Description

실외기 없는 일체형 냉.난방기{One body type air conditioner}Integrated air conditioner without outdoor unit {One body type air conditioner}

본 발명은 실외기 없는 일체형 냉.난방기에 관한 것으로,The present invention relates to an integrated air conditioner without an outdoor unit,

특히 여름에는 실내기 자체만으로 실내냉방이 효율적으로 이루어지게 하고, 겨울철에는 석유나 히터등의 보조열원 없이 난방이 이루어지게 함으로써,In particular, in the summer, indoor cooling alone is achieved by the indoor unit itself, and in winter, heating is performed without an auxiliary heat source such as oil or a heater.

사용이 매우 편리하게 하고, 더불어 초기구입비용 및 유지비용이 최소화되게 하며, 난방시 유해가스나 매연등이 전혀 발생되지 않아 환경오염 예방에도 기여할수 있도록 하기 위한 것이다.It is very easy to use, minimizes the initial purchase cost and maintenance cost, and also contributes to the prevention of environmental pollution since no harmful gases or smoke are generated during heating.

주지된 바와같이 통상의 냉 온풍기(냉.난방기)는 실내기와 실외기로 분리 구성되어 동파이프와 전선으로 연결구성된 에어콘의 구조에 석유 또는 전기등의 보조 열원을 이용하는 장치가 추가된 구성으로서, 여름에는 일반적인 에어콘의 작용을하여 실내를 냉방시키고, 겨울철에는 석유나 전기등의 보조열원을 가동시켜 난방을 하도록 구성되어 있다.As is well known, a typical cold / heater (cooler / heater) is configured by separating an indoor unit and an outdoor unit, and adding a device using an auxiliary heat source such as petroleum or electricity to the structure of an air conditioner composed of copper pipes and wires. It acts as a general air conditioner to cool the room, and in winter it is configured to heat by running auxiliary heat sources such as oil and electricity.

또, 냉.난방기는 통상 석유등을 저장,사용할수 있어야 하기 때문에 별도의 석유탱크등이 필요하고, 이에 따라 설치공간 확보가 필수적이고, 실내기.실외기를 비롯하여 석유탱크도 구비함에 따라 설치사용시 단정하거나 깔끔한 느낌을 자아내지 못한다.In addition, air-conditioning and heating equipment usually need to store and use petroleum, so a separate petroleum tank is required. Therefore, it is necessary to secure an installation space. It does not give a neat feeling.

또한 위와 같은 냉.난방기는 겨울철 난방시, 석유 및 전기등을 이용할수 밖에 없고, 또 석유는 연소시 매연이나 유해가스가 발생하게 되므로 환경오염의 주된요인으로 작용하기도 한다.In addition, the air conditioner as described above can only use oil and electricity when heating in winter, and petroleum is a major factor in environmental pollution because smoke and harmful gas are generated during combustion.

한편, 위와 같은 냉.난방기 외에, 난방시 냉매를 역순환(증발기→응축기)시켜 콤프레샤가 냉매를 압축시킬때의 열을 이용하는 것도 있지만, 현재 사용중인 냉난방기는 실내기와 실외기로 이루어지고 실외기에 콤프레샤가 장착된 통상적인 에어콘의 구조를 이용하므로 겨울철 온도가 영하 5℃ 이하로 내려갈때는 실외기에 장착된 콤프레샤가 냉각되어 작동자체가 불가능해지기도 하였던 것이다.On the other hand, in addition to the above-mentioned air conditioners and heaters, there is a case where the compressor uses heat when the compressor compresses the refrigerant by reverse circulation (evaporator → condenser) during heating. When the temperature of the winter is lowered below minus 5 ° C., the compressor mounted on the outdoor unit is cooled and the operation itself is impossible.

또한 종래의 냉 난방기는 실내기와 실외기로 구성된 에어콘의 구조를 이용함으로써, 굵은 동파이프와 배기관, 그리고 연료(석유) 공급호스등을 연결구성하여야 하므로 설치에 따른 시간과 인력이 과다소요되고, 또 동파이프와 배기관, 그리고 연료공급호스의 노출로 인하여 외관이 단정하지 못한 결점도 따랐던 것이다.In addition, the conventional cold heater uses a structure of an air conditioner composed of an indoor unit and an outdoor unit, so that a thick copper pipe, an exhaust pipe, and a fuel (petroleum) supply hose must be connected to each other, which requires excessive time and manpower according to the installation. Exposure to pipes, exhaust pipes, and fuel hoses was also an unsightly flaw.

