Description

제습 장치{DEHUMIDIFYING DEVICE}Dehumidifying device {DEHUMIDIFYING DEVICE}

본 발명은, 제습 로터 및 히트 펌프를 이용하는 것으로서, 단일 로터로 재생 히터의 소비 전력을 삭감한 저노점(低露点) 공기의 공급이 가능한 제습 시스템에 관한 것이다.The present invention relates to a dehumidification system using a dehumidifying rotor and a heat pump, and capable of supplying low dew point air with reduced power consumption of a regenerative heater using a single rotor.

최근, 리튬 전지의 수요가 증대하고, 그에 따라 그 생산도 증대하고 있다. 리튬 전지는, 그 원료인 리튬이 공기 중의 습기와 반응하고, 그 반응에 의하여 생산된 리튬 전지의 성능이 나빠진다. 이 때문에, 리튬 전지의 생산 라인은, 건조한 상태로 유지할 필요가 있다. 이 건조한 상태로 유지하는 수단으로서, 생산 공장 내를 건조한 질소에 의하여 퍼지하는 수단과, 실리카 젤 등의 습기 흡착제를 갖는 제습 로터를 이용한 제습 장치를 이용하는 수단 등이 있다.In recent years, demand for lithium batteries has increased, and their production has also increased accordingly. In a lithium battery, lithium as a raw material reacts with moisture in the air, and the reaction deteriorates the performance of the produced lithium battery. For this reason, it is necessary to keep the production line of a lithium battery dry. Means for maintaining this dry state include means for purging the inside of the production plant with dry nitrogen, means for using a dehumidifying device using a dehumidifying rotor having a moisture adsorbent such as silica gel, and the like.

리튬 전지의 용도가, 전기 자동차나 하이브리드 자동차 등의 자동차용으로 확산됨에 따라, 생산 공장의 규모가 커져, 제습 장치를 이용하는 수단 쪽이 다수 채용되고 있다.As the use of lithium batteries spreads to automobiles such as electric vehicles and hybrid vehicles, the scale of production plants increases, and means using dehumidifiers are being adopted in large numbers.

제습 장치의 경우, 제습 로터의 재생에 고온의 공기를 사용하는 것이지만, 그 고온의 공기를 만들기 위한 에너지를 가능한 한 적게 하는 것이 도모되고 있다.In the case of a dehumidifying device, high-temperature air is used to regenerate the dehumidifying rotor, but it is intended to reduce the energy required to generate the high-temperature air as much as possible.

예를 들면 특허문헌 1에 개시된 것은, 재생 온도가 섭씨 50℃(이하, 온도는 모두 "섭씨"로 한다.)로 낮아도, 2단의 제습 로터로 초저노점의 건조 공기를 공급하는 제습 장치이며, 쿨러에 히트 펌프의 증발기만을 이용하고, 히터에 히트 펌프의 응축기만을 이용함으로써, 제습 로터의 재생을 위하여 다른 열원을 필요로 하지 않기 때문에, 에너지 절약이다.For example, what is disclosed in Patent Literature 1 is a dehumidifying device that supplies ultra-low dew point dry air with a two-stage dehumidifying rotor even when the regeneration temperature is as low as 50° C. (hereinafter, all temperatures are referred to as “Celsius”). Since only the evaporator of the heat pump is used as the cooler and only the condenser of the heat pump is used as the heater, no other heat source is required for regeneration of the dehumidifying rotor, so energy is saved.

