본 발명의 전기 가열기(50)는 도 4 내지 도 6 에 도시 된 바와같이 다단설치된 발열봉(51) 외측에 방열핀(52)을 부착시켜 열방출이 용이하게 하고, 방열봉(51)의 내부는 열원인 반도전성 폴리머(53)를 양측에 설치하고 내부는 열매체유(54)를 채워 구성한다.As shown in FIGS. 4 to 6, the electric heater 50 of the present invention attaches the heat dissipation fins 52 to the outside of the multi-stage heating rod 51 to facilitate heat dissipation.

본 발명의 전체 구성도는 도 2 에 도시된 바와같이 냉방시는 압축기(10)에서 압축된 냉매가 솔레노이드밸브(11)를 거쳐 가습보조응축기(20)와 응축기(21)를 거친 후 보조냉각기(22)와 팽창밸브(25)를 거치고 증발기(30)를 거친 후 보조냉각기(22)를 거쳐 압축기(10)로 흐르게 되고, 난방시는 압축기(10)에서 압축된 냉매가 솔레노이드밸브(12)를 거쳐 증발기(22)를 거친 후 팽창밸브(25)와 보조냉각기(22)를 거쳐 응축기(21)로 흐른 후 증발기(30)에 일체로 형성된 가열보조응축기(40)를 거치고 보조냉각기(22)를 거쳐 압축기(10)로 흐르게 구성된다.The overall configuration of the present invention, as shown in Figure 2 during cooling the refrigerant compressed in the compressor 10 passes through the solenoid valve 11 through the humidification subcondenser 20 and the condenser 21 after the auxiliary cooler ( 22) and the expansion valve (25), after passing through the evaporator (30) and through the subcooler (22) flows to the compressor (10), during heating, the refrigerant compressed in the compressor (10) is the solenoid valve (12) After passing through the evaporator 22 and flows through the expansion valve 25 and the subcooler 22 to the condenser 21 through the heating auxiliary condenser 40 integrally formed in the evaporator 30, the sub-cooler 22 It is configured to flow to the compressor 10 via.
여기서 보조 냉각기(22)는 이중파이프로 구성되어 응축기(21) 또는 팽창밸브(25)를 거친 냉매가 내측을 흐르게 하고 증발기(30) 또는 가열보조응축기(40)를 거친 냉매가 외측을 흐르게 하여 냉방에 사용 될 냉매를 냉각시키도록 한다.Here, the auxiliary cooler 22 is composed of a double pipe so that the refrigerant passing through the condenser 21 or the expansion valve 25 flows inward and the refrigerant passing through the evaporator 30 or the auxiliary heating condenser 40 flows outward. To cool the refrigerant to be used.
보조 냉각기(22)를 거친 냉매는 필터 드라이어(15)와 솔레노이드 밸브(16)를 거친 후 팽창밸브(25)에서 분배기(28)로 인가되게 하거나, 솔레노이드 밸브(26)와 수동팽창 밸브(27)를 거쳐 분배기(28)를 인가되게 구성한다.The refrigerant passing through the subcooler 22 is applied to the distributor 28 from the expansion valve 25 after passing through the filter drier 15 and the solenoid valve 16 or the solenoid valve 26 and the manual expansion valve 27. Through the distributor 28 is configured to be applied.
이와같은 본 발명의 항온공조기(1)는 냉난방에 사용될 수 있도록 한 것으로, 냉방시에는 압축기(10)의 냉매가 응축기(21)와 팽창밸브(25)및 증발기(30)를 거쳐 압축기(10)로 흐르게 하고, 난방시는 압축기(10)의 냉매가 증발기(30)와 팽창밸브(25)및 응축기(21)를 거친 후 가열보조응축기(40)를 거쳐 압축기(10)로 흐르게 한다.Such a constant temperature air conditioner (1) of the present invention is to be used for heating and cooling, during cooling the refrigerant of the compressor 10 through the condenser 21, the expansion valve 25 and the evaporator 30, the compressor (10) In the heating, the refrigerant of the compressor 10 passes through the evaporator 30, the expansion valve 25, and the condenser 21, and then flows through the heating auxiliary condenser 40 to the compressor 10.
본 발명의 냉방 작동시를 살펴본다.It looks at the cooling operation of the present invention.
냉방시는 솔레노이드 밸브(11)(16)는 개방되고, 솔레노이드 밸브(12)(26)는 폐쇄된 상태가 된다.At cooling, the solenoid valves 11 and 16 are opened, and the solenoid valves 12 and 26 are closed.
