In the heating operation, the high temperature high pressure refrigerant gas compressed in the compressor flows through a bypass pipe(101) while heating the water flowing through the hot water heat exchanger. The heated water emits radiant heat while circulating through a radiant heat generating unit(104). Therefore, a room is heated by convection and radiation heating.

Description

공기 조화기 {AIR CONDITIONER}Air conditioner {AIR CONDITIONER}

본 발명은 공기 조화기에 관한 것이며, 상세하게는 히트 펌프를 이용한 공기 조화기에 관한 것이다.The present invention relates to an air conditioner, and more particularly, to an air conditioner using a heat pump.

주지하는 바와 같이 히트 펌프를 이용한 공기 조화기는 압축기, 4방밸브, 실내 열교환기, 팽창밸브, 실외 열교환기 및 상기 4방밸브를 도관으로 순서대로 연결하고, 상기 4방밸브와 압축기를 흡입도관으로 연결하여서 된 것이다.As is well known, an air conditioner using a heat pump connects a compressor, a four-way valve, an indoor heat exchanger, an expansion valve, an outdoor heat exchanger, and the four-way valve in order with a conduit, and connects the four-way valve and the compressor with a suction conduit. It was made by connecting.

상기한 공기 조화기는 난방운전시에는 4방밸브를 냉매가 실내 열교환기 측으로 흐르도록 조작하여 압축기에서 압축된 고온·고압의 냉매가스를 응축기로 작용하는 실내 열교환기에 흐르도록 하여 그 응축열을 실내공기와 열교환시키므로서 공기 조화실내를 난방하고, 실내 열교환기에서 응축된 고온·고압의 냉매액을 팽창밸브에서 팽창시킨 후 증발기로 작용하는 실외 열교환기에서 외기를 열원으로 하여 증발시켜 저온·저압의 가스상태가 되게 한 후 압축기에 흡입되는 사이클을 반복하는 것이다.The air conditioner operates a four-way valve so that the refrigerant flows to the indoor heat exchanger during the heating operation so that the refrigerant gas compressed by the compressor flows to the indoor heat exchanger acting as a condenser, and the heat of condensation is transferred to the indoor air. Heats the air conditioning chamber by heat exchange, expands the high-temperature / high-pressure refrigerant liquid condensed in the indoor heat exchanger in the expansion valve, and then evaporates the outdoor heat exchanger, which acts as an evaporator, as the heat source to heat the low-temperature and low-pressure gas. It is to repeat the cycle sucked into the compressor.

그리고 냉방운전시에는 4방밸브를 냉매가 실외 열교환기 측으로 흐르도록 조작하여 압축기에서 압축된 고온·고압의 냉매가스를 응축기로 작용하는 실외 열교환기에서 응축시키고, 실외 열교환기에서 응축된 고온·고압의 냉매액을 팽창밸브에서 팽창시킨 후 증발기로 작용하는 실내 열교환기에서 실내공기에 의하여 증발될 때 그 증발열에 의하여 실내공기를 냉각하여 냉방을 한 후 저온·저압의 냉매가스가 압축기에 흡입되는 사이클을 반복하는 것이다.During the cooling operation, the four-way valve is operated so that the refrigerant flows to the outdoor heat exchanger to condense the high-temperature / high-pressure refrigerant gas compressed by the compressor in the outdoor heat exchanger acting as a condenser, and the high-temperature and high pressure condensed in the outdoor heat exchanger. After the refrigerant liquid is expanded in the expansion valve and evaporated by the indoor air in the indoor heat exchanger that acts as an evaporator, the air is cooled by cooling the indoor air by the evaporation heat, and the refrigerant gas of low and low pressure is sucked into the compressor. To repeat.