일본 특허공보 제6251311호Japanese Patent Publication No. 6251311

상기 특허문헌 1에 개시된 것은, 저온 재생으로 초저노점의 건조 공기를 공급하는 제습 장치로서, 히트 펌프의 증발기와 응축기만을 사용하여, 공조기 전체의 에너지 부하를 경감할 수 있도록 하고 있다. 즉, 1대의 증발기(제2 쿨러)에 대하여, 4대의 응축기(제1 내지 제3 히터 및 방열용 응축기)를 배치하고, 단일 냉각기의 응축열로서 얻어지는 저온재열을 이용하여, 에너지 절약 효과를 얻고 있다. 그러나, 응축기가 4대 있고, 제습 로터도 2개 있기 때문에, 이니셜 코스트가 높으며, 장치가 커진다.The patent document 1 discloses a dehumidifying device for supplying dry air with an ultra-low dew point through low-temperature regeneration, and uses only an evaporator and a condenser of a heat pump to reduce the energy load of the entire air conditioner. That is, four condensers (first to third heaters and heat dissipation condensers) are arranged for one evaporator (second cooler), and energy saving effect is obtained by using low-temperature reheat obtained as condensation heat of a single cooler. . However, since there are four condensers and two dehumidifying rotors, the initial cost is high and the device becomes large.

통상, 단일 제습 로터를 이용하여, 저노점 공기를 공급하기 위해서는, 재생 온도를 100℃ 이상까지 승온시킬 필요가 있기 때문에, 재생 열원으로서 전기 히터나 증기 히터 등을 사용하여, 재생 온도를 올릴 필요가 있다.Normally, in order to supply low dew point air using a single dehumidifying rotor, it is necessary to raise the regeneration temperature to 100°C or higher, so it is necessary to raise the regeneration temperature using an electric heater or steam heater as a regeneration heat source. there is.

본 발명은 상기 과제를 해소하기 위하여 이루어진 것으로, 단일 제습 로터 및 캐스케이드식 히트 펌프를 이용함으로써, 최대 110℃까지 재생 온도를 높일 수 있으므로, 단일 제습 로터를 이용하여 저노점 공기를 공급할 수 있고, 단일 제습 로터로 제습 로터의 재생에 전기 히터 등을 이용하는 종래의 제습 장치에 비하여 에너지 절약이며, 특허문헌 1과 같은 2단의 제습 로터로 히트 펌프만을 이용하는 제습 장치에 비하여 이니셜 코스트가 억제된 제습 장치를 제공하는 것을 목적으로 한다.The present invention has been made to solve the above problems, and since the regeneration temperature can be increased up to 110 ° C. by using a single dehumidifying rotor and a cascade heat pump, low dew point air can be supplied using a single dehumidifying rotor, Compared to a conventional dehumidification device using an electric heater or the like for regeneration of the dehumidification rotor as a dehumidification rotor, energy saving, and a dehumidification device with reduced initial cost compared to a dehumidification device using only a heat pump with a two-stage dehumidification rotor such as Patent Document 1 intended to provide

본 발명의 제습 장치는, 고온의 응축열을 제습 장치의 재생 열원으로서 이용함으로써, 단일 제습 로터로 저노점 공기를 공급 가능하게 했으므로, 장치가 보다 콤팩트해지고, 이니셜 코스트를 낮게 억제할 수 있어, 리튬 전지 공장 등의 현장에 설치가 용이한 것이 된다.In the dehumidifying device of the present invention, low dew point air can be supplied with a single dehumidifying rotor by using high-temperature condensation heat as a regenerative heat source of the dehumidifying device, so that the device is more compact, the initial cost can be kept low, and the lithium battery It becomes easy to install on site, such as a factory.

또한, 캐스케이드식 히트 펌프로 함으로써, 응축기와 증발기의 사이의 고저차압을 충분히 확보할 수 있고, 그 결과, 쌍방의 능력을 충분히 얻을 수 있다. 이로써, 단일 제습 로터로 제습 로터의 재생에 전기 히터를 이용하는 종래의 제습 장치에 비하여, 약 20%의 에너지를 삭감할 수 있으므로, 러닝 코스트도 억제할 수 있다.In addition, by setting it as a cascade type heat pump, it is possible to sufficiently secure a high and low differential pressure between the condenser and the evaporator, and as a result, sufficient capabilities of both can be obtained. As a result, since energy can be reduced by about 20% with a single dehumidifying rotor compared to a conventional dehumidifying device using an electric heater for regeneration of the dehumidifying rotor, running cost can also be suppressed.

