The specific embodiment
The present invention will be described in detail below in conjunction with accompanying drawing.
With reference to figure 1, illustrate the structural representation of an embodiment of a kind of air-conditioner of the present invention.As shown in the figure, comprise display control panel 14, indoor set control panel 11, off-premises station control panel 12 and be arranged at the compressor 13 of off-premises station.
Described display control panel 14 is used to show the operation of air conditioner situation;
Described control panel 14 can be converted to control signal with the frequency change value that receives, and this signal is issued indoor control panel 11;
Described frequency change value can be by directly input on display control panel 14 of user, perhaps by the signal of the reception of the joint on the display control panel from remote controller 10;
Described indoor set control panel 11 can be by carrying out the transmission of control signal between wired or wireless mode and the described off-premises station control panel 12;
The control signal that described off-premises station control panel 12 comes 11 transmissions of indoor set control panel exports described compressor 13 to and regulates and control.
Can be with reference to figure 2 and explanatory note thereof in the present embodiment to the detailed process of compressor frequency control.
With reference to figure 2, illustrate the flow chart of an embodiment of control method for frequency embodiment illustrated in fig. 1.As shown in the figure, may further comprise the steps:
Step S21 obtains the manually frequency change value of input of user.
In this step, described frequency change value can be the actual frequency number that will increase and decrease, for example ± 50Hz, ± 76Hz etc., wherein "+" expression increases, and "-" expression reduces; Also can be the change frequency that frequency increases, for example ± 10, ± 15 etc., its concrete use will be introduced hereinafter.
The described user manually mode of input then can be by remote controller 10 inputs, when being the actual frequency number that will increase and decrease for the frequency change value, then can import by the numerical key on the described remote controller 10; So during the change frequency that frequency is increased, the compression number of button that then can be by the increase and decrease of the sign on the described remote controller 10 is imported.
Certainly, also can import by the display control panel 14 of described air-conditioner, since similar with the input mode of described remote controller 10, so be not described further.
Step S22 judges whether user's switch of manually adjusting frequency is opened, if, execution in step S23 then, otherwise execution in step S24.
The described switch of manually adjusting frequency is equivalent to the enable switch that manual frequency is adjusted, and it can be arranged on the described display control panel 14 of air-conditioner, also can be arranged on the described remote controller 10 (the independent button that can be provided with, or Macintosh is set).
Manually the adjust frequency current state of switch of this user is stored by the register that is provided with in the described air conditioner room unit, carries out this step when judging, only needs read data and judge from this register.
Step S23, judge apply the frequency change value that step S21 imported after, whether surpass setting value, if, execution in step S25 then; Otherwise, execution in step S24.
Wherein, described setting value is the scope that the maximum of the compressor of this air-conditioner can be worked, for example 5Hz～130Hz.The operating frequency of supposing current compressor is X, so this step judge then that X adds the above frequency change value (comprising sign) but after whether exceeded the maximum working range of this compressor.
When being the frequency values of the directly reality of input for described frequency change value, then this step adds the above actual frequency values with the operating frequency of current compressor, X ± 50Hz for example, X ± 100Hz.When being the frequency change number of times, then carry out following calculating for described frequency change value:
The operating frequency of current compressor+(described change frequency (comprising sign) * frequency preset step-length) for example, X ± 10 * frequency preset step-length etc.
In a preferred embodiment of the present invention, described frequency preset step-length is 3Hz to 20Hz, preferably 5Hz.And this frequency preset step-length can be made amendment as required.
Step S24 applies.
That is, when judging the operating frequency range that surpasses described compressor, then described frequency change value is applied to the work at present frequency of described compressor, makes and work under the frequency of described compressor after applying by previous step.
This step finishes back execution in step S26.
Step S25 will set value as frequency values.
That is, exceeded the operating frequency range (just described setting value) of described compressor 13 after applying described frequency change value by the previous step judgement, then directly set value as frequency values with this, described compressor 13 is just worked under the frequency of this setting value.For example:
When described frequency change value is actual frequency, the operating frequency range of supposing described compressor 13 is 30Hz～130Hz, the operating frequency of current compressor is 100Hz, and described frequency change value is+40Hz, 100Hz+40Hz=140Hz is just greater than 130Hz so, thereby this moment is with the operating frequency of this 130Hz as described compressor.
When described frequency change value when distinguishing the rate change frequency, still with the data in the previous example, if described frequency change value is-10, frequency step is 8Hz, 100Hz-10 * 8Hz=20Hz so, less than the operating frequency lower limit 30Hz of described compressor, thereby this moment is with the operating frequency of this 30Hz as described compressor.
Step S26 finishes.
Need to prove that when described user manually adjusts frequency switch when closing, described air-conditioner can be with the mode operation of convertible frequency air-conditioner, also can be with the mode operation of fixed frequency air conditioner.
Beneficial effect of the present invention is as follows:
1, with respect to convertible frequency air-conditioner, the present invention has realized that the operation of air conditioner frequency is controlled.That is to say that frequency changer can only carry out automatic compressor operating frequency adjustment according to the difference of design temperature and environment temperature, and the present invention has realized the function of FREQUENCY CONTROL frequency voluntarily to the user, simultaneously also changeable time automatic frequency control function (by the described user switch of manually adjusting frequency) operated more humane;
2, because frequency can artificially be regulated, thereby control and properly then further can realize electricity-saving function; Use more comfortable.
For example, if 20 ° of indoor environment environment temperatures, 16 ° of design temperatures, according to the automatic frequency running, compressor frequency can carry out the 100Hz running; If adopt mode of the present invention, then can adjust according to setpoint frequency, if at existing 100Hz (instantaneous power 1500W, power consumption in one hour is exactly 1.5 degree) reduction frequency 40Hz on the basis, compressor carries out 60Hz running (instantaneous power 1000W, power consumption in one hour is exactly 1 degree), so turning round one hour is comparable automatic mode power saving 0.5 degree;
In like manner, if frequency drops to 50Hz, just identical with fixed frequency air conditioner, this machine can reach equally and decide the frequency power saving if 4 grades of product efficiencies 3.40 of convertible frequency air-conditioner can be equivalent to decide 1 grade of efficiency level of frequency.
If frequency drops to 50Hz following (40Hz), and is also lower than fixed frequency air conditioner operating frequency, then more energy-conservation under the situation that does not influence cooling or heating effect.
Foregoing description is example with the CHINESE REGION, and the fixed frequency difference that each is regional is generally 50HZ as the CHINESE REGION fixed frequency, and Korea S's area fixed frequency is generally 60HZ.
3, compatibility of the present invention the fixed frequency air conditioner and the convertible frequency air-conditioner function of existing market, realized FREQUENCY CONTROL in any compressor tolerance frequency scope.
Above disclosed is preferred embodiment of the present invention only, can not limit the present invention's interest field certainly with this, and therefore the equivalent variations of doing according to claim of the present invention still belongs to the scope that the present invention is contained.
