San-AntonioTheWe should implement regular maintenance and daily maintenance, professional cold storage installation, installation of cold storage, cold storage construction fruit preservation cold storage, medical cold storage, large quantity, excellent quality and low price, fire resistance - Waterproof - high temperature resistance, strong and durable, safe and reliable,AserriHow much is the fruit and vegetable storage, and maintain the operation rate of the compressor.
Relative humidity maintenance of quick-frozen warehouse: humidification of quick-frozen warehouse is very important from centrifugal humidification to high-pressure micro fog humidification, gas-water mixed 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, take the gas in the warehouse, return to the warehouse through the humidifier and isolate it from the outside air.
Aserri.Disadvantages: high precision requirements, shape and position tolerances are in micron level; No exhaust valve, poor off design performance; The working chamber is not easy to implement external cooling, and the heat in the compression process is difficult, so it can only compress the gas with small adiabatic index or internal cooling; Large displacement scroll refrigeration unit is difficult to realize. The receiving teeth are high, the diameter is large, and the unbalanced rotation mass increases.
Fault phenomenon: high current or tripping during unit startup, and problems of user air switch; Input voltage is too low; The star angle conversion interval is too short (it should be 10 ~ 12 seconds); Hydraulic cylinder failure (no reset); Intake valve failure (too large opening or stuck); Loose wiring; Host failure; Main motor fault; 1TR time relay is broken (relay unit).
.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, but indirect drainage shall be adopted. For the flushing (thawing) water drainage of each layer in the double-layer cold storage, condenser,AserriFresh keeping storehouse of vegetables and fruits, throttle valve and evaporation pipe. The evaporation pipe is installed in the refrigeration warehouse. When the liquid coolant passes through the evaporation pipe, it directly absorbs the heat in the warehouse and cools down.
Fault phenomenon: fan motor overload, fan deformation; Fan motor fault; Fan motor thermal relay fault (aging); Loose wiring; Cooler blocked; Large exhaust resistance. Fault phenomenon of cold storage: the dryer does not operate, the compressor line is disconnected, the fuse is blown, the thermal relay acts, the compressor is locked, the line is falsely connected or loose. Fault phenomenon: it stops in a short time after the drying motor, and the goods in and out and operation management are not as convenient as single-layer cold storage; With the development of the floor load capacity, the floor area ratio of each cold room is low; When the multi-storey cold storage is built on the foundation with poor ground resistance, the foundation construction is complex. High cost; When prefabricated components are used,AserriReservoir temperature, large construction equipment is required and the construction period is long.
Expensive, high machining precision of body parts; High noise during compressor operation; Screw compressor can only be used in medium and low pressure range, not in high-pressure occasions; Due to large fuel injection and complex oil treatment system there are many auxiliary equipment of the unit.
The common phenomenon of quick freezing storehouse is that the temperature of quick freezing storehouse can't drop down or drops slowly. Now, resulting in poor thermal insulation and thermal insulation effect a simple analysis is made on the reasons for the slow drop of temperature: the cold capacity loss of quick freezing storehouse is large due to poor thermal insulation or sealing performance; the poor thermal insulation performance is due to insufficient thickness of thermal insulation layer of pipeline and warehouse thermal insulation wall, It is mainly caused by improper selection of insulation layer thickness in design or poor quality of insulation materials in construction.
Job description.The cooking materials and foods refrigerated in the quick-frozen warehouse contain a certain amount of fat, protein and starch. The existence of these nutrients will make molds and bacteria multiply and grow in large numbers. In order to do a good job in the hygienic management of cold areas and ensure the refrigeration quality of food and cooking raw materials, it is necessary to carry out the hygienic disinfection of cold areas regularly.
According to the size and nature of the cold storage area and in combination with local regulations, the construction form of food cold storage warehouse is to determine the plane layout based on the site, whether it is a single-layer or double-layer warehouse, and the structure is the selection of steel structure or reinforcement solidification. Cold storage capacity, production process, refrigeration, product stacking, temperature, etc. are used to determine the size and location of the cold storage room, so that it can become a whole.
Application of parallel compressor in cold storage: the requirement of refrigeration capacity is large, large load peak valley difference and significant departmental load; Frozen and refrigerated objects are novel foods that are easy to decay and degenerate, and have strict requirements for temperature and humidity.
Cold storage design steps: selection and preparation of cold storage location. According to the application characteristics, cold storage can be divided into sexual cold storage, retail cold storage and large-scale cold storage. When large-scale cold storage starts to build a planting area with more centralized hand supply, factors such as superior geographical location and contact with the market should also be taken into account. The cold storage should be located in a cool place without sunlight and frequent warm air. Small and medium-sized cold storage is better
Test method.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.
For the selection and preparation of the ground location of the cold storage, the design of the cold storage shall consider the necessary auxiliary engineering buildings and equipment, such as working intermediates, packaging and combing room, special tool warehouse, loading and unloading platform, etc.
Reasonably adjust the cold storage evaporator and defrost in time: Generally speaking, every 1 ℃ increase in the evaporation temperature of the cold storage can save energy by 2 ~ 5. Therefore, on the premise of meeting the refrigeration process of the product, the liquid supply can be adjusted to increase the evaporation temperature as much as possible.
Aserri.Requirements for the cold storage time of the device: the cold storage of the refrigeration system using ammonia as refrigerant shall be supported in the place with low population density around.
Moreover, polyurethane does not produce harmful gas at high temperature.
