How to configure the cold storage refrigeration equipment? The full set of refrigeration equipment installation quotation for Yuncheng cold storage, okmarts.com Refrigeration, as a cold storage overall solution provider, has rich experience in cold storage refrigeration equipment installation, and can customize exclusive refrigeration equipment for your cold storage. Cold storage in Yuncheng area and surrounding areas can be reserved For door-to-door measurement, Cheng Sheng Refrigeration will also provide a full set of cold storage installation quotations. So today, Cheng Sheng Xiaobian will explain to everyone based on the configuration of the cold storage refrigeration equipment.

　　 1. Under normal circumstances, small-scale cold storages use hermetic compressors. Medium-sized cold storage generally uses semi-hermetic compressors. Semi-hermetic compressors or screw compressors are used for large-scale cold storage.

2. Evaporator: Under normal circumstances, the high-temperature warehouse uses a fan as an evaporator, which is characterized by a fast cooling speed, but it is easy to cause moisture loss in the refrigerated products; the medium and low-temperature cold storage mainly uses the evaporator pipe made of seamless steel pipe. The characteristic is that the constant temperature effect is good, and can store the cold in time.

　　3. Condenser: The condenser has air cooling, water cooling and air and water cooling methods. Air cooling is limited to the application of 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 internal balance expansion valve and external balance expansion valve. What is felt under the diaphragm of the internal balance expansion valve is the inlet pressure of the evaporator; while that felt under the diaphragm of the external balance expansion valve Is the outlet pressure of the evaporator.

　　 5. Liquid storage tank: store Freon to ensure that the refrigerant is always saturated.

　　6. ​​Solenoid valve: prevent the high-pressure part of the refrigerant liquid from entering the evaporator when the compressor is stopped, avoiding the low pressure when the compressor is started next time, and preventing the compressor from liquid shock. In addition, when the temperature of the cold storage reaches the set value, the thermostat will act, the solenoid valve will lose power, and the compressor will stop when the low pressure reaches the stop set value. When the temperature in the cold storage rises to the set value, the thermostat will act and the solenoid valve will be When the low-pressure pressure rises to the compressor start-up setting value, the compressor will start.

　　7. High and low pressure protector: protect the compressor from high pressure and low pressure.

　　 8. Thermostat: It is equivalent to the brain of the cold storage that controls the opening and stopping of the cold storage refrigeration, defrosting, and the opening and closing of the fan.

　　 9. Filter drier: filter impurities and moisture in the system.

　　 10. Oil pressure protector: to 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 are separated under the action of gravity. Generally, if the air flow velocity is below 1m/s, the oil particles with a diameter of 0.2mm or more contained in the steam can be separated. There are four types of oil separators commonly used: washing type, centrifugal type, packing type and filter type.

　　 12. Evaporator pressure regulating valve: It prevents the evaporator pressure (and the evaporation temperature) from falling below the specified value. Sometimes it is also used to adjust the pressure of the evaporator to adapt to changes in load.
