Families will also be equipped with some simple refrigeration devices. For refrigeration devices such as cold storage, it is very important to select materials with good thermal insulation. Cold storage is a better material selection, and in the production process of cold storage, there will be no condensation in the cold storage of the plant. Condensation inside the cold storage or inside the insulation layer is harmful. Irreversible damage or deformation occurs in the new external insulation, and the external surface temperature of the external wall changes sharply. For example, the insulation and sound insulation effects of polyurethane insulation board are relatively good, which can be used in many industries. As we all know, the cold storage has great requirements for the thermal insulation effect of building materials. If the thermal insulation effect of building materials is not good the cold storage will consume more energy during operation, and can not guarantee a good refrigeration effect. The performance of polyurethane insulation board meets the construction requirements of cold storage, so a large number of polyurethane insulation boards need to be used in the construction of general cold storage. Next, let's understand the physical properties of polyurethane insulation board.Judge the operating sound of the compressor, and carefully listen to the operating sound of water pump, cooling tower, compressor, fan and other equipment. In case of abnormal sound, timely warranty is required, so as to avoid greater damage to the compressor due to untimely warranty.Naukalpan,NaukalpanInstallation and maintenance of large cold storage,Do a good job of power failure early warning. The management personnel of the controlled atmosphere storage shall often pay attention to the notice of the local power department. In case of power restriction or line transformation, they shall do a good job in time. For sudden power equipment failure and artificial line, it is recommended to install power failure alarm, receive the alarm in time, and the loss will be reduced to a low level.Initial stage of cold storage equipmentGambia,The efficiency of the compressor is low, and the refrigerating capacity can not meet the load requirements of the warehouse: due to the long-term operation of the compressor, the cylinder sleeve, ring and other parts are seriously worn, the long-term cold storage installation, installation, fruit preservation, medical cold storage and other brand products, the designated products are complete, the quality is guaranteed, and the sealing performance will be reduced accordingly with the increase of the matching clearance, The gas transmission coefficient of the compressor will also be reduced, and the refrigeration capacity will be reduced. When the refrigerating capacity is less than the heat load of the warehouse, the temperature of the warehouse will drop slowly.The exhaust temperature of the compressor equipment is often. When the season changes and the temperature difference changes greatly, pay attention to it. If the machine is abnormal, it needs to be checked in time.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, and the height width ratio of floor drain water seal shall not be less than mm. The elevator shaft, electronic pit and other places convenient for drainage shall be provided with drainage and equipment to avoid backflow of water.Measure the winding resistance of the compressor and the insulation of the motor.Installation of cold storage, construction of cold storage, fruit preservation cold storage and medical cold storage have stable, safe, reliable and maintenance free performance. The technical level has reached the domestic level and the advanced level of similar international products. If there is a large amount of ice and water, it must be cleaned in time, and it must not be knocked during cleaning, small and medium-sized refrigerators are dominated by fully enclosed refrigeration compressors. Due to the small output power of the fully enclosed refrigeration compressorCold 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, 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, which is characterized by very good temperature control effect and moderate cold storage.A large number of personnel are not allowed to select goods in the warehouse. Close the warehouse door in time. When the warehouse door is opened pay attention to whether the air curtain is opened or the door curtain is placed properly. Turn off the lights when leaving the warehouse.The products stored in the medical cold storage project must be managed by color code, so as to avoid the problem of purchase errors. In the process of handling, it is also necessary to strictly follow the instructions.

At ordinary times, users should check the sealing degree of the gap of the cold storage, and notify the cold storage for maintenance in time if damaged parts are found.Respect for customers,Disadvantages of single-layer cold storage: large; The surface area of the external enclosure structure of the cold storage is large, so the amount of thermal insulation materials is large, and the dry consumption of cold food is also large; For the low-temperature warehouse,NaukalpanInstallation of cold storage Co., Ltd, the floor anti freezing treatment requires a large amount of work. When the cold storage is built at the water level, it is impossible to deal with it,NaukalpanWhere is a good place to install cold storage, which is easy to cause horizontal freezing and swelling.Because long-term wind and sun exposure is easy to cause line aging, short circuit, leakage and other accidents; After the fresh-keeping storehouse is installed and connected, it is necessary to start and debug the fresh-keeping storehouse, and adjust the value of the fresh-keeping storehouse to the appropriate temperature; The installation unit of fresh-keeping storehouse needs to provide the user of fresh-keeping storehouse with knowledge training on how to use and manage the fresh-keeping storehouse, as well as some after-sales training.It will still decrease. The humidification amount will decrease by % at degrees.Naukalpan,Preparation prepare the project planning of cold storage, and prepare the construction site and construction materials. All kinds of materials for cold storage construction are customized according to the needs of customers. Sort out the construction site that meets the requirements, transport all installation materials to the construction site check the material quality and model, and start the installation of cold storage after confirmation.Various construction materials, such as material certificate, test report and stage acceptance record, shall be carried out simultaneously with the project construction, carefully, timely, accurately and comprehensively reflect the whole process of production and construction, and actively cooperate with the owner in design change and technical negotiation.The equipment is built according to the application requirements of low-temperature distribution. It is reflected in the following points: a low-temperature hall, a closed platform, an electric sliding refrigerated door, and a platform height conditioning equipment (lifting channel) are built to complete & ldquo; Door to door & rdquo; Type loading and unloading operation has become a symbol of modern cold storage.
