In a steam-pressure units, the most important element in the compressor. The most important part of the VC unit also the most expensive part. There are different types of compressors. The guy that used in refrigeration unit is divided into two groups. The groups are; displacement and rotor dynamics.
The positive displacement type of compressor works by trapping the refrigerant vapor in a closed room and then turn down the volume. ThisThis increases the pressure and the volume is reduced because it is a steady amount of refrigerant that any time is caught. Two examples of a positive displacement compressor is a piston or a piston compressor. They are used the most widely used PDC. It can be found in areas in the high HP from very little horsepower. Piston compressors work in kind of the same way as a combustion engine. Besides it works inconversely, they have cylinders, pistons, crankshafts, valves, and blocks.
The rotor-dynamic nature of the compressor to increase the pressure that the refrigerant is provided by increasing the kinetic energy to an ever-flowing stream. He does this with a rotating mechanical element and then the conversion of refrigerant in pressure as it flows through a divided body. The rotor-dynamic compressors have less vibration because they have a steady stream. There are severalTypes of RDC. The first is radial flow. This type of compressor used in large refrigeration units and air conditioners. The rotor-dynamic compressors have less vibration because they have a steady stream. The second is axial flow. This type is often used in gas liquefaction appliance.
Depending on the alignment of the motor or external dive, it can either be an open, hermetically sealed, or if a semi-hermetic partially closed.The open type is more efficient and it has better flexibility, and also better compressor cooling and service capabilities. Due to the rod having to extend through the seal, you can not completely stop the leaking of refrigerant.
With the hermetic type it is surrounded by a box so you do not get any leaking. It works best in units that capillary tubes for expansion mechanism and are critically charged systems. They do not leak but you can not service this type. Also it is not very Flexible It is very difficult to change the speed of cooling. This species is frequently used in small refrigerators, air conditioners and water coolers. This type is what is used in your home.
The last is the semi-hermetic. This type works just like a hermetic manner, with the exception of the frame around the unit so it is easier to manage. Because it is easier to get to.