그러면 압축기(10)에서 압축된 냉매는 가습보조 응축기(20)를 거쳐 물탱크(74)의 물을 가온시키게 되고 응축기(21)를 거쳐 냉매를 식힌 후 다시 보조 냉각기(22)에서 재차 냉매를 식혀준 후 팽창 밸브(25)에서 팽창시켜 분배기(28)에서 증발기(30)로 공급하므로써 증발기(30)에서 실내공기의 온도를 낮추어 준 후 송풍팬(6)으로 배출시켜 실내온도를 낮추어 주게 되며, 응축기(21)를 거치면서 덮혀진 공기는 배기구(7)를 거쳐 외부로 배출되게 한다.Then, the refrigerant compressed by the compressor 10 warms the water in the water tank 74 through the humidification subsidiary condenser 20, cools the refrigerant through the condenser 21, and then cools the refrigerant again in the auxiliary cooler 22. After the expansion by expanding from the expansion valve 25 to supply the evaporator 30 from the distributor 28 to lower the temperature of the indoor air in the evaporator 30 and then discharged to the blower fan 6 to lower the room temperature, The air covered while passing through the condenser 21 is discharged to the outside via the exhaust port (7).
이 때 덕트(45)의 차단판(46)은 응축기(21)를 거친 공기가 배기구(7)로 흐르게 절환시켜 놓게 된다.At this time, the blocking plate 46 of the duct 45 switches the air passing through the condenser 21 to the exhaust port 7.
상기된 증발기(30)의 작동시 실내공기에 포함된 수분은 증발기(30)표면에서응축되어 응축수로 떨어지게 되며 이 때의 응축수는 배수구(73)에서 물탱크(74)로 모아지게 된다.The moisture contained in the indoor air during the operation of the evaporator 30 is condensed on the surface of the evaporator 30 to fall into the condensate, and the condensate at this time is collected from the drain 73 to the water tank 74.
한편 증발기(30)작동중에 실내습도가 떨어지는 경우가 발생하면 가습보조 응축기(20)를 작동시켜 물탱크(74)의 물을 가온시켜 응축수를 증발시키게 하고 가습보조응축기(20)에 의해 증발된 증기는 가습관(71)을 거친 후 송풍팬(73)에 의해 실내로 유입되어 실내습도를 높히도록 하는데, 물탱크(74)에서 증발된 증기가 유입되는 가습관(71)의 선단부에는 소형 송풍팬(73)을 장착해 증기가 용이하게 실내로 유입될 수 있도록 한다.On the other hand, if the room humidity drops during operation of the evaporator 30, the humidification auxiliary condenser 20 is operated to warm the water in the water tank 74 to evaporate the condensed water and the vapor evaporated by the humidification auxiliary condenser 20. After passing through the humidifying tube 71 is introduced into the room by the blowing fan 73 to increase the indoor humidity, a small blowing fan at the tip of the humidifying tube 71 in which the vapor evaporated from the water tank 74 is introduced (73) is fitted so that steam can easily enter the room.
다음으로 난방시를 살펴본다.Next, look at the heating time.
이 때 솔레노이드 밸브(11)는 닫고 솔레노이드 밸브(12)를 열어 준다.At this time, the solenoid valve 11 is closed and the solenoid valve 12 is opened.
그러면 압축기(10)의 냉매는 증발기(30)로 유입되어 증발기(30)가 냉방시의 응축기 역할을 하도록 하고, 증발기(30)를 거친 냉매는 팽창밸브(25)를 거치고 보조냉각기(22)를 거친 후 응축기(21)에 인가되어 응축기(21)가 냉방시의 증발기 역할을 하도록 하며, 응축기(21)를 거친 냉매는 가열보조응축기(40)에서 냉매온도를 상승시킨 후 가열보조냉각기(22)를 거쳐 압축기(10)로 흐르게 된다.Then, the refrigerant of the compressor 10 flows into the evaporator 30 so that the evaporator 30 serves as a condenser during cooling, and the refrigerant passing through the evaporator 30 passes through the expansion valve 25 and the auxiliary cooler 22. After coarse, the condenser 21 is applied to the condenser 21 to serve as an evaporator during cooling, and the refrigerant passing through the condenser 21 increases the refrigerant temperature in the heating auxiliary condenser 40 and then the heating auxiliary cooler 22. It passes through the compressor 10 through.
