Precision thermodynamic modeling tool: automatically calculates required refrigeration cooling capacity (kW / HP), suggests optimal compressor packages, panel insulation thickness, and turnkey budget projections with 98% accuracy.
Compliant with ASHRAE Refrigeration Handbook & TCVN Standards
Total heat load (Q_total) follows international ASHRAE standards comprising 5 core components: Q1 (Transmission heat through walls, ceiling, and floor), Q2 (Product cooling and freezing heat load), Q3 (Air infiltration through door openings), Q4 (Internal operational heat from fans, defrosting, lighting, and personnel), and Q5 (Respiration heat for fresh agricultural produce).
For chill rooms (+2°C to +8°C), standard PU/PIR panel thickness is 75mm – 100mm (density 40-42 kg/m³). For frozen storage (-18°C to -25°C), 125mm – 150mm is recommended. For deep blast freezers (-35°C to -45°C), 175mm – 200mm high-density panel with airtight camlocks is mandatory to eliminate thermal bridging.
Our online calculator operates on proven empirical algorithms refined across 20+ years of industrial EPC projects, delivering 90% – 95% accuracy benchmarked against specialized software like Bitzer Software and Danfoss Coolselector2.
