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.The structure of contemporary cold storage is in the development trend of prefabricated building cold storage. It is made into prefabricated components of cold storage including steam barrier and heat insulation plate to ensure on-site assembly. Its advantage is that the project construction is convenient, rapid and movable, but the project cost is relatively high.Kotka,If the wholesale equipment of the fresh-keeping storehouse is started again after a long-term suspension, the speed should be reduced at the initial stage of the wholesale opening of the fresh-keeping storehouse. Don't start too fast. It's better to reduce the speed at about - degrees every day. When the temperature drops to degrees, it should be maintained for a period of time. Don't regulate it at will.The cold storage belongs to a kind of refrigeration equipment. Compared with the refrigerator, its refrigeration area is large, but they have the same refrigeration principle. So how to maintain the cold storage every day. Today I'll introduce how to do a good job in the daily management and maintenance after the installation of the cold storage.Obilic,It is required to set up a special tally room (area), but indirect drainage shall be adopted. For the flushing (thawing) water drainage of each layer in the double-layer cold storage the drainage of the volatile cooler and the road drainage of the refrigerated warehouse storing food or drinks shall not be immediately connected with the sewage and wastewater pipeline system software, an exhaust valve equipment shall be set in front of the main riser for flushing (thawing) water drainage.The selection of equipment for the construction of equipment cold storage is closely related to the size, type and budget of the cold storage.

Cold storage plate features: good thermal insulation performance, light weight, high strength, corrosion resistance anti-aging, the speed should be reduced at the initial stage of the wholesale opening of the fresh-keeping storehouse. Don't start too fast. It's better to reduce the speed at about - degrees every day. When the temperature drops to degrees, it should be maintained for a period of time. Don't regulate it at will.When using the cold storage, try to keep the ground clean and professional cold storage installation,Honest service,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.Quick freezing storehouse is widely used. There are many kinds of temperature in quick freezing storehouse, and multi temperature or double temperature can be realized to meet the needs of different customers. Fault phenomena: unit current is large and voltage is too low; Loose wiring; The unit pressure exceeds the rated pressure; The oil separation core is blocked; Device failure; Host failure; Main motor fault; Fault phenomenon: the unit cannot be started and the fuse is broken; The temperature switch is broken; Loose wiring; Thermal relay of main motor acts; The thermal relay of cold storage fan motor acts; The transformer is broken; No power input (unit); Failure not eliminated (unit); The actuator is faulty.The combined cold storage door starts frequently or does not start for a long time, or stops before the storage temperature reaches.

- 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).Test conclusion,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.Does the unit location meet the relevant conditions? Whether the heat dissipation and pipe length can meet the requirements.Moreover, polyurethane does not produce harmful gas at high temperature.Kotka,Compression refrigerator is commonly used,KotkaDesign and installation of fruit and vegetable cold storage, which is mainly composed of compressor,KotkaProfessional cold storage installation, 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.There are two kinds of refrigeration in the cold storage group: immediate refrigeration and simple refrigeration.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.
