Problems solved by technology

However, due to the too many access points of the refrigerator on the engine loop, the distribution of sound power in the system is extremely complicated, and it is difficult to design and manufacture
In a word, the existing inventions still can not provide a simple, effective and high-efficiency technical way of combined cooling, heating and power supply.

Abstract

The invention relates to a travelling wave thermo-acoustic combined cooling heating and power system which is composed of at least three travelling wave thermo-acoustic engines, at least one travelling wave thermo-acoustic refrigerating machine, a linear generator and resonance units. The travelling wave thermo-acoustic engines are connected in an end-to-end mode through the resonance units to form a loop. One end of the travelling wave thermo-acoustic refrigerating machine is laterally connected to the resonance units, and the other end of the travelling wave thermo-acoustic refrigerating machine is connected with the linear generator. The travelling wave thermo-acoustic combined cooling heating and power system converts heat energy into acoustic power through the travelling wave thermo-acoustic engines, the travelling wave thermo-acoustic refrigerating machine achieves refrigeration through a part of acoustic power, the linear generator converts the acoustic power at an outlet of the travelling wave thermo-acoustic refrigerating machine into electric energy and provides a suitable phase position for the travelling wave thermo-acoustic refrigerating machine, and the performance of the travelling wave thermo-acoustic refrigerating machine is improved. The temperature of cooling water of each cooling machine is increased to be used for life heat supply. Compared with the prior art, the travelling wave thermo-acoustic combined cooling heating and power system can achieve output of cold energy and electric energy at the same time in one device, the systematic complexity is reduced, the reliability is improved, and the travelling wave thermo-acoustic combined cooling heating and power system has the advantages of being high in efficiency, flexible in power and the like, and can be applied to the field of utilization of energy such as solar energy, industrial waste heat and biomass energy.

Description

technical field [0001] The invention relates to a combined cooling, heating and power system, in particular to a traveling wave thermoacoustic combined cooling, heating and power system. Background technique [0002] In many occasions in industrial production and residential life, cooling, heating, and electricity resources are required at the same time. In the field of energy, a distributed combined cooling, heating and power supply scheme was proposed many years ago, which can simultaneously provide electricity, cold energy and heat energy for domestic use. The existing combined cooling, heating and power systems mostly use natural gas or liquid fuel as primary energy, use gas turbines, internal combustion engines or steam turbines to generate electric energy, and then use absorption or adsorption refrigeration to convert the high-temperature waste heat of the above systems into cold energy. The waste heat which is slightly higher than the ambient temperature is used for ...
