The interest in application of secondary refiigerant systems in supermarket refrigeration is increasing. Reduced refrigerant losses i and the chance for lower installation and operation costs is promoting this development. There are also !options to use natural refrigerants, more efficient refrigerants and gas or waste heat driven absorption proc;esses. First installations of secondary refriger...

â 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...

In this study, a solar single/double-effect switching LiBr-H2O absorption refrigeration system was investigated to make full use of energy and give play the advantages systems. A corresponding thermodynamic dynamic mathematical model developed. The operation characteristics operating continuously for one week were analyzed. order highlight system, it compared with other forms systems compressio...

Climate change is the hottest topic today on earth. Traditional HVAC’s harm environment and stand out to be a major contributor global warming. One of many techniques mitigate current climate crisis by utilizing abundantly available solar radiation. Solar evacuated tube collectors are used absorb This power provide cooling technologies. Unlike conventional thermally driven absorption boon in to...
