Detailed Description
Preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention. And can be adjusted as needed by those skilled in the art to suit particular applications. For example, although step S600 in the drawings of the specification is when I ≦ I0And controlling the air conditioning unit to normally operate, wherein the method is finished and cannot finish continuous observation, and if the observation is performed closely, the condition that I is less than or equal to I can be realized0And then, controlling the air conditioning unit to normally operate for delta t time, and returning to the step S100 again, so that the next circulation judgment can be continued for the delta t time as long as the normal operation of the unit is detected, so as to complete the continuous monitoring of the operation condition of the air conditioning unit, and reduce the possibility of misjudgment.
An embodiment of a method for controlling an air-cooled heat pump hot water air conditioning unit according to the present invention will be described in detail with reference to fig. 1 and 2.
The air conditioning unit comprises a water inlet 1, a water outlet 2, a compressor (inside the air conditioning unit, not shown in the figure), a temperature detection component (not shown in the figure) arranged at the water outlet and a current detection component (not shown in the figure) arranged on an input circuit of the compressor, wherein one embodiment of the control method of the invention is shown in the figure 1 and comprises the following steps:
s100, controlling a temperature detection component to obtain the outlet water temperature T of a water outlet;
s200, a control circuit detection part acquires a current I of an input circuit of the compressor;
s300, obtaining the standard current I under the condition of the outlet water temperature T of the water outlet0；
S400, judging I and I0The size of (d);
s500, when I is more than I0When the water scale is cleaned, a prompt for cleaning the water scale is given;
s600, when I is less than or equal to I0And when the air conditioner is in operation, the air conditioner set is controlled to normally operate.
It should be noted that the temperature monitoring unit, the current detecting unit, etc. are all conventional parts or devices, and since there are too many devices capable of performing temperature detection and current detection, such as a thermometer, an ammeter, etc., they are not listed. In addition, the standard current I0The acquisition of the reference current is also various, for example, through practical experience, the reference current at different temperatures is detected one by one when the air conditioner unit is shipped, and then the reference current is stored in the air conditioner unit for calling when the air conditioner unit is used, or the reference current is calculated according to an empirical formula, or the reference current is calculated according to other formulas, and the like, which are not listed one by one.
Firstly, the water outlet temperature T and the current I of an input circuit are obtained through a temperature detection part and a current detection part, and then the standard current I under the condition of the water outlet temperature T of a water outlet is obtained0Comparing the two, if I is less than or equal to I0And at the moment, the air conditioning unit operates normally, the air conditioning unit does not need to be cleaned by scale, and the air conditioning unit is continuously controlled to operate normally, if I is larger than I0When the current value is increased under the condition that the heated water reaches the same temperature and an abnormal condition is generated, the situation is determined that the scale causes the heating function of the air-cooled heat pump hot water air conditioning unit to be reduced, and the prompt for cleaning the scale is sent out at the moment, so that an operator at the door can know the result, and further the situation is carried outAnd cleaning.
The above embodiments can illustrate the basic principles of the present invention, and based on this, the control method of the present invention may have some optimization and improvement, for example, in another possible embodiment, step S500 may be replaced by "when I > I ≧ I0+ICompensationWhen necessary, prompt the user to clean the scale, wherein ICompensation≧ 0 ″, since the air conditioner inevitably ages during use, which may result in the standard current I0The compensation value is increased, so that the single air conditioner can be optimally compensated by increasing the compensation value, and the judgment of the control method is more accurate.
In addition, in the above compensation scheme, the compensation may be related to the detection of fluctuation, especially in some regions with underdeveloped power grid, the current input is originally unstable, and the fluctuation is large at this time, which will bring continuous alarm and deteriorate the user experience, therefore, the setting ICompensationThe value of (A) is also particularly important, and the inventor has obtained a preferred embodiment as I through practical experimentsCompensationThe value of (d) is 0.5 ampere.
In another possible embodiment, step S600 may also be replaced with "when I ≦ I0And then, controlling the air conditioning unit to normally operate for delta t time, and returning to the step S100 ". The design has the advantages that the air conditioning unit can be detected once every delta t time, the condition of missing detection is avoided, and the delta t time can be flexibly set.
In another possible embodiment, the manner of sending the prompt for cleaning the scale in step S500 is various, and may be "controlling the alarm indicator to flash to prompt the user to clean the scale", or "controlling the display panel to display text or picture information of the scale to be cleaned to prompt the user to clean the scale", or the like.
In addition, in order to realize automation, the invention also provides a control method of the air-cooled heat pump hot water air conditioning unit, and the air conditioning unit comprises a water inlet and a water outletThe air conditioning unit further comprises a scale cleaning component, the structure of the air conditioning unit of the scheme is slightly different from that of the air conditioning unit of the technical scheme, the scale cleaning component is additionally arranged, and correspondingly, the control method is slightly different, and the difference is that when I is greater than I, the air conditioning unit of the scheme has the advantages that0When the scale cleaning component is used, the scale cleaning component can be controlled to start cleaning scale, and the prompt of whether to send out the scale cleaning can be selected at will. Of course, the scale cleaning means of the present invention are not developed, but the skilled person will be able to design flexibly depending on the actual structure, e.g. by scraping scale with a motorized scraper, etc.
In addition, the invention also provides an air-cooled heat pump hot water air conditioning unit, which is the air conditioning unit in the technical scheme, and the air conditioning unit also comprises a controller, and the controller can execute the control method in the technical scheme. That is, if the air conditioning unit does not have a scale cleaning component, a control method of only sending out a scale cleaning prompt is executed, and if the air conditioning unit does have a scale cleaning component, a control method of having a scale cleaning component or a control method of not having a scale cleaning component can be executed.
It should be noted that the above-mentioned embodiments are only used for illustrating the principle of the present invention, and are not intended to limit the protection scope of the present invention, and those skilled in the art can modify the above-mentioned structure so that the present invention can be applied to more specific application scenarios without departing from the principle of the present invention.
