In recent years, with the increase awareness towards environmental degradation due to the production, use and disposal of ChloroFluoro Carbons (CFCs) and Hydro Chlorofluorocarbons (HCFCs) as heat carrier fluids in conventional refrigeration and air conditioning systems has become a subject of great concern and resulted in extensive research into development of novel refrigeration and space cond...

Design and developmental methodology of thermoelectric refrigeration has been explained in detail also the theoretical physical characteristics of thermoelectric cooling module used in this research work have been investigated. Authors have been designed and developed an experimental prototype of thermoelectric refrigeration system working on solar photo voltaic cells generated DC voltage. The ...

 liquefied natural gas (LNG) is the most economical way of transporting natural gas (NG) over long distances. Liquefaction of NG by using vapor compression refrigeration system requires high operating and capital cost. Due to lack of systematic design methods for multistage refrigeration cycles, the conventional approaches of determining optimal cycle configuration are mostly based on trial-an...

The paper mainly deals with the match of solar refrigeration, i.e., solar/natural gas-driven absorption chiller (SNGDAC), solar vapor compression–absorption integrated refrigeration system with parallel configuration (SVCAIRSPC), and solar absorption-subcooled compression hybrid cooling system (SASCHCS), and building cooling based on the exergoeconomics. Three types of building cooling are cons...

This article presents the magnetic refrigeration technology that is based on magnetocaloric effect, heating or cooling of a material when applied field changes. The first part paper shows an introductory study evolution this over years, continuing with presentation regenerator model, which composed two heat exchangers parallel plates material, gadolinium and are separated by transfer agent flow...

Direct expansion (DX) refrigeration technology is almost exclusively used in multi-temperature transport refrigeration systems. Multi-temperature systems use up to three evaporators, requiring large refrigerant charges and system pressure control to operate over a wide range of set-point conditions. Despite incremental design improvements over the past decade, environmental and control issues c...

A small refrigeration plant, for teaching refrigeration theory, used a control console built to traditional design guidelines: one output in the display for each sensor in the plant. This style of console is notorious for inducing high cognitive loads on operators and for displaying redundant data. Often the high cognitive load is the result of inconsistency between the intent for displaying th...

Simultaneous production of fresh water and refrigeration are often required, e.g. in warm-climate waterdeficient regions, and this study is a proposal and analysis of an efficient way of producing both of them by consuming mainly low-grade heat. After introducing the configuration choice methodology, a combined refrigeration and water system, ARHP–MEE (absorption refrigeration heat pump and mul...

In the present study, the ice slurry refrigeration system with pre-cooling heat exchanger (ISSH) is studied experimentally to achieve the system performance, ice crystal formation time and the temperature of ice crystal formation. The operating parameters considered in this paper include the concentration of salt solution, suction pressure, discharge pressure and Energy Efficiency Ratio (EER). ...
