Based on the air-conditioner that above-described embodiment provides, the control method of the auxiliary heat of electricity of above-mentioned air-conditioner comprises the steps:
S1: when air-conditioner powers on operation, detected the drag overall of air conditioner room unit inside and outside by wind pressure detection device.
Wherein, the drag overall of described air conditioner room unit inside and outside comprises: the pressure of the blower fan of described air-conditioner and the pressure sum of filter.
S2: described drag overall is compared with the first preset pressure value and the second preset pressure value respectively.
S3: if described drag overall is less than described first preset pressure value or is greater than described second preset pressure value, then cut off the power supply of the auxiliary heat of electricity of described air-conditioner;
Wherein, described first preset pressure value is less than or equal to described second preset pressure value.
It should be noted that, described first preset pressure value can equal described second preset pressure value, then when both are equal, drag overall is then compared with the first preset pressure value (or second preset pressure value), if drag overall is not equal to the first preset pressure value (or second preset pressure value), then cut off the power supply of the auxiliary heat of electricity of air-conditioner.
Understandably, if drag overall is more than or equal to described first preset pressure value and be less than or equal to described second preset pressure value, then do not need the power supply of the auxiliary heat of electricity cutting off described air-conditioner, air-conditioner runs according to setting.
For example, above-mentioned wind pressure detection device can be leeway switch, by the both sides of leeway switch-linear hybrid in blower fan and filter, utilizes the pressure reduction of two pipelines to send electric signal, when the pressure reduction at two ends raises or reduces and exceed setting value, then can control the power supply cutting off electric auxiliary heat in time.

Specifically, if the static pressure of airduct and described design static pressure inconsistent, then according to the resistance of described unit inside and the static pressure sum F ' of described airduct, readjust the first preset pressure value and the second preset pressure value.Particularly, setting the first preset pressure value according to F ' is F ' (1-Δ F '), and to set the second preset pressure value be F ' (1+ Δ F '), and wherein, Δ F ' is surplus, and Δ F '≤1.
For example, if the design static pressure sum of the resistance of unit inside and unit is 250Pa, and the static pressure sum of the resistance of unit inside and actual institute air duct is 200Pa, and Δ F ' is 20%, then readjusting the first preset pressure value is 200 × (1-20%)=160Pa, and the second preset pressure value is 250 × (1+20%)=300Pa.Then correspondingly, if the drag overall of air conditioner room unit inside and outside is less than 200Pa or is greater than 300Pa, then cut off the power supply of the auxiliary heat of air-conditioner electricity.
Specifically, step S3 specifically comprises the steps:
S31: if described drag overall is less than described first preset pressure value or is greater than described second preset pressure value, then judge that the auxiliary heat of the electricity of described air-conditioner is current and whether open;
S32: if the current unlatching of the auxiliary heat of the electricity of described air-conditioner, then cut off the power supply of the auxiliary heat of described electricity, and send alarm signal;
S33: do not open if the auxiliary heat of the electricity of described air-conditioning is current, then forbid that the next time of the auxiliary heat of described electricity opens, and send alarm signal.
Specifically, when drag overall is less than described first preset pressure value or is greater than described second preset pressure value, show that blower fan has damaged or filter blocks, if the then current unlatching of electric auxiliary heat, then close the power supply of the auxiliary heat of described electricity immediately, avoid the calm dry combustion method of electric auxiliary heat, and if electric auxiliary heat is current does not open, also should forbid when the auxiliary heat of electricity next time is opened, because blower fan is still in damage or filter is still in blocked state.
