Description
본 발명은 1대의 실외기 유닛에 복수대의 실내기 유닛이 함께 접속되어 사용되는 멀티 에어콘(multi-air conditioner)에 관한 것으로, 보다 상세하게는 단일의 공유 압축기를 최대한 활용하여 에어콘의 효율을 향상시킨 멀티 에어콘에 관한 것이다.The present invention relates to a multi-air conditioner in which a plurality of indoor unit units are connected to one outdoor unit and used together. More particularly, the present invention relates to a multi-air conditioner that utilizes a single shared compressor to maximize the efficiency of the air conditioner. It is about.
일반적으로, 에어콘과 같은 공기조화장치(A AIR CONDITIONER APPLIANCE)는 냉매가 액체에서 기체로 기화(증발)할 때 냉장고 내주의 열을 흡수함으로써 내부의 공기가 차가와지는 원리를 이용한다.Generally, A AIR CONDITIONER APPLIANCE, such as an air conditioner, utilizes the principle that the inside air becomes cold by absorbing heat of the interior of the refrigerator when the refrigerant evaporates (evaporates) from the liquid to the gas.
통상 에어콘은 하나의 몸체로 구성되는 창문형과, 1대의 실외기 유닛 및 복수개의 실내기 유닛으로 각각 구성된 분리형으로 크게 대별된다.Usually, the air conditioner is roughly divided into a window type composed of one body, and a separate type composed of one outdoor unit and a plurality of indoor unit.
그 중 분리형 에어콘에서 복수개의 실내기 유닛은 건물 내부에 설치하고, 1개의 실외기 유닛은 별도로 건물 외부로 설치한다. 이처럼, 실내기 유닛과 실외기 유닛을 분리하여 설치할 수 있기 때문에 건물 내부와 외부가 통하는 별도의 창문을 만들 필요가 없다.Among the separate air conditioners, a plurality of indoor unit is installed inside the building, and one outdoor unit is separately installed outside the building. As such, since the indoor unit and the outdoor unit can be installed separately, there is no need to make a separate window between the inside and the outside of the building.
또한, 이러한 분리형 에어콘은 실외기 유닛을 건물 외부에 별도로 설치함으로써 소음을 줄일 수 있으며, 복수개의 실내기 유닛도 벽결이 형태로 설치가능하므로 실내공간의 점유 면적을 줄일 수 있는 장점이 있으므로 현재 널리 보급되고 있는 추세다.In addition, the separate air conditioner can reduce noise by separately installing the outdoor unit in the outside of the building, and since a plurality of indoor unit units can be installed in the form of wall texture, there is an advantage of reducing the occupied area of the indoor space. It's a trend.
이와 같은 분리형 에어콘은 실내기 유닛과 실외기 유닛이 분리 설치가능하므로 실내기 유닛 1대에 복수개의 실내기 유닛을 함께 연결하여 사용가능한 멀티 에어콘으로서의 구성이 가능해진다.Since the detachable air conditioner can be installed separately from the indoor unit and the outdoor unit, it is possible to configure a multi-air conditioner that can be used by connecting a plurality of indoor unit to one indoor unit.
즉, 가정용 룸 에어콘의 보급율이 늘어남에 따라 1채의 집에 2대 이상의 에어콘을 설치하거나, 사무소, 빌딩, 점포, 병원 등 사무실이 다수의 장소마다 각각의 에어콘을 설치할 경우 건물 내부의 각 사무실에 복수개의 실내기 유닛을 설치하고 건물 외부에 하나의 실외기 유닛을 설치한 후, 이 실외기 유닛과 건물 내부에 있는 복수개의 실내기 유닛을 연결하여 사용하는 구조로 이루어진다.In other words, as the spread of household room air conditioners increases, when two or more air conditioners are installed in one house, or when offices such as offices, buildings, stores, and hospitals install their own air conditioners in multiple places, After installing a plurality of indoor unit and installing one outdoor unit outside the building, the outdoor unit and the plurality of indoor unit inside the building are connected and used.
