Building automation systems are an emerging technology that leverages communication, sensor, and computer technologies to achieve process monitoring of related equipment. Designing a comprehensive and open intelligent monitoring system is at the heart of building automation.

　　Our company’s PLC-based energy-saving control system enables monitoring, control, measurement, recording, archiving, and alarming of the operating conditions of HVAC equipment throughout an entire building—such as chillers, central air-conditioning units, fresh-air handling units, fan coil units—as well as equipment like pumps, valves, and sensors. This system achieves centralized management, distributed control, and energy savings while reducing energy consumption.

　　The PLC-based energy-saving control system can physically, logically, and functionally integrate the intelligent subsystems with different functions within a building, thereby achieving comprehensive information integration and data sharing.

　　An excellent and well-designed HVAC automatic control system not only needs to take into account the requirements of HVAC equipment for the automatic control system itself, but also must consider the actual conditions of the building, thereby identifying more optimized control and energy-saving solutions.

　　The Tianxing air-conditioning and automatic control system is mainly divided into the following components: 1. High-precision temperature and humidity control strategy for central air conditioning; 2. Safety protection strategy for central air conditioning; 3. Implementation planning for the automatic control scheme of air-conditioning units; 4. Planning for the cluster control function of refrigeration stations; 5. Architecture of the automatic control monitoring network.

In-sales service:

　　● Before the project starts, specialized engineers can be dispatched to the installation site to provide installation guidance to the construction personnel and promptly correct any issues that arise.

　　● After installation is complete, we will dispatch professional engineers to the installation site to perform commissioning, provide communication, answer questions, and resolve any issues that arise on-site until the desired results are achieved.

　　● During the acceptance phase, cooperate with the user to complete all types of acceptance documentation, fully prepare for the acceptance inspection, provide thorough answers to any questions, and ensure a smooth acceptance process.

　　● After the project is put into operation and passes acceptance, the organizing engineers will go to the site to provide training and guidance for management personnel.

After-sales service:

　　● Our company’s products come with a two-year warranty and lifetime maintenance.

　　●Our company has a dedicated after-sales service hotline that accepts comprehensive technical inquiries, quality complaints, and service requests from users on weekdays.

　　● After the warranty period expires, our company will provide paid maintenance services in case of product damage.
