Description
Technical field
The present invention relates to a kind of control method of transducer air conditioning.
Background technology
Because transducer air conditioning can be along with the automatic regulating frequency of the variation of air conditioner load, and then change compressor rotary speed to adapt to load variations.Along with the raising of people's awareness of saving energy, transducer air conditioning is also used more and more widely.
At present, the control method of convertible frequency air-conditioner adopts more: main frame is provided with temperature according to indoor and outdoor surroundings and user, carry out FREQUENCY CONTROL by setup program automatically, and the user cannot be provided with frequency operational mode and parameter, and there is following defective in this control method:
1, because inaccurate to the load prediction of concrete air conditioner surroundings, frequency is often higher or less than normal, and energy consumption and noise are big with regard to causing, heating and cooling wait problem slowly for this;
2, air-conditioning can move a period of time at high band usually, but the efficiency of high band is on the low side, noise is bigger than normal; Therefore, though the high frequency operation has the advantage of rapid temperature rise and drop, caused the problem of operation energy consumption and noise also;
3, in the frequency change process, can produce noise, certain customers are relatively more responsive under specific circumstances;
In a word, the user of existing transducer air conditioning can't select operating modes of air conditioner according to self needs, when realizing automatic frequency-conversion control, has brought the problem of noise, efficiency, comfortableness aspect, needs to do further to improve.
Summary of the invention
The object of the present invention is to provide a kind of control method of transducer air conditioning, in use, the user can set according to self needs, has improved the comfortableness height, makes that this air-conditioner is humanized.
Its technical scheme is as follows:
A kind of control method of transducer air conditioning, this method comprise the steps: A, open transducer air conditioning; The controller or the control panel of B, operation transducer air conditioning, start the air conditioning mode selection function, (a, automatic mode: air-conditioner is according to the running frequency of rate of change with the rate temperature change fiducial value adjusting air-conditioner of setting of environment temperature to select wherein a kind of mode of operation in following three kinds of patterns; B, speed limit pattern: the frequency of air-conditioner is moved under the highest frequency that is not higher than setting; C, constant speed pattern: air-conditioner is by the frequency continuous service of a certain setting); C, transducer air conditioning carry out work under selected pattern.
The present invention is owing to have a model selection function, and the user can select corresponding work mode according to self needs, can provide more selection for the user, in use, has the family can consider that actual requirements such as energy consumption, noise and comfortableness operate.
The further technical scheme of the present invention is:
1, under the situation of selecting " automatic mode ", air-conditioner is selected the initial frequency operation according to the difference of environment temperature and design temperature, after operation certain hour section, accounting temperature mean change speed V, and the rate temperature change V0 of this rate temperature change V and setting compared; If A＞(V0-V)/V0＞B, the running frequency of then controlling this air-conditioner is constant, if (V0-V)/V0 〉=A, then with air-conditioner running frequency heighten, if (V0-V)/V0≤B, then the running frequency of air-conditioner is turned down.
Set default frequency in air-conditioner, under the situation of selecting " automatic mode ", it is this default frequency that described air-conditioner is selected initial frequency, and described default frequency is air-conditioning default frequency or user's setpoint frequency.
2, selecting under the situation of " speed limit pattern ", select the operating frequency of air-conditioner according to the difference of outdoor temperature and environment temperature and design temperature, but this frequency must not be higher than the qualification frequency.
The qualification frequency that qualification frequency that described air-conditioner qualification frequency is the air-conditioner acquiescence or user set.
3, under the situation of selecting " constant speed pattern ", air-conditioner moves by setpoint frequency and remains unchanged.Described air-conditioner setpoint frequency is the setpoint frequency of air-conditioner acquiescence or the frequency that the user sets.
Select the FREQUENCY CONTROL pattern of air-conditioner and relevant parameters is set by remote controller, remote controller is stored in the pattern of selection and the parameter of setting in the memory chip, remote controller transfers to air-conditioner host computer control chip with the pattern of selection and the parameter of setting by the coded format of setting, by the operation of control chip control air-conditioner host.
In sum, advantage of the present invention is: in use, the user can set according to self needs, has improved the comfortableness height, makes that this air-conditioner is humanized.This air-conditioner not only has the advantage of general transducer air conditioning, can also set according to user's needs simultaneously, has overcome the problem of general transducer air conditioning aspect noise, efficiency, comfortableness.
Description of drawings
Below in conjunction with accompanying drawing embodiments of the invention are elaborated:
Fig. 1 is in the embodiment of the invention, the theory diagram of controller used thereby;
Fig. 2 is in the embodiment of the invention, the control flow chart under " automatic mode ";
Description of reference numerals:
1, IR remote controller, 2, the air-conditioner host controller, 3, keyboard, 4, memory chip, 5, the remote controller master chip, 6, display unit, 7, the infrared signal transmitter unit, 8, the infrared signal receiving element, 9, the MCU control chip.
The specific embodiment
As shown in Figure 1, controller used thereby comprises IR remote controller 1 and air-conditioner console controller 2 among this embodiment, IR remote controller 1 includes keyboard 3, memory chip 4, remote controller master chip 5, display unit 6 and infrared signal transmitter unit 7, and air-conditioner console controller 2 comprises infrared signal receiving element 8 and MCU control chip 9.
As shown in Figure 2, a kind of control method of transducer air conditioning, this method comprises the steps:
