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.

Refrigeration and VAC measurement – the essential tools to get you through the summer

The heating season may be over for the time being (providing we get more sunshine – this is the UK after all!) but good weather also spells an increase in demand for ventilation, air conditioning and refrigeration maintenance.

This week is shaping up nicely in terms of sunshine, and if forecasts are to be believed, there’s more hot weather to come this weekend. In these conditions many of us rely on our building air conditioning and cooling systems to get us through the day.

Luckily testo have just the instruments to make sure the temperature and working conditions stay comfortable. Here’s a round up of testo’s tools to help keep you cool and get you through the summer months:

 

Refrigeration Measurement & Analysis

Our range of refrigeration instruments feature the latest technology to help you to work smarter and more efficiently than ever.

 

Manifolds

Now with 60 refrigerant profiles and the added functionality of leak tests, Testo digital manifolds really are the perfect tool for every job. With the introduction of the new range, no matter your budget or requirements, Testo will have a solution.

Testo’s new Digital manifolds incorporate both the price advantage formerly associated with analogue measurement, and the undeniable precision that only digital equipment can offer.

VAC

In order to feel comfortable in a room, particularly during the summer months, correct ventilation and air quality is crucial. Testo offer a wide range of instruments for Ventilation and Air Conditioning Engineers in order to optimise the building climate.

 

Vane anemometers

Our best selling anemometer is the compact testo 417 anemometer kit. With built-in flow/temperature vane Ø 100 mm to measure flow speed, volume flow and temperature, it is perfect for the majority of applications regarding measurement of volume flow.

Accurate volume flow calculation thanks to easy input of duct area. In addition, it is easy to switch to the current temperature reading. The flow direction, i.e. drawn in or blowing, is visible in the display. Timed and multi-point mean calculation provide information on mean volume flow, flow speed and temperature readings.

Volume Flow Hood

Testo’s new volume flow hood testo 420 is the light, precise and convenient solution for regulating volume flows at larger air intakes and outlets. At swirl outlets in particular, the flow straightener significantly reduces the usual measurement errors. This allows users to fulfil hygienic Indoor Air Quality guidelines and stipulations in ventilation and air conditioning systems quickly and precisely, e.g. in industry, office rooms or in cleanrooms.

Handling is especially easy with a uniquely low weight of less than 2.9 kg and ergonomic handles. The measuring instrument can be tilted and removed for more comfortable readout of the measurement values. In addition to this, mobile devices can be used via Bluetooth App integration as a second display and remote control. Users can use the App to finalise and send the measurement report directly on site.

What are the dangers of HVAC pressure? Everything you need to know

It’s no secret that HVAC and refrigeration systems are complicated pieces of equipment. But with the right technology and a bit of know-how, it’s easier than you’d think to have them running safely and efficiently.

There are a number of process occurring inside these machines all at once, with temperatures and pressures contributing to their functionality. If either of these functions develop issues, it can compromise the effectiveness of the unit, or create a dangerous work environment.

With the right support HVAC systems don’t pose as many problems as they used to

 

The following examples outline the potential dangers of incorrect pressure readings, and possible causes for these problems.

 

What dangers do incorrect pressures pose?

HVAC and refrigeration units are designed with certain operating conditions in mind, and the parts that comprise them will all have a specific set of tolerances to ensure they don’t fail. While most units will have a cut-off that detects dangerous pressures, these instances still pose a threat to its functionality.

HVAC Web Tech states high pressure within these units could cause the internal cylinder to rupture, rendering it useless. In extreme cases, this can create further problems if the pressure is great enough to release the refrigerant at force.

In such an event the force can even cause damage to nearby workers or other machinery. The organisation advises that any personnel working with faulty units should be wearing the necessary protective clothing in case high pressures overload them.

 

How is high pressure caused?

Due to the complicated nature of these units, there are a number of reasons for pressures to become too high or too low. One possible cause, which is relatively simple to diagnose is an overcharged refrigerant. Put simply, this means there is too much of the respective refrigerant in the system, which normally results in high pressure readings.

The amount of refrigerant in a system greatly affects its potential to function and contributes to low pressure measurements as well. If there is too little refrigerant in the unit, it will result in low pressure, preventing the machine from running at its best.

 

What will help to keep pressures in check?

testo-550-digital-refrigeration-manifold-bluetoothThe best way to ensure these conditions don’t endanger your HVAC unit is to schedule regular maintenance and ensure it is performed correctly. On top of this, any strange behaviours from the machine should prompt immediate inspection.

Devices such as the testo 550 Refrigeration gauge (pictured right) provide an easy way to inspect pressures in your HVAC and refrigeration equipment, with the digital display feeding accurate information that is right first time, every time.
