Effect of Waste Heat Utilization on the Performance of Low Temperature Rankine Cycle
Low temperature Rankine cycle is a prominent solution for power generation in Waste Heat Recovery (WHR) application. The performance of this cycle is affected by various parameters including characteristics of the heat source, working fluid and constraints in the system. In cases where the heat...
Solar heat recovery system using CO2 as working fluid
This article proposes a solar water heater system induced by natural convective flow using supercritical CO2 as a working fluid. The proposed solar water heater can produce thermal energy as hot water from solar thermal energy without any electric power consumption. In order to investigate the...
Thermal Characteristics in Supercritical CO2 Along Heating Tube
The system using CO2 as a refrigerant such as heat pump or Rankine cycle, depends greatly on the phase state and physical properties of CO2. In the present study, as a basic research on CO2 in the supercritical state, an experiment using a plane heating tube has been conducted, where two peaks of...
