[ first embodiment ] A method for manufacturing a semiconductor device
Based on the problem, the embodiment of the invention provides an air conditioner control method. Referring to fig. 1-2, which are control flow charts of an air conditioner control method, the air conditioner control method includes the steps of:
step S1: starting a self-cleaning function of the air conditioner, wherein the self-cleaning function comprises a water washing function and/or a sterilization function;
step S2: and if the water washing function is started, selecting the water washing time ts to carry out the water washing operation.
Step S3: if the sterilization function is started, the air conditioner acquires bacterial colony type information, and sets corresponding sterilization time t according to the bacterial colony type information so as to perform sterilization operation.
Step S4: the air conditioner performs the washing operation and/or the sterilizing operation.
In a specific embodiment, in step S1, it should be noted that, after the self-cleaning function is turned on, the user selects whether to turn on the water washing function and whether to turn on the sterilization function in turn, and the selection process may preferentially select the water washing function and may preferentially select the sterilization function. Accordingly, the air conditioner can perform the washing function or the sterilization function, or perform the washing function and the sterilization function simultaneously.
The user can start the self-cleaning function of the air conditioner through remote control or APP, and selects the water cleaning function and/or the sterilization function on the remote control or APP.
In a specific embodiment, it should be noted that in the step S2, the washing time ts is, for example, 10min to 15min, and the user can adjust the washing time ts between 10min to 15min through remote control or APP, for example, the washing time ts is set to 11min, 12min, 13min, 14min, and the like, which is not limited herein.
In a specific embodiment, it should be noted that, in the step S3, the colony type information includes, for example, p.diphtheriae, streptococcus pneumoniae, escherichia coli, influenza virus, and new coronavirus, but the colony type information may also include other common bacterial species, which is not limited herein.
Further, bacterial colony information accessible user's autonomous selection, remote control or APP list the bacterial species that contains in the bacterial colony kind information, the user selection arbitrary one in the bacterial species makes the air conditioner can adopt specific sterilization time t to the bacterial species, makes the evaporimeter coil maintain sterilization time t is in order to reach the bactericidal effect of evaporimeter coil.
Still further, the different colony species information has corresponding target temperatures T, respectively. Preferably, after the user selects any one of the strains, the air conditioner may also adopt a specific sterilization temperature for the strains. Namely, the sterilization operation includes, for example: in the heating mode, the evaporator coil temperature Tp is raised to the target temperature T, and the sterilization time T is maintained. Wherein the target temperature T is the corresponding sterilization temperature.
Specifically, see table 1 below:
TABLE 1
| Species of | Target temperature T (. degree. C.) | Time to kill t (min) |
| Bordetella diphtheriae | ≥50 | ≥10 |
| Streptococcus pneumoniae | ≥56 | ≥7 |
| Escherichia coli | ≥56 | ≥1 |
| Influenza virus | ≥56 | ≥30 |
| Novel coronavirus | ≥56 | ≥30 |
Preferably, bacteria or viruses having the target temperature T and the sterilization time T close to each other may be combined when selecting the colony type information. For example, the same mode can be adopted for removing the influenza virus and the new coronavirus, namely the target temperature T is more than or equal to 56 ℃, and the sterilization time T is more than or equal to 30 min.
Preferably, since the influenza virus and the new coronavirus are more thermostable than the p.diphtheriae, the streptococcus pneumoniae, and the escherichia coli, that is, the influenza virus and the new coronavirus can be removed simultaneously in a mode in which the p.diphtheriae, the streptococcus pneumoniae, and the escherichia coli can be removed, the air conditioner can prompt the user that the mode can simultaneously remove the p.diphtheriae, the streptococcus pneumoniae, and the escherichia coli when the user selects the influenza virus or the new coronavirus.
And specific target temperature T and sterilization time T are adopted for different colony species information, so that heat-resistant strains can be effectively killed, and energy can be saved when thermolabile strains are killed.
In a specific embodiment, the step S4 includes, for example:
step S41: the air conditioner performs the washing operation.
Step S42: the air conditioner performs the sterilization operation.
It should be noted that, when the user selects to execute the water washing function and the sterilization function simultaneously, the air conditioner executes the water washing function first and then performs the sterilization function, that is, executes the step S41 and the step S42 in sequence; when the user does not select to perform the water washing function, skipping the step S42; when the user does not select to perform the sterilization function, the step S41 is skipped.
