What is a Cold Room Used for？
The cold room is becoming more and more important for our daily life, for fulfilling people’s demand for fresh food.
Correspondingly, the cold room business has also grown rapidly these years, no matter for building cold rooms or cold room rent business.
What is a cold room used for?
High-temperature cold room(Around 5°C): suitable for the preservation of fruit and vegetables.
Medium-temperature cold room(-10°C~-5°C): suitable for cold storage the frozen food.
Low-temperature cold room(-20°C~-10°C): suitable for freezing aquatic products and poultry food.
Ultra-low temperature(Below -23°C): suitable for quick freezing products.
The cold room is widely used for cold storage of food, such as cold room for fruits and vegetables(cold room for potato, cold room for tomato, cold room for onion, etc), cold room for seafood and meat.
The cold room is also widely used for improving the level of our life, such as a cold room for medicine, a cold room for flowers, and mini cold storage, etc.
Analysis of the Commercial Value of Seven Types of Cold Room
With the development of the world economy, people’s requirements for fresh food and comfortable life are getting higher and higher.
The types of cold rooms are also changing during the development process.
Different types of storage cold rooms, market cold rooms, etc. are blooming everywhere, for all humans.
After more than 20 years of hard work, Miracle has also served dozens of countries and hundreds of different types of cold room projects, all of which have gained a good reputation.
We firmly believe that with the continuous efforts of our Miracle people, we will contribute our wisdom and strength to the development of the world’s cold room and preservation business.
Storage Cold Room
The storage-type cold room is the most constructed cold room in the 1980s and 1990s.
At present, it is the largest type of cold room on the market, mainly used for the storage of frozen products such as aquatic products and meat.
This type of cold room is based on commodity storage functions, with fewer commodity categories, with a storage period of as little as six months and as long as one year.
Therefore, the design of the temperature zone is relatively simple.
The frozen products are mainly stored in piles, and there are certain requirements for the storage capacity.
The requirements for the area and temperature of the shipping area are relatively low. Some cold rooms do not even have a temperature.
Market-based Cold Room
The so-called market-type cold storage is mainly based on the cold storage built in the agricultural wholesale market.
In addition to a certain amount of storage space, this type of cold storage must also be rented out to merchants in the market.
Therefore, more consideration is given to the design of cold storage. Market-type cold storage is currently dominated by multi-story buildings or small-scale cold storage.
The height of each floor of multi-story buildings is about 5 meters, and most of the goods are stored in the form of stacking.
Central and Regional Distribution Cold Room
The cold room of the CDC, RDC and other distribution centers have a large service radius.
When planning the cold room type, the storage function is considered more important than the distribution function.
Due to the distribution function, this type of cold room has certain requirements on the area and temperature of the receiving and shipping areas.
Merchandise storage is mostly in the form of shelves.
The height of the cold room is generally determined by the height of the shelf.
Currently, the height of the shelf is mainly above 4 floors, and some cold room uses the height of 8 floors. In recent years, an automated three-dimensional cold room has been increasingly used in the regional distribution cold room.
City Distribution Cold Room
Priority is given to the location of an urban distribution-type cold room that is closest to the city center or customers and the most convenient location.
Urban distribution-type cold room considers more distribution functions than warehousing functions in the planning of the warehouse area.
The operation process pays more attention to the time and efficiency of commodity circulation, so there are high requirements for channels, storage locations, and purchase and delivery locations.
The urban distribution cold room has certain sorting and tallying functions. The platform area in the warehouse cold room is usually called the tally area here.
The tally area is the most profitable area among all the functional areas of the urban distribution cold room.
The distribution-type cold room has a certain area and temperature requirements for the tally area in the planning, which is one of the important reasons why it is difficult to change the storage-type cold room into an urban distribution business.
Multi-temperature layer layout is the main trend of urban distribution type cold room, and even dry storage areas should be considered.
Central Kitchen Type Cold Room
The large central kitchen operates internally, not only with cold chains but also with hot chains.
Usually integrated design for processing, production, and distribution, with more complex functional partitions.
At present, most central kitchens in the world are self-built and self-operated public central kitchens such as chain supermarkets and airline catering.
The central kitchen has strict requirements for hygiene and has different design conditions for floors, walls, panels, etc.