한편, 히트 펌프를 이용한 공기 조화기는 난방운전시에 실외 열교환기에서 외기를 열원으로 하여 냉매액이 증발될 때 외기온도가 낮을 때에는 냉매액의 증발이 양호하지 못하여 가열능력이 현저하게 떨어지기 때문에 압축기에 흡입되는 냉매가스의 증발 촉진에 많은 노력을 하고 있다.On the other hand, the air conditioner using the heat pump is a compressor since the evaporation of the coolant liquid is not good and the heating capacity is remarkably decreased when the coolant liquid is evaporated when the coolant liquid is evaporated by the outdoor heat exchanger as a heat source during the heating operation. Efforts have been made to promote the evaporation of the refrigerant gas sucked into the gas.

그 일례로서 일본국 실용신안 출원공고 소 49­18927 호 공보에는 냉매회로 중에 2 대의 실내 열교환기를 설치하여 냉방운전시에는 그 중 1 대를 증발기로서 작용하게 하여 냉매를 증발시키고 1 대는 폐쇄하며, 난방운전시에는 2 대의 실내 열교환기를 전부 응축기로 작용하도록 하여 실내공기를 가열하는 것을 개시하고 있으며, 일본국 특허 출원공개 소 54­45949 호 공보에는 난방회로 중에 냉매가열기를 설치하여 난방운전시에 증발기로서 겸용하도록 하여 압축기에서 압축된 고온·고압의 냉매가스를 실내 열교환기에서 응축 액화하여 실내를 난방한 다음 난방용 감압기구에서 감압된 냉매액을 냉매가열기에서 증발시키므로서 외기온도가 낮을 때에도 난방능력이 저하되지 않도록 한 것이 개시되어 있으며, 또한 본 발명의 발명자는 압축기, 4방밸브, 실내 열교환기, 냉방용 감압기구, 난방용 감압기구 및 실외 열교환기를 제 1 도관과 냉매가스 흡입관으로 연결한 냉매회로에 있어서, 상기 제 1 도관의 상기 실내 열교환기와 난방용 감압기구 사이에 설치한 제 1 열교환기와, 상기 제 1 도관의 상기 실외 열교환기와 4방밸브 사이에 상기 제 1 열교환기보다 상방에 위치되게 설치되며 상기 제 1 열교환기와 밸브가 설치된 연결관으로 폐회로가 형성되게 연결한 제 2 열교환기를 구비함과 동시에 상기 제 1 및 제 2 열교환기에 작동유체를 충전하여서 상기 실내 열교환기에서 응축 액화된 냉매액을 열원으로 하여 압축기에 유입되는 냉매액 및 냉매가스의 증발을 촉진토록 한 것을 1998 특허출원 제 1344 호로 출원한 바 있다.For example, Japanese Utility Model Application Publication No. 4918927 discloses two indoor heat exchangers in a refrigerant circuit, and during cooling operation, one of them acts as an evaporator to evaporate the refrigerant and one to close the heating operation. The city discloses heating of indoor air by making both indoor heat exchangers act as condensers, and Japanese Patent Application Publication No. 5445949 discloses a refrigerant heater in a heating circuit to serve as an evaporator during heating operation. The high temperature and high pressure refrigerant gas compressed by the compressor is condensed and liquefied in an indoor heat exchanger to heat the room, and then the refrigerant pressure decompressed in the heating decompression mechanism is evaporated in the refrigerant heater, thereby reducing the heating capacity even when the outside air temperature is low. The inventors of the present invention also provide a compressor, a four-way valve, and a room. A refrigerant circuit in which a heat exchanger, a cooling pressure reducing device, a heating pressure reducing device, and an outdoor heat exchanger are connected to a first conduit and a refrigerant gas suction pipe, the first heat exchanger provided between the indoor heat exchanger and the heating pressure reducing device of the first conduit. And a second heat exchanger installed between the outdoor heat exchanger and the four-way valve of the first conduit so as to be positioned above the first heat exchanger, and connected to form a closed circuit through a connection pipe provided with the first heat exchanger and the valve. At the same time, the first and second heat exchangers are filled with a working fluid to promote the evaporation of refrigerant liquid and refrigerant gas flowing into the compressor using the refrigerant liquid condensed and liquefied in the indoor heat exchanger as a heat source. Has been filed.

