본 발명은 유니터리 공기조화기에 관한 것으로, 특히 2-스테이지 써모스태트를 그대로 사용하면서도, 서로 다른 용량을 가진 두개의 압축기를, 3-스테이지로 운전시킴으로써, 부하 대응 능력을 향상시키도록 한 유니터리 공기조화기의 운전제어방법에 관한 것이다.The present invention relates to a unitary air conditioner, and in particular, a unitary air that improves load handling capability by operating two compressors having different capacities in three stages while still using a two-stage thermostat. It relates to a control method of operation of the harmonic.

일반적으로 유니터리 공기조화기(Unitary Air condition System)는 공장, 사무실, 호텔, 가정 등의 지하실에 구비하는 냉난방 기구를 이용하여 한 곳에서 냉풍 또는 온풍을 만들고, 이를 건물내 벽체 등에 구비한 덕트(duct)를 통해 개별 공간으로 이송하여 공급하는 중앙집중식 냉난방 시스템의 일종이다.In general, a unitary air conditioner (Unitary Air Condition System) is used to create a cold or hot air in one place by using the heating and cooling equipment in the basement of the factory, office, hotel, home, etc. It is a kind of central heating and cooling system that transfers and supplies to individual space through duct.

유니터리 공기조화기는 냉난방이 필요한 영역과 필요하지 않은 영역을 구분하여 개별 영역마다 냉풍 또는 온풍을 독립적으로 공급할 수 있도록 대개 덕트의 중간에 영역제어기(zone controller)를 설치하거나, 또는 영역의 개수에 따라 복수 개의 냉난방 기구를 독립적으로 설치하고 있다.Unitary air conditioners usually have a zone controller in the middle of the duct so that they can independently supply cold or warm air to each area by separating the areas that need air conditioning and heating. Plural air-conditioning appliances are installed independently.

도 1 및 도 2는 히트펌프형 냉동사이클을 이용한 종래 유니터리 공기조화장치의 일례를 보인 모식도 및 계통도이다.1 and 2 is a schematic diagram and a system diagram showing an example of a conventional unitary air conditioner using a heat pump type refrigeration cycle.

이에 도시한 바와 같이 종래 유니터리 공기조화장치는, 건물(도면에선 2층 주택)의 외부에 고정 설치하는 한 개의 실외기(1)와, 실외기(1)의 제1 교환기(1b)와 냉매관으로 연결하여 상기한 건물의 지하실이나 별채 등에 고정 설치하는 냉온풍기(2)와, 냉온풍기(2)의 급기구와 배기구에 각각 연결하여 상기한 건물의 각 층 벽채에 분리 매설하는 급기덕트(3) 및 배기덕트(4)와, 급기덕트(3)와 배기덕트(4)의 중간에 설치하여 각 층으로의 급기 및 배기를 구분하는 영역조절기(5a~5d)를 포함하고 있다.As shown in the drawing, a conventional unitary air conditioner includes one outdoor unit 1 fixed to an exterior of a building (two-story house in the drawing), a first exchanger 1b of the outdoor unit 1, and a refrigerant pipe. Connected to the cold and hot air fan (2) to be fixed to the basement or detached building of the building, and the air supply duct (3) to separate and buried in each floor wall of the building by connecting to the air supply and exhaust ports of the cold and hot air fan (2), respectively. And area regulators 5a to 5d disposed between the exhaust duct 4 and the air supply duct 3 and the exhaust duct 4 to distinguish the air supply and exhaust to each layer.

실외기(1)는 케이스의 내부에 설치하여 냉매가스를 압축하는 한 개 이상의 압축기(1a)와, 압축기(1a)에 냉매관으로 연결하여 냉매가스를 응축(냉방운전시)하거나 잠열을 흡수(난방운전시)하는 제1 열교환기(1b)와, 냉매가스의 압력을 감압팽 창하는 팽창기구(1c)와, 외부의 공기를 제1 열교환기(1b)로 공급하여 그 열교환기 (1b)의 열교환성능을 높이는 실외팬(미도시)으로 이루어져 있다.The outdoor unit 1 is installed inside the case of at least one compressor (1a) for compressing the refrigerant gas, and connected to the compressor (1a) by a refrigerant pipe to condensate the refrigerant gas (at cooling operation) or absorb latent heat (heating) The first heat exchanger 1b for operation), the expansion mechanism 1c for decompressively expanding the pressure of the refrigerant gas, and external air to the first heat exchanger 1b to supply the external heat exchanger 1b. It consists of an outdoor fan (not shown) to increase the heat exchange performance.

