Detailed Description
In order to make the technical means, the creation characteristics, the achievement purposes and the functions of the invention clearer and easier to understand, the invention is further explained by combining the drawings and the detailed implementation mode:
as shown in fig. 1, the present invention provides a temperature control and dehumidification control method, which comprises the following steps: s1, starting a temperature control dehumidification mode; s2, running in a refrigeration mode for a first preset time t 1; s3, detecting the current indoor environment temperature Tir, wherein the Tir is equal to or less than a preset temperature threshold value, and entering a step S4; if the Tir is larger than the preset temperature threshold, the step S5 is entered; s4, detecting the current indoor environment temperature Tir and the relative humidity Phiir, calculating the current moisture content Dir, entering a step S6 when the moisture content Dir is smaller than or equal to a preset moisture content threshold, and entering a step S7 when the Dir is larger than the preset moisture content threshold; s5, detecting the current indoor environment temperature Tir and the relative humidity Phiir, calculating the current moisture content Dir, entering a step S8 when the moisture content Dir is equal to or less than a preset moisture content threshold, and entering a step S2 when the moisture content Dir is greater than the preset moisture content threshold; s6, stopping the compressor, reducing the rotating speed of the indoor fan to a preset rotating speed, and after running for a third preset time t3, entering S3; s7, entering a heating mode, and after running for a fourth preset time t4, entering S2; and S8, reducing the frequency of the compressor to a preset lowest frequency, increasing the rotating speed of the fan of the indoor unit to a preset highest rotating speed, and after the operation is carried out for a second preset time t2, entering S3. The humidity in the air is used to replace the relative humidity to serve as the judgment standard of the dehumidification effect, so that the comfort of a user in the use process can be improved, and meanwhile, the control is accurate and simple.
In step S2, the frequency of the compressor in the cooling mode is adjusted to the highest frequency, so as to achieve the purpose of rapid cooling and dehumidification. In S3, the current indoor environment temperature Tir is obtained through detection, and meanwhile the temperature Ts set by a user is obtained, the preset temperature threshold value of the indoor environment temperature is Ts + delta T, wherein the delta T is preferably a range value of 0-1.5 ℃. In S4, a set moisture content Ds is obtained at the same time, a preset moisture content threshold value is Ds + delta D, wherein delta D is preferably a range value of 0-1.0g/kg, and the set moisture content Ds is the most comfortable moisture content corresponding to the temperature set by the user; the calculation of said set moisture content Ds is obtained by means of a wet air state diagram, which is well known in the industry.
In step S6, the preset rotation speed of the fan is ψ 300+ Tir, where Tir is the current indoor environment temperature and a is a constant 20. In step S7, the heating mode is operated at the lowest frequency preset by the compressor, and the indoor fan is operated at the lowest rotation speed preset, so that the indoor temperature can slowly rise, and the temperature is prevented from rising too fast to improve the fitness of the human body. In step S8, the compressor operates at a preset minimum frequency, the rotation speed of the indoor fan is a preset maximum rotation speed, so as to reduce the room temperature, the temperature Tc of the inner panel is reduced due to the temperature of the inner panel being too high or too low in frequency, the compressor operates at the preset minimum frequency, and the rotation speed of the indoor fan is a preset maximum rotation speed, so as to control the temperature Tc of the inner panel between the indoor environment temperature Tir and the dew point temperature TL, where TL < Tc < Tir, and since the dew water is generated only when the temperature Tc of the inner panel is lower than the dew point temperature TL, the moisture content Dir in the room is reduced, and the room temperature is reduced by controlling TL < Tc < Tir, and at the same time, the moisture content Dir in the room is ensured to be unchanged.
