St-John.There are several types of insulation materials. One is to produce and process plates with fixed shape and specification, fixed length, total width and thickness. Plates of corresponding specifications and models can be selected according to the installation of the refrigerator body. High and medium temperature refrigerators generally use 10cm thick refrigerator plates, and ultra-low temperature refrigerators and freeze-cleaning refrigerators generally use 12cm or 15cm thick refrigerator plates; Another kind of sprayed polyurethane foam can be sprayed immediately into the finished brick or concrete warehouse. After forming, it is both waterproof and thermal insulation. Thermal insulation materials include polyurethane, polystyrene grease, but the cost is high; Polystyrene resin has strong water absorption and poor fire resistance but the cost is low. The structure of modern cold storage is developing in the direction of dress matching architecture. They are made into prefabricated components including steam barriers and heat shields to ensure field assembly. Its advantage is that the project construction is convenient, fast and movable but the project cost is relatively high.
With the increasing use of cold storage, cold storage board, as an important structure of cold storage, is also increasing. Because cold storage is different from other ordinary cold storage, it is important to the installation environment and temperature. Therefore, some small problems may be ignored during installation. According to the following understanding.

Rivets shall be pulled and fixed at the internal and external lap joints of the steel plate, and the rivet spacing shall be 300mm; According to the design drawings, if there are supporting beams, columns and supporting steel frames in the warehouse the setting out and positioning shall be carried out and accurate and clear marks shall be made according to the requirements of the design drawings; Weld or install the support beam, column, support steel frame, etc., and the welded junction shall be moisture-proof and treated according to the drawing requirements.
Judge the operating sound of the compressor, cooling tower, compressor, timely warranty is required, so as to avoid greater damage to the compressor due to untimely warranty.
Installation of box and operating device: the design of box shall be reasonable and the appearance quality shall meet the requirements of beauty and practicality. All buttons, electrical switches, etc. shall be reliable, safe, long-term cold storage installation, cold storage installation, cold storage construction, fruit preservation cold storage, medical cold storage, 20-year-old brand, which is easy to operate, read data and not easy to be damaged, and shall be reliably fixed. The device box is installed on the door frame plate on the door opening side. The center line of the box overlaps the center line of the door frame plate. The bottom of the box is 1800mm above the ground and is reliably fixed. The lighting lamp and door frame wire switch in the warehouse are installed directly below the device, and the height of the bottom edge of the switch box is about 1400mm.
Transportation: before the installation of the fresh-keeping storehouse, check the number of storeboards of the fresh-keeping storehouse according to the delivery note. When loading and unloading the warehouse board, handle it with care, and lay an anti scratch layer on each layer of the warehouse board and the ground joint.
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.
Quality department.Compression refrigerator is commonly used, which is mainly composed of compressor, condenser, throttle valve and evaporation pipe. According to the way of evaporation pipe device, it can be divided into direct cooling and indirect cooling. Direct cooling the evaporation pipe is installed in the refrigerated warehouse. When the liquid coolant passes through the evaporation pipe, it will directly absorb the heat in the warehouse and cool down.
Goods in and out frequently, throughput
It is suitable for the freezing processing and storage of food, and manual refrigeration to keep the indoor temperature constant. The walls, the surface of the external wall of the cold storage is painted white or light color.
Floor insulation of small cold storage the structure of small cold storage is usually called surface, that is, the top, wall and ground are made of color steel plate / stainless steel with appropriate thickness of polyurethane and other insulation materials, because the loading and unloading of small cold storage is often handled manually rather than forklift. Of course, if the height of the warehouse is high and the forklift is required for warehousing, loading and unloading, the insulation board is not recommended for ground insulation, but the ground needs to be insulated separately like the ground insulation sample of medium-sized cold storage.

The selection of cold storage is very important for cold storage, because cold storage is different from ordinary cold storage. The temperature in cold storage is usually low, and the air temperature, humidity and environmental requirements are relatively high. When selecting cold storage, attention must be paid to the selection of cold storage with better temperature. If the selection of cold storage is not good, the temperature in the cold storage is difficult to, which is easy to cause the deterioration of products in the cold storage, or the refrigeration compressor in the cold storage often works, wasting more resources and increasing the cost.
There are two kinds of refrigeration in the cold storage group: immediate refrigeration and simple refrigeration.
