Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
First embodiment, an embodiment of the present invention provides a method for controlling cold air prevention of an air conditioner, as shown in fig. 1, including:
s101, when the air conditioner starts a heating function, the indoor environment temperature and the indoor coil temperature are obtained.
And S102, determining the cold-proof air temperature according to the indoor environment temperature.

It should be noted that the cold air prevention temperature or the set rotation speed is determined according to different indoor environment temperatures, and calculation can be performed according to actual conditions; illustratively, with an initial rotational speed of N1The maximum rotating speed is N2The initial cold-proof wind temperature is TS1The highest cold-proof air temperature is TS2For illustration, the specific implementation is as follows:
1. when the indoor ambient temperature TinLess than or equal to a first preset temperature T1And the indoor coil temperature Tc0Heating to Ts1In time, the indoor fan is controlled to be N0＝N1The air is blown at the set rotating speed.
2. When the indoor ambient temperature TinGreater than a first predetermined temperature T1Indoor ambient temperature TinLess than or equal to a second preset temperature T2And the indoor coil temperature Tc0Heating to TinAt + A, the indoor fan is controlled to
The air is blown at the set rotating speed.
3. When the indoor ambient temperature TinGreater than a second predetermined temperature T2Indoor ambient temperature TinLess than or equal to a third preset temperature T3And the indoor coil temperature Tc0Heating to C x TinAt + B, the indoor fan is controlled to
The air is blown at the set rotating speed.
4. When the indoor ambient temperature TinGreater than a third predetermined temperature T3And the indoor coil temperature Tc0Heating to Ts2In time, the indoor fan is controlled to be N0＝N2Setting of rotationAnd (5) rapidly blowing air.
Wherein, Ts1And Ts2Determined by the electrical heating and rotation speed of the prototype, generally Ts1The value is 5-15 ℃, and the general T iss2The value is 15-25 deg.C, the air supply distance of the prototype is taken into consideration, the proper set rotation speed is selected, the electric heating power is taken into consideration according to the selected set rotation speed, and when the power is higher, T is highers1And Ts2The lower may be selected; at lower power, Ts1And Ts2Higher ones, but not one, smaller ones, and one, larger ones △ M1Representing a set rate of change of speed per degree celsius,
meaning that the integer is taken and the rounding rule is rounding (e.g. when
When the value is equal to 1.5, the value is 2; when in use
1) when equal to 1.4, N2＞N1，35℃＞T3＞T2＞T1＞-35℃，A＝Ts1-T 10 < C < 1, and satisfies T2+A＝C*T2+B。
Illustratively, taking a certain 1.5P air conditioner as an example, T is set1＝-5℃，T2＝0℃，T 36 deg.C, initial rotation speed of 100 revolutions, maximum rotation speed of 400 revolutions, Ts1＝10℃，Ts2＝17℃，A＝15，B＝15，C＝0.4，△M1For example, 50, the specific implementation is as follows:
according to the calculation formulas of the cold air preventing temperature and the set rotating speed corresponding to different indoor environment temperatures, the indoor environment temperature, the indoor coil temperature and the set rotating speed N can be known0The relationship of the change in the value of (a) is shown in figure 3,
as shown in fig. 4, after the indoor fan is started, the temperature of the indoor coil pipe continuously rises along with the start of the press, and the set rotating speed of the indoor fan also rises along with the start of the press, and the control is as follows:
if Tc(n+1)＝Tc(n)+ △ T, then there is N(n+1)＝N(n)+△M2；
Wherein △ T ═ D and D > 0, △ M2＝(△T*(Ns-N0))/(Tcaim-Tc0) Or △ M2＝△T*((Ns-N0)/(Tcaim-Tc0))，NsSetting the rotating speed of the fan for the startup of a user, and meeting Ns＞N2，TcaimPreventing the cold air from exiting the indoor coil pipe; illustratively, when the indoor coil temperature is greater than TcaimAnd when the fan is started, the rotating speed runs according to the set rotating speed set by starting, and the cold wind prevention related setting is invalid (the set rotating speed of the indoor fan is not changed according to the temperature of the cold wind prevention any more).
It should be noted that in practical applications, D is generally 2-3 ℃.
Starting up the indoor environment temperature T by using a certain 1.5 piece of air conditionerin＝6℃，T c017 deg.C, initial rotation speed 400 rpm, △ T3 deg.C, TcaimWhen the maximum rotation speed is 1100 rpm at 38 ℃, the number of times of superposition n and the indoor coil temperature T are shown in fig. 5cAnd a set rotation speed N0The corresponding relationship table of (2).
Through the control, the starting machine can be started to blow hot air in time, the rotating speed is increased along with the increase of the temperature of the inner disc in the later period, the heating capacity of a prototype is furthest exerted while hot air is blown by the prototype, the use comfort of a user is improved, and the market competitiveness of a product is improved.
