Problems solved by technology

In addition, the main difficulty to be solved by the new heat-driven combined cooling, heating and power system provided by the present invention is that under the structure of the engine and the refrigerator directly connected in series, the high temperature of the heating heat source (the temperature is higher than 300°C) will cause the refrigerator to be ineffective. The problem that the sound power input by the engine is greatly consumed, so that the system efficiency is low

Abstract

The invention discloses a heat driven combined cooling, heating and power system utilizing a high-temperature heat source. The system comprises a dual-efficiency free piston type Stirling refrigeratorloop, a reciprocating harmonic oscillator (1) and a linear power generator (10). The dual-efficiency free piston type Stirling refrigerator loop comprises an engine medium-temperature radiator (2), an engine heat regenerator (3), an engine heater (4), an engine heat buffer pipe (5), a regenerator medium-temperature radiator (6), a regenerator heat regenerator (7), a regenerator cold-end heat exchanger (8) and a regenerator exhaust unit (9) which are sequentially connected in an end-to-end mode. The reciprocating harmonic oscillator (1) communicates with the engine medium-temperature radiator(2) and the regenerator exhaust unit (9). The linear power generator (10) is connected with the reciprocating harmonic oscillator (1). The system is effectively driven by the high-temperature heat source, can reach a higher working pressure ratio, and achieves the high power density, compact structure and low machining and manufacturing cost.

Description

technical field [0001] The invention relates to the field of refrigerators / heat pumps, in particular to a heat-driven combined cooling, heating and power supply system utilizing a high-temperature heat source. Background technique [0002] Energy is an important material basis for human survival, economic development and social progress. Nowadays, global energy consumption continues to grow, and traditional non-renewable energy and traditional low-level energy consumption methods can no longer meet the growing material and cultural needs of human civilization. Therefore, energy saving and emission reduction is a key measure for our country to carry out modernization construction and economic development better. In view of this, at this stage, some thermally driven devices that can use high-temperature heat sources to achieve high-efficiency operation are developing rapidly. [0003] In 1816, the Scotsman O.R. Stirling proposed a patent for a thermodynamic cycle consisting ...