냉온풍기(2)는 케이스의 내부에 상기한 제1 열교환기(1b)에 일단을 연결하는 동시에 팽창기구(1c)에 타단을 연결하는 제2 열교환기(2a)와, 제2 열교환기(2a)의 하류에 위치하여 냉풍 또는 온풍을 상기한 급기덕트(3)로 유도하는 급기팬(미도시)으로 이루어져 있다. 냉온풍기의 케이스는 그 내부에 상기한 제2 열교환기(2a)와 급기팬(미도시)을 수용하도록 대체로 "유(U)"자 모양의 공기유로를 형성하고, 그 공기유로의 급기측에는 급기덕트(3)를, 배기측에는 배기덕트(4)를 각각 연결하고 있다.The cold / hot air blower 2 has a second heat exchanger 2a which connects one end to the first heat exchanger 1b described above and connects the other end to the expansion mechanism 1c inside the case, and a second heat exchanger 2a. Located in the downstream of the) consists of an air supply fan (not shown) for inducing cold or warm air to the air supply duct (3). The case of the cold and hot air fan has a generally "U" shaped air flow path for accommodating the second heat exchanger 2a and an air supply fan (not shown) therein, and the air supply air supply side is provided on the air supply side of the air flow path. The duct 3 is connected to the exhaust duct 4 on the exhaust side, respectively.

급기덕트(3)와 배기덕트(4)는 전술한 바와 같이 냉온풍기(2)의 급기구와 배기구에 연결하여 해당 영역(Z1,Z2)에 분관 매설하고, 각 급기덕트(3)와 배기덕트 (4)에는 해당 영역에 냉풍이나 온풍을 공급하는 토출구(3a)와 실내공기를 순환하도록 흡입하는 흡입구(4a)를 형성하고 있다.The air supply duct 3 and the exhaust duct 4 are connected to the air supply port and the exhaust port of the cold / hot air fan 2 as described above, and are embedded in the corresponding areas Z1 and Z2, and the respective air supply ducts 3 and the exhaust ducts are installed. In (4), a discharge port 3a for supplying cold or warm air and a suction port 4a for suctioning the indoor air are formed in the area.

영역조절기(5a~5d)는 통상 냉풍이나 온풍을 해당 영역으로 구분하여 공급할 수 있도록 그 해당 영역(Z1,Z2)에 매설된 급기덕트(3)의 중간과 배기덕트(4)의 중간에 설치하는 일종의 밸브로서, 해당 영역의 온도나 습도 등을 검출하여 이 검출된 값과 설정값을 비교하여 자동으로 온/오프 할 수 있도록 제어부(미도시)에 연결하거나 또는 수동으로 조작하도록 이루어져 있다.The zone regulators 5a to 5d are usually installed in the middle of the air supply duct 3 embedded in the corresponding zones Z1 and Z2 and in the middle of the exhaust duct 4 so as to supply cold air or warm air into the corresponding zone. As a kind of valve, it is connected to a control unit (not shown) or manually operated so as to detect temperature or humidity of a corresponding region and compare the detected value with a set value to automatically turn on / off.

상기와 같은 영역조절기를 구비한 히트펌프형 유니터리 공기조화장치는 다음과 같이 동작한다.The heat pump type unitary air conditioner having the area controller as described above operates as follows.

즉, 2층 주택의 경우 각 층(해당 영역)(Z1,Z2)의 부하를 검출하여 그 부하가 설정값 이상이면 각각의 급기덕트(3)를 통해 냉풍 또는 온풍을 동시에 공급하는 반면 그 중 어느 한 쪽 영역만이 설정값 이상이면 해당 영역(Z1,Z2)의 급기덕트(3)를 통해 냉풍 또는 온풍을 구분하여 공급한다.That is, in the case of a two-story house, the load of each floor (the corresponding area) Z1 and Z2 is detected and if the load is equal to or greater than the set value, the cold air or the warm air is simultaneously supplied through the respective air supply ducts 3 If only one region is greater than or equal to the set value, cold air or warm air is supplied separately through the air supply duct 3 of the corresponding areas Z1 and Z2.

