Cold room, also called cold storage, refrigeration room, walk in cooler or walk in freezer (depend on room temp), is a kind of refrigeration equipment refers to use artificial ways creating an environment different from the outdoor temperature and humidity. Due to its constant temperature and humidity, cold room always used to store foods, industrial raw materials, biological products and medicines which have special requirements on temperature and humidity.
“Speedway” cold room adopts a variety of high-quality materials (stainless steel, color steel, aluminum, etc), which are suitable for the needs of different ambient temperatures in different countries around the world.
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 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
Etc.
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.

#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).
#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 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.