도 2에 본 발명의 냉매 플로를 나타낸다. 본 발명의 냉매 플로는, 제1 히터(7)(응축기(12)) 및 제2 쿨러(6)(증발기(13)) 각각을 다른 2개의 냉매 플로(제1 냉매 플로(14) 및 제2 냉매 플로(18))로서 구성하고, 각각의 냉매 플로에 압축기를 배치하여, 일방의 압축기(제1 압축기(15))의 냉매의 증발, 및 다른 일방의 압축기(제2 압축기(19))의 냉매의 응축은, 쌍방의 사이에 마련한 캐스케이드 콘덴서(17)에 의하여 행하며, 응축기(12)의 고온의 응축열을 제습 로터(1)의 재생용 공기의 가열의 열원으로서 이용하는 것을 특징으로 한다(이하, "캐스케이드식 히트 펌프"라고 한다.).2 shows the refrigerant flow of the present invention. The refrigerant flow of the present invention separates the first heater 7 (condenser 12) and the second cooler 6 (evaporator 13) into two other refrigerant flows (the first refrigerant flow 14 and the second The refrigerant flow 18) is configured, and a compressor is disposed in each refrigerant flow so that the refrigerant is evaporated in one compressor (first compressor 15) and the other compressor (second compressor 19) The condensation of the refrigerant is performed by a cascade condenser 17 provided between the two sides, and the high-temperature condensation heat of the condenser 12 is used as a heat source for heating the regeneration air of the dehumidifying rotor 1 (hereinafter, It is called "Cascade Heat Pump").

제1 냉매 플로(14)에는, 제1 압축기(15), 재생용 공기를 가열하는 제1 히터(7)로서의 응축기(12), 팽창 수단으로서의 팽창 밸브(16), 캐스케이드 콘덴서(17)가 순서대로 접속되어 있다. 제1 압축기(15)로부터 나오는 가스화된 냉매는, 응축기(12)로 유입되고, 재생용 공기를 가열하여 응축한다. 응축기(12)로부터 토출한 액화된 냉매는 팽창 밸브(16)로 감압 팽창되어, 캐스케이드 콘덴서(17)에 유입된다. 캐스케이드 콘덴서(17)에서는, 제1 냉매 플로(14)의 냉매와 제2 냉매 플로(18)의 냉매가 열교환되고, 제1 냉매 플로(14)의 냉매는 증발함과 함께, 제2 냉매 플로(18)의 냉매는 응축한다. 이로써, 제1 냉매 플로(14)의 냉매는, 캐스케이드 콘덴서(17)에 의하여 재생용 공기를 가열하기 위하여 필요한 열을 흡수하여 증발하고, 제1 압축기(15)로 되돌아가 압축되어, 순환계를 형성한다. 제1 냉매 플로(14)에 이용하는 냉매에는, 고온에서 보다 많은 응축열이 얻어지는 특성을 가진 냉매를 사용한다. 이 때문에, 제1 히터(7)(응축기(12))에서는 재생용 공기를 최대 110℃까지 가열할 수 있다.In the first refrigerant flow 14, a first compressor 15, a condenser 12 as a first heater 7 for heating air for regeneration, an expansion valve 16 as an expansion means, and a cascade condenser 17 are provided in this order. connected as is. The gasified refrigerant discharged from the first compressor 15 flows into the condenser 12 and heats and condenses the air for regeneration. The liquefied refrigerant discharged from the condenser 12 is depressurized and expanded by the expansion valve 16, and flows into the cascade condenser 17. In the cascade condenser 17, the refrigerant in the first refrigerant flow 14 and the refrigerant in the second refrigerant flow 18 exchange heat, the refrigerant in the first refrigerant flow 14 evaporates, and the second refrigerant flow ( The refrigerant in 18) condenses. As a result, the refrigerant in the first refrigerant flow 14 absorbs heat necessary for heating the air for regeneration by the cascade condenser 17, evaporates, returns to the first compressor 15, and is compressed to form a circulation system. do. As the refrigerant used in the first refrigerant flow 14, a refrigerant having a characteristic of obtaining more condensation heat at a high temperature is used. For this reason, in the 1st heater 7 (condenser 12), the air for reproduction|regeneration can be heated up to 110 degreeC.

