The type of cold storage to be built in the type of cold storage should be determined according to the type of circulating goods. For example， while the cold storage with refrigeration + freezing will be built if there are many types of circulating goods and great difference in storage temperature. As for the size of the cold storage， it should be determined according to the type， quantity， frequency， cycle， whether to use shelf stacking and so on. For example， for fruits and vegetables packed in cartons， the storage capacity of -kg per cubic meter can be referred to， and the size of cold storage construction can be estimated in combination with the storage capacity rate of about .-..
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， it is not high-quality or good goods. This is the result of long-term cooperation.
DandmondAfter the user"s client app / PC logs in， the fresh-keeping warehouse can view the operation status and relevant parameters of the air conditioner in real time. In case of air return， air supply overrun and other faults， the alarm information can be received synchronously and the fault can be eliminated quickly.
Immediate cooling is to install the condenser of the cold storage in the box or building of the cooling equipment， use the volatilization of the refrigerant to immediately cool the air in the air， and use the cold air to cool the objects that need to be cooled. This kind of refrigeration is characterized by faster cooling speed， small heat conduction temperature difference and simple system software， the internal and external setting out and positioning shall be carried out according to the drawing design requirements， and the opening and drilling shall be carried out after review; The inlet hole， liquid inlet hole， return hole， water supply hole and drainage hole shall be opened with a hole opener. Construction treatment shall be carried out in time after opening and drilling and the orifice shall be closed with foaming material or sealant to prevent air leakage and cold running; The door， vent and delivery port shall be decorated with wrapped edges and fixed with pull rivets， with a spacing of mm and mm outside.
The wide，DandmondInstallation and maintenance of large cold storage， light and thin walls are made of rigid polyurethane foam at the same time as structural materials， 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.
Reasonably adjust the cold storage evaporator and defrost in time: Generally speaking， every ℃ increase in the evaporation temperature of the cold storage can save energy by ~ . Therefore， on the premise of meeting the refrigeration process of the product， the liquid supply can be adjusted to increase the evaporation temperature as much as possible.
Panel types of quick freezing warehouse: color plastic steel plate， salted steel plate， stainless steel plate， embossed aluminum， and there are corresponding strict requirements for the wall， ceiling， ventilation， disinfection and epidemic prevention of the warehouse. The refrigeration system adopts full-automatic microcomputer electrical technology and does not need to be on duty. It mainly stores western and Chinese grass materials and instruments， and can monitor and record the temperature and humidity in the storage area.
Where is itThe construction of small cold storage is widely used in life， such as food industry， manufacturing industry，DandmondWhich company is good for cold storage installation， etc. since cold storage is so widely used， do you know cold storage? Especially the construction process and steps of cold storage. Understanding the construction process and steps of cold storage is helpful for all links of cold storage maintenance.
Thermal insulation rigid polyurethane has low thermal conductivity and good thermal performance. When the density of rigid polyurethane is ~ kg / m， the thermal conductivity is only . ~ .w / (m.k)， which is the lowest among all thermal insulation materials at present.
Immediate cooling is to install the condenser of the cold storage in the box or building of the cooling equipment， use the volatilization of the refrigerant to immediately cool the air in the air， and use the cold air to cool the objects that need to be cooled. This kind of refrigeration is characterized by faster cooling speed small heat conduction temperature difference and simple system software， so it is widely used.
Cold storage has strong stability. Polyurethane foam technology makes it have superior bonding performance. The firm combination of polyurethane rigid foam and carrier layer is the basic premise to ensure the stability of external insulation layer. That is， under the unfavorable local temperature and humidity conditions， the characteristics of the cold storage still do not separate and fall off from the carrier layer and remain stable under normal conditions.
Quality recommendationOn the basis of cold storage and preservation， the quick-frozen warehouse increases the regulation of gas composition， 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，DandmondInstallation cost of fresh-keeping cold storage， controlled atmosphere storage of fruits can prolong the storage period by & mdash; Three times or more. OK， what is the standard of quick freezing warehouse?
In use the fresh-keeping warehouse must be maintained on time and scientifically. No matter how good the equipment is， without scientific use and maintenance， its service life and effect will be discounted. Therefore， so as to ensure its stable operation.
During the early operation of the refrigeration unit， carefully observe the oil return of the compressor and keep it clean. If it is found that the oil level is not clean enough or the oil level drops， replace it with new oil in time， so as to avoid bad compressor and reduce the service life of the compressor.
DandmondPolystyrene foam: polystyrene foam is a new type of synthetic thermal insulation material. It is a kind of plastic， light weight， strong heat insulation effect and excellent low temperature resistance. However， due to its cold shrinkage， it is not very convenient for installation.
Cold storage， lack of refrigerant， low pressure too low， excessive air intake， compressor jamming.
It is required to set up a special tally room (area)， and the temperature of the tally area is usually controlled at ~ + ℃.
