Abstract

The disclosed vehicular air conditioner converts blowing air to cool air by heat-exchange between a coolant and the blowing air and then discharges it to the interior of the vehicle. The coolant passes through a condenser, an expansion unit, and an evaporator in order, as a result of driving of a compressor, and then circulates through the compressor again. The blowing air is blown past the surface of the evaporator by a blower. In a vehicular seat and/or backrest, a tubular sub-evaporator is embedded, whereof one side is connected to the condenser and the other side is connected to the compressor. A sub-expansion unit converting the coolant to a low temperature and pressure can be placed between the sub-evaporator and evaporator. Since the sub-evaporator is installed in a vehicular seat and/or backrest, the present invention enables vehicular interior cooling as well as cooling the driver's seat and/or backrest, thereby a driver can drive comfortably.

도 2 내지 도 5를 참조하면, 차량용 공조 장치(100)는 압축기(110)와, 응축기(120)와, 팽창 장치(130)와, 증발기(140)와, 서브 팽창 장치(150) 및 서브 증발기(160)를 통해 냉매가 순환되고, 송풍기(미도시)에 의해 상기 증발기(140)를 통과한 공기가 차량 실내로 유입되며, 상기 서브 증발기(160)를 통과하는 냉매에 의해 차량 실내의 좌석 및/또는 등받이가 냉방된다.2 to 5, the vehicle air conditioner 100 includes a compressor 110, a condenser 120, an expansion device 130, an evaporator 140, a sub expansion device 150, and a sub evaporator. The refrigerant is circulated through the 160, and the air passing through the evaporator 140 is introduced into the vehicle interior by a blower (not shown), and the seat of the vehicle interior is cooled by the refrigerant passing through the sub-evaporator 160. And / or the backrest is cooled.

상기 압축기(110)와, 상기 응축기(120)와, 상기 팽창 장치(130) 및 상기 증발기(140)는 폐쇄 회로 형태일 수 있으며, 상기 서브 팽창 장치(150) 및 상기 서브 증발기(160)는 상기 응축기(120)로부터 분기되어 상기 압축기(110)에 연결되는 폐쇄 회로 형태일 수 있다.The compressor 110, the condenser 120, the expansion device 130 and the evaporator 140 may be in a closed circuit form, and the sub expansion device 150 and the sub evaporator 160 may be It may be in the form of a closed circuit branched from the condenser 120 and connected to the compressor 110.

즉, 상기 서브 팽창 장치(150) 및 상기 서브 증발기(160)는 상기 압축기(110)와 상기 응축기(120) 사이에서 병렬 연결될 수 있다.That is, the sub expansion device 150 and the sub evaporator 160 may be connected in parallel between the compressor 110 and the condenser 120.

이로 인해, 상기 응축기(120)를 거친 냉매는 상기 팽창 장치(130)와 상기 서브 팽창 장치(150)로 분기되어 공급될 수 있고, 상기 팽창 장치(130)를 통해 흐르는 냉매는 상기 증발기(140)에만 순수히 공급되어 차량 실내의 냉방에 사용되고, 상기 서브 팽창 장치(150)을 통해 흐르는 냉매는 상기 서브 증발기(160)에만 공급되어 차량의 좌석 및/또는 등받이가 냉방시키는 구조를 가진다.For this reason, the refrigerant having passed through the condenser 120 may be branched and supplied to the expansion device 130 and the sub expansion device 150, and the refrigerant flowing through the expansion device 130 may be supplied to the evaporator 140. Only the pure water is used to cool the vehicle interior, and the refrigerant flowing through the sub-expansion device 150 is supplied only to the sub-evaporator 160 to have a structure in which the seat and / or the back of the vehicle is cooled.

그리고, 상기 서브 증발기(160)는 관형 형상으로, 차량의 실내에 있는 좌석(171) 및/또는 상기 좌석(171)의 등받이(172)에 내에 설치된다.In addition, the sub-evaporator 160 has a tubular shape and is installed in the seat 171 and / or the backrest 172 of the seat 171 in the interior of the vehicle.

이 때, 상기 서브 증발기(160)는 차량 실내의 좌석(171) 혹은 등받이(172) 혹은 좌석(171)과 등받이(172) 모두에 설치될 수 있다.In this case, the sub evaporator 160 may be installed in the seat 171 or the backrest 172 or both the seat 171 and the backrest 172 of the vehicle interior.