또,(여름철 냉방시) 건물의 구조나 주변상황에 의해 실내기와 실외기의 거리가 제법 떨어지는 경우도 많은데, 실내기와 실외기가 동파이프로 연결설치되고 상기 동파이프를 통하여 냉매가 순환되면서 냉각되는 구성이기에,In addition, the distance between the indoor unit and the outdoor unit is quite low due to the structure of the building or the surrounding conditions (in summer cooling), since the indoor unit and the outdoor unit are connected to the copper pipes, and the refrigerant is circulated and cooled through the copper pipes. ,

실내기와 실외기의 거리가 멀 경우, 냉방 효율이 크게 떨어지는 문제점도 따르게 되며, 실외기를 통하여 냉매냉각이 이루어지기 때문에 외부의 기온이 지나치게 높을 경우 냉매 냉각 효율도 크게 떨어져 실내냉방에 한계를 느낄수 밖에 없게 되는 문제점도 따르게 된다.When the distance between the indoor unit and the outdoor unit is far, there is a problem that the cooling efficiency is greatly reduced. Since the cooling of the refrigerant is performed through the outdoor unit, when the outside temperature is too high, the cooling efficiency of the refrigerant is also greatly reduced, resulting in a limitation in indoor cooling. Problems also follow.

따라서 본 발명은 전술한 종래 냉.난방기에 따른 제반문제점을 감안하여 안출된 것으로, 특히 실내기 자체로 냉매의 냉기발산(증발)과 냉매 냉각이 모두 이루어지게 하여 실외기가 없는 구성이면서도 실내냉방 효율이 극대화되게 하고, 또 난방시에는 냉매를 역순환시켜 석유와 같은 별도의 보조열원 없이 효율적인 난방이 이루어지게 끔 함으로써, 실내기 한대로서 냉.난방이 이루어지게 끔 하려는데 그 목적이 있는 것이다.Therefore, the present invention has been devised in view of the above-mentioned problems according to the conventional air conditioners and air conditioners, and in particular, the indoor unit itself makes both cooling and cooling (evaporation) and cooling of the refrigerant, thereby maximizing indoor cooling efficiency even without the outdoor unit. In addition, when heating, the refrigerant is reversely circulated so that efficient heating is performed without a separate auxiliary heat source such as petroleum, so that the cooling and heating is performed as one indoor unit.

또 증발기(21)와 콤프레샤(51) 사이에 회수관(53)을 설치하여 증발기(21)를 순환한 후 나오는 냉매의 회수가 원활하게 이루어지게 하되, 상기 회수관(53)은 4웨이밸브(200)에 형성된 C부분과 연결되게 하고, 4웨이밸브(200)의 D부분은 또다른 회수관(53')과 연결되면서 콤프레샤(51)와 연결되게 하였다.In addition, a recovery pipe 53 is installed between the evaporator 21 and the compressor 51 to smoothly recover the refrigerant coming out after circulating the evaporator 21, but the recovery pipe 53 is a four-way valve ( It is connected to the C portion formed in the 200, and the D portion of the four-way valve 200 is connected to the compressor 51 while being connected to another recovery pipe (53 ').

