How to configure the cold storage refrigeration equipment

How to configure the cold storage refrigeration equipment How to configure the cold storage refrigeration equipment? As a total solution provider for cold storage, Sike Refrigeration has rich experience in the installation of cold storage refrigeration equipment, and can customize exclusive refrigeration equipment for your cold storage. Today, the editor will explain to you based on the configuration of the cold storage refrigeration equipment. 1. In general, fully enclosed compressors are used for small refrigerators. Medium-sized cold storage generally chooses semi-hermetic compressors. Large-scale cold storage uses semi-hermetic compressor or screw compressor. 2. Evaporator: In general, the high-temperature warehouse uses a fan as the evaporator, which is characterized by a fast cooling speed, but it is easy to cause moisture loss of cold storage; medium and low-temperature cold warehouses are mainly made of seamless steel tubes. The characteristic is that the constant temperature effect is good, and the cold storage can be timely. 3. Condenser: The condenser has air cooling, water cooling and air and water combined cooling methods. Air cooling is limited to applications in small cold storage equipment, and water-cooled condensers can be used in all forms of refrigeration systems. 4. Thermal expansion valve: The thermal expansion valve is divided into an internal balance expansion valve and an external balance expansion valve. The inlet pressure of the evaporator is felt under the diaphragm of the internal balance expansion valve; the one under the diaphragm of the external balance expansion valve is felt. It is the outlet pressure of the evaporator. 5. Liquid storage tank: store freon to ensure that the refrigerant is always saturated. 6. Solenoid valve: to prevent the high-pressure part of the refrigerant liquid from entering the evaporator when the compressor is stopped, to prevent the low pressure from being too high when the compressor is next started, and to prevent the compressor from liquid shock. In addition, when the temperature of the cold storage reaches the set value, the thermostat acts, and the solenoid valve is de-energized. When the low-pressure pressure reaches the set value of the shutdown, the compressor stops. When the temperature in the cold storage rises to the set value, the thermostat acts and the solenoid valve gets The compressor starts when the low-pressure pressure rises to the compressor start-up setting value. 7. High and low pressure protector: protect the compressor from high pressure and low pressure. 8. Thermostat: It is equivalent to the cold storage brain controlling the cold storage refrigeration on and off, defrosting, and the fan on and off. 9. Dry filter: filter impurities and moisture in the system. 10. Oil pressure protector: ensure that the compressor has enough lubricating oil. 11. Oil separator: Its function is to separate the lubricating oil in the high-pressure steam discharged from the refrigeration compressor to ensure the safe and efficient operation of the device. According to the oil separation principle of reducing the airflow speed and changing the airflow direction, the oil particles in the high-pressure steam can be separated under the action of gravity. Generally, the air flow speed is below 1m/s, and the oil particles with a diameter of more than 0.2mm contained in the steam can be separated. There are four types of oil separators commonly used: washing, centrifugal, packing and filtering. 12. Evaporator pressure regulating valve: It is to prevent the evaporator pressure (and evaporation temperature) from falling below the specified value. Sometimes it is also used to adjust the evaporator pressure to the force to adapt to changes in load.