상기 서브 증발기(160)는 그 길이가 1m ~ 9m 이내이고, 그 단면적은 0.8㎟ ~ 33㎟ 이내이다.The sub evaporator 160 has a length of 1 m to 9 m and a cross-sectional area of 0.8 mm 2 to 33 mm 2.

상기 단면적은 단면 형상에 관계없이 상기 서브 증발기(160)의 단면적을 의미하는 것으로, 상기 서브 증발기(160)의 전 범위에 걸쳐 상기 단면적은 0.8㎟ ~ 33㎟ 이내로 유지되어야 한다.The cross-sectional area means the cross-sectional area of the sub evaporator 160 regardless of the cross-sectional shape, and the cross-sectional area should be maintained within 0.8 mm 2 to 33 mm 2 over the entire range of the sub evaporator 160.

상기와 같은 서브 증발기(160)의 길이 및 그 단면적의 값은 상기 냉매의 흐름을 방해하지 않고, 길이에 따른 냉매의 압력 강하를 고려하여 설정될 수 있다.The length of the sub evaporator 160 and the value of the cross-sectional area thereof may be set in consideration of the pressure drop of the refrigerant along the length without disturbing the flow of the refrigerant.

즉, 상기 서브 증발기(160)의 길이가 1m 미만이면, 길이가 너무 짧아서 좌석(171) 및/또는 등받이(172) 모두에 균일한 냉방 효과를 얻기가 어렵게 된다.That is, if the length of the sub evaporator 160 is less than 1m, the length is too short, making it difficult to obtain a uniform cooling effect on both the seat 171 and / or the backrest 172.

상기 서브 증발기(160)의 길이가 9m를 초과하게 되면, 상기 서브 증발기(160)의 입구측과 출구측의 냉매의 압력차가 너무 커지게 되어 냉방 효과가 감소될 수 있으며, 이로 인해 균일한 냉방 효과를 얻기 어렵게 된다.When the length of the sub evaporator 160 exceeds 9m, the pressure difference between the refrigerant at the inlet side and the outlet side of the sub evaporator 160 becomes too large, thereby reducing the cooling effect, thereby providing a uniform cooling effect. It becomes difficult to obtain.

또한, 상기 서브 증발기(160)의 단면적이 0.8㎟ 미만이면, 냉매가 상기 서브 증발기(160)를 통과할 때, 상기 서브 증발기(160)의 입구측과 출구측 사이의 냉매 압력차가 너무 커지게 되어, 냉방 효과가 감소 또는 불균일해질 수 있다.In addition, when the cross-sectional area of the sub evaporator 160 is less than 0.8 mm 2, when the refrigerant passes through the sub evaporator 160, the refrigerant pressure difference between the inlet side and the outlet side of the sub evaporator 160 becomes too large. As a result, the cooling effect may be reduced or uneven.

상기 서브 증발기(160)의 단면적이 33㎟을 초과하게 되면, 차량의 좌석(171)에 앉는 탑승자가 이물감을 느낄 수 있고, 제조성이 떨어질 수 있다.When the cross-sectional area of the sub evaporator 160 exceeds 33 mm 2, the occupant sitting in the seat 171 of the vehicle may feel a foreign object, and the manufacturability may be deteriorated.

또한, 상기 서브 증발기(160)에서의 상기 냉매는 상기 서브 증발기(160)의 입구측으로부터 출구측으로 갈수록 압력이 강하되되, 상기 서브 증발기(160)의 입구측 압력을 5kg/㎠ 로 하였을 경우, 상기 서브 증발기(160)의 입구측 압력과 출구측 압력의 차이가 3.5kg/㎠ 이내이어야 한다.In addition, when the refrigerant in the sub-evaporator 160 has a pressure drop from the inlet side to the outlet side of the sub-evaporator 160, the inlet side pressure of the sub-evaporator 160 is 5 kg / cm 2, The difference between the inlet pressure and the outlet pressure of the sub evaporator 160 should be within 3.5 kg / cm 2.

