Introduction

Fangcheng Guo is an inventor associated with Foshan, China. His patent work addresses compressor control in refrigeration and air-conditioning systems, with a focus on estimating exhaust pressure from operating parameters.

Latest Patents

Guo is named on 1 patent: “Control Method, Apparatus, and Device for Compressor, Storage Medium, and Refrigeration System.” The invention describes obtaining the compressor’s electrical parameters, return-air parameters, and operating frequency, then using a frequency-specific fitting formula to calculate exhaust pressure. The compressor is controlled based on that estimate. This approach can eliminate the need for an exhaust-side pressure sensor or provide an alternative way to determine pressure when a sensor is present, potentially reducing costs while supporting normal system operation.
