1. Compressor: It plays the role of compressing and driving the refrigerant in the refrigerant circuit, and is the power of the refrigeration system.
2. Condenser: It is one of the main heat exchange equipment in the refrigeration system of cold storage. Its function is to cool and condense the superheated vapor of the high-temperature refrigerant discharged from the compressor of the assembled cold storage into high-pressure liquid.
3. Evaporator: The liquid refrigerant evaporates at low pressure and low temperature, absorbs the heat from the freezer and evaporates, and turns into a gaseous refrigerant. The gaseous refrigerant is sucked into the compressor and compressed, and then discharged into the condenser to discharge heat. Basically, the principle of the evaporator and the condenser is the same, the difference is that the former absorbs heat into the storehouse, and the latter exhausts heat to the outside.
4. Liquid storage tank: store Freon storage tank to ensure that the refrigerant is always in a saturated state.
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 principle of oil separation by 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, when the airflow velocity is below 1m/s, 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 type, centrifugal type, packing type and filter type.
