Performance Investigation of Joule–Thomson Refrigeration System with Environment Friendly Refrigerant Mixtures

Performance and Leakage Investigations of Refrigeration and Airconditioning Systems Using Refrigerant Mixtures as Working Fluids

In spite of the advantages of zeotropic refrigerant mixtur~" [1], the industrial >tpplications of mixtures have been very limited up to now. The major problem is seen iu the leakages occuring in refrigeration plants and so a possible change in composition. Another disadvantage is that no simple methods for determination of the concentratiou insick the t:ydc i\rc available. This paper pre$ents t...

Refrigerant Choices for Commercial Refrigeration

Optimal Synthesis of a Cascade Refrigeration System of LNG Through MINLP Model for Pure Refrigerant Cycles

 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...

Impact of Refrigerant Charge over the Performance Characteristics of a Simple Vapour Compression Refrigeration System

Experimental investigation was done to find the role of capillary tube length and amount of refrigerant charge on the overall heat transfer coefficient in condenser and evaporator and actual COP of a simple vapour compression refrigeration system. It was concluded that increasing of the refrigerant charge in the system largely enhances the overall heat transfer coefficient in the evaporator by ...

Testing of Environment Friendly Refrigerant R290 for Water Cooler Application (RESEARCH NOTE)

This paper presents environment friendly refrigerant R290 as a solution to the environmental concerns like depletion of ozone layer and rise in global warming because of wide use of synthetic refrigerants R22 and R134a. The water cooler is the widely used refrigeration application in warm climatic countries. Refrigerant R22 and R134a are predominantly used refrigerants in water cooler refrigera...
