is referred to step S101, and therefore not to repeat here.

Initial indoor humidity value is compared with condensation humidity threshold；

When initial indoor humidity value is more than condensation humidity threshold, controls and level-one frequency reducing is carried out to the compressor of air-conditioning；This In, the running frequency of compressor when level-one frequency reducing is based on operation of air conditioner refrigeration mode reduces pressure according to the first ratio of setting The running frequency of contracting machine.

Such as the first ratio 80% of setting, the running frequency of compressor is 1200Hz when operation of air conditioner refrigeration mode, then one The running frequency of compressor after grade frequency reducing is 1200*80%=960Hz.

In this way, before air-conditioning judges whether to run fresh air pattern according to indoor and outdoor humidity parameter, initial room can be passed through Interior humidity value adjusts the running frequency of compressor with the comparison result of threshold value in condensation room, is adjusted with the condensation amount to air-conditioning Section.The advantages of this control mode, is, can be disturbed to the temperature of room air to avoid the introduced outdoor air of fresh air pattern It is dynamic to influence, ensure the stationarity of indoor environment temperature.

In embodiment, what is obtained in step S101 is sky after compressor sets duration with level-one frequency reducing operation first Adjust the first indoor humidity value in residing space.In this way, the case where failing to solve air-conditioning condensation can be adjusted in the frequency of compressor Under, the air humidity content of indoor environment is adjusted by the control flow of step S101 to S105, by indoor environment Humidity is reduced to the humidity conditions of air-conditioning not condensation or few condensation.

Preferably, 10~15 minutes a length of when the first setting.

In an embodiment of the present invention, of the invention to improve the accuracy that air-conditioning controls indoor humidity under fresh air pattern Control method further includes：

After obtaining operation of air conditioner fresh air pattern the second setting duration, humidity value in the second Room in space residing for air-conditioning； In the present embodiment, for the detection mode of humidity value with reference to step S101, the second setting duration is preferably 10~15 minutes in second Room；

When humidity value is more than condensation humidity threshold in second Room, controls and two level operation frequency is carried out to the compressor of air-conditioning Rate.Here, two level frequency reducing is the running frequency of the compressor based on air-conditioning after aforementioned level-one frequency reducing, according to the second of setting Ratio reduces the running frequency of compressor.

Such as the second ratio also 80% of setting, the running frequency for the compressor that air-conditioning obtains after level-one frequency reducing is 960Hz, then the running frequency of the compressor after two level frequency reducing is 960*80%=768Hz.

In this way, reducing the running frequency of compressor again under fresh air pattern, dry outdoor fresh air and compressor will be introduced Two kinds of control modes of frequency reducing are combined, and in the case where reducing room air water capacity, further decrease the heat exchanger of indoor unit Surface temperature so that indoor unit can not condensation or few condensation.

Preferably, when humidity value is more than condensation humidity threshold in second Room, can not only two level drop be carried out to compressor Frequency operates, at the same time it can also control the wind-speed gear for improving fresh air pattern, as in step S105 when operation of air conditioner fresh air pattern Initial wind-speed gear is that apoplexy wind shelves can be by the fresh air of air-conditioning then when humidity value is more than condensation humidity threshold in second Room Pattern improves supreme wind wind shelves by apoplexy wind shelves, and the rate of outdoor air is conveyed to improve air-conditioning to indoor environment, accelerates to reduce The humidity of room air.

In the present embodiment, when humidity value is less than condensation humidity threshold in second Room, then the operation that maintains air-conditioning current State is constant.

In embodiment, control method further includes：According to the psychrometric difference of the first indoor humidity value and the first outside humidity value Value, determines the initial wind-speed gear of fresh air pattern.When the humidity differences of the first indoor humidity value and the first outside humidity value are smaller When, the outdoor air of unit volume can be less by the amount of room air " neutralization " to condensation humidity threshold, therefore can will be new The initial wind-speed gear of wind pattern is determined as higher wind-speed gear, to improve the conveying capacity of outdoor air；When the first interior is wet When the humidity differences of angle value and the first outside humidity value are larger, the outdoor air of unit volume can be by room air " neutralization " extremely The amount of condensation humidity threshold is more, therefore can the initial wind-speed gear of fresh air pattern be determined as lower wind-speed gear, with Extra power consumption when operation of air conditioner fresh air pattern is reduced, it is energy-saving.

For example, the humidity differences of the first indoor humidity value and the first outside humidity value are less than or equal to 20% relative humidity When, the initial wind-speed gear of fresh air pattern is determined as high wind wind shelves；The humidity of first indoor humidity value and the outer humidity value of second Room When difference is more than 20% relative humidity, the initial wind-speed gear of fresh air pattern is determined as apoplexy wind shelves, etc..

In this way, can be according to the first Room acquired in the first indoor humidity value and step S102 acquired in step S101 The humidity differences of outer humidity value determine initial wind-speed gear when operation of air conditioner fresh air pattern in step S105.
