CascavilleThe 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 anti-collision flexible seal 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.
More and more people begin to build cold storage， and most people choose to use cold storage for cold storage construction. Why? Why do people choose cold storage for construction? What are the advantages of cold storage? The following is a detailed introduction.
Cold storage has good water tightness. Polyurethane rigid foam has low water absorption， good permeability to water vapor， foam holes， disconnected and closed porosity of more than %. It is a dense microporous foam material， which is more dense than air surface， and is not easy to permeate. It belongs to hydrophobic materials.
The ultrasonic town is a patented technology with a shaped energy cover， which increases the effective humidification amount by -% per hour. What are the reasonable aspects of the design of the quick freezing warehouse?
The controlled atmosphere warehouse is mainly used for the storage and processing of fruits. It can keep the low temperature of fruits in the cold warehouse and make the storage time longer. The walls of the cold warehouse are equipped with heat insulation panels， and the bottom is equipped with quick boards to prevent moisture and heat from the outside， Today， we"ll take you to know some precautions about how to store fruits in the cold storage: disinfection treatment before fruits are put into the fruit preservation cold storage: the cold storage should be disinfected before fruits are put into the fruit preservation cold storage. Sulfur is used for disinfection. Generally， kg of sulfur can be used for disinfection of cubic meters， and then use sawdust to ignite and close the doors and windows. Don"t open the doors and windows within two days. The storage volume of fruits should not be too large every time. It"s good if the daily purchase volume is about %.
Polystyrene foam: polystyrene foam is a new type of synthetic thermal insulation material. It is a kind of plastic with small density， light weight， strong heat insulation effect and excellent low temperature resistance. However， due to its cold shrinkage， it is not very convenient for installation.
Quality riskStretch perlite: stretch perlite is a kind of granular material with porous layout. The gap in it blocks out the heat. Professional cold storage installation， cold storage installation， cold storage construction， fruit fresh-keeping cold storage， medical cold storage， strict testing， quality assurance. Preferential activities are in progress. Welcome to consult. It has a good heat insulation effect. Then， the water vapor in the cold storage is easy to condense， and the water absorption of extensional perlite is particularly strong. If it absorbs a lot of water， its nature will be greatly reduced. Therefore， it is necessary to be careful to select extensional perlite as cold storage.
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，MatansasDesign and installation of vegetable fresh-keeping cold storage， and power protection shall be provided for the box and each power branch.
Install the temporary lighting facilities in the warehouse， install and arrange the construction electrical equipment， and do a good job in rain proof， moisture-proof， anti-collision， the cold storage will produce fixed length， width and thickness according to the needs of various cold storage projects. Generally， cm thick cold storage plates are selected for high and medium temperature cold storage. The requirements for cold storage engineering plates of low-temperature storage and quick-frozen storage will be higher. Professional cold storage installation， installation， construction， fruit fresh-keeping cold storage and medical cold storage ensure the quality， Guarantee service. Guarantee quality. Your satisfaction is our pursuit! Welcome to inquire. In this case， use cm or cm thick library board. When you budget the cold storage project， the foaming density of cold storage is per cubic meter
Job descriptionPrecautions for purchase and shipment when using the medical cold storage project you should pay attention to the density of the cold storage plate and the thickness of the steel plate when purchasing the cold storage plate. According to regulations， the speed must be strictly guaranteed during the purchase and shipment of products. If the temperature of the medical cold storage is about degrees， the opening time must be strictly within minutes. If the temperature of the medical cold storage is left and right degrees， the opening time can not be too high，MatansasInstallation price of small cold storage， strictly within minutes.
The machine room shall be kept clean and well ventilated， and the condenser shall be cleaned and masonry removed regularly to ensure the normal and stable operation of the unit.
Cold 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， small and medium-sized refrigerators are dominated by fully enclosed refrigeration compressors. Due to the small output power of the fully enclosed refrigeration compressor，MatansasWhat is a cold storage， 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， but it is easy to lead to the water consumption of the cold collection; Medium and ultra-low temperature refrigerators are dominated by seamless evaporation pipe slots， which is characterized by very good temperature control effect and moderate cold storage.
MatansasInstallation of box and operating device: the design of box shall be reasonable， and the appearance quality shall meet the requirements of beauty and practicality. All buttons， electrical switches， etc. shall be reliable， safe long-term cold storage installation， cold storage installation， cold storage construction， medical cold storage， old brand， price advantage and quality guarantee! Easy to identify and operate. The indicator light shall be simple and clear. The device and each switch shall be installed on the upper side outside the warehouse door， which is easy to operate， read data and not easy to be damaged， and shall be reliably fixed. The device box is installed on the door frame plate on the door opening side. The center line of the box overlaps the center line of the door frame plate. The bottom of the box is mm above the ground and is reliably fixed. The lighting lamp and door frame wire switch in the warehouse are installed directly below the device， and the height of the bottom edge of the switch box is about mm.
Frequently observe the operation state of the heart compressor of the cold storage equipment and its exhaust temperature. During the season change operation， pay special attention to the operation state of the system and adjust the liquid supply and condensation temperature of the system in time.
These 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.
