How to Choose a Good Design for Walk In Cold Rooms

Walk in Cold Rooms body design and selection of material

1.Structure of walk in cold rooms

Each walk in cold rooms use an independent cold room body, and the six sides for walk in cold rooms are designed with insulation structure separately, and separate the inside space from the outside space, this kind of type design will be easy for installation, also very convenient for relocating.

2. The design for walk in cold rooms body and external channel

Walk-in cold rooms door: There are sliding doors, hinge doors, electric doors, rolling doors, spring doors, etc according to the requirements of the site and the limitation of the channel. And the sliding door and hinged door are widely used. The advantage of the sliding door is no limit for the channel space. When the width of the passage is very small, the cold storage door can not be fully opened, but you need to move large equipment in, the sliding door can perfectly solve this problem. It can open at the most, but won’t waste any space for the passage.

Footstep for the walk-in cold rooms: Because the insulation layer is needed to walk-in cold rooms, so the bottom plate should be higher around 3cm-5cm than the floor because of the insulation layer. So there is a footstep between the walk-in cold rooms bottom plate and the floor, and this structure is very convenient for installation and relocation; Another way is to build the outside floor is the same height as the walk-in cold rooms bottom plate, some even use the same ground material to build on the insulation layer, which makes the walk-in cold rooms fixed on the ground, it can’t be moved and a little complicated for installation, but it’s convenient for transport the goods or tools to enter and exit the walk-in cold rooms.

3.The choice and design for walk in cold rooms panel

For the insulation material, most of the customers use environmentally friendly polyurethane foam material, some use polystyrene foam material, you can choose it as you like.

The selection of forming substrate plates: the commonly used foam-forming surface protection material mainly includes color steel plate, galvanized steel plates, and aluminum plates. For some situation that has quite high requirements or special application, it will use the stainless steel plates.

The selection of the thickness of the insulation layer:100mm thick insulation layer is widely used in the walk-in cold rooms that require a temperature higher than -22℃. For other cold room that requires lower temperature, the 150mm thick insulation layer is used for the temperature under -22℃ cold storage. If the cold storage temperature is lower than -30℃, it’s better to use the thickness for the insulation layer 200mm.

4. Anti-condensation design for walk in cold rooms door frame

Because there is the gap between the walk in cold rooms door and door frame, when the temperature difference for outside and inside of the cold storage reach 10℃, the moisture in the air will condense on the surface of the door frame, sometimes even flow to the ground. So it’s necessary to install the heating wire around the walk in cold rooms door frame, so as to no condensation situation happens even in humid weather.

Selection and design of refrigeration equipment for Walk in Cold Rooms

5. Calculation of heat load

In the walk in cold rooms, you should consider the heat sources that affect the storage temperature, the main heat sources are heat flow of the walk-in cold rooms body, goods heat flow, air exchange heat flow, evaporator and other heat flow, operator heat flow. Here I’ll explain them a little.

Heat flow of the walk-in cold rooms body: There is a temperature difference between the inside and outside of the walk-in cold rooms, the heat always transfers from high temperature to low temperature in the walk-in cold rooms. The main parameters that affect the heat flow are temperature difference, the surface area of the walk-in cold room’s body, and the heat transfer coefficient of the insulation material. The temperature difference and surface area of the walk-in cold room’s body are almost confirmed and stable, therefore choosing a good insulation material can reduce the heat flow of the walk-in cold room’s body.

Goods heat flow: Although the main function of the walk-in cold room is to store the material or semi-finished that have been cooled, it can’t avoid the high-temperature goods going in the walk-in cold rooms directly. In addition, the fruits and vegetables are still living when sending to the walk-in cold rooms, there is some heat generated by the respiration of the fruits and vegetables. So when you calculate the heat load, make sure to consider the heat flow for the goods, then you can design a good function walk-in cold rooms.

