The above methods all have defects: the flocking method can only solve the problem for a short time, and the flannel is easy to breed mold in a humid environment for a long time, which affects environmental hygiene; the electric heating method will affect the air temperature; changing the air supply mode will generate additional noise, and Conflict with user-set air supply mode
These two methods have disadvantages: the running time is set in advance, and cannot be adjusted according to the actual environment in which the air conditioner operates, and the practicability is poor; the installation of a humidity sensor will lead to an increase in cost

Embodiment 1
[0023] This preferred embodiment provides an air conditioner control method. Such as figure 1 As shown, the method includes the following steps:
[0024] Step 1. After starting up, judge whether the air conditioner is in cooling mode, if yes, go to step 2, otherwise go to step 7.
[0025] Step 2. Use the first temperature sensing package of the indoor unit to detect the temperature value at the copper pipe of the indoor unit, so that the temperature at the copper pipe of the indoor unit is the inner pipe temperature value Tn.
[0026] Step 3. Substitute the inner tube temperature value Tn into the formula: wet bulb temperature Ts=A×inner tube temperature value Tn+B, and calculate the wet bulb temperature Ts; where A and B are constants, and A∈[-10,10 ], B ∈ [-20, 20].
[0027] Step 4. Use the second temperature-sensing package of the indoor unit to detect the temperature value at the air return port of the indoor unit, so that the temperature at the air return port of the i...
Embodiment 2
[0036] This preferred embodiment provides an air conditioner control method. The method is that when it is judged that the air conditioner is in cooling mode, the temperature value Tn of the inner tube detected by the first temperature sensing package of the indoor unit is brought into the formula wet bulb temperature Ts=A×inner tube temperature value Tn+B to calculate the wet bulb temperature Ts, Among them, A and B are constants, A ∈ [-10, 10], B ∈ [-20, 20]; according to the wet bulb temperature Ts and dry bulb temperature Tg, the dry bulb temperature Tg and wet The relative humidity value S is obtained from the table corresponding to the bulb temperature Ts, and the air conditioner enters the anti-condensation operation mode when the relative humidity value S is greater than or equal to 60%.
[0037] The table composed of the dry bulb temperature Tg and the wet bulb temperature Ts in the psychrometric chart is as follows:
[0038]

Abstract
The invention discloses an air conditioner control method, belongs to the field of an anti-condensation control method of an air conditioning device and is designed for solving the problems of high cost, poor practicability and the like of the existing method. The air conditioner control method comprises the following steps: when judging that an air conditioner is in a refrigeration mode, substituting an inner pipe temperature value Tn detected by a first thermometer bulb of an indoor unit into a formula, namely a wet bulb temperature Ts=A* inner pipe temperature value Tn+B, so as to obtain the wet bulb temperature Ts, wherein A and B are constant numbers, the A belongs to [-10,10] and the B belongs to [-20,20]; obtaining a relative humidity value S by checking a psychrometric chart or checking a table composed of dry bulb temperatures Tg and wet bulb temperatures Ts in the psychrometric chart; and when the relative humidity value S is more than or equal to 60%, enabling the air conditioner to enter an anti-condensation operation mode. The air conditioner control method can be used for accurately judging according to an actual working environment of the air conditioner and has strong practicability and good anti-condensation effect.
Description
technical field [0001] The invention relates to an anti-condensation control method of an air conditioner. Background technique [0002] In the use of the air conditioner, once the condensation problem occurs, water will condense on the surface of the air conditioner structure and drip, or water droplets will be blown out during the air supply process, which will affect the user's experience. [0003] The current anti-condensation methods include: pasting flocking cloth on the wind deflector; or adding electric heating; or changing the air supply mode. The above methods all have defects: the flocking method can only solve the problem for a short time, and the flannelette is prone to mold in a humid environment for a long time, which affects environmental sanitation; the electric heating method will affect the air temperature; changing the air supply mode will generate additional noise, and It conflicts with the air supply mode set by the user. [0004] Existing methods for...
