EXERGETIC ANALYSIS OF A VAPOR INJECTION COMPRESSION HEAT PUMP
Abstract
The paper presents an exergy analysis of a heat pump with a steam injection. Different refrigerants as R290, R152A and R1234yf are considered. Constructive schemes such as two-stage heat pumps or cascade couplings are known and used to reduce the temperature at the compressor discharge level, but the presence of two or more compressors increases the cost of the initial investment of the equipment. This paper presents the design of a steam injection heat pump that has the advantage of a simple construction and can be applied in a wide range. For each apparatus, corresponding to its utility and operating field, the exergetic balance states the -product- and -fuel-. The work analyzes the conduct of the system at the variation of the operating and constructive parameters. The exergetic technique succeeds in pointing out for every dissipative zone the exergy destruction and losses.
