본 발명은 공기흐름전환식 공기조화기에 대한 것으로서, 좀 더 상세히는 냉난방효율이 우수하면서도 설치공간을 절약할 수 있는 새로운 구조의 공기흐름전환식 공기조화기에 대한 것이다.The present invention relates to an airflow conversion type air conditioner, and more particularly, to an airflow conversion type air conditioner having a new structure capable of saving installation space while having excellent cooling and heating efficiency.

종래에 실내공기와 실외공기의 흐름방향을 응축기와 증발기로 선택적으로 절환하거나 실내공기와 실외공기를 적절한 비율로 혼합하여 응축기와 증발기로 나누어 흐르도록 하는 공기흐름전환식 공기조화기가 소개된 바 있다. 이러한 공기흐름전환을 통해서, 또는 여기에 사방밸브를 통한 냉매흐름전환방법을 결합함으로써, 단일의 응축기와 증발기를 구비한 공기조화기를 냉방과 난방을 겸할 수 있도록 하거나, 외부로 배출되는 실외공기로부터의 폐열을 실외기에서 회수하기도 하여 냉난방효율을 높이거나, 실내공기의 환기효과를 얻을 수 있다.In the related art, an airflow conversion air conditioner for selectively switching the flow direction of indoor air and outdoor air to a condenser and an evaporator, or mixing indoor air and outdoor air at an appropriate ratio and dividing it into a condenser and an evaporator has been introduced. Through this airflow switching or by combining the refrigerant flow switching method through the four-way valve, the air conditioner equipped with a single condenser and the evaporator can be combined with cooling and heating, or from the outside air discharged to the outside. Waste heat is also recovered from the outdoor unit to increase cooling and heating efficiency, or to obtain ventilation effects of indoor air.

도 1은 종래의 공기흐름전환식 공기조화기의 예를 보여주는 것인데, 도시된 바와 같이, 케이스(1)에는 실내공기 토출구(11)와 실내공기 흡입구(12) 및 실외공기 토출구(13)와 실외공기 흡입구(14)가 서로 대향하는 위치에 형성된다. 상기 실내공기 토출구(11)와 실외공기 토출구(13)는 격벽(25)에 의해 상호 구획되고, 상기 실내공기 흡입구(12)와 실외공기 흡입구(14)는 격벽(26)에 의해 상호 구획된다. 그리고, 이들 토출구(11,13) 및 흡입구(12,14) 사이에는 각각 댐퍼(31∼38)에 의해구획되는 열교환실(20)이 형성된다. 이 열교환실(20)은 다시 수평배치된 격판(21)에 의해 상하로 구획되어 상부열교환실(22)에는 증발기(2)가 배치되고, 하부열교환실(23)에는 응축기(3)가 배치된다.Figure 1 shows an example of a conventional airflow switching air conditioner, as shown, the case 1, the indoor air outlet 11 and the indoor air inlet 12 and the outdoor air outlet 13 and the outdoor Air intakes 14 are formed at positions opposite to each other. The indoor air outlet 11 and the outdoor air outlet 13 are partitioned by a partition 25, and the indoor air inlet 12 and the outdoor air inlet 14 are partitioned by a partition 26. A heat exchange chamber 20 defined by dampers 31 to 38 is formed between the discharge ports 11 and 13 and the suction ports 12 and 14, respectively. The heat exchange chamber 20 is further divided up and down by horizontally arranged diaphragms 21 so that an evaporator 2 is disposed in the upper heat exchange chamber 22 and a condenser 3 is disposed in the lower heat exchange chamber 23. .

