Embodiment 1

[0040] In this embodiment, a method for controlling an air conditioner is provided. The air conditioner includes an indoor side fan and an indoor side heat exchanger, and the air conditioner is provided with an anti-frost program. Specifically, the control method includes: after the air conditioner enters the dehumidification mode, executing an anti-frost program;

[0041] The anti-frost program includes: according to the outdoor ambient temperature t 0 and the indoor ambient temperature to adjust the heat exchange on the indoor side of the air conditioner, where when the outdoor ambient temperature t 0 Not lower than the first preset temperature t 1 And / or the indoor ambient temperature is not lower than the second preset temperature t 3 , keep the speed of the indoor side fan constant; when the outdoor ambient temperature t 0 lower than the first preset temperature t 1 And the indoor ambient temperature is lower than the second preset temperature t 3 , increase the spe...

Embodiment 2

[0053] In this embodiment, an air conditioner is provided, and the air conditioner adopts the control method in Embodiment 1.

[0054] Preferably, the air conditioner includes: an outdoor unit and a temperature measuring component. The temperature measuring component includes: a first temperature-sensing package arranged on the outdoor unit, which is used to detect the outdoor ambient temperature; and a second temperature-sensing package arranged on the indoor unit of the air conditioner, which is used to detect the indoor temperature. ambient temperature.

[0055] Such as figure 1 As shown, the air conditioner in this embodiment has the following control logic. Specifically, in the control logic of the air conditioner system, the outdoor ambient temperature t 0 , refers to the ambient temperature sensed by the external environmental tube temperature bulb of the outdoor unit; the first preset temperature t 1 Refers to a specific value, reflected in the underlying program, ...

Abstract

The invention discloses a control method of an air conditioner and the air conditioner. The air conditioner comprises an indoor side draught fan and an indoor side heat exchanger, and the air conditioner is provided with an anti-frosting program. The control method comprises the steps that when the air conditioner is in a dehumidification mode, the anti-frosting program is executed; and the anti-frosting program comprises the step that when the outdoor environment temperature is lower than the first preset temperature and the indoor environment temperature is lower than the second preset temperature, the rotating speed of the indoor side draught fan is increased according to a preset rule so as to prevent the indoor side heat exchanger from frosting.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner control method and an air conditioner. Background technique [0002] At present, the only way for household air conditioners to deal with returning to the south in spring in the south is to force the cooling mode to dehumidify the air in the room when the ambient temperature is low. Running the cooling mode at low temperature will often make the evaporator tube temperature too If the temperature is low, the evaporator will frost, which will affect the heat transfer of the evaporator. Some existing air conditioners use two indoor heat exchangers to optimize the constant temperature and dehumidification of the air conditioner, but the cost is relatively high; or the electric heating and solenoid valves on the bypass pipes of the refrigerant inlet and refrigerant outlet of the internal unit are turned on to prevent freezing Protection, this method also n...