상기 서브 증발기(160)의 입구측과 출구측 사이의 압력 차가 3.5kg/㎠를 초과하게 되면, 상기 차량의 좌석(171) 및/또는 좌석(171)의 등받이(172)에서의 균일한 냉방 효과를 얻기 어려우며, 이로 인해 전체적인 좌석(171) 및 등받이(172)에서의 냉방 효과가 현저히 떨어질 수 있다.When the pressure difference between the inlet side and the outlet side of the sub-evaporator 160 exceeds 3.5 kg / cm 2, uniform cooling effect in the seat 171 and / or the backrest 172 of the seat 171 of the vehicle It is difficult to obtain, which may significantly reduce the cooling effect on the overall seat 171 and the backrest 172.

한편, 도 4에 도시한 바와 같이, 상기 응축기(120)와 상기 서브 팽창 장치(150) 사이, 상기 서브 팽창 장치(150)와 상기 서브 증발기(160) 사이, 상기 서브 증발기(160)와 상기 압축기(110) 사이 중 어느 한 구간에 설치되어, 상기 서브 증발기(160)에서의 냉매유동을 선택적으로 차단하는 개폐기(180)가 더 구비될 수 있다.Meanwhile, as shown in FIG. 4, between the condenser 120 and the sub expansion device 150, between the sub expansion device 150 and the sub evaporator 160, the sub evaporator 160 and the compressor. Installed in any one of the sections 110, the switch 180 to selectively block the refrigerant flow in the sub-evaporator 160 may be further provided.

또한, 상기 계폐기(180)는, 도 5에 도시한 바와 같이, 상기 서브 증발기(160)의 입구측 또는 출구측에 인접하게 설치되어, 상기 서브 증발기(160)에서의 냉매 유동을 각 좌석별로 선택적으로 차단하도록 할 수도 있다. In addition, as illustrated in FIG. 5, the attenuator 180 is installed adjacent to the inlet side or the outlet side of the sub evaporator 160, and the refrigerant flow in the sub evaporator 160 is provided for each seat. You can also selectively block it.

상기 개폐기(180)의 조절에 의하여 상기 차량의 실내 냉방 시 탑승자는 좌석(171) 및/또는 등받이(172)로의 냉방을 허용하거나 차단할 수 있다.The passenger may allow or block cooling to the seat 171 and / or the backrest 172 when the vehicle is cooled indoors by adjusting the switch 180.

상기와 같은 구조의 차량용 공조 장치(100)는 다음과 같이 실내 냉방 및 좌석(171)과 등받이(172) 냉방이 이루어질 수 있다.In the vehicle air conditioner 100 having the above structure, indoor cooling and cooling of the seat 171 and the backrest 172 may be performed as follows.

상기 냉매는 압축기(110)에 의하여 고온 고압 상태가 되어 상기 응축기(120)로 보내어 진다.The refrigerant is a high temperature and high pressure state by the compressor 110 is sent to the condenser 120.

상기 응축기(120) 내에서는 열교환기에 의해 상기 냉매는 저온 고압 상태로 변환되고, 상기 팽창 장치(130)를 지나면서 압력이 낮아져 상기 증발기(140)로 보내어 진다.In the condenser 120, the refrigerant is converted into a low temperature and high pressure state by a heat exchanger, and the pressure is lowered while passing through the expansion device 130 and sent to the evaporator 140.

상기 증발기(140)에서는 상기 저온 저압 상태의 냉매와 상기 송풍기에 의하여 유입된 송풍 공기 사이에 열교환이 이루어져 차가워진 공기는 차량 실내의 냉방을 위해 공급된다.In the evaporator 140, the heat exchanged between the coolant in the low temperature and low pressure state and the blowing air introduced by the blower cools the air to be supplied for cooling the vehicle interior.

상기 송풍 공기와의 열교환이 이루어진 상기 냉매는 다시 상기 압축기(110)로 보내져 상기와 같은 순환이 다시 이루어진다.The refrigerant, which has undergone heat exchange with the blown air, is sent to the compressor 110 again, and the above circulation is repeated.

한편, 상기 응축기(120)에서 저온 고압의 상태로 변환된 상기 냉매 중 일부는 분기되어 상기 서브 팽창 장치(150)를 거쳐 차량의 좌석(171) 및/또는 상기 좌석(171)의 등받이(172)에 설치된 서브 증발기(160)를 통해 상기 압축기(110)로 보내질 수 있다.On the other hand, a portion of the refrigerant converted to the state of the low temperature and high pressure in the condenser 120 is branched through the sub-expansion device 150 and / or the backrest 172 of the seat 171 of the vehicle (171) It may be sent to the compressor 110 through a sub evaporator 160 installed in.