Air exchange heat flows: Fresh fruits and vegetables need to breathe and ventilate. There are major characteristics for using the walk-in cold rooms, it’s the frequently open and close cold room doors and balance windows. During the opening and closing, the gas exchange is unavoidable, then the hot air from outside enters the walk-in cold rooms and produces a certain amount of heat flow.

Evaporator and other heat flow:

Due to the forced convection of the fan motor of the evaporator, the storage temperature becomes even quickly, the heat and kinetic energy of the fan motor is completely converted into heat. So this evaporator fan motor heat should be calculated according to the operating time, normally 24 hours. At the same time, you should consider the heat produced by the electric defrosting and anti-condensation heating wire.

Operator heat flow:

This is a small factor for heat calculation because people do not work for a long time in the walk-in cold rooms, so you can ignore it for this condition.

6. Selection of the refrigeration compressor unit

For walk in cold rooms, we generally use a freon system. The walk in cold rooms is used frequently, so it has a high possibility for maintenance. Unless it’s particularly necessary, try to equip the independent condensing unit for walk in cold rooms, avoid the situation that several cold rooms share a refrigeration condensing unit.

And according to the info and requirements for each walk in cold rooms, you can choose different types of compressor, scroll,semi-hermetic type, and so on.

7. Selection of the evaporator/air cooler/blower

Selecting the air coolers with equivalent refrigerant capacity according to the calculated or estimated refrigeration cooling capacity, ensure it matches very well. The nominal refrigeration capacity and actual refrigeration capacity should be corrected and calculated according to the used evaporating temperature and the refrigerants you are using.

Walk in Cold Room Installation Case

How to Choose a Walk in Cold Room Location​

When the walk in cold room project is undergoing feasibility analysis, storage site selection and plan comparison should be carried out. Whether they walk in cold room location is selected reasonably or not is related to the construction speed of the project, infrastructure investment, and management and economic benefits after it is put into production. Therefore, the selection of the storage location should be based on nature, scale, construction investment, development plan, and other conditions of the cold storage, combined with the specific conditions of the proposed location, prudently proceed, and determine the best. In order to select the warehouse location correctly, the following basic conditions should generally be considered:

Economic basis

First of all, we must consider whether the local supply of raw materials, materials, energy, water, and other resources, as well as production collaboration (machine repair), freight, sales market, etc. have favorable conditions for building a database. The cold storage should be located in the production area, the concentrated supply area, or the main consumption area according to the nature of its use, and strive to load the reasonable flow of goods. In the overall layout, it should not be arranged in the upper reaches of the urban center and its drinking water source and should be selected as close to the town as possible.

Transportation

Convenient water and land transportation conditions must be considered, it is better to near the site to facilitate the transfer of goods in and out. For large and medium-sized cold storages, it is required that the site is near the ship’s docks or railways, and it is convenient to connect to nearby enterprises and strive to shorten the length of special railway lines. When selecting a site, it is necessary to learn about the possibility of constructing a dedicated line from the relevant department and obtain a certificate of conformity. Small and medium-sized cold storage is mainly transported by road, so the location should be as close to the road as possible to shorten the length of new roads outside the storage. Try to avoid building bridges, culverts, and tunnels.

Regional environment

There should be a good sanitary environment around the cold storage site, so when selecting the site, the grievance development plan of the local urban construction should be considered, and the sanitation of the surrounding environment of the storage site and possible future pollution trends should be understood. The storage site should be far away from factories and mining enterprises that produce harmful gases, smoke, radioactive substances, dust, odor, or seriously pollute groundwater. Try to choose the upwind zone of the industrial zone, and should be located upstream of the discharge outlet of the sewage treatment plant. Storage sites should not be located downstream of contaminated rivers or near infectious hospitals.

