Description of drawings
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
Fig. 1 is air-conditioner selection of speed flow chart of the present invention;
Fig. 2 is air-conditioner system figure one;
Fig. 3 is air-conditioner system figure two;
Fig. 4 is the Electric Machine Control schematic diagram;
Fig. 5 is common air-conditioning device selection of speed flow chart.
The specific embodiment
Air-conditioner has defined minimum speed and two border rotating speeds of maximum speed under the various patterns on stream, and air-conditioner must be within the scope of these two rotating speeds in actual use so, goes beyond the scope, and can cause that the air-conditioner operation is undesired.Define the value range under the various rotating speeds, under the refrigeration mode, maximum speed is ZLZG, and minimum speed is ZLZD, and under the heating mode, maximum speed is ZRZG, and minimum speed is ZRZD, and under the air supply pattern, maximum speed is SFZG, and minimum speed is SFZD.Above ZLZG, ZRZG, SFZG can be identical, can be not identical yet, ZLZD, ZRZD, SFZD can be identical, also can be not identical.
Definition can be adjusted the progression N of wind speed, and when then the user controlled air-conditioner wind speed round progression and is n, the rotating speed RPM of air-conditioner wind wheel calculated by following formula:
RPMn=ZD+(ZG-ZD)/N*n
Wherein ZD can be ZLZD, ZRZD, and SFZD, ZG can be ZLZG, ZRZG, SFZG.Respectively lower limit and the higher limit of air-conditioner wind wheel speed.
Air-conditioning rotating speed minimum mainly is to consider that from stability and the security aspect of motor speed wind speed is excessively low, and motor speed can be not steady, can occur dangerous in the air-conditioner cooling and warming process yet.The highest mainly is limited by motor speed restriction and noise, and wind speed is too high, and level of noise can surpass in the national standard restriction to level of noise.
Like this, the user passes through to adjust the n value, the rotating speed of adjustment wind wheel that then can be linear, if the N value is larger, and the then every variation 1 of n value, then the rotation speed change of wind wheel is smaller, reaches the effect of stepless speed regulation.N=100 for example, then the every adjustment of user n value 1, and then wind speed round increases or reduces 1%.
Referring to Fig. 1, can adjust the user under the pattern (freeze, heat, blow etc.) of rotating speed, after the start, select the rotation speed n value, if think that rotating speed will increase, then by remote controller key, whenever press once, wind speed round increases an increment to n1, is increased to the maximum (top) speed N that air-conditioner allows always.If think that rotating speed will reduce, then by remote controller key, whenever to press once, wind speed round is reduced to n2, is reduced to the minimum speed 1 that air-conditioner allows always.By increasing this function, can make the user select freely suitable oneself wind speed round.
That is to say, by remote controller or controller, can be manually or automatically change the rotating speed desired value, then motor can change rotating speed of target into by current rotating speed.
The value of N is one, and excellent selective value is between 5-200 greater than 0 integer, and numerical value is larger, then adjust more carefully, noise and air quantity change very littlely between any two adjacent rotating speeds, reach and seamlessly transit, more can reach the advantage of the technical program, the scope of user selection is just larger.That especially preferentially select is 10-100.
Take certain separated wall hanging type air conditioner as example:
In the refrigeration mode, ZLZD=700RPM, ZLZG=1200RPM, N=100, then air-conditioner can be selected from regulating for totally 100 times every the 5RPM Primary regulation between the 700-1200RPM by the user, the user is by remote controller or controller, can be manually or automatically change rotating speed desired value n, and then motor can change rotating speed of target into by current rotating speed.In conjunction with RPMn=ZD+ (ZG-ZD)/N*n formula, then:
RPMn=700+ (1200-700)/100*n, wherein the value of n is 1-100.By this formula, can calculate actual speed corresponding to each rotating speed shelves value between any 1-100.
In addition, between 700-1200RPM, also can again get new tachometer value as upper, lower limit, still take refrigeration mode as example, ZLZD=800RPM, ZLZG=1100RPM, N=100, in conjunction with RPMn=ZD+ (ZG-ZD)/N*n formula, then:
RPMn=800+ (1100-800)/100*n, wherein the value of n is 1-100.By this formula, can calculate actual speed corresponding to each rotating speed shelves value between any 1-100.
Air supply pattern and heating mode, method and above-mentioned identical.
The present invention is more to user's selection, and is more humane, and this method for designing do not need to increase cost, and the rotating speed of wind wheel is easy to realize by the software of electric-controlled parts.
