Detailed description of the invention
In order to make object of the present invention, technical scheme and advantage clearly understand, below with reference to drawings and Examples, the present invention is described in further detail.
Refer to Fig. 1, this figure is depicted as the flow chart of an air conditioner energy-saving control method of the present invention embodiment.
As shown in Figure 1, the process that this embodiment realizes Energy Saving Control specifically comprises the steps:
Step 101: air-conditioner runs, and judges that current is day or night.
Air-conditioner runs, and refer to that air-conditioner is started working, and user has set operational mode and target temperature, or operational mode when shutting down according to last time and target temperature run.After air-conditioner brings into operation, judge that current is day or night.Specifically, daytime or evening can be judged according to current time.Such as, adopt 12 hours systems, if current time is the time between the morning 6 to 6 pm, then judge it is daytime; If time during current time between at 6 in evening at 6 in the morning, judgement is evening.Also daytime or evening can be judged according to current outdoor light intensity.Such as, setting light intensity threshold value, if current outdoor light intensity is greater than light intensity threshold value, judgement is daytime; Otherwise judgement is evening.Certainly, also can jointly judge that current is daytime or evening according to current time and current outdoor light intensity.
For current time or current outdoor light intensity, various ways can be adopted obtain.Consider that existing air-conditioner is mostly intelligent air conditioner, be provided with the network communication module of carrying out communication with Cloud Server.Therefore, preferably adopt and obtain current time or current outdoor light intensity by Cloud Server, obtain manner is simple, reliable, without the need to detecting the extra setup times module of every platform air-conditioner or outdoor optical line strength, processing module.
Step 102: whether current be daytime.If so, step 103 is performed; Otherwise representing current is evening, then go to step 109.
Step 103: be daytime if it is determined that current, then judge that whether current outdoor temperature is in rising trend.If so, step 104 is performed; Otherwise, go to step 106.
Temperature sensor is utilized to detect current outdoor temperature in real time, such as, the temperature sensor be arranged on air-conditioner outdoor unit is utilized to detect current outdoor temperature, utilize the controller on air-conditioner dash to carry out judgement process to the change of current outdoor temperature, judge the whether in rising trend or downward trend of current outdoor temperature specifically.Such as, can judge that whether current outdoor temperature raises and in rising trend gradually by the situation of change of the outdoor temperature detected in a period of time.
Step 104: judge that current outdoor temperature is in rising trend in step 103, when also namely raising gradually, judge whether the present mode of operation of air-conditioner is heating operation mode.If so, step 105 is performed; Otherwise, go to step 109.
Air-conditioner carries out operation by controller and controls, and therefore, after air-conditioner runs, the controller of air-conditioner can easily or the present mode of operation of air-conditioner.Operational mode comprises the most basic heating mode, refrigeration mode, dehumidification mode etc.This step will judge whether present mode of operation is heating mode.
Step 105: when step 103 judges that current outdoor temperature is in rising trend, step 104 judges that air-conditioner present mode of operation is heating operation mode, reduces the target temperature of air-conditioner.
If air-conditioner runs heating mode, show to need to utilize air conditioner heat-production to run, to improve indoor temperature.If now outdoor temperature is in rising trend, outdoor temperature will raise gradually, and accordingly, indoor temperature also can raise thereupon to some extent.Now, reduce the target temperature of air-conditioner, using the target temperature after reducing as the target control temperature of air-conditioner.Because indoor temperature can raise with the rising of ambient temperature, the target temperature of reduction indoor can not cause the decline to indoor temperature comfortableness, and reduce air-conditioner and reach the energy ezpenditure that higher set temperature causes, achieve the comfortableness that indoor temperature under low energy consumption regulates.
When reducing the target temperature of air-conditioner, the target temperature preferably controlling air-conditioner is followed the rising of outdoor temperature and declines.Also namely, outdoor temperature rises higher, and target temperature is lower, and the energy consumption of air-conditioner is also fewer.But, if operating modes of air conditioner is heating operation, shows that user needs air conditioner heat-production to run and realizes indoor higher temperature, thus consider the demand of the comfortableness that indoor temperature regulates and user, also will ensure indoor heating operation.Therefore, although reduce the target temperature of air-conditioner, not reduce, but control objectives temperature is not less than the first design temperature always.Wherein, the first design temperature is the temperature value that air-conditioner prestores when dispatching from the factory, and such as, is 22 DEG C.This first design temperature also can be changed by user in running.
