Henri de Castries Refrigerated drugsAssembly scheme of

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,Henri de Castries Cold storage unit installation, 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 coldNo matter whether the food cold storage or quick-frozen storage is in use, it is inevitable that there will be various small faults. Don't be nervous when there are problems. You can find or eliminate problems according to the knowledge taught today.Henri de Castries ,As 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.Danfoss thermal valve is adopted for the thermal valve of the cold storage, with guaranteed quality; Due to the high temperature requirements of the cold storage and the high degree of automation and regulation of the temperature, the temperature system of the cold storage adopts microcomputer full-automatic, does not need special people to operate, and can be remotely controlled. When the temperature exceeds the specified range, it will automatically alarm, which is of great significance to the proper preservation of the cold storage.Drobak,Quick freezing storehouse is widely used. There are many kinds of temperature in quick freezing storehouse,Henri de Castries Cold storage according to installation, and multi temperature or double temperature can be realized to meet the needs of different customers. Fault phenomena: unit current is large and voltage is too low; Loose wiring; The unit pressure exceeds the rated pressure; The oil separation core is blocked; Device failure; Host failure; Main motor fault; Fault phenomenon: the unit cannot be started and the fuse is broken; The temperature switch is broken; Loose wiring; Thermal relay of main motor acts; The thermal relay of cold storage fan motor acts; The transformer is broken; No power input (unit); Failure not eliminated (unit); The actuator is faulty.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.The equipment that needs to be installed in the warehouse and put into the warehouse shall be installed in place or placed in an appropriate position in the warehouse; The wall warehouse board shall be installed from the corner of the warehouse body, and the professional cold warehouse shall be installed. The cold warehouse shall be installed. The cold warehouse shall be constructed. The fruit fresh-keeping cold warehouse and medical cold warehouse shall have high pressure rating, good waterproof performance, strong overload capacity corrosion resistance, radiation protection and long service life. The corner shall be temporarily fixed with . color plate angle steel; When installing each wall panel, evenly apply two layers of foaming material on the joint surface of male and female groove, and apply one layer of foaming material when installing polystyrene wall panel. The blanking shall be uniform and continuous; After the wallboard is installed in place, pull rivets at the lap joint of the internal and external steel plates of the two wallboards for connection and fixation, and the rivet spacing in the warehouse should be mm; When connecting the library plate in the form of eccentric hook connection, the eccentric hook shall be loosened once before installation to ensure reliable locking during installation.

Whether the water pump works normally and whether the moldy switch is effective. In case of abnormality timely handle the overhaul and maintenance of the refrigeration compressor in the cold storage: generally, the refrigeration oil and drying filter shall be replaced times after the operation of the cold storage equipment. Replacement after half a year. Depending on the circumstances.After startup first listen to whether the sound of the compressor is normal, and see whether the condenser and cooling fan operate normally.Initial stage of cold storage equipmentHighly recommended,The service life of the cold storage depends on the quality of the refrigeration equipment, but it also has a great relationship with the proper daily management and maintenance after the installation of the cold storage. Many times, people often ignore the latter point. In daily life, as long as we maintain and maintain the cold storage regularly, we can greatly improve the service life of the cold storage and reduce the cost.Acid disinfectant can be used for mold removal and disinfection of quick-frozen warehouse.Feasibility of the design scheme: the design of the quick-frozen warehouse can not be taken for granted. Many restrictive factors should be considered. In practice, a reasonable design scheme should be given according to local conditions. For example, the large-scale quick-frozen warehouse I built for my family should be refrigerated with ammonia in theory, because the refrigeration capacity of ammonia refrigeration is large, and I found that it is cheap to replicate cold through actual field investigation.

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.Total quality management,In the low temperature environment, especially in the periodic freezing and thawing cycle, the building structure is also vulnerable to. Therefore, the building materials of the cold storage and the structure of each part of the cold storage should have sufficient frost resistance.The air conditioning warehouse is equipped with standby power supply. After eliminating the line and load problems, it is the maintenance of external irresistible power lines. If the refrigerated goods in the air conditioning warehouse are expensive or vulnerable to temperature changes, it can be considered to equip the air conditioning warehouse with standby power supply to ensure the operation of refrigeration equipment in the cold storage in a short time after power failure. Large air conditioning warehouses can be considered to be equipped with generator sets, dual mains power can be used.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 structure of contemporary cold storage is in the development trend of prefabricated building cold storage. It is made into prefabricated components of cold storage including steam barrier and heat insulation plate to ensure on-site assembly. Its advantage is that the project construction is convenient, rapid and movable, but the project cost is relatively high.Operating the unit: regularly observe the oil level and oil return of the compressor and the cleanliness of the oil. If the oil is dirty or the oil level drops, it shall be solved in time to avoid adverse effects.Polyurethane refrigeration board uses light polyurethane as the internal material of refrigeration board. The advantage of polyurethane is very good heat insulation. The exterior of the cold storage is composed of SII,Henri de Castries Professional cold storage installation, PVC color steel plate and stainless steel plate. The advantage of this is that it can prevent refrigeration, and the temperature will disperse, which makes refrigeration more energy-saving and improves the working efficiency of refrigeration.