즉, 상기 저온 고압 상태로 상기 응축기(120)를 지난 냉매는 상기 서브 팽창 장치(150)를 지나면서 압력이 더 낮아져 보다 저온 상태로 상기 서브 증발기(160)로 보내어 진다.That is, the refrigerant passing through the condenser 120 in the low temperature and high pressure state is passed through the sub expansion device 150 to lower the pressure is sent to the sub evaporator 160 in a lower temperature state.

상기 서브 증발기(160)로 유입된 상기 냉매는 압력 강하가 이루어져 저온 상태로 상기 차량의 좌석(171) 및/또는 좌석(171)의 등받이(172)를 냉방할 수 있다.The refrigerant introduced into the sub-evaporator 160 may cool the backrest 172 of the seat 171 and / or the seat 171 of the vehicle at a low temperature due to a pressure drop.

즉, 요약하면, 상기 압축기(110)를 거쳐 상기 응축기(120)를 거친 냉매가, 일부는 상기 팽창 장치(130)를 거쳐 차량 실내의 냉방에 사용되도록 상기 증발기(140)에서 차량 실내의 열을 흡수하고, 나머지는 상기 서브 팽창 장치(150)를 거쳐 저온, 저압으로 변환되어 상기 서브 증발기(160)를 통해 차량 좌석(171) 및/또는 등받이(172)의 열을 흡수하는 것이다.That is, in summary, the refrigerant passing through the condenser 120 via the compressor 110 is partially cooled by the evaporator 140 so as to be used for cooling the vehicle interior via the expansion device 130. The rest is converted into low temperature and low pressure through the sub expansion device 150 to absorb heat of the vehicle seat 171 and / or backrest 172 through the sub evaporator 160.

아울러, 상기 팽창 장치(130)와 서브 팽창 장치(150)는 단순히 냉매량을 조절하는 역할 뿐만 아니라 고온, 고압의 냉매를 증발이 용이하도록 압력과 온도를 강하시키는 역할도 동시에 수행할 수 있는 팽창밸브로 구성함이 바람직할 것이다.In addition, the expansion device 130 and the sub-expansion device 150 is not only to control the amount of refrigerant but also to expand the pressure and temperature to facilitate the evaporation of the high-temperature, high-pressure refrigerant to facilitate the expansion valve at the same time It would be desirable to construct.

상기와 같은 구조의 차량용 공조 장치(100)에 의하면, 더운 날씨에 의해 상기 차량의 실내 온도가 상승한 경우, 차량 실내의 냉방뿐만 아니라 탑승자의 착석에 의해 냉기가 공급되지 않는 좌석(171) 및/또는 등받이(172)도 냉방할 수 있어 쾌적한 상태에서 운전을 할 수 있다.According to the vehicle air conditioner 100 having the above-described structure, when the indoor temperature of the vehicle is increased due to hot weather, the seat 171 and / or the cooling air is not supplied by not only the cooling of the vehicle interior but also the occupant's seating. The backrest 172 can also be cooled and can drive in a comfortable state.

보다 구체적으로 설명하면, 팽창 장치(130)를 거쳐 증발기(140)로 흐르는 냉매는 차량 실내의 냉방만을 담당하고, 서브 팽창 장치(150)를 거쳐 서브 증발기(160)로 흐르는 냉매는 좌석의 냉방만을 담당하므로, 사용자가 원하는 온도와 압력으로 냉매가 팽창 장치(130) 및 서브 팽창 장치(150)에서 각각 온도강하, 압력강하되어, 차량 실내 냉방과 좌석 냉방 온도를 조절할 수 있고, 좌석에 충분한 냉방효과를 가능하게 한다. More specifically, the refrigerant flowing through the expansion device 130 to the evaporator 140 is responsible only for cooling the vehicle interior, and the refrigerant flowing through the sub expansion device 150 to the sub evaporator 160 only cools the seat. Since it is in charge, the refrigerant is dropped in the expansion device 130 and the sub-expansion device 150 to the temperature and pressure desired by the user, respectively, so that the vehicle interior cooling and seat cooling temperature can be adjusted, and a sufficient cooling effect on the seat To make it possible.

