Objective
DEVELOPMENT OF HIGH TEMPERATURE (>100 CELSIUS DEGREES) WORKING FLUID FOR INDUSTRIAL HEAT PUMP AND PARTICULARLY NON AZEOTROPIC MIXTURES. DEVELOPMENT OF HIGH TEMPERATURE INDUSTRIAL HEAT PUMP USING THE TYPE OF WORKING FLUIDS. STUDY OF INDUSTRIAL APPLICATIONS.
The development of a high temperature heat pump for industrial applications (> 100 C) and the identification of working fluids were studied. 3 mixtures, water and alcohol, chlorofluorohydrocarbons, and chlorofluorohydrocarbons and paraffinic hydrocarbons were selected and characterised. A prototype (10 to 50 kW) was built and its thermal behaviour identified (heat loss and heat exchanger efficiency).
The classical technology and the new technology using a nonazeotropic mixture were compared economically. The reduction of pay back time as a function of the temperature variation of the process streams (T) was found to be between 30% and 40% for T = 30 and between 10% and 15% for T = 20.
THE PROJECT IS SUBDIVIDED IN 3 STEPS :
1. EXAMINATION AND SELECTION OF MIXTURES :
A) INVESTIGATION OF THERMAL STABILITY
B) STUDY OF THE THERMODYNAMIC OF THE MIXTURE; EXPERIMENTAL MEASUREMENTS
C) APPRAISAL OF THE BENEFITS RESULTING OF THE USE OF MIXTURES.
2. EXPERIMENTAL TESTS :
A) HEAT TRANSFER STUDY
B) EXPERIMENTATION OF AN EXPERIMENTAL 10 KW HEAT PUMP LOOP.
3. STUDY OF COMPRESSORS :
A) TECHNOLOGICAL ANALYSIS AND STUDY OF THE RANGE
B)PRE-PROJECT FOR A COMPRESSOR, ECONOMIC ESTIMATION.
