Much as a doctor performs tests to gather clues about a patient’s ailment, service technicians use tools and procedures to accurately pinpoint why an HVACR system will not function properly. The principles guiding these troubleshooting steps are universal, even if their implementation is not.
New demand is pushing for enhanced tool capabilities and functions. Both the HVACR installer and service technician are experiencing a need for these enhanced tools, and manufacturers are working to provide just that.
The Charlotte Mecklenburg School System (CMSS), the 19th largest in the U.S. with a $1.3 billion operating budget, recently decided to take action to identify school system buildings that might be exhibiting air leakage.
The TXV also simultaneously controls a set amount of evaporator superheat while, under these same conditions, assuming the range and capacity of the valve is not exceeded.
The device measures pressure, temperature, flow, and other parameters. Five different ranges are available from ±30 inches of water column to ±100 psi.
These ruggedized electrical meters can reach into cramped openings or crowded cabinets while providing an open-jaw design for current measurements and large-diameter cables up to 15.5-mm diameter.
With a wireless range of over 100 feet between the scale and the remote or smartphone, and compatibility with Job Link, technicians can quickly obtain the necessary measurements on the refrigerant.
Advancements in technology have brought a lot of opportunity to the tool market, with items like reporting, mobile apps, and wireless data transmission.
Ergonomics can be defined as the science of designing the job to fit the worker rather than physically forcing the worker’s body to fit the job. In the HVAC world, this means making tools as user-friendly to a technician’s body as possible.
