DewarInstallation telephone of fresh-keeping cold storage,

Another reason is that there are many refrigerants in the system. In this case, find the leakage point first, focus on the connection of each pipeline and valve, repair the found part, and then fill in sufficient refrigerant.All wiring shall be neat. All switches and keys shall be opened and closed sensitively, reliably and accurately. Special connectors shall be used for wiring,DewarSmall installation of freezer, and power protection shall be provided for the box and each power branch.Dewar,Expensive, high machining precision of body parts; High noise during compressor operation; Screw compressor can only be used in medium and low pressure range, not in high-pressure occasions; Due to large fuel injection and complex oil treatment system, there are many auxiliary equipment of the unit.How to maintain the refrigeration compressor in the cold storage in order to prolong its service life and reduce the occurrence of faults in the use process. The refrigeration compressor in the cold storage needs regular maintenance. Here we introduce the maintenance of the compressor in the cold storage.Khiwa,The foaming technology of polyurethane with strong stability 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, it can bear various internal and external combined loads such as wind force, self weight and normal collision,DewarMedical cold storage installation, and the insulation layer still does not separate and fall off from the carrier layer and remains stable in the state.Pay attention to the energy saving of the lighting system: the lighting of the cold storage should be considered comprehensively according to the area, height and warehouse temperature of the cold storage on the basis of safety, science and rationality, from the perspective of energy saving and environmental protection. The lighting in the cold storage is concentrated in the working area.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, small heat conduction temperature difference and simple system software, so it is widely used.

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.Electrothermal defrosting: the electrothermal element defrosts the controlled atmosphere reservoir. The management system of controlled atmosphere storage is simple easy to operate, easy to realize automation, but it consumes more power.What should be considered in building a cold storage? In these aspects, food cold storage is a systematic project of artificial refrigeration to ensure food quality and reduce food decay in a low-temperature environment. Refrigeration technology affects the design of food cold storage, meets the needs of refrigeration technology, convenient production, energy saving and cost reduction. What problems should be considered in the construction of food cold storage?system,The new cold storage material is made of rigid polyurethane or polystyrene foam insulation sandwich panel, which is made by high pressure foaming process and can be made into various lengths and specifications to meet the different requirements of the users.Generally speaking, the construction of cold storage is to ensure the quality of buildings with its strict heat insulation, sealing, firmness and frost resistance.Anti odor floor drain shall be set on the pavement of refrigeration room and refrigeration unit room, and the height width ratio of floor drain water seal shall not be less than mm. The elevator shaft, electronic pit and other places convenient for drainage shall be provided with drainage and equipment to avoid backflow of water.

Cold storage has good fire and flame resistance. After adding flame retardant, polyurethane is a kind of flame retardant and self extinguishing material. If it is burned by fire, it can be carbonized, unlike flow burning and flashover like extruded board, which can effectively prevent fire spread. In particular, it can be closed as a whole after fire prevention treatment to form non combustible products.manufacturer,Polystyrene foam: polystyrene foam is a new type of synthetic thermal insulation material. It is a kind of plastic, strong heat insulation effect and excellent low temperature resistance. However light weight due to its cold shrinkage, it is not very convenient for installation.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, 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?Moreover, polyurethane does not produce harmful gas at high temperature.Dewar,Improper adjustment or blockage of throttle valve, too large or too small refrigerant flow: improper adjustment or blockage of throttle valve will directly affect the refrigerant flow into evaporator. When the throttle valve is opened too large, the refrigerant flow is too large, the evaporation pressure and evaporation temperature also increase, and the decline rate of warehouse temperature will slow down; At the same time, when the throttle valve is opened too small or blocked, the refrigerant flow will also decrease, the refrigeration capacity of the system will also decrease, and the decline rate of warehouse temperature will also slow down.Before the acceptance and delivery of the project, the board surface shall be wiped clean. If there is any scratch, and then sent to the warehouse for cooling. The advantages of air cooling are rapid cooling, uniform temperature in the warehouse
