통상적으로 실내를 냉방하는 장치와 난방하는 장치가 각각 분리되어 구성되는 것이 일반적이기는 하지만, 최근에는 하나의 장치로 하절기에는 실내를 냉방시킬 수 있고 동절기에는 실내를 난방시킬 수 있는 장치가 개발되었는데, 이의 대표적인 것이 공기열을 열원으로 하는 공기열 히트펌프식 냉난방장치이다.In general, a device for cooling a room and a device for heating are generally configured separately, but recently, a device for cooling a room in summer and a room for heating in winter has been developed. A typical example is an air heat heat pump type air conditioner using air heat as a heat source.
공기열 히트펌프식 냉난방장치는 하절기에 실내측열교환기에서 열을 흡수하여 실외측열교환기를 이용하여 열을 방열시킴으로써 냉방을 하고, 동절기에는 반대로 실외측열교환기에서 열을 흡수하여 실내에 설치된 실내측열교환기를 이용하여 열을 방열시킴에 따라 난방을 하는 장치로서, 그 사이클의 구성은 냉방운전시는 증발열을 이용하는 냉동사이클과 동일하며, 난방운전시는 반대로 응축열을 이용하는 난방사이클로 구성된다.Air heat heat pump type air conditioning system absorbs heat from indoor side heat exchanger in summer and radiates heat by using outdoor side heat exchanger to cool.In winter, indoor side heat exchanger is installed indoors by absorbing heat from outdoor side heat exchanger. A device for heating by radiating heat by using a machine, the configuration of the cycle is the same as the refrigeration cycle using the evaporative heat during the cooling operation, it consists of a heating cycle using condensation heat in the heating operation.
공기열 히트펌프식 냉난방장치는 열을 흡수하고 방열하는 원리에 따라 압축식, 화학식, 흡수식, 흡착식 등으로 분류되는데, 그 중 가정용으로 많이 적용되는 형식은 압축식으로, 그 기본적인 구성요소는 저온부 열교환기인 증발기, 압축기, 고온부 열교환기인 응축기, 팽창밸브의 4개로 구분되며, 작동유체인 열매체는 증발, 압축, 응축, 팽창의 변화를 계속하면서 순환라인을 따라 순환된다.Air heat heat pump type air conditioner is classified into compression type, chemical formula, absorption type and adsorption type according to the principle of absorbing heat and radiating heat. Among them, the most commonly used type is compression type, and its basic component is low temperature heat exchanger. It is divided into four parts: an evaporator, a compressor, a condenser which is a high temperature heat exchanger, and an expansion valve. The heating medium, which is a working fluid, is circulated along a circulation line while changing evaporation, compression, condensation, and expansion.
그러나 종래의 공기열 히트펌프식 냉난방장치의 경우에는 동절기 대기온도가 영하로 떨어지는 관계로 실외측열교환기로부터 열이 제대로 흡수되지 않아 난방운전이 제대로 이루어지지 않는 문제점이 있으며, 이를 해소하기 위하여 부족분의 난방열량을 전기히터로 보충하여야 하는 문제점이 있었다.However, in the case of the conventional air heat heat pump type air-conditioning device, there is a problem that the heating operation is not properly performed because heat is not properly absorbed from the outdoor side heat exchanger because the winter air temperature drops to below zero. There was a problem that the amount of heat must be replenished with an electric heater.
또한 동절기에는 냉방부하를 실외측열교환기를 통해 버리기 때문에 실외측열교환기에 적상이 생길 수 밖에 없으며 이로 인해 효율이 저하됨은 물론 고장이 발생되는 문제가 있으며, 정상운전을 위해서는 적상을 주기적으로 제거해야 하는 바 전체 장치의 제어가 용이하지 않은 문제점이 있었다.In addition, in winter, the cooling load is discarded through the outdoor side heat exchanger, which inevitably leads to a drop in the outdoor side heat exchanger. As a result, there is a problem that the efficiency is lowered and a breakdown occurs. There was a problem that the control of the whole device is not easy.
