Differences Between Cold Room and Cool Room

In the realm of climate-controlled spaces, the terms “cold rooms” and “cool rooms” are often used interchangeably, but they have distinct differences that are paramount to understand. These rooms are specifically designed for maintaining particular temperature ranges and serve various purposes across industries, from food storage to pharmaceutical applications. This blog post helps you to clarify the features and uses of cold rooms versus cool rooms, allowing you to understand their unique characteristics and applications in a variety of fields.

What are the Cool Rooms?

Cool rooms, also known as walk-in chillers, are large spaces that maintain temperatures between 0°C and +10°C. They are used for storing items that need easy access and are not for long-term storage, such as fresh food like meat and hot pot ingredients.

These rooms have rubber-sealed glass doors and offer plenty of storage, which helps keep food fresh and reduces spoilage. For instance, supermarkets use cool rooms to store fresh produce and other perishable items, making restocking easier. They can also have features like door alarms and warning lights to limit how long the door stays open, helping to lower electricity bills.

What are the Cold Rooms?

A cold room acts like a refrigerator, creating a controlled environment that is different from the outside weather. It includes chillers (0°C to +10°C) and freezers (-18°C to -40°C), along with humidity control. The main goal is to keep stored items fresh by maintaining steady temperature and humidity. Cold rooms can be customised in size and cooling power to meet different needs, making them useful in various industries. The types of items stored and their temperature needs vary depending on their purpose.

Key Differences Between the Cold & Cool Rooms

Cold rooms and cool rooms play a crucial role in preserving the freshness of food and other perishable products. Yet, many individuals frequently confuse these two terms. Comprehending the distinguishing points between them is essential for making the right choices according to your needs. Below, we discuss the key differences between cool rooms and cold rooms:

Temperature Range

Cold Room

A cold room should be much colder than a cool room. Usually, cold rooms maintain temperatures ranging from -18°C to -25°C (-0.4°F to -13°F). These frigid temperatures are ideal for keeping frozen goods such as meat, seafood, ice cream, and other frozen items.

Cool Room

A cool room has a temperature of 2°C to 8°C (35.6°F to 46.4°F). This range is ideal for storing fresh fruits, vegetables, some medicines, and dairy products.

Purpose of Storage

Cold Room

Cold rooms store frozen foods for a long time. They are often used in industries that handle large amounts of frozen goods, like food processing and distribution centres.

Cool Room

Cool rooms are perfect for storing perishable items that require to be kept cooled but not frozen for a short to medium time. Restaurants, hotels, supermarkets, and hospitals often use them for daily storage requirements.

Construction & Insulation

Cold Room

Cold rooms are built with strong insulation that keeps them very cold for freezing. Good insulation materials reduce heat transfer, which helps save energy.

Cool Room

Cool rooms have insulation that efficiently manages moderate temperatures. They are designed to keep heat out of the storage area, but their insulation is not as strong as that of cold rooms.

Energy Consumption

Cold Room

Cold rooms typically use more energy than cool rooms because the ultra-low temperatures require the cooling systems to operate more intensively to maintain a consistent freeze.

Cool Room

Cool rooms are more energy efficient because they operate at higher temperatures, which means cooling systems don’t have to work as hard to keep things cool.

Applications

Cold Room

Cold rooms are widely utilised in several industries, including:

• Frozen foods storage and delivery
• Ice cream manufacturing and storage
• Pharmaceutical companies (for temperature-sensitive medicines)

Cool Room

Cool rooms are used in many places, such as:

• Restaurants and hotels
• Supermarkets and grocery stores
• Flower shops
• Medical facilities for storing vaccines and medicines

Humidity Control

Cold Room

Cold rooms have humidity control systems for preventing freezer burn and keeping frozen products fresh for longer.

Cool Room

Cool rooms feature humidity control systems that keep perishables fresh and maintain their quality.

Here’s a table outlining the key differences between cold and cool rooms, including temperature ranges, uses, and storage needs:

Conclusion

Understanding the distinction between cold rooms and cool rooms is essential for different applications, from food storage to industrial procedures. Cold rooms are maintained at lower temperatures for long-term preservation, while cool rooms serve to keep products at moderate temperatures for shorter durations. The knowledge of these differences enables individuals and businesses to make better decisions based on their storage needs, ensuring the longevity and maintaining fresh quality of their items.
