Accelerated evaluation of capillary clogging in HFC air conditioners.

Author(s) : TAIRA S., OONUMA Y., YAMAKAWA K., YAJIMA R.

Summary

The paper focuses on the accelerated evaluation method of capillary clogging and the methods to prevent HFC air conditioners from clogging. The clogging phenomenon is divided into four stages. First, the sludge is produced inside a compressor. Then, it is conveyed by lubricant to the capillaries or expansion valves. After it is separated from the refrigerants, it is deposited on the inner surfaces. The acceleration test was carried out by increasing the lubricant temperature and the refrigerant flow with different lubricants and compressors.
