S4, indoor controller are effective by the voltage of the temperature of indoor heat exchanger, the operation power of indoor fan and outdoor unit
Value is used as the first input variable, and is modeled according to operation power of first input variable to ptc heater to estimate
The operation power of ptc heater.
Specifically, due to influenceed during air-conditioning use PTC watt levels mainly include ambient temperature, magnitude of voltage and
Three principal elements such as air quantity, and these three factors have with evaporator temperature T2 (i.e. the temperature of indoor heat exchanger), input voltage
The operation power of valid value (i.e. the voltage effective value of outdoor unit) and indoor fan has direct contact.
Wherein, evaporator temperature T2 is the temperature near PTC, and the temperature T2 of evaporator is bigger, and caloric value needed for PTC is just
Smaller, i.e., T2 is bigger, and PTC operation power is smaller, conversely, PTC operation power is bigger, for example, T2 minimum value is set as that 10 take the photograph
Family name's degree, maximum are 80 degrees Celsius, enumerate the scope that T2 is likely to occur；The power P of indoor fanFANHave influence on dissipating for PTC
Heat, power is bigger, and radiating is better, and PTC will maintain temperature to send more heats, i.e. PFANBigger, PTC operation power is got over
Greatly, conversely, PTC operation power is smaller, for example, the power P of indoor fanFANMinimum value be taken as 2W, maximum is taken as 30W；Electricity
Pressure U directly affects PTC heating power, and U is bigger, and PTC operation power is bigger, conversely, PTC operation power is smaller, for example, PTC
The minimum value of input voltage U virtual values is 150V, maximum 280V, is defined above and below the voltage that China's power network is likely to occur
Limit.

Obtain the deviation compensation amount of the operation power of ptc heater, and the operation power for ptc heater that deviation compensation amount is added to
Correction is compensated with the operation power to ptc heater.
Specifically, there are some secondary causes for influenceing PTC power, such as：Indoor environment temperature T1, indoor environment humidity
Angle A of H and wind guide strip etc..Wherein, indoor environment temperature T1 can directly influence T2 size, so as to affect indirectly
PTC operation power, T1 is smaller, and T2 relative can also diminish, and can become big so as to PTC operation power, i.e., T1 is smaller, PTC operations
Power is bigger, conversely, PTC operation power is smaller；Indoor environment humidity H also influences whether PTC radiating, and humidity is bigger, air
In moisture it is more, by that can take away more heats when evaporator and PTC, therefore, H is bigger, and PTC operation power can become
Greatly, conversely, PTC operation power diminishes, certainly, the influence of humidity will not be so obvious；The angle A of wind guide strip has influence on air-conditioner wind
The structure of road outlet, during in standard an angle of 90 degrees, air channel air output is maximum, and radiating is best, 0 degree or during 180 degree, and wind guide strip is kept off
Air outlet has been lived, air channel air output is minimum, and radiating is worst, i.e. for A at 90 degree, PTC operation power is maximum with respect to other angles,
More deviate 90 degree, PTC operation power is smaller.
More specifically, secondary cause is also contemplated for into by we, the essence for improving PTC estimations by adding compensation to output
Degree, the mathematic(al) representation of the penalty function are as follows：ΔPPTC=ξ (um+1,…,un), wherein, um+1、…、unAs compensate school
Positive input sample value, Δ PPTCThe as compensation correction deviation of PTC power, ξ () are compensation correction functions.

Specifically, there are some secondary causes for influenceing PTC power, such as：Indoor environment temperature T1, indoor environment humidity
Angle A of H and wind guide strip etc..Wherein, indoor environment temperature T1 can directly influence T2 size, so as to affect indirectly
PTC operation power, T1 is smaller, and T2 relative can also diminish, and can become big so as to PTC operation power, i.e., T1 is smaller, PTC operations
Power is bigger, conversely, PTC operation power is smaller；Indoor environment humidity H also influences whether PTC radiating, and humidity is bigger, air
In moisture it is more, by that can take away more heats when evaporator and PTC, therefore, H is bigger, and PTC operation power can become
Greatly, conversely, PTC operation power diminishes, certainly, the influence of humidity will not be so obvious；The angle A of wind guide strip has influence on air-conditioner wind
The structure of road outlet, during in standard an angle of 90 degrees, air channel air output is maximum, and radiating is best, 0 degree or during 180 degree, and wind guide strip is kept off
