commercial refrigeration structure and principle
Structure and working principle of ordinary commercial refrigeration
Ordinary commercial refrigeration refers to a direct-cooled commercial refrigeration that uses a reciprocating compressor. This type of commercial refrigeration has only one mechanical thermostat. Two-door, three-door, and four-door refrigeration and freezing commercial refrigeration. 1. Ordinary commercial refrigeration The working principle of the refrigeration system Ordinary commercial refrigeration generally uses reciprocating compressors with a typical refrigeration system structure. The work of the refrigeration system is controlled by the electrical system, and the basis of electrical system control is based on user settings.
describes the work of the refrigeration system. 1. The compressor motor is the heart of the refrigeration system. It is used to convert heat energy and reciprocate the refrigerant in the system. It sucks in the refrigerant that has absorbed heat from the evaporator and becomes a gaseous refrigerant, which is compressed into high temperature and high pressure. The gas is delivered to the door to the frame anti-exposure tube. This process is powered by a motor, that is, electrical energy is converted into mechanical work through the motor, and the mechanical work is converted into thermal energy through the compressor.
2. The anti-dew pipe is hidden around the cabinet door. The refrigerant is compressed in the compressor to become a high-temperature and high-pressure gas, and is sent to the condenser through the anti-dew pipe, so that the cabinet door frame is heated to higher than room temperature to avoid hot and humid seasons Condensation on the outer surface of the door frame.
3. Condenser Because the condenser pipe is very long, the high-pressure, high-temperature gas refrigerant discharged from the compressor passes through it and transfers heat to the air to dissipate heat. The temperature gradually drops and condenses into a liquid refrigerant.
4. The liquid refrigerant discharged from the condenser of the filter drier is first dried to absorb the moisture in the refrigerant and filter the tangible dirt, and then sent to the capillary tube. In order to prevent impurities and moisture from entering the capillary with small aperture to form a blockage, affecting the flow of refrigerant.
5. The capillary capillary throttling aperture is very thin, generally 0.5mm-lmm, the liquid refrigerant from the filter drier is restricted when flowing through the capillary, and the flow is controlled to make it completely and fully liquid.
6. Evaporator The liquid refrigerant enters the evaporator with a large pore size through a capillary tube with a very small pore diameter. The pressure suddenly decreases, causing the boiling point to drop and evaporate into gas, and absorb heat from the surrounding (freezing and refrigerating rooms) during evaporation, thereby reducing Freezing and cold storage room temperature. The refrigerant vaporized by the evaporator is sucked in by the compressor again, and the refrigerant circulates repeatedly in the system so that the heat in the commercial refrigeration is transferred to the surrounding air through the refrigerant, so that the commercial refrigeration achieves the purpose of refrigeration.
