Further, in the high wet interval, the dehumidification mode is opened to the unit, if the air-out temperature is less than return air temperature (room temperature), then indoor temperature can descend, opens electrical heating this moment and heats the air-out temperature. The temperature difference value of the air return temperature minus the air outlet temperature is the power number (unit is W) of the electric heating power which is increased compared with the previous period, and meanwhile, the pipe temperature in the evaporator is used for correcting, the lower the pipe temperature is, the larger the cooling degree of the air return temperature through the evaporator is, the lower the air outlet temperature is, the larger the correction coefficient value is, the larger the heating power of the electric heating device 500 is, the air outlet is heated, and the indoor cooling-free and dehumidifying effects are achieved.
Further, if the electric heating still fails to make the outlet air temperature = the return air temperature within a certain time, the electric heating enters a special adjusting mode, and directly enters the maximum power heating outlet air temperature. If the system recognizes that the air outlet temperature is greater than the air return temperature for a certain time, the electric heating is closed, and the dynamic balance between the air outlet temperature and the air return temperature is kept.
Preferably, after opening a period in succession at electric heater unit 500 through the setting, and the air-out temperature is less than return air temperature, then control electric heating power and improve to maximum power, make the air conditioner can reach the effect of not cooling down the dehumidification sooner, and because the air-out temperature that all does not reach for a period is less than return air temperature, it is abominable to explain current environment, through raising power to the biggest, make the air conditioner can guarantee the increase of the fastest degree of air-out temperature, guarantee that the user can not feel cold when using again, improve user's use and experience. Through setting up the big or small relation of the difference and the second setting value of comparison air-out temperature and return air temperature, when air-out temperature and return air temperature difference were greater than the second setting value, it was good promptly to show current environment, need not heat again, had saved the consumption of the energy, kept the balance of air-out temperature and return air temperature simultaneously, made the air-out temperature of air conditioner be in the most suitable state, made user experience feel better.
Specifically, when the indoor relative humidity falls into a second interval, determining that the target dehumidification mode of the air conditioner is a second mode; wherein the second mode comprises: and judging whether the air outlet temperature is less than the air return temperature within the third target time, if so, starting the electric heating device 500, and increasing the power of the electric heating device 500 according to the difference between the air return temperature and the air outlet temperature of the air conditioner.
Specifically, the second interval is an artificially set interval and can be adjusted according to actual conditions, for example, the indoor relative humidity is greater than 45% and less than or equal to RH 65%, the indoor humidity state is normal at this time, the third target time is also an artificially set value, the value is 10s, that is, when T2 is greater than T1 and lasts for 10s, the electric heating is automatically turned on to heat the outlet air, and the initial power of the electric heating is 0W.
Further, the power of the electric heating apparatus 500 is adjusted according to the formula W '= W1' + S2 (T1 '-T2'); w 'is the power of the electric heating device 500 in the next cycle, W1' is the power of the electric heating device 500 in the previous cycle, T1 'is the return air temperature in the previous cycle, T2' is the outlet air temperature in the previous cycle, S2 is a constant greater than zero, and the power of the electric heating device 500 is periodically adjusted. When the indoor relative humidity is in a first range, the value of the constant S2 is as follows; when the indoor relative humidity is in the second range, the constant S2 is S2' and S2' > S2 '.
Specifically, where the periodicity is also set to 5s for example, s2 is a correction coefficient of indoor relative humidity, the first range and the second range are also human defined values, and may be adjusted according to actual situations, where: when the first range is 55 percent to RH and is less than or equal to 65 percent, the correction coefficient S2' is 0.5n; when the RH is more than 45% and less than or equal to 55% in the second range, the correction coefficient S2' is 0.25n; n is more than or equal to 1 and less than 1.5.
Further, in the second interval, when T2-T1 is more than or equal to Q and lasts for 10min, the electric heating power is immediately reduced to 0W, and the rest is regulated in a normal mode, wherein Q is more than 0.
Preferably, human perception is more comfortable in the normal humidity interval, and the air-out temperature is slightly less than return air temperature (room temperature), and the human body can not feel too "shady and cold", if satisfy the electrical heating start condition at this moment and correct with relative humidity RH, makes electrical heating start power keep a relatively low value, not only satisfies the demand but also energy-conservation.
Specifically, when the indoor relative humidity falls into the third interval, determining that the target dehumidification mode of the air conditioner is the third mode; wherein the third mode comprises: adjusting the rotating speed of an inner fan of the air conditioner to be reduced to the lowest rotating speed; the compressor frequency of the air conditioner is controlled to decrease as the indoor relative humidity decreases.
Specifically, the third interval is also a set value, specifically, the indoor relative humidity RH is less than or equal to 45%, at this time, because the humidity is low, the electric heating is not started, and the rotation speed of the inner fan is automatically adjusted to a low wind gear (the wind gear of the inner fan is strong, high, medium and low); meanwhile, in the relative humidity interval, every 30min, if the relative humidity is reduced by more than 10% compared with the previous time, the frequency of the compressor is reduced by 5% compared with the previous time (until the frequency reduction condition is triggered). Until the interval is exited.
Specifically, when the indoor relative humidity is less than or equal to 45%, the indoor air is in a low-humidity environment, the humidity is low, the air is abnormally dry, a human body feels uncomfortable, and the dehumidification amount needs to be reduced at the moment. If the indoor relative humidity is reduced by more than 10% within 30min, the dehumidification capacity is high, and at the moment, the frequency of the press needs to be reduced, the refrigerant circulation flow is reduced, the heat exchange capacity of an inner machine evaporator is reduced, the temperature of the pipe is increased, and the dehumidification capacity is further reduced.
Specifically, for example, the unit starts a dehumidification mode to operate, and automatically identifies system parameters, namely indoor relative humidity and inner ring temperature, namely room temperature. The system recognizes that the room temperature Tai =23 ℃ is less than 26 ℃ and the relative humidity RH =70% > 65%, enters a non-cooling dehumidification mode, and starts electrical heating.
Further, the system detects return air temperature T1=23 ℃, T2=15 ℃, tem =15 ℃, K1=5, K2=15, m =1. The heating power of the electric heating in the first period is as follows: w = W1+ S1 (T1-T2) =0+1 × (23 ℃ -15 ℃) =8W. One cycle of regulation every 5s, the latter cycle being regulated in the same manner as above.
Further, when the system detects that T2-T1=5 during the operation of the air conditioner, namely the value of Q is 5, and the operation lasts for 10min, the electric heating power is immediately reduced to 0W until the next starting condition is met.
Preferably, the outlet air of the dehumidification mode is heated by electric heating of the air outlet 400 of the inner machine, so that the indoor temperature is not reduced, and the effect of not reducing the temperature and dehumidifying is achieved. The heating power of the electric heating device 500 is calculated and adjusted every 5s period according to the temperature difference between the real-time return air and the real-time outlet air, so that the condition that the indoor temperature rise exceeds the requirement due to long-time operation of the same power is avoided, and meanwhile, the heating power can quickly meet the requirement, so that the indoor temperature and humidity balance is achieved.
