As a preferred embodiment, the condition for performing step S1 includes: when receiving CO removal sent by user2When the information instruction is given, step S1 is executed, wherein the user may send the information instruction through a remote controller, an air-conditioning panel, an intelligent terminal, or the like; of course, it is also possible to detect automatically by the air conditioner, i.e. when a CO is detected2When the concentration is equal to or greater than the preset concentration value, for example, reaches level3 and level4 in table 1, step S1 is performed.
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 the 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 an 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 closing of the intake valve 12, i.e. the opening of the exhaust passage 112, is effected, 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, for example, 10min, 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 desorption operation can also be performed on the CO at this time2The information such as the value and the duration detected by the module is displayed or broadcasted, for example, fed back to the user through an air conditioner display panel, a user terminal, and the like, and at this time, if an instruction for executing the desorption operation sent by the user is received, step S2 is started to be executed.
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 in detection environmentCO2And (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 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, and are described as level 1(C ≦ C1), level 2(C1 < C ≦ C2), level3(C2 < C ≦ C3), and level4(C > C3), where as a preferred embodiment, C1 ═ 450, C2 ═ 1000, and C3 ═ 2000 are shown in table 1:
TABLE 1
When the detection result is leave 1, the corresponding control mode selects mode one; when the detection result is leave 2, the corresponding control mode selects mode two; when the detection result is leave 3, the corresponding control mode selects mode three; when the detection result is leave 4, the corresponding control mode selects mode four; as a preferred embodiment, T1 ═ 50 ℃, T2 ═ 80 ℃, T1 ═ 20min, T2 ═ 17.5min, T3 ═ 15min, T4 ═ 10min, i.e. as shown in table 2:
TABLE 2
From a combination of tables 1 and 2, it can be seen that when the CO is present in an indoor environment2At very low concentrations, such as leve1, mode one is selected, i.e., the blower 14 is turned down (first speed), the heating temperature is turned down (T1), and the desorption time is longest (T1) due to CO2The concentration is lower, therefore, the control method of the invention is to CO2Slow desorption, i.e. prolonging CO2The desorption time mainly aims to achieve the effects of low energy consumption and low noise, so as to save electric energy and improve the user experience, and simultaneously, the indoor air environment can be further optimized; when CO is present in indoor environment2When the concentration is lower, such as leee 2, at this time, the mode two is selected, i.e. the rotating speed of the blower 14 is reduced (the first rotating speed), the heating temperature is increased (T2), and the desorption time is longer (T2), at this time, the effects of lower energy consumption and low noise can be achieved, and in addition, the desorption efficiency is improved compared with the mode one; when CO is present in indoor environment2When the concentration is higher, such as leee 3, at this moment, mode three is selected, namely the rotational speed of blower 14 is increased (the second rotational speed), the heating temperature is decreased (T1), the desorption time is shorter (T3), at this moment, the effect that the desorption efficiency is higher can be reached, so that remove CO more quickly2Working, and the energy consumption does not reach the highest value at the moment; when CO is present in indoor environment2When the concentration is very high, such as leee 4, the mode four is selected, the rotating speed of the blower 14 is increased (the second rotating speed), the heating temperature is increased (T2), and the desorption time is shortest (T4), so that the highest desorption efficiency is achieved, and the CO can be rapidly desorbed2Adsorption of (1), in summary, the air conditioner of the present invention depends on the CO in the current environment2And the concentration is selected, and the optimal combined mode of desorption efficiency, energy consumption and noise is selected, so that the optimal comprehensive use effect can be achieved on the premise of ensuring the indoor environment quality.
It should 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 of the inventive concept, which is derived from noiseFrom the perspective of sound and energy conservation, CO2The lower the concentration, the longer the cleaning time, and the more comfortable the solution for the user is sought in the reverse thinking process.