즉, 본원발명의 냉매유동 구성은 차량 좌석 냉방을 위한 충분한 냉매의 양과 유동을 확보할 수가 있어서, 충분한 차량 좌석 냉방 효과를 달성할 수가 있다.That is, the refrigerant flow configuration of the present invention can secure the amount and flow of sufficient refrigerant for vehicle seat cooling, thereby achieving a sufficient vehicle seat cooling effect.

도 6는 본 발명의 또 다른 실시예에 따른 차량용 공조 장치를 개략적으로 나타낸 도면이다. 그리고, 도 7는 본 발명의 또 다른 실시예에 따른 좌석 냉방 유닛을 개략적으로 나타낸 도면이고, 도 8는 본 발명의 또 다른 일 실시예에 따른 좌석 냉방 유닛을 개략적으로 나타낸 도면이다. 6 is a view schematically showing a vehicle air conditioner according to another embodiment of the present invention. And, Figure 7 is a view schematically showing a seat cooling unit according to another embodiment of the present invention, Figure 8 is a view schematically showing a seat cooling unit according to another embodiment of the present invention.

도 6 내지 도 8를 참조하면, 차량용 공조 장치(100)는 실내 냉방 유닛(200) 및 좌석 냉방 유닛(300)을 포함한다.6 to 8, the vehicle air conditioner 100 includes an indoor cooling unit 200 and a seat cooling unit 300.

상기 실내 냉방 유닛(200)은 팽창된 냉매와 외부 공기 사이의 열교환에 의하여 차량 실내로 냉기를 공급한다.The indoor cooling unit 200 supplies cool air to the vehicle interior by heat exchange between the expanded refrigerant and the outside air.

상기 실내 냉방 유닛(200)은 폐쇄 회로 형태로서, 압축기(110)와, 응축기(120)와, 팽창 장치(130) 및 증발기(140)를 포함한다.The indoor cooling unit 200 has a closed circuit form and includes a compressor 110, a condenser 120, an expansion device 130, and an evaporator 140.

상기 실내 냉방 유닛(200)으로 공급되는 냉매는 상기 압축기(110)와, 상기 응축기(120)와, 상기 팽창 장치(130) 및 상기 증발기(140)를 순차적으로 이동해 저온 저압 상태로 변환되어 송풍기(미도시)에 유입된 외부 공기와 열교환을 통해 냉기를 차량 실내로 토출하고, 상기 냉매는 다시 상기 압축기(110)로 보내져 상기 과정을 반복한다.The refrigerant supplied to the indoor cooling unit 200 is sequentially moved to the compressor 110, the condenser 120, the expansion device 130, and the evaporator 140, and converted to a low temperature low pressure state to obtain a blower ( Cold air is discharged to the vehicle interior through heat exchange with external air introduced into the vehicle, and the refrigerant is sent back to the compressor 110 to repeat the process.

즉, 상기 실내 냉방 유닛(200)에서 상기 냉매는 압축기(110)에 의하여 고온 고압 상태가 되어 상기 응축기(120)로 보내진다.That is, in the indoor cooling unit 200, the refrigerant is sent to the condenser 120 at a high temperature and high pressure by the compressor 110.

상기 응축기(120) 내에서는 열교환기에 의해 상기 냉매는 저온 고압 상태로 변환되고, 상기 팽창 장치(130)를 지나면서 압력이 낮아져 상기 증발기(140)로 보내진다.In the condenser 120, the refrigerant is converted into a low temperature and high pressure state by a heat exchanger, and the pressure is lowered while passing through the expansion device 130 and sent to the evaporator 140.

상기 증발기(140)에서는 상기 저온 저압 상태의 냉매와 상기 송풍기에 의하여 유입된 송풍 공기 사이에 열교환이 이루어져 차가워진 공기는 차량 실내의 냉방을 위해 공급된다.In the evaporator 140, the heat exchanged between the coolant in the low temperature and low pressure state and the blowing air introduced by the blower cools the air to be supplied for cooling the vehicle interior.