실내공기 토출구(11)와 실외공기 토출구(13) 내에는 각각 송풍기(10a)와 송풍기(10b)가 배치된다. 번호 4는 압축기이고 번호 5는 팽창밸브이다. 이들은 냉매관(9)에 접속되어 통상적인 냉동사이클을 형성한다. 그리고, 실내외공기 흡입구(12,14)와 이에 면하는 댐퍼(33,34,35,36) 사이에는 필터(15)가 배치된다.The blower 10a and the blower 10b are disposed in the indoor air discharge port 11 and the outdoor air discharge port 13, respectively. Number 4 is the compressor and number 5 is the expansion valve. These are connected to the refrigerant pipe 9 to form a normal refrigeration cycle. In addition, the filter 15 is disposed between the indoor and outdoor air inlets 12 and 14 and the dampers 33, 34, 35, and 36 facing the indoor and outdoor air inlets 12 and 14.

이러한 공기조화기의 냉방모드에서는 실내공기루트와 증발기(2) 사이에 형성된 댐퍼(31,33)와 실외공기루트와 응축기(3) 사이에 형성된 댐퍼(36,38)를 개방하고, 나머지 댐퍼(32,34,35,37)를 닫으면, 실내공기가 증발기(2)를 거치면서 냉각되어 실내로 흐르고, 실외공기는 응축기(3)를 거치면서 가열되어 외부로 배출되어 실내의 냉방이 이루어진다. 또한, 난방모드에서는 전술한 것과 반대로, 실내공기루트와 응축기(3) 사이에 형성된 댐퍼(32,34)와 실외공기루트와 증발기(2) 사이에 형성된 댐퍼(35,37)을 개방하고, 나머지 댐퍼(31,33,36,38)를 닫으면, 실내공기는 응축기(3)를 거쳐서 가열되어 실내로 흐르고, 외부공기는 증발기(2)를 거치면서 외부로 배출되어 실내의 난방이 이루어진다.In the cooling mode of the air conditioner, the dampers 31 and 33 formed between the indoor air route and the evaporator 2 and the dampers 36 and 38 formed between the outdoor air route and the condenser 3 are opened, and the remaining dampers ( 32, 34, 35, 37, the indoor air is cooled and flows into the room while passing through the evaporator (2), the outdoor air is heated through the condenser (3) is discharged to the outside to cool the room. In addition, in the heating mode, the dampers 32 and 34 formed between the indoor air route and the condenser 3 and the dampers 35 and 37 formed between the outdoor air route and the evaporator 2 are opened in the opposite manner as described above. When the dampers 31, 33, 36, 38 are closed, the indoor air is heated through the condenser 3 to flow into the room, and the external air is discharged to the outside while passing through the evaporator 2 to heat the room.

그리고, 상기 댐퍼들(32,34,35,37)의 개방도를 적절히 조절하여 실외공기와 실내공기를 적절하게 혼합함으로써, 실내공기를 환기시킬 수 있고, 냉방모드에서의 실외측 응축기의 효율을 증대하거나 난방모드에서의 실외측 증발기의 증발효율을 증대시킴으로써 폐열회수를 통한 냉난방효율의 증대효과를 얻을 수 있다.In addition, by properly adjusting the opening degree of the dampers 32, 34, 35, 37, and mixing the outdoor air and the indoor air appropriately, the indoor air can be ventilated, and the efficiency of the outdoor condenser in the cooling mode is improved. By increasing or increasing the evaporation efficiency of the outdoor evaporator in the heating mode, it is possible to obtain the effect of increasing the heating and cooling efficiency through the waste heat recovery.

그런데, 종래의 이러한 공기조화기는 일단 케이스 내부로 유입된 실내 또는 실외공기가 댐퍼에 의해 방향이나 풍량이 조절되는 구조를 취함으로써 열교환기의 배치가 다소 복잡하여 제작이 번거롭고 설치면적을 많이 요하는 문제점이 있다. 아울러, 이들 댐퍼들이 열교환기에 근접배치된 상태에서 개개의 댐퍼가 이들 열교환기의 열교환 면적의 일부와만 겹치도록 배치되어, 자연스러운 공기흐름 상태에서 각각의 댐퍼를 거친 공기가 이들 열교환기의 열교환 면적의 일부만을 접촉하면서 통과하기 때문에 열교환 면적에 데드스페이스가 생겨서 열교환효율이 상대적으로 저하되는 문제점이 있었다. 만일 이를 막기 위해 댐퍼와 열교환기의 간격을 크게 하면 그만큼 장치의 부피가 커지는 문제점이 있었다.However, such a conventional air conditioner has a structure in which indoor or outdoor air, once introduced into a case, is controlled by a damper to control the direction or air volume, so that the arrangement of the heat exchanger is rather complicated, which makes manufacturing complicated and requires a lot of installation area. There is this. In addition, with these dampers in close proximity to the heat exchanger, the individual dampers are arranged to overlap only a portion of the heat exchange area of these heat exchangers, so that the air passing through each damper in the natural air flow condition Since only a portion passes through contact, there is a problem in that a dead space is generated in the heat exchange area so that the heat exchange efficiency is relatively lowered. If the gap between the damper and the heat exchanger is increased to prevent this, the volume of the device increases.

