TESTING METHODOLOGY OF ONE-STAGE AND MULTI-STAGE COOLING CIRCUITS IN COOLING INSTALLATIONS.

[In Polish. / En polonais.]

Author(s) : CHLOPECKI A.

Type of article: Article

Summary

THE ARTICLE PRESENTS A NEW THEORY OF THE EFFICIENCY OF REFRIGERATION AND OTHER CYCLES, RESULTING FROM THE FIRST AND THE SECOND PRINCIPLE OF THERMODYNAMICS. ACCOUNT HAS BEEN TAKEN OF THE FACT THAT THE WORK OF A REFRIGERATING UNIT IS BASED ON THE TRANSFER OF THERMAL ENERGY FROM A LOWER TEMPERATURE LEVEL TO A HIGHER ONE. THE REDUCED TEMPERATURE DIFFERENCE HAS BEEN ASSUMED AS THE WAY OF THE THERMAL ENERGY TRANSFER. THE NUMERICAL VALUES OF REFRIGERATION CYCLE EFFICIENCY CONNECTED WITH THE THEORY ARE ALWAYS INCLUDED WITHIN THE RANGE OF ZERO TO ONE. AN ANALYSIS WAS ALSO MADE OF SINGLE-AND MULTI-DEGREE REFRIGERATION CYCLE EFFICIENCIES, HEAT PUMP CYCLES AND REFRIGERATING-HEATING CYCLES. THE EQUATIONS AND VALUES WERE COMPARED WITH THE PRESENTLY APPLIED MAGNITUDES, AND ALSO WITH THE EXERGY WHICH RESULTS FROM THE SECOND PRINCIPLE OF THERMODYNAMICS.
