4M FINE: How to Design and Calculate HVAC Systems with the 4MCAD Engine

What is 4M FINE and why you should use it for your HVAC projects

4M FINE is a software package for HVAC design and calculation, based on the BIM (Building Information Modeling) technology and the 4MCAD engine. It allows the user to design and calculate HVAC installations in a fully integrated environment, with automatic generation of drawings, reports, and bills of quantities.

4M FINE is the ultimate choice for HVAC professionals, as it offers a number of advantages over other software packages, such as:

  • It is fully autonomous, with a built-in CAD environment that has features and behavior similar to AutoCAD and 100% compatibility with DWG and IFC files.

  • It is smart, as it can "think", "suggest" and perform designs and calculations automatically, producing the complete HVAC project with all the drawings in their final form.

  • It is innovative, as it uses the BIM technology to create a 3D model of the building and the HVAC systems, with all the relevant information attached to each element.

  • It is reliable, as it has a rich and proven methodological background, based on international standards and regulations.

  • It is affordable, as it has competitive prices and flexible licensing options.

In this article, we will show you how to use 4M FINE to design and calculate a typical HVAC project in a few easy steps.

Step 1: Create the building model

The first step is to create the building model, either by importing it from an existing DWG or IFC file, or by drawing it from scratch using the powerful CAD tools of 4M FINE. You can also use the IDEA architectural package, which is fully integrated with 4M FINE, to create the building model with more advanced features.

Once you have the building model, you can define the thermal zones, the orientation, the climate data, and the thermal properties of the building elements. You can also assign occupancy schedules, internal gains, ventilation rates, and other parameters that affect the thermal loads of each zone.

Step 2: Design the HVAC systems

The next step is to design the HVAC systems for each zone. You can choose from a variety of systems, such as split units, fan coils, VRFs, chillers, boilers, heat pumps, air handling units, etc. You can also select the equipment from a comprehensive library of manufacturers' catalogs, or enter your own custom data.

Then you can draw the ducts and pipes that connect the equipment to the terminals (diffusers, grilles, radiators, etc.) using smart objects that automatically snap to each other and adjust their dimensions according to the flow rates. You can also insert fittings, valves, dampers, filters, pumps, fans, and other accessories from a rich library of components.

Step 3: Calculate the HVAC systems

The final step is to calculate the HVAC systems using the advanced algorithms of 4M FINE. You can perform various types of calculations, such as:

  • Thermal load calculations according to ASHRAE or EN standards.

  • Cooling and heating capacity calculations for each equipment.

  • Air flow calculations for each duct segment and terminal.

  • Water flow calculations for each pipe segment and terminal.

  • Pressure drop calculations for ducts and pipes.
