Heat pump and refrigeration systems consume a large amount of energy annually around
the world. Heat exchanger is an important component of heat pump and refrigeration …

Abstracts Vapor compression refrigeration and heat pump (VCRHP) systems consume large
amounts of energy annually. Therefore, improving the VCRHP system efficiency holds …

This paper presents an evaluation of the performance of a refrigerant distributor with
visualization of the two-phase flow. The distributor is a typical conical design w/o the orifice …

This paper introduces the concept of separation of two-phase flow in condensers and
discusses its possible application of enhancing the heat transfer performance by capitalizing …

This paper presents the identification of slug/stratified-wavy, stratified-wavy and annular
regimes for horizontal flow (in the range of mass fluxes 40–150 kg m− 2 s− 1), and slug …

Flow regimes and void fraction in horizontal and vertical round smooth tubes ID 7 mm with
R134a in the adiabatic conditions (saturation temperature at 33° C) and low mass flux (40 …

Implementation of vapor-liquid separation during condensation enhances heat transfer and
reduces pressure drop. Multi-pass-orifice header as a liquid-separation unit has been widely …

Heat transfer and flow regime of two-phase R134a pulsating flow in an evaporator have
been studied experimentally in this work. Heat transfer coefficient was measured and liquid …

The novel alternatively-laminated-microchannel-tube (ALMT) heat exchanger contains two
pairs of vertical headers and alternatively laminated microchannel flat tubes, which realizes …

This paper presents an experimental study of two-phase R134a flow in the inlet header of
brazed plate heat exchangers and its effect on flow distribution among the channels …
