The butt joint between the top warehouse plate and the end of the top warehouse plate shall be treated to prevent air leakage and cold running. After all the top warehouse plates are installed, the butt joint shall be filled with foaming material, and the mm wide color steel plate shall be sealed at the butt joint with pull riveting.Thermal insulation rigid polyurethane has low thermal conductivity and good thermal performance. When the density of rigid polyurethane is ~ kg / m, which is the lowest among all thermal insulation materials at present.San josito, in order to keep the temperature fluctuation in the warehouse small, it is more necessary to store the temperature and time of goods entering and leaving the warehouse. Introduction to KFC refrigeration: logistics refrigerators with frequent incoming and outgoing goods and large throughput, usually set up a special tally area according to business needs, and the temperature of the tally area is generally ~ ℃. In addition, a transfer room will be set in the logistics cold storage to avoid the loss of refrigeration capacity caused by frequent opening and closing of the cold storage door, or unqualified temperature and serious frosting.Compression refrigerator is commonly used, which is mainly composed of compressor, 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 throttle valve and evaporation pipe. According to the way of evaporation pipe device, it will directly absorb the heat in the warehouse and cool down.Rocha,If there is more air or refrigerant oil in the evaporator, the heat transfer effect will be reduced: once more refrigerant oil is attached to the inner surface of the evaporator heat transfer tube, the heat transfer coefficient will be reduced. Similarly, if there is more air in the heat transfer tube, the heat exchange area of the evaporator will be reduced, the heat transfer efficiency will be significantly reduced and the decline rate of warehouse temperature will be slowed down.Technical assurance measures for the installation of cold storage: during production in the production workshop, the production shall be carried out in strict accordance with the operation rules specified in ISO quality operation, self inspection and inspection application shall be carried out to ensure that the factory pass rate is, and unqualified products are not allowed to leave the factory.For the flushing (thawing) drainage pipe in the cold room with different temperature,San jositoFood cold storage installation manufacturer, an exhaust valve equipment shall be set before connecting the flushing (thawing) drainage pipe.

Operating the unit: regularly observe the oil level and oil return of the compressor and the cleanliness of the oil. If the oil is dirty or the oil level drops, it shall be solved in time to avoid adverse effects.Vibration shall be prevented during the whole operation of the refrigeration unit. In addition to the abrasion of the lifting mechanical equipment, vibration will continue to cause loosening or cracking of the upper connecting pipe of the generator unit. If abnormal noise is found during the whole operation of the equipment, it shall be shut down for inspection before operation. The maintenance functions of the refrigeration unit have been set and do not need to be adjusted.Other aspects: in the design process of food cold storage, it is also necessary to consider the cooperation between the cold storage and on-site fire fighting, ventilation, water and electricity systems. It should meet the requirements of safety, science and environmental protection. When designing and installing the cold storage, the drainage problem must be considered, and the following points should be paid attention to during redesign and installation.Excellent quality,The machine room of ammonia refrigeration system shall be equipped with exhaust assembly; The exhaust fan shall adopt anti motor. When the power supply is cut off due to unexpected refrigeration, it shall be able to ensure the reliable power supply of the exhaust fan. The overload protection of the exhaust fan should be applied to the signal alarm system without directly stopping the exhaust fan. The button box of the exhaust fan shall be concealed in the wall outside the ammonia compressor room.Stretch perlite: stretch perlite is a kind of granular material with porous layout. The gap in it blocks out the heat. Professional cold storage installation, cold storage installation, cold storage construction, fruit fresh-keeping cold storage, medical cold storage, strict testing, quality assurance. Preferential activities are in progress. Welcome to consult. It has a good heat insulation effect. Then, the water vapor in the cold storage is easy to condense, and the water absorption of extensional perlite is particularly strong. If it absorbs a lot of water, its nature will be greatly reduced. Therefore it is necessary to be careful to select extensional perlite as cold storage.Before the acceptance and delivery of the project,San jositoDesign and installation cold storage installation company, the board surface shall be wiped clean. If there is any scratch,San jositoInstallation of small fruit cold storage, it shall be treated. There shall be no obvious scratch on the board surface.

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 storageMarketing Department,In the cold storage project, the selection of cold storage is related to the overall operation of cold storage in the future. The selection of high-quality cold storage is conducive to the use and maintenance of cold storage. This requires us to inquire more about the warehouse board for cold storage engineering. Before the construction of cold storage project, we should first realize the temperature requirements of cold storage and the importance of cold storage to cold storage. Because the cold storage project has high environmental requirements such as temperature, attention should be paid to the performance and material of the cold storage board when selecting the cold storage board.In case of fault alarm shutdown of the unit, first press the stop button of the unit (the alarm light will go out), and then the cause of the fault. It is not allowed to start the unit forcibly until the fault is eliminated.When installing polyurethane insulation board ensure that its surface is smooth and flat without scratch and warpage.San josito,Disadvantages of multi-layer cold storage: the vertical transportation volume of the warehouse is large, and the goods in and out and operation management are not as convenient as single-layer cold storage; With the development of the floor load capacity, the floor area ratio of each cold room is low; When the multi-storey cold storage is built on the foundation with poor ground resistance, the foundation construction is complex. High cost; When prefabricated components are used, large construction equipment is required and the construction period is long.The three-dimensional automatic cold storage adopts a computer, which can complete the loading, unloading and stacking in the storage, the control of storage temperature and the operation of refrigeration equipment.Requirements for the cold storage time of the device: the cold storage of the refrigeration system using ammonia as refrigerant shall be supported in the place with low population density around.
