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 blockedInstallation of cold storage, construction of cold storage, 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.Tocoa,System blowdown: the standby air compressor is used. When the air compressor cannot be solved, the ammonia compressor can be used instead.Watertight polyurethane rigid foam has low water absorption, and state of foam pores. It is not connected with each other and the obturator rate is more than %. It is a dense microporous foam material, which is more dense than the surface of the air, and is not easy to permeate. It is an hydrophobic material.Ducos,The product shade warehouse is a warehouse location below ℃ and the sun cannot be straight. The humidity is % ~ % relative humidity, and there are corresponding strict requirements for the wall, ceiling, ventilation disinfection and epidemic prevention of the warehouse. The refrigeration system adopts full-automatic microcomputer electrical technology and does not need to be on duty. It mainly stores western and Chinese grass materials and instruments, and can monitor and record the temperature and humidity in the storage area.The cold storage board uses light polyurethane as the inner material of the cold storage board. The advantage of polyurethane is that the thermal insulation performance is very good. The exterior of polyurethane cold storage board is composed of SII, PVC color steel plate and stainless steel plate. The advantage of this is to prevent the temperature transmission of cold storage board due to large internal and external temperature difference, so as to make the cold storage more energy-saving and improve the working efficiency of cold storage.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, 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.

No 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.The wholesale evaporator of the fresh-keeping storehouse is used as a cold absorber for the wholesale of the fresh-keeping storehouse. The wholesale evaporator of the fresh-keeping storehouse is installed in the room of the cold-keeping storehouse, connected to the low-pressure end of the compressor, and has been installed for all kinds of cold-keeping storehouses with high prices nationwide for a long time. The cold-keeping storehouse is installed, constructed fruit fresh-keeping cold-keeping cold-keeping cold-keeping, medical cold-keeping cold-keeping cold-keeping, The refrigerant dissipated by the compressor is used for evaporation and gasification,TocoaWhere is it cold, and instantly becomes low temperature and low pressure through the throttling device, so as to achieve the purpose of refrigeration.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.reform,Install the electric control system. The electric control system of the cold storage mainly includes electric controller,TocoaHow to build fruit cold storage, electric door, lighting and other electrical equipment in the cold storage. The power supply of the cold storage is required to be stable phase line, and the power supply or backup power supply can be used as required. The circuit shall have reasonable discharge and corresponding protective measures.When hot ammonia defrosting or electric defrosting is selected as the cooling fan, professional cold storage installation, cold storage installation, cold storage construction, fruit preservation cold storage, medical cold storage, safety, the butt joint shall be filled with foaming material, and the mm wide color steel plate shall be sealed at the butt joint with pull riveting.

The product shade warehouse is a warehouse location below ℃ and the sun cannot be straight. The humidity is % ~ % relative humidity, and there are corresponding strict requirements for the wall, ceiling, ventilation, disinfection and epidemic prevention of the warehouse. The refrigeration system adopts full-automatic microcomputer electrical technology and does not need to be on duty. It mainly stores western and Chinese grass materials and instruments, and can monitor and record the temperature and humidity in the storage area.production costs,The drainage at the outlet of the cooling fan, the drainage of the volatile cooler and the road drainage of the refrigerated warehouse storing food or drinks shall not be immediately connected with the sewage and wastewater pipeline system software, an exhaust valve equipment shall be set in front of the main riser for flushing (thawing) water drainage.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, 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 cm thick plate is generally selected for the medium temperature controlled atmosphere storage, cm or cm 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, 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.Installation of box and operating device: the design of box shall be reasonable, and the appearance quality shall meet the requirements of beauty and practicality.
