Waste Heat Recovery System by Using Water Chamber in Between Compressor and Condenser

Ballast Water Analysis And Heat Treatment Using Waste Heat Recovery Systems On Board Ships

Ballast water contains a variety of organisms including bacteria, viruses and the adult and larval stages of the many marine and coastal plants and animals. As such, it poses serious ecological, economic and health problems and has serious negative effects on the global environment. This paper presents a new efficient ballast water analysis and heat treatment system using waste heat recovery sy...

Waste Heat Recovery of a PEMFC System by Using Organic Rankine Cycle

In this study, two systems are brought forward to recover the waste heat of a proton exchange membrane fuel cell (PEMFC), which are named the organic Rankine cycle (ORC), and heat pump (HP) combined organic Rankine cycle (HPORC). The performances of both systems are simulated on the platform of MATLAB with R123, R245fa, R134a, water, and ethanol being selected as the working fluid, respectively...

Measurement of water holding capacity using a condenser-chamber TEWL instrument

High Efficiency Compressor-Condenser in a Single Hermetic Component for Heat Pumps

A unit that encloses a motor-compressor and a condenser of refrigerant fluid in a single hermetic casing is presented. After a description of the general advantages of the component compared with the traditional solution, as far as weight, size, cost and very low noise emission are concerned, experimental test results are presented. COP values in different working conditions show that a good en...