본 발명은 전술한 바와 같은 종래의 공기흐름전환식 공기조화기의 문제점에 착안하여 제안된 것으로서, 본 발명은 장치의 구성이 간단하여 제작이 용이하고 제작코스트가 절감되면서도 설치스페이스를 줄일 수 있는 새로운 구조의 공기흐름전환식 공기조화기를 제공하고자 하는 것이다.The present invention has been proposed in view of the problems of the conventional airflow conversion air conditioner as described above, the present invention is a simple configuration of the device is easy to manufacture and reduce the installation cost while reducing the manufacturing cost of the new It is an object of the present invention to provide a structured airflow conversion air conditioner.

또한 본 발명은 열교환기를 흐르는 공기의 흐름이 원활하면서 흐르는 공기가 열교환기의 열교환 면적에 균일하게 충분히 접촉됨으로써 열교환 효율이 우수한 새로운 구조의 공기흐름전환식 공기조화기를 제공하고자 하는 것이다.In another aspect, the present invention is to provide a new airflow conversion air conditioner having a high heat exchange efficiency by the smooth flow of the air flowing through the heat exchanger while the flowing air is in uniform contact with the heat exchange area of the heat exchanger.

이러한 구성에 따른 작동을 설명하면, 냉방모드에서는 도 3 및 도 4에 도시된 바와 같이 사방밸브(108)가 제1 열교환기(111)는 증발기로 기능하고 제2 열교환기(121)는 응축기로 기능하도록 설정되고, 댐퍼(116,117,126,127)은 적절하게 조절되어 실내공기는 제1 유입구(115)를 통해 제1 열교환실(110)의 제1열교환기(111)를 거쳐서 냉각된 후 제1 토출구(114)로 배출되고, 실외공기는 제2 유입구(125)를 통해 제2 열교환실(120)의 제2열교환기(121)를 거쳐서 가열된 후 제2 토출구(124)로 배출됨으로써 냉방작동이 수행된다. 한편 난방모드에서는 도 5 및 도 6에 도시된바와 같이, 사방밸브(108)가 반대방향으로 설정되어 제1 열교환기(111)가 응축기로 기능하고 제2 열교환기(121)가 증발기로 기능하도록 되어, 내공기는 제1 열교환기(111)에서 가열되고 실외공기는 제2 열교환기(121)에서 냉각되어 난방작동이 수행된다. 그러나 실내공기의 환기나 폐열회수 또는 냉난방 효율 개선을 위해, 실내 및 실외공기가 서로 적정비율로 혼합되어 흐를 수 있도록 댐퍼의 개방도가 적절히 조절된다. 예를 들면 실내공기와 실외공기를 30% 정도 서로 혼합되도록 댐퍼의 개방도를 설정하면, 30%의 실내공기를 환기할 수 있으며, 폐열회수를 통해 응축효율 또는 증발효율을 높일 수 있다.Referring to the operation according to this configuration, in the cooling mode, as shown in FIGS. 3 and 4, the four-way valve 108 serves as the first heat exchanger 111 as an evaporator and the second heat exchanger 121 as a condenser. The dampers 116, 117, 126, and 127 are suitably adjusted so that the indoor air is cooled through the first heat exchanger 111 of the first heat exchange chamber 110 through the first inlet 115, and then the first outlet 114. ) And the outdoor air is heated through the second heat exchanger 121 of the second heat exchange chamber 120 through the second inlet 125 and then discharged to the second outlet 124 to perform the cooling operation. . In the heating mode, as shown in FIGS. 5 and 6, the four-way valve 108 is set in the opposite direction so that the first heat exchanger 111 functions as a condenser and the second heat exchanger 121 functions as an evaporator. Thus, the internal air is heated in the first heat exchanger 111 and the outdoor air is cooled in the second heat exchanger 121 to perform a heating operation. However, in order to improve indoor air ventilation, waste heat recovery, or air-conditioning efficiency, the damper opening is appropriately adjusted so that indoor and outdoor air can be mixed with each other at an appropriate ratio. For example, if the damper is set to be mixed with indoor air and outdoor air by about 30%, 30% of indoor air can be ventilated, and condensation efficiency or evaporation efficiency can be increased through waste heat recovery.

