Cold storage refrigeration is essential for businesses dealing with food, dairy, medicines, vegetables, frozen products and other temperature-sensitive products. A good cold storage refrigeration system helps maintain the right temperature, protect product quality, reduce spoilage and support smooth day-to-day operations. Choosing the right system is important because every facility has different product, space and temperature requirements.

Aman Refrigeration provides industrial refrigeration solutions for food processing, cold storage, dairy, pharmaceuticals, agriculture, hospitality, and other industries. Its range includes ammonia refrigeration units, Freon air- and water-cooled refrigeration units, evaporative condensers, cooling towers, heat exchangers, pressure vessels, pump recirculation systems, air cooling units, and automation and control panels.

What is refrigeration in cold storage?

Cold storage refrigeration is a cooling system to keep the temperature inside a storage space insulated at a controlled level. The system removes heat from the room and rejects it out of doors. Keeps stored goods at their required temperature range.

Each product has its own set of conditions. Some products like fresh fruits, vegetables, dairy products and beverages may require cold storage while others like meat, seafood, ice cream and frozen foods require much colder temperatures.
The system should therefore be selected depending on the product, size of the room, the insulation, the ability to store, the door openings, the loading of product and temperature required.

How it Works

The basic refrigeration cycle has 4 major steps. These are  Condensation, Compression, Expansion & Evaporation

• Compression: The compressor takes low-pressure refrigerant vapor and compresses it into a high-pressure, high-temperature gas. This creates the pressure needed to move refrigerant through the system.
• Condensation: The hot refrigerant enters the condenser. Heat is released to the surrounding environment, and the refrigerant changes into a high-pressure liquid.
• Expansion: The liquid passes through an expansion device. Its pressure and temperature drop before it enters the evaporator.
• Evaporation: The refrigerant absorbs heat from inside the storage room through the evaporator. Fans circulate cooled air around the room so the required temperature can be maintained.

  
  
  

Main Features

Cold storage refrigeration systems consist of interrelated components. The compressor pumps the refrigerant around and the condenser takes the heat away and the evaporator takes the heat away from the storage room. An expansion device controls the flow of refrigerant.

It reduces the pressure. Temperature sensors and controllers maintain the desired conditions. And insulating panels help reduce heat transfer. Doors that seal tightly help keep warm air in.

Types of Cold Storage System

• Chilled Storage: For products requiring controlled temperatures above freezing, e.g. fruit, vegetables, dairy products, drinks, flowers and fresh foods.
• Frozen Storage: Storage of frozen foods, meat, seafood, ice cream and frozen vegetables at a lower temperature.
• Walk-in Cold Rooms Easy to access refrigerated space for restaurants, hotels, supermarkets, commercial kitchens, food processors and other businesses.
• Industrial Cold Storage: Suitable for large warehouses, food processing plants, distribution centres and agricultural operations. Such facilities frequently require large capacity systems designed for regular or continuous operation

Aman Refrigeration also provides tailor made cold room solutions depending on product type, storage volume and available space such as modular cold rooms and walk in freezer applications.

Benefits of Good Cooling

A well designed cold storage refrigeration system can help protect product quality, reduce spoilage, improve energy efficiency, support better inventory planning and minimise unexpected downtime. It also helps to maintain quality from production line to retail store.

Good refrigeration can be especially useful for businesses that deal with products that have a short shelf life. With the temperature constant you will have less product loss and more control of storage conditions.

Why do they use ammonia as a refrigerant?

Ammonia refrigeration is widely used in large industrial applications . It has good heat transfer properties and is well suited for large scale cooling. Aman Refrigeration offers ammonia refrigeration systems for cold storage and food processing applications.

Planning big facilities is a delicate business. Considerations include cooling capacity, operating temperature, safety, equipment layout and expected operating condition. Other equipment can include evaporative condensers, pump recirculation systems and control panels, pressure vessels.
