step 110: entering a defrosting mode when the preset defrosting condition is met,
step 120: and a lower air outlet fan in the lower air outlet module of the air conditioner is controlled to rotate reversely to exhaust air outwards.
The lower air outlet module of the air conditioner is communicated with the outdoor unit of the air conditioner through a ventilation pipeline, and the end part of the ventilation pipeline is close to one side of the condenser or is opposite to the condenser.
After the air conditioner meets the preset defrosting condition, the defrosting mode is started, and in the execution process of the original defrosting mode, the lower air outlet fan in the lower air outlet module is controlled to run reversely and exhaust air outwards. The conventional air conditioner outdoor unit can be frosted when the air conditioner operates in a heating mode, the original defrosting mode can be started at regular time or can be started according to time-temperature difference control or can be started according to condensing temperature, and the lower air outlet fan is controlled to exhaust air outwards while the original defrosting mode is started, so that the direction of the lower air outlet fan is reversed when the air is exhausted outwards. The lower air outlet fan runs reversely, so that indoor hot air is discharged to the condenser through the ventilation pipeline, defrosting and deicing of the outdoor unit of the air conditioner are accelerated, and the defrosting and deicing time is shortened. Meanwhile, because the indoor hot air is pumped out by the lower air outlet fan, the indoor air pressure is lower, a negative pressure area is formed, and the indoor air is favorably updated.
According to the defrosting method for the outdoor unit of the air conditioner, the original defrosting mode is executed, meanwhile, the lower air outlet module discharges indoor hot air outwards, and the hot air is discharged to the condenser through the ventilation pipeline, so that the defrosting and deicing time is shortened. The defrosting method of the outdoor unit of the air conditioner provided by the invention has the advantages that a negative pressure area is formed indoors during defrosting so that outdoor air can enter indoors and the indoor air can be updated conveniently.
Fig. 2 is a second flowchart of the defrosting control method for the indoor unit of the air conditioner provided by the invention. On the basis of the foregoing embodiment, as shown in fig. 2, the defrosting control method for an indoor unit of an air conditioner according to an embodiment of the present invention further includes:
step 130: and when the defrosting mode is started, the electric heating operation in the lower air outlet module of the air conditioner is also controlled. Also when the original defrosting mode of air conditioner operation, the electrical heating in the lower air-out module all moves with lower air-out fan, carries out the secondary heating to indoor hot-air, further promotes the air temperature who carries to the condenser, and the efficiency of defrosting and deicing accelerates.
According to the defrosting control method for the indoor unit of the air conditioner, provided by the embodiment of the invention, the electric heating in the lower air outlet module heats the hot air in the room, so that the temperature of the air discharged by the ventilation pipeline is further increased, the defrosting and deicing efficiency is further increased, and the defrosting and deicing time is shortened.

For example, when the temperature of the coil pipe is lower than a first preset temperature, the lower air outlet fan runs reversely at a high speed; when the temperature of the coil pipe is greater than or equal to a first preset temperature and less than a second preset temperature, the lower air outlet fan reversely runs at a medium speed; and when the temperature of the coil pipe is greater than or equal to a second preset temperature, the lower air outlet fan runs at a low speed in the reverse direction. It will be appreciated that the first predetermined temperature is less than the second predetermined temperature.
For another example, when the temperature of the coil pipe is lower than the first preset temperature, the lower air outlet fan runs reversely at a high speed, and the electric heating runs at a high power. When the temperature of the coil pipe is greater than or equal to a first preset temperature and less than a second preset temperature, the lower air outlet fan runs reversely at a medium speed, and the electric heating power is reduced; when the temperature of the coil pipe is larger than or equal to the second preset temperature, the lower air outlet fan runs reversely at a low speed, the electric heating is stopped, and the frost is dissolved by means of the waste heat. It will be appreciated that the first predetermined temperature is less than the second predetermined temperature.
Of course, the rotating speed of the air outlet fan and/or the working efficiency of the electric heating can also be controlled according to the running time of the defrosting mode. For example, the operation time of the defrosting mode can be divided into three stages, and at the initial stage, the rotating speed of the air outlet fan and/or the working efficiency of electric heating are controlled. And in the second time stage, the rotating speed of the lower air outlet fan is adjusted downwards and/or the working efficiency of electric heating is adjusted downwards. And in the third time stage, the rotating speed of the lower air outlet fan and/or the working efficiency of electric heating are/is further adjusted downwards.
On the basis of any one of the above embodiments, when the defrosting mode operation is finished, the operation of the lower air outlet fan and the electric heating is controlled according to the lower temperature and the upper temperature of the indoor space. The lower air outlet module of the air conditioner and the main air outlet module of the air conditioner operate independently respectively, if the difference value between the lower temperature and the upper temperature in the indoor space is more than or equal to 2 degrees, the lower air outlet fan and the electric heating operation in the lower air outlet module are controlled, the lower air outlet module discharges hot air, and the air temperature of the indoor lower part is compensated. And if the difference value between the lower temperature and the upper temperature in the indoor air is less than 2 degrees, the lower air outlet fan and the electric heating stop running.
The defrosting method for the outdoor unit of the air conditioner provided by the embodiment of the invention comprises the following steps:

On the basis, the electric heating operation in the lower air outlet module is further controlled to heat the hot air in the chamber, the temperature of the air exhausted by the ventilation pipeline is increased, and the defrosting and deicing time is effectively shortened.
The operation efficiency of the electric heating and the rotating speed of the lower air outlet fan are controlled according to the temperature of the coil of the outdoor unit of the air conditioner, and the operation efficiency of the electric heating and the rotating speed of the lower air outlet fan can be divided into three control gears or two control gears.
And after defrosting is finished, controlling the working state of the lower air outlet module according to the difference value between the upper temperature and the lower temperature of the indoor space. When the temperature difference is more than or equal to 2 degrees, the lower air outlet module starts electric heating to exhaust hot air to the indoor space, the lower temperature of the indoor space is adjusted, and the temperature difference between the upper part and the lower part in the indoor space is reduced. When the temperature difference is less than 2 degrees, the electric heating of the lower air outlet module is turned off to save energy.
According to the defrosting method for the air conditioner outdoor unit, the lower air outlet fan in the lower air outlet module of the air conditioner is reversely operated to convey hot air outwards, so that indoor air can be promoted to be updated while defrosting and deicing are carried out, a good adjusting effect is achieved on air conditioning in a heating mode, and the use experience of a user is improved.
