Power production from low grade heat and waste heat does not only mitigate environmental
impact but also improve energy efficiency and reduce energy cost. The type and design of …

In the field of low-grade heat energy utilization, organic Rankine cycle (ORC) has gained
enough worldwide attention in recent years. Scroll expander has become a good candidate …

Scroll expanders are currently attracting interest for integration in small scale organic
Rankine cycle (ORC) waste heat recovery applications and have been subject to significant …

Adding liquid to the working fluid in scroll compressors can allow for a working process that
approaches isothermal compression. When liquid flooding and regeneration is applied to …

R32 has been considered as an important alternative in the phase-out of
hydrochlorofluorocarbons (HCFCs) due to its advantages such as relatively low global …

The scroll compressor is an essential component in air conditioning and heat pump systems.
This study examined an electric scroll compressor using R22 refrigerant, focusing on how …

This paper deals with the scroll compressor, which is a machine used for compressing air or
refrigerant. By using a novel reference frame, it proposes an original way of describing the …

A scroll air motor, also known as a scroll expander, is a relatively new concept to pneumatic
actuators. Its unique structure leads to its feature of high ability in energy conversion. In …

The built-in volume ratio of variable wall thickness scroll expanders can be increased
without increasing the number of scroll turns and the expander size in contrast to constant …

The back-pressure mechanism plays an important role in the performance and efficiency of
the scroll compressor. In this work, the level of back pressure of an asymmetrical algebraic …
