During the cold storage commissioning, special personnel shall be assigned to ensure that the surface of the cold storage plate shall reflect evenly without condensation and cold running; Sealing conditions of joints and holes; Whether the warehouse door and delivery port are not tightly sealed, and timely deal with the problems of insulation and seal failure such as degumming and air leakage.Some cold bridge prevention measures shall be taken at the joints between polyurethane insulation boards.Old harbour,The selection of the refrigeration system of the controlled atmosphere storage is mainly the selection of compressor and evaporator. The refrigeration system is the core of the controlled atmosphere storage, which is mainly composed of compression system, condensation system, evaporation system and regulating valve. In addition, there are auxiliary parts such as fan, duct and instrument. The whole refrigeration system is a sealed circulating circuit in which the refrigerant circulates, The compressor is the heart of the refrigeration system, which promotes the circulation of refrigerant in the system. The function of the condenser is to remove the heat from the compressed gaseous refrigerant and condense it into liquid refrigerant; The cooling methods of the condenser include air cooling, water cooling and the combination of air and water. Air cooling is only used in the refrigeration equipment of small-scale air-conditioned storage. The role of the evaporator is to provide cooling capacity to the air-conditioned storage. The evaporator is installed in the air-conditioned storage. The blower blows the cooled air to all parts of the storage. The air duct of large-scale air-conditioned storage is commonly connected with the evaporator to extend the air supply distance, 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,Old harbourInstallation price of vegetable cold storage, ring and other parts are seriously worn, the long-term cold storage installation, installation, construction, fruit preservation, medical cold storage and other brand products, the designated products are complete, the quality is guaranteed, 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.Split,The average service life of rigid polyurethane insulation structure with stable quality, long service life and high comprehensive cost performance can reach more than years under normal use and maintenance conditions. Under the normal service conditions during the service life of the structure, it will not be affected by drying, or electrochemical corrosion, fungi or algae or rodents.Whether the parameters of refrigeration equipment are consistent. When the cold storage leaves the factory,Old harbourCold storage board installation, the temperature and temperature difference parameters of the cold storage shall be customized according to the user's requirements. After understanding the technical parameters of the cold storage set the parameters on the refrigerator. During use, the air humidity is high and the defrosting interval is long. The common cold storage boards of cold storage include mm, mm, mm, mm and mm polyurethane thermal insulation boards, color steel tiles, stainless steel plates, salt thick steel plates, embossed aluminum plates, polyurethane spraying,Old harbourHow to charge for the installation of cold storage, etc. on both sides or single and double sides, more general color steel tiles are produced and processed into hidden grooves, which have light weight, high compressive strength, good fire resistance, corrosion resistance and aging resistance, The cold storage board is simple and convenient to assemble, and is a wide range of raw materials selected for the heat insulation and heat preservation of the cold storage. The cost of stainless steel plate and salt plate increases, and it is also easy to deform and damage the appearance.The medical cold storage has been widely used in the industry. For the use of the medical cold storage project, the management personnel must be familiar with the operation steps of the medical cold storage project.

Fault phenomenon: fan motor overload, fan deformation; Fan motor fault; Fan motor thermal relay fault (aging); Loose wiring; Cooler blocked; Large exhaust resistance. Cold storage fault phenomenon: dryer does not operate, compressor line is disconnected, fuse is blown thermal relay acts, high voltage switch acts, compressor is locked, line is falsely connected or loose fault phenomenon: it stops in a short time after drying, ambient temperature is too high, condenser is blockedFor the installation of refrigeration unit, oil separator shall be installed for semi sealed or fully sealed compressor, and an appropriate amount of oil shall be added in the oil. When the evaporation temperature is lower than - ℃, gas-liquid separator and an appropriate amount of refrigeration oil shall be added.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.property right, long-term continuous operation will inevitably lead to equipment aging so reasonable maintenance is particularly important.Polyurethane foam: This is also a very common cold storage material. It has strong thermal insulation effect and strong mechanical strength. Now it is widely used and has a good application prospect.

Compression refrigerator is commonly used. It is mainly composed of compressor, it directly absorbs the heat in the warehouse and cools down.manufacturer throttle valve and evaporation pipe. The evaporation pipe is installed in the refrigeration warehouse. When the liquid coolant passes through the evaporation pipe condenser,The combined cold storage does not cool or the cooling effect is poor. Check whether the condenser of the refrigerator is dirty. Whether frost is too thick on the evaporator in the warehouse. Check whether the refrigerant is leaking (apply soapy water to the pipeline connection, and if bubbles are generated, it indicates that the refrigerant is leaking). And ask the combined cold storage engineering personnel to supplement the refrigerant and deal with the leakage. Check whether the sealing of the combined cold storage door is intact and eliminate it. Whether the refrigerator of the combined cold storage works. Whether the parameter setting of the computer controller of the cold storage is correct, and reassemble the cold storage door for installation. Check whether the cooler in the cold storage fails and replace it. Whether there is enough clearance for stacking articles in the warehouse and dredge them.Reasonably design the division of fresh-keeping warehouse, such as cold storage room, freezer room, machine room, aisle, transportation platform, etc; The fresh-keeping storehouse shall be built indoors to avoid excessive temperature and poor refrigeration effect. If it is set outdoors, a sunshade shall be built; Wires shall not be outdoors,All wiring shall be neat. All switches and keys shall be opened and closed sensitively, reliably and accurately. Special connectors shall be used for wiring, and power protection shall be provided for the box and each power branch.Old harbour,As a coolant, make it evaporate under low pressure and mechanical conditions to absorb the heat in the storage, so as to achieve the purpose of cooling.Some cold bridge prevention measures shall be taken at the joints between polyurethane insulation boards.General quick-frozen warehouses are mostly cooled by refrigeration mechanisms, and those with very low gasification temperature are used as coolant to evaporate under low pressure and mechanical conditions, so as to absorb the heat in the warehouse, so as to achieve the purpose of cooling and reduction.