도시된 실시예에서는 사방밸브(108)를 사용하여 냉매의 흐름을 전환시킴으로써 냉난방을 전환하는 방식을 예시하고 있으나, 본 발명은 이러한 냉매흐름방식 이외에도 순전히 공기흐름전환에 의해서만 냉난방을 전환하는 공기조화기에도 적용될 수 있다. 이를 위한 한가지 방법으로는 제1 및 제2 토출구를 실내 또는 실외로 상호 절환하여 유도하도록 케이스(100)외부에 적절한 덕트시스템을 구성하면 된다.Although the illustrated embodiment illustrates the method of switching the cooling and heating by switching the flow of the refrigerant by using the four-way valve 108, the present invention also in addition to the refrigerant flow method, the air conditioner for switching the heating and cooling only by purely air flow switching Can be applied. One way to do this is to configure a suitable duct system outside the case 100 to guide the first and second discharge port to be switched indoors or outdoors.

도 7는 본 발명의 또 다른 실시예로서, 도시된 바와 같이 두 개의 열교환실(110,120)을 병렬로 배치한 것이다. 이 실시예에 따르면, 단일의 케이스(100) 내에 종방향으로 배치된 격벽(102)에 의해 제1 열교환실(110)과 제2 열교환실(120)이 구획되고, 각각의 열교환실(110,120)에서 격벽(102)의 길이방향 일측단에는 제1 유입구(115)와 제2 유입구(125)가 각각의 열교환실(110,120)에 동시에 개방되도록 서로 인접되어 배치되고, 격벽(102)의 길이방향 타측단에는 제1 토출구(114)와 제2 토출구(124)가 서로 인접배치된 형태를 취한다. 이러한 구성에따라 제1 열교환실(110)과 제2 열교환실(120)의 각각의 유입구(115,125)로 도입된 실내 또는 실외공기는 대체로 평행하기 흘러서 각각의 열교환기(111,121)를 거친 후에 송풍기(112,122)를 통해 각각의 토출구(114,124)로 배출된다.FIG. 7 shows another heat exchange chamber 110 and 120 arranged in parallel as shown in FIG. According to this embodiment, the first heat exchange chamber 110 and the second heat exchange chamber 120 are partitioned by partitions 102 arranged in the longitudinal direction in the single case 100, and the heat exchange chambers 110 and 120 respectively. In the longitudinal one side end of the partition wall 102 is disposed adjacent to each other such that the first inlet 115 and the second inlet 125 is open to each of the heat exchange chamber (110, 120) at the same time, the longitudinal rudder of the partition (102) At the side end, the first discharge port 114 and the second discharge port 124 are disposed adjacent to each other. According to this configuration, the indoor or outdoor air introduced into the respective inlets 115 and 125 of the first heat exchange chamber 110 and the second heat exchange chamber 120 flows in parallel to each other, and passes through the respective heat exchangers 111 and 121, and then the blower ( It is discharged through the outlets 114 and 124 through the 112, 122.

