Car Air Compressor concepts and classifications

>

Vehicle Air Compressor is the core component of air-conditioning method, its operate is exterior guide to keep the refrigerant in the refrigeration cycle technique, inhaled from the evaporator lower temperature, low stress refrigerant vapor, compressing the refrigerant vapor temperature and strain rise to and refrigerant vapor sent to the condenser, the warmth absorption and release procedure, to accomplish heat trade. Compressor in the refrigeration routine, compression and pumping play the role of refrigerant, the refrigeration technique is the "coronary heart."

According to the completely different operates, can be divided into fixed and variable displacement compressor displacement compressor. Fixed displacement compressor displacement is elevated as the engine pace in proportion to the expand, it can not instantly according to variations in the demand for cooling strength output, and the influence on engine fuel consumption is reasonably large. Variable displacement compressor to immediately modify the temperature according to the set strength output.
In accordance to the various options of doing work, can usually be divided into reciprocating compressors and rotary, reciprocating compressors have a standard crankshaft connecting rod and the axial piston rotary compressor with a prevalent rotary vane and scroll.
Compressor crankshaft connecting rod is the first of all an individual on behalf of the compressor, it is utilized a great deal more commonly, manufacturing solutions is mature, effortless structure, but also for processing supplies and very low processing standards, the value is relatively small. Adaptability, capable to adapt to a extensive vary of stress and cooling potential standards, servicing of good, very good reliability. But the crankshaft connecting rod compressor also has some evident shortcomings, such as the inability to achieve significant velocity, sizeable and hefty machinery is not very easy to acquire lightweight. Exhaust is not steady, straightforward movement fluctuations, and the greater the vibration at give good results. Now especially handful of smaller displacement compressor utilizing this framework, the crankshaft connecting rod compressor now exists only in the bus and truck air conditioning units, but also by huge displacement ten-cylinder swashplate compressor changed trend.
Axial piston compressor can be referred to as Generation 2 compressors, a widespread rock or swashplate compressor disc. These types of has been the Auto Air Compressor top item, accounting for 70% of all the compressor, as the technologies progresses, the axial compressor can not only be a small light excess fat, and optimum speed of up to ten,000 r / min or even more. In particular the axial compressor 1st to realize the stepless variable displacement regulate, specially by the auto makers of all ages.
Compact rotary compressor, large efficiency, increased pace as the most important attributes. Between them, the rotary vane compressor is the third era compressor, its quantity and excess weight can be incredibly modest, straightforward-to-be in the narrow layout of the motor compartment, coupled with the volume of noise and vibration, and increased effectiveness in the automotive air conditioning system has also been a particular application. But the rotary vane compressor for elevated precision machining, manufacturing costs are increased.
Scroll compressor can be termed the 4th era of the compressor. Scroll compressor, compared with the conventional compressor, displacement scenarios in the equivalent segment of product, energy preserving is really higher. As a result of of its minimal dimension, light excess weight, lower noise, no valves, spare sections, long living, huge volume performance, beneficial operation and affordable electric power usage, it can energy down 10%, 40% reduction in quantity, bodyweight down 15%. Also is incredibly resistant to fluid strike, the oil strike, cooling speed, starting off torque, lower noise, elevated reliability and a variety of plus points. Refrigeration marketplace in common that the scroll compressor is the greatest Auto Air Compressor.
