Cold Room Components and Structure
Cold Room Excellent Cooling
Our cold room features:
Light weight, high strength, high fire-rating, good thermal insulation performance, corrosion resistance, anti-aging, anti-moth, performance at ultra-low temperature is better than others.
Our cold room has slow cooling capacity outflow speed and the holding time is long. Compared with other cold room can save 30-40% energy.
Do you know how to calculate the correct cooling capacity and storage capacity for your cold room?
You must choose equipment with the right cooling capacity, otherwise won’t achieve the best cooling effect.
Meanwhile, the optimal storage weight can ensure your cold room the best profit.
#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.
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 mt (metric ton)
Fresh fruit and vegetable: 0.25~0.35 mt
Ice cubes: 0.7~0.85 mt
Boxed frozen poultry: 0.55~0.65 mt
Etc.
Question: 1000m³ low temp cold room can max store how many mts fresh fruit?
Answer: 1000 x (0.5 x 1) x 0.35 =175 mt.

Assume your local site has about 4–6 “equivalent full‑sun hours” per day.
Formula: PV size (kWp)=Daily kWh required ÷ Sun hours per day
Example: Daily load = 12 kWh, sun hours = 4 hrs, PV size=12÷4=3 kWp
Notice: In cloudy or tropical regions, add 10–20% extra PV capacity as a safety margin.
Battery capacity depends on how many hours you want to keep the cold room running without sun.
Formula: Battery kWh=Daily kWh×Backup days÷Depth of discharge
Example: Daily load = 10 kWh, want 1 day backup, acceptable depth of discharge = 60%:
Notice: For a 48 V system, this would be about 350 Ah (since 17,000 Wh ÷ 48 V ≈ 354 Ah)
No worry, our cooling capacity tonnage calculator will help you !
Press and hold “SET” button for 10 seconds, then release it.
Press and hold “SET” button for 1 seconds, then release it.
Now the “off temp” is showed in there! You can set the “off temp” as your need (“↑” up and”↓” down). Adjust the “off temp” and leave it alone. It will be saved automatically in 10 seconds.
Use the same method of step 3 to set ”on temp”.
“On Temp”–Compressor will start working when cold room reach the on temp.
Then the cold room can work as your “on temp” and “off temp”.
“Off Temp”–Compressor will stop working when cold room reach the off temp.
Notice: “On temp” is 4~5°C higher than “Off temp”.
Then you can set:

#1. Panel
Core is made of PU (Polyurethane) or PIR (Polyisocyanurate Foam), two sides’ surfaces use color steel, stainless steel or aluminum sheet 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 set temperature should select panel with different thickness.
Panel thickness:
Medium & high temperature :100mm
Low temperature:150mm
Ultra low temperature : 180mm or more
Cold Room Panel Structure
#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/Bitzer/Tecumseh, but the price is high; Normal brand compressor: Panasonic/Sanyo/Highly
price is cheaper, but the cooling effect is also good.
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.
Size and capacity of a cold room are very important when choosing the right cold room for your needs. Cold room size 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
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 have 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).
#7.Auxiliary
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.
#9.Hygiene
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 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.
