With the development of the times, refrigeration devices are becoming more and more common. All aspects of life are inseparable from its use. Families will also be equipped with some simple refrigeration devices. For refrigeration devices such as cold storage, it is very important to select materials with good thermal insulation. Cold storage is a better material selection, and manufacturers need it in the production process of cold storage
On 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, controlled atmosphere storage of fruits can prolong the storage period by 2 & mdash; Three times or more. OK, what is the standard of quick freezing warehouse?
Progreso.The high temperature and high pressure of the compressor of the wholesale condenser of the fresh-keeping warehouse as the heat sink and heat exchanger needs to be dissipated and heat exchanged through the condenser, mainly to condense the refrigerant. The high-pressure temperature can reach Baidu, and the temperature will drop to 30 degrees after condensation.
Refrigeration system: refrigeration system is the core part of cold storage design. It is the key to determine the economy, environmental protection and performance of cold storage.
.There is a slight sag on the cold insulation board to prevent damage to the cold storage. When standing on the wall, some soft materials should be laid on the floor of the cold storage tank.
For water-cooled units, the turbidity of cooling water shall be frequently, the cooling water shall be replaced frequently, and whether the running, emitting, dripping leakage and other conditions of the water supply system exist.
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 ISO9002 quality operation, self inspection and inspection application shall be carried out to ensure that the factory pass rate is, and the product quality is relatively large. However it is not high-quality or good goods. This is the result of long-term cooperation.
If the refrigerator has been used for more than months, or the high / low voltage switch often fails, please arrange staff to clean the condenser. If the ultra-thin light box is repaired according to the above instructions for many times, and the refrigerator fault still sounds for a long time, please ask the maintenance personnel of the refrigerator to repair it.
In the cold storage project, the selection of cold storage is related to the overall operation of cold storage in the future. The selection of high-quality cold storage is conducive to the use and maintenance of cold storage. This requires us to inquire more about the warehouse board for cold storage engineering. Before the construction of cold storage project, we should first realize the temperature requirements of cold storage and the importance of cold storage to cold storage. Because the cold storage project has high environmental requirements such as temperature, attention should be paid to the performance and material of the cold storage board when selecting the cold storage board.
The cheapest.Insufficient refrigeration dose and capacity in the system: insufficient refrigerant circulation is the main reason
Install the electric control system. The electric control system of the cold storage mainly includes electric controller, electric door, lighting and other electrical equipment in the cold storage. The power supply of the cold storage is required to be stable phase line, and the power supply or backup power supply can be used as required. The circuit shall have reasonable discharge and corresponding protective measures.
The construction of small cold storage is widely used in life, such as food industry, manufacturing industry, 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.
When opening and drilling is required for the top warehouse plate or wall plate, the internal and external setting out and positioning shall be carried out according to the drawing design requirements, 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 300mm and 150mm outside.
Inspection items.The average service life of rigid polyurethane insulation structure with stable quality, long service life and high comprehensive cost performance can reach more than 30 years under normal use and maintenance conditions. Under the normal service conditions during the service life of the structure, it will not be affected by drying, or electrochemical corrosion, as well as the growth of insects, fungi or algae or rodents.
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.
Insufficient refrigeration dose and capacity in the system: insufficient refrigerant circulation is the main reason
Progreso.During operation, the water temperature will still drop, and the humidification amount will be reduced by 70% at 5 ℃.
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.
It is suitable for the freezing processing and storage of food, and manual refrigeration to keep the indoor temperature constant. The walls, the surface of the external wall of the cold storage is painted white or light color.
