Description

Technical Field

[0001] This application relates to the field of air conditioning control technology, and in particular to an air conditioning control cabinet with air volume control function. Background Technology

[0002] Air conditioning control cabinets typically control central air conditioning systems by collecting signals from the main and auxiliary systems and the changes in terminal loads. They are widely used in large venues such as hotels, restaurants, office buildings, stadiums, libraries, and factories where central air conditioning is installed.

[0003] Currently, air conditioner fan control is generally based on a fixed speed, not a constant air volume. When external resistance changes, the air volume will be affected, thus impacting the actual user experience. Utility Model Content

[0004] One of the objectives of this application is to provide an air conditioning control cabinet with air volume control function to provide a constant air volume.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: an air conditioning control cabinet with air volume control function, including a driver, a control module and a touch screen, wherein the control module is provided with an air volume detection module, and the control module is electrically connected to the air volume sensor in the air conditioning unit through the air volume detection I / O port, and the control module is provided with a drive control module, and the control module is electrically connected to the driver through the drive control I / O output port.

[0006] Preferably, a current detection module is installed inside the driver.

[0007] Preferably, the control module includes a motor temperature detection module, which is electrically connected to a temperature sensor in the air conditioning unit.

[0008] Preferably, it also includes a communication module and external control feedback status points to facilitate flexible integration with third-party systems.

[0009] Preferably, the touchscreen is electrically connected to the communication module.

[0010] Compared with the prior art, the beneficial effects of this application are as follows:

[0011] In this invention, the control module connects to the airflow sensor in the air conditioning unit via an airflow detection I / O port. Based on the set airflow value, it automatically calculates a control value and connects to the driver via a drive control I / O output port to control the fan speed to achieve a constant airflow in real time. The driver is equipped with a current detection module and a motor temperature detection module to monitor the motor current and temperature in real time, providing dual protection for the motor. The control cabinet is equipped with a communication module and external control feedback status points for flexible integration with third-party systems. Attached Figure Description
