if outdoor environment temperature not higher than the leaving air temp of the 5th temperature value and inner blower 6 not higher than the 8th temperature value, controller 1 control compressor 4 and inner blower 6 are out of service, the 5th temperature value is low temperature value, for example 0 ℃ of left and right or lower subzero 8 ℃ of left and right, this moment, compressor 4 was to hang down load running, easily band liquid operation, take the 5th temperature value as 8 subzero 8 ℃, the 6th temperature value is 12 ℃ of calculating, this moment, supply air temperature difference was 20 ℃, the leaving air temp of inner blower 6 is 12 ℃, the leaving air temp of inner blower 6 is very likely lower than room temperature so, room temperature can reduce so, heating effect can't reach, controller 1 should control compressor 4 and inner blower 6 is out of service, why also to the leaving air temp of inner blower 6 be judged herein, because the air conditioner fresh air machine is certain to the adjustable range of temperature, when outdoor environment temperature is ultralow, the leaving air temp of inner blower may be higher than indoor temperature, also likely lower than indoor temperature, possibility with the latter occupies large, therefore, carrying out dual restriction is conducive to control more accurately,
Wherein, the 4th temperature value is greater than the 8th temperature value, and the 8th temperature value is greater than the 5th temperature value, and according to different outdoor environment temperatures and the leaving air temp of inner blower 6, controller 1 is controlled the switch of compressor 4 and controlled the switch of inner blower 6.
To sum up, the control method of the air conditioner fresh air machine that the embodiment of the present invention provides can be controlled according to outdoor environment temperature the operation of compressor 4 and inner blower 6, and while preventing from heating, indoor heat runs off, and while preventing from freezing, indoor cold runs off, extend the service life of compressor 4, reduce energy consumption.
Wherein, the first temperature value can be 40 ℃, and the second temperature value can be 50 ℃, and the 3rd temperature value can be 18 ℃, and the 6th temperature value can be 30 ℃.Certainly can also change and adjust according to the different temperatures of different geographical.
Wherein, the 4th temperature value can be 26 ℃, and the 5th temperature can be subzero 8 ℃, and the 8th temperature value can be 12 ℃.Certainly can also change and adjust according to the different temperatures of different geographical.
Wherein, the 4th temperature value is 20 ℃, and the 5th temperature is 0 ℃, and the 8th temperature value is 12 ℃.Certainly can also change and adjust according to the different temperatures of different geographical.
Wherein, when air conditioner fresh air mechanism is hot, if the leaving air temp of inner blower 6 not higher than the 7th temperature value, controller 1 is controlled the low wind speed operation of inner blower 6.Due to when the actual motion, the leaving air temp of inner blower 6 determining actually to be refrigeration or to heat, therefore, when heating, the first situation:, if the leaving air temp of inner blower 6, lower than certain value, can be controlled inner blower 6 by controller 1 and be in low wind speed, avoid low temperature cold wind to enter indoor; The second situation: when the leaving air temp continuation reduction of inner blower 6 is even lower, can be out of service by controller 1 control compressor 4 and inner blower 6; When practical operation, the 8th temperature value meets the second situation, the 8th temperature value is lower than the 7th temperature value so, the 7th temperature value belongs to the first situation, and the 7th temperature value belongs to the lower temperature value, and inner blower 6 may be lower than indoor temperature to indoor leaving air temp, at this moment, controller 1 is controlled the low wind speed operation of inner blower 6, avoids causing because the wind speed of inner blower 6 is too high not heating fully just to send into indoor, avoids too much cold wind to enter the indoor indoor temperature that causes and raises.
