Brooke in the wildernessInstallation of cold storage and quick freezing storage,

Installation of unit electrical box: the unit electrical box shall be installed near the unit; Vertical installation. If the unit is installed on the top of the warehouse, the distance between the box bottom and the top of the warehouse must be & amp; gt; mm; The electrical box can be fixed on the building wall or on the angle steel frame.Some cold bridge prevention measures shall be taken at the joints between polyurethane insulation boards.Brooke in the wilderness,Condensation pressure if the condenser has poor heat transfer, the condensation pressure will increase and the cooling power will decrease. For cooling, power consumption increases. If the configuration of the cooling system is too small, the heat transfer capacity will be insufficient, resulting in high condensation pressure.It will still decrease. The humidification amount will decrease by % at degrees.Sao Tome and Principe,Cold storage construction: which one is suitable for you? Which one is suitable for you?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.Compression refrigerator is commonly used. It is mainly composed of compressor, condenser,Brooke in the wildernessSmall cold storage installation company, 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.

The lights in the warehouse are not on. Please check whether the switch fails and whether the bulb is damaged. Cut off the power supply when installing the lampshade, and pay attention to the waterproof of the lamp.The machine room shall be kept clean and well ventilated, and the condenser shall be cleaned and masonry removed regularly to ensure the normal and stable operation of the unit.In order to prevent damage to the cold storage,Thermal insulation rigid polyurethane has low thermal conductivity and good thermal performance. When the density of rigid polyurethane is ~ kg / m, the thermal conductivity is only . ~ .w / (m.k), which is the lowest among all thermal insulation materials at present.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.Disadvantages of single-layer cold storage: large; The surface area of the external enclosure structure of the cold storage is large, so the amount of thermal insulation materials is large, the floor anti freezing treatment requires a large amount of work. When the cold storage is built at the water level, it is impossible to deal with it, which is easy to cause horizontal freezing and swelling.

Polyurethane spraying is widely used in large and medium-sized refrigerators. Different well-known brands are produced at different prices,The average service life of rigid polyurethane insulation structure with stable quality it is not high-quality or good goods. This is the result of long-term cooperation.Focus on Development, long service life and high comprehensive cost performance can reach more than years under normal use and maintenance conditions. Under the normal service conditions during the service life of the structure, it will not be affected by drying, or electrochemical corrosion, as well as the growth of insects, fungi or algae or rodents.Pressure leak test: the pressure leak test of the fresh-keeping warehouse system is the same as that of the sewage blowing working sample which is required to be carried out by air compressor. If ammonia compressor is used, a special one shall be designated and the exhaust temperature shall be strictly controlled. When high pressure is applied, the method of segmenting and reducing the pressure difference shall be adopted.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,Brooke in the wildernessHow much is it to install a small cold storage, cold storage installation, cold storage construction, fruit preservation cold storage and medical cold storage. It improves the overall performance of the polyurethane insulation board and enables the polyurethane insulation board to work for a long time, Polyurethane insulation board has also become one of the main exterior wall materials.Brooke in the wildernessIf 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. - precautions for vertical plate of cold storage: vertical plate display. 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.
