Heat pump system for producing steam by using recuperator

A heat pump system for producing steam by using a recuperator, the heat pump system comprising:

• a refrigerant cycle, which comprises a compressor compressing a refrigerant, a heat exchanger heat-exchanging the refrigerant generated in the compressor with first circulation water, a condenser condensing the refrigerant by heat-exchanging the refrigerant generated in the heat exchanger with second circulation water, an expansion device expanding the refrigerant generated in the condenser and an evaporator evaporating the refrigerant generated in the expansion device and in which the refrigerant circulates;
• a first steam producing cycle, which comprises a first flash tank generating first steam by decompressing the first circulation water heated while passing through the heat exchanger and a first pump pumping the first circulation water generated in the first flash tank so as to circulate the first circulation water into the heat exchanger and in which the first circulation water is circulated so that the first steam is capable of being produced;
• a second steam producing cycle, which comprises a second flash tank generating second steam by decompressing the second circulation water heated while passing through the condenser and a second pump pumping the second circulation water generated in the second flash tank so as to circulate the second circulation water into the condenser and in which the second circulation water is circulated so that the second steam is capable of being produced;
• and
• a recuperator, which is provided within the refrigerant cycle, heat-exchanges the refrigerant generated in the condenser with the refrigerant introduced into the compressor so as to supercool the refrigerant generated in the condenser and elevates temperatures at an inlet and an outlet of the compressor so as to increase condensed heat of the condenser.
