Design and Manufacturing of Organic Rankine Cycle (ORC) System Using R-134a as Working Fluid with Solar Collector as Source Energy

Abstract

Renewable energy sources such as solar heat, wind energy, geothermal, biomass and exhaust heat is one way to overcome the crisis of energy and environment in the world. Organic Rankine Cycle (ORC) is a power generation system modified from Rankine Cycle by using organic liquid with low boiling point as working fluids such as R-134a, therefore various types of heat sources can be use. This research was design and manufacture organic Rankine cycle by using R-134a as working fluid with solar collector as the source of energy. The design of this research resulted in the length of the evaporator tube is 14.5 m, length of condenser is 13.9 m and the length of solar collector tube is 9.4 m. The helical Diameter of evaporator and condenser are 250 mm, and the high of helical evaporator 290 mm and condenser 280 mm. Organic Rankine cycle system is designed to produced 534.4 Watt, but when the experiment is carried out the system generates energy of 305 Watt with the efficiency of 4.30%

Geothermal Power Generation: Harnessing Electrical Energy Through The Organic Rankine Cycle (ORC) System

“…The R-134a, as a standard refrigerant in refrigeration systems, is attracting attention as a potential option at low temperatures such as 95ºC [10] [11]. However, the high-pressure aspect of R-134a indicates that system design must consider this aspect carefully [12]. R-11, with its low boiling point at atmospheric pressure, shows promising thermodynamic properties at low temperatures.…”

Solar Thermal Collector System with Parabolic Collector for Applications in Organic Rankine Cycle: Design, Manufacturing and Testing

“…Naibaho et al, [26] designed a helical type evaporator and condenser and a flat plate collector as a solar heat absorber, and found that the ORC system produced 0.305 kW of electrical energy and 4.3% thermal efficiency.…”