Some areas, such as clean vegetable processing rooms, have air cleanliness regulations, so different air filtration devices need to be considered in the design to meet the purification requirements.
In addition, since most floors need to be cleaned regularly, the insulation board and floor treatment should not only be sealed but also water-retaining and easy to clean.
Fire protection requirements are also an important part of the design of a central kitchen, such as the setting of fire compartments, passages, and the selection of fire-resistant panels must be considered.
Since the large-scale central kitchen has very scattered functional cold rooms, many temperature zones, and large spans, the refrigeration system should be reasonably distributed and designed. Currently, distributed system designs are often used.
Fruit and Vegetable Production Area Cold Room
The production area cold room is mostly a storage-type cold room.
With the development and application of fresh agricultural products preservation technology, especially vegetables, and fruit agricultural products, more and more attention has been paid to the preservation of freshness after picking.
Therefore, the pre-cooling treatment of vegetables and fruit products after picking is a very important link.
More and more cold rooms built-in production areas in the year are equipped with pre-cooling rooms or pre-cooling equipment.
It provides a more powerful guarantee for the preservation of vegetables and fruits.
The controlled atmosphere cold room in the storage cold room is the most effective way to extend the freshness of fruits and vegetables, but the high construction cost hinders the development of this type of cold room.
With the standardization of the circulation of agricultural products and the extension to the origin, the origin-type cold room has gradually increased the functions of sorting, preliminary processing, packaging, etc.,
With the nature of the transaction market, the smooth tube refrigeration system, fan coil refrigeration system, and mechanical adjustment composite cold storage that matches the integration of electrical control came into being.
This also provides a better solution to the cold chain problem of agricultural products.
E-commerce Distribution Cold Room
Here we refer to the cold room for B2C business as the e-commerce distribution cold room.
This type of cold room is a form of urban distribution cold storage but has its own characteristics in functional planning.
E-commerce home-equipped cold room needs to handle more SKUs(Stock Keeping Unit) and require a large number of cross-docking operations.
In the planning of the storage area, not only need to consider the receiving and shipping area and the tally area, but also the setting of zero-removing, simple processing, and packaging areas.
Due to a large number of partitions, internal trends need to be reasonably arranged.
There are corresponding sanitary requirements for processing and packaging areas in the home-equipped cold room, and clean sheets should be used when choosing insulation materials for a cold room.
In some areas where the flow of fresh agricultural products is low in standardization, automated operations cannot be achieved in the warehouse area, and a large number of manual operations are required, it is also necessary to consider the provision of ventilation devices in crowded areas.
Since most of the cold room of e-commerce home-equipped cold room is operated by cross-docking, the cold room used for storage has a small volume, and the area occupied by personnel is large.
The temperature is controlled between 8-18℃. Miracle water-cooled condensing units can be used in the cooling method.
The unit can save costs and reduce the amount of refrigerant injected, which is more environmentally friendly.
Fan Evaporator in Cold Room VS Aluminum Row Evaporator in Cold Room
The Feature of Evaporator with Fan Motor
1. The structure is compact, and occupy the small space of the cold room, the cold storage space is less affected;
2. High heat exchange efficiency, using fewer materials to reduce costs;
3. The air is forced to circulate by a fan, and the cold room cools faster;
4. Defrosting is convenient and easy to control, can realize automatic control, easy to operate, and easy to manage;
5. Copper tubes with aluminum fins are generally available on the market, withstand higher pressure, have strong corrosion resistance, and are not easy to leak;
6. Due to the forced circulation of the fan, the airflow in the cold room is faster, and unpackaged food is easy to dry;
7. The fan itself consumes power;
8. Universal for high and low-temperature cold room, condensation or frost will not affect the use;
9. Mainly rely on convection heat exchange;
Features of Aluminum Row Evaporator
1. It occupies a large space, which will affect the use area under certain circumstances;
2. Mainly rely on radiation heat exchange, no fan is needed;
3. Cooling is slower than the fan evaporator;
4. The defrost cycle is longer after frosting, generally twice a year;
5. Defrosting can be sweep defrost, electro-defrosted, and hot fluorinated frost, but it cannot be automatically controlled.
The hot fluorinated frost technology is actually used in flooded evaporators (the investment is relatively large, and it cannot be automatically controlled).
