Application Frigoriste _verified_ Jun 2026

Why only 3.5 stars? Because the is too conservative. For a 30m R290 line at -10°C evaporating, the app insisted I needed a 1-1/8" line, which is overkill and economically stupid. Experienced fitters will know to override it, but a junior tech might waste money on copper. The Load Estimator for cold rooms is basic – it uses rough rules of thumb (e.g., 150 W/m³ for a frozen room). For a serious design, you still need CoolPack or a manual J-calculation. This module is good for a quick sanity check, not for final engineering.

The interface is clearly designed by engineers for engineers. Buttons are large enough for gloved fingers, and the text is crisp. However, the learning curve is steep. If you are a first-year apprentice, you will be lost. There is no "wizard" mode that explains why you need to enter liquid line length or ambient temperature. You either know what you’re doing or you don’t. I appreciate the lack of hand-holding, but a few embedded tooltips wouldn’t hurt.

This module turns your smartphone into a diagnostic co-pilot. You input suction pressure (from your manifold), suction line temperature (from a clamp probe), and liquid line data. The app instantly gives you target superheat based on indoor/outdoor conditions and actual superheat. application frigoriste

This is the weakest link, though still decent. The pipe sizing tool uses the standard ASHRAE pressure drop method (1K per 10m for suction lines). You enter refrigerant, capacity (kW/TR), equivalent length, and suction/discharge temperatures. It spits out recommended line sizes and even calculates oil return velocity.

In almost all "applications frigoristes," the Vapor Compression Cycle is used. Why only 3

These help with the "paperwork" side of being a frigoriste , such as intervention reports and legal compliance. : Customizable digital forms. Perfect for creating intervention reports on-site. Captures digital signatures from clients. CoolExpert (or similar ERPs) : Manages inventory, billing, and scheduling. Tracks refrigerant logs (essential for F-Gas compliance). 📐 Visualization: The Refrigeration Cycle

To understand what these apps are calculating, it helps to see the pressure-enthalpy (P-h) relationship. 📈 Key Features to Look For Experienced fitters will know to override it, but

Refrigeration is the process of moving heat from one location to another using mechanical energy. While the basic principles remain constant (thermodynamics), the applications have diversified significantly.
