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.

How the food industry is taking advantage of automated monitoring to optimise working procedures and decrease workloads

When it comes to the food industry, no matter which area a company works in, food safety is always a major concern. The sheer scale of end-customer demand, coupled with strict time restraints, puts a huge amount of pressure on the food industry to ensure all produce is carefully monitored and regulated from farm to fork. Practically every point of the process, throughout production, preparation, storage and transport, has potential danger areas regarding spoilage through mismanagement or poor temperature regulation.

Monitoring temperature is a particularly important part of this process. Incorrect climatic conditions can have devastating consequences, and businesses often leave themselves at risk of incurring needless costs should there be a power cut, or system malfunction. This can lead to wasted stock or worse; a legal dispute.

Such costs can be detrimental to both production and reputation (should the tainted stock be distributed) and will ultimately have a negative effect on profit margins.

Within the food industry more and more businesses are opting to use automated temperature monitoring. For certain applications simply using a data logger and noting down readings manually is sufficient, for instance building monitoring where there is no danger of damage to stock and you simply need the records for reference purposes. When dealing with climate sensitive stock though, as is more often than not the case in the food industry, using an alarm fitted system which monitors conditions continuously is fast becoming a necessary requirement. With such a system in place, if there is a problem, you will be notified immediately, so you are able to react straight away, before it is too late. This is particularly useful if you don’t have staff on site 100% time, which let’s face it, most companies don’t the have resource for.

When first introduced, whilst the logic and practicality behind this type of solution is somewhat undeniable, systems were very costly and the quality manager or person responsible for food safety simply couldn’t justify the cost. This has often proved to be the stumbling block for companies looking to move to an automated system, instead sticking with more traditional temperature loggers, and taking manual readings. To an extent this is understandable, “if it’s not broken don’t fix it”, right? Admittedly, in the first instance investment is needed for such a system. In the long run, however, it will likely save the business valuable time and manpower.

For example, if in the current regime a member of staff is required to go around and take checks at numerous locations, this is a needless additional task which could be used for something more productive. And of course, as mentioned previously, the overriding advantage of employing such a system is to act as a contingency measure and protect your operation in the event of a problem or system malfunction. This could end up saving money in the long run, on wasted stock, potential product recalls etc. Another saying comes to mind: “But we’ve always done it that way”. This has been described as the 7 most expensive words for any business; failure to adopt new methodologies can hurt a business in the long run.

 

The above video explains the advantages of an automated temperature monitoring system

What’s more, as technology continues to advance at an astonishing rate, such systems are now becoming available for a fraction of the cost when this type of system first hit the market. Testo’s Saveris 2 for example offers a fully automated temperature monitoring system from under £100 with no additional costs for software. Therefore, it doesn’t cost as much as you’d think to ensure your peace of mind.

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.
