Walk-in cold storage is a large, accessible refrigerated or frozen storage facility widely used in the food, 

pharmaceutical, and chemical industries for bulk storage of items requiring low-temperature preservation.

Key Features:

Large Capacity: Suitable for bulk storage; internal design includes shelving and automated tracks for easy stacking management.

Wide Temperature Range: 

Supports different temperature zones including 0~15℃ (fruit and vegetable preservation), 

-18℃ (meat freezing), and -60℃ (ultra-low temperature).

Structure Type: 

Mostly prefabricated cold storage units; some utilize mobile designs or on-site installation of a hexahedral structure.

Equipment Components:

Refrigeration System: Includes a compressor, condenser, expansion valve, and evaporator, achieving cooling through a vapor 

compression refrigeration cycle.

Insulation Materials: 

Commonly uses polyurethane color steel plates, extruded polystyrene boards, or embossed aluminum plates, 

providing both thermal insulation and flame retardant properties.

Application Scenarios:

Food Cold Chain: Storing frozen foods and fresh produce, reducing door opening time to lower energy consumption. 

Pharmaceutical industry: Meets the dual-temperature zone or ultra-low temperature storage requirements for pharmaceuticals and vaccines. 

Industrial warehousing: Suitable for efficient storage of large quantities of raw materials or finished products.