Step 106: if step 103 judges that current outdoor temperature is not in rising trend, then judge that whether current outdoor temperature is on a declining curve again.If so, step 107 is performed; Otherwise, go to step 109.
Same, can judge whether current outdoor temperature reduces and on a declining curve gradually by the situation of change of the outdoor temperature detected in a period of time.
Step 107: if step 106 judges that current outdoor temperature is on a declining curve, when also namely reducing gradually, judge whether the present mode of operation of air-conditioner is cooling operation mode.If so, step 108 is performed; Otherwise, go to step 109.
Step 108: when step 106 judges that current outdoor temperature is on a declining curve, step 107 judges that air-conditioner present mode of operation is cooling operation mode, raises the target temperature of air-conditioner.
If air-conditioner running refrigerating pattern, show to need to utilize air-conditioner refrigerating operaton, to reduce indoor temperature.If now outdoor temperature is on a declining curve, outdoor temperature will reduce gradually, and accordingly, indoor temperature also can decline thereupon to some extent.Now, raise the target temperature of air-conditioner, using the target temperature after raising as the target control temperature of air-conditioner.Because indoor temperature can reduce with the decline of ambient temperature, the target temperature of rising indoor can not cause the decline to indoor temperature comfortableness, and reduce air-conditioner and reach the energy ezpenditure that lower design temperature causes, achieve the comfortableness that indoor temperature under low energy consumption regulates.
When raising the target temperature of air-conditioner, the target temperature preferably controlling air-conditioner is followed the decline of outdoor temperature and rises.Also namely, it is lower that outdoor temperature declines, and target temperature is higher, and the energy consumption of air-conditioner is also fewer.But, if operating modes of air conditioner is refrigerating operaton, shows that user needs air-conditioner refrigerating operaton to realize indoor lower temperature, thus consider the demand of the comfortableness that indoor temperature regulates and user, also will ensure indoor refrigerating operaton.Therefore, although raise the target temperature of air-conditioner, not reduce, but control objectives temperature is not higher than the second design temperature always.Wherein, the second design temperature is the temperature value that air-conditioner prestores when dispatching from the factory, and such as, is 27 DEG C.This is and design temperature also can be changed by user in running years old.
Step 109: keep the target temperature of air-conditioner constant.
This step is the treatment step performed according to the judged result of step 102, step 104, step 106 and step 107.
Specifically, if step 102 judges that current is evening, now, outdoor temperature change is little, then control air-conditioner according to the target temperature of user's setting to run, and target temperature is not adjusted, keep user to weigh the setting of air-conditioner target temperature, meet the demand that user regulates indoor temperature.
Or although judge current as daytime and current outdoor temperature is in rising trend through step 102 and step 103, step 104 judges that air-conditioner present mode of operation is not heating operation.So, the change of outdoor temperature can not make up the operation result of air-conditioner on the impact of indoor temperature.Therefore, also target temperature is not adjusted, keep target temperature constant.
Or, judge that current outdoor temperature remains unchanged substantially through step 103 and step 106, also target temperature do not adjusted, keep target temperature constant.
Or although although judge current as daytime and current outdoor temperature is on a declining curve through step 102 and step 106 through step, step 107 judges that air-conditioner present mode of operation is not refrigerating operaton.So, the change of outdoor temperature can not make up the operation result of air-conditioner on the impact of indoor temperature.Therefore, also target temperature is not adjusted, keep target temperature not change.
When application said method carries out Energy Saving Control to air-conditioner, consider the situation of change of outdoor temperature and the present mode of operation of air-conditioner, determine whether adjustment aim temperature and how to carry out the adjustment of target temperature, but not according to outdoor environment temperature, air-conditioner target temperature is adjusted simply, while energy-conservation, keep user to weigh the setting of air-conditioner target temperature to the full extent, meet the demand that user regulates indoor temperature, the indoor temperature realized under low energy consumption regulates comfortableness.
