공기흐름전환식 냉난방겸용 공기조화기{Air flow switching type air conditioner for both cooling and heating}Air flow switching type air conditioner for both cooling and heating

본 발명은 공기흐름전환식 냉난방겸용 공기조화기에 대한 것으로서, 좀 더 상세히는 실내외공기의 흐름을 선택적으로 증발기 또는 응축기를 거치도록 전환시킴으로써 효율좋게 냉난방기능을 겸할 수 있으며, 아울러 간단한 구조로서 항온항습기를 겸할 수 있도록 한 새로운 구조의 냉난방겸용 공기조화기에 대한 것이다.The present invention relates to an airflow switching air-conditioning combined air conditioner, and more specifically, by switching the flow of indoor and outdoor air to selectively pass through an evaporator or a condenser, and has an efficient heating and cooling function, and also a simple temperature and humidity controller as a simple structure. It is a new air conditioning and air conditioner with a new structure.

종래의 냉난방겸용 공기조화기는 냉방용 냉매싸이클과 히터를 겸비한 구조이거나, 실외측 열교환기와 실내측 열교환기를 구비하고 방향전환밸브를 이용하여 냉매의 흐름을 전환시켜서 냉방시에는 실내측 열교환기가 증발기로 작동하도록 하여 실내의 열을 흡수하고, 난방시에는 실내측 열교환기가 응축기로 작동하도록 하여 실내에 열을 방출하도록 한 이른바 열펌프식 구조가 열려져 있다. 그러나, 이러한 종래의 냉난방겸용 공기조화기는 상대적으로 그 구조가 복잡한 반면, 냉난방효율은 낮아서 제작 및 유지비가 많이 드는 문제점이 있었다.Conventional air-conditioning combined air conditioner has a cooling refrigerant cycle and a heater, or an outdoor heat exchanger and an indoor heat exchanger, and uses a directional valve to switch the refrigerant flow to operate the indoor heat exchanger as an evaporator. The so-called heat pump type structure, which absorbs heat in the room and heats the room by allowing the indoor heat exchanger to operate as a condenser during heating, is opened. However, such a conventional air-conditioning and combined air conditioner has a relatively complicated structure, while the cooling and heating efficiency is low, there is a problem that the manufacturing and maintenance costs are high.

본 발명은 전술한 바와같은 종래의 냉난방기기의 문제점에 착안하여 제안된 것으로서, 간단한 냉매싸이클 구조에서 실내외 공기의 흐름방향만을 제어함으로써 냉방과 난방기능을 수행할 수 있는 새로운 방식의 냉난방겸용 공기조화기를 제공하고자 하는 것이다.The present invention has been proposed in view of the problems of the conventional air-conditioning apparatus as described above, and a new air-conditioning combined air conditioner capable of performing cooling and heating functions by controlling only the flow direction of indoor and outdoor air in a simple refrigerant cycle structure. It is to provide.

또한, 본 발명은 실내공기의 환기기능을 구비하여 환기시 배기 속의 에너지를 전량 회수하고, 실내의 온도와 습도를 정밀하게 제어 또는 유지할 수 있는 새로운 구조의 냉난방겸용 공기조화기를 제공하고자 하는 것이다.In addition, the present invention is to provide a new air-conditioning and air conditioner of a new structure that has a ventilation function of the indoor air to recover the total amount of energy in the exhaust during ventilation, and to accurately control or maintain the temperature and humidity of the room.

실내측토출구(11) 내에는 블로워(10a)가 배치되고, 실외측토출구(13) 내에는 또다른 블로워(10b)가 배치된다. 번호 4는 압축기이고 번호 5는 팽창밸브로서, 소용량인 경우에는 캐필러리튜브로 대체할 수 있다. 이들은 냉매관(9)에 접속되어 통상적인 냉동사이클을 형성한다. 그리고, 실내외측 흡입구(12,14)와 이에 면하는 댐퍼(33,34,35,36) 사이에는 필터(15)가 배치된다. 상기 압축기(4)는 용량에 따라 케이스(1) 외부에 설치될 수 있다.A blower 10a is disposed in the indoor side discharge port 11, and another blower 10b is disposed in the outdoor side discharge port 13.

The compressor 4 may be installed outside the case 1 according to the capacity.

