A compressor cycle is the first step in the compression process. The compressor’s speed is affected by a number of factors, such as the size of the compressors’ coils, the flow rates of the compressed air and gas, the flow rate of the refrigerant gases and the temperature of the compressor. It is essential that these parameters are chosen in such a way that they are capable of reducing the compression time, while at the same time allowing for the maximum efficiency. The most important factor is the compression ratio.
Compressor cycles have been defined as the steps which comprise the compression process and also the number of times that a compressor turns on and off at one go. There are three basic compressor cycles and the compressor cycles used for different purposes and for various applications are different. For instance, the compressor cycle used for compressors to provide high pressure, is known as the primary cycle. This cycle operates at very high power as it compresses the main gas for which it is employed, then as it becomes less dense, it is forced to turn off.
The next compressor cycles is called the secondary cycle. This cycle starts by compressing the gas which is in storage when the compressor is switched off. Then this gas is re-circulated with high pressure so that it has the ability to turn on again after which it is again compressed. These cycles are useful in situations where there is a significant power requirement for the compressors. They can be operated on a lower pressure level, but there is a risk of over compression leading to damage to the compressor and also the safety of the compressor, so it is not advisable to use them at such a low level.
