[0039] see figure 1 , which is a schematic flowchart of a low-temperature refrigeration method for an air conditioner provided in the first embodiment of the present invention. The low-temperature refrigeration method of the air conditioner comprises:

[0040] Step S10, acquiring the temperature value of the external disk.

[0041] The temperature value of the external disk may be acquired periodically, for example, the cycle interval is set to 10s, that is, the temperature value of the external disk is acquired once every 10s.

[0042] Step S20, acquiring the change trend of the temperature value of the external disk.

[0043] The change trend can be obtained according to the currently obtained external disk temperature value and the change of the external disk temperature value obtained before it. For example, according to the difference between the current outer disk temperature value and the previous outer disk temperature value, the change trend can be obtained as incr...

Abstract

The invention provides a low-temperature refrigeration method and device for an air conditioner, and an air conditioner. The low-temperature cooling method of the air conditioner includes: obtaining the temperature value of the external disk; obtaining the change trend of the temperature value of the external disk; and controlling the external fan to perform corresponding actions according to the change trend. It solves the problem that the temperature of the evaporator is low when the air conditioner is cooling at low temperature.

Description

technical field [0001] The invention relates to the technical field of air conditioner control, in particular to a low-temperature refrigeration method for an air conditioner, a low-temperature refrigeration device for an air conditioner, and an air conditioner. Background technique [0002] Special places require air conditioners to be used in low temperature environments. However, when the air conditioner is operating in a low-temperature environment, the evaporation temperature is low due to the good heat dissipation of the external unit; it is easy to cause the indoor unit to freeze due to the low evaporation temperature, thereby affecting the cooling effect of the air conditioner. [0003] It can be seen that in the prior art, there is a problem that the temperature of the evaporator is low when the air conditioner is used for cooling at low temperature. Contents of the invention [0004] The invention solves the problem that the temperature of the evaporator is low ...
