6 FAQs about [Theoretical design of screw air compressor]

What is the scientific basis of a screw compressor?

Despite the rapid growth in screw compressor usage, the scientific basis of their design is still limited. Several screw compressor textbooks were published in Russia in the early nineteen sixties. Sakun 1960 gives a full analysis on rotor profiles based on the envelope method.

What is a screw compressor design process?

As other design processes, the design of screw compressors is an interactive feedback process where the performance of the compressor is compared with those specified in advance. Usually this is a manual process where the designer makes a prototype system which is tested and modified until it is satisfactory.

What is a twin screw air compressor?

The twin screw air compressor is a positive displacement compressor and has been widely used in gas industries. One of the major advantages of the twin screw compressor is its flexibility under various operation conditions. It utilizes the continual variations of the space formed between rotor grooves and case of the compressor.

Can a computer model be used for screw compressor optimisation?

In order to make such computer models more readily accessible to designers and engineers, as well as specialists, the authors have developed a suite of subroutines for the purpose of screw machine design, Hanjalic and Stosic, 1997, which duly can be used in screw compressor optimisation.

Why is screw compressor used in refrigeration & air conditioning industry?

ABSTRACT The screw compressor is widely used in refrigeration and air conditioning industry due to it high efficiency. The screw compressor are said to have an efficiency of about 75% to 80%. The one percent of efficiency of the screw compressor is lost due to some of the losses which restrict it from being 100% efficient.