최근 전술한 문제점을 개선하기 위해 많은 연구가 행해지고는 있으나, 동절기 외기온도의 저하로 인한 난방효율의 저하문제는 해소되고 있지 않고 있다.Recently, many studies have been conducted to improve the above-mentioned problems, but the problem of lowering the heating efficiency due to the decrease of the outside air temperature in winter has not been solved.
또한 종래의 공기열 히트펌프식 냉난방장치의 경우에는 냉난방운전의 전환이 냉매순환관로와 열매체순환관로로 제어되는 구조로 형성되는 관계로 전체적인 제어시스템이 복잡힐 뿐만 아니라 유로변경밸브가 완전 폐쇄되지 않을 경우 냉난방사이클이 정상적으로 운전되지 못하는 문제점이 있었다.In addition, in the case of a conventional air heat heat pump type air conditioner, the switching of the cooling and heating operation is formed in a structure controlled by the refrigerant circulation passage and the heat medium circulation passage, which not only complicates the overall control system but also does not completely close the flow change valve. There was a problem that the heating and cooling cycle does not operate normally.
뿐만 아니라 종래의 공기열 히트펌프식 냉난방장치의 경우에는 초기 정상운전을 위해 냉방부하를 소모시키기 위한 난방열량을 전기히터를 통해 제공하는 구조로 구성되었으나, 전기히터는 내구성에 문제가 있어 그 고장시 공기열 히트펌프식 냉난방장치 전체가 소손되는 문제점이 있다. In addition, in the case of the conventional air heat heat pump type air-conditioning unit, the heating heat is provided through the electric heater to consume the cooling load for the initial normal operation. There is a problem that the entire heat pump type air-conditioning device is burned out.
본 발명의 목적은, 동절기 외기온도의 저하로 인한 종래의 문제점이 일거에 해소될 수 있어 난방효율이 대폭 향상될 수 있도록 한 하이브리드 히트펌프식 냉난방장치를 제공하기 위한 것이다.It is an object of the present invention to provide a hybrid heat pump type heating and cooling device that can solve the conventional problems due to the decrease in the outdoor air temperature in winter so that the heating efficiency can be greatly improved.

본 발명의 또 다른 목적은, 하나의 냉난방장치에서 냉온수를 동시에 사용할 수 있고 난방히터의 열원없이도 항온항습이 가능한 하이브리드 히트펌프식 냉난방장치를 제공하기 위한 것이다.Still another object of the present invention is to provide a hybrid heat pump type heating and cooling device capable of using both hot and cold water at the same time in a single air conditioner and allowing constant temperature and humidity without a heat source of a heating heater.

본 발명에 따른 하이브리드 히트펌프식 냉난방장치에 의하면, 동절기 난방운전시에 평상시에는 냉방부하를 실외기에서 소진시키다가 외기온도가 과도하게 낮을 경우에는 응축기의 응축을 위해 소진시킴으로써 예를 들어, 압축기 과열이나 적상 등과 같은 외기온도의 저하로 인한 종래의 문제점이 일거에 해소될 수 있어 난방효율이 대폭 향상될 수 있는 탁월한 효과가 있다.According to the hybrid heat pump type air-conditioning apparatus according to the present invention, during the winter heating operation, the cooling load is normally exhausted in the outdoor unit, but when the outside air temperature is excessively low, the exhaust air is exhausted for condensation of the condenser. Conventional problems due to a drop in outside temperature, such as a drop, can be solved at once, which has an excellent effect of significantly improving heating efficiency.
또한 냉난방운전의 전환이 냉매순환관로는 동일하게 유지되는 상태에서 열매체순환관로만을 제어함으로써 이루어짐에 따라 종래에 비해 제어가 훨씬 간단용이하고 냉난방운전의 안정성이 극대화될 수 있는 탁월한 효과가 있다.In addition, since the switching of the heating and cooling operation is made by controlling only the heat medium circulation pipe in the state where the refrigerant circulation pipe is kept the same, the control is much simpler than the conventional method, and there is an excellent effect of maximizing the stability of the heating and cooling operation.
