Prodotti

I-CHILL DESIGN is an advanced software for product design and selection in the HVAC, data center, refrigeration, and industrial process sectors (such as Chillers, Heat Pumps, Multifunctional Units).

​

It is an evolutionary-type tool developed to revolutionize the traditional design workflow. 

​

Unlike competitor software, which mainly works as a verification tool requiring users to preselect all components, I-CHILL implements a reverse and predictive methodology. 

​

Starting from desired performance and dimensional goals (cooling capacity, efficiency, footprint), the system uses optimization algorithms and an integrated component database to automatically generate, within seconds, a range of technically valid and optimized configurations. 

​

I-CHILL DESIGN is dedicated to HVAC engineering and R&D, applying an algorithmic, goal-oriented design approach. 

GOAL ORIENTED DESIGN

The system is based on a centralized relational database that serves as a single source of truth for all company departments.

The architecture has three main layers: 

​

• Calculation Layer (Engine): The core of the software, containing thermal balance and optimization algorithms. 

​

• Component Database: A large, hierarchical database containing mathematical models and performance data for compressors, heat exchangers (evaporators, condensers), fans, expansion valves, and other components. 

​

• User Interface (UI): An intuitive dashboard guides the user in defining specifications and displays generated solutions.

Architecture and Data Flow 

The ENGINE is the heart of I-CHILL DESIGN, known for rigor, speed, and precision. 

Heat Exchanger Methodology: 
Heat exchangers are modeled using a multi-zone infinitesimal approach

(NTU-ε method and local balances). The refrigerant path is divided into many

finite intervals.

​

For each, the software solves a system of equations including: 

• Energy balance and conservation equations 

• Mass balance equations 

• Heat transfer equations (rigorous calculation of convective coefficients

• for subcooled liquid, two-phase, and superheated vapor regions) 

• Pressure drop equations 

​

Refrigerant thermodynamic and transport properties are calculated in real time for each local condition using integrated reference libraries (CoolProp). 

​

Fan Management: 
The model includes the fan P-Q performance curve. The software determines

the optimal operating point, adjusting airflow (or frequency for inverter fans)

to balance heat transfer and absorbed power, maximizing seasonal efficiency.

Compressor Models: 
The database includes full multidimensional performance maps for compressors (hermetic, semi-hermetic, rotary, scroll, screw, Turbocor). For inverter and Turbocor compressors, the algorithm optimizes and selects the best operating frequency to reach the required thermodynamic point while minimizing specific energy and maximizing efficiency. 

​

Expansion Valve Calculation: 
Refrigerant mass flow and nominal power required for the valve are calculated using correlations such as m˙=CvΔp·ρ, ensuring target superheat both at design and off-design conditions. 

Calculation Engine (ENGINE)

SALES Users (I-CHILL SELECTION): 

• Accessory List: Automatically proposes compatible standard accessories (control panels, hydraulic kits, etc.) with pricing options. 

• AI-Generated Descriptions: AI analyzes the configuration and generates detailed technical-commercial descriptions, editable and customizable. 

• Catalog Creation: Export configuration, renderings, and specs in catalog/technical datasheet formats. An optional app allows strong customization of product description and graphics. 

​

Engineering Users (I-CHILL Engineering Hub): 

• Attach final dimensional drawings (2D/3D) and electrical diagrams to unit records. 

• Define the machine’s operating envelope (temperature interaction limits of working fluids). 

​

Marketing Users (Approval): 

• Marketing/sales management can review and formally approve units for release to the sales network. 

​

I-CHILL SELECTION: 
Fully integrated with DESIGN. Sales users can query approved units, filtering by performance, dimensions, and features, to quickly find the right unit for a specific application without redesign.

Integration with Company Departments (Platform Module)

Project Input (simplified and goal-focused): 

​

• Load Conditions: Flow rates, inlet/outlet temperatures for process fluids (water/glycol side) and condensation fluid (air/water side). 

​

• Performance Targets: Required cooling capacity (kW), efficiency targets (e.g., COP, IPLV). 

​

• Design Constraints: Coil face velocity, refrigerant type, ambient operating temperature range. 

​

• Machine Type: General configuration (air-to-water, water-to-water, etc.), type of compressor, heat exchanger, and fan to use. 

Functional Specifications of the Design Module 

Any automatically generated configuration can be manually modified by the designer: 

​

• Replace a component with another compatible one from the database 

• Modify operational parameters (fan speed, subcooling/superheating setpoints, etc.) 

• Update boundary conditions and recalculate performance

Editing Mode

For each configuration, the software generates a detailed report including: 

​

• Thermodynamic Report: Full technical operating data — cooling/heating performance, flow rates, pressure drops, evaporation and condensation temperatures/pressures, fan airflow. Data are compliant with EUROVENT, ERP, AHRI standards. 

​

• Component Data: Model/brand of compressor (with frequency if applicable), heat exchanger data (surface area, number of circuits), fan details (flow, static pressure, absorbed power), expansion valve specs. 

​

• Performance Indicators: Cooling capacity, absorbed power, EER, COP, SEER, SCOP, SEPR, IPLV, NPLV, controllability, flow rates, losses, electrical data, etc. 

​

• Dimensional Estimate: Approximate footprint and weight. 

​

• Advanced Energy Calculations: Automatic calculation of efficiency indices (AHRI, ISO) including SEER, SCOP, SEPR, IPLV, NPLV, based on user-defined load curves. The Energy Analysis tool also evaluates product efficiency according to installation

Output – Reporting and Visualization

I-CHILL DESIGN runs on MS Azure or Amazon servers, with access controlled by administrator-defined user profiles. Authentication and authorization use differentiated roles (Designer, Engineer, Sales, Admin, etc.). 

System Requirements

I-CHILL DESIGN represents an evolutionary leap in chiller design, shifting the focus from manual verification to automated goal-driven optimization. Its integrated architecture and shared database create a digital ecosystem connecting design, engineering, sales, and marketing, drastically reducing time-to-market while maximizing efficiency and product optimization.
