The aim of this work is to bring forward a new style heat exchanger about hollow fiber membrane module, and to analyze the performance which can expectantly be applied in the lithium bromide absorption refrigeration system. Polyvinylidene fluoride hollow fiber membrane module was adopted as the new style solution heat exchanger, hot feed solution from the generator flowed into the lumen side of...

The objective of this paper is to develop a mathematical model for thermodynamic analysis of an absorption refrigeration system equipped with an adiabatic absorber using a lithium-bromide/water (LiBr/water) pair as the working fluid. The working temperature of the generator, adiabatic absorber, condenser, evaporator, the cooling capacity of the system, and the ratio of the solution mass flow ra...

This study aims to investigate the applicability of vacuum membrane distillation for concentrating aqueous lithium bromide solution, and to analyze the feasibility of applying vacuum membrane distillation process to the absorption refrigeration system. Hydrophobic polyvinylidene fluoride (PVDF) was adopted as the membrane material, and was made into hollow fiber membrane module. Commercial aque...

We study the phenomenon of absorption refrigeration, where refrigeration is achieved by heating instead work, in two different setups: a minimal set up based on coupled qubits, and non-linearly resonators. Considering ZZ interaction between we outline basic ingredients required to achieve cooling. Using local as well global master equations, observe that inclusion XX type term qubit-qubit coupl...

In this study, the problem of a parallel connected power and absorption cooling cogeneration system was analyzed and then an improved configuration based on this system was proposed. This system can make cascade utilization of the turbine exhaust heat. By varying turbine outlet pressure, different turbine exhaust vapor temperatures can be obtained, resulting in different amounts of heat that ca...
