Energy Aspects in the Design of Air Coolers for Indirect Refrigeration Systems
نویسندگان
چکیده
In this paper a model for the performance prediction and optimization of air coolers for indirect refrigeration systems is presented. The model applies for finned rube air coolers operating under frosting conditions and considers the transient heat and mass transfer between humid air and air cooler surfaces. The model is extended with an energy consumption analysis for the compression refrigeration system. Further, the properties of several indirect coolan!-5 are added to the model so that a comparison of the performance of different coolants is possible. A parameter analysis including both price/performance and energy cost considerations is presented.

Saving energy is one of the most important challenges of todaychr('39')s world. Reducing electrical energy consumption in compressed air systems is one of the essential requirements for designing these systems. When using domestic air conditioners (dual air conditioners) in very hot areas (Khuzestan) their performance decreases and electric current consumption increases. Therefore, the use of n...

Using absorption refrigeration cycles instead of vapor compression refrigeration cycles can drastically decrease energy consumption. In these systems, high level of energy consumption is reduced due to the partially elimination of vapor compression refrigeration systems. On the other hand, utilization of waste heat of the plant, which is a very good opportunity for energy saving, is possible. ...

The exhaust gases of gas turbine power plant carry a significant amount of thermal energy that is usually expelled to the atmosphere this causes a reduction in net work and efficiency of gas turbine. On the other hand, the generated power and efficiency of gas turbine plants depend largely on the temperature of the inlet air, So that they both increase as the inlet air temperature decreases. Th...