예컨대, 냉방운전시에는 실외기(1)의 압축기(1a)가 구동하여 냉매가스를 압축하고, 이 냉매가스는 실외기(1)의 제1 열교환기(1b)에서 응축되어 팽창기구(1c)를 통과한 후 냉온풍기(2)의 제2 열교환기(2a)를 거치면서 배기덕트(4)를 통해 공기유로로 흡입된 공기와 열전달하여 냉기를 발생하며, 이 냉기는 급기팬(미도시)에 의해 급기구를 통해 급기덕트(3)로 이동한다. 이때, 각 층(Z1,Z2)의 부하가 모두 설정값 이상이면 자동인 경우 제어부에 의해 자동으로 각 영역조절기(5a~5d)가 온(ON)되고 수동인 경우 사용자의 조작에 의해 각 영역조절기(5a~5d)를 열어 냉온풍기(2)에서 생성된 냉기가 상기한 각각의 급기덕트(3)로 이동하면서 각 층을 냉방하는 것이다. 반면, 어느 한 층(Z1,Z2)의 부하가 설정값 이하인 경우에는 부하가 높은 쪽의 영역조절기만 자동 또는 수동으로 열어 냉기가 해당 영역의 급기덕트(3)로만 이동하도록 하여 해당 층을 냉방하는 것이다. For example, during the cooling operation, the compressor 1a of the outdoor unit 1 is driven to compress the refrigerant gas, which is condensed in the first heat exchanger 1b of the outdoor unit 1 and passes through the expansion mechanism 1c. Then, while passing through the second heat exchanger (2a) of the cold and hot air fan (2), heat is transferred to the air sucked into the air flow path through the exhaust duct (4) to generate cold air, this cold air by an air supply fan (not shown) It moves to the air supply duct (3) through the air supply port. At this time, if the load of each layer (Z1, Z2) is more than the set value, each area controller (5a ~ 5d) is automatically turned on (ON) by the control unit in the case of automatic and each area controller by the user's operation in the case of manual 5a to 5d are opened to cool each layer while the cool air generated in the cold / hot air fan 2 moves to each of the air supply ducts 3 described above. On the other hand, if the load of any one floor (Z1, Z2) is below the set value, only the zone controller of the higher load is automatically or manually opened so that the cold air moves only to the air supply duct (3) of the corresponding zone. will be.

한편, 난방운전시에도 동일하나 다만 냉매의 순환이 히트펌프형 냉동사이클에 따라 역순으로 진행된다.On the other hand, the same in the heating operation, but the circulation of the refrigerant proceeds in the reverse order according to the heat pump type refrigeration cycle.

여기서, 상술한 유니터리 공기조화장치는, 도3과 같이, 실내에 위치한 써모스태트가 실내 정보(실내온도와 희망온도의 차이)를 이용하여 실내기와 실외기를 제어한다.Here, in the unitary air conditioner described above, as shown in FIG. 3, the thermostat located indoors controls the indoor unit and the outdoor unit using indoor information (difference between the indoor temperature and the desired temperature).

즉, 실내 부하변수에 의해 계산된 정보 Y1,Y2(압축기의 온/오프 제어신호)에 의해 실내기와 실외기를 최소운전 또는 최대운전으로 제어한다.That is, the indoor unit and the outdoor unit are controlled to the minimum operation or the maximum operation by the information Y1, Y2 (on / off control signal of the compressor) calculated by the indoor load variable.