또한 지하수를 이용하여 지열이나 수폐열을 복합적으로 이용할 수 있어 그 효율을 더욱 증대시킬 수 있는 탁월한 효과가 있다.In addition, groundwater can be used in combination with geothermal heat and waste heat, which has an excellent effect of further increasing its efficiency.

뿐만 아니라 실외기가 건물 내의 보일러실, 전기제어실 또는 기계실 내에 설치될 경우에는 하절기 냉방시 실외에 쿨링타워가 설치되어야 하는 단점이 있기는 하지만 외기온도에 대한 영향이 적어 그 효율을 더욱 증대시킬 수 있는 탁월한 효과가 있다.In addition, when the outdoor unit is installed in a boiler room, electric control room or machine room in the building, there is a disadvantage that a cooling tower should be installed outdoors during summer cooling, but it is excellent in increasing the efficiency due to the low influence on the outside temperature. It works.

The rest is circulated through the condenser 80 and back to the outdoor side heat exchanger 71 of the outdoor unit 70.
이 경우에 실외기(70)의 실외측열교환기(70)로부터 토출되는 열매체의 일부는 고온열교환기(20a, 20b)를 거치면서 가열된 후 공조기(80)의 실내측열교환기(81)로 관류하게 됨에 따라 공조기(80)는 흡입된 실내공기를 실내측열교환기(81)로 가열시켜 실내로 다시 제공함으로써 실내를 난방시키게 되고, 실외기(70)의 실외측열교환기(70)로부터 토출되는 열매체의 일부는 증발기(50)와 응축기(30)를 차례로 관류한 후 다시 실외기(70)의 실외측열교환기(70)로 유입된다. In this case, a part of the heat medium discharged from the outdoor side heat exchanger 70 of the outdoor unit 70 is heated while passing through the high temperature heat exchangers 20a and 20b and then flowed through the indoor side heat exchanger 81 of the air conditioner 80. Therefore, the air conditioner 80 heats the indoors by heating the sucked indoor air with the indoor side heat exchanger 81 to provide the room back to the room, and the heat medium discharged from the outdoor side heat exchanger 70 of the outdoor unit 70. A part of the flow through the evaporator 50 and the condenser 30 in turn and then flows back to the outdoor side heat exchanger 70 of the outdoor unit 70.
특히 외기온도가 8℃ 이하에서의 난방운전시 제 1 및 제 2 개폐밸브(101 및 104)가 모두 개방되는 것이 바람직한데, 실외기(70)의 실외측열교환기(70)로부터 토출되는 열매체의 일부는 고온열교환기(20a, 20b)를 거치면서 가열된 후 공조기(80)의 실내측열교환기(81)로 관류하게 됨에 따라 공조기(80)는 흡입된 실내공기를 실내측열교환기(81)로 가열시켜 실내로 다시 제공함으로써 실내를 난방시키게 되고, 실외기(70)의 실외측열교환기(70)로부터 토출되는 열매체의 일부는 증발기(50)와 응축기(30)를 차례로 관류한 후 다시 실외기(70)의 실외측열교환기(70)로 유입됨과 동시에 응축기(30)를 관류하면서 냉매를 응축시킨 후 다시 실외기(70)의 실외측열교환기(70)로 유입된다.In particular, it is preferable that both the first and second on-off valves 101 and 104 be opened during heating operation at an outside air temperature of 8 ° C. or lower, and a part of the heat medium discharged from the outdoor side heat exchanger 70 of the outdoor unit 70 is opened. The heat is passed through the high temperature heat exchangers (20a, 20b) and then flows through the indoor side heat exchanger (81) of the air conditioner (80), the air conditioner (80) is the indoor air exchanged to the indoor side heat exchanger (81) By heating and re-providing the room, the room is heated, and a part of the heat medium discharged from the outdoor side heat exchanger 70 of the outdoor unit 70 flows through the evaporator 50 and the condenser 30 in order, and then the outdoor unit 70 again.

