일반적으로, 히트펌프 시스템은, 기본적으로 냉방 사이클과 난방 사이클을 동일한 유닛 안에 내장하여 냉각, 가열이 겸용으로 이루어지며, 한 대의 유닛으로 하절기에는 냉방 사이클에 의해 냉방을 수행하고, 동절기에는 역사이클로 전환시켜 난방 및 급탕을 수행하는 시스템이다.In general, the heat pump system is basically a cooling cycle and a heating cycle in the same unit, the cooling and heating are combined, one unit performs the cooling by the cooling cycle in the summer, the reverse cycle in the winter System to perform heating and hot water supply.

상기와 같이 구성된 본 발명인 급탕기능을 갖는 하이브리드 히트펌프 시스템은, 실내기에 구비된 마이컴 콘트롤러(미도시)에 의해 제어되며 사용자가 냉방과 급탕모드를 선택하여 구동시키면 냉방모드와 급탕모드가 동시에 가동되는 것으로, 실내온도가 설정된 희망온도에 도달하면 급탕단독모드로 절환되고 급탕열교환기(100)의 관수온도가 설정된 희망온도에 도달하면 냉방 단독모드로 자동 절환되며 양 모드가 각각 설정된 희망온도에 도달하면 양 모드는 운전대기상태로 전환된다.The hybrid heat pump system having a hot water supply function of the present invention configured as described above is controlled by a microcomputer controller (not shown) provided in an indoor unit, and when the user selects and drives the cooling and hot water mode, the cooling mode and the hot water mode are operated simultaneously. When the indoor temperature reaches the set desired temperature, it is switched to the hot water supply alone mode, and when the watering temperature of the hot water heat exchanger 100 reaches the set desired temperature, it is automatically switched to the cooling single mode, and when both modes reach the set desired temperature, respectively. Both modes are switched to standby mode.

또한, 실내기에 구비된 마이컴 콘트롤러(미도시)에 의해 제어되며 사용자가 난방과 급탕모드를 선택하여 구동시키면 난방모드와 급탕모드가 동시에 가동되는 것으로, 실내온도가 설정된 희망온도에 도달하면 급탕단독모드로 절환되고 급탕열교환기(100)의 관수온도가 설정된 희망온도에 도달하면 난방 단독모드로 자동 절환되며 양 모드가 각각 설정된 희망온도에 도달하면 양 모드는 운전대기상태로 전환된다.In addition, it is controlled by a microcomputer controller (not shown) provided in the indoor unit, when the user selects and drives the heating and hot water mode, the heating mode and the hot water mode are operated simultaneously. When the indoor temperature reaches the set desired temperature, the hot water alone mode When switched to and the water temperature of the hot water supply heat exchanger 100 reaches the set desired temperature is automatically switched to the heating only mode, and when both modes reach the set desired temperature, both modes are switched to the operation standby state.

본 발명인 급탕기능을 갖는 하이브리드 히트펌프 시스템의 냉방은, 압축기(1)에서 토출된 냉매가스가 실외열교환기(3)에서 방열되어 응축액화한 후, 실내기(20)의 수액기 출구에서 실내측 팽창밸브(4)를 지나 저온저압액으로 단열팽창한 다음, 실내열교환기(5)로 유입되어 실내의 공기로부터 열을 흡입하여 저온저압가스로 상변화되어 급탕열교환기에서의 급탕수 온도의 하락을 방지하기 위해 상기 냉매제어밸브(50)에 의해 우회되어 4방변밸브(2)를 지나 다시 압축기(1)로 유입되는 사이클이 반복되어 이루어진다.In the cooling of the hybrid heat pump system having the hot water supply function of the present invention, the refrigerant gas discharged from the compressor (1) is radiated by the outdoor heat exchanger (3) to condense and liquefy, and then expands indoors at the outlet of the receiver of the indoor unit (20). After adiabatic expansion with low temperature and low pressure liquid through the valve (4), flows into the room heat exchanger (5), sucks heat from the air in the room, changes to low temperature low pressure gas, and reduces the temperature of the hot water supply in the hot water heat exchanger. In order to prevent the refrigerant control valve 50 is bypassed by passing through the four-way valve (2) to the compressor (1) is repeated repeatedly.

또한, 난방은, 압축기(1)에서 토출된 냉매가스가 실내기(20)에 설치된 급탕 열교환기(100)를 우회하여 실내열교환기(5)에서 방열하여 응축액화 하는 바, 이 때 응축열을 송풍팬으로 실내로 유입시켜 실내의 난방이 이루어진다. 또한, 응축액화된 냉매가스는 실내기의 수액기에 인입되어 실외측 팽창밸브(4)를 지나 저온저압액으로 단열팽창한 후, 실외열교환기(3)에서 외부의 열을 흡입하여 저온저압가스로 상변화한 후, 4방변 밸브(2)를 지나 다시 압축기(1)로 유입되는 사이클이 반복되어 이루어진다.In addition, the heating of the refrigerant gas discharged from the compressor (1) bypasses the hot water supply heat exchanger (100) installed in the indoor unit (20) to radiate heat in the indoor heat exchanger (5) to condensate the liquid, and at this time, the condensation heat is blown fan Inflowing into the room is achieved by heating the room. In addition, the condensed refrigerant gas is introduced into the receiver of the indoor unit, and adiabaticly expands with a low temperature low pressure liquid through the outdoor expansion valve (4), and then sucks external heat from the outdoor heat exchanger (3) to form a low temperature low pressure gas. After the change, the cycle flowing through the four-way valve (2) again into the compressor (1) is repeated.

