Fixed Cold Storage

Introduction to Fixed Cold Storages

Fixed cold storage is a type of cold storage unit commonly used in restaurants, hotels, retail stores, public cold storage facilities, and various other applications.

Fixed cold storage involves insulating a small room inside a building and installing refrigeration equipment within it. Above-zero cold rooms are used for dairy products, fruits, and vegetables, while below-zero cold rooms are used for storing meat and protein products.

Advantages and Disadvantages of Fixed Cold Storages

Fixed cold storage is among the most widely used cold storage units in the industry and market, offering several advantages and disadvantages.

Advantages:

• High strength and durability of the cold room body
• Ability to be constructed for large capacities
• Shelving for easier storage and retrieval of products

Disadvantages:

• Immobility in case of problems or relocation
• High construction costs

Components of Fixed Cold Storages

1. Compressor: The compressor’s function is to compress the gas and create the highest gas pressure in the cold room, initiating the refrigeration cycle.
2. Condenser: Cools the high-pressure gas compressed by the compressor.
3. Evaporator: Evaporators act as coolers inside the cold room chamber, removing heat from the cold room interior using an expansion valve and fans.

Conclusion

In summary, fixed cold storage (below-zero and above-zero) is a stationary chamber that serves as a large refrigerator for storing food, fruits, medicines, dairy products, and protein materials.

Fixed cold storages are commonly used in large restaurants, hotels, butcher shops, hypermarkets, pharmacies, and laboratories and are highly versatile. They are economically viable for storing products in large quantities.
