Benchmark refrigeration systems in the road transportation sector are powered by diesel, having operation costs of up to 6,000 €/y with the consequent increase of the goods cost. This chapter presents an alternative refrigeration system based on fuel cells (FC) and hydrogen as fuel, with higher efficiency, reduced costs and independent of diesel price fluctuations. Examples of the energy load p...

Gas turbine inlet air-cooling (TIAC) is an established technology for augmenting gas output and efficiency, especially in hot regions. TIAC using evaporative cooling suitable hot, dry regions; however, the limited by ambient wet-bulb temperature. This study investigates two-stage under harsh weather of Riyadh city. The system consists indirect direct stages. In stage, air precooled water cooled...

Despite continual development over more than two centuries there is still great scope for significant in the realms of mechanical cooling and heating. This paper reviews nature historical identifies key motivations technical development. It seeks to highlight where greatest need future this ubiquitous technology. The story refrigeration dominated by choices made with regard working fluid used s...

The energy consumption by heating, ventilation, air conditioning, and refrigeration systems forms a large portion of the total energy usage in buildings. Vehicle fuel consumption and emissions are also significantly affected by air conditioning. Air conditioning is also a critical system for hybrid electric vehicles and electric vehicles as the second most energy consuming system after the elec...

Low temperature process cooling is an energy demanding part in many chemical production processes. Cooling systems operating at very low temperatures consume a large amount of high quality energy such as electricity or high pressure steam, used to drive refrigeration compressor units. Hence decreasing refrigeration load can make a major improvement on the process energy balance. In industrial p...

This paper provides a brief summary of current solar cooling technologies based on a literature review of 16 journal articles. The REDD facility at DRI currently uses two methods of cooling: an absorption chiller driven by solar thermal, and an evaporative cooler which can be run off of solar photovoltaic. This literature search is to identify what are the best technologies to convert solar ene...

This paper examines through a thermodynamic analysis the feasibility of using waste heat from marine Diesel engines to drive an ammonia-water absorption refrigeration system. An energy balance of a diesel engine shows that sufficient waste heat is provided. The results illustrate that higher performance of the system is obtained at high generator and evaporator temperatures and also at low cond...

The majority of integrated energy systems (IES) for combined electricity, heat and refrigeration generation, or trigeneration, are based on gas engines. fuel efficiency engines strictly influenced by intake air temperatures. Practically in all IES the absorption lithium-bromide chillers (ACh) applied conversing removed from engine into form chilled water. peculiarity trigeneration food industri...