Relatively direct expansion is not suitable, and the defrosting water is not easy to handle;
6. Aluminum pipes are generally not seamless pipes. Due to the microscopic thermal expansion and contraction, it is easy to leak after a long time;
7. Its own heat exchange efficiency is low, so the initial investment is relatively large;
8. The cold storage capacity is more advantageous than the fan;
9. It is suitable for sub-zero temperature, otherwise there will be condensation water, which will affect the working environment;
10. No need for fans, energy saving.
Advantages and Disadvantages of Air-cooled/Tube-cooled Cold Room
Air cooling: good cooling effect, fast speed, clean and non-humid storage. once the power is cut off, the cold room’s temperature is easy to lose.
Power consumption, low cost, easy to retrofit, but easy to make the product lose moisture and become dry, which makes the product lose weight and looks not gorgeous.
It is suitable for storing packaged vegetables, fruits, dried goods, storage of medicines, used in restaurants, hotels, etc.
Pipe cold: slow cooling effect, more water in the warehouse, more ice, inconvenient installation, slightly higher cost, power saving.
Once the power is cut off, the temperature can last for some time and protect the products inside of the cold room. It is suitable for storing vegetables and fruits, ice cream cold drinks, fresh meat, etc.
Miracle Cold Room Design Process
After checking what is the cold room and what kind of cold room we have, you must want to ask: how can I get a cold room from Miracle?
Follow me to check the following process and to see how we customized the cold room according to your actual situation and demands:
➯Send cold room inquiry to Miracle
➯Miracle to get to know everything about your project and demands
➯Miracle provides a professional cold room solution
➯Communicate, modify and sign the contract of cold room order
➯Production and delivery of cold room
➯Installation guide for cold room
➯After-sales service.
Let me explain it in detail in the following, or you can contact us directly to get your cold room now.
Miracle Professional Docking
When we receive your inquiry and there will be professional salespeople to contact you for knowing everything about your cold room project.
To better provide a good design for a cold room, you need to provide us with the following information:
The First Step of Cold Room design: selection and preparation of cold room location.
Provide as much info as possible to us and let us know the situation of the place for building the cold room if it is the big cold room you gonna build. For a small cold room, it will have less affection.
The second step of cold room design: determination of cold room warehouse capacity.
Cold room size is an important factor that needs to confirm, but how to calculate the size?
You need to consider the max amount of products that you should store in the cold room throughout the year.
The cold room capacity will be calculated according to the storage products, plus the aisles between rows, the space between the stacks, the space between the ceilings, and the packaging, then decide the cold room’s length and height.
Besides that, you also need to consider the related facilities, for example, the workshops, sorting room, packing room, tool room, and loading docks if you need them when designing the cold room.
The third step of cold room design: Selection of the cold room insulation materials.
When you choose the insulation material for the cold room, you must consider the site conditions, make sure the material has a very good thermal insulation performance and is cost-effective.
Cold room has several types of heat insulation materials to choose from.
One type is that we manufacturer it for fixed length and width, which are widely used by customers.
You can choose the cold room panel according to the specification of the cold room you need.
Generally, a 10cm thickness cold room panel is used for high and medium-temperature cold rooms, low-temperature cold rooms mainly choose a 12cm thickness cold room panel, ultra-low temperature cold rooms need to use a 15cm thickness cold room.
Another type of cold room heat insulation material should be used on concrete buildings or brick buildings, you can spray and foam it on the building with polyurethane, and this material is moisture-proof and heat-insulated after being shaped.
Polyurethane and polyphenylene are the most popular type for this kind of heat insulation material.
Let me introduce the advantage and disadvantages of the two kinds of heat insulation material.
Polyurethane’s cost is a little higher, but it does have better insulation because of not absorbing the water;
Polyphenylene’s cost is lower, but heat insulation is not that good.
Now more and more customers have demands that require the cold room can be installed very fast and convenient, so we normally try to finish the work in the factory,
Such as producing the cold room moisture barrier and heat insulation in advance, then it will save work and time for you.
The fourth step of cold room design: The selection of a cold room cooling system.
When you choose the cold room cooling system, the main parts are the cold room compressor and cold room evaporator.
Normally, small cold rooms will use hermetic compressors.
