To do a good job in cold storage design, you need to be well prepared and various mature cold storage design solutions. In the process of designing the cold storage, factors such as the user's use requirements and installation location must be taken into consideration to ensure a better fit. Future use needs. Reduce failures and increase efficiency. Designing the cold storage in mind, below we have to prepare a variety of cold storage design conditions.
The size of the cold storage should be designed according to the high amount of zui that is to be stored in the year-round. This capacity is calculated based on the volume that the stored product must occupy in the cold storage, plus the inter-row aisle, the space between the stack and the wall, the ceiling, and the space between the packages. After determining the cold storage capacity, determine the length and height of the cold storage.
1. Various considerations for cold storage design
The cold storage design must also consider the necessary ancillary buildings and facilities, such as workshops, packaging and finishing rooms, tool magazines and loading docks. According to the nature of use, cold storage can be divided into three types: distributed cold storage, retail cold storage, and productive cold storage. The production cold storage is built in a production area where the supply of goods is concentrated, and factors such as transportation convenience and market are also considered. There should be good drainage conditions around the cold storage, the groundwater level should be low, and there should be a compartment under the cold storage, and keep the ventilation well. Keeping dry is very important for the cold storage.
2. Preparation of cold storage design materials
The selection of cold storage insulation materials must be adapted to local conditions, and it must have good thermal insulation properties and be economical and practical. The structure of the modern cold storage is developed into a cold-formed warehouse, and a cold storage component including a moisture-proof layer and a heat-insulating layer is formed to achieve on-site assembly. The advantage is that the construction is convenient, fast, and movable, but the cost is relatively high.
3. Cooling system in cold storage design
The choice of cold storage cooling system is mainly the choice of cold storage compressor and evaporator. Under normal circumstances, the small cold storage is mainly based on fully enclosed compressors. Medium-sized cold storage is generally dominated by semi-closed compressors; large-scale cold storage uses semi-closed compressors, but cold storage design and cold storage installation and management are cumbersome.
4. Compressors considered in cold storage design
In the refrigeration unit of the cold storage, the capacity and the number of the refrigeration compressor cold storage equipment are configured according to the large heat load of the production scale and considering the respective cooling parameters. In actual production, it is impossible to be completely consistent with the design conditions. Therefore, it is necessary to select and adjust according to the actual production conditions to determine the capacity and quantity of compressors that are reasonably put into operation, in order to complete the refrigeration task of the required cold storage with the low consumption and the appropriate conditions.
When selecting and adjusting the compressor in the design and installation of the cold storage , the following points should be followed:
1. Select the compressor according to the heat load of the cold and the cooling capacity of the evaporator, so that the refrigeration capacity of the compressor that is put into operation is compatible with the heat load and the refrigeration capacity of the cold storage refrigeration equipment.
2. When the required evaporation temperature is high and the actual condensation temperature is high, bipolar compression refrigeration is required. Generally, the compression ratio is equal to 8 as the boundary. When the compression ratio is less than 8, single-stage compression is adopted; when the compression ratio is greater than or equal to 8, the bipolar compression is adopted.
3. Make each machine operate with only one heat load of evaporation temperature as much as possible, so that a better cooling effect can be obtained.
4. Bipolar compressor or bipolar compressor unit can reasonably adjust the volume ratio of high and low pressure compressors according to intermediate temperature, condensation temperature, evaporation temperature and so on.
