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 ...

This paper investigates the interaction between supermarket heating, ventilation and air conditioning and refrigeration systems through simulation in EnergyPlus. This interaction has been studied by modelling a generic UK supermarket. The impact on the sum of HVAC and refrigeration energy consumption due to changes in a range of operating conditions was studied. These include the effect of alte...

Solar energy is the most abundant source of energy available in our country. The power of the sun can be efficiently used to harness energy for solving our energy needs. The void of not having efficient technology to tap this abundant energy reservoir has led to search for better technologies and more varied applications. Our primary focus in this paper would be on utilizing solar energy for do...

The purpose of this study is to numerically investigate the performance a solar physical surface absorption cooling system, in which activated carbon/methanol used as working pair, placed inside parabolic-shaped collector. governing mathematical model issue based on equations conservation mass, energy, and thermodynamics process. are discretized using fully implicit finite difference method, Fo...

Based on the model-free adaptive control (MFAC) theory, temperature tracking problem of single-effect LiBr/H2O absorption chiller is explored. Due to complex nonlinearity and strong coupling characteristics refrigeration system, strategy designed for its control. Nevertheless, traditional has a slow speed poor denoising ability. In order improve effect, output error rate added objective functio...

A refrigeration system which was originally designed using R502 as refrigerant was rebuilt to adapt the special requirements of R404A. The experiments, both for R502 and R404A, on this system were done and some parameters such as evaporating temperature, condensing temperature, discharge temperature, compressor input power and so on were measured under different working conditions. Then the ope...
