As a supplementary description of the above embodiment, the embodiment of the present invention further provides a specific fresh air conditioner control method, as shown in fig. 2, where the tube temperature of the outdoor condenser is used as the outdoor temperature, and the CO2 concentration is used as the air quality parameter.
It is understood that the air conditioner is generally operated in a heating mode when the outdoor temperature is low. At this time, the outdoor temperature T is obtained through a thermal bulb arranged on the condenser of the outdoor unit, and then the outlet air temperature TC at the outlet of the indoor unit is obtained (the obtaining mode is not limited here). And controlling the running condition of each fan according to the outdoor temperature T and the air outlet temperature TC. It should be noted that the outer fan mentioned herein is a fan of the outdoor unit, and the inner main fan is a fan of the inner unit.
It should be noted that the compressor is in operation during the whole control process.
When outdoor temperature T is not more than first preset outdoor temperature T1, outer fan stops, gets into the mode of defrosting, and the cross valve is not electrified this moment, and the air conditioner gets into refrigeration operation mode, and the execution is interior quick-witted main air blower operation air-out mode, promptly: the fresh air fan stops, and the inner machine main fan operates.
When the outdoor temperature T is not less than the second preset outdoor temperature T2(T2 > T1) and the air outlet temperature TC is greater than the first preset air outlet temperature TC0 but not greater than the second preset air outlet temperature TC1(TC1 > TC0), the outer fan operates, the four-way valve is electrified, the air conditioner operates in a heating mode, and the fresh air fan operates in an air outlet mode, namely: the interior machine main air fan stops, and the new trend fan operation prevents the cold wind, guarantees the travelling comfort.
When the outdoor temperature T is not less than the second preset outdoor temperature T2(T2 > T1) and the temperature of the air outlet is greater than the second preset inlet air temperature TC1 but not greater than the third preset inlet air temperature TC2 (TC1 < TC2), the four-way valve is electrified, the normal heating running mode of the air conditioner executes the air outlet mode of the inner machine main fan and the fresh air fan running simultaneously, namely: the fresh air fan and the inner machine main fan are operated, the outer fan and the compressor are normally operated, the wind gear of the fresh air fan can be adjusted according to requirements (the color of a display plate of a CO2 sensor is shown in detail in a windshield for controlling the fresh air fan according to CO 2), and the purposes of improving indoor heating capacity and enhancing the heating effect of the air conditioner are achieved.
When the outdoor temperature T outer tube is not less than the second preset outdoor temperature T2(T2 > T1) and the temperature of the air outlet is more than the third preset outdoor temperature TC2, the four-way valve is electrified, the normal heating operation mode of the air conditioner also executes the air outlet mode of the simultaneous operation of the inner main fan and the fresh air fan, namely: the fresh air fan and the inner machine main fan are operated, but the outer fan is stopped; aims at preventing high temperature and improving comfort;
when the outdoor temperature T is not less than the second preset outdoor temperature T2(T2 is more than T1) and the temperature of the air outlet is not more than the first preset outdoor temperature TC0(TC0 is more than TC1 is more than TC2), the four-way valve is electrified, the air conditioner normally heats the running mode, and the air outlet mode that the inner machine main fan and the fresh air fan run simultaneously is also executed, namely: the fresh air fan and the inner machine main fan run, but the outer fan runs; the wind shield of the fresh air fan can be changed according to the requirement (the color of the display panel of the CO2 sensor), and the comfort is improved.
Wherein, the flow of changing the wind shield of the fresh air fan according to the color of the display panel of the CO2 sensor is shown in figure 3,
when the air conditioner is operated, the CO2 concentration sensor detects the indoor CO2 concentration, as a preferable implementation mode of the embodiment of the invention, the CO2 concentration sensor is arranged at the return air of the indoor unit, when the CO2 concentration sensor is smaller than a first preset value M1, the display panel is green, when the CO2 concentration is larger than or equal to a first preset value M1 and not larger than a second preset value M2 (wherein M1 is less than M2), the display panel displays yellow, and when the CO2 concentration is larger than a second preset value M2, the display panel displays red. When the display panel is green and yellow, namely when the concentration of CO2 is not more than M2, the wind shield of the fresh air fan is reduced; when the display panel is red, namely when the concentration of CO2 is greater than M2, the wind shield of the fresh air fan is increased.
It should be noted that displaying different colors by the display panel to show the magnitude relationship between the air quality parameter and the preset value is only an optional implementation manner of the embodiment of the present invention, and different sound indications may also be given by the buzzer.
It can be understood that the temperature of other positions of the outdoor unit can be used as the outdoor temperature, or a new temperature sensor can be directly arranged to directly acquire the outdoor temperature. Condenser tube temperatures are used herein as an example only.
Similarly, the air quality parameter of the present embodiment may also be PM2.5 and other parameters representing air quality. In the actual control process, if a plurality of air quality parameters are simultaneously controlled, the control is carried out according to the control standard of each air quality parameter. Illustratively, if the concentration of CO2 and the concentration of PM2.5 are simultaneously controlled, as long as any one of the concentration of CO2 and the concentration of PM2.5 reaches a preset value, the control is carried out according to a control mode corresponding to the air quality parameter reaching the preset value.
According to the specific fresh air equipment control method provided by the embodiment of the invention, the outdoor temperature is compared with the first preset outdoor temperature and the second preset outdoor temperature, and the air outlet temperature is compared with the first preset air outlet temperature, the second preset air outlet temperature and the third preset air outlet temperature; and whether the fresh air fan, the inner machine main fan and the outer fan operate is controlled according to the two comparison results, and whether the operation gear of the fresh air fan is controlled according to the air quality parameter is judged according to the two comparison results. When the operation gear of the fresh air fan is controlled according to the air quality parameter, the operation gear of the fresh air fan is controlled according to the comparison result of the air quality parameter and the first preset value and the second preset value. The reliability of the operation of the fresh air fan when the outdoor temperature is lower can be ensured, and the comfort of the indoor air can be ensured.
In one embodiment, the present invention provides a fresh air device control apparatus, as shown in fig. 4, including:
