The refrigerant charge is insufficient. At this time, just add enough refrigerant.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.Dorn bean,If the refrigerator has been used for more than months, or the high / low voltage switch often fails, or the refrigeration capacity is reduced, 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.Regular oil discharge, descaling and air discharge: when there is a .mm thick oil film in the evaporator coil, in order to maintain the set temperature requirements, the evaporation temperature will decrease by ℃ and the power consumption will increase by more than ; When the scale on the water pipe wall in the condenser reaches mm, the condensation temperature will rise by ℃ compared with the original temperature, and the power consumption will increase. When the refrigeration system is mixed with non condensable gas and its partial pressure reaches .mpa the power consumption will increase by about . It can be seen that it is coldRanchuelo,The equipment configuration is reasonable and the service life of the quick freezing warehouse is long. The reasonable equipment configuration of the quick freezing warehouse can greatly prolong the service time of the quick freezing warehouse. Some compressors are easy to be damaged when they work at full load for a long time, so we try to use screw parallel units. The great advantage of this unit is that it can turn on all equipment, just like the shift at work, so that the compressor can work and rest in turn. - precautions for vertical plate of cold storage: vertical plate displayCold storage is mainly used for frozen processing and storage of food

Step of cold storage design: selection and laying of cold storage thermal insulation materials. The use of cold storage thermal insulation materials must be adjusted to the time, which not only has excellent fire resistance, but also has high cost performance. There are several types of cold storage insulation materials. One is the plate produced and processed into a fixed shape and specification, with fixed length, total width and thickness. The cold storage plate with relative specification and model can be selected according to the installation of the warehouse body. The high and medium temperature cold storage generally adopts cm thick cold storage plate, cm or cm thick cold storage board is generally used for ultra-low temperature cold storage and freeze-cleaning cold storage; Another kind of cold storage can be sprayed with polyurethane spray paint and polyurethane foam, it is both waterproof and thermal insulation. Thermal insulation materials include polyurethane, polystyrene grease, etc. Polyurethane is non hygroscopic and has good fire resistance, but the cost is high; Polystyrene resin has strong water absorption capacity and weak fire resistance,Dorn beanPrice of cold storage,Dorn beanInstallation of refrigeration equipment and cold storage, but the cost is low.The gap between the cooling fan and the storage plate shall be greater than the thickness of the cooling fan.The selection of equipment for the construction of equipment cold storage is closely related to the size, type and budget of the cold storage.Free consultation,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.It is required to set up a special tally room (area), and the temperature of the tally area is usually controlled at ~ + ℃.Thermal insulation rigid polyurethane has low thermal conductivity and good thermal performance. When the density of rigid polyurethane is ~ kg / m, construction of cold storage which is the lowest among all thermal insulation materials at present.

Installation of cold storage, fruit preservation cold storage and medical cold storage have stable, reliable and maintenance free performance. The technical level has reached the domestic level and the advanced level of similar international products. If there is a large amount of ice and water, it must be cleaned in time and it must not be knocked during cleaning, so as not to damage the ground and affect the service life of the cold storage.How much does it cost?,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.System blowdown: it is easy to use the standby air compressor. When the air compressor cannot solve the problem, it can be replaced by ammonia compressor, but the exhaust temperature during use shall not exceed ℃, otherwise the oil viscosity will be reduced beyond the flash point and carbon will be formed, and corresponding protection measures shall be taken for the installed equipment.Dorn bean,During the use of the goods yard medical cold storage project, the stored goods must be in strict accordance with the relevant regulations. The goods should have a certain distance from the ground and wall of the cold storage. When stacking the distance between the goods and the goods must be cm. At the same time, the distance between the goods and the cold fan should also be cm. No goods can be stored within this range,Dorn beanPharmaceutical company cold storage, This is also an important content in the use of medical cold storage engineering.Polyurethane with good fire resistance and flame retardancy is a kind of refractory and self extinguishing material after adding flame retardant. In case of fire, it can be carbonized, unlike flow burning and flashover like extruded board, which can effectively prevent fire spread. In particular, it can be sealed as a whole after systematic fire prevention treatment to form non combustible products.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.