제2 냉매 플로(18)에는, 제2 압축기(19), 캐스케이드 콘덴서(17), 응축 압력 조정용의 보조 콘덴서 등의 열밸런스 조정 장치, 팽창 수단으로서의 팽창 밸브(20), 드라이 룸(11)으로부터의 환기(RA)를 냉각하는 제2 쿨러(6)로서의 증발기(13)가 순서대로 접속되어 있다. 제2 압축기(19)로부터 나오는 가스화된 냉매는, 캐스케이드 콘덴서(17)에 유입된다. 캐스케이드 콘덴서(17)에서는, 제2 냉매 플로(18)의 냉매가 제1 냉매 플로(14)의 냉매로 방열하여 응축한다. 캐스케이드 콘덴서(17)로부터 토출한 액화된 냉매는 팽창 밸브(20)로 감압 팽창되어, 증발기(13)에 유입되며, 드라이 룸(11)으로부터의 환기(RA)를 냉각하여, 제2 압축기(19)로 되돌아가 압축되는 순환계를 형성한다.In the second refrigerant flow 18, a second compressor 19, a cascade condenser 17, a heat balance adjusting device such as an auxiliary condenser for adjusting the condensation pressure, an expansion valve 20 as an expansion means, and a dry room 11 The evaporator 13 as the 2nd cooler 6 which cools the ventilation RA of is connected in order. The gasified refrigerant discharged from the second compressor (19) flows into the cascade condenser (17). In the cascade condenser 17, the refrigerant in the second refrigerant flow 18 dissipates heat to the refrigerant in the first refrigerant flow 14 and condenses. The liquefied refrigerant discharged from the cascade condenser 17 is reduced and expanded by the expansion valve 20, flows into the evaporator 13, cools the ventilation RA from the dry room 11, and the second compressor 19 ) to form a compressed circulatory system.

이와 같이, 제1 히터(7)로서의 응축기(12)가 접속되는 제1 냉매 플로(14)와, 제2 쿨러(6)로서의 증발기(13)가 접속되는 제2 냉매 플로(18)가, 캐스케이드 콘덴서(17)를 개재하여 서로 접속되어, 캐스케이드식 히트 펌프가 구성된다. 이로써, 응축기(12)의 응축 압력과, 증발기(13)의 증발 압력의 차를 충분히 확보할 수 있다. 그 결과, 응축기(12)에서의 재생용 공기의 가열 능력이 커지고, 또한 증발기(13)의 냉각 능력도 커진다.In this way, the first refrigerant flow 14 connected to the condenser 12 as the first heater 7 and the second refrigerant flow 18 connected to the evaporator 13 as the second cooler 6 form a cascade They are connected to each other via a condenser 17 to form a cascade heat pump. In this way, the difference between the condensation pressure of the condenser 12 and the evaporation pressure of the evaporator 13 can be sufficiently secured. As a result, the heating capacity of the regeneration air in the condenser 12 increases, and the cooling capacity of the evaporator 13 also increases.