이때, 상술한 종래 유니터리 공기조화장치는, 싱글모델인 경우, 써모스태트에서 운전신호인 실내기 및 실외기에서 정해진 운전(최대운전)만을 수행하게 되고, 2-스테이지(stage) 모델의 경우, 써모스태트에서 최대운전 신호인 Y2신호가 발생하면, 실내기와 실외기는 모두 최대운전을 수행하고, 상기 써모스태트에서 최소운전신호인 Y1신호가 발생하면 실내기와 실외기는 모두 최소운전을 수행하게 된다.In this case, the conventional unitary air conditioner described above, in the case of a single model, performs only a predetermined operation (maximum operation) in the indoor unit and the outdoor unit which are driving signals in the thermostat, and in the case of a two-stage model, the thermostat When the Y2 signal, which is the maximum operation signal, is generated, both the indoor unit and the outdoor unit perform maximum operation. When the Y1 signal, which is the minimum operation signal, is generated by the thermostat, both the indoor unit and the outdoor unit perform the minimum operation.

상술한 바와같이, 종래 유니터리 공기조화장치는, 용량이 다른 두개의 압축기를 사용함에도 불구하고, 최대 두 단계만으로 부하에 대응하므로, 부하대응능력이 저하됨과 아울러 소비전력이 증가되고, 또한 사용자가 느끼는 쾌적감이 저하되는 단점이 있다.As described above, the unitary air conditioner according to the related art responds to the load in only two stages, even though two compressors having different capacities are used, so that the load-response ability is reduced and power consumption is increased. There is a disadvantage in that comfort is reduced.

도4에 도시한 바와같이 본 발명은, 사용자가 냉방모드를 선택하면, 약냉신호 를 발생하는데, 이때 써모스태트의 종류에 따라, 초기에 강냉신호를 발생하는 경우도 있으며, 이와같이 초기에 강냉신호를 발생하는 경우의 본 발명의 다른 실시예의 알고리즘은 후술한다.As shown in FIG. 4, when the user selects the cooling mode, the user generates a weak cooling signal. At this time, a strong cooling signal may be generated initially depending on the type of the thermostat. An algorithm of another embodiment of the present invention in case of occurrence will be described later.

우선, 써모스태트는, 초기 기동시 약냉신호를 발생하고, 그 약냉신호에 의해 대용량 압축기를 운전시킨다.First, the thermostat generates a weak cooling signal at the time of initial start-up, and operates the large capacity compressor by the weak cooling signal.

이후, 실내의 부하가 해소되는 일정시간이 경과되면, 실내온도와 희망온도를 비교하고, 그 비교결과에 의해 써모스태트가 강냉신호를 발생하기 위한 압축기 온/오프제어신호(Y2)를 발생하면 소용량 및 대용량 압축기를 모두 운전시켜 실내 부하를 해소한다.Then, when a certain time elapses when the indoor load is released, the indoor temperature is compared with the desired temperature, and when the thermostat generates the compressor on / off control signal Y2 for generating a strong cooling signal, And all the large-capacity compressors are operated to relieve indoor load.

그 다음, 상기 소용량 및 대용량 압축기를 운전시키다가, 일정시간 경과하면, 다시 실내온도와 희망온도를 비교하고, 그 비교결과에 의해 써모스태트가 약냉을 발생하기 위한 압축기 온/오프제어신호(Y1)를 발생하면 대용량 압축기를 운전시킨다.Then, while the small-capacity and large-capacity compressors are operated, after a certain period of time, the indoor temperature and the desired temperature are again compared, and according to the comparison result, the compressor on / off control signal Y1 for the thermostat to generate weak cooling is performed. If it generates, operate the large capacity compressor.

이렇게, 대용량 압축기를 운전시키다가, 일정시간 경과하면, 실내온도와 희망온도를 비교하고, 그 비교결과에 근거하여 써머스태트가 압축기 운전 발생정지를 위한 압축기 온/오프제어신호를 발생하면 대용량 압축기의 운전을 정지시키고, 다시 일정시간후, 써모스태트에 의해 약냉 발생을 위한 압축기 온/오프제어신호(Y1)가 발생하면 소용량 압축기를 운전시킨다.When the large-capacity compressor is operated and a predetermined time has elapsed, the indoor temperature and the desired temperature are compared, and based on the comparison result, when the thermostat generates the compressor on / off control signal for stopping the compressor operation, the large-capacity compressor When the operation is stopped and again after a certain time, when the compressor on / off control signal Y1 for generating the weak cooling is generated by the thermostat, the small capacity compressor is operated.

