How to choose Cold storage air cooler and pipe selection

                          China cold room introduction The choice of cold storage or cold storage is good, and many friends are very uptight. Some confuse the air cooler with the air-cooled air-conditioning unit. Some do not know how to choose. What is the best choice for the cold-storage air-conditioning system?Generally speaking, we do recommend the use of air coolers for easy installation. If it is a large-scale cold room, when the exterior height of the cold storage is high, the internal machine adopts a row tube, so the installation is inconvenient and has a certain potential safety hazard. The chiller is easy to dismantle and is suitable for use in high temperature storage.Low-temperature cold storage or ultra-low temperature cold storage, refrigeration encyclopedia recommended to use the row of tubes, the market to do low-temperature cold storage, using a row of tubes out of many machines. Considering from a long-term perspective, the use of platoon pipes makes the cooling capacity in the cold storage even and saves energy and power, but it also has certain disadvantages. The price is relatively high, and it is inconvenient to install compared to chillers.It is perfectly possible to use a chiller at a low temperature of minus 18 degrees or minus 25 degrees, and there is no need to worry about the frosting problem. However, if it is a cryogenic cold storage, it is recommended to use a platoon pipe. Of course, this is closely related to the budget of the cold storage owners.Cold storage chooses cooling fan or row pipe from the following points of view1. From the cooling effect:The cooling effect of the pipe is slightly better than that of the cooling fan. The heat conduction of the pipe is faster than the cooling fan, especially the aluminum row, so the general high-temperature library can be used with a cooling fan. We recommend using the pipe for low temperature or ultra-low temperature storage. , And because the distribution of the pipe is relatively balanced, so the cooling capacity is relatively uniform, can achieve the effect of energy saving.2. From the scope of application:Because the row pipe is a pipe type evaporator, it can strongly lock in moisture. Because the air blower is a wind blower, it will evaporate water, making the product in the store dry and wither. Therefore, it is suitable for products with a lot of water, such as pipe line. Ice cream ice cream, fruits and vegetables, etc., and the chiller, then apply to dry goods, dried fresh, frozen meat, etc., so generally choose to install pipe or fan, mainly to see which match your product more.3. From the height of the library:If it is a large-scale cold storage, and the cold room library has a relatively high external height, it is recommended that the internal unit use a cooling fan. If the exhaust pipe is used, the installation is very inconvenient and there is a certain potential safety hazard. The chiller is more convenient to use in high warehouses because of disassembly and assembly.4. From the perspective of economic adjustment:In general, due to the cooling performance and production cost of the pipe, the price of the pipe is generally slightly higher than that of the cooling fan, especially the aluminum pipe. However, the long-term operation of the cooler bank consumes more power than the aluminum pipe storage. Whether it is a fan or a fan, it is still based on the budget.  

What is a blast freezer

What is a blast freezer?Quick-freezing cold storage refers to a method of quickly freezing food through its maximum ice crystal generation area and quickly freezing when the average temperature reaches -18 ° C.The temperature of the freezer is generally -15 ° C to -35 ° C. Mainly used for low-temperature fast freezing of food, medicine, medicinal materials, chemical raw materials and other items. With fast cooling, good freshness and so on.The so-called rapid freezing refers to the method of quickly freezing food through its maximum ice crystal generation area and quickly freezing when the average temperature reaches -18 ° C.During the freezing process, various changes occur in food, such as physical changes (volume, thermal conductivity, specific heat, dry loss, etc.), chemical changes (protein denaturation, discoloration, etc.), changes in cell tissue, and biological and microbial Changes, etc.The characteristic of fast frozen food is that it maintains the original nutritional value and color and aroma of the food to the maximum extent.That is to say, during the freezing process, a quick guarantee must be kept to ensure that the above-mentioned various changes in food have reached the greatest reversibility.Large-scale quick-freezing warehouses are all part of cold storage, and are built with other storage areas (low-temperature storage, shady storage, etc.).If you want to build a small-scale quick-freezing warehouse, you can choose a combined cold storage, which is the assembly type said in the industry. Such an assembly cold storage saves costs, saves construction time, and has complete functions.

