All outlets – All flow velocities – One expert.

Install, inspect and service air conditioning and ventilation systems in ducts and at outlets

The correct and efficient adjustment of ventilation and air conditioning systems makes very high demands on measurement technology, due to various measurement locations and different flow velocities. Whether the precise determination of volume flow, quick spot measurements in ducts or the recording of turbulent flows at outlets: without suitable measuring instruments, it is impossible to ensure optimum indoor air quality in residential and non-residential buildings. Immediate effects of indoor air pollution often resemble those from a common cold or illness, making a potential issue even more difficult to detect. There are several illnesses that result from contaminated indoor air. Some of the more minor effects include irritated eyes, nose or skin as well as an increased likelihood of irritation of the eyes, coughing, headaches, dizziness, fatigue and nausea.

The most accurate measurement results can be achieved by measuring directly in a duct. However, since ventilation ducts are in practice frequently hidden or inaccessible, it is often necessary to resort to outlet measurements. In addition to this, turbulence in ducts and at outlets can often falsify measurements as well. These are just a few of the issues that engineers may encounter when carrying out precise flow velocity measurements.

 

Accurate and convenient measurement in ducts.

Ventilation and air conditioning systems are indispensable for indoor air quality; for them to function smoothly and efficiently, they must be tested regularly, and if necessary readjusted. If the air flows in ventilation ducts are smaller than intended, the removal of indoor loads (hot, cold and substance loads) can under certain circumstances not be guaranteed.

If the ventilation duct is accessible, duct measurement is the best solution. This is because air flows are measured most accurately directly in the duct. However, it must be considered that the flows in the duct are usually non-homogenous and turbulent. To obtain reliable results despite this, measurements should always be taken at several measuring points over the duct cross-section. In these grid measurements, a mean flow velocity is derived from the individual measurement values.

 

With the patented flow straighteners from Testo, even turbulent flows can be measured accurately.

 

The right ventilation measuring instruments support you in grid measurement just as reliably as in the automatic calculation of volume flow. Which instrument suits your application depends on the flow velocity range you wish to measure.

 

Precise measurement at outlets.

The quality of the indoor air depends crucially on whether the air input or output volume flows are optimally adjusted. For this reason, the measurement is taken directly at the outlet during adjustment work. However, inaccessible ventilation ducts also make measurements at outlets necessary. At swirl and plate outlets or ventilation grilles however, turbulence is created, which can falsify the measurement results and which are essential to consider.

To be able to measure these non-uniform flow profiles, it is essential that a funnel measuring instrument includes an integrated flow straightener that converts the turbulence into an almost uniform and easily measured air flow to guarantee the greatest level of accuracy, even in strong air turbulence.

Testo offers the optimum solution for every measurement task and measurement range: thermal probes, vane anemometers, differential pressure measuring instruments, funnel measuring instruments and multifunction measuring instruments. With the patented flow straighteners from Testo, even turbulent flows can be measured accurately. Testo’s free Apps make ventilation measurement also more convenient and less stressful than ever before.

Refrigeration system maintenance today’s way

Are you one of many service engineers still working with analog manifolds? If so, you will be all too familiar with the fact there are far too many instruments are used in refrigeration system maintenance. Depending on the refrigerant or task, you need additional pressure and temperature measuring instruments or even another manifold. This results in more expenditure, in addition to the laborious handling and the frequent inaccuracies of measurement.

But wouldn’t it be much more practical if you only needed one instrument for all the maintenance work? Testo’s smart measuring technology including Testo’s App-controlled manifolds and Smart Probes support you in every task to make your daily work more efficient than ever.

 

 

Clearly, digital manifolds are nothing new. However, you can finally use the tool which has already been enriching and simplifying your private life for years, at work too: your smartphone or tablet. In contrast to analogue solutions, Testo’s smart refrigeration technology turns your smartphone or tablet into an efficient all-round tool instead.

This means you can simply measure pressure and temperature values, carry out a temperature-compensated tightness test or get superheating and sub-cooling values automatically calculated and displayed in the App.

 

 

Whereas in the past data had been analysed by printing out the measurement protocol and laboriously saved on the PC, all measurement results can now, irrespective of the measuring location, be graphically displayed and immediately dispatched on site by email – whether to the office or to the customer. And you can also update and extend the list of the most common refrigerants stored on the instrument at any time via the App. That sounds like a smarter way of working, doesn’t it?

This change from analogue to smart measuring technology is particularly worthwhile in the refrigeration industry, because many different parameters, such as pressures and temperatures, along with the superheating and sub-cooling of systems, must be checked here. The App makes additional measuring instruments unnecessary, streamline your entire work process and save a lot of effort as well as loads of valuable time. With Testo, your day-to-day work finally becomes part of your own smart world too.

Thermal Imaging for contractors – advantages in a nutshell

For contactors in the Building, Facilities Maintenance, HVAC, and Electrical industries, the ability to visualise each situation you are facing can make a huge difference. Knowing precisely where to start with a job, can save time and effort, meaning you increase efficiency, and ultimately provide a faster service to customers.

Those 20-30 minutes extra spent diagnosing each job soon add up, particularly at busy times of the year when you’ve got a waiting list. With that in mind, a valuable addition to many contractors toolkit is a thermal imaging camera.

But what specific applications is a thermal camera most useful for?

Below we summarise some of the best examples where thermal imaging has time and time again, proved an extremely effective diagnostic tool for contractors:

 

Heating and installation systems

  • Checking radiators for build-up of silt deposits
  • Identifying underfloor heating abnormalities
