The Bizelle piston air-cooled unit is an excellent refrigeration equipment, and its detailed introduction is as follows:

Structural composition

-Compressor:Adopting the Bizelle semi closed piston compressor, it has the advantages of good quality, reliable operation, high refrigeration efficiency, and long service life.

-Condenser:Usually, it is a copper tube aluminum sheet or shell and tube condenser with high heat transfer efficiency, which can quickly dissipate the heat of the refrigerant into the air. Among them, the copper tube is tightly expanded with the aluminum sheet to ensure good heat transfer performance; Shell and tube condensers have the characteristics of compact structure and high pressure resistance.

-Fan:External rotor condensing fans are commonly used, which have the advantages of low noise, high efficiency, and beautiful appearance, and can effectively dissipate the heat in the condenser.

-Other accessories:Select high-quality domestic or imported refrigeration components, such as expansion valves, drying filters, solenoid valves, sight glasses, oil separators, etc., with complete configurations to ensure the reliability and stability of the unit operation.

working principle

The compressor sucks in low-temperature and low-pressure refrigerant vapor from the evaporator, which is adiabatically compressed into high-temperature and high-pressure superheated vapor, and then pressed into the condenser for constant pressure cooling, releasing heat to the cooling medium and cooling into supercooled liquid refrigerant. The liquid refrigerant is adiabatically throttled by the expansion valve to become a low-pressure liquid refrigerant, which evaporates and absorbs heat in the evaporator, thereby achieving the purpose of refrigeration. The low-pressure refrigerant flowing out is sucked into the compressor and works in this cycle.

Performance characteristics

-Efficient and energy-saving:The energy efficiency ratio of the Bizelle compressor is high, and under the same cooling demand, the energy consumption is relatively low, which can reduce operating costs. Some units adopt a parallel design of multiple compressors, which can automatically adjust the number and load of compressors according to actual load requirements, further improving energy efficiency.

-Reliable operation:The Bizel semi closed piston compressor has fewer moving parts, a compact structure, smooth operation, and low vibration, reducing the probability of failure and extending the service life of the unit. At the same time, the automatic control valves, electronic control systems and other accessories of the unit are all made of international and domestic first-line brands to ensure stable and reliable operation of the unit.

-Wide applicability:The product series is complete and suitable for a wide temperature range, which can meet different refrigeration needs such as preservation, refrigeration, ice making, and frozen water. It is suitable for various working conditions such as high temperature, medium temperature, and low temperature, and can be widely used in various cold storage refrigeration equipment.

-Easy maintenance:The unit structure is relatively simple, and each component is easy to inspect, repair, and replace. Meanwhile, the installation of waterproof terminal junction boxes facilitates user wiring, reducing maintenance difficulty and costs.

application area

-Cold storage project:Widely used in cold storage of various scales, such as fresh-keeping, refrigeration, freezing, etc., it can be used to store fruits, vegetables, meat, seafood, dairy products and other foods, ensuring the freshness and quality of the food.

-Food processing:In the food processing industry, such as meat processing, fruit and vegetable processing, beverage production, etc., cold sources are provided for cooling, freezing, refrigeration and other links in the production process to ensure product quality and safety.

-Chemical and Pharmaceutical:In chemical production, providing a low-temperature environment for reaction vessels, storage tanks, etc. ensures the smooth progress of chemical reactions and stable storage of raw materials. In the pharmaceutical industry, processes such as refrigeration and freeze-drying are used to ensure the effectiveness and safety of drugs.

-Other fields:It can also be applied to scientific research experiments, electronic component production, large shopping malls, hotels and other places with strict temperature requirements, providing a stable low-temperature environment for them.