이러한 구성을 취하는 본발명의 냉방모드에서의 작동을 도 2를 참조하여 설명한다. 여기서 점선으로 표시된 공기흐름루트는 격판(21) 밑으로 응축기(3)를 통과하는 공기흐름을 표시한다.Operation in the cooling mode of the present invention having such a configuration will be described with reference to FIG. Here, the air flow route indicated by the dotted line indicates the air flow passing through the condenser 3 under the diaphragm 21.

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, 증발기(2)를 거쳐서 냉각된 실내공기는 실내공기토출구(11)를 통해 실내로 흐르고, 실내에서 가온된 공기는 실내공기흡입구(12)를 통해 증발기(2)로 흐르게 된다. 한편, 실외공기흡입구(14)를 통해 유입된 외부공기는 응축기(3)를 거치면서 열을 흡수하여 실외공기토출구(13)를 통해 외부로 배출되어 실내의 냉방이 이루어진다.The dampers 31, 33 formed between the indoor air route and the evaporator 2 and the dampers 36, 38 formed between the outdoor air route and the condenser 3 are opened, and the remaining dampers 32, 34, 35, 37 are opened. When closed, the indoor air cooled through the evaporator 2 flows into the room through the indoor air discharge port 11, and the air heated in the room flows to the evaporator 2 through the indoor air suction port 12. On the other hand, the outside air introduced through the outdoor air suction port 14 absorbs heat while passing through the condenser 3 and is discharged to the outside through the outdoor air discharge port 13 to cool the room.

이러한 냉방모드의 경우에, 만일 개방되는 댐퍼(31,33,36,38)의 개도를 70%정도로 하고 닫히는 댐퍼(32,34,35,37)의 개도를 30%로 한다면, 70%의 차가운 실내공기와 환기를 위한 30%의 더운 실외공기가 증발기(2)를 통과하면서 열이 제거되어 냉각된 혼합공기가 실내로 공급된다. 이때, 증발기(2)에서는 응축수가 다량 발생하여 응축기(3)에 살포됨으로써 응축기의 효율이 개선된다. 즉, 응축기는 공냉과 수냉을 겸하게 된다. 또한, 70%의 더운 실외공기와 환기를 위한 30%의 차가운 실내공기가 혼합되어 온도가 하강된 혼합공기가 응축기(3)를 통과함으로써 응축기(3)로부터 열을 흡수하는 응축효율이 증대된다.In the case of such a cooling mode, if the opening degree of the dampers 31, 33, 36, 38 is set to about 70% and the opening degree of the closing dampers 32, 34, 35, 37 is set to 30%, 70% of the cold As 30% of the hot outdoor air for indoor air and ventilation passes through the evaporator 2, heat is removed and cooled mixed air is supplied to the room. At this time, in the evaporator 2, a large amount of condensed water is generated and sprayed on the condenser 3 to improve the efficiency of the condenser. That is, the condenser combines air cooling and water cooling. In addition, the condensation efficiency of absorbing heat from the condenser 3 is increased by mixing 70% of hot outdoor air with 30% of cold indoor air for ventilation and passing the condenser 3 through which the temperature is lowered.

도 3을 참조하여 본 발명의 난방모드를 설명하면, 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)을 닫으면, 응축기(3)를 거쳐서 가온된 실내공기는 실내공기토출구(11)를 통해 실내로 흐르고, 다시 실내공기흡입구(12)를 통해 응축기(3)로 흐르게 된다. 한편, 실외공기흡입구(14)를 통해 유입된 차가운 외부공기는 증발기(2)를 거치면서 열을 빼앗긴 후 실외공기토출구(13)를 통해 외부로 배출되어 실내의 난방이 이루어진다.Referring to FIG. 3, the heating mode according to the present invention will be described. In contrast to the above, the dampers 32 and 34 formed between the indoor air route and the condenser 3 and the dampers formed between the outdoor air route and the evaporator 2 ( 35, 37 and the remaining dampers 31, 33, 36, 38 are closed, the indoor air heated through the condenser 3 flows to the room through the indoor air discharge port 11, and again the indoor air intake port ( 12) to the condenser (3). On the other hand, the cold outside air introduced through the outdoor air suction port 14 is deprived of heat while passing through the evaporator (2) is discharged to the outside through the outdoor air discharge port 13 is made to heat the room.