Preferably, in the step S41, the water washing operation includes, for example: the air conditioner is in a cooling mode such that cold air is generated in the evaporator coil and dew is condensed on the evaporator, thereby flushing the evaporator coil with dew.
Preferably, in the step S42, the sterilization operation includes: in the heating mode, the evaporator coil temperature Tp is raised to the target temperature T, and the sterilization time T is maintained. On this basis, the sterilization operation further includes, for example: it is determined whether or not the indoor ambient temperature Th satisfies the initial operating frequency control condition, that is, the initial operating frequency F0 of the compressor is set according to the indoor ambient temperature Th. When the indoor ambient temperature Th is high, the compressor is liable to overshoot, which causes the evaporator coil temperature Tp to exceed the target temperature T, and the system is in failure, so that the initial operating frequency F0 of the compressor needs to be limited.
Further, the initial operating frequency control condition includes, for example: th is more than or equal to Ta, and the initial running frequency F0 is F1; ta is more than Th and is more than or equal to Tb, and the initial operation frequency F0 is F2; th < Tb, and F3 as the initial operating frequency F0. Ta and Tb are temperature set values of the initial operation frequency control condition, Ta is 27-33 ℃, Tb is 17-23 ℃, for example Ta is 30 ℃, Tb is 20 ℃, and under the temperature set values, when the temperature in summer is high, the air conditioner can actively adjust the initial operation frequency F0 of the compressor by executing a sterilization function, so that the temperature of the compressor is prevented from being too high when the weather is hot.
Still further, F1 < F2 < F3 makes the air conditioner can further limit the frequency of the compressor when the indoor environment temperature Th is higher, and ensures the stable work of the compressor. Wherein the value range of F1 is 50-60 Hz; the value range of F2 is 60-70 Hz; the value of F3 is 70-80 Hz, for example, F1 ═ 55Hz, F2 ═ 65Hz, and F3 ═ 75 Hz.
Preferably, the sterilization operation further includes, for example: the compressor operates for T0 time at an initial operating frequency F0, the current evaporator coil temperature T0 is detected, whether the current evaporator coil temperature T0 meets the compressor operating frequency adjusting condition or not is judged, and if the current evaporator coil temperature T0 meets the compressor operating frequency adjusting condition, the compressor operating frequency F is adjusted. The time t0 is, for example, 2 min.
Further, Δ T ═ T0-T; the compressor operation frequency adjustment conditions include, for example: if delta T is less than or equal to a, the running frequency F of the compressor is increased at the speed of v 1; if a <. DELTA.T.ltoreq.b, the compressor operating frequency F rises at a speed v 2; if b <. DELTA.T.ltoreq.c, the compressor operating frequency F rises at a speed v 3; if c is less than delta T and less than or equal to d, keeping the running frequency F of the compressor unchanged; if d <. DELTA.T.ltoreq.e, the compressor operating frequency F is reduced at a speed of v 4; if e <. DELTA.T, the compressor operating frequency F drops at a speed of v 5. The variable frequency speed set by v1, v2, v3, v4 and v5 for the operating frequency adjusting condition of the compressor is v1 > v2 > v3, and v4 < v5, namely, the larger the difference between the current evaporator coil temperature T0 and the target temperature T is, the faster the variable frequency speed is adjusted to the target temperature T, so that the current evaporator coil temperature T0 is prevented from being lower than the target temperature T for a long time to cause poor sterilization effect, or the current evaporator coil temperature T0 is higher than the target temperature T for a long time to cause overhigh system pressure and cause failure.
For example, a is-5 deg.C, b is-2 deg.C, c is 0 deg.C, d is 3 deg.C, and e is 5 deg.C. If delta T is less than or equal to-5, the running frequency F of the compressor rises to 8Hz every 90 s; if delta T is less than-5 and less than or equal to-2, the running frequency F of the compressor is increased by 4Hz every 90 s; if delta T is more than-2 and less than or equal to 0, the running frequency F of the compressor is increased by 2Hz every 90 s; if delta T is more than 0 and less than or equal to 3, maintaining the operation frequency F of the compressor unchanged; if delta T is more than 3 and less than or equal to 5, reducing the running frequency F of the compressor by 4Hz every 90 s; if 5 <. DELTA.T, the compressor operating frequency F drops by 8Hz every 90 s.
