Performance des systèmes frigorifiques avec échangeurs de chaleur à aspiration liquide.

Refrigeration system performance using liquid-suction heat exchangers.

Auteurs : KLEIN S. A., REINDL D. T., BROWNELL K. A.

Résumé

Heat transfer devices are provided in many refrigeration systems to exchange energy between the cool gaseous refrigerant leaving the evaporator and warm liquid refrigerant exiting the condenser. These liquid-suction or suction-line heat exchangers can, in some cases, yield improved system performance while in other cases they degrade system performance. Although previous researchers have investigated performance of liquid-suction heat exchangers, the study can be distinguished from the previous studies (new correlations, new refrigerants, impact of pressure drop). Reliance on simplified analysis techniques leads to inaccurate conclusions regarding the refrigeration system performance impacts of liquid-suction heat exchangers. From detailed analyses, it can be concluded that liquid-suction heat exchangers that impose minimal low-side pressures are useful for systems using R507A, R134a, R12, R404A, R290, R407, R600, and R410A refrigerants. The liquid-suction heat exchanger is detrimental to system performance in systems using R22, R32, and R717 refrigerants.
