Cold room structure

Cooling Capacity Calculation

#1. High & medium temperature cold room

Cold room volume (m3)×90×1.16+ deviation. The deviation range is 100~400W.

For example: a cold room volume is 90m3, so should choose cooling capacity: 90x90x1.16+≈200W =9,596W

Others the same.

#2. Low temperature cold room

Cold room volume x 110 x 1.2 + deviation. The deviation range is 300~800W.

Storage Capacity Calculation

Cold room storage capacity =

Internal volume × volume utilization coefficient (volume coefficient * temperature coefficient) × food weight per CBM

(CBM means “cubic meter”, also called “m3”)

#Volume Coefficient:

Cold room volume   Coefficient

500~1000 m3               0.5
1001~2000 m3             0.55
2001~10000 m3           0.6
10001~15000 m3         0.7

#Temperature Coefficient:

High temperature ( >0°C ): 1.2
Medium and low temperature ( -18~0°C ): 1
Ultra-low temperature ( <-30°C ): 0.85

#Food Weight per CBM:

Frozen meat and fish: 0.40~0.47 ton

Fresh fruit and vegetable: 0.25~0.35 ton

Ice cubes: 0.7~0.85 ton

Boxed frozen poultry: 0.55~0.65 ton


Question: 1000m3 low temp cold room can max store how many tons fresh fruit?

Answer: 1000 x (0.5 x 1) x 0.35 =175 ton.

Considerations for Qualified Cold Room

#1. Panel

Made of PU (Polyurethane) or PIR (Polyisocyanurate Foam), two sides use steel plate, stainless steel plate or aluminum plate which must be anti-flaming. The coating on both sides must be non-toxic, odor-free, corrosion-resistant, and meet international food standards.

Due to different cold room temperature should select panel with different thickness.

Panel thickness:

Medium & high temperature :100mm

Low temperature:150mm

Ultra low temperature : 180mm or more

#2.Refrigeration System

Cooling capacity of the refrigeration equipment needs to match the volume and temperature of the cold room. Wrong configuration can increase your costs, or reduce the cooling effect.

Top brand compressor: Danfoss/Copeland/Tecumseh, but the price is high; Normal brand compressor: Panasonic/Sanyo/Highly
price is cheaper, but the cooling effect is not bad.

1) .Must double check you need 50Hz or 60Hz?

2).You want non-inverter or inverter ( can save approx. 40% energy power) ?

For specific needs, please Contact Our Salesman, they will give you suitable solutions.

#3.Size and Capacity

Ensure cold room is of the appropriate size and has sufficient capacity to meet your storage needs.

The size and capacity of a cold room are important considerations when choosing the right cold room for your needs. The size of the cold room will depend on the volume of items that need to be stored and the available space in your facility.

Too small cold room may not be able to accommodate all your storage needs, while too large can be wasteful and inefficient. 

#4. Door

Its thickness, surface and thermal insulation performance should be same as the Cold Room Panel, and must be no gaps between the door and door frame. The door should have lock, which needs a safe release function.

All doors must be flexible and lightly open or close. The contact surface between door frame and the door itself must be smooth and flat, to ensure the sealing strip can be sealed well.

#5.Safety Features

The cold room should have safety features such as emergency alarms and backup power systems to prevent loss of stored items in case of power outages or equipment failure.

#6. Location

Cold room shouldn’t be built in the open air. At least the top should have a shelter, the ground should be flat, and the power supply must have two options: 220V and 380V.

Outside the cold room must be a space for placing the Condensing Unit, whose installation should consider ventilation.

When the distance between the power supply and the condensing unit >100m, you need to consider the cooling loss during operation and choose the condensing unit with a larger cooling capacity.

If the cold room isn’t built on the 1st floor, you must notice how all the equipment enters the installation floor? And pay attention to the ground waterproofing (to prevent water from penetrating downstairs) and anti-freeze (to prevent the floor from freezing).


The lighting (moisture-proof and explosion-proof) installed in the cold room needs to be able to work normally at -30°C. The lampshade must be moisture-proof, anti-corrosion, acid-proof, and alkali-proof, and the ground brightness should be >200lux.

All devices in the cold room should be anti-corrosion and anti-rust treatment, but must ensure the coating is non-toxic, doesn’t pollute food, and has no peculiar smell.

The temperature indicator should be installed near the cold room door. Must install drainage floor drains to facilitate sewage discharge when cleaning the cold room.

#8. Stored Item

The storage of different goods in separate room can achieve the best effect and profit, meanwhile avoid the mutual influence between goods.

For example: seafood has a fishy smell so can’t be stored with other meats and foods. Pears & apples will release ethylene during storage, so can’t store with other fruits, otherwise who will be ripened by ethylene and shortened the storage period.

If multiple goods must be stored in the same cold room, necessarily ensure room temperatures of these goods are similar and not affect each other. 

You can also add sealed packaging onto the goods to prevent them from affecting each other.

Maintain proper hygiene in a cold room is essential to ensure the safety and quality of the stored products.

1) Cleaning: The cold room should be cleaned regularly to prevent the buildup of dirt, debris, and microorganisms. The cleaning frequency and methods will depend on the type of product being stored and the level of contamination.

2) Sanitization: After cleaning, the cold room should be sanitized to eliminate any remaining bacteria, viruses, or other pathogens. Can use sanitizing agents such as chlorine or hydrogen peroxide to effectively kill microorganisms.

3) Personal hygiene: Anyone who enters the cold room should follow proper hygiene practices, such as washing hands and wearing appropriate clothing and protective gear. Should also trained employees on proper handling and storage procedures to prevent contamination.

#10. Maintenance

Maintaining a cold room is essential to ensure that it functions effectively. Proper maintenance can help to prevent breakdowns, reduce energy consumption, and prolong the lifespan of the equipment.

Here are some important factors to consider for cold room maintenance: regular inspections, cleaning, temperature & humidity monitoring, record keeping, professional technician servicing,etc.