이와 같이 구성된 통상적인 멀티 에어콘은, 제1도에 도시하는 바와 같이, 실내기 유닛(1)와 실내기 유닛(2)로 구성된다.The conventional multi-air conditioner configured as described above is constituted by the indoor unit 1 and the indoor unit 2, as shown in FIG.
그리고, 실내기 유닛(1)은 벽걸이형 또는 스텐다드형으로 실내에 설치되며, 실외기 유닛(2)은 건물 외부에 설치된다. 실외기 유닛(2)은 복수개의 압축기(3)가 구비되어, 증발기(도시하지 않음)로부터 기체 냉매를 흡입하여 저온 저압상태의 냉매(REFRIGERANT)를 압축하여 고온 고압상태의 냉매가스로 압축 분사한다.The indoor unit 1 is installed indoors in a wall-mounted or standard type, and the outdoor unit 2 is installed outside the building. The outdoor unit 2 is provided with a plurality of compressors 3, sucks gaseous refrigerant from an evaporator (not shown), compresses the refrigerant REFRIGERANT at low temperature and low pressure, and compresses and sprays the refrigerant gas at a high temperature and high pressure.
이때, 사용되는 냉매로는 저온의 열원으로부터 고온의 열원에 열을 운반하는 동작유체로서, 통상적으로 프레온(R-12)가 사용된다.In this case, as the refrigerant used, a freon (R-12) is generally used as an operating fluid for transferring heat from a low temperature heat source to a high temperature heat source.
한편, 고온 고압의 기체 냉매는 응축기(5)로 유입된다. 이 응축기(5)는 주위의 온도와 열교환하여 기체에서 고온 고압상태의 액체로 변환 응축하여 열을 외부로 전도 발산한다.On the other hand, the high temperature and high pressure gas refrigerant flows into the condenser 5. The condenser 5 exchanges heat with ambient temperature, converts it from a gas into a liquid at a high temperature and high pressure, and conducts and dissipates heat to the outside.
그리고 고온 고압상태의 냉매는 일정압역 이상이 되면 교축 통과시키는 팽창밸브(6 : EXPASION VALVE)를 통과하여 실내기 유닛(1)으로 흐르게 된다. 미설명 부호(7)는 송풍팬을 지시하는 것이다. 화살표 흐름 방향은 냉매 순환을 지시하는 것이다.When the refrigerant at a high temperature and high pressure is above a predetermined pressure range, the refrigerant flows through the expansion valve (expansion valve 6) passing through the throttle to the indoor unit 1. Reference numeral 7 denotes a blowing fan. The arrow flow direction indicates the refrigerant circulation.
그러나 전술한 바와 같이 구성된 종래 멀티 에어콘은 복수개의 실내기 유닛에 대응하는 복수개의 압축기가 실외기 유닛에 연결되어 과다한 냉방 부하가 동시에 걸리므로 냉방 효율이 떨어지는 문제점이 존재하였다.However, in the conventional multi-air conditioner configured as described above, a plurality of compressors corresponding to the plurality of indoor unit units are connected to the outdoor unit so that excessive cooling loads are simultaneously applied, thereby reducing the cooling efficiency.
또한, 복수개의 압축기의 능력을 가변적으로 변화시켜가며 적절한 조절용 절환밸브 조작에 의해 냉매유량을 분배하므로 제어조작이 복잡하고 다수의 실내기 중 일부가 능력이 변하면 나머지 실내기의 능력이 변하면 나머지 실내기의 능력변화가 없어도 해당 변화량 만큰의 능력변화가 다른 실내기에 전가되어 제어불능 상태에 이르는 단점이 있었다.In addition, since the capacity of the plurality of compressors is variably changed and the refrigerant flow rate is distributed by an appropriate regulating switching valve operation, the control operation is complicated. Even if there is no, the change of the capacity of 10,000 million was transferred to another indoor unit, which resulted in an uncontrollable state.
