Compression refrigerator is commonly used, which is mainly composed of compressor, condenser,Barclay Nettlefold Professional installation manufacturer of cold storage, throttle valve and evaporation pipe. According to the way of evaporation pipe device, it can be divided into direct cooling and indirect cooling. Direct cooling the evaporation pipe is installed in the refrigerated warehouse. When the liquid coolant passes through the evaporation pipe, it will directly absorb the heat in the warehouse and cool down.The quick freezing storehouse of vegetables and fruits is not suitable to use exhaust cooling, but use fan to supply air for refrigeration, in the quick freezing warehouse, the refrigeration equipment needs to be used together with the air conditioning equipment. The selection of refrigeration equipment is different from that of low-temperature freezer and ordinary quick freezing warehouse.Barclay Nettlefold ,After the installation of the controlled atmosphere storage another important finishing work is to purge the whole system. Compressed air will clean out the impurities remaining in the controlled atmosphere storage, which plays a key role in the use of the controlled atmosphere storage.In order to prevent damage to the cold storage, it is necessary to lay some foam on the floor of the cold storage tank.Nkamp,The insulation board of the cold storage adopts polyurethane double-sided color steel plate. The main effect of this cold storage insulation board is good sealing performance, insulation effect and moisture-proof effect so as to ensure the refrigeration effect of the cold storage. The electric cold storage door is adopted for the cold storage door, and the cold storage management personnel can timely and effectively open and close the door when entering and leaving, so as to avoid the loss of refrigeration capacity of the cold storage.Polyurethane foam foam dimensional stability: cold storage polyurethane foam in severe temperature changes or at a relatively low temperature will appear dimensional changes (as contraction), the size changes often reflect bubble cracking or falling off, and these will inevitably affect the normal use of cold storage. In addition to regular simulation of performance testing, more emphasis is placed on the selection of high quality materials: special energy polyether compound use, so that the foam body mesh structure, greatly improving the foam low temperature resistance. At present, polyether commonly used in spraying materials contains a large number of functional components, and a large number of linear structures formed after reaction are difficult to be stable at low temperature; The use of the energy crosslinking agent also greatly improved the dimensional stability of the foam. The selected polyether adopts catalysis in the production stage, and the reaction is complete, so that the polyether maintains a high reaction rate (that is, it can react completely with black material); Some manufacturers in order to achieve foam appearance does not produce deformation phenomenon and add a hole component to foam material, reduce the bubble closed hole rate, achieve the effect of stable size,Barclay Nettlefold Fresh and cold storage installation company, but it has sacrificed the thermal insulation performance of polyurethane cold storage insulation material foam.The importance of regular oil discharge, descaling and air discharge in the refrigeration system of the warehouse.

. Maintenance of food cold storage. In a position convenient for operation outside the door of the refrigerator room, a main switch for cutting off the power supply of the refrigeration compressor shall be set. This switch shall be able to stop the operation of the refrigeration compressor, and relevant signs shall be set. If the mechanical panel is set in the main room, a button switch shall be added next to each refrigeration compressor.System blowdown: the standby air compressor is used. When the air compressor cannot be solved, the ammonia compressor can be used instead.The bacterial action of acid disinfectants is mainly to coagulate the protein in the bacteria. Common disinfectants include lactic acid, bleach, formalin, etc. Specifically, after the fish comes out of the freezer, clean the frost layer on the evaporating pipe group and keep the storehouse temperature below degrees Celsius. Then, according to the volume of ~ grams per cubic meter volume of the frozen storeroom, the storeroom door is closed tightly with the sprayer, and the blower is started intermittently, so that the vinegar evaporates and flows in the storehouse, the temperature and temperature difference parameters of the cold storage shall be customized according to the user's requirements. After understanding the technical parameters of the cold storageWhether the parameters of refrigeration equipment are consistent. When the cold storage leaves the factory, set the parameters on the refrigerator. During use, the air humidity is high and the defrosting interval is long. The common cold storage boards of cold storage include mm, mm, mm, mm and mm polyurethane thermal insulation boards, color steel tiles, stainless steel plates, salt thick steel plates, embossed aluminum plates, polyurethane spraying, etc. on both sides or single and double sides, more general color steel tiles are produced and processed into hidden grooves, which have light weight, high compressive strength, good fire resistance, corrosion resistance and aging resistance, The cold storage board is simple and convenient to assemble, and is a wide range of raw materials selected for the heat insulation and heat preservation of the cold storage. The cost of stainless steel plate and salt plate increases, and it is also easy to deform and damage the appearance.The refrigeration equipment in the fresh-keeping environment of the quick-frozen warehouse mostly adopts the single-stage compression refrigeration system,Barclay Nettlefold Where is the cold storage installed, with freon as the refrigerant. The evaporation mode in the warehouse is the cooling fan, which can be ceiling type. If the number of warehouses is small and the volume does not exceed cubic meters, the refrigeration mode of the warehouse machine can be considered. If there are a large number of warehouses, 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 temperature and humidity in the warehouse shall be kept uniform without movement; Try to finish the food in the warehouse at one time.Executive standard,Installation of cold storage, construction 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, so as not to damage the ground and affect the service life of the cold storage.The cooler on the refrigeration unit is very easy to be dirty, so it should be cleaned on time according to the specific situation. To maintain stable heat conduction and practical effect. Good heat removal and cooling. There is no need to accumulate dirt around the refrigeration unit.If there is more air or refrigerant oil in the evaporator, if there is more air in the heat transfer tube the heat transfer coefficient will be reduced. Similarly, the heat exchange area of the evaporator will be reduced, the heat transfer efficiency will be significantly reduced, and the decline rate of warehouse temperature will be slowed down.Barclay Nettlefold ,During production in the production workshop, the unit weight of Pu warehouse board shall not be less than the unit weight required by the project, not less than & plusmn; kg/m.The three-dimensional automatic cold storage adopts a computer, which can complete the loading, unloading and stacking in the storage, the control of storage temperature and the operation of refrigeration equipment.Watertight polyurethane rigid foam has low water absorption, good permeability to water vapor, and state of foam pores. It is not connected with each other, and the obturator rate is more than %. It is a dense microporous foam material, which is more dense than the surface of the air, and is not easy to permeate. It is an hydrophobic material.