실내 항온항습이나 냉온수 동시사용을 하고자 하는 경우에는 제 3 유로변경밸브(115)의 유로변경으로 인해 응축기(30)를 거친 열매체가 실외기(70)로 유입되지 못하고 제 10 관로(113), 공조기(80)의 제 2 열교환기(85) 및 제 11 관로(114)를 차례로 관류하여 제 1 및 제 6 관로(91 및 98)의 분기지점으로 제공된 후 다시 순환된다. In the case of simultaneous use of indoor constant temperature and cold / hot water, the heat medium passing through the condenser 30 does not flow into the outdoor unit 70 due to the change of the flow path of the third flow path change valve 115, and thus the tenth pipe 113 and the air conditioner ( The second heat exchanger 85 and the eleventh conduit 114 of 80 are sequentially flowed through and provided to the branch points of the first and sixth conduits 91 and 98 and then circulated again.
본 발명에 따른 하이브리드 히트펌프식 냉난방장치에 의하면, 동절기 난방운전시에 평상시에는 냉방부하를 실외기에서 소진시키다가 외기온도가 과도하게 낮을 경우에는 응축기의 응축을 위해 소진시킴으로써 예를 들어, 압축기 과열이나 적상 등과 같은 외기온도의 저하로 인한 종래의 문제점이 일거에 해소될 수 있어 난방효율이 대폭 향상될 수 있는 탁월한 효과가 있다.According to the hybrid heat pump type air-conditioning apparatus according to the present invention, during the winter heating operation, the cooling load is normally exhausted in the outdoor unit, but when the outside air temperature is excessively low, the exhaust air is exhausted for condensation of the condenser. Conventional problems due to a drop in outside temperature, such as a drop, can be solved at once, which has an excellent effect of significantly improving heating efficiency.
또한 냉난방운전의 전환이 냉매순환관로는 동일하게 유지되는 상태에서 열매체순환관로만을 제어함으로써 이루어짐에 따라 종래에 비해 제어가 훨씬 간단용이하고 냉난방운전의 안정성이 극대화될 수 있는 탁월한 효과가 있다.In addition, since the switching of the heating and cooling operation is made by controlling only the heat medium circulation pipe in the state where the refrigerant circulation pipe is kept the same, the control is much simpler than the conventional method, and there is an excellent effect of maximizing the stability of the heating and cooling operation.
또한 지하수를 이용하여 지열이나 수폐열을 복합적으로 이용할 수 있어 그 효율을 더욱 증대시킬 수 있는 탁월한 효과가 있다.In addition, groundwater can be used in combination with geothermal heat and waste heat, which has an excellent effect of further increasing its efficiency.
또한 실외기 대신에 공조기의 제 2 실내측열교환기를 통해 열매체가 순환되도록 유로를 변경할 경우에는 별도의 난방히터의 열원이 없이도 실내항온항습과 냉온수 동시사용이 가능해지는 탁월한 효과가 있다.In addition, when the flow path is changed so that the heat medium is circulated through the second indoor side heat exchanger of the air conditioner instead of the outdoor unit, there is an excellent effect of enabling the simultaneous use of the room temperature and humidity and cold and hot water without a separate heat source.
뿐만 아니라 실외기가 건물 내의 보일러실, 전기제어실 또는 기계실 내에 설치될 경우에는 하절기 냉방시 실외에 쿨링타워가 설치되어야 하는 단점이 있기는 하지만 외기온도에 대한 영향이 적어 그 효율을 더욱 증대시킬 수 있는 탁월한 효과가 있다.In addition, when the outdoor unit is installed in a boiler room, electric control room or machine room in the building, there is a disadvantage that a cooling tower should be installed outdoors during summer cooling, but it is excellent in increasing the efficiency due to the low influence on the outside temperature. It works.