한편, 냉매공급관(52')을 통하여 증발기(21)로 공급되는 냉매를 효과적으로 냉각시켜주기 위해 설치된 냉각콘덴서(31)와 과냉각장치(61)의 구조를 살펴보면, 냉각콘덴서(31)의 경우 케이스(311) 외주면에 다수의 통공부(312)를 형성하고 내부에는 다단으로 열교환기(32)를 설치하며, 상면에 송출휀(313)을 설치하여 구성하되, 이는 송출휀(313)이 작동하면서 동체배면하측에 설치된 흡입구멍(324)을 통하여 실내의 공기가 강제유입되게 하고, 유입된 공기가 통공부(312)를 통하여 케이스(311) 내부로 유입되면서 열교환기(32)를 냉각시켜 준후, 상기 송출휀(313)과 연결설치된 배출관(314)을 통하여 실외로 배출되게 하며, 더불어(후술하는) 물탱크(41)의 물이 펌프(42)에 의해 분무노즐(43)을 통하여 열교환기(32)에 안개처럼 분무되게 하여 공냉 및 수냉방식 겸용으로 냉각이 더욱 효과적으로 이루어지게 한다.On the other hand, the structure of the cooling capacitor 31 and the supercooling device 61 installed to effectively cool the refrigerant supplied to the evaporator 21 through the refrigerant supply pipe 52 ', the case of the cooling capacitor 31 311) A plurality of through-holes 312 are formed on the outer circumferential surface, and the heat exchanger 32 is installed in multiple stages inside, and the discharge fan 313 is installed on the upper surface, which is configured while the discharge fan 313 operates. Through the suction hole 324 installed on the rear side to force the air in the room, and the introduced air is introduced into the case 311 through the through-hole 312 to cool the heat exchanger 32, and then It is discharged to the outside through the discharge pipe 314 connected to the discharge fan 313, and the water of the water tank 41 (to be described later) through the spray nozzle 43 by the pump 42, the heat exchanger 32 ) So that it is sprayed like a mist on the air Innovation must be done efficiently.

이어서 냉각콘덴서(31)에서 1차 냉각된 냉매는 과냉각장치(61)에서 2차냉각되는데, 상기 과냉각 장치(61)는 이중관으로 형성되어 중심관 부분으로는 1차냉각된 냉매가 통과하고, 외부관에는 정수장치(44)에서 퇴수되는 물이 통과되게 하여 냉매가 더욱 안정적으로 냉각되게 한다.Subsequently, the first coolant cooled by the cooling capacitor 31 is secondly cooled by the supercooling device 61. The supercooling device 61 is formed of a double pipe so that the first coolant passes through the center pipe part. The pipe allows the water discharged from the water purifier 44 to pass through, thereby allowing the refrigerant to be cooled more stably.

물탱크(41)는 증발기(21)에서 형성된 응축수와 냉각콘덴서(31)에서 배출되는 퇴수, 그리고 상수도물〈정수장치(44)를 통하여 정수된 물〉이 응축수 배출관(211)과 퇴수관(212), 그리고 급수관(213)을 통하여 공급되고, 물탱크(41)와 펌프(42) 사이의 공급관에 여과기(45)를 설치하여 열교환기에 안정적으로 물을 분무할수 있도록 한다.The water tank 41 is a condensate formed in the evaporator 21 and the discharged water discharged from the cooling capacitor 31, and tap water (water purified through the water purifier 44) is a condensate discharge pipe 211 and the discharge pipe 212 And, it is supplied through the water supply pipe 213, the filter 45 is installed in the supply pipe between the water tank 41 and the pump 42 to be able to spray water to the heat exchanger stably.

미설명부호 100은 휠터, 101은 응축수 받이, 102는 송풍그릴이다.Reference numeral 100 denotes a filter, 101 a condensate receiver, and 102 a blower grill.

이와 같이 구성된 본 발명의 작용을 설명한다.The operation of the present invention configured as described above will be described.

본 발명의 구성은 실내기 만으로 냉방과 난방을 겸용할수 있다.The configuration of the present invention can be used for both cooling and heating only indoor unit.

즉, 냉방시에는 콤프레샤(51)에 의해 냉매가 증발기(21)로 공급될때(종래 실 외기가 있는 에어콘에서는 냉매가 실외기로 돌아나오면서 냉각되었음) 냉매공급관(52)(52')와 4웨이밸브(200)의 b부분을 통하여 냉각콘덴서(31)를 통과하는 과정에서 송출휀(313)이 작동하여 실내공기를 케이스(311)의 통공부(312)를 통하여 빨아들이게 되고, 이때 빨아들인 공기는 열교환기(32)를 냉각시키면서 배출관(314)으로 배출되며, 이와 동시에 물탱크(41)의 물이 여과기(45)를 거쳐 펌프(42)에 의해 냉각콘덴서(31)내로 안개처럼 분무되면서 열교환기(32)를 냉각시켜 줌으로써 물과 공기에 의해 냉매가 1차냉각되는 것이며, 1차냉각된 냉매는 첵크밸브(400)를 거쳐 과냉각장치(61)를 통과하면서 정수장치(61)에서 퇴수되는 물에 의해 2차냉각시켜주는 것이다.That is, during cooling, when the refrigerant is supplied to the evaporator 21 by the compressor 51 (in the conventional air conditioner, the refrigerant is cooled by returning to the outdoor unit) and the refrigerant supply pipes 52 and 52 '. In the process of passing the cooling capacitor 31 through the b portion of the 200, the discharge fan 313 is operated to suck the indoor air through the through-hole 312 of the case 311, wherein the sucked air is While cooling the heat exchanger (32) is discharged to the discharge pipe 314, at the same time the water of the water tank 41 is sprayed like a mist into the cooling capacitor 31 by the pump 42 through the filter 45, the heat exchanger By cooling the 32, the refrigerant is first cooled by water and air, and the refrigerant cooled by the water is discharged from the water purification device 61 while passing through the supercooling device 61 through the check valve 400. By secondary cooling.

