1. SIMULAÇÃO DE SISTEMAS DE REFRIGERAÇÃO EM SUPERMERCADOS / REFRIGERATION SYSTEMS SIMULATION IN SUPERMARKETS
A thermodynamic model was developed for the evaluation of energy consumption and environmental impact (LCCP and TEWI) of supermarket refrigeration systems operating in three different configurations (direct expansion, secondary fluid and cascade). The model simulates refrigeration systems operating with pure substances or a mixture (azeotropic or non-azeotro

2. AnÃlise experimental de sistemas de refrigeraÃÃo operando com R-290 e R-600a como fluidos refrigerantes alternativos
Refrigerants CFC (chlorofluorocarbons), as R-12, deplete the ozone layer which protects the surface of the earth, due to the presence of chlorine in their structure. The HCFC (hydrochlorofluorocarbons), as R-22, also have chlorine in their molecule and must be replaced as a refrigerant fluid. In Europe, brand new equipments are not produced with HCFC-22, sin

3. EVALUATION OF THE GAS LOAD INFLUENCE ON AN AUTOMOTIVE AIR CONDITIONING SYSTEM / AVALIAÇÃO DA INFLUÊNCIA DA CARGA DE GÁS EM UM SISTEMA DE CONDICIONAMENTO DE AR AUTOMOTIVO
The modern automotive technology reaches considerable progress`s in the mechanical aspect as in the functional, with these technological advances, the biggest progress was made in the structure of the automobiles and in the air conditioning systems. Considering the importance of the use of refrigerant, the present work is developed, because the refrigerant g
