The walk-in cooler/cold room is a large, accessible low-temperature storage device, mainly used for the preservation and refrigeration/freezing of perishable goods such as food and medicine. It is characterized by its large space and adjustable temperature (refrigeration or freezing). It often uses polyurethane (PU) foam panels for insulation and achieves temperature control through refrigeration units. It is widely used in restaurants, supermarkets, laboratories, and logistics warehouses.
Key Features:
Large Capacity: Large volume, capable of storing a large number of items.
Flexible Temperature Control: Can be set to refrigeration (above 0℃) or freezing (below -18℃) temperatures to meet different needs.
High Insulation: Typically uses low thermal conductivity, high-strength insulation panels.
Customization: Panel color, size, and configuration can be customized to requirements.
Wide Applications: Used in the food (fresh and frozen) industry, pharmaceuticals, chemicals, and other sectors.
Common Types and Refrigeration Methods
Refrigerated Storage: Temperature ranges from 0℃ to 7℃, used for short-term preservation.
Frozen Storage/Low-Temperature Storage: Temperature typically ranges from -18℃ to -30℃, used for long-term freezing and storage.
Refrigeration Methods: These include direct cooling and air cooling (air circulation). Air cooling provides fast and uniform temperature control but can easily dry out food. Direct cooling offers better preservation but has relatively uneven temperature control.
Main Application Scenarios
Commercial: Kitchens and warehouses in supermarkets, hotels, restaurants, and food processing plants.
Logistics: Sorting and transshipment in cold chain logistics.
Research/Medical: Refrigeration of samples or pharmaceuticals in laboratories and hospitals.
Components
Insulated Storage Body: Assembled from foam panels.
Refrigeration Unit: Compressor, condenser, evaporator, etc.
Control System: Temperature controller, display, etc.
Doors and Lighting: Doors with sealing strips, internal lighting.
In summary, walk-in cold storage is a large, flexible cold storage solution that provides convenience for various items requiring low-temperature storage through its customizable low-temperature environment.
