Embodiment Construction

[0055] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0056] The invention provides a control method of an air conditioner.

[0057] refer to figure 1 , figure 1 It is a schematic flowchart of the first embodiment of the control method of the air conditioner of the present invention.

[0058] In one embodiment, the control method of the air conditioner includes:

[0059] Step S10, after the air conditioner turns on the heating mode, obtain the temperature of the evaporation coil of the outdoor unit of the air conditioner;

[0060] In this embodiment, after the air conditioner is turned on, it is determined whether the air conditioner is in the heating mode, and if it is in the heating mode, the temperature of the evaporation coil of the outdoor unit of the air conditioner is acquired in real time. For example, a temperature sensor can be fixed on the evaporation coil...

Abstract

The invention discloses an air conditioner control method. The method includes after an air conditioner operates in a heating mode, acquiring the temperature of an evaporation coil of an air conditioner outdoor unit; judging whether the temperature of the evaporation coil is smaller than a first preset temperature or not; if so, increasing the rotation speed of an air conditioner outdoor fan. The invention further discloses an air conditioner. After the air conditioner operates in a heating mode, the temperature of the evaporation coil of the air conditioner outdoor unit is detected, when the temperature of the evaporation coil is smaller than the first preset temperature, the rotation speed of the air conditioner outdoor fan is increased, the heat exchange between the outdoor evaporator and the outdoor air is accelerated, the frosting velocity of the air conditioner outdoor evaporator is decreased, the interval time between two adjacent defrosting operations is prolonged, excessively frequent air conditioner defrosting operation is avoided, the indoor temperature is stable constantly, and the comfort for using the air conditioner to heat is improved for users.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner control method and the air conditioner. Background technique [0002] When the air conditioner is used for heating in winter, frost is easy to form on the heat exchange coil of the outdoor unit of the air conditioner, so the heat exchanger of the outdoor unit must be defrosted during the operation of the air conditioner. [0003] The existing defrosting method generally judges whether the temperature of the heat exchange coil of the outdoor unit is lower than a preset threshold, and turns on the defrosting mode when it is lower than the preset threshold. The defect of the existing defrosting method is that the defrosting action is too frequent, especially when the outdoor temperature is low. After each defrosting is completed, the temperature of the heat exchange coil can be lower than the preset threshold in a short period of time. Therefore, the def...
