Refrigeration compressor is an important device in the refrigeration system, which acts as the heart of the refrigeration equipment we use every day. From household refrigerators to large industrial refrigeration systems, refrigeration compressor helps maintain optimal temperatures for food, pharmaceuticals, and many other products. This article Tan Long will provide insight into types of refrigeration compressors popular on the market today, from operating principles, applications to how to choose the right compressor for your needs.
Compressors and functions of refrigeration compressors
Refrigeration compressor Not just a device but also a decisive factor in the performance of the work. refrigeration system. The main function of the compressor is to compress the refrigerant from the vapor state to the liquid state, helping the refrigerant circulation mechanism to take place more effectively. When the refrigerant in vapor form is sucked into the compressor, it will be compressed and converted to liquid form to release heat to the outside, then continue to return to the evaporator to create the cooling process.
Refrigeration compressor can be divided into several different types. Each type has its own unique characteristics, serving specific applications. Understanding the types of refrigeration compressors and their functions will help consumers make the right decision in choosing the right device for their needs.
Working principle of refrigeration compressor
Operating principles of refrigeration compressors consists of four main stages: evaporation, compression, condensation and expansion. Each stage plays an important role in ensuring the refrigeration process is continuous and efficient.
The first stage is the suction stage, where the compressor draws low-pressure refrigerant from the evaporator. This is followed by the compression stage, where the refrigerant is compressed by a piston or rotor inside the compressor, increasing its pressure and temperature. The condensing stage sees the high-pressure refrigerant transferred to the condenser, where it releases heat to the surroundings and becomes a liquid. Finally, the liquid refrigerant passes through the expansion valve, reducing its pressure and temperature before returning to the evaporator.
Applications of refrigeration compressors
Refrigeration compressor widely used in many areas of life. In the civil field, refrigeration compressors play a key role in devices such as refrigerators, air conditioners and ice makers. These devices help preserve food and create a comfortable living space for people.
In the industrial sector, refrigeration compressors are used in refrigeration systems for factories, shopping malls, hospitals and the food industry. It contributes to maintaining a safe and efficient working environment.
Besides, refrigeration compressor also plays an important role in the medical field, where it is used to preserve drugs, vaccines and blood. Not only that, refrigeration compressor also supports in preserving agricultural products, prolonging the shelf life of food.
Popular types of refrigeration compressors
On the market today, there are many types of refrigeration compressors with different configurations and operating principles. Types of refrigeration compressors Each has its own advantages and disadvantages, suitable for specific applications. Below are types of refrigeration compressors most popular
Screw compressor
Screw compressor is a popular type of refrigeration compressor, especially in industrial applications. The design of screw compressors is often very complex, but its working efficiency is very high.
Working principle of screw compressor based on two counter-rotating screws, creating pressure and volume changes to move the refrigerant. Thanks to this design, screw compressor capable of continuous operation and high performance even under difficult conditions.
One of the main advantages of screw compressors is their quiet and stable operation. However, the cost of these compressors is often quite high, and they require regular maintenance to ensure optimal performance.
Piston compressor
Piston compressor is the most traditional and popular type of compressor in civil applications. Structure of piston compressor relatively simple, making it easy to repair and maintain.
Working principle of piston compressor based on the up and down movement of the piston in the cylinder. When the piston moves up, the pressure inside the cylinder increases, pushing the cold air out. Conversely, when the piston moves down, the cold air will be sucked into the cylinder. Piston compressors are quite efficient in small and medium capacities but have high noise and low efficiency in large capacities.
The biggest advantage of piston compressors is their low cost and ease of maintenance. This is also the reason why piston compressors are widely used in household appliances such as refrigerators and small air conditioners.
Scroll compressor
Scroll compressor is one of the modern compressors, used in many modern refrigeration systems. The structure of the scroll compressor includes two spirals, one fixed spiral and one rotating spiral.
Working principle of scroll compressor very unique, when a rotating spiral sucks and compresses cold air between the gaps of two spirals. The cold air will be gradually compressed and pushed out of the compressor with high pressure. This helps the spiral compressor operate smoothly and with little vibration.
However, scroll compressor are more expensive than piston compressors and are often difficult to repair and maintain. However, high efficiency and long life make scroll compressors the first choice for many refrigeration systems.
Rotary compressor
Rotary compressor is a type of compressor with a simple design but brings high working efficiency. The design of this compressor uses a rotating rotor to suck and compress cold air.
Working principle of rotary compressor based on the change in volume in the compression chamber as the rotor rotates. The cold air is sucked in and compressed, then pushed out at high pressure. One of the great advantages of rotary compressors is their compact size and quiet operation.
Although the cost of rotary compressor relatively high, but with good working performance and low maintenance requirements, it is still widely used in appliances such as air conditioners and refrigerators.
Centrifugal compressor
Centrifugal compressor is a specialized compressor for large industrial applications. With complex design and high cost, centrifugal compressors are often used in large-scale refrigeration systems, such as in factories and commercial centers.
Working principle of centrifugal compressor based on the centrifugal force generated when the impeller rotates at high speed. Cold air is sucked in and pushed out from the center of the impeller, and is compressed. One of the biggest advantages of centrifugal compressors is the ability to achieve high power and high efficiency in industrial applications.
However, centrifugal compressor However, with its superior performance and reliable operation, centrifugal compressors are still a good choice for many large refrigeration systems.
