The Compressor Start / Stall / Knocking Noise Test System (CSTS) is a specialized platform designed to evaluate the dynamic behavior of compressors during the most critical operating moments: start-up, stalling events, and knocking noise occurrences. These characteristics are essential for defining compressor quality, reliability, and acoustic performance, especially in modern, efficient refrigeration and heating systems.
The CSTS accommodates a wide range of compressor applications:
- Standard fixed-speed compressors driven by induction motors
- Variable capacity compressors, including brushless DC (BLDC) models
- Compatible with a variety of inverters
This flexibility makes the system ideal for engineering, R&D, and quality verification across diverse compressor platforms.
The CSTS can automatically perform:
- Start tests
- Stall detection and stall behavior characterization
- Knocking noise measurements
The CSTS exposes compressors to a large and precisely controlled range of parameters:
- Suction pressure
- Discharge pressure
- Suction gas temperature
- Ambient temperature
- Supply voltage
- Compressor winding temperature
