There is an advantage that can be used by continuously circulating water without the need for supplemental water used in.

이하, 본 발명의 최선의 실시예를 첨부한 도면을 의거하여 상세히 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings, the best embodiment of the present invention will be described in detail.

도 1은 본 발명의 실시예에 따른 다단 응축 난방시스템의 구성도이다.1 is a block diagram of a multi-stage condensation heating system according to an embodiment of the present invention.

도시된 바와 같이, 다단 응축 난방시스템은 온수탱크(20), 저수조(30), 압축기(10), 온수용응축기(12), 냉매용응축기(13), 증발기(14), 바이패스라인(19)을 구비한다.As shown, the multi-stage condensation heating system includes a hot water tank 20, a water reservoir 30, a compressor 10, a hot water condenser 12, a refrigerant condenser 13, an evaporator 14, and a bypass line 19. ).

더욱 자세히 살펴보면, 온수탱크(20)는 난방 및 온수로 사용하기 위한 온수 가 저장되고, 저수조(30)는 압축기(10)로 공급되는 냉매의 온도를 냉각시키기 위한 순환수가 저장된다.Looking in more detail, the hot water tank 20 is stored hot water for use as heating and hot water, the reservoir 30 is stored in the circulation water for cooling the temperature of the refrigerant supplied to the compressor (10).

온수용응축기(12)는 온수탱크(20)에서 공급된 온수와 압축기(10)에서 공급되는 고온 고압의 냉매를 제공받아 온수의 온도를 증가시켜 난방 및 온수로 사용된다. The hot water condenser 12 receives hot water supplied from the hot water tank 20 and a high temperature and high pressure refrigerant supplied from the compressor 10 to increase the temperature of the hot water and is used as heating and hot water.

냉매용응축기(13)는 온수용응축기(12)에서 배출된 냉매와 저수조에서 배출된 순환수와 열교환시켜 냉매의 온도가 일정하게 배출되도록 열교환시킨다. 이때, 최종적으로 배출되는 냉매의 온도는 54.5~55℃이 바람직하며, 이러한 냉매의 온도를 유지하기 위하여 1개 이상의 냉매용응축기가 사용될 수 있다.The refrigerant condenser 13 exchanges heat with the refrigerant discharged from the hot water condenser 12 and the circulating water discharged from the storage tank so that the temperature of the refrigerant is constantly discharged. At this time, the temperature of the finally discharged refrigerant is preferably 54.5 ~ 55 ℃, one or more refrigerant condenser may be used to maintain the temperature of the refrigerant.

증발기(14)는 냉매용응축기(13)에서 배출된 냉매와 상기 저수조에서 배출된 순환수를 열교환시켜 냉매의 온도를 하강킨다. The evaporator 14 heats the refrigerant discharged from the refrigerant condenser 13 and the circulating water discharged from the reservoir to lower the temperature of the refrigerant.

이때, 저수조(30)와 냉매용응축기(13) 사이에는 순환수가 공급되는 제1순환수공급라인(16)이 형성되고, 냉매용응축기(13)와 증발기(14) 사이에는 순환수가 제2순환수공급라인(17)이 형성된다. 또한, 제1순환수공급라인(16)의 일측에는 냉매용응축기를 거치지 않고 제2순환수공급라인(17)으로 순환수를 제공하는 바이패스라인(19)과 바이스패스라인으로 제공되는 순환수의 량을 조절하는 조절밸브(18)가 형성된다. 이때, 조절밸브(18)는 압축기로 공급되는 냉매의 온도를 체크하는 온도센서(40)에 의해 제어된다.At this time, a first circulating water supply line 16 is formed between the reservoir 30 and the refrigerant condenser 13 to supply circulating water, and a second circulation of the circulating water is between the refrigerant condenser 13 and the evaporator 14.

이하, 본 발명의 다단 응축 난방시스템의 동작에 대하여 구체적으로 설명한다.Hereinafter, the operation of the multi-stage condensation heating system of the present invention will be described in detail.

압축기(10)에서 고온 고압으로 압축된 냉매는 온수용응축기(12)로 공급되어 온수탱크(20)로부터 유입된 온수와 열교환하여 온수의 온도는 증가시키고, 냉매의 온도는 낮아진다. 온도가 증가된 온수는 난방 및 온수용으로 공급된다. 이때, 온수용응축기(12)에서 열교환되어 냉매는 약 90~120℃에서 55~70℃로 응축, 냉각된다.The refrigerant compressed by the high temperature and high pressure in the compressor 10 is supplied to the hot water condenser 12 to exchange heat with hot water introduced from the hot water tank 20 to increase the temperature of the hot water, and lower the temperature of the refrigerant. Hot water with increased temperature is supplied for heating and hot water. At this time, the heat exchanger in the hot water condenser 12, the refrigerant is condensed and cooled from about 90 ~ 120 ℃ to 55 ~ 70 ℃.

온수용응축기(12)에서 배출된 냉매는 냉매용응축기(13)로 공급되며 제1순환수공급라인(16)을 따라 유입된 순환수와 온도로 배출되도록 열교환된 후에 다시 증발기(14)에서 제2순환수공급라인(17)으로 유입된 순환수와 열교환된다. 이때, 냉매용응축기(13)에서 배출되는 냉매의 온도는 54.5~55℃로 최종적으로 배출되어 팽창변(15)로 유입되는 것이 바람직하며, 이러한 냉매의 온도를 유지하기 위하여 1개 이상의 냉매용응축기가 사용될 수 있다.The refrigerant discharged from the hot water condenser 12 is supplied to the refrigerant condenser 13 and heat-exchanged so as to be discharged to the circulating water and the temperature introduced along the first circulating water supply line 16, and then the evaporator 14 Heat exchange with the circulating water introduced into the two-circulating water supply line (17). At this time, the temperature of the refrigerant discharged from the refrigerant condenser 13 is finally discharged to 54.5 ~ 55 ℃ to enter the expansion valve 15, in order to maintain the temperature of the refrigerant at least one refrigerant condenser Can be used.

한편, 압축기(10)로 공급되는 냉매의 온도를 체크·비교하는 온도센서(40)에서 체크된 냉매의 온도에 따라 저수조에서 배출되는 순환수를 바이패스라인(19)을 통해 제2순환수공급라인(17)에서 혼합하여 증발기(14)를 거쳐 저수조(30)로 공급되는 순환수의 온도를 일정하게 유지킨다. 예를 들면 온도센서에서 체크된 냉매의 온도가 10~15℃인 경우이면, 조절밸브에서 제1순환수공급라인으로 냉매용응축기로 80%의 순환수를 공급하고, 바이패스라으로 나머지 10%의 순환수를 공급하여 제2순 환수공급라인에서 혼합하여 증발기로 공급하면 증발기에서 배출되는 순환수의 온도를 약 13~15℃로 유지시킬 수 있다.Meanwhile, the second circulating water is supplied through the bypass line 19 to the circulating water discharged from the reservoir according to the temperature of the refrigerant checked by the temperature sensor 40 for checking and comparing the temperature of the refrigerant supplied to the compressor 10. Mixing in line 17 maintains a constant temperature of circulating water supplied to reservoir 30 via evaporator 14. For example, if the temperature of the refrigerant checked by the temperature sensor is 10 ~ 15 ℃, 80% of the circulating water is supplied from the control valve to the first circulating water supply line to the refrigerant condenser and the remaining 10% to the bypass. By supplying the circulating water of the second circulating water supply line is mixed with the supply to the evaporator can maintain the temperature of the circulating water discharged from the evaporator at about 13 ~ 15 ℃.