Geographical conditions

When selecting a site, the topography, geology, flood level, and groundwater level of the reservoir site should be carefully investigated or necessary survey analysis. The site selection should be based on the principles of saving land, occupying less farmland, not occupying good land, not demolishing or demolishing fewer private houses, and use wasteland and slope land as much as possible, and should not unilaterally emphasize the flatness of the storage site. Cold storage should not be built in the backfill layer, quicksand layer, collapse, and landslide zone, and should avoid faults and caves. The base endurance of the multi-layer cold storage should not be less than 0.15MPa per square meter, and the base endurance of the single-layer cold storage should not be less than 80kPa per square meter. The groundwater level must be below the freezing line.

Power supply conditions

The cold storage power supply belongs to the second type of load, which requires a reliable and stable voltage power supply. Efforts should be made to shorten the distance from the newly built high-voltage transmission line to the power connection point. If there is no power supply nearby, you should generally choose another storage location, regardless of self-installing power generation equipment. Therefore, when selecting a site, you should have a detailed understanding of the local power supply and line power supply, and you should contact the local electric power department to obtain a power supply certificate.

Water source conditions

If you choose a water-cooled condensing unit to walk in cold room, then you will use more water, so water source is one of the important conditions for determining the location of the walk in cold room. Therefore, there must be sufficient water sources near the walk in cold room site. The water source generally uses river water or deep well water. If the water source at the reservoir site is abundant, the cooling water can be used once, but in most cases, recycled water is used. Small walk in cold room uses tap water to recycle when there is no natural water source.

The Construction Process of Walk In Cold Rooms

Set the construction process of walk in cold room in China as an example, to introduce how we do it correctly. You can adjust them according to your country’s standards.

The outer protective structure of the walk in cold room adopts a large-span, light-weight steel door structure. Designed and manufactured according to national standards, and all prefabricated in the factory, all-metal components on site are connected by high-strength bolts and ordinary bolts. The roof is made of a self-waterproof profiled steel plate, and ventilation windows and roof ventilators are installed at the ridge.

Electrical Control Part

The electrical system of the walk in cold room is composed of cold storage lighting, door antifreeze heater, launch antifreeze heater, ceiling fan control, and temperature control system. The walk in cold room lighting is composed of a moisture-proof lamp, a lighting switch, and a 220/36 transformer: the transformer provides a safe and stable 36V power supply for the cold storage lighting, door antifreeze heater, and water antifreeze heater. (Note: If you require to walk in cold room lighting with indicator lights, the lighting will use a 220V lighting system.)

Door antifreeze heater, water antifreeze heater: The door antifreeze heater prevents the door from being frozen together with the freezer and cannot be opened at low temperatures.

The antifreeze heater prevents the defrost water from freezing in the sewer pipe so that the defrost water cannot be discharged.  Under normal circumstances, the low-temperature walk in cold room is prone to freezing, and heating wires should be used. The medium temperature walk in cold room is generally not required.

Ceiling evaporator control system: The evaporator is used for heat exchange. Generally, it is controlled by a temperature limit switch to ensure that the evaporator drops to a certain temperature and starts to run. At the same time, it is connected with the defrosting control to ensure that the evaporator stops running during the defrosting process. The defrost heater is used to remove the frost on the ceiling fan evaporator, thereby improving the efficiency of heat exchange. It is controlled by the defrost time controller. Its termination mode is the temperature termination mode controlled by the defrost limit temperature switch and the time termination mode controlled by the defrost time controller.

Construction Process and Specific Methods of Walk In Cold Rooms

The floor of the walk in cold room should be dry, flat, and hard. The surface is generally concrete, and sandy soil can also be used. The recesses are leveled with cement mortar. The cold storage should have a proper drainage location. If it is installed outdoors, users must set up rain sheds to ensure that the body of the assembled walk in cold room is protected from the sun and rain.

Walk in cold room door should be kept away from the wind and away from pollution sources. The floor elevation should be higher than the surrounding ground to prevent water from entering the reservoir on rainy days. When the mobile walk in cold room is installed indoors, the indoor clear height should be at least half a meter higher than the top surface of the walk in cold room roof. If the unit is placed on the roof of the walk in cold rooms, the clear height of the room should be 1.8m higher than the upper surface of the roof of the walk in cold rooms.
