What is a 4-door industrial refrigerator?
A 4-door industrial refrigerator is a specialized refrigeration equipment used for storing large quantities of food and goods in restaurant kitchens, industrial kitchens, or school cafeterias, etc. With this equipment, food can be better preserved, extending its shelf life while ensuring quality. Compared to 2-door industrial refrigerators, 4-door industrial refrigerators operate with higher capacity and efficiency.
Structure of a 4-door industrial refrigerator
The refrigeration system of a 4-door industrial refrigerator consists of the following basic components:
Evaporator System
The evaporator system acts as a heat exchanger between the refrigerant condensing and the cooling medium (water, air). Its task is to dissipate the heat of the condensing refrigerant into the environment.
The evaporator of industrial refrigerators is typically made of large steel tubes with 1 or 2 coils; heat transfer fins made of circular or square steel plates. The structure of the evaporator of an industrial refrigerator includes one end fitted into the compressor discharge head, the other end fitted into the filter before connecting to the suction line. It is usually positioned at the rear of the refrigerator or can be placed on both sides while ensuring the best air circulation and aesthetic appearance.
Compressor
Usually, a single or double piston compressor, operating on the principle of converting rotary motion into reciprocating motion through the piston. The compressor is responsible for sucking the refrigerant vapor produced at the evaporator and maintaining stable pressure at low temperatures. Then it compresses the vapor from the evaporating pressure to the condensing pressure and pushes it into the condenser.
Refrigerant (Gas)
Refrigerant is the volatile liquid placed inside industrial refrigerators to create cold temperatures. There are various types of refrigerant gases used in the refrigeration industry, such as pure ammonia (NH3), carbonic (CO2), hydrocarbons (CxHy), and their derivatives substituted by halogen elements instead of hydrogen, such as chlorine (Cl) or fluorine (F). The symbol for refrigerant gas on industrial refrigerator equipment is R – an abbreviation for Refrigerant.
Condenser
The condenser is a heat exchanger between the refrigerant and the cooling environment. Its function is to absorb heat from the cold environment and supply it to the refrigerant boiling at low temperatures. It is installed immediately after the suction line or expansion valve and placed before the compressor.
Operating principle of industrial refrigerators
The operating principle of a 4-door industrial refrigerator involves utilizing dry steam to absorb heat. Specifically:
- The compressor of the refrigerator compresses the refrigerant to high pressure and high temperature. At this point, the refrigerant is in a gaseous state.
- After passing through the compressor, the refrigerant is pushed to the condenser. Here, the refrigerant at high pressure and temperature is cooled by air and condensed into a liquid at high pressure and low temperature. Heat dissipation occurs during condensation, so touching the side of the refrigerator will feel the heat dissipation.
- Next, the liquid refrigerant at high pressure passes through the expansion valve. Under the action of the expansion valve, the refrigerant changes from high pressure and low temperature to low pressure and low temperature.
- Then, the refrigerant absorbs heat from the air inside the refrigerator to vaporize. During this process, the liquid-vapor absorbs heat from the air inside the refrigerator and cools the environment inside.
- The refrigerant returns to the compressor and continues the operating cycle in a similar manner.
Features and Applications of 4-door Industrial Refrigerators
- These devices with multiple cooling functions are used for rapid cooling and preservation, suitable for storing and stockpiling food items: preserving fresh produce, various fruits to keep vegetables fresh; storing pre-prepared food (cooked food) to prevent spoilage over extended periods.
- The refrigerators are primarily used for food storage areas in restaurants, hotels, resorts, schools, hospitals, etc. These are places with a high demand for daily storage of large quantities of food.
