본 발명은 열펌프 공기조화기의 고온풍토출제어방법 및 그 장치에 관한 것으로, 특히 외기 온도가 하강해도 실내에 고온풍을 토출하게 하여 쾌적 난방을 유지할 수 있는 열펌프 공기조화기의 고온풍토출제어방법 및 그 장치에 관한 것이다.The present invention relates to a hot air discharge control method and apparatus for a heat pump air conditioner, and particularly, a hot air discharge agent of a heat pump air conditioner capable of maintaining comfortable heating by discharging hot air into the room even when the outside air temperature decreases. It relates to a fishery and its apparatus.

일반적으로 열펌프 공기조화기는 냉방과 난방을 동시에 할 수 있는 것으로, 종래의 열펌프 공기조화기의 난방 사이클은, 도 1에 도시한 바와 같이, 저온 저압의 기체 상태의 냉매를 고온 고압으로 변화시키는 압축기(1)와, 상기 압축기(1)에서 나온 고온 고압의 냉매를 응축시키는 실내열교환기(2)와, 상기 실내열교환기(2)의 열교환을 돕도록 설치되는 실내팬(4)과, 상기 실내열교환기(2)에서 고온 고압의 액체 냉매를 저온 저압의 2상 냉매로 팽창시키는 팽창 장치(5a)와, 상기 팽창 장치(5a)에서 나온 2상 냉매를 기체 상태로 증발시키면서 외부의 열을 흡수하는 실외열교환기(6)와, 상기 실외열교환기(6)의 열교환을 돕도록 설치되는 실외팬(8)과, 시스템의 냉난방을 절환시키는 4방향 밸브(1a)로 구성된다.In general, the heat pump air conditioner is capable of cooling and heating at the same time, the heating cycle of the conventional heat pump air conditioner, as shown in Figure 1, to change the refrigerant in the gas state of low temperature low pressure to high temperature high pressure A compressor (1), an indoor heat exchanger (2) for condensing the high temperature and high pressure refrigerant from said compressor (1), an indoor fan (4) installed to help heat exchange between said indoor heat exchanger (2), and In the indoor heat exchanger (2), an expansion device (5a) for expanding a high-temperature, high-pressure liquid refrigerant into a low-temperature, low-pressure two-phase refrigerant, and external heat is evaporated while evaporating the two-phase refrigerant from the expansion device (5a) in a gaseous state. It consists of an outdoor heat exchanger (6) which absorbs, an outdoor fan (8) installed to help heat exchange of the outdoor heat exchanger (6), and a four-way valve (1a) for switching the heating and cooling of the system.

미설명 부호 3은 실내팬(4)을 회전시키는 실내팬 모터이고, 7은 실외팬(8)을 회전시키는 실외팬 모터이다.Reference numeral 3 is an indoor fan motor for rotating the indoor fan 4, 7 is an outdoor fan motor for rotating the outdoor fan (8).

상기와 같은 구성의 열펌프 공기조화기의 작동상태를 설명하면 다음과 같다.Referring to the operating state of the heat pump air conditioner of the above configuration as follows.

압축기(1)에서 나온 고온 고압의 냉매는 4방향 밸브(1a)에서 실내기로 절환되어 실내측에 위치한 실내열교환기(2)를 통햐여 응축된 후 팽창 장치(5a)에서 팽창되어 저온 저압의 냉매로 되어 증발하기 좋은 상태로 된다.The high temperature and high pressure refrigerant from the compressor (1) is switched to the indoor unit by the four-way valve (1a) and condensed through the indoor heat exchanger (2) located on the indoor side, and then expanded in the expansion device (5a) to cool the low pressure and low pressure refrigerant. It will be in a good state to evaporate.

실외열교환기(6)에서 증발을 통하여 열을 흡수한 냉매는 다시 어큐물레이터(9)를 지나 압축기(1)로 보내져 압축하는 과정을 반복하면서 난방 기능을 수행한다.The refrigerant absorbing heat through evaporation in the outdoor heat exchanger (6) passes the accumulator (9) to the compressor (1) and performs a heating function while repeating the compression process.

첨부한 도 2는 난방 표준온도 조건에서의 열펌프 공기조화기의 난방 운전 사이클과 외기 온도가 하강하여 저온 조건에서의 열펌프 공기조화기의 난방 운전 사이클을 비교도시한 선도이다.2 is a diagram illustrating a comparison of the heating operation cycle of the heat pump air conditioner in the heating standard temperature condition and the heating operation cycle of the heat pump air conditioner in the low temperature condition due to the decrease in the outside air temperature.

난방 표준 온도 조건(15,16)에서의 사이클(17)은 그 고압측이 실내 표준온도(15)보다 항상 높아야 하고 저압측은 실외 표준온도(16)보다 항상 낮아야 증발과 응축을 할 수 있는 사이클이 형성된다.In the heating standard temperature condition (15, 16), the cycle (17) must have its high pressure side always higher than the indoor standard temperature (15) and the low pressure side should always be lower than the outdoor standard temperature (16) to allow the cycle to evaporate and condense. Is formed.

