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.
These are several very common cold storage materials. The use of these materials has greatly improved the thermal insulation and refrigeration performance of the cold storage， which makes peoples retained items more convenient and reliable. With the continuous development of material technology todays various cold storage materials emerge in endlessly， and the cold storage is different from each other. When purchasing， we should make reasonable comparison and select products suitable for our own use needs and economic conditions.
RoThe logistics cold storage project in the tally area belongs to the type of cold storage with frequent goods in and out and large quantity. Therefore，Modified atmosphere storage in order to keep the temperature fluctuation in the warehouse small，Cold storage design and installationYou can tell at a glance it is more necessary to store the temperature and time of goods entering and leaving the warehouse. Introduction to KFC refrigeration: logistics refrigerators with frequent incoming and outgoing goods and large throughput， especially low-temperature logistics refrigerators， usually set up a special tally area according to business needs， and the temperature of the tally area is generally ~ ℃. In addition， a transfer room will be set in the logistics cold storage to avoid the loss of refrigeration capacity caused by frequent opening and closing of the cold storage door，Cold storage installation - cold storage installation - cold storage construction - fruit preservation cold storage medicine cold storage - Anhui Fuyang Xinyuan Refrigeration Technology Engineering Co., Ltd or unqualified temperature and serious frosting.
aPolyurethane foam foam dimensional stability: cold storage polyurethane foam in severe temperature changes or at a relatively low temperature will appear dimensional changes (as contraction)， the size changes often reflect bubble cracking or falling off， 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，Modified atmosphere storage 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， 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 so that the polyether maintains a high reaction rate (that is， reduce the bubble closed hole rate，Cold storage design and installationYou can tell at a glance achieve the effect of stable size， but it has sacrificed the thermal insulation performance of polyurethane cold storage insulation material foam.
Cold storage doctorCareful use should be carried out many times
Air volume regulation is the key factor to save energy. If we can do this well， the fan can meet the flow or pressure requirements of production under the stable working conditions， and can save energy to the limit. In the process of implementing fan regulation，Modified atmosphere storage it is important to choose what regulation， which can directly affect the energy-saving effect of controlled atmosphere storage.
When the cold storage is used for the first time or shut down for a long time， it is strictly prohibited to stack goods in the warehouse. The warehouse must be slowly reduced to the required temperature. For the low-temperature warehouse， it needs to be cooled in stages to avoid sudden changes in the temperature difference inside and outside the warehouse， resulting in the warehouse body.
Technical assurance measures for the installation of cold storage: during production in the production workshop， the production shall be carried out in strict accordance with the operation rules specified in ISO quality operation， self inspection and inspection application shall be carried out to ensure that the factory pass rate is， and unqualified products are not allowed to leave the factory.
