Alternative embodiments of the present invention are described in detail below with reference to the accompanying drawings.
Example 1
The embodiment provides a tuyere switching control method, which is applied to a regional control system, fig. 1 is a schematic structural diagram of the regional control system according to the embodiment of the invention, and as shown in fig. 1, 1 is a connecting pipe between a room tuyere and a main air duct; 2 is a main air outlet pipe; 3, an air valve is used for controlling the connection and the disconnection between the air inlet connecting pipe of the current room and the main air pipe; and 4 is a main air return pipe. The inner machine returns air in the main air return pipe and outputs air in the main air outlet pipe.
Each area is provided with at least two air ports, each air port is provided with two air valves, one air valve is an air outlet air valve connected to a main air outlet pipe 2 of the indoor unit, and the other air valve is a return air valve connected to a main return air pipe 4 of the indoor unit. In fig. 1, two rooms are illustrated as an example, but the number of the rooms is not limited to 2, and more rooms can be added. The following description uses two rooms for ease of description:
each room is provided with two air ports, and each air port is respectively connected to the main air outlet pipe and the main air return pipe on two sides. When the front air port needs to be set as the air outlet, the air valve connected to the main air outlet pipe is opened, and the air valve connected to the main air return pipe 2 is closed. When the front air inlet needs to be set as the return air inlet, the air valve connected to the main return air pipe 4 is opened, and the air valve connected to the main air outlet is closed.

step S201, monitoring the running state and the indoor temperature of each area;
and S202, controlling the opening and closing of an air outlet valve and an air return valve of each air port in the area according to the running state and the indoor temperature.
The operation states mentioned in this embodiment are specifically divided into an operating state and a non-operating state, and the operating state may be, for example: a cooling mode, a heating mode, a dehumidification mode, and the like, and the non-operation state may be, for example: standby state, shutdown state, etc.
1. If the running state is the working state, controlling the opening and closing of an air outlet valve and an air return valve of each air port in the area according to whether the indoor temperature reaches the preset temperature;
1) if the indoor temperature reaches the preset temperature, controlling the air outlet valves of the air outlets of the first preset number in the area to be opened and the air return valves to be closed, and controlling the air return valves of the rest air outlets to be opened and the air outlet valves to be closed; in order to balance the number of the air outlets and the air return inlets, a first preset number which is approximately equal to the total number of the air outlets/2 in the area is generally set. Specifically, when the total number n of the air ports in the region is an even number, the first preset number is n/2; when the total number n of the air ports in the area is an odd number, the first preset number is (n + 1)/2. Based on this, can guarantee the equilibrium of air-out and return air in this region, better maintenance current operation effect.
2) If the indoor temperature does not reach the preset temperature, indicating that the refrigeration needs to be continued, controlling the air outlet valves of the air outlets with the second preset number in the area to be opened and the air return valves to be closed, and controlling the air return valves of the rest air outlets to be opened and the air outlet valves to be closed.
It should be noted that the second preset number is greater than the first preset number. Most wind gaps in the region are used as air outlets, and a few wind gaps are used as air return inlets, so that the operation effect can be achieved more quickly and efficiently, and the user experience is improved. Of course, in order to achieve the most rapid and efficient operation effect, the second preset number may be set to be equal to the total number of the air outlets in the area, that is, all the air outlets are used as the air outlets. In addition, the specific setting of the second preset number may also refer to a difference between the current indoor temperature and the preset temperature, that is, calculate a difference between the indoor temperature and the preset temperature, and determine the second preset number according to the difference; wherein the larger the difference, the larger the second preset number. If the current temperature does not reach the preset temperature, the quantity of the air return inlets is increased, and the quantity of the air outlets is reduced, so that the indoor temperature is adjusted to the preset temperature more quickly and efficiently, and the user experience is improved.
2. And if the operation state is a non-working state, controlling the return air valve of each air inlet in the area to be opened and the outlet air valve to be closed, namely, each air inlet in the area is used as a return air inlet.
The control scheme of the regional control system is provided aiming at a one-to-one regional control mechanism of the regional control system, at least two air ports are installed in each region, each air port is connected with two air valves, the two air valves are respectively connected to an air outlet pipe and an air return pipe of an internal machine, the air valve settings of the air outlet and the air return pipe are automatically controlled according to the user requirements, the operation effect of the region where a user is located is the best, and the user experience degree is improved.
The following table 1 is a tuyere state table. The technical scheme of the invention is described by taking two tuyeres (tuyere 1 and tuyere 2) as an example.
TABLE 1
Serial number Tuyere 1 Tuyere 2
1 Air outlet Air outlet
2 Air outlet Return air inlet
3 Return air inlet Return air inlet
When the air inlet 1 is communicated with the main air outlet pipe, and the air inlet 2 is communicated with the main air outlet pipe, the current room is set to be in a state 1. When the air inlet 1 is communicated with the main air outlet pipe and the air inlet 2 is communicated with the main air return pipe, the current room is set to be in the state 2. When the air inlet 1 is communicated with the main air return pipe and the air inlet 2 is communicated with the main air return pipe, the current room is set to be in a state 3.
Fig. 3 is a flow chart of zone control in the cooling mode according to an embodiment of the present invention, which is described by taking the cooling demand in the room as an example, and as shown in fig. 3, the flow chart includes:
the regional control system judges whether the room is started to be refrigerated by a user or not;
if the user does not use the area control terminal to start the refrigeration function of the room, the room is in a shutdown state, and the air inlet state is switched to the state 3 in the table 1, namely, the two air inlets are both return inlets. Therefore, the room which is not started is set as the air return opening, so that the energy is saved, and the fresh air effect is brought to the area.
If the regional control system judges that the room is started to be refrigerated by the user, whether the room reaches a set temperature point is judged, if the room does not reach the set temperature point, the air ports are switched to the state 1 in the table 1, namely, the two air ports are air outlets, the refrigerating effect of the region is greatly enhanced, and the user experience is improved. When the room has reached the set point, the tuyere is switched to state 2 in table 1 above. One air port is the air outlet, and one air port is the return air inlet to can effectively maintain current indoor temperature, ensure user's experience.
The invention is not limited to only using two air ports in each room, and the number of the air ports can be increased. Table 2 is a tuyere state extension table.
TABLE 2
As shown in table 2, when the number of the room air ports is n, the control logic is substantially identical to that of the 2 air ports. The difference is that when the number n of the air ports is even, the air port state 2 is that the air outlet and the return air port respectively account for half n/2, and the number of the air outlets is 50%. When the number n of the air outlets is odd, the number of the air outlets is (n +1)/2, namely the number of the air outlets is approximately equal to 50%.
