The specific embodiment
Below in conjunction with drawings and Examples the present invention is further described.
Embodiment one
Referring to Fig. 1 and Fig. 2, the variation diagram and the frequency diagram of indoor temperature during with the different set operating frequency for the embodiment of the invention one, as shown in Figure 2: ordinate is the frequency Hz of compressor, abscissa is the shelves number n of the optional operating frequency of user, just set value, as can be seen from the figure, the highest frequency Fmax of compressor is 120 hertz, and low-limit frequency Fmin is 18 hertz, also have two intermediate frequency values available in addition, be respectively 100 hertz and 37 hertz, setting operating frequency is that inhomogeneous setting (can also have more more options value certainly,, perhaps do not establish a grade number, direct frequency modulation rate value all belongs to the control mode that is equal to of the present invention, does not exemplify one by one here).
During operation of air conditioner, the user sets indoor target temperature earlier, if do not adjust, then be the indoor target temperature of systemic presupposition or the indoor target temperature that the user operated operation last time, select the operation operating frequency then, the user can select four operating frequencies, be respectively when n=0, corresponding operating frequency is Fmax, when the user selects this pattern, convertible frequency air-conditioner adopts the VFC mode operation, and the compressor maximum running frequency can reach 120 hertz, and adjusts rotating speed according to the difference of indoor target temperature of setting and actual indoor temperature, when the indoor target temperature of setting and actual indoor temperature difference are big, 120 hertz of operating frequency trends, when the indoor target temperature of setting and actual indoor temperature difference hour, the low-limit frequency that the operating frequency trend is 18 hertz is moved.The technology of adjusting running frequency according to the temperature difference belongs to widely used public technology, is not described in detail herein.When the user selects n=1, corresponding operating frequency is 100 hertz, this operating frequency is less than highest frequency Fmax, and when the user selected this operating frequency, compressor was that maximum running frequency adopts the VFC pattern to carry out the refrigerating/heating operation with 100 hertz of this operating frequencies; When the user selects n=2, corresponding operating frequency is 37 hertz, this operating frequency is greater than Fmin, when the user selects this operating frequency, before the indoor target temperature that reaches user's setting, compressor is that maximum running frequency adopts the VFC pattern to carry out the refrigerating/heating operation with this operating frequency; When the user selected n=3, compressor adopted the work of minimum operation frequency, and it is the same that all the other do not state part.
Disclose as the present invention, in the present embodiment, the user can select operation n=0 by button on the remote controller or the operating key on the indoor set ..., each operating frequency operational mode among the N.
As can be seen from Figure 2, work as n=1, the operating frequency during n=2 is not equally distributed.Distribute if adopt evenly, the n=1 in the present embodiment, the operating frequency during n=2 is respectively 86 hertz, 52 hertz.But be actually: n=1 relatively presses close to n=0, i.e. the position of Fmax; N=2 relatively presses close to n=3, i.e. the position of Fmin.
Disclose as the present invention, in the present embodiment, the numerical value of the operating frequency that the user can set is when moving according to frequency-changeable compressor, compressor and the less Frequency point of pipe-line system vibration, operating point just, as the operating frequency numerical value of user's setting, to reduce system noise and the system vibration when this point moves, the life-span of improving system simultaneously.In the present embodiment, compressor operating when 100 hertz or 37 hertz, have relatively near lower system vibration and system noise during other running frequency.
Owing to the resonance reason causes noise bigger, so will avoid, the operation noise during such as 37 hertz is less at some running frequency point for convertible frequency air-conditioner, might be adjacent 36 hertz and the 38 hertz noise height when all moving than 37 hertz.
Further analyze in conjunction with Fig. 1, when adopting the different operating frequency to the influence of indoor temperature.Ordinate is an indoor temperature among the figure, and abscissa is the time, and this figure shows indoor temperature 31 degree, adopts different operational modes after, when the indoor target temperature 26 that reaches user's setting is spent, the situation of change of indoor temperature.
Wherein, when C0 is n=0 in the present embodiment, when promptly compressor adopts highest frequency Fmax frequency, the change curve of indoor temperature, as can be seen, indoor temperature is through just reaching indoor target temperature 26 degree of setting in 8 minutes from curve; When C1 is n=1 in the present embodiment, when promptly compressor adopts 100 hertz, the change curve of indoor temperature, as can be seen, indoor temperature is through just reaching indoor target temperature 26 degree of setting in 25 minutes from curve; When C2 is n=2 in the present embodiment, when promptly compressor adopts 37 hertz, the change curve of indoor temperature, as can be seen, indoor temperature is through reaching indoor target temperature 26 degree of setting in 40 minutes from curve.
Since traditional control model often the indoor target temperature that reaches setting fast as control logic, often adopt the setting in the n=0 pattern, the shape of curve C 0 among indoor temperature change generated in case situation that it is actual such as the figure, can see in 8 minutes, the variable quantity of indoor temperature is 5 degree, is on average just once reducing less than two minutes, for older, the age children, or hinder the patient, this variations in temperature is too violent, and the adaptive capacity of human body is limited, sensation can be felt bad very much, can only be fit to a minority and use.Be lower than the n=1 of peak frequency Fmax and the operating frequency of n=2 correspondence and adopt, then time corresponding is respectively 25 minutes and 75 minutes; It is respectively 5 minutes and 15 minutes that indoor temperature reduced for 1 used time of degree, because variations in temperature is slow, thus adapt to for user Geng Yi, and feeling that temperature is not in good time, also can in time adjust, improve comfortableness.
Another object of the present invention is the control method that has disclosed a kind of convertible frequency air-conditioner, after setting indoor target temperature, comprises three steps, a, enters operating frequency pattern is set; B, in a plurality of operating frequencies, select the button of the frequency of user's tendency; C, affirmation, the frequency of deactivating is provided with pattern.The operating sequence of this method is to set indoor target temperature earlier, then sets operating frequency; Certainly, its reversed order is come also to be fine, promptly set operating frequency earlier, then set indoor target temperature again, equally also can realize purpose of the present invention, and what influence is final effect do not had.
Promptly by button, just mode key is set the pattern that is provided with that enters operating frequency, adopt the unified step that is provided with in the present embodiment, see Fig. 4, show according to display unit that the pattern that present mode is set to the operating frequency correspondence of user's setting gets final product being provided with in the step process of operating frequency.
