A large number of personnel are not allowed to select goods in the warehouse. Close the warehouse door in time. When the warehouse door is opened, so as to cool the refrigerant, 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.

South-Boston.The startup of the air-cooled refrigerator unit shall depend on whether the rotation direction of the fan is correct. If the forward rotation can be started for operation, the reverse rotation indicates that the power wiring is reversed, and the phase sequence must be replaced before startup.

Polyurethane foam foam dimensional stability: cold storage polyurethane foam in severe temperature changes or at a relatively low temperature will appear dimensional changes (as contraction), and these will inevitably affect the normal use of cold storage. In addition to regular simulation of performance testing, more emphasis is placed on the selection of high quality materials: special energy polyether compound use, so that the foam body mesh structure, greatly improving the foam low temperature resistance. At present 4110 polyether commonly used in spraying materials contains a large number of functional components, and a large number of linear structures formed after reaction are difficult to be stable at low temperature; The use of the energy crosslinking agent also greatly improved the dimensional stability of the foam. The selected polyether adopts catalysis in the production stage, and the reaction is complete, so that the polyether maintains a high reaction rate (that is, it can react completely with black material); Some manufacturers in order to achieve foam appearance does not produce deformation phenomenon and add a hole component to foam material, reduce the bubble closed hole rate, achieve the effect of stable size, but it has sacrificed the thermal insulation performance of polyurethane cold storage insulation material foam.

.Whether there is dirt on the condenser and poor heat dissipation will lead to too high condensation pressure of the refrigerator. In order to protect the compressor the machine stops running under the action of the pressure controller. When the heat dissipation is good, press the black reset button on the pressure controller, and the machine can automatically resume operation.

The refrigerator compressor unit generally adopts high-end units with guaranteed quality and strong operation stability. The evaporator adopts the imported joint venture refrigeration air-cooled evaporator, which can effectively meet the refrigeration capacity of the refrigerator and ensure the refrigeration effect of the refrigerator. The refrigerator lamp adopts the special LED energy-saving lamp for the refrigerator, which has the advantages of low temperature resistance, low energy consumption and long service time,South-BostonWhich is the fruit fresh-keeping cold storage good, It can effectively save the operation cost of cold storage.

The cold storage belongs to a kind of refrigeration equipment. Compared with the refrigerator, its refrigeration area is large, but they have the same refrigeration principle. So how to maintain the cold storage every day. Today I'll introduce how to do a good job in the daily management and maintenance after the installation of the cold storage.

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.

However not all controlled atmosphere reservoirs can choose to adjust with a large depth, coupled with the user's energy-saving effect of the hot air fan, so that the energy-saving effect of the hot air fan will be significantly improved.

During installation the plates shall be handled with care. Rough operation is strictly prohibited. Burrs shall be removed at the cutting opening to prevent scratching the plate surface and workers.

Project scope.How to maintain the refrigeration compressor in the cold storage in order to prolong its service life and reduce the occurrence of faults in the use process. The refrigeration compressor in the cold storage needs regular maintenance. Here we introduce the maintenance of the compressor in the cold storage.

The equipment configuration is reasonable and the service life of the quick freezing warehouse is long. The reasonable equipment configuration of the quick freezing warehouse can greatly prolong the service time of the quick freezing warehouse. Some compressors are easy to be damaged when they work at full load for a long time, so we try to use screw parallel units. The great advantage of this unit is that it can turn on all equipment, just like the shift at work, so that the compressor can work and rest in turn.

After the cold storage at the corner is installed, the next cold storage can be installed along the direction of the corner. Adopt the similar installation of Zhang cold storage to install the thermal insulation board of the storage. Professional cold storage installation, installation of cold storage, cold storage construction, fruit preservation cold storage, medical cold storage, advanced technology, strict testing, more affordable price and more preferential. Welcome to consult. Pay attention to its compactness and continuous uniformity.

In fact, there are some unique installation skills when installing the cold storage? The cold storage installed according to these skills is often short in both effect and quality, and the specific installation skills of the cold storage will also make some relatively detailed introduction for you in the following article. When installing the cold storage, you should install it from the corner first. Later, according to the height of the cold storage, make a hole in the middle of the insulation board behind the angle iron parts

Bidding.Fire retardant, flame retardant and high temperature resistant polyurethane is a kind of flame retardant self extinguishing material after adding flame retardant. Its softening point can reach more than 250 ℃, and it will decompose only at higher temperature. In addition, polyurethane forms carbon deposits on the surface of the foam, which helps to isolate the foam below. It can effectively prevent flame spread.

Vibration shall be prevented during the whole operation of the refrigeration unit. In addition to the abrasion of the lifting mechanical equipment, vibration will continue to cause loosening or cracking of the upper connecting pipe of the generator unit. If abnormal noise is found during the whole operation of the equipment, the quick-frozen warehouse increases the regulation of gas composition,South-BostonPreservation of fruits and vegetables in cold storage, inhibits the respiration of fruits and vegetables, delays their metabolic process, better maintains the freshness and commercial quality of fruits and vegetables, and prolongs the storage period and shelf life of fruits and vegetables. Generally, controlled atmosphere storage of fruits can prolong the storage period by 2 & mdash; Three times or more. OK, what is the standard of quick freezing warehouse?

South-Boston.The refrigeration equipment in the fresh-keeping environment of the quick-frozen warehouse mostly adopts the single-stage compression refrigeration system, with freon as the refrigerant. The evaporation mode in the warehouse is the cooling fan, which can be ceiling type. If the number of warehouses is small and the volume does not exceed 500 cubic meters, the refrigeration mode of the warehouse machine can be considered. If there are a large number of warehouses, the mode of multiple heads in parallel can be considered.

The bacterial action of acid disinfectants is mainly to coagulate the protein in the bacteria. Common disinfectants include lactic acid, bleach, formalin etc. Specifically, after the fish comes out of the freezer, clean the frost layer on the evaporating pipe group and keep the storehouse temperature below 50 degrees Celsius. Then, according to the volume of 50~100 grams per cubic meter volume of the frozen storeroom, the storeroom door is closed tightly with the sprayer, and the blower is started intermittently, so that the vinegar evaporates and flows in the storehouse, which makes the vinegar absorb a lot of fish smell.

Large space rate of quick-frozen warehouse: for quick-frozen warehouses of the same size, reasonable design schemes store more goods than unreasonable ones. For the fixed size quick freezing warehouse, how to design it to maximize its space rate is often an important problem considered by our designers. In the design scheme of Lukang medical quick-frozen warehouse, we reasonably designed to expand the original storage capacity of 300 boxes to 400 boxes, which increases the space a lot.
