Precautions for purchase and shipment when using the medical cold storage project, the speed must be strictly guaranteed during the purchase and shipment of products. If the temperature of the medical cold storage is about degrees, the opening time must be strictly within 25 minutes. If the temperature of the medical cold storage is left and right degrees, the opening time can not be too high, strictly within minutes.
There is a slight sag on the cold insulation board to prevent damage to the cold storage. When standing on the wall, some soft materials should be laid on the floor of the cold storage tank.
Tulzia cimpia turzii.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.
Different food processing technical processes for the construction of cold storage are combined with local urban planning. The construction of cold storage is the design requirements and construction of cold storage, which not only avoids the cross pollution between foods, but also ensures its transportation facilities: within the construction scope, saves land and reduces costs.
.The machine room of ammonia refrigeration system shall be equipped with exhaust assembly; The exhaust fan shall adopt anti motor. When the power supply is cut off due to unexpected refrigeration, it shall be able to ensure the reliable power supply of the exhaust fan. The overload protection of the exhaust fan should be applied to the signal alarm system without directly stopping the exhaust fan. The button box of the exhaust fan shall be concealed in the wall outside the ammonia compressor room.
Regular oil discharge, the evaporation temperature will decrease by 5 ℃ and the power consumption will increase by more than 10; When the scale on the water pipe wall in the condenser reaches 5mm in order to maintain the set temperature requirements, the condensation temperature will rise by 8 ℃ 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 0.196mpa, the power consumption will increase by about 1
If there is more air or refrigerant oil in the evaporator, the heat transfer effect will be reduced: once more refrigerant oil is attached to the inner surface of the evaporator heat transfer tube, the heat transfer coefficient will be reduced. Similarly, if there is more air in the heat transfer tube, the heat exchange area of the evaporator will be reduced the heat transfer efficiency will be significantly reduced, and the decline rate of warehouse temperature will be slowed down.
8. This shows the importance of regular oil discharge, descaling and air discharge in the refrigeration system of cold storage.
After startup, first listen to whether the sound of the compressor is normal, and see whether the condenser and cooling fan operate normally.
Points of multi-storey cold storage: small, which can save land; When the storage capacity is the same, the surface area of the outer enclosure structure is smaller than that of the single-layer cold storage, so that the cold consumption can be reduced, the dry consumption of food can be reduced, and the machinery and equipment cost and operation and management cost can be reduced accordingly. At the same time, due to the saving of thermal insulation materials, the civil construction cost per unit area is low and the investment cost is small; The multi-storey location can be reasonable, such as the cooling room can be used as the cold storage room, the attic on the top floor can be built into the ice making room, etc.
Where is good.The bubble density is 38 kg to 40 kg / m3 per cubic meter, and the steel plate thickness generally needs to be more than 0.4 mm to meet the standard. On the market, the main raw materials of special cold storage board for cold storage project are polyphenylene, polyethylene and polyphenylene grease. The density of thermal insulation material foamed by polyphenylene is thin, and the thermal insulation coefficient is not very high; After a certain ratio of polyethylene, it can foam cold storage insulation materials with appropriate density and good thermal insulation effect, and has high load-bearing capacity; Polyphenylene resin has strong water absorption, but poor heat insulation. Therefore, the polyurethane sandwich board with very good performance belongs to the polyurethane sandwich board. Although it is slightly higher,Tulzia cimpia turziiCharge for cold storage, the polyurethane board has very good thermal insulation performance and does not absorb moisture.
Frozen and refrigerated storage began to change to shelf and pallet storage to complete the goods according to & ldquo; First in first out & rdquo; It is conducive to improve the quality of commodity storage and reduce loss.
Stretch perlite: stretch perlite is a kind of granular material with porous layout. The gap in it blocks out the heat. Professional cold storage installation, cold storage construction, fruit fresh-keeping cold storage, medical cold storage, strict testing, quality assurance. Preferential activities are in progress. Welcome to consult. It has a good heat insulation effect. Then, the water vapor in the cold storage is easy to condense, and the water absorption of extensional perlite is particularly strong. If it absorbs a lot of water, its nature will be greatly reduced. Therefore, it is necessary to be careful to select extensional perlite as cold storage.
The closed cell structure and surface material of polyurethane rigid foam with good moisture-proof, waterproof and corrosion resistance make it have better air resistance and water vapor resistance, and it can be made into inlaid connection structure during forming, which is easy to assemble. It does not need additional insulating layer to prevent moisture and saves a lot of trouble in laying insulating layer.
How many?.When installing the polyurethane insulation board, the adhesion between the panel of the polyurethane insulation board and the thermal insulation material is short and often high.
The machine room shall be equipped with oxygen respirator gas mask, gas clothing, rubber gloves, wooden stopper, pipe clamp, acid beverage and other necessary protective and rescue articles, which shall be set in a convenient location, managed by a specially assigned person and used regularly. Relevant personnel shall skillfully master the use of oxygen respirator and personnel rescue.
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.
Tulzia cimpia turzii.The efficiency of the compressor is low, and the refrigerating capacity can not meet the load requirements of the warehouse: due to the long-term operation of the compressor, the cylinder sleeve, the long-term cold storage installation, installation,Tulzia cimpia turziiWhich is a good cold storage project installation, construction,Tulzia cimpia turziiFrozen storage, fruit preservation, medical cold storage and other brand products, the quality is guaranteed and the sealing performance will be reduced accordingly with the increase of the matching clearance, The gas transmission coefficient of the compressor will also be reduced, and the refrigeration capacity will be reduced. When the refrigerating capacity is less than the heat load of the warehouse, the temperature of the warehouse will drop slowly.
Install the library body. Generally, compact and solid, without hollow feeling, load-bearing, antifreeze, moisture-proof, etc.
Regular oil discharge, descaling and air discharge: when there is a 0.1mm thick oil film in the evaporator coil, in order to maintain the set temperature requirements, the evaporation temperature will decrease by 5 ℃ and the power consumption will increase by more than 10; When the scale on the water pipe wall in the condenser reaches 5mm, the condensation temperature will rise by 8 ℃ 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 0.196mpa the power consumption will increase by about 1