상기 송풍 공기와의 열교환이 이루어진 상기 냉매는 다시 상기 압축기(110)로 보내져 상기와 같은 순환이 다시 이루어진다.The refrigerant, which has undergone heat exchange with the blown air, is sent to the compressor 110 again, and the above circulation is repeated.

또한, 상기 좌석 냉방 유닛(300)은 상기 좌석 냉방 유닛(300)을 순환하는 냉매의 온도 감소에 의하여 차량의 좌석(171) 및/또는 좌석(171)의 등받이(172)를 냉방한다.In addition, the seat cooling unit 300 cools the seat 171 of the vehicle and / or the backrest 172 of the seat 171 by reducing the temperature of the refrigerant circulating through the seat cooling unit 300.

상기 좌석 냉방 유닛(300)은 서브 압축기(111)와, 서브 응축기(121)와, 서브 팽창 장치(150) 및 서브 증발기(141)를 포함한다.The seat cooling unit 300 includes a sub compressor 111, a sub condenser 121, a sub expansion device 150, and a sub evaporator 141.

상기 좌석 냉방 유닛(300)에서도 상기 실내 냉방 유닛에서와 마찬가지로, 상기 좌석 냉방 유닛(300) 내를 순환하는 냉매가 서브 압축기(111)에 의해 고온 고압 상태로 변환되고, 서브 응축기(121)로 보내져 저온 고압 상태로 변환된 후, 상기 서브 팽창 장치(150)를 통과하면서 저온 저압 상태로 변환되어 서브 증발기(141)로 공급된다.In the seat cooling unit 300, as in the indoor cooling unit, the refrigerant circulating in the seat cooling unit 300 is converted into a high temperature and high pressure state by the sub compressor 111, and is sent to the sub condenser 121. After being converted to a low temperature and high pressure state, it is converted into a low temperature low pressure state while passing through the sub expansion device 150 and supplied to the sub evaporator 141.

상기 서브 증발기(141)로 유입된 저온 저압의 냉매는 상기 서브 증발기(141)를 통과하면서 압력 강하에 의해 온도가 더 내려가면서 다시 서브 압축기(111)로 보내져 상기의 과정이 되풀이될 수 있다.The low temperature low pressure refrigerant introduced into the sub evaporator 141 passes through the sub evaporator 141 and is further sent to the sub compressor 111 while the temperature is lowered due to the pressure drop, thereby repeating the above process.

즉, 차량의 실내를 냉방하기 위한 실내 냉방 유닛(200)과는 별도로 좌석 냉방을 위해 서브 압축기(111), 서브 응축기(121), 서브 팽창 장치(150), 서브 증발기(141)로 이루어진 좌석 냉방 유닛(300)을 추가로 구성하고, 상기 좌석 냉방 유닛(300)은 서브 압축기(111)와 서브 응축기(121)를 거친 냉매가 서브 팽창 장치(150)를 거쳐 저온, 저압으로 변환되어 좌석 냉방에만 사용되도록 서브 증발기(141)에만 공급되어, 좌석을 냉방하는 구조이다.That is, the seat cooling consisting of the sub compressor 111, the sub condenser 121, the sub expansion device 150, the sub evaporator 141 for cooling the seat separately from the indoor cooling unit 200 for cooling the interior of the vehicle. The unit 300 is further configured, and the seat cooling unit 300 converts the refrigerant passing through the sub compressor 111 and the sub condenser 121 into the low temperature and the low pressure through the sub expansion device 150 so that only the seat cooling is performed. It is supplied only to the sub evaporator 141 so as to be used, thereby cooling the seat.

한편, 상기 서브 증발기(141)의 경우, 관형 형태로 차량의 좌석(171) 및/또는 상기 좌석(171)의 등받이(172) 내에 설치되어 온도가 하강된 냉매에 의하여 차량의 좌석(171) 및/또는 등받이(172)에 냉방을 제공할 수 있다.On the other hand, in the case of the sub-evaporator 141, the seat 171 of the vehicle and the seat 171 and / or the back 172 of the seat 171 of the seat 171 in the tubular form of the vehicle 171 and And / or provide cooling to the backrest 172.

이 때, 상기 서브 증발기(141)는 차량 실내의 좌석(171) 혹은 등받이(172) 혹은 좌석(171)과 등받이(172) 모두에 설치될 수 있다.At this time, the sub evaporator 141 may be installed in the seat 171 or the backrest 172 or both the seat 171 and the backrest 172 of the vehicle interior.

