Worldwide the HVACR industry is witnessing growth in terms of warehousing, large buildings, malls, hospitals, commercial complexes, residential cooling and many more. The increase in overall climate temperature also mandates the establishment of better refrigeration systems in such facilities. And now when summer is around the corner, air conditioning and refrigeration has now become a part and parcel of everybody’s life. Yet, the stakes are very high as these systems consume close to half the connected electrical power and the entire efficiency of the system is dependent on the refrigeration cycle. Because of the expanding markets for refrigeration and air conditioning and changing technology, a dramatic need exists for technologically advanced air conditioning and refrigeration solutions.
To match the pace with this expanding industry where, on one hand efficient refrigeration set up is must but on the other hand it is even more important to regulate the energy usage by these systems, testo provides complete solutions for any VACR facility or system enabling energy conservation, efficient operation and reduced wastage.
Digital, not analog: One manifold for all refrigeration systems
Two main factors are crucial when it comes to the comprehensive evaluation and correct adjustment of refrigeration and air conditioning systems: The refrigerants supported by the manifold, and constantly precise measurement values. In both areas, digital refrigeration technology from Testo has for years proven its worth.
Progress and digitalisation can no longer be halted, and are changing the refrigeration sector too. The most important reasons are:
- Modern refrigeration and air conditioning systems are becoming more and more complex with better and better performance.
- New refrigerants are constantly being introduced, and old ones taken off the market.
- New legislation and regulations are changing the requirements regarding energy efficiency and environmental protection.
The measurement technology used for commissioning and servicing the plants must perform accordingly. The latest trends and advancements are coming from the digitisation of the working system. The traditional methods and processes are now getting replaced with smart solutions. All the time consuming, manually driven operations can now be governed with just a click of the smartphone making the process more easy, accurate, fast and reliable.
Digital manifold kits testo 550 and testo 557 – including filling hoses
These instruments are perfect for the complete servicing of heat pumps, air conditioning and refrigeration systems. The digital manifold kits testo 550 and testo 557 stand out, thanks to two clamp probes, a vacuum probe (testo 557 only), the robust case, and above all the respective filling hose set. Linked by Bluetooth to the testo refrigeration app, the manifolds now make work even easier. System parameters such as sub-cooling and superheating can be monitored from up to 20 metres via a smartphone or tablet. Sending a report by e-mail and automatic, free updates with new refrigerants are also among the strengths of the little digital helper for iOS and android.
Wifi Data Logger testo 160
The testo 160 wireless LAN data logger measures, monitors and documents temperature, humidity, light intensity, UV radiation and CO2 concentration in rooms, offices, malls or even inside display cases of exhibition rooms– automatically and without interruption – hence all indoor climate monitoring parameters in one. The loggers have small dimensions and especially, minimalistic design. And they have a ‘cloak of invisibility’. An individually designable cover is available for each data logger. This allows the little high-tech wonders to blend into almost any environment, and do not distract the viewer from the exhibits – for example in exhibition rooms. All measurement values are transferred by wireless LAN to the online database (Testo Cloud). From there, they can be called up by App or with a PC or tablet or smartphone and a normal browser at any time. If limit values are exceeded, an alarm is immediately provided by SMS and/or e-mail. That makes monitoring easy and data accessible anytime, anywhere on PC or tablet or smartphone.
The new testo Smart Probes AC & refrigeration test kit
Smart Probes are the unique solution for fast testing of heat pumps, air conditioning and refrigeration systems: Two high-pressure measuring instruments (testo 549i) and two clamp thermometers (testo 115i) are available in the new, testo Smart Probes HVAC soft case. This not only provides space for the four Smart Probes in the kit, but also has slots for six further Testo Smart Probes for other HVAC applications.
The testo Smart Probes AC&R test kit is supported entirely by the testo Smart Probes App. In addition to 80 refrigerants, intuitive menus are also stored for the automatic calculation of superheating or sub-cooling and evaporation or condensation temperature. Documentation with photos and comments can be carried out completely paper-free by e-mail protocol.
Intuitive air velocity and IAQ measurement: The new testo 440
Testo in its recent upgrade, combines everything which makes the air velocity and IAQ measurement technology so successful – intuitive operation, precise measurement values and an extensive probe range – and extends these advantages by wireless convenience. The testo 440 constitutes a compact handheld measuring instrument with user-friendly measurement menus and wireless probes – for the versatile and convenient measurement of all air conditioning and ventilation parameters. The testo 440 probes are available for air velocity, temperature, humidity, degree of turbulence, CO2, CO and light intensity. Customers have the choice between wireless and fixed-cable models. The wireless Bluetooth probes ensure more freedom of movement in measurement and save space in the measurement case. In addition to this, a probe handle can be universally combined with all corresponding probes and probe attachments. This allows the user to switch in seconds from indoor air quality measurement to a determination of volume flow at a vent. Testo 440 has extendable telescopic handle which gives an additional advantage in terms of accessibility and saves time. It also comes with a 90° angle connector for flow measurement which enables the user to take both vertical as well as inside the duct measurements very easily.