한편, 히트펌프의 구조상 난방작동시에는 저온인 실외로부터 열을 흡수하여야 하고, 냉방작동시에는 고온인 실외로 열을 방출해야 하므로, 실외측 열교환기의 부하나 용량이 실내측 열교환기의 부하나 용량보다 상대적으로 클 것이 요구된다. 따라서 장치의 최적화를 위해서는 실외측 열교환기(120)의 용량을 크게 하고 실내측 열교환기(110)의 용량을 상대적으로 작게 할 필요가 있다. 따라서, 도 7에 도시된 실시예는 단순한 육면체 구조의 단일의 케이스(100)에 각각의 열교환실(110,120)을 병렬로 배치하여 그 폭을 달리함으로써, 장치의 최적화설계를 도모하면서도 장치 전체의 구조를 단순하고 균형있는 장방형 형태로 제작함으로써 설치스페이스를 줄이면서 제작코스트를 절감하게 된다.On the other hand, due to the structure of the heat pump, the heat must be absorbed from the low temperature outdoors during the heating operation and the heat must be discharged to the high temperature outdoor during the cooling operation. It is required to be relatively larger than the capacity. Therefore, in order to optimize the apparatus, it is necessary to increase the capacity of the outdoor heat exchanger 120 and relatively reduce the capacity of the indoor heat exchanger 110. Therefore, the embodiment shown in Figure 7 is arranged in a single casing 100 of a simple hexahedral structure, each heat exchange chamber (110, 120) in parallel by varying the width, thereby improving the design of the device while the overall structure of the device By manufacturing the simple and balanced rectangular shape, the manufacturing cost is reduced while reducing the installation space.

이상에서 설명한 본 발명에 따르면, 각각의 열교환실의 내부에 열교환기를 중심으로 실내외 공기 유입구(115,125)와 실내외 공기 토출구(114,124)를 대향 배치하고, 서로 인접배치된 유입구(115,125)에는 공기흐름의 방향을 절환하거나 흐름량을 조절하는 댐퍼(116,116,126,127)를 구비함으로써, 케이스 내로 유입된 실내외 공기가 열교환기에 접촉되기 전까지 원활히 흐르거나 혼합되어 열교환기에 전체 열교환면적에 충분하고 균일하게 접촉됨으로써 양호한 열교환 효율을 달성할 수 있고, 아울러 전체적으로 장치의 구조가 단순해지고 부피가 줄어 제작코스트가 절감되고 설치스페이스를 절약할 수 있다.According to the present invention described above, the indoor and outdoor air inlets 115 and 125 and the indoor and outdoor air outlets 114 and 124 are disposed to face each other inside the heat exchanger, and the inflow ports 115 and 125 disposed adjacent to each other are arranged in directions of air flow. By providing a damper (116, 116, 126, 127) to switch the flow rate or to control the flow rate, the indoor and outdoor air flowing into the case is smoothly flowed or mixed until contact with the heat exchanger to achieve a good heat exchange efficiency by sufficient and uniform contact with the entire heat exchange area to the heat exchanger In addition, the overall structure of the device is simplified, the volume is reduced, the production cost can be saved, and the installation space can be saved.

또한, 열교환실이 병렬로 배치되어 실내외 공기가 서로 평행하게 흐르는 경우에는 실내외 공기흐름이 더욱 원활하게 흘러서 열교환기 전체 면적에 균등하게 접촉될 수 있고, 또한, 상대적으로 열교환부하가 적은 실내측 열교환실의 폭을 상대적으로 작게 하면서 장치 전체를 균형있는 장방형으로 제작할 수 있어서, 최적화설계에 더욱 유리하다.In addition, when the heat exchange chambers are arranged in parallel and indoor and outdoor air flows in parallel with each other, the indoor and outdoor air flows more smoothly, so that the entire heat exchanger can be equally contacted with the entire area of the heat exchanger. The entire device can be manufactured in a balanced rectangular shape with a relatively small width, which is more advantageous for the optimization design.
