Detailed description of the invention
The drawings described herein are used to provide a further understanding of the present invention, constitutes part of this application, this hair Bright illustrative embodiments and their description are used to explain the present invention, and are not constituted improper limitations of the present invention.In the accompanying drawings:
Fig. 1 is the flow chart of the air-conditioning temperature/humidity control method of the embodiment of the present invention.
Specific embodiment
In the following detailed description, a large amount of specific details are proposed, in order to provide a thorough understanding of the present invention.But It will be understood by those within the art that implementable present invention without these specific details.In other cases, without detailed Well-known method, process, component and circuit are carefully described, in order to avoid influence the understanding of the present invention.
It include: that detection room temperature and interior are wet in conjunction with air-conditioning temperature/humidity control method shown in Figure 1, of the invention Degree;Target temperature t and room temperature T and target humidity rh and indoor humidity RH is compared;According to comparison result to pressure Contracting unit frequency and interior machine rotation speed of fan are adjusted, and are adjusted by compressor frequency and interior machine rotation speed of fan to room temperature Section, is adjusted humidity by interior machine rotation speed of fan.
By comparing room temperature and indoor humidity with target temperature and target humidity simultaneously, and tied according to comparison The mode that fruit is adjusted is selected according to the relativeness between room temperature and indoor humidity and target temperature and target humidity Suitable adjustment mode, so that room temperature and indoor humidity can be properly arrived at adjustment target, so that Indoor Temperature Degree and indoor humidity can meet user's needs simultaneously, improve the comfort level that user uses air-conditioning.
Wherein target temperature and target humidity can be set when leaving the factory, can also be switched on it carrying out air conditioner refrigerating After be set by the user, local weather conditions information sets itself can also be acquired, by air-conditioning so as to flexible choice setting Mode enables target temperature and target humidity to better meet user demand.It is set by target temperature and target humidity After good, so that it may carry out the detection of room temperature and indoor humidity by interior sensor.
Preferably, air-conditioning temperature/humidity control method further include: indoor humidity is adjusted by solution dehumidification film.
The functional relation of the moisture removal of solution dehumidification film and interior machine revolving speed are as follows: Q=k*r+b, wherein Q is solution dehumidification film Moisture removal, k are proportionality coefficient, and r is outdoor fan revolving speed, and b is amendment constant.
The step of detecting indoor temperature and humidity includes: to calculate room temperature in period first time t1 and interior is wet The mean value of degree, and compared in this, as room temperature and indoor humidity with target temperature and target humidity.By taking first Temperature and humidity mean value in time cycle t1 can fluctuate the problem of brought testing result inaccuracy to avoid temperature or humidity, Improve the accuracy of temperature and humidity detection, thus for compressor frequency and interior machine rotation speed of fan adjusting provide accurate adjusting according to According to guaranteeing the accuracy and reliability of adjusted result.Preferably, period first time t1 is 5 to 20min.
Specifically, if the step of compressor frequency and interior machine rotation speed of fan are adjusted according to comparison result includes: T > t, and RH≤rh, then compressor frequency jumps to f2, and interior machine rotation speed of fan maintains r1;If T≤t, and RH > rh, then compressor Frequency maintains f1, and interior machine rotation speed of fan jumps to r2;If T > t, and RH > rh, then compressor frequency jumps to f2, interior machine blower Revolving speed jumps to r2;If T≤t, and RH≤rh, then the step of detecting room temperature and indoor humidity is returned;Wherein f1 < f2, r1 < r2.
If parameter T > t, RH > rh, illustrates that temperature and humidity is above setting value, needs to improve compressor frequency and room Interior machine revolving speed reduces temperature, while indoor revolving speed improves, increase by the air quantity of solution dehumidification film, according to solution dehumidification public affairs Formula, moisture removal are increase accordingly, and master control borad sends instruction and compressor frequency and interior machine rotation speed of fan are jumped to f2, r2.
If parameter T≤t, RH≤rh illustrate that temperature and humidity is below setting value, booting frequency and interior machine are maintained at this time Revolving speed is constant, returns to upper one layer and continues to test room temperature and humidity.
If parameter T > t, RH≤rh, illustrate that room temperature is higher than setting value, humidity is lower than setting value, sends instruction only Compressor frequency is improved, refrigerating capacity is increased, f2 is increased to by f1, maintains interior machine revolving speed constant, booting humidity is kept, into second Predetermined period t2 carries out temperature and humidity detection.
If parameter T≤t, RH > rh, illustrates that room temperature reaches setting value, humidity is bigger than normal, needs to improve indoor revolving speed Increase moisture removal, according to solution dehumidification formula, indoor fan revolving speed is improved, and moisture removal increases, so indoor revolving speed is mentioned by r1 High r2 carries out temperature and humidity detection into the second predetermined period t2.
If compressor frequency or interior machine rotation speed of fan adjust, detect adjustment after the completion of room temperature and interior it is wet Degree, and continue that compressor frequency and interior machine rotation speed of fan is adjusted according to testing result.
The step of detecting the room temperature and indoor humidity after the completion of adjusting includes: the week the second time after the completion of adjustment In phase t2, calculate the mean value of room temperature and indoor humidity, and in this, as room temperature and indoor humidity and target temperature and Target humidity compares.Preferably, second time period t2 is 20 to 45min.
If the step of compressor frequency and interior machine rotation speed of fan are adjusted according to testing result includes: T > t, and RH ≤ rh, then compressor frequency jumps to f3, and interior machine rotation speed of fan maintains r2;If T≤t, and RH > rh, then compressor frequency maintains F2, interior machine rotation speed of fan jump to r3;If T > t, and RH > rh, then compressor frequency jumps to f3, and interior machine rotation speed of fan jumps To r3;If T≤t, and RH≤rh, then the step of detecting the room temperature and indoor humidity after the completion of adjusting is returned;Wherein f2 < F3, r2 < r3.
It is identical as the parameter adjustment principle in period first time t1 in the adjustment principle in second time period t2, here It repeats no more.
After second time period t2 adjusting parameter, room temperature and indoor humidity still cannot reach target value, Adjustment is then proceeded as described above, until all parameters are all satisfied adjustment target, room temperature and interior are wet at this time Degree reaches user's requirement, and interior has good comfort level.
The above description of the embodiment is only used to help understand the method for the present invention and its core ideas;Meanwhile for this The those skilled in the art in field, according to the thought of the present invention, there will be changes in the specific implementation manner and application range, In conclusion the contents of this specification are not to be construed as limiting the invention.
