Abstract
Description
Technical Field
[0001] This utility model relates to the field of static pressure box technology, specifically to an air supply static pressure box with an induction structure. Background Technology
[0002] A plenum chamber is an essential component in an air supply system that reduces dynamic pressure, increases static pressure, stabilizes airflow, and reduces airflow vibration, thereby improving the air supply effect.
[0003] A variable air volume (VAV) system is an all-air conditioning system that maintains a constant supply air temperature and automatically adjusts the air volume of the air conditioning system according to changes in indoor load or required indoor parameters, so that the indoor parameters meet the requirements. By keeping the supply air constant, it adapts to load changes by changing the air volume. The system needs to detect the actual room temperature and compare it with the set temperature before it can adjust the air volume according to the control logic to maintain a constant room temperature.
[0004] However, as Figure 4 As shown, when installing temperature sensor 8 in a room, it is usually installed on the wall or ceiling. Since the traditional static pressure box 1 is only a square cavity structure, it is necessary to connect signal lines to connect temperature sensor 8 to electrical control box 7 located in static pressure box 1 above the ceiling to receive temperature signal feedback from temperature sensor 8. However, this installation method can easily damage the decoration effect, increase on-site installation time, is inconvenient, unsightly, and does not save time, and cannot realize the detection of indoor temperature in static pressure box. Utility Model Content
[0005] The technical problem to be solved by this utility model is to provide a static pressure box with an induction structure, which can install a temperature sensor inside the static pressure box and detect the indoor temperature, reducing wiring and installation operations.
[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows.
[0007] A static pressure box with an induction structure includes a static pressure box connected to an air supply system via an air inlet cylinder. A nozzle is installed inside the static pressure box to discharge air from it. An induction chamber is located on the right side of the static pressure box, facilitating the installation of a temperature sensor to detect indoor air temperature within the box. An induction chamber inlet is located at the bottom of the induction chamber, drawing indoor air into it for temperature sensor detection. An induction chamber outlet is located at the top of the induction chamber, communicating with the nozzle.
[0008] In the aforementioned air-supplying static pressure box with an induction structure, the nozzle is located on the upper part of the static pressure box near the induction chamber, and the bottom surface of the nozzle is inclined upwards.
[0009] In the aforementioned air-supplying static pressure box with an induction structure, the temperature sensor is installed in the lower part of the induction chamber and near the air inlet of the induction chamber. The temperature sensor is connected to an electrical control box located inside the static pressure box via a connection signal line, and the input terminal of the electrical control box is connected to the output terminal of the temperature sensor.
[0010] The technological advancements achieved by this utility model are as follows, due to the adoption of the above technical solutions.
[0011] This utility model provides a static pressure box with an induction structure. By setting an induction chamber inside the static pressure box, and using nozzles to spray airflow to induce a low-pressure environment in the induction chamber, indoor air is drawn into the induction chamber. At the same time, a temperature sensor is installed inside the induction chamber to facilitate the detection of indoor temperature. This allows for the detection of indoor temperature inside the static pressure box, eliminating the need to install temperature sensors on indoor walls or ceilings, reducing wiring operations, and avoiding damage to the decoration effect.

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0018] A type of air supply static pressure box with an induction structure, such as Figures 1 to 3 As shown, it includes a static pressure box 1 connected to the air supply system via an air inlet cylinder 2. An induction chamber 4 is provided on the right side of the static pressure box 1. A temperature sensor 8 for detecting indoor temperature is installed in the induction chamber 4. An induction chamber air inlet 5 is provided at the bottom of the induction chamber 4, which can draw indoor air into the induction chamber 4 under low pressure, so that the temperature sensor 8 can detect the indoor temperature.
[0019] The top of the induction chamber 4 is provided with an induction chamber air outlet 6, and a nozzle 3 is provided on the top side of the static pressure box 1 near the induction chamber 4. The nozzle 3 is connected to the induction chamber air outlet 6 and can discharge the air in the static pressure box 1 through the nozzle 3.
[0020] The bottom surface of nozzle 3 is tilted upwards, which can guide the gas in static pressure box 1 and facilitate the discharge of air.
[0021] Temperature sensor 8 is installed at the lower part of induction chamber 4 and near air inlet 5 of induction chamber. Temperature sensor 8 is connected to electrical control box 7 located in static pressure box 1 via a connection signal line. The input end of electrical control box 7 is connected to the output end of temperature sensor 8 to facilitate receiving temperature signal feedback from temperature sensor 8.
[0022] The working principle of this utility model is as follows:
[0023] When primary air enters the static pressure box 1 from the air inlet cylinder 2, the air inside the static pressure box 1 forms a positive pressure, causing the air to be ejected from the nozzle 3. The air in the nozzle 3 will also be ejected from the air outlet 6 of the induction chamber 4 through the induction chamber 4, thereby creating a low-pressure environment in the induction chamber 4. This induces indoor air to be drawn into the induction chamber 4 from the air inlet 5 of the induction chamber and passes through the temperature sensor 8, thereby detecting the actual room temperature value.
[0024] This utility model provides a static pressure box with an induction structure. By setting an induction chamber inside the static pressure box, and using nozzles to spray airflow to induce a low-pressure environment in the induction chamber, indoor air is drawn into the induction chamber. At the same time, a temperature sensor is installed inside the induction chamber to facilitate the detection of indoor temperature. This allows for the detection of indoor temperature inside the static pressure box, eliminating the need to install temperature sensors on indoor walls or ceilings, reducing wiring operations, and avoiding damage to the decoration effect.
