The Capability to Make Ice from Sunlight Utilizing a New Absorption Unit of Nano-Coated Ammonia/Calcium Chloride

In southern Jordan, the ice machine was designed, produced, operated, and fully examined at Mutah University, a unique Nano-coated ammonium/calcium chloride absorption sun unit. Analytical and experimental assessments on the use of ammonia/calcium chloride absorption unit ice produced. The new study has decreased energy emission by the Nano ice-making company while enhancing Nano's ice machine's nuclear power compared to standard solar chiller absorption that is not used in the current research. Our case was the world's first research to examine the effect of a nanoparticle combination of paint on an absorption cooling system used to make ice by the sunlight. The result of the test was quite encouraging. The combination of paint and nanofluid particle materials has boosted the accessibility to sun-based cooling processes and their capability to make ice of absorption. In addition, 0.6 was found to be a pretty good COP for the ammonia/calcium chloride solar system of absorption.

Energy, Economic and Environmental Effects of the Marine Diesel Engine Trigeneration Energy Systems

The paper discusses the possibility of applying the trigeneration energy concept (cogeneration + absorption cooling) on diesel-powered refrigerated ships, based on systematic analyses of variable energy loads during the estimated life of the ship on a predefined navigation route. From a methodological point of view, mathematical modeling of predictable energy interactions of a ship with a realistic environment yields corresponding models of simultaneously occurring energy loads (propulsion, electrical and thermal), as well as the preferred trigenerational thermal effect (cooling and heating). Special emphasis is placed on the assessment of the upcoming total heat loads (refrigeration and heating) in live cargo air conditioning systems (unfrozen fruits and vegetables) as in ship accommodations. The obtained results indicate beneficiary energy, economic and environmental effects of the application of diesel engine trigeneration systems on ships intended for cargo transport whose storage temperatures range from −25 to 15 °C. Further analysis of trigeneration system application to the passenger ship air conditioning system indicates even greater achievable savings.
