## [Commissioning, Validation and Maintenance](/en-INT/applications/air-conditioning-and-ventilation/commissioning-validation-and-maintenance) ![Commissioning, Validation and Maintenance](/sites/default/files/entityone_paragraphs/images/Commissioning%2C-Validation-and-Maintenance_0.png) HVAC engineers are involved at various stages in the life of a ventilation system – starting with the commissioning phase, when system tuners check that all the components are designed, installed, tested and used in a way that meets the operational specifications set by the project managers and the customer. These vital checks ensure that the ventilation system operates as efficiently as possible right from the outset. Engineers will need to return to work on the ventilation system at regular intervals – from carrying out statutory inspections to servicing and maintaining the entire system. This process involves measuring all air parameters in order to detect even the slightest problem or defect, with clogged filters being the most common issue. Preventive maintenance can help to extend the lifespan of ventilation systems and components. Measuring pressure at air filters is especially important for preventing damage to fans and saving energy, since some modern ventilation systems are designed to increase power and maintain the same level of air flow when filters become clogged. Each of these tasks are easy to carry out wih premium, portable, measurement instruments. Sauermann instruments are quick and easy to use while catering to every professional requirement, saving engineers and technicians precious time and allowing them to focus on their core areas of expertise. > Measuring pressure at air filters is especially important for preventing damage to fans and saving energy. Multifunction ## Multifunction Commissioning and maintaining ventilation systems involves measuring a wide range of air parameters, from temperature, pressure, and air flow and velocity, to humidity, CO2 concentration and more. That’s why portable, multifunction instruments are the tool of choice for these tasks. Sauermann has extensive expertise in manufacturing premium measurement instruments. Our devices deliver the high degree of accuracy needed to test ventilation systems against the indoor air quality standards and recommendations that apply to residential, commercial, and industrial buildings. Sauermann’s portable, multifunction devices are some of the most advanced commissioning, testing, balancing and maintenance instruments on the market. And because they’re built for reliability, speed and user-friendliness, they help professionals work more efficiently. What’s more, their modular design and range of attachable probes lets engineers build a custom measurement solution – all calibrated in Sauermann’s in-house laboratories, which are accredited by COFRAC to ISO 17025:2017.

That’s why we designed the DBM 620 air flow meter specifically for this purpose: to easily calculate the ACR via the accompanying mobile app. Air flow readings play a key role in checking whether the ACR is high enough – and in keeping the system running as efficiently as possible. > “An air flow meter is the most versatile and effective portable instrument for measuring vent air flow.” Regularly replacing the air in a room – by bringing in a flow of filtered air from outside – is the most effective way to reduce concentrations of pollutants such as volatile organic compounds (VOCs), bacteria, viruses and dust. Measuring the ACR is therefore especially important in ensuring that the air inside a confined space is clean and healthy. An air flow meter is the most versatile and effective portable instrument for measuring air flow. It is compatible with all types of air vent – incoming and outgoing – and far outperforms other solutions when it comes to measurement accuracy.

They influence many other aspects of the ventilation chain, not least the heating and air conditioning settings. These two properties also have major implications for occupant health in commercial buildings, as well as affecting the lifespan of certain materials, which can be damaged by the growth of mould. That’s why it’s essential to measure temperature and humidity both inside the ventilation-system pipes and in the ambient air in occupied areas of a building. > “Temperature and humidity need to be tightly controlled in certain types of commercial premises, such as data centres.” Temperature and humidity need to be tightly controlled in certain types of commercial premises, such as data centres, as well as in main distribution frames, transformer rooms and other technical facilities.

Our thermo-anemometers are the perfect tool for this task, since they also provide air temperature readings that give a clearer picture of ventilation system performance. > Improved indoor air quality management and ventilation system efficiency gains. Measuring air flow is vital to effective indoor air quality management, since every aspect of the environmental conditions inside a building hinge on this parameter. Getting the air flow just right leads to improved indoor air quality management and ventilation system efficiency gains. It’s equally important to measure the air flow through outlet vents, in order to check that the air inside a room – which is loaded with CO2 , particles, chemical and biological compounds, and other pollutants – is being extracted effectively.

In fact, it’s a key indicator of the rate at which air is replenished in a room – the air change rate, or ACR – for several reasons: because CO2 concentration is highly responsive to changes in indoor atmospheric conditions, because it’s directly influenced by the number of people in a room (each of whom breathes out CO2 ), and because it’s quick and easy to measure. “Sauermann instruments use non-dispersive infrared (NDIR) CO2 sensors, the only kind of sensor that delivers dependable CO2 concentration readings.” But reliable measurements can only be obtained using premium, calibrated devices. That’s why Sauermann instruments use non-dispersive infrared (NDIR) CO2 sensors, the only kind of sensor that delivers dependable CO2 concentration readings. Our AQ 110 portable instrument is configured in the lab and certified to CO2 measurement regulations. As well as taking occasional readings, its internal memory can store recurring measurements, providing insights into changes in CO2 concentration as the number of occupants in a room fluctuates over the course of a day. These measurement campaigns allow the air flow from the ventilation system to be adjusted in line with target ACR values.
