Furthermore, in general, the user is not aware of the indoor CO2Concentration, CO detected by display of the invention2Concentration information to the user so that the user knows the indoor CO2Concentration, wherein the display mode includes various forms, for example, through the forms of air conditioner panel, remote controller display screen, intelligent terminal or voice, of course, can carry out CO according to preset frequency2The concentration information can be displayed, and CO can be updated and displayed in real time2The concentration information is given to the user for better perception by the user.
Wherein, the air conditioner indoor unit 1 of the invention is integrated with CO at the same time2A detection module capable of detecting CO in the environment2Concentration, as a preferred embodiment, of CO2The detection module is arranged at an indoor air inlet (an air inlet for enabling air to exchange heat in the air conditioner) of the air conditioner, indoor air enters the air conditioner through the air inlet and passes through CO2The detection module detects the indoor air quality and transmits the detection result to the air conditioner in an electric signal.
Step S2: the exhaust valve 13 is opened, the intake valve 12 is closed, and the foul air adsorption and release unit 15 is controlled to release foul air or foul substances.
When CO is required2By opening the exhaust valve 13, the intake valve 12 is closed, i.e. the exhaust passage 112 is opened, and CO is carried out by the blower 142So as to ensure the repeated cyclic utilization of the foul gas adsorption and release unit 15.
The conditions for executing step S2 include: detected CO2When the concentration is no longer reduced for a set period of time, e.g. CO2The value detected by the detection module is within a certain fixed range and does not decrease, and the preset time lasts for 10min, for example, which indicates that the foul air adsorption and release unit 15 has reached the saturation state, at this time, the air conditioner automatically performs the desorption operation, and certainly, the CO at this time can also be desorbed2Value detected by module and holdThe information such as the time duration is displayed or broadcasted, for example, by an air conditioner display panel, a user terminal, or the like, and when receiving a desorption execution instruction from the user, the processing starts to execute step S2.
Step S2 of the present invention further specifically includes the following preferred technical solutions:
since the foul gas adsorption and release unit 15 specifically includes the solid amine adsorption block and the heating module, the solid amine adsorption block is heated by controlling the heating module to release CO adsorbed by the solid amine2。
Adsorption material solid amine adsorption block for adsorbing CO2The amount of the solid amine adsorption block is related to the volume of the material, the solid amine adsorption block can reach a saturated state after reaching a certain degree, and the heating module is controlled to heat after the solid amine adsorption block reaches the saturated state so as to realize CO2The desorption temperature is between 50 and 80 ℃ in the normal condition, the desorption rate is faster when the temperature is higher in the range, therefore, the CO can be controlled by controlling the temperature of the heating module2The purpose of the desorption rate of.
As shown in fig. 5, specifically, the above preferred technical solution of step S2 of the present invention further specifically includes the following steps:
step S21, control CO2Detection module detects CO in environment2And (4) concentration.
Step S22: based on detected CO in the environment2The blower 14 is controlled to select different rotation speeds, and the heating module is controlled to select different heating temperatures and desorption times.
Step S221: when C is less than or equal to C1, the blower 14 operates at the first rotation speed, the heating temperature is T1, and the desorption time is T1.
Step S222: when C is more than C1 and less than or equal to C2, the blower 14 operates at the first rotation speed, the heating temperature is T2, and the desorption time is T2.
Step S223: when C is more than C2 and less than or equal to C3, the air blower 14 operates at the second rotating speed, the heating temperature is T1, and the desorption time is T3.
Step S224: when C is more than C3, the blower 14 is operated at the second rotation speed, the heating temperature is T2, and the desorption time is T4.
Wherein C is CO in the environment2The concentrations of C1, C2 and C3 are preset CO2The concentration is T1 < T2, T1 > T2 > T3 > T4, and the first rotating speed is less than the second rotating speed.
The invention converts CO into2The detection results of the detection module are divided into 4 grades, which are described as leve1(C ≦ C1), leve2(C1 < C ≦ C2), level3(C2 < C ≦ C3), and level4(C > C3), as a preferred embodiment, C1 ═ 450, C2 ═ 1000, and C3 ═ 2000, that is, as shown in table 1:

It is to be noted that CO is suggested to those skilled in the art2In relation to desorption time, the conventional control method is CO2The lower the concentration, the shorter the cleaning time, however, the invention is just the opposite, from the point of view of noise and energy saving, the CO2The lower the concentration, the longer the cleaning time, and the more comfortable the solution for the user is in the process of reverse thinking.
With continued reference to fig. 4, after step S2, the method further includes the following steps:
step S3: the blower 14 is turned off to control CO2Detection module detects CO in environment2Concentration; the detected CO is2And converting the concentration information into environment grade information and displaying the environment grade information to a user.
When CO is not required2When the adsorption is working, e.g. when CO is detected2At concentrations < preset concentration values, e.g. when good grades of leve1 and leve2 are reached, or when CO is present2When the adsorption operation is over a preset time, the operation is automaticThe blower 14 is turned off and the environment is vented to CO2Detecting the concentration, and detecting the detected CO2The concentration information is converted into environment grade information to be displayed to a user, or the CO is displayed at the same time2Concentration information and CO2And displaying the information of the operation time of the adsorption work to a user.