외부의 기온이 낮아져서 실외측 온도(14)가 0℃이하로 하강하면 실내측 온도(13)도 외기 부하의 증가로 인해 하강한다.When the outside temperature is lowered and the outdoor side temperature 14 falls below 0 ° C., the indoor side temperature 13 also falls due to the increase in the outside air load.

이때. 난방 사이클의 고압과 저압의 차이(12)는 거의 변하지 않는 특성이 있으므로, 상기와 같이 외기 온도가 낮아지면 저온시의 새로운 사이클(18)이 형성된다.At this time. Since the difference 12 between the high pressure and the low pressure of the heating cycle is almost unchanged, a new cycle 18 at low temperature is formed when the outside air temperature is lowered as described above.

일반적으로 표준 온도 조건에서 실내측의 응축 온도는 45℃를 유지하고, 실외는 1℃를 유지한다.In general, the condensation temperature at the indoor side is maintained at 45 ℃ under standard temperature conditions, and 1 ℃ in the outdoor.

이때, 실내측에서 열교환을 하면 40℃정도의 온풍을 얻을 수 있게 된다.At this time, if the heat exchange in the indoor side it is possible to obtain a warm air of about 40 ℃.

그러나, 실외측의 온도가 0℃이하로 하강하면 증발 온도는 -5℃ 이하가 되고 실내측 응축 온도는 41℃정도가 되어 결과적으로 실내 토출공기 온도를 40℃로 유지하기 어렵게 된다.However, when the temperature on the outdoor side drops below 0 ° C., the evaporation temperature is -5 ° C. or less, and the indoor condensation temperature is about 41 ° C., which makes it difficult to maintain the indoor discharge air temperature at 40 ° C.

이때, 실내에는 약 36℃정도의 차가운 공기가 토출되어 냉출토출현상이 발생하고여 실내의 사용자로 하여금 난방 불쾌감을 느끼게 한다.At this time, the cold air of about 36 ℃ is discharged in the room to generate a cold air discharge phenomenon to make the user of the interior feel uncomfortable heating.

종래에는 상기와 같은 문제점을 방지하기 위해서 추운 날씨가 계속되면 실외온도 감지 센서의 감지에 따라 실내측의 풍량을 감소시켜 응축 온도를 45℃정도까지 높임으로써, 실내의 온풍을 유지하는 제어를 통해 난방 운전하였다.Conventionally, in order to prevent the above problems, if the cold weather continues, the indoor air volume is reduced according to the detection of the outdoor temperature sensor and the condensation temperature is increased to about 45 ° C., thereby controlling the heating of the indoor air. Drive.

그러나, 외기온이 0℃ 이하일 경우에는 실내 풍량의 감소만으로는 40℃정도의 고온풍을 얻을 수 없으며, 실내 풍량 감소로 인해 열량이 저하하여 보조 열원 사용에 따른 추가 비용 발생하는 문제점이 있었던바, 이에 대한 보완이 요구되어 왔다.However, when the outside air temperature is 0 ° C or less, high temperature winds of about 40 ° C cannot be obtained only by the reduction of the indoor air volume.Therefore, there is a problem in that additional heat is generated due to the decrease in the amount of heat due to the decrease in the indoor airflow. Supplementation has been required.

따라서, 본 발명은 상기와 같은 문제점을 감안하여 안출한 것으로서, 실외온이 0℃이하로 내려가면 실외측 풍량을 증가시키고 실내 풍량은 감소시킴과 동시에 저유량 의 냉매를 팽창시킬 수 있는 저유량용 팽창장치를 적용하여 궁극적으로 실내 고온풍을 유지할 수 있게 한 열펌프 공기조화기의 고온풍토출제어방법 및 그 장치를 제공하는데 그 목적이 있다.Therefore, the present invention has been devised in view of the above problems, and when the outdoor temperature falls below 0 ° C., the outdoor air volume increases, the indoor air volume decreases, and at the same time, a low flow rate refrigerant can be expanded. It is an object of the present invention to provide a hot air discharge control method and a device for a heat pump air conditioner that can maintain an indoor hot air by applying an expansion device.

난방 운전이 시작되면 시스템에 설치된 감지 수단이 외기온도와 응축온도를 감지하고, 감지된 외기 온도가 0℃이하이거나 응축 온도가 42℃이하면 방향절환 전자밸브(11)를 저유량용의 제 2 팽창 장치(10)로 절환하여 고온풍 토출 운전 모드로 전환시킨다.When the heating operation is started, the sensing means installed in the system detects the outside temperature and the condensation temperature, and when the detected outside temperature is below 0 ° C or the condensation temperature is below 42 ° C, the directional expansion solenoid valve 11 is expanded for the second flow for low flow rate.