본 발명은 종래의 문제점을 해결하기 위한 거스로, 복수개의 실내기 유닛에 각각 1개씩의 냉매유로를 할당할 수 있도록 응축기의 냉매 순환 구역을 분할하여 냉매회로를 구성함으로써 단일의 공유 압축기로도 각각의 실내기 유닛의 독립적인 제어가 용이할 뿐만 아니라 시스템의 단순화에 따른 제품의 수율 및 원가절감을 도모한 멀티 에어콘을 제공하는데 있다.The present invention is a gus to solve the conventional problems, by dividing the refrigerant circulation zone of the condenser to configure a refrigerant circuit so as to allocate one refrigerant passage to each of the plurality of indoor unit units each by a single shared compressor Not only is it easy to control the indoor unit independently, but also to provide a multi-air conditioner to reduce the yield and cost of the product according to the system simplification.
상기와 같은 목적을 달성하기 위한 본 발명은 멀티 에어콘에 있어서, 복수의 증발기와, 각 증발기에 선택적으로 냉매 흐름을 절환할 수 있는 제1냉매 절환밸브가 마련된 실내기 유닛과; 단일의 압축기와, 상기 각 증발기에 대응하도록 증발기와 동일한 개수의 분할된 영역으로 이루어진 응축기와, 상기 압축기에서 상기 응축기의 분할된 영역으로 냉매 흐름을 선택적으로 절환할 수 있는 제2냉매 절환밸브와, 송풍팬이 마련된 실외기 유닛과; 상기 실외기 유닛에서 상기 실내기 유닛으로 흐르는 냉매의 압력을 팽창시키기 위해 상기 응축기의 분할된 영역에 대응하도록 상기 분할된 영역과 동일한 개수로 마련된 팽창밸브와; 상기 각 증발기의 입구측 또는 출구측에서 냉매의 온도를 개별적으로 검출하기 위한 온도감지수단과; 상기 각각의 증발기에서 압축기로 흐르는 냉매의 압력을 균일하게 하기 위한 균압수단을 포합한다.According to an aspect of the present invention, there is provided a multi-air conditioner including: a plurality of evaporators and an indoor unit provided with a first refrigerant switching valve capable of selectively switching a refrigerant flow in each evaporator; A condenser composed of a single compressor, an equal number of divided regions corresponding to each of the evaporators, a second refrigerant switching valve capable of selectively switching the refrigerant flow from the compressor to the divided regions of the condenser, An outdoor unit provided with a blowing fan; Expansion valves provided in the same number as the divided regions so as to correspond to the divided regions of the condenser to expand the pressure of the refrigerant flowing from the outdoor unit to the indoor unit; Temperature sensing means for individually detecting the temperature of the refrigerant at the inlet or outlet of each evaporator; And equalizing means for equalizing the pressure of the refrigerant flowing from the respective evaporators to the compressor.

이하, 본 발명에 따른 멀티 에어콘에 대한 하나의 바람직한 실시예를 첨부된 도면에 의거하여 상세하게 설명한다.Hereinafter, one preferred embodiment of a multi air conditioner according to the present invention will be described in detail with reference to the accompanying drawings.
제2도는 본 발명 멀티 에어콘을 설명하기 위하여 도시한 도면이다.2 is a view for explaining the multi-air conditioner of the present invention.
제2도에 도시된 멀티 에어콘에서 실내기 유닛(10)은 복수의 증발기(14)와, 각 증발기(14)에 선택적으로 냉매 흐름을 절환할 수 있는 제1냉매 절환밸브(12)가 마련된다.In the multi-air conditioner shown in FIG. 2, the indoor unit 10 is provided with a plurality of evaporators 14 and a first refrigerant switching valve 12 capable of selectively switching the refrigerant flow in each of the evaporators 14.
