The use of large-scale cold storage is naturally very strict in installation and material selection. Therefore, in the face of the above possible situations, we can strictly screen the insulation board materials of cold storage, which can effectively alleviate or solve the above problems. However, at present, there are many fields using cold storage insulation board so the details of the use environment should be considered for the wood making of many such products in the market.
Application of parallel compressor in cold storage: the requirement of refrigeration capacity is large, and 5 to 50 refrigeration compressors under 20 Malige need to be used on weekdays; Long term operation, 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.
Sagna.When the valve is opened too large or too small, the fresh-keeping warehouse will lead to too large or too small refrigerant flow, poor valve operation, reduced refrigeration efficiency and even equipment damage.
The installation of top warehouse plate should be carried out alternately with the installation of wall plate, and the wall plate should leave a gap for withdrawing construction equipment; During the installation of the top warehouse plate, the end steel sheet at the overlap with the wall plate shall be disconnected for 50mm to prevent the cold bridge from running cold; Two layers of foaming materials shall be evenly and continuously punched on the joint surface between each top warehouse plate. Rivets shall be pulled and fixed at the internal and external lap joints of the steel plate, and the rivet spacing shall be 300mm; According to the design drawings, if there are supporting beams, columns and supporting steel frames in the warehouse, the setting out and positioning shall be carried out and accurate and clear marks shall be made according to the requirements of the design drawings; Weld or install the support beam, column, etc., and the welded junction shall be moisture-proof and treated according to the drawing requirements.
.Judge the operating sound of the compressor, and carefully listen to the operating sound of water pump, cooling tower, compressor, fan and other equipment. In case of abnormal sound, timely warranty is required, so as to avoid greater damage to the compressor due to untimely warranty.
Initial operation unit of cold storage equipment: regularly observe the oil level and oil return of the compressor and the cleanliness of the oil. If the oil is dirty or the oil level drops, it shall be solved in time to avoid adverse effects.
Polyurethane spraying is widely used in large and medium-sized refrigerators. Different well-known brands are produced at different prices, and the product quality is relatively large. However it is not high-quality or good goods. This is the result of long-term cooperation.
The combined cold storage door starts frequently or does not start for a long time, or does not stop for a long time, or stops before the storage temperature reaches.
If the warehouse is relatively small and you want to transform a miniature fruit fresh-keeping warehouse, you should ensure that the height in the warehouse is at least 8 meters, because the top of the cold storage and the top of the warehouse should reserve a height of at least 30 cm.
During the use of cold storage, attention shall be paid to the collision and scratch of the storage body to avoid the depression and corrosion of the storage plate which will seriously reduce the local thermal insulation performance of the storage body.
investment.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 high-voltage switch 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 environment
During the use of cold storage,SagnaInstallation of cold storage, attention shall be paid to the collision and scratch of the storage body to avoid the depression and corrosion of the storage plate, under the unfavorable local temperature and humidity conditions, it can bear various internal and external combined loads such as wind force, self weight and normal collision, and the insulation layer still does not separate and fall off from the carrier layer and remains stable in the state.
Simple refrigeration is based on the volatilization of refrigerant in the condenser of the cold storage, so as to cool the refrigerant, and then input the refrigerant into the box or building of the refrigeration equipment to cool the air according to the heat exchanger. This kind of refrigeration has slow cooling speed, large total heat conduction temperature difference and complex system software, so it can only be used in less places, such as brine ice making and cold storage with constant temperature requirements.
Where can I find it?.There are two kinds of refrigeration in the cold storage group: immediate refrigeration and simple refrigeration.
Frequently check and acknowledge whether the voltage of the power supply meets the requirements and the voltage should be 380V & plusmn; 10% (phase line). When the fresh-keeping warehouse equipment is not used for a long time, and it shall be ensured that the fresh-keeping warehouse equipment is not affected by moisture, dust and other substances. The condenser on the refrigeration unit is simply contaminated, and the fresh-keeping warehouse shall be cleaned regularly according to the actual situation. To adhere to outstanding heat transfer.
The foaming technology of polyurethane with strong stability makes it have superior bonding performance. The firm combination of polyurethane rigid foam and carrier layer is the basic premise to ensure the stability of external insulation layer. That is, under the unfavorable local temperature and humidity conditions, it can bear various internal and external combined loads such as wind force, self weight and normal collision, medium and large cold storage is different, which is closely related to the purpose, storage products and size of cold storage. Kuhua refrigeration reminds: ground insulation must be done, otherwise the temperature in the cold storage often fluctuates frequently due to poor insulation performance, which affects the quality of stored goods. So,SagnaHow much does it cost to install a cold storage, what is the difference between the ground insulation of small, medium and large cold storage? How to do better?
Another reason is that there are many refrigerants in the system. In this case, find the leakage point first, focus on the connection of each pipeline and valve, repair the found part, and then fill in sufficient refrigerant.
The exhaust temperature of the compressor equipment is often. When the season changes and the temperature difference changes greatly, pay attention to it. If the machine is abnormal, it needs to be checked in time.
