and then sent to the warehouse for cooling. The advantages of air cooling are rapid cooling

Indirect cooling is that the air in the warehouse is pumped into the air cooling device by the blower. The air is absorbed by the evaporation pipe circling in the cooling device, uniform temperature in the warehouse, and can bring harmful gases such as carbon oxide out of the warehouse during storage.The average service life of rigid polyurethane insulation structure with stable quality, long service life and high comprehensive cost performance can reach more than years under normal use and maintenance conditions. Under the normal service conditions during the service life of the structure, or electrochemical corrosion, as well as the growth of insects, fungi or algae or rodents.Judiapa,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.Kg to kg / m, and the steel plate thickness generally needs to be more than . mm to meet the standard. On the market, the main raw materials of special cold storage board for cold storage project are polyphenylene, polyethylene and polyphenylene grease. The density of thermal insulation material foamed by polyphenylene is thin, and the thermal insulation coefficient is not very high; After a certain ratio of polyethylene, it can foam cold storage insulation materials with appropriate density and good thermal insulation effect, and has high load-bearing capacity; Polyphenylene resin has strong water absorption, but poor heat insulation. Therefore, the polyurethane sandwich board with very good performance belongs to the polyurethane sandwich board. Although it is slightly higher, the polyurethane board has very good thermal insulation performance and does not absorb moisture.Kahramanmaras,The exhaust temperature of the compressor equipment is often. When the season changes and the temperature difference changes greatly, pay attention to it. If the machine is abnormal it needs to be checked in time.For water-cooled units, the cooling water shall be replaced frequently, and whether the running, emitting, dripping, leakage and other conditions of the water supply system exist.Connect the refrigeration system. Wires and copper pipes shall be used to connect the refrigeration unit, electric control system and other components of the cold storage. The connecting pipes shall be closely connected, and corresponding thermal insulation and protection measures shall be taken.

The installation of top warehouse plate should be carried out alternately with the installation of wall plate, and the wall plate should leave a gap for withdrawing construction equipment; During the installation of the top warehouse plate, and the rivet spacing shall be mm; According to the design drawings, if there are supporting beams, columns and supporting steel frames in the warehouse, the setting out and positioning shall be carried out and accurate and clear marks shall be made according to the requirements of the design drawings; Weld or install the support beam, column, support steel frame, etc., and the welded junction shall be moisture-proof and treated according to the drawing requirements.Compared with the logistics engineering design of ordinary commodities, the logistics refrigeration engineering commonly used in the circulation of fresh food should follow more stringent design specifications and use requirements so as to maintain the freshness of circulation and prolong the freshness period of fresh food. In recent years, with the frequent cross regional trade,JudiapaBuy cold storage installation, KFC refrigeration has received more and more demand in the design and construction of logistics refrigeration engineering. What are the basic functions of logistics refrigeration engineering in design?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 people's retained items more convenient and reliable. With the continuous development of material technology, today's 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.consumption,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.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, 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.

Cold storage, compressor overload, lack of refrigerant, low pressure too low, excessive air intake, compressor jamming.recommend,However, long-term continuous operation will inevitably lead to equipment aging so reasonable maintenance is particularly important.Check whether the compressor phase current is stable.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, good waterproof performance, 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.JudiapaInstallation of unit electrical box: the unit electrical box shall be installed near the unit; Vertical installation. If the unit is installed on the top of the warehouse, the distance between the box bottom and the top of the warehouse must be & amp; gt; mm; The electrical box can be fixed on the building wall or on the angle steel frame.Frequently observe the operation state of the heart compressor of the cold storage equipment and its exhaust temperature. During the season change operation,JudiapaInstallation design of medical cold storage, pay special attention to the operation state of the system and adjust the liquid supply and condensation temperature of the system in time.There should be excellent drainage pipe standard around the warehouse, the soil temperature should be low, there should be interlayer under the cold storage, and maintain good natural ventilation. Maintaining dryness is very important for the cold storage. In addition, before the construction of the cold storage, the tap water pipeline shall be paved and the FRP cooling tower shall be built.
