After the first heating part is controlled by the processor to stop heating, the temperature of the outdoor coil is continuously monitored, and the judging process of the temperature of the outdoor coil is continuously carried out, so that the frosting condition is monitored and avoided.
Optionally, the air conditioner further comprises: and a second heating unit, provided in the indoor unit, configured to heat an indoor space in which the air conditioner is located.
Optionally, the method for controlling an air conditioner further includes: the processor controls the second heating portion to initiate heating if the indoor coil temperature is less than the third coil temperature threshold. Therefore, the indoor heating effect can be achieved quickly, and the user experience is optimized.
Optionally, the throttle device in the air conditioner is an electronic expansion valve.
As shown in connection with fig. 5, an embodiment of the present disclosure provides another method for controlling an air conditioner, including:
s501, during operation in heating mode, the processor monitors the outdoor coil temperature.
And S502, when the temperature of the outdoor coil is smaller than the temperature threshold value of the outdoor coil, the processor controls the electronic expansion valve to increase the opening degree to the defrosting opening degree, and controls the first heating part to operate and heat.
Therefore, defrosting is achieved by increasing the opening of the electronic expansion valve, and meanwhile, the first heating part is controlled to operate and heat so as to supplement heat, and heating and defrosting efficiency are improved.
Optionally, the processor controls the electronic expansion valve to increase the opening degree to the defrosting opening degree, and controls the first heating part to operate and heat, including: the processor controls the electronic expansion valve to increase the opening degree to the defrosting opening degree, and controls the first heating part to operate and heat after the third duration. Wherein the value range of the third time period is 30s to 2min. Preferably 1min. In this way, by controlling the first heating portion to operate for heating after the third period of time by increasing the opening degree of the electronic expansion valve, it is possible to avoid liquid impact caused by the opening degree of the electronic expansion valve.
Optionally, the defrosting opening degree includes: full open degree. Thus, the defrosting efficiency can be ensured to the greatest extent.
Optionally, the determining method of the defrosting opening degree includes: the processor obtains indoor air outlet temperature and determines the defrosting opening degree of the electronic expansion valve according to the indoor air outlet temperature. The indoor air outlet temperature can reflect frosting conditions, and matching the opening of the electronic expansion valve according to the indoor air outlet temperature is beneficial to guaranteeing coordination and unification between the defrosting opening of the electronic expansion valve and the frosting conditions, and avoiding unnecessary negative influence on the throttling process caused by overlarge opening of the electronic expansion valve while guaranteeing defrosting effect.
Optionally, the processor determines a defrosting opening degree of the electronic expansion valve according to indoor air outlet temperature, including: and under the condition that the indoor air outlet temperature is larger than the first air outlet temperature threshold value, the processor determines that the defrosting opening degree of the electronic expansion valve is the first opening degree. And under the condition that the indoor air outlet temperature is less than or equal to the first air outlet temperature threshold value, the processor determines that the defrosting opening degree of the electronic expansion valve is the second opening degree. Wherein the first opening is smaller than the second opening. The indoor air outlet temperature is lower, and the frosting condition of the air conditioner is severe, and at the moment, the electronic expansion valve is opened to a larger opening degree, so that the defrosting with larger intensity is realized, the defrosting effect is optimized, and the defrosting time is shortened. The indoor air outlet temperature is higher, so that the frosting condition of the air conditioner is lighter, the electronic expansion valve is opened to a smaller opening degree, the unnecessary increase of the opening degree of the electronic expansion valve is reduced as much as possible while the defrosting effect is ensured, and the influence on heating circulation is reduced.
Optionally, the processor determines the opening degree of the electronic expansion valve according to the indoor air outlet temperature, including: and under the condition that the indoor air outlet temperature is greater than the first air outlet threshold value, the processor determines that the defrosting opening degree of the electronic expansion valve is the first opening degree. And under the condition that the indoor air outlet temperature is smaller than or equal to the first air outlet temperature threshold value and larger than the second air outlet temperature threshold value, the processor determines that the defrosting opening of the electronic expansion valve is the second opening. And under the condition that the indoor air outlet temperature is less than or equal to the second air outlet temperature threshold value, the processor determines that the defrosting opening degree of the electronic expansion valve is the third opening degree. Wherein the first opening is smaller than the second opening, and the second opening is smaller than the third opening. Therefore, the indoor air outlet temperature is divided more finely and corresponds to different opening degrees of the electronic expansion valve respectively, and accuracy of the opening degree determining process of the electronic expansion valve is improved. It can be understood that in practical application, the indoor air outlet temperature can be segmented less or more according to practical requirements, and the opening of the corresponding electronic expansion valve can be adjusted.
Illustratively, the first opening is 400 steps, the second opening is 430 steps, and the third opening is 480 steps.
The determining mode of the first air outlet temperature threshold value and the second air outlet temperature threshold value comprises the following steps: when the outdoor coil temperature meets a temperature threshold value smaller than the first defrosting temperature, the processor determines that the air outlet temperature at the moment is the initial air outlet temperature Tc0, and determines a first air outlet temperature threshold value and a second air outlet temperature threshold value according to the initial air outlet temperature. More specifically, the processor determines the first outlet air temperature threshold as the difference of the initial outlet air temperature minus the first temperature and the second outlet air temperature threshold as the difference of the initial outlet air temperature minus the second temperature. Wherein the first temperature is less than the second temperature. For example, the first outlet air temperature threshold is Tc0-1, and the second outlet air temperature threshold is Tc0-2. Therefore, the air outlet temperature threshold value is set according to the actual running condition, and the accuracy of the air outlet temperature threshold value is improved.