이러한 난방모드의 경우에, 만일 개방되는 댐퍼(32,34,35,37)의 개도를 70%정도로 하고 닫히는 댐퍼(31,33,36,38)의 개도를 30%로 한다면, 70%의 따뜻한 실내공기와 환기를 위한 30%의 차가운 실외공기가 응축기(3)를 통과하면서 가열되어 가온된 혼합공기가 실내로 공급된다. 그리고, 70%의 차가운 실외공기와 환기를 위한 30%의 더운 실내공기가 혼합되어 온도가 상승된 혼합공기가 증발기(2)를 통과함으로써 증발기(2)가 열을 빼앗는 증발효율이 증대된다.In this heating mode, if the dampers 32, 34, 35, 37 are opened at about 70% and the dampers 31, 33, 36, 38 are opened at 30%, 70% warm 30% of cold outdoor air for indoor air and ventilation is passed through the condenser (3) to supply heated mixed air to the room. In addition, 70% of cold outdoor air and 30% of hot indoor air for ventilation are mixed to increase the evaporation efficiency of the evaporator 2.

도 4와 도 5를 참조하여 본 발명의 또다른 실시예를 설명한다. 도시된 바와같이, 실내(R)에는 습도센서(7)가 구비되고, 실내공기토출구(11)와 증발기(2) 사이에는 재열기(6)가 부설된다. 이 재열기(6)는 도 5에 도시된 바와같이, 응측기(3)와 팽창밸브(5) 사이에 접속된 보조응축기이다. 또한, 상기 실내공기토출구(11)와 응축기(3) 사이에는 가습기(8)가 부설된다.Another embodiment of the present invention will be described with reference to FIGS. 4 and 5.

이러한 구성에 따라, 냉방모드에서 현재 실내의 상대습도의 변화를 습도센서(7)가 검출하여 실외측 토출구(13)에 형성된 응축기 블로워(10b)의 풍량을 제어하여 응축기(3)로부터의 열방출량을 조절하게 된다. 이에따라 응축기(3)의 후단에 접속된 재열기(6)로 흐르는 열이 가감되어, 이 재열기(6)로부터의 방출열에 의해 증발기(2)를 거쳐 실내공기토출구(11)로 나오는 공기의 온도를 적절히 제어함으로써 실내의 상대습도를 조절하게 된다. 이때 재열량이 증가될수록 냉동능력의 증가가 요구되나, 재열량의 증가만큼 팽창밸브(5)로 유입되는 냉매가 과냉각되어 냉동능력이 증가되므로 재열로 인해 냉동능력이 저하되는 문제가 없게 된다. 만일 실내의 상대습도가 목표치보다 낮은 경우에는 정상적인 냉방작동을 통해 실내의 상대습도를 높이면 된다.According to this configuration, the humidity sensor 7 detects the change in the relative humidity of the current room in the cooling mode, and controls the air volume of the condenser blower 10b formed in the outdoor side discharge port 13 to control the amount of heat released from the condenser 3. Will be adjusted. Accordingly, the heat flowing to the reheater 6 connected to the rear end of the condenser 3 is subtracted, and the temperature of the air exiting the indoor air discharge port 11 through the evaporator 2 by the heat of release from the reheater 6. By appropriately controlling the relative humidity of the room is adjusted. At this time, as the amount of reheat is increased, an increase in refrigerating capacity is required, but as the amount of reheat is increased, the refrigerant flowing into the expansion valve 5 is supercooled and the refrigerating capacity is increased so that the refrigerating capacity is not degraded by reheating. If the relative humidity in the room is lower than the target value, increase the relative humidity in the room through normal cooling operation.

또한, 난방모드에서 실내의 상대습도가 목표치보다 낮은 것을 습도센서(7)가 검출하면, 가습기(8)를 작동하여 응축기(3)를 통해 실내공기토출구(11)로 나오는 공기에 습기를 증가시킨다. 만일 실내의 상대습도가 목표치보다 높은 경우에는 정상적인 난방작동을 통해 실내의 상대습도를 낮추면 된다.In addition, when the humidity sensor 7 detects that the relative humidity of the room is lower than the target value in the heating mode, the humidifier 8 is operated to increase moisture in the air exiting the indoor air outlet 11 through the condenser 3. . If the relative humidity in the room is higher than the target, lower the relative humidity in the room through normal heating.