이 때, 상기 실내기(20)의 실내열교환기(5) 일측에 구비된 난방보조히터(130)에 의해 실내의 공기온도가 상승되는 시간이 빠르게 이루어짐으로써, 난방효율성이 크게 향상된다.At this time, by the heating auxiliary heater 130 provided on one side of the indoor heat exchanger 5 of the indoor unit 20 to increase the temperature of the indoor air is made faster, the heating efficiency is greatly improved.

본 발명인 급탕기능을 갖는 하이브리드 히트펌프 시스템에 의한 급탕은, 상 기 급탕열교환기(100)의, 토출부(111)로부터 토출된 급탕수를 공급받아 사용하는 것으로, 직수가 유입되는 유입부(112)로부터 유입된 직수는 상기 급탕열교환기(100)의 내부측에 구비되는 순환관(110)의 응축열량에 의해 열교환이 이루어짐에 따라 수온이 상승되게 됨으로써 사용자는 급탕을 공급받아 사용할 수 있다.The hot water supply using the hybrid heat pump system having the hot water supply function of the present invention is used by receiving the hot water discharged from the discharge portion 111 of the hot water heat exchanger 100, and the inflow portion 112 into which direct water flows. The direct water flowing from the user is supplied with the hot water supply as the water temperature is increased by heat exchange by the heat of condensation of the circulation pipe 110 provided inside the hot water heat exchanger 100.

또한, 급탕이 공급되는 동안에 냉방을 가동할 경우, 상기 냉매제어밸브(50)에 의해 순환되는 냉매가스가 급탕열교환기(100)측으로 흐르지 않도록 하여, 냉매가스가 급탕열교환기(100)의 축열수와 열교환하지 않도록 하고, 그에 따라 급탕열교환기(100)의 열교환효율이 상승되어 냉방과 상관없이 사용자는 필요한 온도의 온수를 공급받아 사용할 수 있도록 한다.In addition, when cooling is operated while the hot water supply is supplied, the refrigerant gas circulated by the refrigerant control valve 50 does not flow to the hot water supply heat exchanger 100 side, and the refrigerant gas flows into the heat storage water of the hot water supply heat exchanger 100. The heat exchange efficiency of the hot water supply heat exchanger 100 is increased so that the user can receive and use hot water at a required temperature regardless of cooling.

이와 같이 냉매제어밸브(50)에 의해 순환되는 냉매가 급탕열교환기(100)에 간섭되는 것이 방지됨으로써 냉매사이클의 냉매효율이 저하되는 것이 차단될 수 있어 실내 냉방효과 역시 저하되지 않는다.As such, the refrigerant circulated by the refrigerant control valve 50 may be prevented from interfering with the hot water supply heat exchanger 100, and thus, the refrigerant efficiency of the refrigerant cycle may be prevented from being lowered.

또한, 실외 열교환기(3) 제상시의 제상흡열량 보완을 위해, 압축기(1) 흡입 저압관 측에 설치된 온도감지센서(40)의 감지신호에 따라, 냉매가스가 냉매제어밸브(50)를 경유하지 아니하고, 순환관(110)을 경유할 수 있도록 하는 흡열제어밸브(150)를 더 구비한다.
따라서, 제상시 상기 온도감지센서(40)가 동작하면, 급탕열교환기(100)의 내부를 통과하도록 설치된 순환관(110)을 통해 냉매가스가 순환됨으로써, 상기 냉매가 급탕열교환기(100)의 축열수로부터 열을 흡열 하도록 자동으로 냉매제어밸브(50)가 제어되고, 그에 따라 제상 구동시에 제상작업이 더욱 수월하게 이루어짐은 물론, 제상을 자동적으로 보완할 수 있도록 한다.
In addition, in order to compensate for the defrost heat absorption at the time of defrosting the outdoor heat exchanger (3), the refrigerant gas is supplied to the refrigerant control valve (50) according to the detection signal of the temperature sensor (40) installed on the suction low pressure pipe side of the compressor (1). It is further provided with an endothermic control valve 150 to pass through the circulation pipe 110, not via.
Therefore, when the temperature detection sensor 40 operates during defrosting, the refrigerant gas is circulated through the circulation pipe 110 installed to pass through the inside of the hot water supply heat exchanger 100, thereby allowing the refrigerant to flow out of the hot water supply heat exchanger 100. The refrigerant control valve 50 is automatically controlled to absorb heat from the heat storage water, thereby making defrosting work easier during defrost driving and automatically supplementing the defrost.