또 과냉각장치(61)를 통과한 냉매는 모세관(71)을 통하여 증발기(21)로 공급되고 냉매를 냉각시킨 물은 호스등을 연결하여 외부로 퇴수시켜주면 된다.In addition, the refrigerant passing through the supercooling device 61 is supplied to the evaporator 21 through the capillary tube 71, and the water cooling the refrigerant may be discharged to the outside by connecting a hose or the like.

또한 증발기(21)를 통과한 냉매는 회수관(53)을 통하여 4웨이밸브(200)의 C부분을 거친후 콤프레샤(511)로 회수되고, 회수된 냉매는 다시 4웨이밸브(200)의 b부분을 통하여 공급되므로, 냉매가 실내기 내에서 순환되는 것이며, 냉매 냉각 방식을 공냉 및 수냉방식을 함께 적용하여 냉매 냉각을 시킴에 따라 오히려 실외기를 통하여 냉매 냉각을 시키는 것보다 냉방효율을 크게 향상시켜줄수 있게 되는 것이다.In addition, the refrigerant passing through the evaporator 21 passes through the C portion of the four-way valve 200 through the recovery pipe 53 and is recovered to the compressor 511, the recovered refrigerant is again b of the four-way valve 200 Since it is supplied through the part, the refrigerant is circulated in the indoor unit. By applying the refrigerant cooling method together with the air cooling and water cooling methods to cool the refrigerant, rather than cooling the refrigerant through the outdoor unit, the cooling efficiency can be greatly improved. Will be.

한편, 본 발명에서 냉매 냉각을 위해 사용하는 냉각수는 크게 상수도물과 응축수를 사용하게 되는데, 상수도물의 경우는 염소등을 비롯한 각종 약품과 세균, 그리고 기타 이물질이 함유되어 있으므로 그대로 사용할 경우 냉각수가 통하는 관이나 기타 수분이 닿는 부품등에 녹이나 스케일등이 발생할 염려가 있으므로 별도의 정수장치(44)를 통과하여 물탱크(41)로 공급시키고, 상기 물탱크(41)이 물을 냉각콘덴서(31)로 공급하여 분무시킬때도 미리 여과기(45)를 통과시킴으로써 내구성증대와 안정적인 냉각작용이 이루어지게 되는 것이다.On the other hand, the cooling water used for cooling the refrigerant in the present invention is largely used tap water and condensate, in the case of tap water contains various chemicals, such as chlorine and bacteria, and other foreign substances, if used as it is a pipe through which the coolant passes Since there is a risk of rust or scale, etc. in contact with water or other moisture, the water tank 41 is supplied to the water tank 41 through a separate water purifier 44, and the water tank 41 supplies water to the cooling capacitor 31. When supplying and spraying is also through the filter 45 in advance to increase the durability and stable cooling will be made.

그리고, 부수적인 작용이기는 하지만, 물탱크(41)내의 수위감지를 위한 수위 감지호스(411)를 투명 또는 반투명으로 설치사용하여 물탱크(41)내의 수위감지가 항상 가능하게 하였고, 또 온도감지센서(412)를 설치하여 실내온도측정이 가능하게 하였다.And, although it is a side effect, the water level detection hose 411 for water level detection in the water tank 41 is installed or used transparently or semi-transparent, so that the water level detection in the water tank 41 is always possible, and the temperature sensor 412 was installed to allow room temperature measurements.