난방시 압축기(10)에서 압축된 냉매는 증발기(30)로 유입되어 증발기(30)가 응축기 역할을 하여 더운 바람이 송풍되게 되고, 증발기(30)를 거치고 응축기(21)를 거친 냉매는 차가워지게 되어 그대로 압축기(10)로 유입시키면 기온이 차가운 겨울철에는 압축기(10)에서 적정압력(15㎏/㎠)으로 냉매를 압축시키지 못하여 냉매 싸이클이 정상작동되지 않으므로, 본 발명에서는 응축기(21)에서 냉각된 냉매가 증발기(30)와 일체로 형성된 가열보조응축기(40)를 거치면서 증발기(30)의 열로 냉매를 덮혀주도록 하므로써 겨울철에도 압축기(10)에서 적정압력으로 냉매를 압축시킬 수 있도록 한다.During heating, the refrigerant compressed by the compressor 10 flows into the evaporator 30 so that the evaporator 30 functions as a condenser so that hot wind is blown, and the refrigerant passing through the evaporator 30 and passing through the condenser 21 is cooled. If the air flows into the compressor 10 as it is, the refrigerant cycle cannot be compressed at a proper pressure (15 kg / cm 2) in the compressor 10 in the winter when the temperature is cold, and thus the refrigerant cycle does not operate normally. In the present invention, the condenser 21 is cooled in the condenser 21. Through the heating auxiliary condenser 40 formed integrally with the evaporator 30 to cover the refrigerant by the heat of the evaporator 30, the refrigerant can be compressed in the compressor 10 at an appropriate pressure even in winter.
따라서 난방시 증발기(30)가 응축기와 같이 열을 발산시키게 되어 난방이 가능토록 하는 한편 가열보조응축기(40)를 흐르는 냉매를 가온시켜 겨울철에 압축기(10)가 얼지 않으면서도 정상적인 냉매 압축 작용을 하도록 한다.Therefore, during heating, the evaporator 30 dissipates heat like a condenser so that heating is possible, while heating the refrigerant flowing through the heating auxiliary condenser 40 so that the compressor 10 does not freeze in winter and performs normal refrigerant compression. do.
이 때 증발기(30)의 배관과 가열보조응축기(40)의 배관이 밀착되게 설치하여 증발기(30) 배관에서 발생한 열로 난방을 행하는 동시에 가열보조응축기(40)의 배관을 흐르는 냉매를 가온시키도록 한다.At this time, the pipe of the evaporator 30 and the pipe of the heating auxiliary condenser 40 are installed in close contact with each other to heat the heat generated from the pipe of the evaporator 30 to heat the refrigerant flowing through the pipe of the heating auxiliary condenser 40. .
한편 가열보조응축기(40)만으로 냉매 온도를 높여주지 못할 정도이면 전기가열기(50)를 작동시켜 실내유입공기를 덮혀 주는 한편 냉매를 가온시켜 냉매압축이 정상적으로 이루어지도록 한다.On the other hand, if the heating auxiliary condenser 40 alone is not enough to increase the temperature of the refrigerant to operate the electric heater 50 to cover the indoor inlet air, while the refrigerant is heated to ensure that the refrigerant is compressed normally.
그리고 본 발명의 덕트(45)에 설치된 차단판(46)은 응축기(21)를 거친 공기가 외부 또는 실내로 유입되게 절환시킬 수 있는 것으로, 난방시는 응축기(21)를 거친 공기가 외부로 빠져나가도록 하되 실내 온도를 낮출 경우 실내로 유입되게 하여 실내온도를 낮추도록 한다.In addition, the blocking plate 46 installed in the duct 45 of the present invention can switch the air passing through the condenser 21 to the outside or the room, and during heating, the air passing through the condenser 21 falls out. If you want to go out, but lower the room temperature to enter the room to lower the room temperature.
전기 가열기(50)는 전기통전시 반도전성 폴리머(53)에서 열을 발생시켜 열매체유(54)를 가열시킴으로써 방열핀(52)이 부착 된 발열봉(51)을 통하여 열을 발산시키게 되고 실내 공기는 상기 전기 가열기(50)를 거치면서 원하는 온도로 상승되게 된다.The electric heater 50 generates heat from the semi-conductive polymer 53 during electric conduction to heat the heat medium oil 54 to dissipate heat through the heat generating rod 51 to which the heat dissipation fins 52 are attached. The electric heater 50 is raised to a desired temperature while passing.
한편 본 발명에서 냉방을 하면서 제습하는 경우를 살펴보면 다음과 같다.On the other hand look at the case of dehumidification while cooling in the present invention as follows.
냉방중일 경우도 제습을 하기 위해서는 가열보조 응축기(40)를 작동시키면 된다.In the case of cooling, in order to perform dehumidification, the heating auxiliary condenser 40 may be operated.