그러나 상기한 일본국 실용신안 출원공고 소 49­18927 호는 난방시에 2 대의 실내 열교환기를 응축기로 작용하도록 하여 실내공기를 가열함으로서 난방능력이 저하되는 것을 방지하고 있지만 이는 압축기의 열원을 이용하여 부 열교환기에서 응축열을 추가 생성하여야 하기 때문에 압축기의 용량을 크게 하여야 함으로 설비비와 유지비가 많이 들고, 실내에 설치되는 실내 열교환기의 부피가 커지므로 실내의 점유면적을 많이 차지하여 실내공간의 활용에 제한을 받게 되며, 상기한 일본국 특허출원 공개 소 54­45945 호는 난방운전시에 냉매가열기를 증발기로 겸용하도록 되어 있지만 그 냉매가열기의 구체적인 기술수단이 기재되어 있지 않은 바, 증발기의 구조상 부피가 작고 설치가 용이한 전열을 이용할 수밖에 없으므로 유지비가 많이 들 수밖에 없는 것이다. 그리고 상기한 본 발명자의 선출원도 혹한기에는 보조가열수단을 이용하여야 하므로 구조가 복잡하고 유지비가 많이 드는 문제점이 있게되는 것이다.However, Japanese Utility Model Application Publication No. 4918927 mentioned above does not deteriorate the heating capacity by heating the indoor air by making two indoor heat exchangers act as condensers when heating, but this is caused by the heat exchange of the compressor. As the capacity of the compressor must be increased because condensation heat must be generated in the air conditioner, the equipment cost and maintenance cost are increased, and the volume of the indoor heat exchanger installed in the room becomes large, thus occupying a large occupied area of the room, thereby limiting the utilization of the indoor space. Japanese Patent Application Laid-open No. 5445945 mentioned above is designed to use a refrigerant heater as an evaporator during heating operation, but specific technical means of the refrigerant heater are not described. It is inevitable that maintenance costs are high because there is no choice but to use the heat transfer that is easy to install. will be. In addition, the above-described application of the present inventors also has a problem that the structure is complicated and the maintenance cost is high because it is necessary to use the auxiliary heating means in the cold season.

그뿐아니라 상기한 것들은 난방시에 대류난방에만 의존함으로 기류가 거주자에 직접 닿게 되어 쾌적한 난방을 할 수 없는 것이다. 그리고 본 발명자의 선출원은 난방과 동시에 온수를 생성하기 위하여 온수가열조를 실내 열교환기를 바이패스시켜 설치하였으나, 온수는 난방시에만 생성할 수 있고 냉방시에는 불가능하며, 온수의 가열효율도 낮은 문제점이 있는 것이다.In addition, the above-mentioned things rely only on convection heating for heating, so that the airflow directly touches the occupants and thus cannot provide comfortable heating. And the prior application of the present inventors installed the hot water heating tank bypass the indoor heat exchanger in order to generate hot water at the same time heating, but hot water can be generated only when heating and cooling is not possible, the heating efficiency of the hot water is also low It is.

본 발명은 상기한 문제점을 감안하여 구조가 간단하며 별도의 열원을 사용하지 않고 외기온이 낮을 때에도 난방(건조포함)능력을 양호하게 유지할 수 있고, 난방시에 대류난방 및 복사난방을 겸용하므로서 쾌적한 난방을 할 수 있도록 한 공기 조화기를 제공하는 것을 목적으로 한다.The present invention has a simple structure in view of the above problems and can maintain a good heating (including drying) ability even when the outside air temperature is low without using a separate heat source, comfortable heating by combining convection heating and radiant heating during heating The purpose is to provide an air conditioner to enable this.