한편 난방시에는 4웨이밸브(200)를 역조작시켜(이때 4웨이밸브는 a부분과 c부분이 연통되게 되고, D부분과 b부분이 연통됨) 냉매가 회수관(53)을 통하여 증발기(21)로 유입 순환되게 한후 모세관(71)을 거쳐 냉매공급관(52')으로 회수되게 하되, 상기 회수관(53)에 설치된 과냉각장치(61)가 역으로 냉매를 가열하는 장치로서의 작용을 하게 하고, 이어서 과냉각장치(61)를 통하여 회수되는 냉매를 다시 모세관(300)을 통과시킨 다음 냉각콘덴서(31)로 공급시키면 냉각콘덴서(31)가 이 경우에는 오히려 냉매를 상온으로 가열시키는 작용을 하게 되며, 상온으로 가열된 냉매는 4웨이밸브(200)의 b부분을 거쳐 D부분으로 인출되어 콤프레샤(51)로 회수되게 되는 것이다.On the other hand, during heating, the four-way valve 200 is reversely operated (in this case, the four-way valve is in communication with the a part and the c part, and the D part and the b part are in communication) and the refrigerant is evaporated through the recovery pipe 53. 21) and then to the refrigerant supply pipe 52 'through the capillary tube 71, the subcooling device 61 installed in the recovery pipe 53 acts as a device for heating the refrigerant in reverse. Subsequently, the refrigerant recovered through the subcooling device 61 passes through the capillary tube 300 again, and then is supplied to the cooling capacitor 31 so that the cooling capacitor 31 heats the refrigerant to room temperature in this case. , The refrigerant heated to room temperature is withdrawn to the compressor 51 through the b portion of the four-way valve 200 to the D portion.

즉, 난방시에는 냉매의 흐름을 역류시켜 냉방시에 증발기를 거친후 회수되는 냉매가 뜨거워지게 되는 원리를 역이용함으로써 석유등의 보조열원 없이 실내에 안정적으로 열풍을 방출시킬수 있게 하였다는 것이며, 이러한 작용이 가능하게 되는 이유는 4웨이밸브(200)와 첵크밸브(400)를 비롯하여 종래처럼 냉매가 실외기를 거쳐 냉각되는 구성이 아니고 실내기 내에서 순환되게 끔 한 구성이기에 가능해진다 하겠다.In other words, by reversing the flow of the refrigerant during heating, the refrigerant recovered after passing through the evaporator during heating becomes hot, allowing the hot air to be stably released to the room without an auxiliary heat source such as petroleum. The reason for this is to be possible because it is a configuration such that the refrigerant is circulated in the indoor unit, rather than the configuration that the refrigerant is cooled through the outdoor unit as in the prior art, including the four-way valve 200 and the check valve 400.

이상 설명한 바와 같이 본 발명은 실외기 없이 실내기만으로 냉.난방이 이루어지는 구성으로서, 설치가 손쉽고 유지, 보수, 관리가 손쉬움은 물론 외기의 영향을 받지 않고 냉.난방을 할수 있어 냉방 및 난방 효율을 극대화시킬수 있게 된다.As described above, the present invention is a configuration in which cooling and heating are performed only by an indoor unit without an outdoor unit, and is easy to install, easy to maintain, repair, and manage, and can be cooled and heated without being influenced by outside air, thereby maximizing cooling and heating efficiency. Will be.

또한 냉각수를 순환시킴에 있어서, 정수장치와 여과기를 이용하여 순환시켜 냉매를 냉각시킴으로써 냉각수 순환관 및 부품들의 수명을 장구하게 연장시킬수 있게 되며, 첵크밸브(400)와 4웨이밸브(200)에 의해 히터나 석유등과 같은 보조열원 없이 난방도 할수 있어 난방비 절감, 공해예방, 전력절감등의 효과가 뛰어난 매우 유용한 매우 유용한 발명인 것이다.In addition, in circulating the cooling water, the refrigerant is circulated by using a water purifier and a filter to cool the refrigerant, thereby prolonging the life of the cooling water circulation pipe and parts, and by the check valve 400 and the 4-way valve 200. It can be heated without an auxiliary heat source such as a heater or petroleum, so it is a very useful invention with excellent effects such as heating cost reduction, pollution prevention, and power saving.