실외기 유닛(20)은 단일의 압축기(21)와, 상기 각 증발기(14)에 대응하도록 증발기(14)와 동일한 개수의 분할된 영역으로 이루어진 응축기(23)와, 상기 압축기(21)에서 상기 응축기(23)의 분할된 영역으로 냉매 흐름을 선택적으로 절환할 수 있는 제2냉매 절환밸브(22)와, 송풍팬(24)이 마련된다.The outdoor unit 20 includes a single compressor 21, a condenser 23 having the same number of divided regions as the evaporator 14 so as to correspond to each of the evaporators 14, and the condenser in the compressor 21. A second refrigerant switching valve 22 and a blowing fan 24 capable of selectively switching the refrigerant flow to the divided region of 23 are provided.
팽창밸브(24)는 실외기 유닛(20)에서 상기 실내기 유닛(10)으로 흐르는 냉매의 압력을 팽창시키기 위해 상기 응축기(23)의 분할된 영역과 대응하는 각각의 증발기(14) 사이마다 동일한 개수로 마련된다.The expansion valve 24 is equally numbered between the divided region of the condenser 23 and each corresponding evaporator 14 to expand the pressure of the refrigerant flowing from the outdoor unit 20 to the indoor unit 10. Prepared.
온도감지수단(11)은 상기 각 증발기(14)의 입구측 또는 출구측에서 냉매의 온도를 개별적으로 검출할 수 있도록 설치된다. 예시도면에서는 온도감지수단(11)이 출구측에 설치된 것이다.The temperature sensing means 11 is provided to individually detect the temperature of the refrigerant at the inlet side or the outlet side of each of the evaporators 14. In the exemplary drawing, the temperature sensing means 11 is installed at the outlet side.
균압수단(30)은 각각의 증발기(14)를 통과한 냉매의 압력을 균일하게 하여 압축기(21)로 공급할 수 있도록 균압수단(30)의 입구측은 각각의 증발기(14)의 출구측 복수개의 냉매관로가 연결되고 출구측은 압축기(21)의 입구측 단일의 냉매관로와 연결된다.The inlet side of the equalizing means 30 has a plurality of outlet side of each evaporator 14 so that the equalizing means 30 can uniformly supply the pressure of the refrigerant passing through each evaporator 14 to the compressor 21. Two refrigerant lines are connected and the outlet side is connected with a single refrigerant line at the inlet side of the compressor 21.
그리고, 균압수단(30)은 본 출원인에 의해 동일자로 출원하는 멀티 에어콘에 자세히 개시되어 있다.And, the equalizing means 30 is disclosed in detail in the multi air conditioner filed by the applicant as the same.
상기와 같이 구성된 본 발명 멀티 에어콘의 작용 효과를 설명하면 다음과 같다. 먼저, 온도 감지 수단(11)은 실내기 유닛(10)온도를 감지하여 미리 결정된 소정의 설정 온도와 비교 판단하여 제 냉매 절환 밸브(12)를 제어하여 냉매 유량을 제어한다.Referring to the effect of the present invention the multi-air conditioner configured as described above are as follows. First, the temperature detecting means 11 detects the temperature of the indoor unit 10 and compares it with a predetermined predetermined temperature to control the refrigerant switching valve 12 to control the refrigerant flow rate.
이에 따라 조절된 냉매 유량은 균압수단(30)으로 순환한다. 균압수단(30)에서는 각각의 증발기(14)에서 나온 냉매의 압력을 균등하게 하여 압축기(21)로 흐르도록 한다.The refrigerant flow rate thus adjusted circulates to the equalization means 30. In the equalization means 30, the pressure of the refrigerant from each evaporator 14 is equalized to flow to the compressor 21.
압축기(21)에서는 증발기(14)를 거쳐 나온 저온 저압 상태의 기체 냉매를 흡입하여 고온 고압상태의 냉매가스로 압축하여 응축기(23)로 보낸다.The compressor 21 sucks the gaseous refrigerant in the low temperature and low pressure state passed through the evaporator 14, compresses the gaseous refrigerant in the high temperature and high pressure state, and sends it to the condenser 23.
