Sažetak
For many years, CIAT, a French manufacturer of refrigeration and air conditioning material, has been working for setting up the solutions for the real protection of environment. The R&D Teams analyse the new refrigerants well adapted to their applications : R134a, R404A, R407C, Isceons, NH3,
In this paper the last results of experiments conducted by CIATs Research Laboratory in France are presented. It deals with the comparison between plates and shell and tubes heat exchangers performances operating with R22 and R407C as well as chillers behaviour analysis during five years period.*
This study is related to CIAT chillers fitted with EXEL brazed plate exchangers and TUBULAR heat exchangers working with reciprocating compressors, initially operating with R 22 and ester oil, then with R 407C. Several parameters of the installation were compared including cooling capacity, heating capacity, absorbed power, energy efficiency ratio as well as the variation in the composition and miscibility of the oil.
To assess the life-cycle and reliability of the chiller, the LCA and FMEA methods were applied. Further more the high accelerated life-tests HALT will be performed.
The results of these investigations are of significant importance for users and manufacturers of refrigeration installations operating with R407C.
