Cold Room Manufacturer

Cold room is a kind of refrigeration equipment, refers to use artificial ways creating an environment different from the outdoor temperature or humidity. It’s also a constant temperature and humidity storage device for food, liquid, chemical, pharmaceutical, vaccine, scientific experiments,etc.

“Speedway” cold room adopts a variety of high-quality materials (stainless steel, color steel plate, aluminum plate, 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.

Cold Room Calculation

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.

Cold room structure

Cooling Capacity Calculation

#1. Medium & high 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

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.

Cold Room Classification

By Temperature

#1. High Temp

Temp > 0°C.

Store fruits and vegetables, eggs, medicinal materials, wood (preservation),etc.

#2.Medium & low Temp

-18°C<Temp <°C.

Store meat, seafood and commodities suitable for this temperature.

Mobile cold room

#3. Low Temp

Temp is -20°C~-30°C.

Freezing food through air cooler or special freezing equipment.

#4. Ultra Low Temp

Temp <-30°C.

Quick-frozen food and industrial experiments, medical treatment, cold chain transportation.

By Scale

#1. Large

Volume> 20,000m3

#2.Medium

5,000m3<Volume<20,000m3

#3. Small

Volume<5,000m3

By Refrigerant

#1. Ammonia

Cold room use ammonia as refrigerant.

#2.Freon

Cold room use freon as refrigerant.

By Grade and Material

#1. High-Level

Use high-quality polyurethane (anti-flaming, grade A) insulation panel or high-quality stainless steel (frosted or polished material, grade A) to build, with relatively high price.

#2.Medium-Level

Use ordinary polyurethane (non-flaming) insulation panel or normal stainless steel (no frosted no polished material) to bulid, with cheaper price.

#3. Fiber Reinforced Plastics

Also called FRP, means cold room body use FRP to build.

#4.Color Steel

Cold room body use color steel to build.

Considerations for Qualified Cold Room

#1. Panel

Made of PU (Polyurethane) or PIR (Polyisocyanurate Foam), two sides use steel plate or stainless steel 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.

Must double check you need 50Hz or 60Hz?

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

#3. 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.

#4. 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).

#5.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  d rainage floor drains to facilitate sewage discharge when cleaning the cold room.

#6. 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.
