Embodiment Construction

[0029] An embodiment of the present invention provides an air conditioner control method. The air conditioner in the embodiment of the present invention is a split heat pump air conditioner that utilizes a steam cycle refrigeration system to realize indoor cooling / heating functions. The air conditioner has an air conditioner outdoor unit and an air conditioner indoor unit, and the four-way valve is used to realize the flow direction conversion of the refrigerant and realize the switching between the cooling mode and the heating mode. figure 1 is a schematic diagram of an air conditioner control method according to an embodiment of the present invention.

[0030] Such as figure 1 As shown, the air conditioner control method in the embodiment of the present invention may generally include the following steps:

[0031] Step S101: The air conditioner operates in a heating mode.

[0032] Step S102: Determine whether the outdoor ambient temperature is lower than the first preset ...

Abstract

The invention provides a control method and a control device of an air conditioner. The control method comprises the following steps: judging whether the outdoor environmental temperature is smaller than a first preset temperature when the air conditioner operates in a heating mode; if the outdoor temperature is smaller than the first preset temperature, detecting whether people are indoor or not; if people are indoors, controlling the air conditioner to enter in a first defrosting mode so as to defrost an outdoor unit of the air conditioner; and if people are not indoor, controlling the air conditioner to enter in a second defrosting mode so as to defrost the outdoor unit of the air conditioner. According to the control method and the control device of the air conditioner provided by the invention, different defrosting modes are selected according to whether people are indoor or not, and human factors are considered. Compared with the prior art, the temperature factor of an outdoor heat exchanger is only considered. The control method provided by the invention is more reasonable.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to an air conditioner control method and control device. Background technique [0002] After the air conditioner has been running for heating for a period of time, it is necessary to defrost the heat exchanger of the outdoor unit. Most of the existing defrosting methods are real-time detection of the surface temperature of the heat exchanger of the outdoor unit. As long as the surface temperature of the heat exchanger of the outdoor unit is lower than the preset temperature, the four-way valve is controlled to change the refrigerant flow direction, so that the air conditioner enters the heating mode from the heating mode. In cooling mode, defrost the heat exchanger of the outdoor unit. [0003] The above method can complete the defrosting of the outdoor unit, but since the air conditioner is in cooling operation during the defrosting process, the indoor ambient temperature wi...
