[0002] After the air conditioner is used for a long time, due to the blockage of the filter screen and the aging of the indoor wind wheel, the attenuation of the air volume and wind speed will occur, which will affect the heating effect of the air conditioner
[0003] Even if the air conditioner has not been used for a long time, due to the different conditions such as installation and use environment, there will be a large gap between the return air temperature of the air conditioner and the temperature in the room where the air conditioner is used. Uneven temperature distribution in the use environment will affect the heating effect

The invention discloses a method for controlling an indoor fan rotating speed of an air conditioner under a heating mode. The controlling method comprises a first step of detecting the indoor environment temperature T1 and the evaporator coil temperature T2 in the air conditioner running process; a second step of comparing the indoor environment temperature T1 with a first predetermined threshold T1s and comparing the evaporator coil temperature T2 with a second predetermined threshold T2s; a third step of controlling an indoor fan to be improved to a second rotating speed Nj from a first rotating speed Ni to run when in the second step detecting that T1 is larger than T1s and T2 is larger than T2s; returning to the second step when in the second step detecting that T1 is no larger than T1s and T2 is no larger than T2s; a fourth step of comparing the evaporator coil temperature T2 with a third predetermined threshold T2x; a fifth step of entering the second step when T2 is smaller than T2x, and returning to the fourth step when T2 is no smaller than T2x. By utilizing the controlling method, the more comfortable environment can be provided for users, service lives of components are prolonged, and the energy saving effect of the air conditioner is improved.
Description
technical field [0001] The invention relates to the field of refrigeration equipment, in particular to a method for controlling the rotational speed of an indoor fan of an air conditioner in a heating mode. Background technique [0002] After the air conditioner is used for a long time, due to the blockage of the filter screen and the aging of the indoor wind wheel, the attenuation of the air volume and wind speed will occur, which will affect the heating effect of the air conditioner. [0003] Even if the air conditioner has not been used for a long time, due to the different conditions such as installation and use environment, there will be a large gap between the return air temperature of the air conditioner and the temperature in the room where the air conditioner is used. The uneven temperature distribution in the use environment will affect the heating effect. Contents of the invention [0004] The present invention aims to solve at least one of the technical proble...