상술한 캐스케이드식 히트 펌프와는 별도로, 제1 쿨러(5)는, 외기(OA) 등의 처리용 공기의 변동이 있기 때문에, 단독의 냉동기를 이용한다. 제2 히터(8)에는 급기(SA)의 온도 조절로서, 전기 히터를 이용한다. 제1 히터(7)에는 응축기(12)의 응축열을 이용하여 재생용 공기를 최대 110℃까지 가열하지만, 제1 히터(7)의 후단에 보조 히터를 설치하여, 제1 히터(7)로 가열이 부족할 경우에는 이 보조 히터로 원하는 재생 온도까지 가열하도록 해도 된다.Apart from the cascade type heat pump described above, the first cooler 5 uses a single refrigerator because there is variation in processing air such as outside air (OA). An electric heater is used for the second heater 8 as a temperature control of the supply air SA. The first heater 7 uses the condensation heat of the condenser 12 to heat the regeneration air up to 110°C, but an auxiliary heater is installed at the rear end of the first heater 7 to heat it with the first heater 7. If this is insufficient, the auxiliary heater may be used to heat to a desired regeneration temperature.

상기 실시예에서는, 처리 존과 재생 존, 퍼지 존으로 3분할한 제습 로터를 사용했지만, 흡착 존과 재생 존으로 2분할한 제습 로터를 사용하고, 재생용 공기로서 처리 존을 통과한 공기, 외기, 공급처로부터의 환기 중 적어도 하나로 구성되는 공기를 이용하도록 해도 된다. 또, 제습 로터의 처리 존을 통과하기 전 혹은 통과한 후의 공기를 퍼지 존에 통과시켜, 재생 존을 통과시키기 전의 재생용 공기에 혼합하도록 해도 된다. 또, 3분할 이상으로 분할한 제습 로터를 이용한 플로로 해도 된다.In the above embodiment, the dehumidification rotor divided into three zones, a treatment zone, a regeneration zone, and a purge zone, was used, but a dehumidification rotor divided into two zones, an adsorption zone and a regeneration zone, was used, and air passed through the treatment zone as regeneration air, outside air , air composed of at least one of ventilation from a supply source may be used. Alternatively, the air before or after passing through the processing zone of the dehumidifying rotor may be passed through the purge zone and mixed with the air for regeneration before passing through the regeneration zone. Moreover, it is good also as a flow using the dehumidifying rotor divided into 3 divisions or more.

또, 상기 실시예에서는, 제1 쿨러(5)에는 단독의 냉동기를 이용하도록 했지만, 제1 쿨러(5)는 제2 쿨러(6)과 함께 제2 냉매 플로(18)의 증발기(13)를 이용하도록 해도 된다. 즉, 증발기(13)의 증발열을 제1 쿨러(5) 및 제2 쿨러(6)에서 이용할 수 있도록, 증발기(13)로부터의 배관을 각각의 쿨러에 연결되도록 설치하거나, 제1 쿨러(5) 및 제2 쿨러(6)에는 각각 다른 증발기를 이용하여, 제2 냉매 플로(18)에 증발기를 2개 마련하고, 이들 2개의 증발기를 직렬 또는 병렬이 되도록 배치하는 것을 들 수 있지만, 이에 한정되는 것은 아니다.Further, in the above embodiment, a single refrigerator is used for the first cooler 5, but the first cooler 5 uses the evaporator 13 of the second refrigerant flow 18 together with the second cooler 6. you can make use of it. That is, pipes from the evaporator 13 are installed to be connected to each cooler so that the evaporation heat of the evaporator 13 can be used by the first cooler 5 and the second cooler 6, or the first cooler 5 And using different evaporators for the second cooler 6, providing two evaporators in the second refrigerant flow 18, and arranging these two evaporators in series or parallel, but are limited thereto It is not.

