NaranjoGeneralThese are several very common cold storage materials. The use of these materials has greatly improved the thermal insulation and refrigeration performance of the cold storage, which makes people's retained items more convenient and reliable. With the continuous development of material technology, today's various cold storage materials emerge in endlessly, and the cold storage is different from each other. When purchasing we should make reasonable comparison and select products suitable for our own use needs and economic conditions.
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.
San-Vicente.The selection of thermal insulation material is important to the quality of controlled atmosphere storage; The selection of thermal insulation materials for the controlled atmosphere storage must be adjusted to local conditions, which should not only have good thermal insulation performance, but also be economical and practical. The thermal insulation materials are divided into several types. One is the plate processed into fixed shape and specification, with fixed length, width and thickness. The plate of corresponding specification can be selected according to the installation needs of the controlled atmosphere storage. The 10cm thick plate is generally selected for the medium temperature controlled atmosphere storage, 12cm or 15cm thick plates are generally selected for low-temperature controlled atmosphere storage and frozen controlled atmosphere storage. The other can be sprayed with polyurethane for foaming, and the materials can be directly sprayed into the built brick or concrete warehouse. After setting, it is moisture-proof and heat-insulating. The heat-insulating material plates include polyurethane polyphenylene grease, etc. Polyurethane does not absorb water and has good heat insulation. It is a long-term cold storage installation, installation, construction, fruit preservation and medical cold storage. Welcome to consult. But the cost is low; Polyphenylene resin has strong water absorption and poor thermal insulation, but the cost is low. The structure of modern controlled atmosphere storage is developing towards assembly, and the storage components including moisture-proof layer and thermal insulation layer are made to achieve on-site assembly. The point is that the construction is convenient, fast and movable, but the cost is relatively high.
The overall construction achievements of the cold storage project have been put into use, and the service life can reach 10 years.
.When the cold storage is used for the first time or shut down for a long time, it is strictly prohibited to stack goods in the warehouse. The warehouse must be slowly reduced to the required temperature. For the low-temperature warehouse, it needs to be cooled in stages to avoid sudden changes in the temperature difference inside and outside the warehouse, resulting in the warehouse body.
For the flushing (thawing) drainage pipe in the cold room with different temperature, an exhaust valve equipment shall be set before connecting the flushing (thawing) drainage pipe.
Install the temporary lighting facilities in the warehouse install and arrange the construction electrical equipment, and do a good job in rain proof,San-VicenteInstallation and maintenance of large cold storage, moisture-proof, anti-collision, anti binding and other safety protection.
With the increasing use of cold storage, cold storage board, as an important structure of cold storage, 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.
For those large-scale fresh-keeping warehouse wholesalers, if the equipment fails due to long-term neglect of maintenance, the loss can not be ignored. Therefore, we should do a good job in the maintenance of fresh-keeping warehouse wholesalers in the process of daily use.
Whether there is dirt on the condenser and poor heat dissipation will lead to too high condensation pressure of the refrigerator. In order to protect the compressor, press the black reset button on the pressure controller, and the machine can automatically resume operation.
Project scope.Connect the refrigeration system. Wires and copper pipes shall be used to connect the refrigeration unit, electric control system and other components of the cold storage. The connecting pipes shall be closely connected, and corresponding thermal insulation and protection measures shall be taken.
The refrigeration of cold storage pays more and more attention to the needs of environmental protection and energy saving. Professional projects include: cold storage installation installation of cold storage, cold storage construction, fruit fresh-keeping cold storage, medical cold storage and other related businesses. Merchants who hope to have this business please consider the wide scale of warehouse temperature control, the selection and placement of cooling equipment and the description of wind speed field, which are suitable for the cold storage needs of a variety of goods. Equipped with perfect storage temperature active detection, recording and active control equipment.
Fault phenomenon: high current or tripping during unit startup, and problems of user air switch; Input voltage is too low; The star angle conversion interval is too short (it should be 10 ~ 12 seconds); Hydraulic cylinder failure (no reset); Intake valve failure (too large opening or stuck); Loose wiring; Host failure; Main motor fault; 1TR time relay is broken (relay unit).
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,San-VicenteInstall fruit preservation cold storage, and the dry consumption of cold food is also large; For the low-temperature warehouse, it is impossible to deal with it, which is easy to cause horizontal freezing and swelling.
Inspection basis.Cold storage plate features: good thermal insulation performance, light weight, high strength,San-VicenteHow much does it cost to install a small cold storage, corrosion resistance, anti-aging, beautiful appearance.
Clean the condenser. The condenser is used as the heat dissipation and condensation of the compressor. Because it works in the outdoor environment, in the face of nature and for a long time, the condenser will be covered with a lot of dust and other foreign matters. These dust are firmly attached to the fins. If it is not handled manually, it is difficult to fall off. It can be diluted with cleaning agent according to a certain proportion, and evenly sprayed on the fins with a spray can. After waiting for 5 minutes, it can be washed with clean water. If it is still not clean, the above can be repeated until the fins are clean.
The 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, unloading and transportation machinery and equipment. Therefore, especially in the process of periodic freezing and thawing cycle, building structures are vulnerable to. Therefore, only with sufficient cold storage installation skills can we ensure that the cold storage is more energy-saving and power-saving after installation, and is not prone to failure, convenient use and management and long service life.
What should be considered in building a cold storage? In these aspects, food cold storage is a systematic project of artificial refrigeration to ensure food quality and reduce food decay in a low-temperature environment. Refrigeration technology affects the design of food cold storage, meets the needs of refrigeration technology, convenient production, energy saving and cost reduction. What problems should be considered in the construction of food cold storage?
There are many application scenarios of cold storage, which are different. For a long time, it provides various cold storage installation, cold storage installation, cold storage construction, fruit preservation cold storage, medical cold storage, on-site settlement, honest operation, and has offices all over the country for long-term cooperation. Different purposes, functions and designs, so what needs to be understood in cold storage design?
