Verniachica Mineral CityDesign and installation cold storage installation companyHow to carry out seasonal maintenance

Install the electric control system. The electric control system of the cold storage mainly includes electric controller, electric door, and the power supply or backup power supply can be used as required. The circuit shall have reasonable discharge and corresponding protective measures.In order to prevent damage to the cold storage, it is necessary to lay some foam on the floor of the cold storage tank.Verniachica Mineral City,The area of wires in the conduit shall not exceed %.Secondly, since the cooling of the compressor is not continuous, the multi work operation at night can be selected if possible. When working at night, the external temperature is low, the cooling water temperature is reduced, and the condensation pressure and condensation temperature are reduced. The cooling capacity of the sampling system, coupled with the equal role of the cold storage board reduces the power operation of the compressor and achieves the purpose of energy saving.aqaba ,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, namely stainless steel plate, color zinc steel plate, salted steel plate, embossed aluminum plate and mm galvanized standard floor plate.If there is more air or refrigerant oil in the evaporator, the heat transfer effect will be reduced: once more refrigerant oil is attached to the inner surface of the evaporator heat transfer tube, the heat transfer coefficient will be reduced. Similarly if there is more air in the heat transfer tube, 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.The quick freezing storehouse of vegetables and fruits is not suitable to use exhaust cooling, because the gas in the quick freezing storehouse needs to be circulated and dispersed regularly to avoid carbon oxide poisoning caused by high concentration of carbon oxide in local areas. Therefore, 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.

The physical properties of polyurethane insulation board are relatively good, which can meet different needs. The polyurethane insulation board is also strict in the selection of materials. It is a special product manufacturing enterprise integrating R & D, and service. It has long been specialized in cold storage installation, cold storage installation, cold storage construction, Polyurethane insulation board has also become one of the main exterior wall materials.Water defrosting: spray the defrosting water spray device on the surface of the evaporator to melt the double layer,Verniachica Mineral CityCold storage installation, and then through the drainage pipe. This scheme has high efficiency, simple operation procedure and small temperature fluctuation. From the perspective of energy, the cooling consumption per square meter of evaporation area can reach -kj. Water frost flushing is also easy to make fog in the warehouse cause dripping water on the ceiling of the cold room,Verniachica Mineral CityWhich one is better for general cold storage installation, and reduce the service life.When installing the polyurethane insulation board, the adhesion between the panel of the polyurethane insulation board and the thermal insulation material is short and often high.Analysis project,Refrigeration system: refrigeration system is the core part of cold storage design. It is the key to determine the economy, environmental protection and performance of cold storage.Floor insulation of medium-sized cold storage the structure of medium-sized cold storage is what we often call the surface, that is, the top and wall are made of color steel plate / stainless steel with appropriate thickness of polyurethane and other insulation materials, while the ground needs to be insulated separately. At present, the common operations in the market are: laying the ground with XPS extruded board, laying moisture-proof and steam isolating SPS materials above and below the extruded board respectively, and then pouring concrete or reinforced concrete.General quick-frozen warehouses are mostly cooled by refrigeration mechanisms, and those with very low gasification temperature are used as coolant to evaporate under low pressure and mechanical conditions,Verniachica Mineral CityHow much is the cold storage, so as to absorb the heat in the warehouse, so as to achieve the purpose of cooling and reduction.

Regular oil discharge, descaling and air discharge: when there is a .mm thick oil film in the evaporator coil, in order to maintain the set temperature requirements, the evaporation temperature will decrease by ℃ and the power consumption will increase by more than ; When the scale on the water pipe wall in the condenser reaches mm, the condensation temperature will rise by ℃ compared with the original temperature, and the power consumption will increase. When the refrigeration system is mixed with non condensable gas and its partial pressure reaches .mpa,Feasibility of the design scheme: the design of the quick-frozen warehouse can not be taken for granted. Many restrictive factors should be considered. In practice, a reasonable design scheme should be given according to local conditions. For example, the large-scale quick-frozen warehouse I built for my family should be refrigerated with ammonia in theory, because the refrigeration capacity of ammonia refrigeration is large, and I found that it is cheap to replicate cold through actual field investigation.Scroll refrigeration unit: at present scroll refrigeration unit is mainly in fully enclosed structure, which is mainly used in air conditioning (heat pump)When outdoor air enters the cold storage body, it will not only increase the cold consumption of the cold storage, but also bring water into the warehouse. The condensation of water will lead to the building structure, being damaged by moisture and freezing. Therefore, a moisture-proof and heat insulation layer should be set to keep the cold storage board building moisture-proof and air-proof performance and good sealing.Verniachica Mineral City,At ordinary times, users should check the sealing degree of the gap of the cold storage, and notify the cold storage for maintenance in time if damaged parts are found.During the use of cold storage, attention shall be paid to the collision and scratch of the storage body to avoid the depression and corrosion of the storage plate, which will seriously reduce the local thermal insulation performance of the storage body.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, and use the cold air to cool the objects that need to be cooled. This kind of refrigeration is characterized by faster cooling speed, small heat conduction temperature difference and simple system software, so it is widely used.