즉, 써모스태트가 약냉신호(Y1)를 발생한후 정지신호를 발생하고, 다시 약냉신호(Y1)를 발생하면 소용량 압축기만 운전시키는데, 즉 어느 정도 부하가 해소된 것으로 판단하여 최소운전을 실행한다.That is, when the thermostat generates the weak cooling signal Y1 and generates the stop signal, and generates the weak cooling signal Y1 again, only the small capacity compressor is operated, that is, it is determined that the load is released to some extent and the minimum operation is executed.

따라서, 이후로는 실내부하가 어느정도 해소된 것으로 판단하여 약냉신호(Y1) 발생시 소용량 압축기만을 운전시킨다.Therefore, afterwards, it is determined that the indoor load is somewhat eliminated, and only the small capacity compressor is operated when the weak cooling signal Y1 is generated.

즉, 상기 소용량 압축기를 운전시키다가, 다시 일정시간 경과후, 실내온도와 희망온도를 비교하고, 그 비교결과에 근거하여 써머스태트가 압축기 운전발생정지를 위한 압축기 온/오프제어신호를 발생하면 소용량 압축기의 운전을 정지시키고, 다시 일정시간후, 써모스태트에 의해 약냉신호(Y1) 발생을 위하여 압축기 온/오프제어신호가 발생하면 소용량 압축기를 운전시킨다.That is, after operating the small capacity compressor again, after a certain period of time, the room temperature and the desired temperature are compared, and based on the comparison result, if the thermostat generates a compressor on / off control signal for stopping the compressor operation, the small capacity After the compressor is stopped, and after a certain time, when the compressor on / off control signal is generated to generate the weak cooling signal Y1 by the thermostat, the small capacity compressor is operated.

한편, 상기 소용량 및 대용량 압축기를 운전시키다가, 일정시간 경과후, 실내온도와 희망온도를 비교하고, 그 비교결과에 의해, 써모스태트가 압축기 운전 발생 정지를 위한 압축기 온/오프제어신호를 발생하면, 대용량 및 소용량 압축기의 운전을 정지시키고, 이렇게 대용량 및 소용량 압축기의 운전을 정지시키다가, 일정시간 경과하면, 실내온도와 희망온도를 비교하고, 그 비교결과에 의해 써모스태트가 약냉신호(Y1) 발생을 위한 압축기 온/오프제어신호를 발생하면, 대용량 압축기를 운전시킨다.On the other hand, while operating the small-capacity and large-capacity compressor, after a certain period of time, the room temperature and the desired temperature is compared, and when the thermostat generates a compressor on / off control signal for stopping the compressor operation, After stopping the operation of the large capacity and small capacity compressors, and stopping the operation of the large capacity and small capacity compressors, and after a certain period of time, the indoor temperature and the desired temperature are compared, and the thermostat shows the weak cooling signal (Y1). When the compressor on / off control signal for generation is generated, the large capacity compressor is operated.

즉, 강냉신호에 의해 대용량 압축기 및 소용량 압축기로 운전하다가, 일정시간 경과하여 부하가 해소되어 약냉신호가 발생하거나, 일정시간 동안 압축기가 정지된후 약냉신호가 발생하면, 대용량 압축기를 운전시켜 부하를 해소한다.In other words, when the low-cooling signal is operated by the large-capacity compressor and the small-capacity compressor and the load is released after a certain period of time, a weak cooling signal is generated, or when the weak cooling signal is generated after the compressor is stopped for a certain time, the large capacity compressor is operated to load the load. Eliminate

도5는 본 발명 유니터리 공기조화기의 운전제어방법에 대한 다른 실시예의 동작흐름도이다.5 is a flowchart illustrating another embodiment of the operation control method of the unitary air conditioner of the present invention.

도5에 도시한 바와같이 본 발명은,사용자에 의해, 냉방모드가 선택되면, 써모스태트에서 강냉신호(기설정된 신호)를 발생하고, 그 강냉신호에 의해 소용량 및 대용량 압축기를 운전시킨다.As shown in Fig. 5, in the present invention, when the cooling mode is selected by the user, a strong cooling signal (preset signal) is generated in the thermostat, and the small capacity and large capacity compressors are driven by the strong cooling signal.

