In modern building management, the accuracy and intelligence of temperature control are directly related to the comfort of building users, energy consumption costs and management efficiency. With the rapid development of building automation technology, building management systems (BMS) have become the core of comprehensive management in large commercial buildings, hotels, hospitals and other places. As a key execution component of temperature control, thermostatic valves provide efficient and reliable solutions for building temperature automation management by virtue of their high compatibility with BMS systems, pushing building operation and maintenance into a new stage of intelligence.
Building temperature control needs upgrade, BMS system becomes core support
As people's requirements for the comfort of the building environment increase, as well as the urgent need to save energy and reduce consumption under the "double carbon" goal, the traditional temperature control method that relies on manual adjustment is no longer able to meet the management needs of modern buildings. Manual adjustment not only has the problems of delayed response and low temperature control accuracy, but also causes energy waste due to human operating errors - such as excessive operation of the air conditioning system, temperature imbalance in local areas, etc., which not only increases the operating cost of the building, but also reduces the user experience.
In this context, the BMS system came into being. As a comprehensive management platform integrating HVAC, water supply and drainage, electrical, security and other subsystems in the building, the BMS system can realize automated control and optimal dispatch of building equipment through real-time data collection, analysis and calculation. In the HVAC subsystem, the thermostatic valve is a core component that regulates pipeline media flow and controls indoor temperature. Its compatibility with the BMS system directly determines the intelligent level of building temperature management.
Deeply adapted to the BMS system to achieve precise linkage
As a global provider of industrial and building automation solutions, the temperature control valve products it develops are outstanding in terms of compatibility, stability and intelligence. They can be seamlessly connected with mainstream BMS systems (such as its own Desigo CC system and third-party building management platforms) to build a complete temperature management closed loop of "data collection - analysis and calculation - execution control".
From a technical perspective, in-depth adaptation to the BMS system is achieved through the following advantages: First, it has a standardized communication interface, supports mainstream industrial communication protocols such as Modbus and BACnet, and can quickly access the BMS system network to ensure real-time transmission of temperature data, valve operating status and other information, and avoid the "information island" problem caused by protocol incompatibility. Secondly, it is equipped with high-precision sensors and intelligent control chips, which can not only accurately collect data such as indoor temperature, pipeline medium temperature and pressure, but also adjust the valve opening in real time according to the control instructions issued by the BMS system. The temperature control accuracy can reach ±0.5°C, which is much higher than the adjustment effect of traditional manual temperature control valves, effectively avoiding the decrease in comfort caused by temperature fluctuations.
In addition, it also has an "adaptive adjustment" function. During the linkage process with the BMS system, it can automatically optimize the adjustment strategy based on the flow of people in the building and changes in outdoor environmental temperature (such as seasonal changes, day and night temperature differences).
Practical application value: reduce costs and increase efficiency, improve building operation and maintenance quality
In actual application scenarios, the collaborative work with the BMS system has brought significant value enhancement to building managers. Take a large commercial complex as an example. The complex previously used traditional temperature control methods, which caused problems such as high energy consumption of the air conditioning system, temperature imbalance in local areas (such as high-rise offices being too cold in summer and low-rise shops being overheated in winter), and high equipment maintenance costs. After introducing Siemens temperature control valves and connecting them to the BMS system, through real-time data monitoring and automatic adjustment, the complex's HVAC system energy consumption was reduced by 15%-20%, saving over one million yuan in electricity bills every year. At the same time, the temperature adjustment response speed was increased to the second level, and indoor temperature fluctuations were controlled within ±1°C, significantly improving the comfort and satisfaction of merchants and customers.
For places like hospitals that have high requirements for temperature control, the linkage between Siemens temperature control valves and BMS systems plays a key role. In the hospital's operating rooms, intensive care units (ICU), drug storage rooms and other areas, the temperature needs to be maintained within a specific range (for example, the operating room temperature needs to be stable at 22-25°C). The valve opening can be continuously fine-tuned based on the environmental data transmitted in real time by the BMS system to ensure that the temperature is always within a precise range, providing a stable environment for the safe development of medical activities.
