<p>The present invention relates to an electricity-generating device employing a heat pump, comprising: an expansion turbine (170) in which an expansion valve is used to operate a heat pump used to cool and warm the inside of a room by means of a heat cycle in which an electrical energy supply is used to compress a coolant in a compressor (110) and the coolant passes through a condenser (120), the expansion valve (170) and an evaporator (160) before being sucked back in to the compressor (110); a four-way valve (240) which has a single intake port for taking in high-temperature and high-pressure coolant from the compressor (110), and a plurality of connecting ports for connecting with a plurality of connecting pipes, and of which the intake port is connected to the high-pressure output end of the compressor (110) and which only receives power when cooling is in operation; and a coupling (340) which uses magnetic force to transmit the rotational force of the expansion turbine (170) to a generator (330). A portion of the electrical energy (I1) input to the compressor (110) and the energy (I2) absorbed into the air via the evaporator, is converted to electrical energy (O1) via the generator (330), while another portion is converted to energy (O2) for either cooling or warming as required, and the remainder is converted to lost energy (O3), such that a relationship is established whereby I1 1 + O2.</p> |