상기 소용량 및 대용량 압축기를 운전시키다가, 일정시간이 경과하면, 실내온도와 희망온도를 비교하고, 그 비교결과에 의해 써모스태트가 압축기 운전 발생정지를 위한 압축기 온/오프제어신호를 발생하면, 상기 소용량 및 대용량의 압축기의 운전을 정지시킨다.When the small-capacity and large-capacity compressors are operated and a predetermined time has elapsed, the indoor temperature and the desired temperature are compared, and when the thermostat generates a compressor on / off control signal for stopping the compressor operation, Stop the operation of small and large capacity compressors.

그 다음, 상기 소용량 및 대용량 압축기를 운전 정지시키다가, 일정시간 경과하면, 실내온도와 희망온도를 비교하고, 그 비교결과에 의해 써모스태트가 약냉신호를 발생하기 위한 압축기 온/오프 제어신호를 발생하면 대용량 압축기를 운전시킨다.Then, after stopping the small-capacity and large-capacity compressors, a predetermined time elapses, the indoor temperature and the desired temperature are compared, and the thermostat generates a compressor on / off control signal for generating a weak cooling signal. To operate the large-capacity compressor.

만약, 상기 소용량 및 대용량 압축기를 운전시키다가, 일정시간 경과하면, 실내온도와 희망온도를 비교하고, 그 비교결과에 근거하여 써모스태트가 약냉 발생을 위한 압축기 온/오프 제어신호를 발생하면, 대용량 압축기를 운전시킨다.If the small-capacity and large-capacity compressors are operated and after a certain period of time, the indoor temperature and the desired temperature are compared, and based on the comparison result, if the thermostat generates a compressor on / off control signal for weak cooling generation, Run the compressor.

그 다음, 상기 대용량 압축기를 운전시키다가, 일정시간 경과하면, 실내온도와 희망온도를 비교하고, 그 비교결과에 근거하여 써모스태트가 압축기 운전발생정지를 위한 압축기 온/오프제어신호를 발생하면, 대용량 압축기 운전을 정지시키고, 다시 일정시간 경과후, 실내온도와 희망온도를 비교하고, 그 비교결과에 근거하여 써모스태트가 약냉발생을 위한 압축기 온/오프 제어신호를 발생하면 소용량 압축기를 운전시킨다.Then, after operating the large-capacity compressor for a predetermined time, the room temperature and the desired temperature are compared, and if the thermostat generates a compressor on / off control signal for stopping the compressor operation based on the comparison result, After the operation of the large capacity compressor is stopped, and after a certain time has elapsed, the indoor temperature is compared with the desired temperature, and the small capacity compressor is operated when the thermostat generates a compressor on / off control signal for weak cooling based on the comparison result.

여기서, 도6은 본 발명과 종래에 의한 실내공기온도를 보인 그래프로서, 전체적으로 실내온도의 변동폭이 종래보다 작음을 알 수 있다.Here, Figure 6 is a graph showing the indoor air temperature according to the present invention and the prior art, it can be seen that the fluctuation range of the indoor temperature as a whole less than the conventional.

본 발명은 부하에 따라 약냉신호에 따른 압축기의 운전방식을 달리하는 것으로, 즉 강냉신호에 의해, 대용량 및 소용량 압축기를 운전시키다가, 약냉신호가 발생하거나, 부하가 해소되어 정지된 다음 일정시간이 지나 약냉신호가 발생하면 대용량 압축기만 운전시키고, 약냉신호에 의해 대용량 압축기만 운전시키다가, 부하가 해소되어 정지된 다음,일정시간이 지나 약냉신호가 발생하면 소용량 압축기만을 운전시키도록 한 것이다.According to the present invention, the operation method of the compressor according to the weak cooling signal is changed according to the load. That is, while the large and small capacity compressors are operated by the strong cooling signal, the weak cooling signal is generated, or the load is released and then stopped for a predetermined time. When the low-cooling signal is generated, only the large-capacity compressor is operated, and the high-capacity compressor is operated only by the low-cooling signal. Then, the load is released and stopped. After a predetermined time, the low-cooling signal is generated.
