The potential to store energy within refrigerated food products presents convenience store and supermarket operators with an opportunity to participate in utility sponsored demand response programs, whereby electricity usage can be shifted or reduced during peak periods. To determine the feasibility of reducing peak demand by shifting the refrigeration load to off-peak times, experimental and a...

Centrifugal compressors are most widely used in large capacity refrigeration and air conditioning plants. Its other applications include in gas turbines for air craft applications, diesel engine turbochargers, chemical and process industries, factory workshop air supplies etc. In refrigeration field these are suitable for high specific volume refrigerants or low pressure stages. They have been ...

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...

A cold storage room for Umudike has been designed to provide a better storage facility for perishable food stuff in the community and to promote the living standard of the people. It is an adaptive design aimed at designing the cold room to suit the prevailing factors of Umudike community with reference to some design calculations. This is timely, and a first of its kind within the locality. Th...

Adsorption refrigeration, being a unique and eco-friendly technology, has gained popularity over conventional refrigeration systems. The present study is aimed at developing an annular finned tube adsorber model which serves as thermal compressor in adsorption mathematical addressed numerically using finite difference discretization method explicit scheme was used for the solution. generalized ...

 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...

Compressed air energy storage (CAES) is increasingly investigated as a viable technology for balancing electricity supply and demand. The main purpose of CAES to overcome the intermittent problem when renewable introduced. However, round-trip efficiency (RTE) system commercially developed still low (around 54 %) requires further improvement. This study proposed novel combined cooling, heating p...
