Embodiment 1

[0034] Based on the fact that in the related art, there is no accurate control mechanism in the process of turning on the anti-condensation mode, which leads to the problem that the air conditioner cannot accurately judge when to enter the anti-condensation mode. control method, the flow of the method is as follows figure 1 As shown, including step S102 to step S108:

[0035] Step S102, detecting whether the air conditioner is in cooling mode or dehumidification mode. If yes, go to step S104; otherwise, continue to detect.

[0036] In the implementation process, if it is not in the cooling or dehumidification mode, the detection may not be performed immediately, but a detection time is set, and the current operation mode is detected when the detection time arrives.

[0037] Step S104, detecting the internal ambient temperature, external ambient temperature, and evaporator tube temperature of the air conditioner, and judging whether the internal ambient temperature is lower t...

Embodiment 2

[0043] In the related art, there is no accurate control mechanism in the process of turning on the anti-condensation mode, which leads to the problem that the air conditioner cannot accurately judge when to enter the anti-condensation mode. Embodiments of the present invention provide a control method for the air-conditioning mode. The process of this method can be as follows figure 2 As shown, including step 202 to step S206:

[0044] Step 202, obtaining the current temperature state of the air conditioner in cooling mode or dehumidification mode, wherein the temperature state includes: internal ambient temperature, external ambient temperature, and evaporator tube temperature;

[0045] Step 204, judging whether the temperature state meets the first preset condition, wherein the first preset condition is that the internal ambient temperature does not exceed the first threshold T1, the external ambient temperature does not exceed the second threshold T2, and the temperature o...

Embodiment 3

[0063] This preferred embodiment provides a method for controlling the anti-condensation mode of an inverter air conditioner. The flow of the method is as follows image 3 As shown, including step S302 to step S314:

[0064] In step S302, the air conditioner is turned on, and it is judged whether a preset temperature condition is satisfied. Among them, the preset temperature conditions include: (1) the compressor is turned on, and the four-way valve (if any) is not powered on; (2) the internal ambient temperature T of the air conditioner 1 (T inner ring) is less than the predetermined temperature Ts 1 , the external ambient temperature T of the air-conditioning equipment 2 (T outer ring) is less than the predetermined temperature Ts 2 , the temperature T in the evaporator tube 3 (T inner tube) is less than the predetermined temperature Ts 3 ; (3) T inner ring-T inner tube is greater than the predetermined temperature Ts 4 .

[0065] If the above conditions are met at th...

Abstract

The invention discloses a method and device for preventing an air conditioner from condensing. The control method includes detecting the current temperature state of the air conditioner, comparing the state with a preset threshold, and judging whether the current state satisfies the preset threshold or not; if so, detecting the temperature, and starting a condensation preventing mode on the condition of passing through all detections. By the aid of the method, the problem that since an accurate control mechanism is not provided in the process of starting the condensation preventing mode in the prior art, an air conditioner cannot judge exactly when the air conditioner is in the condensation preventing mode is solved, and performances of the air conditioner are improved.

Description

technical field [0001] The present invention relates to the field of air conditioners, and more specifically, to a control method and device for preventing condensation in an air conditioner. Background technique [0002] In people's daily life, the importance of air-conditioning cannot be ignored. However, in the process of using air-conditioning, some problems have also occurred one after another. [0003] During the rainy season in the south, if the user does not keep the airtightness of the room when using the air conditioner, it is easy to experience long-term high temperature and high humidity. In this case, the air conditioner will generate a large amount of condensation, which not only affects the use of the air conditioner, but also reduces user experience. [0004] For users who use inverter air conditioners, the frequency adjustable feature of the inverter air conditioner enables the cooling capacity and outlet air temperature of the air conditioner to intelligen...
