Technical Field

[0001] This utility model relates to the field of energy-saving control technology for air conditioning systems, and in particular to an integrated energy-saving control device for air conditioning air supply. Background Technology

[0002] Traditional central air conditioning systems continuously supply air, leading to energy waste in unoccupied areas. Manual control is difficult and has a slow response time. Furthermore, the electric dampers in traditional systems are installed on ducts within the ceiling, often at a considerable distance from the air vents, making conventional energy-saving retrofits and wiring connections complex and difficult to implement. Therefore, a highly integrated, time-controlled automatic energy-saving device needs to be developed to solve the problem of separate installation of electric dampers, air vents, and microwave radar.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0034] Please see Figure 1-4 This utility model discloses an integrated energy-saving control device for air conditioning air supply, comprising:

[0035] The microwave radar induction switch 1 has a built-in delay control module 11 for real-time detection of human activity signals within a set area and triggers a delay disconnection command after the signal disappears. Preferably, the microwave radar induction switch 1 outputs a high level immediately when it detects a human activity signal, and switches to a low level after a set delay after the signal disappears. The operating frequency is 5.8GHz or 24GHz, and the detection distance is 8 meters. Furthermore, the delay time of the delay control module 11 of the microwave radar induction switch 1 is adjustable, with an adjustment range of 30 seconds to 20 minutes.

[0036] Intermediate relay 2 is wired to the microwave radar induction switch 1. According to the energized and de-energized state of the microwave radar induction switch 1, the circuit on / off signal is changed. Preferably, the coil voltage of intermediate relay 2 is AC220V, the contact load is AC220V / 5A, and the radar signal is received to control the circuit on / off. The intermediate relay 2 can be a small AC220 relay.

[0037] The electric air valve 3 is controlled by the on / off signal of the intermediate relay 2 to open or close the air supply channel of the air conditioner. Specifically, the electric air valve 3 is a normally open butterfly valve with an engineering plastic valve body. It automatically closes to cut off the airflow when the power is off, and the opening torque is ≤5N·m. The electric air valve 3 model can be an electric butterfly valve DN160.

[0038] The static pressure box 4 integrates the microwave radar induction switch 1, intermediate relay 2, and electric air valve 3 into a single unit. The static pressure box 4 includes an adapter interface 41, which can be a flange, for connecting the electric air valve 3 and forming an airflow passage. The static pressure box 4 also includes a flow equalization plate 42 for more evenly distributing the airflow within the static pressure box 4. In a preferred embodiment, the static pressure box 4 is made of engineering plastic. The static pressure box adapter interface 41 can be a hole or a standard flange. The flow equalization plate 42 achieves even airflow distribution through rectangular airflow slots. Figure 4 As shown, it should also be added that the size of the static pressure box should be adjusted according to the actual situation. When the static pressure box is long or the air volume is large, electric air valves and connecting pipes can be added to ensure the air volume, air uniformity and reduce the wind speed.

[0039] Connect pipe 5, connect electric air valve 3 and static pressure box 4 to form air conditioning air supply channel;

[0040] The damper support 6 is mounted on the connecting pipe 5 and is used to support the electric damper 3;

[0041] The universal support plate 7 is movably mounted on the air valve support 6 and is used to fix the microwave radar induction switch 1 and the intermediate relay 2. It can also adjust the radar scanning direction of the microwave radar induction switch 1. It should be explained in detail that the universal support plate 7 is used to fix the microwave radar induction switch 1 and the intermediate relay 2. The universal support plate 7 is provided with a circular ball head on the side near the air valve support 6. The air valve support 6 is provided with holes corresponding to the circular ball head to adjust the radar scanning direction of the microwave radar induction switch 1. In order to ensure that the direction of the universal support plate 7 is fixed after adjustment, damping is also provided in the holes on the air valve support 6 to maintain the direction of the microwave radar induction switch 1 after adjustment.

[0042] It should be noted that, in order not to affect the detection effect of the microwave radar, the static pressure box, flow equalization plate, air valve support, and universal support plate are made of engineering plastic.

[0043] Furthermore, the delay control module 11 achieves delay adjustment through an adjustable resistor or a digital DIP switch.

[0044] Furthermore, the detection direction of the microwave radar induction switch 1 is arranged perpendicular to the air supply direction of the electric air valve 3.

[0045] It should be explained in detail that the electric air valve 3 is controlled by the normally closed contact of the intermediate relay 2 to be in the normally closed state and by the normally open contact to be in the open state. When the microwave radar induction switch 1 detects a human activity signal, the output circuit is energized to de-energize the normally closed contact of the intermediate relay 2 and energize the normally open contact to control the electric air valve 3 to be in the open state.

[0046] It should be added that the implementation steps of this application include the following steps:

[0047] S1: Microwave radar sensor switch 1 scans the set area in real time. When human activity is detected, it outputs a high-level signal.

[0048] S2: After receiving a high-level signal, the coil of intermediate relay 2 is energized, the normally closed contact is de-energized and the normally open contact is energized, sending an opening command to electric air valve 3.

[0049] S3: Electric air valve 3 is energized and opened, connecting the air conditioning supply channel;

[0050] S4: After the human activity signal disappears, the microwave radar sensor switch 1 starts the countdown of the built-in delay control module 11;

[0051] S5: When the countdown ends, microwave radar sensor switch 1 switches to a low-level signal;

[0052] S6: After the coil of intermediate relay 2 is de-energized, the normally open contact is de-energized and the normally closed contact is energized, the electric air valve 3 is closed, and the air supply channel is cut off.

[0053] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0054] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0055] Additionally, "multiple" refers to two or more.

[0056] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
