Compression refrigerator is commonly used. It is mainly composed of compressor, condenser, throttle valve and evaporation pipe. The evaporation pipe is installed in the refrigeration warehouse. When the liquid coolant passes through the evaporation pipe, it directly absorbs the heat in the warehouse and cools down.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, 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.St Mary,System blowdown: it is easy to use the standby air compressor. When the air compressor cannot solve the problem, it can be replaced by ammonia compressor, but the exhaust temperature during use shall not exceed ℃, otherwise the oil viscosity will be reduced beyond the flash point and carbon will be formed, thus damaging parts and components.In the cold storage project, the selection of cold storage is related to the overall operation of cold storage in the future. The selection of high-quality cold storage is conducive to the use and maintenance of cold storage. This requires us to inquire more about the warehouse board for cold storage engineering. Before the construction of cold storage project, we should first realize the temperature requirements of cold storage and the importance of cold storage to cold storage. Because the cold storage project has high environmental requirements such as temperature, attention should be paid to the performance and material of the cold storage board when selecting the cold storage board.Tafuna,When installing polyurethane insulation board, ensure that its surface is smooth and flat without scratch and warpage.Floor insulation of medium-sized cold storage the structure of medium-sized cold storage is what we often call the surface, that is, 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.Step of cold storage design: define the volume of the cold storage warehouse. The size of the cold storage should be based on the design of a large number of agricultural products to be stored for a long time. This volume is calculated based on the essential volume of stored goods accumulated in the cold storage, plus the row to row corridors, the indoor space between the pile and the wall, the ceiling and the gap of the packaging house. After the volume of the cold storage is determined the length and height width ratio of the cold storage shall be determined. Necessary auxiliary engineering buildings and equipment shall also be considered in the design of cold storage, packaging and combing room, special tool warehouse, loading and unloading platform, etc.

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 phase electricity of the relative volume shall be built according to the output power of the refrigeration unit. If the cold storage is water-cooled and radiating, the tap water pipeline shall be paved and the FRP cooling tower shall be built.The machine room shall be equipped with oxygen respirator gas mask, gas clothing, rubber gloves, wooden stopper, pipe clamp, acid beverage and other necessary protective and rescue articles, which shall be set in a convenient location, managed by a specially assigned person and used regularly. Relevant personnel shall skillfully master the use of oxygen respirator and personnel rescue.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.production,Now let's analyze the production and use requirements of the cold storage. There is no condensation in the cold storage. Condensation in the cold storage or in the insulation layer is harmful. During the drying process of the new wall or under winter conditions, when the water vapor with high indoor temperature migrates outdoors, it is impossible to condense in the wall due to the obstruction of the cold storage.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, large total heat conduction temperature difference and complex system software,St MaryCold storage installation discipline, so it can only be used in less places, such as brine ice making and cold storage with constant temperature requirements.. 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.

Whether the parameters of refrigeration equipment are consistent. When the cold storage leaves the factory,St MaryWhere to install cold storage specialty, 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 storage, 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, 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.Sales Department,In order to maintain a constant low temperature in the cold storage, attention should be paid to the installation of cold storage panels in Guizhou: the floor, wall and flat roof of the cold storage are laid with a certain thickness of thermal insulation materials to reduce the incoming heat from the outside. In order to reduce the absorption of solar radiation, the surface of the external wall of the cold storage is painted white or light color. Therefore, cold storage building is different from general industrial and civil buildings, and has its unique structure. Cold storage buildings should prevent the entry of air and the diffusion of water vapor.If the relative flow changes little, there is little difference in power consumption among several regulation modes, that is, the regulation mode has little impact on the energy-saving effect, or even does not save energy, but consumes more power due to the existence of the regulation device, and the variable speed regulation curve is close to the ideal curve. Therefore, the variable speed regulation mode is superior especially the energy-saving scheme of variable frequency motor speed regulation is recommended, but the frequency conversion device needs to be added. It is recommended to actively try out the variable frequency speed regulation of small and medium capacity. Due to the high capacity and high voltage variable frequency speed regulation device,St MaryCold storage of professional installation company, the greater the regulation depth, the more significant the energy-saving effect.Families will also be equipped with some simple refrigeration devices. For refrigeration devices such as cold storage, it is very important to select materials with good thermal insulation. Cold storage is a better material selection and in the production process of cold storage, there will be no condensation in the cold storage of the plant. Condensation inside the cold storage or inside the insulation layer is harmful. Irreversible damage or deformation occurs in the new external insulation, and the external surface temperature of the external wall changes sharply. For example, the insulation and sound insulation effects of polyurethane insulation board are relatively good, which can be used in many industries. As we all know, the cold storage has great requirements for the thermal insulation effect of building materials. If the thermal insulation effect of building materials is not good, the cold storage will consume more energy during operation, so a large number of polyurethane insulation boards need to be used in the construction of general cold storage. Next,After the cold storage at the corner is installed, the next cold storage can be installed along the direction of the corner. Adopt the similar installation of Zhang cold storage to install the thermal insulation board of the storage.
