SOLAR THERMAL POWER GENERATION AND WATER HEATER DEVICE

摘要

PROBLEM TO BE SOLVED: To provide means for further promoting utilization of natural energy.SOLUTION: A carnot cycle binary power generation device, a solar heat collection device and a water heater are combined to each other to perform an efficient power generation and hot water supply. In the case where only the binary power generation through solar heat, at first, the refrigerant whose temperature is increased by a solar heat collection device 2 is flowed into an evaporator 3 of the binary power generation device, a temperature of the refrigerant of the binary power generation device is increased through heat exchanging operation to perform the power generation by the driving force of an expander 1. The refrigerant of low pressure and low temperature is heat exchanged with cooling water from a hot water storage tank 26 at a condenser and condensed, pressure thereof is increased by a refrigerant pump and the refrigerant returns to the evaporator. In the case where the binary power generation is carried out by solar heat and hot water storage is also carried out by the solar heat, refrigerant flowed out of the evaporator of the binary power generation device and still keeping high temperature from the solar heat collection device is utilized in addition to the solar heat power generation and a temperature thereof is increased through heat exchanging of cold water got from the hot water storage tank and utilized.SELECTED DRAWING: Figure 1