본 발명의 다른 목적은 난방 또는 냉방(냉장포함)운전시에 항상 온수도 생성할 수 있는 공기 조화기를 제공하는 것이다.Another object of the present invention is to provide an air conditioner capable of always producing hot water during heating or cooling (including refrigeration) operation.

다음 작동을 기능별로 설명한다.The following operations are explained by function.

1. 냉난방 및 온수 가열운전1. Heating and Heating

본 발명에 있어서 난방(건조포함) 또는 냉방(냉장포함)운전시에는 밸브(15)만을 개방한 후 난방운전시에는 4방밸브(3)를 냉매가 화살표 실선으로 흐르도록 조작하고, 냉방운전시에는 4방밸브(3)를 냉매가 화살표 점선으로 흐르도록 조작하여 난방시에는 실내 열교환기(4)를 응축기로 작용하도록 하여 그 응축열에 의하여 공기 조화실을 대류난방하고, 냉방시에는 실내 열교환기(4)를 증발기로 작용하도록 하여 그 증발열에 의하여 공기 조화실을 냉방하는 것은 종래의 것과 동일한 것이다.In the present invention, during the heating (including drying) or cooling (including refrigeration) operation, only the valve 15 is opened, and during the heating operation, the four-way valve 3 is operated so that the refrigerant flows in the solid arrow line, and during the cooling operation. The four-way valve (3) is operated so that the refrigerant flows through the dotted line of the arrow. When heating, the indoor heat exchanger (4) acts as a condenser, and convection heating of the air conditioning chamber by the heat of condensation. It is the same as the conventional thing to make (4) act as an evaporator, and to cool an air conditioning chamber by the heat of evaporation.

상기와 같이 난방운전을 할 때 밸브(16)를 개방하면 압축기(1)에서 압축된 고온·고압의 냉매가스는 바이패스관(101)을 흐르면서 열교환기(102)와 열교환관계에 있는 온수 열교환기(103)를 흐르는 급수를 가열하고 가열된 온수는 순환펌프 (106)에 의하여 복사열 발생수단(104)을 순환하면서 복사열을 방출하여 실내를 복사난방하게 되는 것이므로 즉 실내를 난방할 때 통상의 대류난방을 함과 동시에 복사난방을 함으로서 실내의 온도차가 없게 되는 것이다.When the valve 16 is opened during the heating operation as described above, the hot and high pressure refrigerant gas compressed by the compressor 1 flows through the bypass pipe 101, and the hot water heat exchanger having a heat exchange relationship with the heat exchanger 102. Heated water flowing through the 103 and heated hot water circulates the radiant heat generating means 104 by the circulation pump 106 to radiate radiant heat to radiantly heat the room, that is, normal convection heating when heating the room. At the same time radiant heating is performed so that there is no temperature difference in the room.

상기와 같이 실내를 대류난방 및 복사난방을 겸할 때 밸브(16)의 개방도를크게 하여 바이패스관(101)을 흐르는 냉매가스량을 중대함으로서 복사열 발생수단 (104)에서의 복사열을 증대하고, 실내 열교환기(4)를 흐르는 냉매가스량을 감소하여 실내 열교환기(4)에서의 방열량을 감소함과 동시에 팬(미도시)의 회전수를 감소시키면 소음이 감소되고 기류가 거주자의 피부에 닿게 되는 양이 적게 되어 쾌적한 난방을 할 수 있는 것이다. 그뿐아니라 상기와 같이 난방운전을 할 때 밸브(19)를 개방하고 온수 순환관 (105)에 급수를 하여 온수 열교환기(103)에서 가열된 온수를 온수 공급관 (108)을 통하여 목욕용 및 급탕용에 사용할 수 있는 것이다.As described above, when the room serves both convection heating and radiant heating, the opening degree of the valve 16 is increased to increase the amount of refrigerant gas flowing through the bypass pipe 101, thereby increasing radiant heat in the radiant heat generating means 104, and By reducing the amount of refrigerant gas flowing through the heat exchanger (4) to reduce the amount of heat dissipation in the indoor heat exchanger (4) and at the same time reducing the number of revolutions of the fan (not shown), the amount of noise is reduced and the airflow reaches the skin of the occupant There is little and can do comfortable heating. In addition, when the heating operation is performed as described above, the valve 19 is opened and the hot water circulation pipe 105 is supplied to supply hot water heated in the hot water heat exchanger 103 for bathing and hot water supply through the hot water supply pipe 108. It can be used.

