Embodiment approach

[0041] According to a preferred embodiment of the present invention, the upper limit allowable adjustment speed includes a first upper limit allowable adjustment speed and a second upper limit allowable adjustment speed, and the lower limit allowable adjustment speed includes a first lower limit allowable adjustment speed and a second lower limit allowable adjustment speed Rotating speed.

[0042] In a specific implementation, the first upper limit of each wind gear allows adjustment of the rotational speed equal to the operating speed Pn corresponding to the wind gear plus the operating speed Pn corresponding to the wind gear and the corresponding operating speed Pn corresponding to the next wind gear- The product of the difference between 1 (Pn>Pn-1) and the first preset coefficient a1, that is, the first upper limit allows adjustment of rotational speed=Pn+(Pn-Pn-1)*a1, for example a1=0.5, the first upper limit allows adjustment Speed=Pn+(Pn-Pn-1)*0.5.

[0043] The second ...

Abstract

The invention provides a water multi-connected air conditioner and its control method, device and storage medium. The method includes: detecting the temperature difference between the target room temperature of the room where the internal unit is located and the current room temperature of the room; according to the temperature difference Control the fan of the internal unit to operate according to the operating speed of the set wind gear, the upper limit allowable adjustable speed or the lower limit allowable adjustable speed. The solution provided by the present invention can quickly reach the target room temperature set by the user by increasing the load output on the premise of setting the wind gear by the user.

Description

technical field [0001] The invention relates to the field of control, in particular to a water multi-connected air conditioner and its control method, device and storage medium. Background technique [0002] The main body of the water multi-unit air conditioner is mainly for cooling, taking into account the heating operation. The fan coil unit or floor heating is installed in the room to realize cooling or heating. When the fan coil unit is used as the indoor unit to run, the cold and hot water generator It mainly plays the role of providing suitable water temperature, cold and hot water. Under the existing technical conditions, after the user sets the room temperature control target and the operating speed of the indoor fan, affected by the uncertain load of the room, it is easy to find that the room temperature is difficult to reach the set value during the actual operation process. If the target value is set or the room temperature exceeds the set target value, it will se...
