Heat exchangers come in various types, such as air-cooled, shell and tube for water-cooled systems, and plate types.

Cold Room Insulation:

Insulation stands as a pivotal factor influencing cold room quality and energy consumption. Different insulation types include:

– Polyurethane Sandwich Panels: Featuring double-sided colored sheets with a density of 40 kilograms per cubic meter and thicknesses from 5 to 15 centimeters. These panels offer superior insulation, lower heat transfer coefficients, and ease of mobility.

– Insulation Sheets (EPS/XPS): Available with densities ranging from 20 to 40 kilograms per cubic meter and varying thicknesses.

– Doors: Crafted from injected polyurethane, these come in sliding and hinged types with customizable frames and fittings.

Choosing insulation involves considering the heat transfer coefficient; superior insulation translates to reduced equipment wear and lower electricity consumption, allowing for smaller cold room units.

Other Cold Room Equipment and Components

Beyond the mentioned components, a cold room incorporates various essential parts. Valves, refrigeration cycle controllers, and the electrical panel significantly contribute to efficiency and precise parameter control. Atlas Refrigeration Co. utilizes products from reputable brands like Danfoss, Castel, Parker, Hansen, Schneider, and Siemens. Contact us for equipment prices.

Categorizing Cold Rooms by Temperature Range

Below-Freezing Cold Room:

Primarily utilized for items like ice cream, butter, various meats, and frozen products, a below-freezing cold room maintains temperatures between -5 to -30 degrees Celsius. Adequate insulation, often 15 centimeters thick in polyurethane sandwich panels, is standard for this type of cold room.

Above-Freezing Cold Room:

Tailored for fruits, vegetables, medicines, cakes, and pastries, an above-freezing cold room adjusts its temperature based on stored products. For instance, medicines typically require temperatures within +4 to +8 degrees Celsius, while fresh apples thrive between -1 to +3 degrees Celsius. Insulation recommendations for above-freezing cold rooms lean towards a 10-centimeter thickness in polyurethane sandwich panels. Contact us for detailed information and prices regarding above-freezing cold room solutions.

Types of Cold Rooms by Function

Industrial Cold Room:

Designed for capacities exceeding 1,500 tons, an industrial cold room often partitions its total capacity into multiple chambers. This division offers several advantages, allowing for separate storage of diverse products within individual chambers. Additionally, during periods of lower

cold room utilization, smaller chambers can be activated, bypassing the need to control the temperature of larger tonnage areas. Industrial cold rooms typically employ ammonia-based refrigeration systems for optimal functionality. Explore industrial cold room prices for detailed insights.

Containerized Cold Room:

Characterized by mobility, containerized cold rooms suit individuals requiring a cold room in rented spaces or for temporary workshops outside urban areas. Constructed with iron structures and corner fittings, these rooms boast easy transportation facilitated by attached hooks.

However, adherence to specific dimensions is crucial during transportation to avoid categorization as traffic loads, which could pose challenges for cold room owners. The allowable dimensions are as follows:

– Maximum Length: 12 meters

– Maximum Width: 2.5 meters

– Maximum Height: 3 meters

Types of Cold Rooms Based on Refrigerant

Freon Cold Room:

Freon cold rooms utilize refrigerants from the freon family in their refrigeration cycles. Freons, divided into old (environmentally harmful) types like R-22 and R-11, and new (environmentally friendly) ones like R-134A and R-404A, offer versatility across compression cycles employing hermetic, semi-hermetic, and open compressor types. The non-reactivity of freons with copper, used in motor windings of hermetic and semi-hermetic compressors, makes them a viable choice. These colorless, odorless gases pose minimal toxicity and flammability risks. Suited for small and medium cold rooms, freon isn’t recommended for industrial setups. Freon cold rooms typically exhibit a Coefficient of Performance (COP) averaging between 6 to 7, contingent on the freon type utilized. Discover more about freon cold room pricing for detailed information.

Ammonia Cold Room:

Employing ammonia gas as a refrigerant, ammonia cold rooms champion an environmentally friendly approach. Industrial systems using ammonia necessitate central motor room type setups compatible with non-colored metals (excluding copper and brass) in contact with ammonia. Notably, fewer compressors suffice for larger capacities;

for instance, a 5,000-ton cold room might require two screw compressors with one serving as a backup. With a Coefficient of Performance (COP) averaging around 8, ammonia cold rooms boast reduced energy consumption compared to their freon counterparts. Delve deeper into ammonia cold room prices for comprehensive insights.

Categorization of Cold Rooms by Volume

Understanding the varied sizes of cold rooms aids in their classification:

– Small Cold Room: Less than 50 cubic meters

– Commercial Cold Room: Ranges between 50 and 500 cubic meters

– Medium or Semi-Industrial Cold Room: Varying from 500 to 5,000 cubic meters

– Large or Industrial Cold Room: Exceeds 5,000 cubic meters

Calculating a cold room’s volume involves multiplying its length, width, and height. For instance, a cold room measuring 10 meters in length, 6 meters in width, and 4 meters in height totals a volume of 240 cubic meters, categorizing it as a commercial cold room within the specified range.

Calculating Cold Room Dimensions Based on Loading Capacity

Determining the required space for product storage involves careful consideration of product arrangement to facilitate easy access for equipment and ensure adequate cold air circulation.

Method 1: To accurately estimate dimensions, it’s recommended to gather information on packaging methods and product density before constructing the cold room.

Method 2: Approximate dimensions can be derived based on estimated product weight:

– For products stored below zero degrees (e.g., meat, poultry, fish), allocate 3 to 3.5 cubic meters per ton (1000 kilograms) of product.

– For products stored above zero degrees (e.g., fruits, vegetables), allocate 4 to 4.5 cubic meters per ton (1000 kilograms) of product.

Considerations for accessibility and air circulation space are integral aspects in this estimation method, ensuring optimal functionality within the cold room.