그러면 가열보조 응축기(40)가 작동하여 증발기(30)에서 실내공기를 냉각시키더라도 공기온도를 상승시킴으로써 제습 효과를 거둘 수 있도록 하며, 가열 보조응축기(40)로도 제습이 안되면 전기 가열기(50)를 작동시켜 제습이 이루어 지도록 한다.Then, the heating auxiliary condenser 40 operates to cool the indoor air in the evaporator 30 so that the air temperature is increased to achieve a dehumidifying effect. If the dehumidification is not possible even with the heating auxiliary condenser 40, the electric heater 50 is removed. Operate to allow dehumidification.
본 발명의 체크 밸브(13)는 냉매가 일방향으로 흐르게 하기 위하여 설치된다.The check valve 13 of the present invention is installed to allow the refrigerant to flow in one direction.
보조 냉각기(22)는 이중 파이프로 제작하여 응축기(21)를 거친 냉매가 내파이프로 흐르게 하고 그 외부를 증발기(30)를 거친 냉매가 흐르게 하여 냉매 온도를 낮출 수 있는 것으로 응축기(21)를 거친 냉매 온도보다 증발기(30)를 거친 냉매 온도가 낮기 때문에 가능하다.The auxiliary cooler 22 is made of a double pipe to allow the refrigerant passing through the condenser 21 to flow into the inner pipe and the refrigerant passing through the evaporator 30 to reduce the temperature of the refrigerant through the condenser 21. This is possible because the refrigerant temperature passing through the evaporator 30 is lower than the refrigerant temperature.
본 발명의 수동팽창 밸브(27)는 증발기(30)에 성애가 맺혔을 경우 이를 제거해줄 때 사용하는 것으로 증발기(30)에 성애가 맺히면 솔레노이드 밸브(26)를 열어주게 되고 그러면 증발기(30)에 유입되는 냉매의 속도를 낮추어 주게 되어 증발기(30)의 증발 효과를 낮춤으로써 성애를 제거해 주게 된다.The manual expansion valve 27 of the present invention is used to remove the frost when the evaporator 30 is formed. If the frost is formed on the evaporator 30, the solenoid valve 26 is opened and the evaporator 30 is then used. By lowering the speed of the refrigerant flowing into the evaporator 30 by lowering the evaporation effect is eliminated defrost.
수동 팽창밸브(27)는 수동으로 조작되며 한번 설정해 놓은 냉매 공급량을 유지하는 것으로, 냉매의 공급 유무는 솔레노이드 밸브(26)에 의하여 선택되게 된다.The manual expansion valve 27 is manually operated to maintain the refrigerant supply amount set once, and the presence or absence of the refrigerant supply is selected by the solenoid valve 26.
따라서 증발기(30)의 성애를 제거하기 위해서는 솔레노이드 밸브(26)를 개방시키면 되고, 냉매의 흐름 속도는 수동팽창밸브(27)에 의하여 선택되는 것이다.Therefore, in order to remove the defrost of the evaporator 30, the solenoid valve 26 may be opened, and the flow rate of the refrigerant is selected by the manual expansion valve 27.
본 발명은 일체형 항온 공조기에 있어서, 난방시 증발기로 냉매를 유입시켜 증발기가 냉방시의 응축기 역할을 하도록 하여 증발기를 통과한 공기 온도를 상승시켜 난방이 이루어지도록 하는 한편 가열보조응축기를 작동시켜 냉매온도가 되어진 후 압축기로 유입되게 하여 겨울철 냉매 온도가 낮아 적정압려으로 압축시키지 못하는 문제를 해결한 것이다.In the integrated constant temperature air conditioner, the refrigerant is introduced into the evaporator during heating so that the evaporator acts as a condenser during cooling, thereby raising the temperature of the air passing through the evaporator so that the heating is performed, while operating the heating auxiliary condenser, the refrigerant temperature. After it was introduced into the compressor to solve the problem of not being able to compress at the appropriate pressure due to the low refrigerant temperature in winter.
따라서 본 발명은 항온공조기를 냉,난방에 모두 사용할 수 있으며, 난방시 증발기를 거친 냉매를 이용하여 압축기로 유입되기 전의 냉매 온도를 높여 주도록 하여 열효율을 극대화시킬 수 있도록 하며, 난방시 응축기가 증발기 역할을 하게 되므로 증발기에 성애가 끼었을 때 간단하게 냉매의 흐름을 변화시켜 성애를 제거해 줄 수 있는 것이다.Therefore, the present invention can use both the constant temperature air conditioner for cooling and heating, and by using the refrigerant passed through the evaporator during heating to increase the refrigerant temperature before entering the compressor to maximize the thermal efficiency, the heating condenser acts as an evaporator Since it is possible to remove the frost by simply changing the flow of refrigerant when the frost is stuck in the evaporator.
