Detailed description of the invention
Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
The invention provides a kind of control method of air-conditioner, with reference to Fig. 1, in one embodiment, the control method of this air-conditioner comprises:
The indoor environment temperature in S10, detection room, air-conditioner place.
In air-conditioner running, detect the indoor environment temperature in this room, air-conditioner place in real time.In one embodiment, can at multiple positions in this room, air-conditioner place (as entreated in a room and surrounding position) set temperature collector, to gather the temperature of each position, then the temperature value that multiple Temperature sampler gathers is averaged as the indoor environment temperature in this room, air-conditioner place, the indoor environment temperature that obtains can be made more accurate.In another embodiment, by the acquisition for mobile terminal indoor environment temperature communicated to connect with this air-conditioner, then the indoor environment temperature of acquisition is sent to air-conditioner, this mobile terminal can be mobile phone or panel computer etc., and this mobile terminal also can have multiple.
S11, judge whether according to the target temperature of setting and the indoor environment temperature of this detection the unlocking condition meeting energy-saving and noise-reducing, if the target temperature of setting and the indoor environment temperature of this detection meet the unlocking condition of energy-saving and noise-reducing, then perform step S12, if the target temperature of setting and the indoor environment temperature of this detection are discontented with the unlocking condition of sufficient energy-saving and noise-reducing, then perform step S13.
The target temperature of this setting is the expectation cryogenic temperature that user sets when air-conditioner is opened, and also can be in this air-conditioner running, the expectation cryogenic temperature that user resets, namely this target temperature value can by user according to actual needs, be arranged voluntarily.By remote controller setting target temperature, the input equipment also by input equipment or wireless connections with this air-conditioner wired connection sets target temperature, also can by the human-computer interaction interface setting target temperature of air-conditioner itself.
In one embodiment, judge whether that the step of the unlocking condition meeting energy-saving and noise-reducing is specially according to the target temperature of setting and the indoor environment temperature of this detection: when this air-conditioner is at refrigeration mode, if the difference of the target temperature of setting and the indoor environment temperature of this detection is more than or equal to the first preset temperature threshold values, then judge the unlocking condition meeting energy-saving and noise-reducing, if the difference of the target temperature of setting and the indoor environment temperature of this detection is less than the first preset temperature threshold values, then judge the unlocking condition of discontented sufficient energy-saving and noise-reducing; When this air-conditioner is at heating mode, if the difference of the target temperature of setting and the indoor environment temperature of this detection is less than or equal to the second preset temperature threshold values, then judge the unlocking condition meeting energy-saving and noise-reducing, if the difference of the target temperature of setting and the indoor environment temperature of this detection is greater than the second preset temperature threshold values, then judge the unlocking condition of discontented sufficient energy-saving and noise-reducing.
This first preset temperature threshold values can be arranged according to actual needs, as usually this first preset temperature threshold values being set to 1 DEG C.When the difference of indoor environment temperature of the target temperature set and this detection is more than or equal to 1 DEG C, thinks that the refrigeration of air-conditioner has reached the setting of user, can energy-saving and noise-reducing adjustment be carried out; When the difference of indoor environment temperature of the target temperature set and this detection is less than 1 DEG C, think that the refrigeration of air-conditioner is also without the setting reaching user, air-conditioner needs to continue to run according to current operational factor to freeze, energy-saving and noise-reducing adjustment can not be carried out, namely need the refrigeration first ensureing air-conditioner, just can carry out energy-saving and noise-reducing adjustment.
This second preset temperature threshold values can be arranged according to actual needs, as usually this second preset temperature threshold values being set to-1 DEG C.When the difference of indoor environment temperature of the target temperature set and this detection is less than or equal to-1 DEG C, thinks that the heating effect of air-conditioner has reached the setting of user, can energy-saving and noise-reducing adjustment be carried out; When the difference of indoor environment temperature of the target temperature set and this detection is greater than-1 DEG C, think that the heating effect of air-conditioner is also without the setting reaching user, air-conditioner needs to continue to run according to current operational factor to freeze, energy-saving and noise-reducing adjustment can not be carried out, namely need the heating effect first ensureing air-conditioner, just can carry out energy-saving and noise-reducing adjustment.
S12, reduce the operational factor of this air-conditioner.

Namely the indoor load of air-conditioner and the rotating speed of indoor fan have functional relation, the outdoor heat exchange amount of air-conditioner and the rotating speed of off-premises station have functional relation, the power consumption of compressor and the frequency of compressor have functional relation, the power consumption of indoor set and the rotating speed of indoor set have functional relation, and the power consumption of off-premises station and the rotating speed of off-premises station have functional relation.Obtained one group of operational factor (x, y, z) of air-conditioner by above-mentioned formulae discovery, the compressor of air-conditioner, indoor fan and outdoor fan are run according to the operational factor calculated, reduce energy consumption and the noise of air-conditioner.
When the target temperature of setting and the indoor environment temperature of this detection meet the unlocking condition of energy-saving and noise-reducing, concrete, in cooling mode, when the difference of indoor environment temperature of the target temperature set and this detection is more than or equal to the first preset temperature threshold values, and in a heating mode, when the difference of indoor environment temperature of the target temperature set and this detection is less than or equal to the second preset temperature threshold values, indoor load reduces, now, the running frequency of compressor can be reduced according to preset rules, as the running frequency of current compressor reduced to original 90%, the rotating speed of the outdoor fan matched with the running frequency of this compressor also decreases (because now not needing so large air quantity to carry out condenser exchange), the rotating speed of the indoor fan mated with indoor load also reduces along with the reduction of indoor load (not needing to supply too many load because now indoor).After the running frequency of compressor being reduced, the rotating speed of indoor fan and the rotating speed of outdoor fan can be drawn according to above-mentioned formula.
S13, keep the operational factor of this air-conditioner.
In this step, air-conditioner is made to continue to run according to the current operating parameter of air-conditioner, to reach the refrigerating/heating effect that user requires.
With reference to the second embodiment flow chart that Fig. 2, Fig. 2 are the control method of air-conditioner of the present invention.
