Abstract
The utility model provides a low temperature Bretton dual-cycle power generating device which is provided with two sealed cycle power generating systems. After heat absorption by a heat absorber, a working medium sequentially flows through a compressor, a condenser, a working medium pump, an evaporator and an expanded power generating unit to form the first sealed cycle power generating system; then, the other working medium sequentially flows through the condenser, the compressor and the expanded power generating unit to form the second sealed cycle power generating system; the heat absorber and the evaporator can absorb low temperature heat energy in air and water; and heat exchange between the high temperature and high pressure working medium of the first sealed cycle power generating system and the low temperature and low pressure working medium of the second sealed cycle power generating system is realized in the condenser. The low temperature Bretton dual-cycle power generating device does not need cold source outside the system, is high in heat efficiency and low in investment and cost, and successfully breaks through the technical difficulty that a low temperature thermal power generating system is low in heat efficiency.
