Cold Store (English: Cold Store) is a kind of refrigeration equipment. Cold storage refers to the use of artificial means to create a different environment with outdoor temperature or humidity, but also for food, liquid, chemical, medicine, vaccines, scientific experiments and other items of constant temperature and humidity storage equipment. Cold storage is usually located near the port of shipment or the place of origin. Cold storage and refrigerator compared, refrigeration area is larger, and has the same refrigeration principle.
General cold storage refrigeration by refrigeration machine, the use of gasification temperature is very low liquid (ammonia or freon) as coolant, so that it evaporates under the condition of low pressure and mechanical control, absorb the heat in the storage, so as to achieve the purpose of cooling.
The most commonly used is the compression refrigeration machine, which is mainly composed of compressor, condenser, throttle valve and evaporation tube. It can be divided into direct cooling and indirect cooling according to the way of evaporation tube device. Direct cooling The evaporation tube is installed in the refrigerated warehouse, liquid coolant through the evaporation tube, directly absorb the heat in the warehouse and cool down.
Indirect cooling means that the air in the warehouse is pumped into the air cooling device by the blower, and the air is absorbed by the evaporation tube hovering in the cooling device, and then sent into the warehouse to cool down. The advantages of air cooling are rapid cooling, uniform temperature in the storage, and can take out harmful gases such as carbon dioxide generated in the storage process.
Food cold storage is used for food freezing and refrigeration buildings, it is through the method of artificial refrigeration, so that the warehouse to maintain a certain low temperature. In order to reduce the heat into the outside world, the cold storage of floor, wall and roof laying a certain thickness of moistureproof gas insulation and heat insulation layer, in the food cold storage engineering management, should according to the characteristics of the food cold storage, implement scientific management, to ensure the safety in production, prolong the service life, reduce production cost, save maintenance costs, enhance economic efficiency of enterprises.
Food cold storage can be widely used in food factory, dairy factory, pharmaceutical factory, chemical plant, fruit and vegetable warehouse, poultry egg warehouse, hotel, hotel, supermarket, hospital, blood station, army, laboratory and so on. Food cold storage is mainly used for constant temperature storage of food, dairy products, meat, aquatic products, poultry, fruits and vegetables, cold drinks, flowers, green plants, tea, drugs, chemical raw materials, electronic instruments and so on.
General cold storage engineering by refrigeration machine refrigeration, the use of gasification temperature is very low liquid as coolant, mainly composed of compressor, condenser and evaporation tube.
Drug cold storage temperature is generally +2℃ ~ +8℃, drug cold storage medicine and medical equipment cool cold storage is mainly cold storage in normal temperature conditions can not maintain quality of all kinds of medical products, cold storage in low temperature can make drugs do not deteriorate failure, prolong the shelf life of drugs, to meet the technical requirements of the Bureau of Medical supervision.
The drug cold storage has many advantages such as fast preservation and refrigeration, complete functions, energy saving and so on, and adopts the most advanced imported grain wheel refrigeration unit with low noise, which improves the refrigeration efficiency and reduces the energy consumption of the cold storage.
The temperature of the pharmaceutical warehouse is required to be from 2 ℃ to 8℃ for the storage of drugs. The refrigeration control system adopts automatic microcomputer electrical control technology, without duty. It mainly stores drugs and medical instruments, and can monitor and record the temperature and humidity of the storage area.
Refrigeration control system adopts automatic microcomputer electrical control technology, intelligent temperature control, the temperature in the storehouse within the range of +2℃ ~ +8℃ free setting, automatic temperature constant temperature, automatic switch machine, no manual operation, digital temperature display, to ensure the safe storage of drugs in the storehouse.
The library board of the pharmaceutical warehouse is made of rigid polyurethane color steel library board, which is only perfused by high pressure foaming process. The double-sided color steel insulation board adopts advanced eccentric hook and groove hook to achieve a close combination between the library board and the library board. The reliable sealing ability reduces the leakage of air conditioning to the greatest extent and increases the heat insulation effect. Scientific design, T plate, wall plate, corner plate combination cold storage can be assembled in any space, simple and practical, energy saving and environmental protection.
Hospitals with the widely application of ingredient blood, in the process of concentration of red blood cells separation, will produce a lot of fresh frozen plasma (FFP), than to promote growth, the number multiplied ingredients before blood frozen preservation became a huge problem, geared to increase the number of freezer alone, is bound to bring crowded space, paying too much, counting the inventory problems and preventing anything-from malpractices, Aiming at this problem, we carried out extensive investigation and research, and introduced the idea of mobile cold storage into plasma cryopreservation
Vaccine cold storage is mainly used to refrigerate and store all kinds of medical products that cannot be kept in good quality under normal temperature, so that the drugs will not deteriorate and become invalid under low temperature refrigeration, and the shelf life of the drugs will be extended. The storage temperature is generally -5℃~ +8℃.
The vaccine cold storage body is made of rigid polyurethane insulation sandwich board, which is perfused by high temperature foaming process. Double-sided color steel plate adopts advanced eccentric hook and groove hook library board eccentrically linked way to realize the close link between library board and library board. Excellent sealing ability can reduce the leakage of air conditioning to the greatest extent and enhance the heat insulation effect. T - plate, wall, corner plate combination cold storage can be assembled in any space. Scientific design, simple and practical, energy saving and environmental protection.
Vaccine cold storage refrigeration control system adopts automatic microcomputer electrical control system, intelligent computer temperature control, high precision temperature sensor, automatic temperature constant temperature, ground hole open and shut down, with automatic alarm, no manual operation, digital temperature display, optional temperature and humidity recorder, to ensure the storage safety of items in the storage.
Imported compressor is selected for the vaccine cold storage refrigeration unit, which has the characteristics of high energy efficiency ratio, strong refrigeration capacity, low noise, safety and reliability. The condensing radiator is equipped with efficient air-cooled condenser, and the external rotor low-noise motor is selected, which can effectively emit heat and maintain the high pressure at normal value under extreme high temperature environment, so that the refrigeration unit can play an efficient refrigeration effect, energy saving and environmental protection. The evaporator in cold storage adopts high efficiency ceiling cooling fan.
