eyeHow many kinds of cold storage,

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.Relative humidity maintenance of quick-frozen warehouse: humidification of quick-frozen warehouse is very important, from centrifugal humidification to high-pressure micro fog humidification, 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, return to the warehouse through the humidifier and isolate it from the outside air.eye,Another point is the ground maintenance measures in the wholesale of large fresh-keeping warehouses., Because the wholesale floor of large-scale prefabricated fresh-keeping warehouse is also a thermal insulation board, there will be a lot of ice on the ground in the process of use, so when cleaning these ice layers, you should pay attention not to beat them with a hammer or shovel, because it will damage the thermal insulation board on the ground. If the thermal insulation board is damaged it will affect the thermal insulation performance of the wholesale of fresh-keeping warehouse.There should be excellent drainage pipe standard around the warehouse, the soil temperature should be low, there should be interlayer under the cold storage, and maintain good natural ventilation. Maintaining dryness is very important for the cold storage. In addition, before the construction of the cold storage, the phase electricity of the relative volume shall be built according to the output power of the refrigeration unit. If the cold storage is water-cooled and radiating, the tap water pipeline shall be paved and the FRP cooling tower shall be built.Moussoro,During the installation of long-span top warehouse plate, if the supporting steel beam has been installed in the warehouse, the top warehouse plate and the supporting steel beam shall be fixed with pull rivets during the installation of each warehouse plate, and each top warehouse plate shall be riveted in two rows; If the lifting point type is adopted, the installation and construction of the lifting layout shall be realized before the installation and construction of the top silo plate, so as to ensure that each lifting point can be installed at the same time during the installation of the top silo plate; The lifting point shall ensure that there are at least two points along the width direction of each warehouse plate.These measures have achieved quite good results. Compared with several cold storages at a customer in Jining, the cold storages using their white materials have significantly lower power consumption than those using other white materials.In order to prevent damage to the cold storage, it is necessary to lay some foam on the floor of the cold storage tank.

Suggestions on the quantity of polyurethane cold storage insulation materials: cold storage investment is a long-term and profitable investment. A high quantity of hair can certainly reduce the initial investment, but it is necessary to grasp a certain limit and comprehensively consider the long-term energy consumption and initial investment, because the insulation effect of polyurethane cold storage insulation materials has a parabolic linear correlation with its bulk weight; A large number of studies have shown that the foam bulk density has better thermal insulation performance at ~ kg / cubic meter. Therefore, it is usually recommended that the number of thermostat refrigeratory outlets should be ~ square / ton.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, 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, Make the storage temperature drop and even.When outdoor air enters the cold storage body, it will not only increase the cold consumption of the cold storage, but also bring water into the warehouse. The condensation of water will lead to the building structure, especially the heat insulation structure, being damaged by moisture and freezing. Therefore, a moisture-proof and heat insulation layer should be set to keep the cold storage board building moisture-proof and air-proof performance and good sealing.supply,The polyurethane insulation board shall be connected by plug-in notch connection, because it has higher strength when connecting in this way.The ground insulation of small, medium and large cold storage is different, storage products and size of cold storage. Kuhua refrigeration reminds: ground insulation must be done, otherwise the temperature in the cold storage often fluctuates frequently due to poor insulation performance which affects the quality of stored goods. So, medium and large cold storage? How to do better?The spacing of pull rivets at inner and outer corners is mm and mm respectively; After the polystyrene library is installed, the wall panel joints shall be evenly sealed and decorated with silicone sealant.

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 coldExecutive standard,Kg to kg / m, and the steel plate thickness generally needs to be more than . mm to meet the standard. On the market, the main raw materials of special cold storage board for cold storage project are polyphenylene, polyethylene and polyphenylene grease. The density of thermal insulation material foamed by polyphenylene is thin,eyeCold storage installation and maintenance Telephone, and the thermal insulation coefficient is not very high; After a certain ratio of polyethylene, it can foam cold storage insulation materials with appropriate density and good thermal insulation effect, and has high load-bearing capacity; Polyphenylene resin has strong water absorption, but poor heat insulation. Therefore, the polyurethane sandwich board with very good performance belongs to the polyurethane sandwich board. Although it is slightly higher, the polyurethane board has very good thermal insulation performance and does not absorb moisture.The set values of various protective devices of the unit have been adjusted by the factory. Users are not allowed to change them at will.How to maintain the refrigeration compressor in the cold storage in order to prolong its service life and reduce the occurrence of faults in the use process. The refrigeration compressor in the cold storage needs regular maintenance. Here we introduce the maintenance of the compressor in the cold storage.eye,Installation of cold storage, construction of cold storage,eyeFood cold storage installation manufacturer, fruit preservation cold storage and medical cold storage have stable, safe, reliable and maintenance free performance. The technical level has reached the domestic level and the advanced level of similar international products. If there is a large amount of ice and water it must be cleaned in time, and it must not be knocked during cleaning, so as not to damage the ground and affect the service life of the cold storage.Emergency measures during the use of the medical cold storage project, it may also encounter power failure or power failure. In fact, most medical cold storage projects will be equipped with emergency equipment, so that the medical cold storage project can achieve the effect of normal power supply. Once the automatic temperature or humidity monitoring system is abnormal, the cold storage door should be closed in time, So as not to expose more air conditioners, resulting in corresponding problems in the quality of stored products. The medical cold storage project also has a self rescue system in time. If the temperature of the cold storage exceeds the limit, the system cooling system will also be turned on. When the temperature returns to normal, it will be automatically turned off.When opening and drilling is required for the top warehouse plate or wall plate, the internal and external setting out and positioning shall be carried out according to the drawing design requirements, return hole liquid inlet hole, water supply hole and drainage hole shall be opened with a hole opener. Construction treatment shall be carried out in time after opening and drilling, and the orifice shall be closed with foaming material or sealant to prevent air leakage and cold running; The door, vent and delivery port shall be decorated with wrapped edges and fixed with pull rivets, with a spacing of mm and mm outside.
