Pay attention to the energy saving of the lighting system: the lighting of the cold storage should be considered comprehensively according to the area, height and warehouse temperature of the cold storage on the basis of safety science and rationality, from the perspective of energy saving and environmental protection. The lighting in the cold storage is concentrated in the working area.
Cold storage design step: the selection of cold storage refrigeration system the selection of cold storage refrigeration system is mainly the use of cold storage refrigeration compressor and air conditioning evaporator. Generally, small and medium-sized refrigerators are dominated by fully enclosed refrigeration compressors. Due to the small output power of the fully enclosed refrigeration compressor, the price is relatively cost-effective; Small and medium-sized refrigerators are generally dominated by semi closed refrigeration compressors; Semi closed refrigeration compressor is adopted for large and medium-sized refrigerated warehouses. When adopting ammonia refrigeration unit can also be considered. Because the output power of ammonia refrigeration unit is large and can be used for machine use, but the installation and management of refrigerated warehouses are cumbersome. When using the air-conditioning evaporator, the high-temperature cold storage uses the industrial cold fan as the air-conditioning evaporator. Its characteristic is that the temperature reduction speed is faster, but it is easy to lead to the water consumption of the cold collection; Medium and ultra-low temperature refrigerators are dominated by seamless evaporation pipe slots, which is characterized by very good temperature control effect and moderate cold storage.
Greensboro.Pressure leak test: the system pressure leak test is the same as the blowdown work sample, which is required to be carried out by air compressor.
Cold storage has good water tightness. Polyurethane rigid foam has low water absorption good permeability to water vapor, foam holes, disconnected and closed porosity of more than 95%. It is a dense microporous foam material, which is more dense than air surface, and is not easy to permeate. It belongs to hydrophobic materials.
.The equipment that needs to be installed in the warehouse and put into the warehouse shall be installed in place or placed in an appropriate position in the warehouse; The wall warehouse board shall be installed from the corner of the warehouse body, and the professional cold warehouse shall be installed. The cold warehouse shall be installed. The cold warehouse shall be constructed. The fruit fresh-keeping cold warehouse and medical cold warehouse shall have high pressure rating, good waterproof performance, fire and high temperature resistance, strong overload capacity, corrosion resistance, radiation protection and long service life. The corner shall be temporarily fixed with 0.5 color plate angle steel; When installing each wall panel, evenly apply two layers of foaming material on the joint surface of male and female groove, and apply one layer of foaming material when installing polystyrene wall panel. The blanking shall be uniform and continuous; After the wallboard is installed in place, pull rivets at the lap joint of the internal and external steel plates of the two wallboards for connection and fixation, and the rivet spacing in the warehouse should be 300mm; When connecting the library plate in the form of eccentric hook connection, the eccentric hook shall be loosened once before installation to ensure reliable locking during installation.
Cold storage design steps: selection and preparation of cold storage location. According to the application characteristics, cold storage can be divided into sexual cold storage, retail cold storage and large-scale cold storage. When large-scale cold storage starts to build a planting area with more centralized hand supply, factors such as superior geographical location and contact with the market should also be taken into account. The cold storage should be located in a cool place without sunlight and frequent warm air. Small and medium-sized cold storage is better
With the rapid development of modern commerce, the original cold storage for the purpose of product storage can no longer meet the rapid, accurate and small batch circulation needs of modern commodities. Therefore, the logistics center cold storage cold chain for the purpose of product distribution came into being and developed rapidly, playing a more and more important role in the commodity circulation chain. What are the characteristics of the rapid development of cold storage construction?
Core tip: in the cold storage project, and is not prone to failure, convenient use and management and long service life.
Pressure leak test: the pressure leak test of the fresh-keeping warehouse system is the same as that of the sewage blowing working sample, which is required to be carried out by air compressor. If ammonia compressor is used, a special one shall be designated and the exhaust temperature shall be strictly controlled. When high pressure is applied, the method of segmenting and reducing the pressure difference shall be adopted.
The equipment configuration is reasonable and the service life of the quick freezing warehouse is long. The reasonable equipment configuration of the quick freezing warehouse can greatly prolong the service time of the quick freezing warehouse. Some compressors are easy to be damaged when they work at full load for a long time, so we try to use screw parallel units. The great advantage of this unit is that it can turn on all equipment, just like the shift at work so that the compressor can work and rest in turn.
ranking.The floor of the cold storage shall be kept as close as possible during use
Step of cold storage design: selection and laying of cold storage thermal insulation materials. The use of cold storage thermal insulation materials must be adjusted to the time, which not only has excellent fire resistance,GreensboroInstallation of medical cold storage, with fixed length, total width and thickness. The cold storage plate with relative specification and model can be selected according to the installation of the warehouse body. The high and medium temperature cold storage generally adopts 10cm thick cold storage plate, 12cm or 15cm thick cold storage board is generally used for ultra-low temperature cold storage and freeze-cleaning cold storage; Another kind of cold storage can be sprayed with polyurethane spray paint and polyurethane foam, it is both waterproof and thermal insulation. Thermal insulation materials include polyurethane,GreensboroWhich is a good medical cold storage, polystyrene grease, etc. Polyurethane is non hygroscopic and has good fire resistance, but the cost is high; Polystyrene resin has strong water absorption capacity and weak fire resistance, but the cost is low.
1 - precautions for floor installation of cold storage: the floor shall be installed flat, the uneven part shall be leveled with materials, and the locking hook between the plates shall be locked to ensure that the warehouse surface is flat without hollow feeling. (note that if this drainage system is installed outdoors in the north, the drainage pipe shall be insulated).
We should implement regular maintenance and daily maintenance, professional cold storage installation, installation of cold storage, cold storage construction, fruit preservation cold storage, medical cold storage, large quantity,GreensboroQuick freezing cold storage installation manufacturer, fire resistance - Waterproof - high temperature resistance, strong and durable, safe and reliable, and maintain the operation rate of the compressor.

Greensboro.What should be considered in building a cold storage? In these aspects, food cold storage is a systematic project of artificial refrigeration to ensure food quality and reduce food decay in a low-temperature environment. Refrigeration technology affects the design of food cold storage, meets the needs of refrigeration technology, convenient production, energy saving and cost reduction. What problems should be considered in the construction of food cold storage?
Because polyurethane sheet has excellent thermal insulation performance, it can reduce the thickness of building envelope and increase indoor use area under the same thermal insulation requirements.
When installing the polyurethane insulation board, the adhesion between the panel of the polyurethane insulation board and the thermal insulation material is short and often high.
