Know how to calculate cold storage capacity will help businesses determine the appropriate design space for the quantity and type of products that need to be preserved. At the same time, when you know the capacity of the cold storage, you can also estimate the amount of electricity consumed and the amount to be paid monthly. If you do not know how to calculate the cooling capacity for the cold storage, follow Tan Long in the article below!
What is the capacity of the cold storage?
Cold storage capacity is always a crucial and top priority factor in the design and installation process. Cold storage capacity reflects the cooling capability of the warehouse; the larger the capacity, the higher the cooling capacity, and vice versa. The method for calculating cold storage capacity varies depending on the area and volume of goods to be stored.
Cold storage are most widely used in the food preservation industry. In addition, they are also used to preserve pharmaceuticals and other supplies. Each type of goods has its own packaging requirements and storage environment, so cold storage are often divided into different groups.
For example, freezer warehouses are used for preserving food, freezer warehouses for preserving seafood, cold storage warehouses for preserving fruits and agricultural products, and cold storage warehouses for preserving pharmaceuticals. Vaccine, cold storage for beer and fermented products,...
Why do you need to know how to calculate the cooling capacity for cold storage?
Cold storage capacity directly affects the ability to preserve goods. Furthermore, knowing how to calculate cold storage capacity will help businesses estimate investment costs and monthly electricity consumption, thereby optimizing monthly operating costs.
- If the cold storage area is too large compared to its capacity, the refrigeration system will encounter many problems due to insufficient cooling capacity, thereby directly affecting the quality of goods and causing significant losses for the business.
- Conversely, if the cold storage capacity is too large compared to the available space while the amount of goods to be stored is not significant, the business will incur high investment and operating costs.
The most accurate way to calculate cold storage capacity today
To use cold storage efficiently and save energy, you need to know how to calculate its cooling capacity. The formula for calculating cold storage capacity is as follows:
Capacity = Number of HP x 0.746kW x Number of running hours
For example: For a cold storage facility with a temperature range of 0°C to 10°C, using a Copeland compressor with a power of 3.5 HP and a running time of 1.5 hours, the cold storage capacity will be: 3.5 HP x 0.746kW x 1.5 = 3.9165kW/h.
Once the amount of electricity consumed is known, the monthly cost will be calculated according to the formula: Cost (VND) = kW/h x Number of days.
Note: The two main factors determining the cooling capacity of a cold storage facility are its volume and internal temperature. Cooling capacity will vary depending on the set temperature. The compressor's operating time per hour will also differ depending on the type of compressor. So now you know how to calculate cold storage capacity!
How to calculate cold storage capacity
Job cold storage capacity calculation It is essential to ensure that the design space is suitable for each type and quantity of products required. This directly affects the usable space as well as the cost of related equipment, machinery and materials. Therefore, the calculation of capacity needs to be done carefully and accurately.
Step 1: Determine the volume of cold storage
Cold storage volume is calculated by the formula: V = E/gv (m3). In there:
- V: Cold storage volume (m³).
- E: Expected cold storage capacity (tons).
- teacher: Cold storage load rating (ton/m³).
However, the norm cold storage load There will be differences in each type of product. For example: Frozen beef 1/2 head (0.30 tons/m3), frozen pork (0.45 tons/m3), frozen poultry (0.38 tons/m3), frozen fish (0.45 tons/m3), tomatoes in trays (0.44 tons/m3), ...
Step 2: Calculate the loading area
Cold storage loading area is calculated by the formula: F= V/h (m2). In there:
- F: Loading area (m2).
- V: Cold storage volume (m3).
- h: Loading height in cold storage (m).
Loading height (h) is calculated by the formula: h = h1 – clearance. In there:
- h1 is determined by subtracting twice the insulation thickness δ from the overall height H of the cold storage, using the following formula: h1 = H – 2δ. The overall height H of cold storage is typically designed according to standard dimensions such as 3,000mm, 3,600mm, 4,800mm, or 6,000mm, but can be adjusted to meet specific requirements. The insulation thickness δ of the cold storage ranges from 50 to 200mm, depending on the storage temperature and the characteristics of the cold storage panel.
- This clearance depends on the length of the warehouse and is necessary to ensure air flow. Minimum clearance is usually 500 – 800mm.
Step 3: Calculate cold storage area
Reality, cold storage construction area not only enough to hold the goods but also must include the necessary spaces for air circulation, installation condenser and for user movement. Therefore, the construction space area will be larger than the area just for storage.
Cold storage area is calculated by the formula: FXD= F/βT (m2). In there:
- FXD: Area to be built (m2)
- F: Loading area (m2)
- βT: This coefficient is applied to calculate the walking space area, the distance between products and the area required for installing the air conditioner, etc.
Determine the Utilization Factor area βT as follows:
| Cold room area (m2) | βT coefficient |
| Under 20 | 0.50 – 0.60 |
| From 20 – 100 | 0.70 – 0.75 |
| From 100 – 400 | 0.75 – 0.80 |
| Over 400 | 0.80 – 0.85 |
Once the actual area for the warehouse has been determined, the designer will use the available space limitations to determine the width and length of the warehouse. Below is a reference table for determining warehouse size based on capacity:
- 25 tons: 5400 x 5400 x 3000 mm.
- 50 tons: 10800 x 5400 x 3000 mm.
- 100 tons: 10800 x 10800 x 3000 mm.
- 150 tons: 16200 x 10800 x 3000 mm.
- 200 tons: 21600 x 10800 x 3000 mm.
Choose a compressor to help the cold storage operate effectively
The compressor's function is to draw refrigerant from the evaporator and compress it to create high pressure, then push it into the condenser.
Choosing the right compressor ensures high condensing pressure, corresponding to natural environmental conditions for cooling. This leads to more efficient cooling and cost savings through the most effective use of electricity. Selecting the appropriate compressor also ensures the cold storage facility operates efficiently, guaranteeing optimal preservation of goods and products.
