no. 1 example

[0070] refer to figure 2 , the first embodiment of the air conditioner defrosting control method of the present invention is proposed, and the air conditioner defrosting control method includes:

[0071] Step S10, after the air conditioner enters the defrosting mode, the initial defrosting frequency of the air conditioner is obtained.

[0072] Step S20, controlling the air conditioner to defrost according to the initial defrosting frequency.

[0073] When the air conditioner works in the heating mode, the outdoor unit absorbs heat and the indoor unit dissipates heat. Since the outdoor ambient temperature is usually below ten degrees, when the outdoor unit still needs to absorb heat, the temperature of the evaporator body will drop below 0 degrees. The surrounding moisture (similar to dehumidification during refrigeration) will quickly condense into frost. After the evaporator is frosted, the low-temperature refrigerant cannot be evaporated when it passes through the externa...

Abstract

The invention discloses an air conditioner defrosting control method and further discloses an air conditioner and a storage medium. The air conditioner defrosting control method comprises the steps that after the air conditioner enters in a defrosting mode, the initial defrosting frequency of the air conditioner is obtained, the air conditioner is controlled to conduct defrosting according to theinitial defrosting frequency, the exhaust pressure of the air conditioner is obtained, and when the exhaust pressure is larger than or equal to preset defrosting pressure, the defrosting frequency ofthe air conditioner is decreased. Defrosting is started by adopting a high frequency, the exhaust pressure of the air conditioner is monitored in the defrosting process, the defrosting frequency is decreased step by step according to the exhaust pressure, defrosting can be conducted by appropriately using the high frequency, the defrosting time is shortened, the indoor temperature can be advantageously maintained, and the heating effect of the air conditioner is improved.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to an air conditioner defrosting control method, an air conditioner and a storage medium. Background technique [0002] With the enhancement of the society and the government's awareness of environmental protection, the disadvantages of the previous northern boiler central heating are becoming more and more obvious, and an environmentally friendly heating method is urgently needed to replace it. In recent years, the use of air conditioning and heating functions for heating has gradually become an upsurge. However, during the heating process of the air conditioner under the condition of low outdoor temperature, the outdoor unit of the air conditioner is prone to frost, resulting in a decrease in the heating effect, and defrosting becomes an important link in the operation process of the air conditioner. [0003] At present, the frequency conversion air conditioners on the market use ...