Difference between ammonia and Freon in Refrigeration system

1.One-time investmentIn general, large and medium ammonia refrigeration systems have slightly more investment than fluorine refrigeration systems of the same scale. The fluorine refrigeration system has a high degree of automation and less investment. Ammonia machine system is large, auxiliary machine is many, high pressure vessel is many, pipeline is complex, valve is many, each component is bigger and bulky. The fluorine machine system adopts intensive design, the whole unit leaves the factory, the unit occupies small area, the structure is simple, the use is convenient.2.Running cost The refrigerant of ammonia refrigeration system is cheap, the refrigerant unit refrigerating capacity is large, the electricity consumption is less, and the operation cost is low. Fluorine refrigeration system has higher working fluid price, smaller unit refrigerating capacity, higher electricity consumption and higher operating cost.1. Environmental characteristics. Ammonia, the refrigerant of ammonia refrigeration system, is a natural working medium with ozone depletion coefficient and no pollution to the environment. Because of the characteristics of destroying ozone layer, the ozone depletion coefficient (ODP) and the global warming coefficient (GWP) of CFCS are smaller, which can destroy the environment to a certain extent.4. Energy saving characteristicsThe ammonia refrigeration system has a larger COP coefficient and a better energy saving effect. The COP coefficient of the fluoro refrigeration system is small and the energy saving effect is poor.5, SecurityWhen the volume concentration of ammonia in the air reaches 5 ~ 0.6%, the person can be poisoned by staying in it for half an hour, and the concentration can be ignited when the concentration reaches 11 ~ 14. When the concentration reaches 16 ~ 25%, it will cause an explosion. No flammable explosive toxic refrigerant can be used. Freon is colorless, odorless, non-combustible, non-explosive, stable in chemical properties, and suitable for high, medium and low temperature refrigerators. The lowest evaporation temperature is -80 ℃.6.Liquid supply and gas return pipelineAmmonia system is connected with evaporator by down-inputting and outputting mode, and fluorine system is connected with evaporator by up-in and down-exit mode to facilitate oil recovery. The horizontal suction pipe of ammonia system should be sloping towards the circulating drum or the gas-liquid separator, and the horizontal suction pipe of the fluorine system should be sloping towards the compressor.7. Liquid supply modeAmmonia system and fluorine system can supply liquid directly, liquid pump and gravity liquid, and supply liquid to evaporator.8.Applied rangeAmmonia system and fluorine system are medium temperature refrigerants with moderate pressure and temperature. They can be used in refrigeration, air conditioning, industrial refrigeration, beer industry and pharmaceutical industry. Fluorine system is safer for direct evaporative air conditioning system. Ammonia systems can be used in air conditioning by indirect cooling 9.Automation control degreeThe fluorine system automation degree is high, generally does not need the manual operation, may save the labor cost. Most ammonia systems are operated manually, and the degree of automation is low, but the operation stability is good.10.Noise, vibration comparisonAmmonia machine volume is relatively large, noise and vibration are very large, a greater impact on the environment. Low noise and vibration of fluorine machine system.11. Applied rangeAmmonia systems are generally suitable for large and medium refrigerating, industrial refrigeration, ice making, artificial ice rink and indirect central air conditioning. Fluorine systems are generally suitable for refrigerators, display cabinets, domestic air conditioners, commercial air conditioners, small and medium cold storage and refrigeration, factory low temperature air conditioning, edible ice, and small industrial refrigeration.12. Equipment, pipes and valves for refrigeration systemsAmmonia system pipes are made of seamless steel tubes, steel containers and fittings, aluminum alloy pistons, seamless steel pipe evaporators or aluminum alloy evaporators; valves and fittings are specially designed for ammonia. Compressors are mostly piston type and screw type. The fluorine system pipe adopts copper pipe and seamless steel pipe, steel equipment, copper tube evaporator or aluminum alloy pipe evaporator, valves and fittings adopt fluorine special products. Compressor has digital scroll type, screw type, piston type, etc.13. Ammonia corrodes equipment and pipes when the ammonia system contains moisture. When fluorine system contains water, fluorine will also corrode equipment and pipeline, and form ice plug easily. Therefore, fluorine system should be equipped with dry filter.14. Find the leakAmmonia has irritating odor, ammonia system leak can be detected by using phenolphthalein test paper to turn ammonia red and litmus paper to ammonia to turn blue to find out that fluorine is colorless and tasteless, fluorine system leak can be detected by soapy water smear method and electronic leak detector method.15.The selection decision of ammonia refrigeration system and fluorine refrigeration system.
