Ref Tools

Ref Tools: The Essential Mobile Toolkit for HVACR Professionals

Ref Tools is a comprehensive mobile application designed specifically for heating, ventilation, air conditioning, and refrigeration (HVACR) technicians. This free, robust suite consolidates critical diagnostic and reference instruments into a single digital platform, eliminating the need for multiple physical tools and manuals on the job. Professionals use Ref Tools to quickly calculate key values, diagnose system issues, order parts, and access vital technical data, directly from their smartphone, streamlining service calls and improving on-site efficiency.

Navigating the Refrigerant Slider

The Refrigerant Slider is a core component of Ref Tools, allowing technicians to perform rapid pressure-temperature calculations. Users select from a database of over 80 refrigerants, input a known pressure or temperature value, and the tool instantly calculates the corresponding metric. This function is vital for diagnosing system charges and verifying operating conditions. The calculations, based on advanced curve-fitting models, provide both dew and bubble points for refrigerants with glide, delivering essential data for accurate system analysis directly within Ref Tools.

Diagnosing with the Magnetic Tool

This feature of Ref Tools transforms a smartphone into a diagnostic instrument for solenoid valve coils. To use it, a technician simply places their phone near the coil. The built-in magnetometer detects the magnetic field, and the app indicates whether the coil is energized or not. This non-invasive test allows for quick troubleshooting of electrical issues without disassembling components, saving significant time during a service call. It is one of the many practical instruments bundled into Ref Tools.

Utilizing the System Troubleshooter

When faced with a malfunctioning system, technicians turn to the Troubleshooter in Ref Tools. The user navigates through a logical tree of common symptoms, such as insufficient cooling or abnormal noises. By selecting the observed issues, the tool provides a list of potential causes and recommended corrective actions. This guided diagnostic approach helps methodically isolate problems and suggests solutions, making Ref Tools an invaluable assistant for both novice and experienced technicians.

Sourcing Components via Spare Parts

Ref Tools integrates a direct link to Danfoss’s extensive parts catalog. Users can search for specific spare parts and service kits by product code or application directly within the app. After locating the correct component, its specifications, documentation, and visuals are readily available. The functionality within Ref Tools can also facilitate the ordering process, ensuring technicians have access to genuine parts to complete their repairs efficiently and correctly.

Planning Retrofits with the Low-GWP Tool

This function assists in planning system retrofits to more environmentally friendly refrigerants. A user selects a current refrigerant and a potential low-global warming potential (GWP) alternative. Ref Tools then analyzes the compatibility with thermal expansion valves (TXVs), providing crucial data to ensure a successful and efficient conversion. This helps technicians adhere to environmental regulations and make informed decisions on sustainable refrigerants, all through Ref Tools.

Optimizing Systems with the TXV Superheat Tuner

This specialized tool guides a technician through optimizing a thermal expansion valve’s superheat setting. The user inputs specific system parameters, such as valve type and current superheat readings. Using advanced algorithms, Ref Tools then provides valve-specific adjustment recommendations. The process, designed to be completed in under 15 minutes, helps fine-tune system performance for maximum efficiency and cost savings, showcasing the practical precision of Ref Tools.

Accessing Information with the Product Finder

The Product Finder in Ref Tools acts as a centralized database for technical product information. Technicians search by product code or browse by category to instantly pull up detailed specifications, technical documentation, wiring diagrams, and product images. This immediate access to information eliminates guesswork and delays on-site. Furthermore, details can be easily shared with clients or colleagues directly from the app, making Ref Tools a powerful information hub.