한편, 제2냉매 절환밸브(22)는 온도 감지 수단(11)의 제어에 의해 선택적으로 개폐된 제1냉매 절환 밸브(12)의 상태와 동일하게 선택적으로 개폐되어 증발기(14)의 냉방능력에 대응하는 만큼의 응축기(23)의 분할 영역에서만 응축이 이루어진다.On the other hand, the second refrigerant switching valve 22 is selectively opened and closed in the same manner as the state of the first refrigerant switching valve 12 that is selectively opened and closed by the control of the temperature sensing means 11 to the cooling capacity of the evaporator 14. Condensation takes place only in the corresponding divided regions of the condenser 23.
한편, 압축기(21)에서는 선택된 증발기(14)의 냉방능력에 따라 가변적으로 압축능력을 변화시켜 냉매의 압력을 적절하게 유지한다.On the other hand, in the compressor 21, the compression capacity is variably changed according to the cooling capacity of the selected evaporator 14 to maintain the pressure of the refrigerant appropriately.
이처럼 본 발명에 따르면 분할된 영역을 갖는 단일의 응축기와 단일의 압축기만으로 복수개의 증발기를 냉방부하 용량변화에 온도감지수단(11) 및 제1, 2냉매 절환 밸브(12, 22)를 통해 단순한 방법으로 대응할 수 있다.특히, 응축기(23)의 영역을 분할하여 냉매의 순환 영역을 선택적으로 지정할 수 있어 어느 일측 실내기 유닛의 부하변동에 대한 영향이 다른 실내기 유닛에 전가되는 문제가 발생되지 않으며, 냉방운전의 안정성을 높일 수 있다.As described above, according to the present invention, a single condenser having a divided area and a single compressor alone provide a simple method through the temperature sensing means 11 and the first and second refrigerant switching valves 12 and 22 to change the cooling load capacity. In particular, the area of the condenser 23 can be divided to selectively designate the circulation region of the refrigerant, so that the effect of the load fluctuation of one indoor unit unit is not transferred to another indoor unit. The stability of the operation can be improved.
또한, 단일의 압축기(21)만으로 이루어지므로 장치의 단순화를 가져올 수 있다.In addition, since it consists of a single compressor 21 only, the apparatus can be simplified.
한편, 상기한 실시예는 본 발명의 바람직한 하나의 실시예를 설명한 것에 불과하고, 본 발명의 적용범위는 이와 같은 것에 한정되는 것은 아니며, 동일사상의 범주내에서 적절하게 변경, 변화 및 변형가능한 것이다.On the other hand, the above embodiment is only to describe one preferred embodiment of the present invention, the scope of the present invention is not limited to such, and can be appropriately changed, changed and modified within the scope of the same idea. .
이상에서와 가이 본 발명에 따른 멀티 에어콘에 의하면, 개별 냉방부하 변화에 따른 시스템 제어가 단순하며, 압축기의 압력 불균형에 의해 부하를 해결하는 동시에, 냉방 용량 변화에 따른 설계 변경시 압축기를 단위 세트로 추가시킴으로써 제품의 수율 및 원가절감을 도모하는 효과가 있다.As described above, according to the multi-air conditioner according to the present invention, the system control according to the individual cooling load change is simple, solves the load by the pressure imbalance of the compressor, and at the same time, the compressor as a unit set when changing the design according to the cooling capacity change By adding it, the yield and cost of a product can be reduced.
또한, 본 발명은 온도감지수단에 의해서 유량조작을 위한 밸브 조작이 독립저긍로 수행되므로 각 실내의 냉방 부하 변동에 따라 전체적인 시스템의 제어도 용이한 효과가 있다.In addition, since the valve operation for the flow rate operation is independently performed by the temperature sensing means, the present invention also has an easy effect of controlling the entire system according to the cooling load variation of each room.
