Cold Room VS Cool Room,which is better?

Cold room and Cool room rooms are two common types of facilities used in the commercial and industrial sectors to store and preserve food and other temperature-sensitive items.Cold rooms and Cool rooms are two types of facilities widely used in the commercial and industrial sectors for storing and preserving food and other temperature-sensitive items. They each have a range of advantages and disadvantages and are suitable for different application areas.


Here are some of the material differences between them:


Insulation material:


Cold Room: Because cold room needs to maintain extremely low temperatures, its insulation materials are often denser and more efficient. Common insulating materials include polyurethane foam, polystyrene foam (EPS), polyurethane sandwich panels, etc., to ensure minimal heat transfer.

Cool Room: Temperature-controlled rooms do not usually require such strong insulation, so lighter insulation materials such as polystyrene foam board (EPS) or polyethylene foam board can be used. These materials can provide enough insulation to keep the temperature in the room within the desired range.


Wall and roof materials:


Cold Room: The walls and roof of a cold room are usually constructed of stainless steel, aluminum, or other low-temperature resistant materials to prevent cold air leakage and frost formation.

More common building materials such as steel, fiberglass or concrete can be used for the walls and roofs of temperature-controlled rooms, as they don't require such strict low temperature requirements.


Floor material:


Cold Room floors usually need to use special floor materials that are resistant to freezing, such as concrete floors, to prevent freezing and water accumulation in the cold room.

Cool Room: The floor material of the temperature controlled room can be regular concrete floor or other appropriate material to meet the hygiene and temperature requirements.


Advantages of cold room:


Extremely low temperature range: Cold room is able to maintain extremely low temperatures, usually between -20°C (-4°F) and -40°C (-40°F), or even lower. This makes it ideal for frozen foods and items that require extremely low temperatures.


Long-term room capacity: Due to its low temperature environment, cold room is able to extend the shelf life of food and items and reduce the risk of spoilage and microbial growth, so it is suitable for long-term room.


Suitable for industrial and commercial use: Cold room is commonly used in industrial and commercial environments, such as food processing plants, frozen food distribution centers, pharmaceutical manufacturing plants and chemical plants. They can handle large-scale room needs.


Precise temperature control: Cold stores are often equipped with advanced temperature control systems that ensure a constant low temperature, thereby maintaining the quality of stored items.

Disadvantages of cold room:


High energy consumption: Cold room usually has a high energy consumption due to the need to maintain extremely low temperatures, which leads to high operating costs.


Not suitable for retail: Due to its low temperature, cold room is not suitable for retail or display goods, so it is not suitable for use in retail environments such as supermarkets.


Advantages of cool room:


Moderate temperature range: The temperature range of the cold room is usually between 0°C (32°F) and 5°C (41°F), suitable for many foods and goods, such as fresh vegetables, fruits, dairy products and beer.


Suitable for retail: Cold rooms are suitable for retail and display goods, so they are commonly found in commercial places such as supermarkets, restaurants, bars and cold drink shops.


Relatively low energy consumption: Due to the low temperature range, cold rooms usually have relatively low energy consumption, which reduces operating costs.


Suitable for short-term room: The cold room is suitable for goods that require short-term room, such as fresh ingredients and drinks.


Disadvantages of cool room:


Temperature limitation: Due to the narrow temperature range, the cold room is not suitable for the long-term room of frozen foods or items requiring lower temperatures.


Not suitable for extreme environments: The cold room cannot maintain extreme low temperatures, so it is not suitable for some special needs environments.


The difference:


Temperature range: The most significant difference is the temperature range. The cold room room maintains an extremely low temperature, while the cold room room maintains a relatively low temperature.


Applications: Cold room is mainly used in industrial and commercial environments, while cold room is suitable for retail and commercial places where goods are displayed.


Insulation requirements: Due to the need to maintain different temperature ranges, cold room has higher insulation requirements and usually has a thicker insulation layer.


Refrigeration systems: Cold stores often require more powerful chillers to maintain the extremely low temperatures required.


Switching frequency: Due to different application requirements, the frequency of use of cold rooms and cold room doors is also different.


The choice between a cold room and a cool room depends on factors like the type of products you need to store, the required room temperature, the duration of room, and energy efficiency considerations.


Here's a comparison chart highlighting the key differences between a Cold Room and a Cool Room:


Cold Room

Cool Room

Temperature Range

Maintains temperatures below freezing (typically -18°C or lower).

Maintains temperatures above freezing but cooler than room temperature.


Long-term room of frozen or deep-frozen products (e.g., meat, seafood).

Short-term room of perishable goods (e.g., fruits, vegetables).

Refrigeration System

Requires powerful refrigeration systems for very low temperatures.

Less intensive refrigeration systems for moderately cool temperatures.

Energy Consumption

Typically consumes more energy due to lower temperatures.

Generally consumes less energy due to higher temperatures.

Moisture and Humidity Control

Often includes humidity control to prevent freezer burn.

May have humidity control but less critical than in cold rooms.

Shelf Life Extension

Extends the shelf life of products significantly.

Extends the shelf life but not as much as in cold rooms.


Ideal for businesses with long-term frozen room needs.

Suitable for businesses that require temporary cooling.


Used for storing frozen goods, ice cream, and similar products.

Used for storing fresh produce, dairy, and beverages.

Environmental Impact

May have higher energy consumption and environmental impact.

Generally more energy-efficient and eco-friendly.


Higher operating costs due to lower temperatures.

Lower operating costs due to higher temperatures.

Fire Safety

No specific impact on fire safety.

No specific impact on fire safety.


In summary, neither is inherently better than the other; it's about selecting the one that aligns with your specific room needs and operational requirements. A cold room is better for deep freezing, while a cool room is suitable for maintaining cooler but non-freezing temperatures.
