The polyurethane insulation board shall be connected by plug-in notch connection, because it has higher strength when connecting in this way.Pay attention to the energy saving of the lighting system: the lighting of the cold storage should be considered comprehensively according to the area, height and warehouse temperature of the cold storage on the basis of safety, science and rationality, from the perspective of energy saving and environmental protection. The lighting in the cold storage is concentrated in the working area.the danube,The warehouse shall be reasonably divided and set with relevant signs to facilitate the storage, transportation and management of goods in the warehouse.The combined cold storage does not cool or the cooling effect is poor. Check whether the condenser of the refrigerator is dirty. Whether frost is too thick on the evaporator in the warehouse. Check whether the refrigerant is leaking (apply soapy water to the pipeline connection, and if bubbles are generated, it indicates that the refrigerant is leaking). And ask the combined cold storage engineering personnel to supplement the refrigerant and deal with the leakage. Check whether the sealing of the combined cold storage door is intact and eliminate it. Whether the refrigerator of the combined cold storage works. Whether the parameter setting of the computer controller of the cold storage is correct, and reassemble the cold storage door for installation. Check whether the cooler in the cold storage fails and replace it. Whether there is enough clearance for stacking articles in the warehouse and dredge them.Langerud,Commissioning cold storage. After all parts of the cold storage are installed and connected, the cold storage can be started for cold storage commissioning. According to the needs of customers adjust the value of the cold storage, the cold storage can reach the predetermined temperature, the cooling speed and the operation of the cold storage are normal, and the cold storage can be delivered for use. The cold storage installation unit shall also provide the cold storage user with training on cold storage use and management knowledge, as well as some after-sales training.Preparation, prepare the project planning of cold storage, and prepare the construction site and construction materials. All kinds of materials for cold storage construction are customized according to the needs of customers. Sort out the construction site that meets the requirements, transport all installation materials to the construction site, check the material quality and model, and start the installation of cold storage after confirmation.Cold storage design step: the selection of cold storage refrigeration system the selection of cold storage refrigeration system is mainly the use of cold storage refrigeration compressor and air conditioning evaporator. Generally, the price is relatively cost-effective; Small and medium-sized refrigerators are generally dominated by semi closed refrigeration compressors; Semi closed refrigeration compressor is adopted for large and medium-sized refrigerated warehouses. When adopting, ammonia refrigeration unit can also be considered. Because the output power of ammonia refrigeration unit is large and can be used for machine use, but the installation and management of refrigerated warehouses are cumbersome. When using the air-conditioning evaporator, the high-temperature cold storage uses the industrial cold fan as the air-conditioning evaporator. Its characteristic is that the temperature reduction speed is faster, but it is easy to lead to the water consumption of the cold collection; Medium and ultra-low temperature refrigerators are dominated by seamless evaporation pipe slots, which is characterized by very good temperature control effect and moderate cold storage.

As a coolant, make it evaporate under low pressure and mechanical conditions to absorb the heat in the storage so as to achieve the purpose of cooling.Clean the bearing and replace the oil in the centrifugal pump, and the vibration of the shaft.The evaporator surface is too thick or too much dust, and the heat transfer effect decreases: another important reason is that the heat transfer efficiency of evaporator is low, which is mainly caused by excessive frost or excessive dust on the evaporator surface.technological innovationPoints of multi-storey cold storage: small,the danubeInstallation of cold storage area, 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.There should be excellent drainage pipe standard around the warehouse, and maintain good natural ventilation. Maintaining dryness is very important for the cold storage. In addition there should be interlayer under the cold storage, before the construction of the cold storage, the phase electricity of the relative volume shall be built according to the output power of the refrigeration unit. If the cold storage is water-cooled and radiating, the tap water pipeline shall be paved and the FRP cooling tower shall be built.Pay attention to the energy saving of the lighting system: the lighting of the cold storage should be considered comprehensively according to the area, height and warehouse temperature of the cold storage on the basis of safety, 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.Excellent quality,the danubeInstallation and maintenance of cold storage,Installation of box and operating device: the design of box shall be reasonable, and the appearance quality shall meet the requirements of beauty and practicality. All buttons electrical switches, etc. shall be reliable, safe, long-term cold storage installation, cold storage installation, cold storage construction, fruit preservation cold storage, medical cold storage, old brand, price advantage and quality guarantee! Easy to identify and operate. The indicator light shall be simple and clear. The device and each switch shall be installed on the upper side outside the warehouse door, which is easy to operate, read data and not easy to be damaged, and shall be reliably fixed. The device box is installed on the door frame plate on the door opening side. The center line of the box overlaps the center line of the door frame plate. The bottom of the box is mm above the ground and is reliably fixed. The lighting lamp and door frame wire switch in the warehouse are installed directly below the device, and the height of the bottom edge of the switch box is about mm.Water defrosting: spray the defrosting water spray device on the surface of the evaporator to melt the double layer, and then through the drainage pipe. This scheme has high efficiency, simple operation procedure and small temperature fluctuation. From the perspective of energy, the cooling consumption per square meter of evaporation area can reach -kj. Water frost flushing is also easy to make fog in the warehouse, cause dripping water on the ceiling of the cold room, and reduce the service life.Energy saving and power saving: the design cost of quick freezing warehouse mentioned above is very low, but it has a great impact on the cost of quick freezing warehouse and later use cost. The electricity bill is often an important expenditure item in the later stage. The design scheme of the show can greatly reduce the power consumption of the quick freezing warehouse. The selection of the back sunny side of the quick freezing warehouse, the selection of the thickness of the thermal insulation board should be appropriate, the tightness of the quick freezing warehouse door, and the temperature difference between the adjacent cold storage rooms should not be too large are all issues that we need to consider. There are also some tips,Because polyurethane sheet has excellent thermal insulation performance, it can reduce the thickness of building envelope and increase indoor use area under the same thermal insulation requirements.When installing polyurethane insulation board, ensure that its surface is smooth and flat without scratch and warpage.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,the danubeCold storage installation company, 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.
