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 blocked
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.
Staya daroshiAs the hub of the refrigeration core， it plays the main role of repeated operation and work. After being compressed by the wholesale compressor in the fresh-keeping warehouse， the refrigerant changes from no pressure to high pressure and low pressure to a proportional pressure and low pressure. This high and low pressure can achieve the principle of refrigeration under the action of other parts.
With the increasing use of cold storage， cold storage board， is also increasing. Because cold storage is different from other ordinary cold storage it is important to the installation environment and temperature. Therefore， some small problems may be ignored during installation. According to the following understanding.
EvraxOn the basis of cold storage and preservation， the quick-frozen warehouse increases the regulation of gas composition， inhibits the respiration of fruits and vegetables， delays their metabolic process， better maintains the freshness and commercial quality of fruits and vegetables， and prolongs the storage period and shelf life of fruits and vegetables. Generally， controlled atmosphere storage of fruits can prolong the storage period by & mdash; Three times or more. OK， what is the standard of quick freezing warehouse?
Cold storage has good fire and flame resistance. 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， unlike flow burning and flashover like extruded board， which can effectively prevent fire spread. In particular， it can be closed as a whole after fire prevention treatment to form non combustible products.
Cold storage， compressor overload， lack of refrigerant， low pressure too low， excessive air intake， compressor jamming.
Requirements for refrigeration equipment in quick freezing warehouse: the strict sealing of quick freezing warehouse is obviously different from that of ordinary quick freezing warehouse. Therefore， how to seal the refrigeration equipment is the key. First of all， all through wall pipelines must be equipped with sleeves the frost flushing water return pipeline must be equipped with U-shaped bend water seal， and the main frost flushing and return pipeline outside the warehouse shall be equipped with air filling port to prevent the gas in the warehouse from being pumped out of the warehouse by negative pressure. In addition， due to the good sealing of the quick freezing warehouse， the set fluctuation range of the warehouse temperature should not be too large to prevent excessive positive and negative pressure from damaging the warehouse body.
Material requisition for the installation requirements of the assembly fresh-keeping warehouse: according to the engineering design and construction material list， the materials shall be sent to the accessories warehouse， and the materials and accessories models shall be carefully checked.
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.
A complete range of productsInstallation of unit electrical box: the unit electrical box shall be installed near the unit; Vertical installation. If the unit is installed on the top of the warehouse， the distance between the box bottom and the top of the warehouse must be & amp; gt; mm; The electrical box can be fixed on the building wall or on the angle steel frame.
With the rapid development of modern commerce the original cold storage for the purpose of product storage can no longer meet the rapid， accurate and small batch circulation needs of modern commodities. Therefore， the logistics center cold storage cold chain for the purpose of product distribution came into being and developed rapidly， playing a more and more important role in the commodity circulation chain. What are the characteristics of the rapid development of cold storage construction?
Regular oil discharge， descaling and air discharge: when there is a .mm thick oil film in the evaporator coil， in order to maintain the set temperature requirements， the evaporation temperature will decrease by ℃ and the power consumption will increase by more than ; When the scale on the water pipe wall in the condenser reaches mm， the condensation temperature will rise by ℃ compared with the original temperature， and the power consumption will increase. When the refrigeration system is mixed with non condensable gas and its partial pressure reaches .mpa， the power consumption will increase by about . It can be seen that it is cold
The ultrasonic town is a patented technology with a shaped energy cover， when selecting the site， priority should be given to the transportation convenience of the cold storage construction site， such as close to roads and railways. At the same time， the location of the cold storage should avoid large pollution sources and direct sunlight， to the current ultrasonic humidifier. The utility model has the advantages of small particles， uniform humidification， no freezing and blocking， and no dirty blocking. The air conditioning humidifier we produce is specially designed for all kinds of vegetable and fruit quick freezing warehouses， which is essentially different from other humidifiers in the market: fully closed circulation， that is， take the gas in the warehouse， return to the warehouse through the humidifier and isolate it from the outside air.
Staya daroshiThe foundation of cold storage is affected by low temperature， and the water in the soil is easy to be frozen. Due to the volume of frozen soil， the ground will be broken and the whole building structure will be deformed. If the damage is serious， it may even make the cold storage unusable. Therefore， in addition to the thermal insulation layer， the floor of low-temperature cold storage must be treated under the thermal insulation layer to prevent soil freezing. The bottom plate of the cold storage shall stack a large number of goods and pass through various loading， unloading and transportation machinery and equipment. Therefore， the structure of the cold storage plate shall be firm and have large bearing capacity. In low temperature environment， especially in the process of periodic freezing and thawing cycle， building structures are vulnerable to. Therefore，Staya daroshiWhich is a good place to install a small cold storage，Staya daroshiRefrigerator manufacturer， the structure of each part of the cold storage and the building materials of the cold storage should have sufficient frost resistance.
Cold storage design segmentation: several different partitions shall be reasonably planned and divided according to purpose and temperature. For example: processing room， sorting room， quick freezing room， refrigeration room， channel，Staya daroshiPreparation of vegetable fresh-keeping cold storage， unloading platform etc.
Before the acceptance and delivery of the project， the board surface shall be wiped clean. If there is any scratch， it shall be treated. There shall be no obvious scratch on the board surface.
