Building a cold storage in an existing facility can be a challenging task, but with the right approach, it can be done successfully. When installing a cold storage in an existing building, it is important to consider the internal clear height, length, and width area to reserve the necessary space.
First, the building should have a clear height, length, and width area that can accommodate the cold storage installation. The insulation board of the cold storage should be 20cm smaller than the minimum net size of the wall in the building to avoid any partitions on the surrounding walls.
The fewer pillars there are inside the building, the more space there will be for the cold storage and goods to store.
For food cold storage, the temperature is usually between 0 ~ 10°C. The original ground needs to drop 20cm, with 10 cm for insulation panel and 10 cm for concrete. For low-temperature or ultra-low temperature cold storage, the original ground needs to be lowered by 30cm. If this is not possible, concrete with insulation can be used on the existing ground, which may result in a slope at the door of the cold storage or the entire cold storage area being higher than the original ground.
When building a large-scale cold storage that measures more than 6 meters in length, it is necessary to consider the weight of the roof of the cold storage and the lifting load of the original building. The load of one square meter on the top of the cold storage is around 20kg. You should take into account the weight of the refrigeration equipment, which is usually hoisted under the building structure. The weight of the equipment varies from 100-500kg depending on the model, and there are typically 8-10 hanging points that require sufficient strength to hold the equipment.
When building a large-area cold storage of over 300 square meters, it is important to ensure that the construction space on top of the cold storage has enough height and space for workers to carry out their tasks safely and effectively. The space should be at least 1.2 meters from the lowest point of the building to the top of the cold storage. For even larger cold storage areas exceeding 500 square meters, a minimum of 2 meters of space must be reserved to provide ample working space for materials and personnel.
The power supply needed for your cold storage will depend on the size of your facility and the refrigeration equipment used. We can estimate the required power based on volumes and local power system availability. Keep in mind that the power system of each country varies.
| Volume | 0 ~ 5℃ （380-420V/3 50Hz） | -18 ~ -25℃ （380-420V/350Hz） |
| 100 m³ | ≧10kW | ≧10kW |
| 100-200 m³ | ≧20KW | ≧20kW |
| 200-300 m³ | ≧25KW | ≧25kW |
| 300-400 m³ | ≧30KW | ≧30kW |
| 500-600 m³ | ≧40KW | ≧40kW |
| 600-700 m³ | ≧45KW | ≧45kW |
| 700-800 m³ | ≧50KW | ≧50kW |
| 1000 m³ | ≧60KW | ≧60kW |
Water consumption for the refrigeration equipment is generally not a concern. However, the water used by processing and cleaning workers inside the cold storage should be considered. For large-scale projects, an evaporative condenser may be needed, and a mixture of air and water is used.
We offer environmentally friendly refrigeration systems that use freon, such as R404A and R507A. For small amounts of refrigerants, local purchases are generally sufficient, but for larger amounts, international purchases may be considered.