Because hermetic compressors’ power is not big, and the price is economic, good for the customer to accept, such as Highly compressor, Maneurop compressor, scroll compressor, reciprocating compressor, rotary compressor;
Medium cold rooms and Large cold rooms generally use semi-hermetic compressors, such as Frascold semi-hermetic compressor, Bitzer semi-hermetic compressor, Copeland semi-hermetic compressor;
Of course, you have another choice to use ammonia refrigeration compressors, because the power of ammonia refrigeration compressors is large, and one compressor can be used for multiple purposes.
But the cold room installation and management are more cumbersome for the ammonia compressor units.
When you choose the evaporator, you should know that the air cooler with fan motor blowing will have a fast cooling speed, it is widely used in a high-temperature cold room.
But the disadvantages are easy to make the stored products lose moisture and become too dry.
The medium and low-temperature cold room uses a seamless steel tube evaporator, in which the constant temperature effect is good, and can store the cold in time.
Other factors you need to know for designing the cold room.
If the project is relatively large and you think it’s necessary to let our engineer check the site to design the cold room.
The engineer will go to your proposed cold room construction site to conduct on-site surveys and conduct a comprehensive inspection.
All of this work make sure that the cold room program design can be carried out more scientifically and reasonably.
The measurement content includes:
A. Measure the specific length, width, and height of the foundation (the height is determined according to your requirements), then the engineer will calculate the specific area for each cold room for a different purpose;
B. Meteorological observation, indoor humidity in summer, indoor humidity in winter, average relative temperature of the hottest month and the coldest month, outdoor wind speed in summer, average outdoor wind speed in winter, the annual average temperature at the project site, etc.
Miracle Provide Cold Room Solution, Communicate and Confirm the Order
Further confirming that the use scenarios of the cold room include cold room location, cold room capacity, cold room insulation materials, cold room cooling system, and the number of times of entry and exit per day, and everything we got for your project situation to provide the cold room design.
After you get it, we can talk, modify, and determine the final design.
Of course, we provide the drawings and related budgets at the same time, then sign a cold room contract, after you pay the deposit, we start to produce the cold room.
Package and Shipment
During the production and delivery period, we will always keep you informed, then you can make a good plan for the whole cold room project. We will also handle the clearance and make sure you get the cold room quickly and easily.
Cold Room Installation and Guidance
The construction process of the cold room project includes: construction site cleaning-site marking-refrigeration equipment installation-pipeline air tightness test-electrical system connection-refrigeration unit operation-system debugging
1. Cleaning up the construction site of the cold room.
Clean up debris to ensure that the construction site is clean enough;
2. Cold room on-site marking.
Make accurate and clear signs according to the construction drawings; install the support beams, etc., and the welds shall be treated with moisture and corrosion resistance.
3. Installation of refrigeration equipment in the cold room.
A.Before installation of the refrigeration unit, make sure you level the condensing unit base.
B. Evaporator installation
Check the model, specification, and quantity of the evaporator.
The fan has a uniform surface color, complete structure, no scratches or corrosion, and the copper pipe inlet&outlet should be tightly sealed, and make sure to put the pressure in the refrigeration system of the evaporator.
C. Refrigeration pipeline installation
All pipelines are made of high-quality copper pipes, and Miracle fire-free connection technology is recommended to use for the installation to improve the working efficiency and stability.
Plastic sleeves must be installed and sealed when the pipelines pass through the cold room board. An oil trap must be set at the outlet of the evaporator to facilitate oil return.
4. Cold room pipeline airtightness test.
In the 24h pressure reduction test, the system must be filled with anhydrous nitrogen to maintain pressure, and the compressor itself must not be used for pressure.
5. The refrigeration system blows pollution, evacuates, and refrigerant charge
Blowing: Every copper pipe should be blown before connecting.
Vacuuming: Make sure all the nitrogen has been vent, then use a vacuum pump to vacuum the system. It is strictly forbidden to use the compressor to vacuum.
Refrigerant charging: After the system is vacuumed, the liquid refrigerant should be filled from the receiver to saturation, and then the liquid refrigerant should be charged from the suction port.
It is strictly forbidden to refill liquid refrigerant from the suction port during the working process of the unit.
The filling volume of the refrigerant must follow the amount of instruction that the equipment indicates.
After-sales service
After all the installation is finished and the cold room runs normally, Miracle service team is still there in case you have any needs for cold room operation.
If there is any problem with any parts of the cold room, we are responsible for it within the guarantee period.
