Commercial Refrigerator

Commercial refrigerators are large-capacity refrigeration units designed for businesses. They operate on the vapor-compression cycle (compressor, condenser, expansion, evaporator) like household fridges, but are built for continuous operation and larger loads
Examples include reach-in upright coolers, display cases, walk-in coolers/freezers, and under-counter units. They keep goods (food, beverages, pharmaceuticals) at safe temperatures for storage or display.

Type of Commercial Refrigerator

Vary by configuration: Reach-in cabinets (upright with hinged or sliding doors), undercounter/fridge drawers, chest freezers, and display cases (open-air or glass doors). Walk-in coolers and freezers are custom-built insulated rooms with refrigeration systems. Based on condenser type, they may be self-contained units (all refrigeration parts in one cabinet) or split systems (external condenser, ducted refrigerant). Refrigerant choice (commonly R-134a, R-404A, R-290, etc.) and insulation thickness are key design aspects.

Applications in Various Industries

Used in retail (supermarkets, convenience stores), food service (restaurants, bakeries, hotels), laboratories and hospitals (for specimens and drugs), and manufacturing (material storage). For instance, supermarket refrigeration racks and display freezers keep perishable foods cold. In India, commercial fridges are widespread in eateries and pharma cold chain.

Material Selection Considerations

Interiors are typically stainless steel or food-grade aluminum (for easy cleaning and hygiene). Exterior panels may be stainless or painted steel. Shelving is usually chrome-plated steel or aluminum. Insulation is polyurethane foam. Refrigeration coils are copper tubing, often aluminum-finned. Door gaskets are PVC rubber. Materials must balance durability (stainless exterior, heavy cast door hinges) and cost (ABS or laminate for some interiors).
