Title:
SYSTEM USING THERMOACOUSTIC ENGINE TO DRIVE THERMOACOUSTIC HEAT PUMP
Document Type and Number:
WIPO Patent Application WO/2018/107827
Kind Code:
A1
Abstract:
A system using a thermoacoustic engine to drive a thermoacoustic heat pump. The system comprises, connected between a compressor (18) and an electric generator (19) in sequence, a thermoacoustic engine and a thermoacoustic heat pump; the thermoacoustic engine is coupled to the thermoacoustic heat pump by means of a harmonic oscillator; the thermoacoustic engine is used for gradually amplifying acoustic energy from the compressor by means of heating; the thermoacoustic heat pump is used for gradually reducing the amplified acoustic energy so as to convert the acoustic energy into heat energy and electrical energy respectively; and the harmonic oscillator is used for forming a traveling-wave sound field. The thermoacoustic engine and the thermoacoustic heat pump are in coupling connection by means of the harmonic oscillator in the system, so that the system not only can effectively utilize low grade heat to achieve a high-efficiency refrigeration or heat supply function but also can utilize the cooperative work between the electric generator and the harmonic oscillator to supplement the converted electrical energy to the compressor by means of the electric generator, thereby effectively improving the operating efficiency of the system and reducing the energy loss of the system.
