HVAC (heating , Ventilation and Air conditioning) BLOG

Transporting temperature-sensitive goods across global supply chains is an intricate engineering challenge. A refrigerated vehicle (reefer) must maintain precise internal conditions while facing ambient temperature swings, dynamic road stress, door openings, and continuous thermal load demands. Key Pillars of Refrigerated Vehicle Design 1. Insulated Body & Composite Panel Technology The primary defense against heat ingress is the insulated cargo envelope. Modern reefer design relies heavily on polyurethane (PU) or polyisocyanurate (PIR) foam cores sandwiched between fiberglass-reinforced plastic (FRP) or aluminum skins. Thermal Conductivity (k-factor): Minimizing heat gain requires low thermal conductivity materials and optimal core thickness (typically 80 mm to 140 mm depending on deep-freeze requirements). Thermal Resistance (R-value): Wall performance is calculated as R = d / k, where d is material thickness and k is thermal conductivity. Vapor Barriers & Moisture Ingress:...
