测试Adjusting and Balancing of HVAC Systems
The key to a comfortable and efficient space is the design and function of a building’s HVAC systems. The testing, adjusting, and balancing (TAB) of the systems is what ensures they are functioning properly. Using the right instruments for the TAB process is fundamental to making the right adjustments, in order to achieve a productive system.
The verification of an HVAC system’s design, installation, and TAB process is the commissioning of a system. The tools used to do TAB and commissioning work are just as important as the education and experience of the professionals performing the work.
Ways to measure and control ventilation systems and indoor air quality (IAQ) is crucial for architects, engineers, testing, adjusting & balancing (TAB) companies, contractors and installers, commissioning agents, and facility professionals to help meet goals for occupant comfort, energy efficiency, contamination control, risk management and more.
Essential TAB & Commissioning Instruments
- Capture Hoods– for measuring air flow and volume from diffusers and into return registers
- Rotating Vane Anemometers- 用于快速测量整个设施的气流和草稿
- Micromanometers– for measuring duct static, total and velocity pressures, pressure drops across filters, coils, fans, diffusers, differential pressure between rooms
- Hydronic Manometers– for balancing water-based heating and cooling systems
- Thermal Anemometers– used to do a duct traverse for balancing air-based heating and cooling systems
- 室内空气质量仪表– often used by TAB and commissioning professionals to detect and measure air quality in a space
Key aspects to consider when purchasing
- Accuracy– it is important for any measurement to be accurate, so check the specifications to see if the instrument meets standards and requirements for you area
- Durability– these instruments are used in a variety of environments and need to be able to withstand the elements and everyday use on the job
- Versatility– TAB and commissioning work often involves taking a variety of measurements and dealing with an assortment of situations. It is important for your instruments to be dynamic and help you complete the job without having to get a different instrument
- Support– After-sales technical, service and calibration support from an Australian based company with factory-trained technicians
