Vientiane CityInstallation of vegetable fresh-keeping cold storageWhat tests should be carried out before use

Connect the refrigeration system. Wires and copper pipes shall be used to connect the refrigeration unit, electric control system and other components of the cold storage. The connecting pipes shall be closely connected, and corresponding thermal insulation and protection measures shall be taken.The selection of equipment for the construction of equipment cold storage is closely related to the size type and budget of the cold storage.Vientiane City,Measure the winding resistance of the compressor and the insulation of the motor.Establish a perfect computer network, make the distribution of refrigeration supply chain scientific, and achieve the traceability of food safety. In the European Union, the United States and Japan, all members of the food supply chain have the legal responsibility to implement traceability.Opava,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, pay attention to whether the air curtain is opened or the door curtain is placed properly. Turn off the lights when leaving the warehouse.The service life of polyurethane cold storage insulation material foam is: besides the basic performance of the initial stage of polyurethane foam, the deterioration of foam performance is also a very important index. When the white material is prepared, the surface of some polyester materials can make the foam have better toughness and impact resistance, but it will become brittle after use for a long time in the cold storage, and will no longer resist impact and collision. In addition, the poor hydrolysis resistance of some polyester foam will also affect the service life of the foam. It adopts polyether structure, which is slightly brittle at the initial stage, but generally disappears after a few days, and then maintains the stable performance of cold storage insulation materials for a long time.The water tank is designed to be separated from the machine body and is double-layer. It will not drip due to condensation caused by internal and external temperature difference. It can be interlocked with the refrigeration system, that is, it will not be humidified during refrigeration to prevent serious frosting of the fan.

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, apply refrigerant oil to strengthen the tightness. Clean after fastening. The packing of each cut-off door shall be locked.The factors affecting the installation cost of cold storage are as follows: cold storage construction: the site selection shall comply with laws and regulations and meet the relevant requirements for food hygiene and. And pay attention to protecting the environment and ecological balance. In addition it is not high-quality or good goods. This is the result of long-term cooperation.Before fastening all sodium nuts and lock nuts of the refrigeration system,Vientiane CityInstallation of cold storage equipment manufacturer, it shall be conducive to production, polyurethane is a kind of flame retardant and self extinguishing material. If it is burned by fire, it can be carbonized, unlike flow burning and flashover like extruded board, which can effectively prevent fire spread. In particular, it can be closed as a whole after fire prevention treatment to form non combustible products.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 such as the use of air curtain machine on the quick freezing warehouse door. We remind users to use parallel units in quick freezing warehouse as far as possible and start them reasonably.Cold storage is mainly used for frozen processing and storage of food

The wide, light and thin walls are made of rigid polyurethane foam at the same time as structural materials,Vientiane CityWhich one installs cold storage, making the whole structure have the advantages of light weight, large span and high load. The thinner polyurethane sandwich plate can meet the relevant provisions on building energy consumption limit, which allows the use of thinner plates during construction and saves building space.High value,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 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 valve shall be installed as close as possible to the cooling fan. The solenoid valve shall be installed horizontally, the valve body shall be vertical, and pay attention to the liquid outlet direction.Points of multi-storey cold storage: small, 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,Judge the operating sound of the compressor, and carefully listen to the operating sound of water pump, cooling tower, compressor,Vientiane CityFast cold storage, 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.Proper protective measures shall be taken during transportation to prevent plate from being strangled and scratched.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.
