Equipped with perfect storage temperature active detection, recording and active control equipment.During the installation of cold storage board in cold storage, its installation quality will directly affect the temperature of cold storage. As an important structure used in the cold storage, the cold storage board should pay attention to the details of its installation, find out the problems that are easy to be ignored, and avoid the wrong installation,OrleansWhich cold storage is installed, which will affect the use of the cold storage or the whole installation process, so as to waste resources and increase the cost.

The equipment that needs to be installed in the warehouse and put into the warehouse shall be installed in place or placed in an appropriate position in the warehouse; The wall warehouse board shall be installed from the corner of the warehouse body, and the professional cold warehouse shall be installed. The cold warehouse shall be installed. The cold warehouse shall be constructed. The fruit fresh-keeping cold warehouse and medical cold warehouse shall have high pressure rating, fire and high temperature resistance, strong overload capacity, corrosion resistance, radiation protection and long service life. The corner shall be temporarily fixed with . color plate angle steel; When installing each wall panel evenly apply two layers of foaming material on the joint surface of male and female groove, and apply one layer of foaming material when installing polystyrene wall panel. The blanking shall be uniform and continuous; After the wallboard is installed in place, pull rivets at the lap joint of the internal and external steel plates of the two wallboards for connection and fixation, and the rivet spacing in the warehouse should be mm; When connecting the library plate in the form of eccentric hook connection, the eccentric hook shall be loosened once before installation to ensure reliable locking during installation.Vacuum test: after the system pressure test is qualified, the system can be vacuum leak tested. The purpose is to improve the air tightness under vacuum conditions and prepare conditions for ammonia filling of the system. - precautions for floor installation of cold storage: the floor shall be installed flat, the uneven part shall be leveled with materials, and the locking hook between the plates shall be locked to ensure that the warehouse surface is flat without hollow feeling. (note that if this drainage system is installed outdoors in the north, the drainage pipe shall be insulated).Sales Department,The evaporator surface is too thick or too much dust, and the heat transfer effect decreases: another important reason is that the heat transfer efficiency of evaporator is low, which is mainly caused by excessive frost or excessive dust on the evaporator surface.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.Airtight construction of quick freezing storehouse: the modified atmosphere fresh-keeping storehouse is developed on the basis of the traditional high-temperature fresh-keeping storehouse, cold storage installation long-term cold storage installation, cold storage construction, fruit fresh-keeping cold storage, complete products, excellent quality and favorable price. There are also & ldquo; Air conditioning & rdquo; Function; However the quick freezing storehouse is not a simple superposition of ordinary high temperature storehouse and air conditioning equipment. In order to adjust the gas composition in the storehouse quickly, it is necessary to ensure that the quick freezing storehouse has good air tightness. This has been confirmed by the theoretical research and a large number of practical experience of quick freezing warehouse.

The refrigerant charge is insufficient. At this time, just add enough refrigerant.Test results,During the installation of polystyrene storehouse, the Perpendicularity Error of wall plate shall be corrected while the top storehouse plate is installed. The length of the top warehouse plate shall be mm shorter than the surface of the wall plate. After the installation of the top warehouse plate, the mm gap shall be marked with foaming material to ensure the sealing performance of the warehouse body.Air tightness test: system air tightness test, also known as leak detection process, is the last link of commissioning. This work can be divided into pressure, vacuum and ammonia filling leak detection stages.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.Orleans,Insufficient refrigeration dose and capacity in the system: there are two main reasons for insufficient refrigerant circulation,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 important to select materials with good thermal insulation.
