Precautions for purchase and shipment when using the medical cold storage project, the speed must be strictly guaranteed during the purchase and shipment of products. If the temperature of the medical cold storage is about degrees the opening time must be strictly within minutes. If the temperature of the medical cold storage is left and right degrees, the opening time can not be too high, strictly within minutes.Points of multi-storey cold storage: small, which can save land; When the storage capacity is the same, the surface area of the outer enclosure structure is smaller than that of the single-layer cold storage, so that the cold consumption can be reduced, the dry consumption of food can be reduced, and the machinery and equipment cost and operation and management cost can be reduced accordingly. At the same time, due to the saving of thermal insulation materials, the civil construction cost per unit area is low and the investment cost is small; The multi-storey location can be reasonable, such as the cooling room can be used as the cold storage room, etc.St Martin,Does the unit location meet the relevant conditions? Whether the heat dissipation and pipe length can meet the requirements.In order to ensure the safety of construction and cold storage operation, the span between the top storage plate supports (lifting points) shall comply with the following provisions: the polystyrene top storage plate (mm thick) has a very large span of M, and the polyurethane top storage plate (mm thick) has a span of m.Ouarzazat,For the ground insulation of large cold storage, we can that the ground insulation of medium-sized cold storage is more complex than that of small cold storage, and the ground insulation operation of large cold storage with larger warehouse area will be more complex. The common operations are as follows: first lay the ventilation pipe to prevent the ground from freezing drum cracking, then lay the XPS extruded plate (staggered laying is required when laying the extruded plate), then lay the moisture-proof and vapor barrier on the upper and lower sides of the extruded plate, then pour the reinforced concrete (generally at least cm thick), and then make the emery floor or epoxy floor according to the requirements. Among them, the XPS extruded plate is also laid according to the warehouse temperature. For example, the XPS extruded plate with thickness of ~ mm needs to be laid in the general low-temperature cold storage, while the XPS extruded plate with thickness of ~ mm can be laid in the high-temperature cold storage.Drainage measures shall be provided for the villa room and overhead layer of the road surface of the cold storage engineering building.For the flushing (thawing) drainage pipe in the cold room with different temperature, an exhaust valve equipment shall be set before connecting the flushing (thawing) drainage pipe.

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, and the raw materials can be sprayed into the brick or concrete warehouse of the cold storage to be built immediately. After shaping, it is both waterproof and thermal insulation. Thermal insulation materials include polyurethane, 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, but the cost is low.Hot gas defrosting, the heat released when the superheated steam of the compressor condenses to melt the double layers on the surface of the evaporator. It is characterized by strong applicability and reasonable energy. For the ammonia refrigeration system, the oil accumulated in the evaporator can be washed out while defrosting, but the defrosting time is long which has a certain impact on the storage temperature, and the sub regulation station of the refrigeration system is complex.Simple refrigeration is based on the volatilization of refrigerant in the condenser of the cold storage, so as to cool the refrigerant, and then input the refrigerant into the box or building of the refrigeration equipment to cool the air according to the heat exchanger. This kind of refrigeration has slow cooling speed, so it can only be used in less places,St MartinCold storage of drugs,Fault phenomenon: high current or tripping during unit startup, and problems of user air switch; Input voltage is too low; The star angle conversion interval is too short (it should be ~ seconds); Hydraulic cylinder failure (no reset); Intake valve failure (too large opening or stuck); Loose wiring; Host failure; Main motor fault; TR time relay is broken (relay unit).Here we focus on polyurethane. Polyurethane is an ideal cold storage material in the cold storage project. Superior bonding properties make the foam and metal panels form a solid whole, so that no other adhesive materials are needed. When polyurethane is used as a cold storage project, rigid polyurethane foam is formed between the panels of the storehouse panel, and then solidified and pressed to form a multi shape storeboard, because the metal plate can roll out different waveforms, so that the overall rigidity is stronger and the bearing capacity is higher. Polyurethane filler board can meet the firmness and physical requirements of exterior wall and can be used in various cold storage projects. It is technically feasible and cost-effective. Yuanbao refrigeration believes that polyurethane is one of the new cold storage materials with great development prospects in the future. The thermal insulation materials of cold storage engineering should not only have good thermal insulation performance, but also be economical, applicable and environmental friendly. To ensure the smooth progress of our cold storage project, we should not only inquire about the raw materials of the cold storage, but also the types of cold storage. The common cold storage plates mainly include the following types,St MartinInstallation of fruit and vegetable fresh-keeping cold storage, namely stainless steel plate, color zinc steel plate, salted steel plate, embossed aluminum plate and mm galvanized standard floor plate.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.

The selection of equipment for the construction of equipment cold storage is closely related to the size, type and budget of the cold storage.reform,Before the acceptance and delivery of the project, it shall be treated. There shall be no obvious scratch on the board surface.Evaporator is not only an exchanger for refrigeration and bulk cooling, but also a very important one. Its task is bulk cooling. It is mainly used for refrigeration and heat absorption in fresh-keeping warehouse. In the long-term work of the fresh-keeping warehouse, the fins of the evaporator will also be covered with dirt, mostly pasted with some sundries of the products. It is specialized in products and renewable resources. Its business includes: cold storage installation, cold storage installation, cold storage construction,St MartinPharmaceutical refrigeration equipment, fruit fresh-keeping cold storage, medical cold storage. In addition, dust and other things, but reaching a certain thickness will have an impact on the cooling of the fresh-keeping warehouse, If the refrigeration of the fresh-keeping warehouse becomes poor, the refrigeration oil and drying filter shall be replaced times after the operation of the cold storage equipment. Replacement after half a year. Depending on the circumstances.St Martin timely handle the overhaul and maintenance of the refrigeration compressor in the cold storage: generally,Initial stage of cold storage equipmentCold storage is fireproof, flame retardant and high resistance. Professional cold storage installation, cold storage installation, cold storage construction, fruit preservation cold storage, medical cold storage and other special products, old brands price advantages and guaranteed quality. Polyurethane is a flame retardant self extinguishing material after adding flame retardant. Its softening point can be above degrees Celsius and will only be decomposed at higher temperatures. In addition, the ash formed on the surface of polyurethane will be in its foam, and this ash will help isolate the foam below. It can effectively prevent the spread of fire. Moreover, polyurethane will not produce harmful gas at high temperature. - floor installation of cold storage: first level the floor, then install the floor, select a beautiful floor and put it in a conspicuous place and do a good job in the floor and evaporator drainage system.
