Energy Efficiency Engineering

Description

The paper deals with a heat pump system for the food industry characterized by two products - refrigeration and heating. The working fluid is ammonia, an ecological refrigerant harmless for the environment. For every apparatus, corresponding to its utility and operating field, the exergetic balance states the “product” and “fuel”. The work analyses the conduct of the system at the variation of the operating and constructive parameters. The exergoeconomic technique succeeds in pointing out for every dissipative zone the exergy destruction and losses.

Keywords:

cogeneration heating and cooling, exergy analysis, exergy destruction, fuel and product

Exergetic Analysis of a Cogeneration System for Cooling and Heating

Pristina, Kosovo

The paper deals with a heat pump system for the food industry characterized by two products - refrigeration and heating. The working fluid is ammonia, an ecological refrigerant harmless for the environment. For every apparatus, corresponding to its utility and operating field, the exergetic balance states the “product” and “fuel”. The work analyses the conduct of the system at the variation of the operating and constructive parameters. The exergoeconomic technique succeeds in pointing out for every dissipative zone the exergy destruction and losses.
