AI Technical Summary

Benefits of technology

The patent text describes a method to increase the efficiency of air compression by cooling the atmosphere air before it enters the compression process using the cooled compressed air from the previous process. The method also involves heating the outgoing stream from the compression process using residual heat from an after-cooler that receives the compressed air. The cooling and heating processes lead to an increase in efficiency of the compression process in about 7-9%.

Problems solved by technology

The efficiency of producing compressed air is very low.
As rotation advances, a lobe on one screw rolls into a groove on the other screw and the point of intermeshing moves progressively along the axial length of the screws, reducing the space occupied by the air, resulting in increased pressure.

Embodiment Construction

[0043]Before explaining at least one embodiment of the disclosed subject matter in detail, it is to be understood that the disclosed subject matter is not limited in its application to the details of construction and the arrangement of the components set forth in the following description or illustrated in the drawings. The disclosed subject matter is capable of other embodiments or of being practiced or carried out in various ways. Also, it is to be understood that the phraseology and terminology employed herein is for the purpose of description and should not be regarded as limiting. The drawings are generally not to scale. For clarity, non-essential elements were omitted from some of the drawings.

[0044]One technical problem dealt with by the disclosed subject matter is the low efficiency of generating compressed air by commercially available air compressors. The efficiency of compressed air production can be calculated by a ratio between the energy in the compressed air and the e...

Abstract

The present disclosed subject matter relates to energy efficiency improvements in compressed air systems and methods to implement them. According to an aspect of the present disclosure, improving the efficiency is performed by recovering the “wasted energy” in the compressed air and / or condensed water energy streams produced by the compressor and the cooling drying process.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This patent application is a Continuation-in-Part of the U.S. National Phase of PCT Patent Application No. PCT / IB2019 / 059946, filed Nov. 19, 2019, which is based upon and claims the priority of U.S. Provisional Patent Application Ser. No. 62 / 769,580, filed Nov. 20, 2018, and claims priority also from U.S. Provisional Patent Application Ser. No. 63 / 026,773, filed May 19, 2020, each of which is incorporated herein by reference in their entirety.TECHNICAL FIELD[0002]The present subject matter relates to compressed air systems. More particularly, the presently disclosed subject matter relates to systems and methods of using waste heat in compressed systems, thus, improving the systems' efficiency.BACKGROUND[0003]According to CAGI (Compressed Air & Gas Institute), compressed air in industry is often referred to as the fourth utility after electricity, natural gas, and water. Compressed air is the energy of choice. It is used widely throughout ...
