Hunting phenomena of automotive air conditioning systems with variable displacement compressors.

Author(s) : DOU C., TIAN C., YANG X., et al.

Summary

Automotive air conditioning (AAC) systems with a variable displacement compressor (VDC) tend to experience hunting problems in which the system undergoes oscillation. The purpose of the paper is to study the hunting phenomena in this system and to elucidate the factors causing system stability by experimental investigation. In the paper, the test bench and testing method are described and four kinds of hunting phenomena summarized from the authors' experiments are introduced in detail, i.e. hunting in the evaporator and thermal expansion valve (TEV) control loop, hunting in the AAC system with a VDC and fixed-area throttling device, hunting in the AAC system with a AAC and TEV, and hunting in an ungoverned AAC system.
