Type of monograph: Doctoral thesis
Summary
This thesis was presented within the framework of obtaining a high-level refrigeration and air-conditioning technician's diploma. Summary of contents: description of the plant and identification of the problems to be solved; comparison of R22 and other refrigerants (environmental aspects; thermodynamic properties; safety; technical and economic aspects); comparison of R22 and R407C cycles (R22 and R407C operating cycles; table showing the characteristics of R22 and R407C cycles); consequences of retrofitting on plant components (consequences at the levels of the condenser, the evaporator, the compressor, the expansion valve, regulating and safety devices; retrofitting and post-retrofitting monitoring.
