Description

Technical Field

[0001] This utility model relates to the field of refrigeration unit technology, specifically a low-noise, high-stability scroll refrigeration unit. Background Technology

[0002] Scroll compressor units are highly efficient and energy-saving refrigeration equipment, with a scroll compressor as its core component. The scroll compressor uses two meshing scroll discs that rotate to form a series of closed crescent-shaped cavities. As the scroll discs rotate, these cavities continuously move towards the center and decrease in volume, thus compressing the gas. Scroll compressor units are widely used in air conditioning, refrigeration, and cold storage due to their compact structure, stable operation, low noise, and high energy efficiency. With the increasing demands for quality of life, the need for refrigeration equipment is also growing, especially in large-scale commercial refrigeration systems requiring long-term stable operation, where the importance of scroll compressor units is becoming increasingly prominent.

[0003] Despite the numerous advantages of scroll chiller units, traditional technology still has some shortcomings. Firstly, during operation, the friction and wear between the scroll plates of a traditional scroll compressor generate noise and vibration, which not only affects the equipment's lifespan but may also disturb the surrounding environment. Secondly, the stability of traditional refrigeration systems needs improvement, especially under extreme weather conditions and complex operating environments, where system stability and energy efficiency may be affected. Furthermore, refrigerant leakage in traditional refrigeration technology cannot be ignored, as it not only damages the ozone layer but also poses potential threats to human health and the environment. Therefore, overcoming the shortcomings of traditional scroll refrigeration technology, improving equipment stability and energy efficiency, reducing noise and vibration, and preventing refrigerant leakage have become urgent problems to be solved in the field of refrigeration technology. To address these issues, we propose a low-noise, high-stability scroll chiller unit. Utility Model Content

[0034] Working Principle: First, the compressor 4, in conjunction with the receiver 2 and evaporator 5, establishes the initial power mode for refrigerant circulation. The compressor 4, located on the fixed plate 3, extends its bottom output end to the top of the inner wall of the receiver 2, drawing in and pressurizing liquid refrigerant. The pressurized refrigerant is then transported to the evaporator 5 via the connecting pipe 7. In the evaporator 5, the refrigerant absorbs external heat and evaporates, achieving initial cooling. During this process, the continuous operation of the compressor 4 provides the necessary power for the entire refrigeration cycle. Then, the second evaporator 6, in conjunction with the second connecting pipe 8 and the receiver 2, forms a refrigerant diversion refrigeration mode. After some refrigerant evaporates in the evaporator 5, the remaining portion flows back to the receiver 2 via the second connecting pipe 8, preparing for the next cycle. Simultaneously, the second evaporator 6, acting as another cooling point, receives refrigerant from the second condenser 10 via the fifth connecting pipe 14, further distributing the cooling load and improving overall cooling efficiency. The condenser 9, in conjunction with the second condenser 10, via the third connecting pipe 11 and the fourth connecting pipe 12, achieves a refrigerant condensation and reflux mode. The refrigerant evaporated in evaporator 5 and the second evaporator 6 enters condenser 9 and the second condenser 10 through the sixth connecting pipe 15 and the fifth connecting pipe 14, respectively. In the condenser, the refrigerant releases heat and condenses into a liquid state, then flows back to the liquid receiver 2 through the third connecting pipe 11 and the fourth connecting pipe 12, completing the refrigerant recycling. Cooling fans 13 link condenser 9 and the second condenser 10 to enhance heat dissipation. Cooling fans 13 are installed at the top of condenser 9 and the second condenser 10 to accelerate airflow, effectively removing heat from the condensers and ensuring efficient refrigerant condensation, maintaining stable operation of the refrigeration system. The pressure controller 16 and pressure sensor 17 link the third connecting pipe 11 and the fourth connecting pipe 12 to achieve system pressure monitoring and regulation. The pressure sensor 17 monitors the refrigerant pressure in the fourth connecting pipe 12 in real time and feeds the signal back to the pressure controller 16. When the pressure is abnormal, the pressure controller 16 automatically adjusts the refrigerant flow or activates a protection mechanism to ensure the refrigeration system operates under safe and stable pressure, reducing noise and enhancing stability.