상기 서브 증발기(141)는 그 길이가 1m ~ 9m 이내이고, 그 단면적은 0.8㎟ ~ 33㎟ 이내이다.The sub-evaporator 141 has a length of 1 m to 9 m or less, and a cross-sectional area of 0.8 mm 2 to 33 mm 2.

상기 단면적은 단면 형상에 관계없이 상기 서브 증발기(141)의 단면적을 의미하는 것으로, 상기 서브 증발기(141)의 전 범위에 걸쳐 상기 단면적은 0.8㎟ ~ 33㎟ 이내로 유지되어야 한다.The cross-sectional area means a cross-sectional area of the sub evaporator 141 regardless of the cross-sectional shape, and the cross-sectional area should be maintained within 0.8 mm 2 to 33 mm 2 over the entire range of the sub evaporator 141.

상기와 같은 서브 증발기(141)의 길이 및 그 단면적의 값은 상기 냉매의 흐름을 방해하지 않고, 길이에 따른 냉매의 압력 강하를 고려하여 설정될 수 있다.The length of the sub evaporator 141 and the value of the cross-sectional area of the sub evaporator 141 may be set in consideration of the pressure drop of the refrigerant along the length without disturbing the flow of the refrigerant.

즉, 상기 서브 증발기(141)의 길이가 1m 미만이면, 길이가 너무 짧아서 좌석(171) 및/또는 등받이(172) 모두에 균일한 냉방 효과를 얻기가 어렵게 된다.That is, when the length of the sub evaporator 141 is less than 1 m, the length is too short, making it difficult to obtain a uniform cooling effect on both the seat 171 and / or the backrest 172.

상기 서브 증발기(141)의 길이가 9m를 초과하게 되면, 상기 서브 증발기(141)의 입구측과 출구측의 냉매의 압력차가 너무 커지게 되어 냉방 효과가 감소될 수 있으며, 이로 인해 균일한 냉방 효과를 얻기 어렵게 된다.When the length of the sub evaporator 141 exceeds 9m, the pressure difference between the refrigerant at the inlet side and the outlet side of the sub evaporator 141 becomes too large, thereby reducing the cooling effect, thereby providing a uniform cooling effect. It becomes difficult to obtain.

또한, 상기 서브 증발기(141)의 단면적이 0.8㎟ 미만이면, 냉매가 상기 서브 증발기(141)를 통과할 때, 상기 서브 증발기(141)의 입구측과 출구측 사이의 냉매 압력차가 너무 커지게 되어, 냉방 효과가 감소 또는 불균일해질 수 있다.In addition, when the cross-sectional area of the sub evaporator 141 is less than 0.8 mm 2, the refrigerant pressure difference between the inlet side and the outlet side of the sub evaporator 141 becomes too large when the refrigerant passes through the sub evaporator 141. As a result, the cooling effect may be reduced or uneven.

상기 서브 증발기(141)의 단면적이 33㎟을 초과하게 되면, 차량의 좌석(171)에 앉는 탑승자가 이물감을 느낄 수 있고, 제조성이 떨어질 수 있다.When the cross-sectional area of the sub evaporator 141 exceeds 33 mm 2, the occupant sitting in the seat 171 of the vehicle may feel a foreign object, and the manufacturability may be deteriorated.

또한, 상기 서브 증발기(141)에서의 상기 냉매는 상기 서브 증발기(141)의 입구측으로부터 출구측으로 갈수록 압력이 강하되되, 상기 서브 증발기(141)의 입구측 압력을 5kg/㎠ 로 하였을 경우, 상기 서브 증발기(141)의 입구측 압력과 출구측 압력의 차이가 3.5kg/㎠ 이내이어야 한다.In addition, when the refrigerant in the sub evaporator 141 decreases in pressure from the inlet side to the outlet side of the sub evaporator 141, the inlet side pressure of the sub evaporator 141 is 5 kg / cm 2. The difference between the inlet pressure and the outlet pressure of the sub evaporator 141 should be within 3.5 kg / cm 2.

