Heat Pumping

Numerical simulation of heat and fluid flow in a basic and an orifice pulse tube refrigerator have been performed to visualize heat pumping generated in the regenerator and the pulse tube, and to clarify the difference in heat pumping caused by the phase difference between pressure and displacement of gas. Common components of the regenerator and the pulse tube are used in the basic and the orifice pulse tube refrigerator. The flow in the tube is assumed to be one-dimensional and compressible. As governing equations, the continuity, momentum and energy equations are used in this study. From the temperature and velocity field obtained as a result of the simulation, the relation between the displacement and the temperature change of gas elements is visually clarified, and consequently it is found that the characteristic that the temperatures of gas elements are nearly higher than those of the regenerator material or the pulse-tube wall during compression and lower during expansion is very important for the heat pumping in basic and orifice pulse tube refrigerators. Furthermore, the behavior of heat pumping in the basic and the orifice pulse tube refrigerator is illustrated by analyzing the relation between the displacement of gas elements and heat quantity transferred to the wall from the gas elements, and the difference in heat pumping between the basic and the orifice pulse tube refrigerator is made clear.

The Thermoacoustic Stirling Heat Engine(TASHE) designed by Backhaus, a device without moving parts which operates at a frequency of 85 Hz with an average pressure of 3 MPa that is capable of using sustainable energies, is applied to run an Inertance Pulse Tube Refrigerator(IPTR) with 1 W cooling power at 90 K. The coupling of these devices caused to eliminate all moving parts as well as miniaturizing the refrigerator to use for cooling superconducting magnets for MRI systems. A new method for the design of the IPTR performed by using numerical simulation of REGEN3.3. Moreover, to have a better vision of the overall configuration of IPTR and verify the Results of REGEN3.3, DeltaEC is used as an auxiliary software. Fortunately, both software results matched perfectly, and the performance of the IPTR was acoustically and thermodynamically ideal.
