Corresponding above-described embodiment, the present invention also propose a kind of computer readable storage medium.
The computer readable storage medium of the embodiment of the present invention has and is stored in instruction therein, when the instruction is performed When, the control method for the air conditioner that the above embodiment of the present invention proposes can be performed in air conditioner.
Computer readable storage medium according to an embodiment of the present invention, air conditioner can be made and meanwhile meet user to temperature and The comfort requirement of humidity, and being capable of save the cost.
Corresponding above-described embodiment, the present invention also propose a kind of control device of air conditioner.
As shown in figure 4, the control device of the air conditioner of the embodiment of the present invention, comprising: first, which obtains module 10, second, obtains Module 20, third obtain module 30 and control module 40.
Wherein, first module 10 is obtained in air conditioner refrigerating operaton, obtaining set temperature, setting humidity;Second Module 20 is obtained to be used to obtain setting water capacity according to set temperature and setting humidity;It is current for obtaining that third obtains module 30 Indoor environment temperature, current indoor ambient humidity and current indoor heat exchanger coils temperature, the second acquisition module 20 are also used to root Current water capacity and existing dew point temperature are obtained according to current indoor environment temperature and current indoor ambient humidity;Control module 40 is used In to the size between size relation, setting water capacity and the current water capacity between set temperature and current indoor environment temperature Relationship is judged, and is carried out according to judging result, existing dew point temperature and current indoor heat exchanger coils temperature to air conditioner Temperature and Humidity Control.
When air conditioner is switched on and runs, user can carry out parameter setting to air conditioner, pass through the given setting temperature such as remote controler Degree is the target temperature and setting humidity, that is, air conditioner operation target humidity etc. of air conditioner operation, so that air conditioner is set according to this Fixed target temperature and target humidity carry out temperature adjusting and humidity regulation.If user booting when not to temperature and humidity into Row setting, then to shut down before this when air conditioner set temperature, setting humidity as this operation when set temperature and setting Humidity.
In one embodiment of the invention, the second acquisition module 20 can obtain pair of temperature, humidity and water capacity in advance It should be related to, and recording and storage corresponding relationship in table form.As a result, after obtaining set temperature and setting humidity, the Two acquisition modules 20 can table look-up to obtain setting water capacity.
In one particular embodiment of the present invention, the corresponding relationship of temperature, humidity and water capacity can be as shown in table 1.
In one embodiment of the invention, third obtains module 30 can pass through indoor environment temperature sensor, room respectively Cup is worked as in the indoor heat exchanger coil temperature sensor acquisition of interior ambient humidity sensor and corresponding indoor heat exchanger coil pipe setting Interior environment temperature, current indoor ambient humidity and current indoor heat exchanger coils temperature.
Then, the second acquisition module 20 can table look-up according to current indoor environment temperature and current indoor ambient humidity 1 obtains Current water capacity.
In one embodiment of the invention, the second acquisition module 20 can also obtain temperature, humidity and dew-point temperature in advance Corresponding relationship, and recording and storage corresponding relationship in table form.It is obtaining current indoor environment temperature as a result, and is working as After preceding indoor environment humidity, the second acquisition module 20 can table look-up to obtain existing dew point temperature.
In one particular embodiment of the present invention, the corresponding relationship of temperature, humidity and dew-point temperature can be as shown in table 2.
Control module 30 is less than or equal to current indoor environment temperature in set temperature and setting water capacity is less than or equal to currently When water capacity, air conditioner cooling, dehumidifying operation are controlled, and be less than or equal to current indoor environment temperature and set contain in set temperature When moisture is greater than current water capacity, the cooling of control air conditioner, moisturizing operation, and it is greater than current indoor environment temperature in set temperature Degree and setting water capacity be less than or equal to current water capacity when, control air conditioner heat preservation, dehumidifying operation and set temperature be greater than works as Preceding indoor environment temperature and setting water capacity be greater than current water capacity when, control air conditioner heat preservation, moisturizing operation.
Wherein, to air conditioner carry out Temperature and Humidity Control before, control module 30 can control the compressor of air conditioner with The rule operation formulated according to current indoor environment temperature and set temperature.I.e. current indoor environment temperature is adjusted to setting Temperature is the operation of target control compressor, if current indoor environment temperature is higher relative to set temperature, improves compressor Running frequency, if current indoor environment temperature reduces the running frequency of compressor near or above set temperature.
The air conditioner of the embodiment of the present invention may include dehumidification valve, also may not include dehumidification valve.
When air conditioner includes dehumidification valve, by control dehumidification valve throttling work, and controls restricting element and be in standard-sized sheet shape State, so that air conditioner dehumidifies.
Specifically, air conditioner may include the compressor being sequentially connected, outdoor heat exchanger, restricting element and indoor heat exchange Device, and the indoor fan being correspondingly arranged on indoor heat exchanger, wherein the refrigerant pipeline of indoor heat exchanger includes two parts, and one The both ends of part refrigerant pipeline are directly corresponding with restricting element and compressor to be connected;One end of another part refrigerant pipeline is by removing Wet valve is connected with restricting element, and the other end is connected with compressor.Wherein, dehumidification valve and restricting element can be electric expansion valve.
It is shown in a fully open operation by the restricting element in control above structure, and controls dehumidification valve and carry out throttling work, with Dehumidification equipment is controlled to open.At this point, the high pressure gaseous refrigerant come out from compressor after outdoor heat exchanger exchanges heat, becomes high Warm high-pressure liquid refrigerant, then a part of high temperature and pressure liquid refrigerant be directly entered a part of refrigerant pipeline of indoor heat exchanger into After row heat exchange, it is changed into low-temp low-pressure liquid refrigerants and flows back into compressor;Another part high temperature and pressure liquid refrigerant is through dehumidifying After valve throttling, become low-temp low-pressure liquid refrigerants, then after another part refrigerant pipeline of indoor heat exchanger carries out heat exchange Flow back into compressor.Wherein, a part of refrigerant pipeline of indoor heat exchanger is realized as condenser to indoor heating, another Part refrigerant pipeline is realized as evaporator to indoor a large amount of dehumidifying, and then is realized to indoor constant temperature dehumidification, is guaranteed indoor Humidity comfort.
