Generating device based on absolute temperature difference of evaporator and condenser in air conditioner and refrigerator

Abstract

The invention discloses a generating device which can improve temperature-electricity conversion efficiency of a temperature difference generating module and utilize absolute temperature difference of an evaporator and a condenser in an air conditioner and a refrigerator to obtain regeneration energy. The structure thereof includes a temperature difference generating module, a pair of temperature collecting faces of the temperature difference generating module are respectively jointed with an evaporator temperature collector arranged in an evaporator loop in series and a condenser temperature collector arranged in the condenser loop in series. The invention adopts the structure that a pair of temperature collecting faces are respectively jointed with the evaporator temperature collector arranged in the evaporator loop in series and the condenser temperature collector arranged in the condenser loop in series, so as to obtain large and invariable absolute temperature difference, thus improving the temperature-electricity conversion efficiency of the temperature difference generating module and improving the practical value.

Description

Technical field [0001] The present invention relates to a power generation device based on temperature difference, in particular to a power generation device based on the absolute temperature difference between an evaporator and a condenser in an air conditioner and a refrigerator. Background technique [0002] As we all know, there is a relative temperature difference between the evaporator and condenser in air conditioners and refrigerators and the external environment, while there is an absolute temperature difference between the evaporator and the condenser. In today's increasingly scarce energy, with the maturity of thermoelectric power generation technology, thermoelectric power generation technology has become a new force in waste heat utilization and renewable energy, and has made a greater contribution to energy conservation. The invention patent with application number 200710007161.3 filed by others to the National Bureau on February 5, 2007 and published by the Nationa...

AI Technical Summary

Problems solved by technology

However, because the temperature difference between the evaporator and the external environment is small, and the thermoelectric conversion efficiency is low and unstable due to changes in the air environment, only about 50% of the existing temperature difference energy is collected and utilized.
