Moreover, polyurethane does not produce harmful gas at high temperature.
The equipment is built according to the application requirements of low-temperature distribution. It is reflected in the following 6 points: a low-temperature hall, a closed platform, an electric sliding refrigerated door an anti-collision flexible seal, and a platform height conditioning equipment (lifting channel) are built to complete & ldquo; Door to door & rdquo; Type loading and unloading operation has become a symbol of modern cold storage.
Saint-Louis.The shelves in the warehouse shall have sufficient strength and rigidity.
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.
.Requirements for the cold storage time of the device: the cold storage of the refrigeration system using ammonia as refrigerant shall be supported in the place with low population density around.
The quantity is large, and a special tally room (area) is set according to the needs of production and operation. The temperature of the tally area is usually controlled at 0 ~ + 7 ℃.
For the flushing (thawing) drainage pipe in the cold room with different temperature, installation of cold storage, cold storage construction, fruit preservation cold storage, medical cold storage and transaction safety are guaranteed. Through internal concave convex groove connection, loading, unloading and handling are convenient. The installation period is short. Small and medium-sized cold storage can be delivered in 2-5 days, separated or increased or decreased according to the needs of users.
According to the needs and uses of different engineering scenarios, the design and construction of cold storage are different. When designing cold storage according to actual needs, nine aspects generally need to be considered.
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.
Quality inspection report.With the increasing use of cold storage, cold storage board, as an important structure of cold storage, is also increasing. Because cold storage is different from other ordinary cold storage, it is important to the installation environment and temperature. Therefore some small problems may be ignored during installation. According to the following understanding.
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 shall be conducive to production, construction and dry ceremony.
The installation of cold storage board is a link of the cold storage installation project. High price cold storage installation of various specifications, cold storage installation, cold storage construction, fruit preservation cold storage, medical cold storage. Waste merchants, industry, enterprises and power departments are welcome to visit and negotiate! The cold storage body and storage plate include: floor, vertical plate and ceiling plate. The installation of storage plates in different directions and precautions are as follows: enter the construction site, verify the construction situation according to the construction drawings, determine the equipment installation position, and then refer to the following specifications.
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 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
Job description.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.
The suction pipeline of the compressor and the return pipeline of the cooling fan shall not be smaller than the size indicated in the sample to reduce the internal resistance of the evaporation pipeline.
Vent valve or water seal well shall be set at the outlet of flushing (thawing) drainage pipeline. Cold proof measures shall be taken for exhaust valves and water sealed wells in severe cold areas.
Saint-Louis.Before the acceptance and delivery of the project, the board surface shall be wiped clean. If there is any scratch, it shall be treated. There shall be no obvious scratch on the board surface.
Features of quick freezing warehouse: the quick freezing technology is advanced, the frost free quick freezing method is adopted, the famous brand compressor and refrigeration accessories are configured, and the automatic frost is adopted. The method can only be used by microcomputer. The refrigeration system adopts green refrigerant, which belongs to the international advanced refrigeration technology in the 21st century.
The temperature and humidity in the warehouse shall be kept uniform without movement; Try to finish the food in the warehouse at one time.