그리고 상기와 같이 냉방운전을 할 때 난방운전시와 동일하게 급수가 가열되므로서 냉방과 동시에 온수를 사용할 수 있으며, 이때 열교환기(102)는 실외 열교환기(7)와 함께 응축기의 기능을 함으로서 냉매가스의 응축이 양호하기 때문에 냉방효율을 증대할 수 있게 된다.When the cooling operation is performed as described above, the water is heated in the same manner as in the heating operation, and thus the hot water can be used simultaneously with the cooling. At this time, the heat exchanger 102 functions as a condenser together with the outdoor heat exchanger 7 to form a refrigerant. Since the condensation of the gas is good, the cooling efficiency can be increased.

또한 바이패스관(101)은 도관(8a)의 압축기(2)와 4방밸브(3) 사이에 연결함으로서 압축기(2)에서 토출되는 고온·고압의 냉매가스에 의하여 온수를 가열할 수 있기 때문에 온수 가열효율이 양호하고, 종래 4방밸브 후방에 온수가열조를 설치한 것에 비하여 배관을 단순화 할 수 있는 것이다.In addition, since the bypass pipe 101 is connected between the compressor 2 of the conduit 8a and the four-way valve 3, hot water can be heated by the high-temperature / high-pressure refrigerant gas discharged from the compressor 2. The hot water heating efficiency is good, and the piping can be simplified as compared to the conventional hot water heating tank installed behind the four-way valve.

2. 증발촉진운전2. Evaporation promotion operation

상기 1과 같은 난방운전시에 외기온이 하강하면 응축기로 작용하는 실내 열교환기(4)에서 냉각된 비교적 고온·고압의 냉매액이 도관(8c)에 설치한 가열 열교환기(12)를 경유할 때 축열조(11)에 내장된 축열재에 응축열을 방출함으로서 그 응축열을 축열재에 축열 저장함과 동시에 가열 열교환기(12)에서의 방열에 의하여 실외 열교환기(7)에 유입되는 냉매액의 온도 및 압력을 낮추므로서 냉매액의 실외 열교환기(7)에서의 증발을 양호하게 할 수 있고, 한편 증발기로 작용하는 실외 열교환기(7)에서 외기를 열원으로 하여 냉매액이 증발될 때 증발이 양호하지 못한 습포화 냉매가스는 4방밸브(3)를 통하여 흡기 도관(9)에 설치한 흡열 열교환기(13)를 경유하여 압축기(2)에 흡입되면서 축열조(11)에 내장한 축열재에 축열된 열에 의하여 가열되어 재증발한 후 압축기(2)에 흡입됨으로서 압축기(2)에 흡입되는 냉매가스는 건포화 또는 과열 냉매가스 상태로 흡입되는 것이다.When the outside air temperature drops during the heating operation as described above, when the relatively high temperature and high pressure refrigerant liquid cooled by the indoor heat exchanger 4 acting as a condenser passes through the heating heat exchanger 12 installed in the conduit 8c. The temperature and pressure of the refrigerant liquid flowing into the outdoor heat exchanger 7 by dissipating the condensation heat in the heat storage material built into the heat storage tank 11 and storing the heat of condensation heat in the heat storage material and heat radiation from the heat exchanger 12. It is possible to improve evaporation of the refrigerant liquid in the outdoor heat exchanger 7 by lowering the temperature, while evaporation is not good when the refrigerant liquid is evaporated using the outdoor air as a heat source in the outdoor heat exchanger 7 serving as the evaporator. Unsaturated wet refrigerant gas is sucked into the compressor (2) via the endothermic heat exchanger (13) installed in the intake conduit (9) through the four-way valve (3) is stored in the heat storage material built in the heat storage tank (11) Heated by heat to re-evaporate, then compressed The refrigerant gas sucked into the compressor 2 by being sucked into the machine 2 is sucked in a state of dry saturation or superheated refrigerant gas.

