<p>PURPOSE: A hot water generating apparatus using a heat pump is provided to stably work and improve durability and to always supply hot water in a constant temperature. CONSTITUTION: A hot water generating apparatus using a heat pump comprises a heat exchanging cycle including a compressor(10), an expansion valve(30), first and second heat exchangers(20,40), a hot water tank(50) storing hot water generated by heat-exchanging cold water supplied to the first heat exchanger with working fluid, an auxiliary heat exchanger(25) installed between the compressor and the expansion valve and delivered with working fluid transmitted from the compressor, an outer water tank(60) supplying heat for evaporating working fluid in the second heat exchanger by receiving the heat of working fluid from the auxiliary heat exchanger, and pressure control valves(70,70'), which is installed to a conduit(80) connecting the compressor, the expansion valve, and the first and second heat exchangers, operating working fluid along the conduit when the pressure of working fluid reaches the set pressure.</p> |
