After adding flame retardant, polyurethane is a kind of flame retardant and self extinguishing material. If it is burned by fire, it can be carbonized, which can effectively prevent fire spread. In particular, it can be closed as a whole after fire prevention treatment to form non combustible products.The ground insulation of small, medium and large cold storage is different, which is closely related to the purpose, storage products and size of cold storage. Kuhua refrigeration reminds: ground insulation must be done, otherwise the temperature in the cold storage often fluctuates frequently due to poor insulation performance, which affects the quality of stored goods. So, what is the difference between the ground insulation of small, medium and large cold storage? How to do better?The medical cold storage has been widely used in the industry. For the use of the medical cold storage project, we must combine the performance of the product and store it according to the temperature and humidity required by the product. The automatic temperature box also needs to be used outside the product cold storage. At the same time, the management personnel must be familiar with the operation steps of the medical cold storage project.

According to the size and nature of the cold storage area and in combination with local regulations the construction form of food cold storage warehouse is to determine the plane layout based on the site, whether it is a single-layer or double-layer warehouse, and the structure is the selection of steel structure or reinforcement solidification. Cold storage capacity production process, refrigeration, product stacking, temperature, etc. are used to determine the size and location of the cold storage room, so that it can become a whole.The air washing and ventilation of the cold storage is in the long-term sealed LIUCai storage, and the carbon oxide is released due to the respiration of vegetables. If the accumulation is too high, it will have an adverse effect on the storage of vegetables. Therefore, ventilation device or air washing device is designed in the general warehouse.Simple refrigeration is based on the volatilization of refrigerant in the condenser of the cold storage, so as to cool the refrigerant, and then input the refrigerant into the box or building of the refrigeration equipment to cool the air according to the heat exchanger. This kind of refrigeration has slow cooling speed, large total heat conduction temperature difference and complex system software,RecithsaInstallation of large cold storage, such as brine ice making and cold storage with constant temperature requirements.technical service,Connect the refrigeration system. Wires and copper pipes shall be used to connect the refrigeration unit, electric control system and other components of the cold storage. The connecting pipes shall be closely connected, and corresponding thermal insulation and protection measures shall be taken.For the ground insulation of large cold storage, we can that the ground insulation of medium-sized cold storage is more complex than that of small cold storage and the ground insulation operation of large cold storage with larger warehouse area will be more complex. The common operations are as follows: first lay the ventilation pipe to prevent the ground from freezing drum cracking, then lay the moisture-proof and vapor barrier on the upper and lower sides of the extruded plate, then pour the reinforced concrete (generally at least cm thick), and then make the emery floor or epoxy floor according to the requirements. Among them, the XPS extruded plate is also laid according to the warehouse temperature. For example, the XPS extruded plate with thickness of ~ mm needs to be laid in the general low-temperature cold storage, while the XPS extruded plate with thickness of ~ mm can be laid in the high-temperature cold storage.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,RecithsaInstallation of fruit and vegetable fresh-keeping cold storage, safe, cold storage installation, cold storage construction, fruit preservation cold storage, medical cold storage, old brand, price advantage and quality guarantee!

The device and each switch shall be installed on the upper side outside the warehouse door, 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 mm 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 mm.

There are two kinds of refrigeration in the cold storage group: immediate refrigeration and simple refrigeration.resources,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 should be built in the room. cold storageWhen the actual scheme is determined, sometimes two defrosting schemes are adopted, and sometimes different schemes are combined. For example, the shelving, wall and top smooth pipes of the controlled atmosphere storage can be manually combined with the hot gas method. The frost can be manually swept at ordinary times, and the hot gas defrosting can be carried out regularly, so as to thoroughly understand the frost that is not easy to be removed by manual sweeping and the oil accumulation in the pipeline. Cold fan water flushing and hot gas method. Hot air combined with water can be used for defrosting if there is a lot of frost and the controlled atmosphere storage needs to be defrosted frequently.Fault phenomenon: high current or tripping during unit startup, and problems of user air switch; Input voltage is too low; The star angle conversion interval is too short (it should be ~ seconds); Hydraulic cylinder failure (no reset); Intake valve failure (too large opening or stuck); Loose wiring; Host failure; Main motor fault; TR time relay is broken (relay unit).Recithsa,Install the temporary lighting facilities in the warehouse, install and arrange the construction electrical equipment, moisture-proof, anti-collision, anti binding and other safety protection.Quick freezing storehouse is widely used.