그리고 상기한 증발촉진운전시에 가열 열교환기(12)의 응축열만으로서 압축기(2)에 흡입되는 냉매가스가 건포화 또는 과열되지 않거나 외기온이 더욱더 하강하였을 경우에는 온수 바이패스관(109)에 설치한 밸브(17)를 개방하고 온수 순환관 (105)에 설치한 밸브(18)를 폐쇄한 후 온수 가열회로(10)를 작동시키면 온수 열교환기(103)에서 생성된 온수는 온수 바이패스관(109)를 흐르면서 제 2 가열 열교환기(14)에서 축열재와 열교환하여 축열재에 추가 축열됨으로서 축열량이 대폭 증대되기 때문에 흡입도관(9)을 흐르는 습포화 냉매가스는 건포화 또는 과열 냉매가스가 되어 압축기(2)에 흡입됨으로서 외기온이 더욱 더 낮을 때에도 가열능력을 양호하게 유지할 수 있고 압축기(2)의 습압축이 방지되어 신뢰성을 확보할 수 있는 것이다.When the refrigerant gas sucked into the compressor 2 by the heat of the heat exchanger 12 is not condensed or overheated or the outside air temperature is further lowered during the evaporation promotion operation, the hot water bypass pipe 109 is installed. When one valve 17 is opened and the valve 18 installed in the hot water circulation pipe 105 is closed and the hot water heating circuit 10 is operated, the hot water generated by the hot water heat exchanger 103 is a hot water bypass pipe ( Since the heat storage amount is greatly increased by heat-exchanging with the heat storage material in the second heat exchanger 14 while additionally accumulating the heat storage material as 109 flows through, the wetted refrigerant gas flowing through the suction conduit 9 is dried or superheated refrigerant gas. By being sucked into the compressor 2, even when the outside air temperature is lower, the heating capacity can be maintained satisfactorily, and the wet compression of the compressor 2 can be prevented to ensure the reliability.

이상과 같이 본 발명은 기본 냉매회로에 온수 가열회로를 설치하여 대류난방과 복사난방을 동시에 실시할 수 있음으로 소음이 감소되고 기류가 거주자에게 닿는 양을 작게 할 수 있어서 쾌적한 난방을 할 수 있으며, 또한 가열 열교환기 및 흡열 열교환기를 내장한 축열조를 설치하여 압축기에 흡입되는 습포화 냉매가스를 건포화 또는 과열화할 수 있기 때문에 외기온이 낮을 때에도 간단한 구조와 별도의 열원을 사용하지 않고 가열능력을 양호하게 유지할 수 있고, 압축기의 습압축이 방지되어 신뢰성을 확보할 수 있는 것이다.As described above, the present invention can provide convective heating and radiant heating at the same time by installing a hot water heating circuit in the basic refrigerant circuit so that the noise can be reduced and the amount of airflow reaching the occupants can be reduced. In addition, by installing a heat storage tank with a built-in heating heat exchanger and an endothermic heat exchanger, it is possible to dry or overheat the wetted refrigerant gas sucked into the compressor, so that even when the outside air temperature is low, a simple structure and a good heat capacity are not used without a separate heat source. It is possible to maintain and prevent the wet compression of the compressor to ensure the reliability.

또한 냉·난방시에 항상 온수를 생성하여 사용할 수 있으므로 편의성이 증진되는 것이다.In addition, since the hot water can always be generated and used during cooling and heating, convenience is increased.