상기 서브 증발기(141)의 입구측과 출구측 사이의 압력 차가 3.5kg/㎠를 초과하게 되면, 상기 차량의 좌석(171) 및/또는 좌석(171)의 등받이(172)에서의 균일한 냉방 효과를 얻기 어려우며, 이로 인해 전체적인 좌석(171) 및 등받이(172)에서의 냉방 효과가 현저히 떨어질 수 있다.When the pressure difference between the inlet side and the outlet side of the sub-evaporator 141 exceeds 3.5 kg / cm 2, uniform cooling effect in the seat 171 of the vehicle and / or the backrest 172 of the seat 171. It is difficult to obtain, which may significantly reduce the cooling effect on the overall seat 171 and the backrest 172.

한편, 상기 서브 응축기(121)와 상기 서브 팽창 장치(150) 사이, 상기 서브 팽창 장치(150)와 상기 서브 증발기(141) 사이, 상기 서브 증발기(141)와 상기 서브 압축기(111) 사이 중 어느 한 구간에 설치되어, 상기 서브 증발기(141)에서의 냉매 유동을 선택적으로 차단하는 개폐기(180)가 더 구비될 수 있다.Meanwhile, any one of the sub condenser 121 and the sub expansion device 150, between the sub expansion device 150 and the sub evaporator 141, and between the sub evaporator 141 and the sub compressor 111. Installed in one section, the switch 180 to selectively block the refrigerant flow in the sub-evaporator 141 may be further provided.

다른 한편, 상기 서브 증발기(141)의 입구측 또는 출구측에 인접하게 설치되어, 상기 서브 증발기(141)에서의 냉매 유동을 각 좌석별로 선택적으로 차단하는 개폐기(180)가 더 구비될 수 있다. On the other hand, the switch 180 is installed adjacent to the inlet or outlet side of the sub-evaporator 141, may be further provided with a switch 180 to selectively block the refrigerant flow in the sub-evaporator 141 for each seat.

상기 개폐기(180)의 조절에 의하여 상기 차량의 실내 냉방 시 탑승자는 좌석(171) 및/또는 등받이(172)로의 냉방을 허용하거나 차단할 수 있다.The passenger may allow or block cooling to the seat 171 and / or the backrest 172 when the vehicle is cooled indoors by adjusting the switch 180.

상기와 같은 구조의 차량용 공조 장치(100)에 의하면, 더운 날씨에 의해 상기 차량의 실내 온도가 상승한 경우, 차량 실내의 냉방뿐만 아니라 탑승자의 착석에 의해 냉기가 공급되지 않는 좌석(171) 및/또는 등받이(172)도 냉방할 수 있어 쾌적한 상태에서 운전을 할 수 있다.According to the vehicle air conditioner 100 having the above structure, when the indoor temperature of the vehicle is increased due to hot weather, the seat 171 and / or the cooling air is not supplied by not only the cooling of the vehicle interior but also the occupant's seating. The backrest 172 can also be cooled and can drive in a comfortable state.

보다 구체적으로 설명하면, 팽창 장치(130)를 거쳐 증발기(140)로 흐르는 냉매는 차량 실내의 냉방만을 담당하고, 서브 팽창 장치(150)를 거쳐 서브 증발기(141)로 흐르는 냉매는 좌석의 냉방만을 담당하므로, 사용자가 원하는 온도와 압력으로 냉매가 팽창 장치(130) 및 서브 팽창 장치(150)에서 각각 온도강하, 압력강하되어, 차량 실내 냉방과 좌석 냉방 온도를 조절할 수 있고, 좌석에 충분한 냉방효과를 가능하게 한다. More specifically, the refrigerant flowing through the expansion device 130 to the evaporator 140 is responsible only for cooling the vehicle interior, and the refrigerant flowing through the sub expansion device 150 to the sub evaporator 141 only cools the seat. Since it is in charge, the refrigerant is dropped in the expansion device 130 and the sub-expansion device 150 by the temperature and pressure desired by the user, respectively, so that the vehicle interior cooling and seat cooling temperature can be adjusted, and sufficient cooling effect on the seat. To make it possible.

즉, 차량 좌석 냉방을 위한 충분한 냉매의 양과 유동을 확보할 수가 있어서, 충분한 차량 좌석 냉방 효과를 달성할 수가 있다.In other words, it is possible to ensure the amount and flow of sufficient refrigerant for cooling the vehicle seat, thereby achieving a sufficient vehicle seat cooling effect.