전술한 바와같은 댐퍼(31∼38)의 개도조절 및 재열기(6)와 가습기(8)의 작동이나 블로워(10a,10b)의 풍량 등은 실내의 습도를 검출하는 습도센서(7)와 설명이 생략된 온도센서 및 사용자가 임의로 입력하는 설정치에 따라 도시안된 콘트롤러에 의해 수행됨은 물론이다. 번호 46은 습도조절기로서 콘트롤러의 일부를 구성하거나 별도로 구비될 수 있다.As described above, the opening degree control of the dampers 31 to 38, the operation of the reheater 6 and the humidifier 8, the air volume of the blowers 10a and 10b, and the like are explained with the humidity sensor 7 for detecting the humidity in the room. It is of course performed by the controller not shown in accordance with the omitted temperature sensor and the user's arbitrarily set values. No. 46 is a hygrostat which may form part of the controller or be provided separately.

도 6은 본 발명의 변형예가 난방모드에서 작동되는 동작상태도이다. 이를 참조하면, 상기 실외측흡입구(14)와 응축기(3) 사이에는 응축기(3)와 증발기(2) 사이의 냉매관(9)에 연결된 보조응축기(3a)가 설치된다. 이때, 상기 응축기(3)를 통과하여 보조응축기(3a)로 유입되는 고압의 냉매는 잔류 열량에 의해 그 온도가 약 40℃에 달하기 때문에 이를 이용하여 외기의 온도를 예열할 수 있게 된다.6 is an operational state diagram in which the modified example of the present invention operates in the heating mode. Referring to this, an auxiliary condenser 3a connected to the refrigerant pipe 9 between the condenser 3 and the evaporator 2 is installed between the outdoor side suction port 14 and the condenser 3. At this time, the high-pressure refrigerant flowing through the condenser 3 into the auxiliary condenser 3a reaches a temperature of about 40 ° C. due to the amount of residual heat, so that the temperature of the outside air can be preheated using the refrigerant.

이상의 구성에 따라, 개방되는 댐퍼(32,34,35,37)의 개도를 70%정도로 하고 닫히는 댐퍼(31,33,36,38)의 개도를 30%로 한다면, 환기를 위한 30%의 차가운 공기가 보조응축기(3a)를 통과하면서 예열된 상태로 유입되고, 이는 실내공기흡입구(12)를 통해 유입되는 70%의 따뜻한 실내공기와 혼합되어 응축기(3)를 통과하면서 가열되어 가온된 혼합공기가 실내로 공급된다. 그리고, 70%의 차가운 실외공기와 환기를 위한 30%의 더운 실내공기가 혼합되어 온도가 상승된 혼합공기가 증발기(2)를 통과함으로써 증발기(2)가 열을 빼앗는 증발효율이 증대된다. 또한, 환기를 위해 실내로 유입되는 차가운 외기의 온도가 보조응축기(3a)를 통과하면서 예열된 후 증발기(3)로 유입되어 가온되기 때문에 그 만큼 난방효율이 증대된다.According to the above configuration, if the opening degree of the dampers 32, 34, 35 and 37 is set to about 70% and the opening degree of the dampers 31, 33, 36 and 38 to be closed is 30%, 30% of the cold for ventilation Air enters the preheated state as it passes through the auxiliary condenser (3a), which is mixed with 70% of warm indoor air introduced through the indoor air intake (12) and heated and warmed while passing through the condenser (3). Is fed into the room. In addition, 70% of cold outdoor air and 30% of hot indoor air for ventilation are mixed to increase the evaporation efficiency of the evaporator 2. In addition, since the temperature of the cold outside air introduced into the room for ventilation is preheated while passing through the auxiliary condenser 3a, the heating efficiency is increased by the temperature of the cold outside air.

이상에서 설명한 본 발명에 따르면, 통상적인 냉매싸이클로 이루어진 간단한 구조의 장치로서 실내외공기의 유출입량을 선택적으로 개폐하거나 개도를 조절하여 공기의 흐름방향과 흐름량을 조절함으로써 냉방과 난방을 겸할 수 있고 냉난방효율이 우수한 새로운 구조의 냉난방겸용 공기조화기를 제공할 수 있다. 또한, 통상적인 냉매싸이클에 부설된 재열기와 가습장치를 통해 별도의 장치없이도 실내의 온도와 습도를 정밀하게 제어유지할 수 있는 탁월한 냉난방겸용 공기조화기가 제공되게 된다.According to the present invention described above, as a simple structure of the device consisting of a conventional refrigerant cycle by controlling the air flow direction and flow rate by selectively opening or closing the flow rate of the indoor and outdoor air or by adjusting the opening degree, the cooling and heating efficiency is It is possible to provide an excellent air conditioning and air conditioning unit with a new structure.
