The Lobe type air compressor is very simpler type with no complicated moving parts.
The refrigerant entering the compressor must be in the gaseous state, as liquids are notoriously incompressible. The latter condenses and returns to the liquid state, while the outside air will be heated. An expansion device is thus needed to expand typrs liquid refrigerant and reduce its pressure to the value at which evaporation occurs. The rotary compressors are divided into Screw compressors, Vane type compressors, Lobe and scroll compressors and other types.
In my next article, air compressor types pdf download other types of compressors involving air compressor types pdf download and axial compressors will be discussed along with the other types of compressors classified on the basis of cooling mehtods, number of stages etc.
The rotary compressors are classified into screw type, vane type-lobe type, scroll type and other types.
Types of Air Compressors: Reciprocating, Rotary, Screw, Vane, Lobe
Service Pressure Low, Medium, High The Attached picture shows the clear classification of different types of compressors. Thus if one of the lobes is in horizontal position, the other at that particular instant will be in vertical position. These compressors are not of reciprocating nature, therefore does not have any pistons and crankshaft.
Temperature, humidity and pressure control solutions Speed pdff and inverters Powersolutions Obsolete products. Everything Products Documents Information. There are single or twin lobes attached to the drive shaft driven by the prime mover. Thus the compressed air is delivered through the central space of the scroll to the delivery air line. Tpes, the compressor has the function of circulating refrigerant inside the circuit, drawing it in as air compressor types pdf download gas from the evaporator and then compressing it air compressor types pdf download delivering it at higher pressure to the condenser.
These are usually air cooled compressors with concentric valves mounted on each cylinder head unit.
Thus there are so many types of air compressors used specifically for the above purposes. Do you aif more informations? Job and careers Legal notice. Thus both sides of the pistons are effectively used in compressing the air.
The air is compressed only on the top part of the piston.
Types of Air 01 | Gas Compressor | Pump
Not all air-conditioning and refrigeration applications have the same requirements in terms of capacity, noise, efficiency and operating range, and as a result there are different types of compressor. These are simple in design with almost very air compressor types pdf download automation. Refer the attached diagram of the reciprocating in-line compressors. These are usually reciprocating compressors, which has piston working on air only in one direction.
Under the Roto-dynamic compressors, we have.
These essentially differ as regards the way compression is achieved, with reciprocating compressors featuring a reciprocating movement to create compression, and rotary compressors, including rotary vane, scroll, screw and centrifugal compressorsfeaturing a rotational movement to bring about compression.
The scrolls outer edges trap air and then as they rotate, the air travel from outwards to inwards thus getting compressed due to the reduction in the area. These are most commonly air compressor types pdf download compressors with varying pressure ranges.
Types of compressors
The screw compressors are efficient compressor low air pressure requirements. Better torque and balancing is achieved by displacing the units by certain angle. Read here to get the total insight about the different types of compressors and their pictures.
The cylinders of various stages air compressor types pdf download found in a straight line when seen from top.
Single-acting compressors, Double-acting compressors, Diaphragm compressors. The bottom of copmressor piston is open to crankcase and not utilized for the compression of air. Types of Air Compressors: Thus the compresssor plates moves away from the center, huge quantities of air will be trapped in, thus as the plates converge, the air gets compressed and thus results in compressed air.
As the piston moves up and down, both sides of the piston is utilized in compressing air compressor types pdf download air.
Compressor power consumption depends on the difference between the two operating pressures. Read here to know about the common reciprocating compressor and very recent development in vane and lobe type compressors.
The Vane type Air Compressor is having a fixed casing and a pdc rotor disc which has slots for holding the air compressor types pdf download plates as shown in the figure.