또한, 제1 쿨러(5)에만 제2 냉매 플로(18)의 증발기(13)를 이용하고, 제2 쿨러(6)에는 단독의 냉동기를 이용하도록 해도 된다. 또한, 본 실시예에서는, 제2 쿨러(6)의 증발열 쪽이 제1 히터(7)의 응축열보다 출력이 커서, 캐스케이드 콘덴서(17)에서의 열교환으로는 충분하지 않게 되는 경우가 있기 때문에, 제2 냉매 플로(18)에 응축기로서 보조 콘덴서를 마련하도록 했지만, 이에 한정하는 것은 아니며, 제2 냉매 플로(18)에는 보조 콘덴서 등의 열밸런스 조정 장치 등을 마련하지 않아도 된다.Alternatively, the evaporator 13 of the second refrigerant flow 18 may be used only for the first cooler 5, and a single refrigerator may be used for the second cooler 6. In addition, in this embodiment, since the output of the heat of evaporation of the second cooler 6 is greater than the heat of condensation of the first heater 7, heat exchange in the cascade condenser 17 may not be sufficient. Although an auxiliary condenser is provided as a condenser in the second refrigerant flow 18, it is not limited thereto, and a heat balance adjusting device such as an auxiliary condenser may not be provided in the second refrigerant flow 18.

상기 실시예와 같이 제2 히터(8)에는 전기 히터가 아니라, 제1 히터(7)와 함께 제1 냉매 플로(14)의 응축기(12)를 이용하도록 해도 된다. 즉, 응축기(12)의 응축열을 제1 히터(7) 및 제2 히터(8)에서 이용할 수 있도록, 응축기(12)로부터의 배관을 각각의 히터에 연결되도록 설치하거나, 제1 히터(7) 및 제2 히터(8)에는 각각 다른 응축기를 이용하여, 제1 냉매 플로(14)에 응축기를 2개 마련하고, 이들 2개의 응축기를 직렬 또는 병렬이 되도록 배치하는 것을 들 수 있지만, 이에 한정되는 것은 아니다.As in the above embodiment, the condenser 12 of the first refrigerant flow 14 may be used as the second heater 8 together with the first heater 7 instead of an electric heater. That is, pipes from the condenser 12 are installed to be connected to each heater so that the condensation heat of the condenser 12 can be used by the first heater 7 and the second heater 8, or the first heater 7 and using different condensers for the second heater 8, providing two condensers in the first refrigerant flow 14, and arranging these two condensers in series or in parallel, but are limited thereto It is not.

이상의 구성에 의하여, 캐스케이드식 히트 펌프에 있어서의 응축기를 재생용 공기의 가열의 열원으로서 이용함으로써, -60℃ DP 이하의 저노점 공기를 공급함과 함께, 110℃까지 승온할 때의 열에너지가 삭감된다.With the above configuration, by using the condenser in the cascade heat pump as a heat source for heating the air for regeneration, low dew point air of -60°C DP or lower is supplied, and thermal energy when the temperature is raised to 110°C is reduced. .

본 발명의 제습 장치에 의하면, 예를 들면, 2인용 드라이 룸을 -40℃ DP 이하로 유지하기 위한 기기로 하여 비교한 경우, 단일 제습 로터로 제습 로터의 재생에 전기 히터만을 이용하는 종래의 제습 장치에 비하여, 약 20%의 에너지를 삭감할 수 있다.According to the dehumidifying device of the present invention, when compared with, for example, a device for maintaining a dry room for two people at -40° C. DP or lower, a single dehumidifying rotor is a conventional dehumidifying device using only an electric heater for regeneration of the dehumidifying rotor. In comparison, about 20% of energy can be reduced.

이상과 같이, 단일 제습 로터를 이용하여, 캐스케이드식 히트 펌프를 채용하고 응축기의 응축열을 재생용 공기의 가열에 이용함으로써, 에너지 절약으로 이니셜 코스트가 억제된 초저노점 제습 장치로 할 수 있다.As described above, by adopting a cascade type heat pump using a single dehumidifying rotor and using the condensation heat of the condenser to heat the air for regeneration, an ultra-low dehumidifying device with low initial cost and energy saving can be obtained.

저노점의 공기를 공급할 수 있어, 리튬 전지의 공장이나, 제약의 공정에도 적용할 수 있다.Low dew point air can be supplied, and it can be applied to lithium battery factories and pharmaceutical processes.
