Thermoacoustic Refrigerator

open access: yes, 2003
Thermoacoustic refrigerators have typically been designed to cool an isolated working fluid, necessitating a heat exchanging device to draw heat from the outside target fluid into the cooled working fluid. For example, a thermoacoustic refrigerator designed to chill air might utilize argon as an isolated working fluid, necessitating a heat exchanger to

Study on Coupling in a Thermoacoustic Driven Pulse Tube Refrigerator

open access: yesZhileng xuebao, 2018
Thermoacoustic-driven pulse tube refrigerators are usually coupled directly or by long tubes called acoustic amplifiers. With these coupling methods, the efficiency of the whole system is quite low because of the nonideal acoustic field and flow losses ...

Effects of cold‐end temperature and heat load on the cooling characteristics of a pulse tube refrigerator

open access: yesEnergy Science &Engineering, Volume 8, Issue 3, Page 731-739, March 2020., 2020
A coupling model of the PTR by using REGEN and DeltaEC is built for investigating the effects of the cold‐end temperature and cold load on the cooling efficiency. Some experiments are performed on a PTR working at different cold‐end temperature and cold load which are in good agreement with the simulation results.
