Introduction to Scroll Compressors

Renowned for their high energy efficiency, exceptional reliability, and low vibration levels, scroll compressors have found widespread application in fields such as high-temperature heat pump drying, air-conditioning chillers, and medium-to-low temperature refrigeration and freezing systems. Adhering to a product philosophy of "striving for precision over novelty, and substance over superficiality," Suzhou Weishans Climate Technologies Co., Ltd. focuses exclusively on the design, R&D, manufacturing, and sales of scroll compressors.

Structure of the Scroll Compressor

A scroll compressor primarily consists of a scroll assembly (comprising a orbiting scroll and a fixed scroll), bearings (main and bottom bearings), a rotor assembly, an eccentric shaft, and various other components. The typical structure of a scroll compressor is illustrated in the diagram below:

Working Principle of the Scroll Compressor

The compression mechanism of a scroll compressor is composed of an orbiting scroll and a fixed scroll, which together form crescent-shaped compression chambers. Low-temperature, low-pressure gas enters the compressor through the suction port. During the compression process, the fixed scroll remains stationary, while the orbiting scroll—driven by the rotor via the eccentric shaft and constrained by an anti-rotation mechanism (such as a Oldham coupling)—executes a planar orbital motion. Consequently, the gas within the compression chambers is compressed into high-temperature, high-pressure gas, which is then discharged through the exhaust port located at the center of the scroll assembly.

The fundamental working principle of a scroll compressor relies on the relative orbital motion between the orbiting scroll and the fixed scroll to create a continuous variation in enclosed volume, thereby achieving the objective of gas compression.

Technical Advantages of Scroll Compressors

Leveraging their unique structural design, scroll compressors demonstrate significant technical advantages across the fields of heat pumps, refrigeration, and air conditioning. Their core advantages include:

1.  **Simple and Compact Structure:** Characterized by a small footprint, light weight, high reliability, high efficiency, and a long service life.

2.  **Flexible Design:** Incorporates a flexible structure that provides strong resistance to impurities and liquid slugging.

3.  **Smooth and Stable Operation:** Features low rotational inertia forces, excellent dynamic balance, minimal overall vibration, and exceptionally smooth running performance.
