Comparison of Energy Efficiencies of Commercial Refrigeration Direct and Indirect Systems
نویسنده
چکیده
Centralized commercial refrigeration is becoming a sector where several technical options are competitive. These options are evaluated based on three major criterions: energy consumption, refrigerant emissions and initial cost. In supermarkets with machinery rooms, the competition is strong between previous centralized direct systems and new systems using heat transfer fluids. To achieve balanced comparisons between energy efficiency of these competitive techniques, measurements of direct expansion systems and of systems using monophase heat transfer fluids have been performed on site.

The Comparison of Direct and Indirect Optimization Techniques in Equilibrium Analysis of Multibody Dynamic Systems
The present paper describes a set of procedures for the solution of nonlinear static-equilibrium problems in the complex multibody mechanical systems. To find the equilibrium position of the system, five optimization techniques are used to minimize the total potential energy of the system. Comparisons are made between these techniques. A computer program is developed to evaluate the equality co...
متن کاملThe energy and exergy analysis of a novel cogeneration organic Rankine power and two-stage compression refrigeration cycle
The energy crisis in recent years has led to the use of thermodynamic cycles that work based on renewable energies. Low-temperature cycles—such as organic cycles—are suitable strategies for the application of renewable energies. The present study proposes a novel cycle through the integration of a two-stage compression refrigeration cycle with a combined Rankine power and ejector refrigerat...
متن کاملAn Evaluation of the Environmental Impact of Different Commercial Supermarket Refrigeration Systems Using Low Global Warming Potential Refrigerants
Commercial refrigeration systems consumed 1.21 Quads of primary energy in 2010 and are known to be a major source for refrigerant charge leakage into the environment. Thus, it is important to study the environmental impact of commercial supermarket refrigeration systems and improve their design to minimize any adverse impacts. The system's Life Cycle Climate Performance (LCCP) was presented as ...
