Description

복합식 제습냉방시스템 {Hybrid dehumidified cooling system}Hybrid dehumidified cooling system
본 발명은 복합식 제습 냉방시스템에 관한 것으로, 보다 자세히는 잠열 및 현열 냉방부하를 효과적으로 처리함과 동시에 압축식 냉동사이클 및 액체식 제습사이클의 효율을 높이는 복합식 제습 냉방시스템에 관한것이다.The present invention relates to a complex dehumidification cooling system, and more particularly, to a combined dehumidification cooling system for effectively treating latent heat and sensible cooling loads while increasing the efficiency of a compression refrigeration cycle and a liquid dehumidification cycle.
일반적으로 압축식 냉방시스템은 압축기, 응축기, 팽창밸브, 증발기, 배관, 송풍기로 구성되어 증발기에서의 냉매 증발을 이용하여 처리공기로부터 열을 탈취하여 차가워진 처리공기로 건물의 냉방에 이용하고, 탈취된 열은 응축기를 통하여 외기로 방출되도록 사이클이 구성되어 있다.Generally, a compressed air cooling system is composed of a compressor, a condenser, an expansion valve, an evaporator, a pipe, and a blower, and uses heat of refrigerant from the process air to cool the building by using the refrigerant evaporation in the evaporator. The cycle is configured so that the heat is released to the outside air through the condenser.
그러나, 상기한 압축식 냉방시스템은 처리할 공기의 냉방부하 중 잠열부하가 늘어나게 되면 공기중의 수분을 응축시켜서 배출시키기 위해 실내에서 요구되는 쾌적한 공기온도보다 증발기 온도를 공기노점온도 이하로 과도하게 낮추어야 한다. 이로 인해 냉동사이클 효율감소 및 쾌적감 저하의 문제점이 발생할 수 있다.However, if the latent heat load is increased during the cooling load of the air to be treated, the compressed air cooling system must lower the evaporator temperature excessively below the air dew point temperature to the required air temperature in order to condense and discharge moisture in the air. do. This may cause problems of reduced refrigeration cycle efficiency and reduced comfort.
또한, 응축기에서는 외기를 이용하여 냉매가 응축할 때 발생되는 응축열을 배출하여야 하나 하절기에 외기온도가 높아질수록 냉매에서 열교환기를 통하여 외기로 열을 배출하기가 어려워지는 단점이 있다.In addition, the condenser must discharge the condensation heat generated when the refrigerant is condensed by using the outside air, but as the outside air temperature increases in the summer, it is difficult to discharge heat from the refrigerant to the outside through the heat exchanger.
액체 제습제를 사용하여 공기중의 수분 제거에 활용하는 액체 건조제 제습시스템은 제습부, 재생부, 용액 열교환기, 용액 펌프, 용액 분배기 및 건조제 용액의 비산으로 인한 손실을 방지하기 위한 엘리미네이터로 구성된다.Liquid desiccant dehumidification system that utilizes liquid dehumidifier to remove moisture from the air consists of dehumidifier, regenerator, solution heat exchanger, solution pump, solution distributor and eliminator to prevent loss due to scattering of desiccant solution. do.
이 액체 건조제 제습기는 공기 중의 수분에 대해 매우 큰 친화성을 갖고 있는 염화 리튬 수용액, 트리에틸렌글리콜 수용액, 염화 칼슘 수용액, 리튬 브로마이드 수용액 등의 액체 건조제를 이용하여 시스템의 제습부에서 처리공기와 직접 접촉시켜서 공기중의 수분을 제거하여 제습공기조화를 하는 것이다.This liquid desiccant dehumidifier is in direct contact with the process air in the dehumidifying part of the system by using liquid desiccants such as aqueous lithium chloride solution, triethylene glycol solution, calcium chloride solution, and lithium bromide solution which have a very high affinity for moisture in the air. It removes moisture in the air and makes dehumidification air conditioner.
액체 건조제 제습시스템의 작동은 액체 건조제의 증기압과 공기중 수증기 분압의 증기압력차를 수분 흡수 또는 배출의 물질 전달 구동력으로 하며, 제습용액으로 사용되는 액체 건조제의 증기압은 용액의 온도와 농도에 의존하게 된다.The operation of the liquid desiccant dehumidification system is the mass transfer driving force of water absorption or discharge of the vapor pressure of the liquid desiccant and the partial pressure of water vapor in the air, and the vapor pressure of the liquid desiccant used as the dehumidifying solution depends on the temperature and concentration of the solution. do.
액체 건조제 제습시스템에서 제습부에서의 공기제습과정 시 열 및 물질 전달능력 향상을 통해 제습기의 시스템 효율을 향상시키기 위해서는 공기와 액체 건조제와의 접촉면적 및 접촉시간의 증대가 중요하고, 액체 건조제로의 공기 중 수분 흡수 시에 발생되는 응축잠열, 흡수열 등의 제거를 통한 등온제습이 제습기 시스템 효율향상에 중요한 역할을 하게 된다.In the liquid desiccant dehumidification system, in order to improve the efficiency of the dehumidifier system by improving the heat and mass transfer capacity during the air dehumidification process in the dehumidifier, it is important to increase the contact area and the contact time between the air and the liquid desiccant, Isothermal dehumidification through the removal of latent heat of condensation and heat of absorption generated during moisture absorption in the air plays an important role in improving the efficiency of the dehumidifier system.
제습부에서 공기 중의 수분을 흡수하여 묽어진 제습용액은 재생부에서 용액을 가열하여 재생공기로 수분을 배출시킴으로써 다시 농용액으로 바뀌어 재사용할 수 있게 된다. 현재 액체 건조제 제습기는 정밀한 습도제어 또는 저습도가 요구되는 산업용 공기조화 분야에 많이 적용되고 있다.The dehumidifying solution diluted by absorbing the moisture in the air from the dehumidifying unit can be reused by converting it into a concentrated solution by heating the solution in the regenerating unit and discharging the moisture into the regenerating air. Currently, liquid desiccant dehumidifiers are widely applied to industrial air conditioners requiring precise humidity control or low humidity.
본 발명의 발명자는 이미 등록특허공보(10-208627호)에서 복합식 공기열원히트펌프를 이용한 냉난방 시스템에 대해 제안하였다. 상기 발명은 한대의 기기로서 건물의 냉방, 난방, 제습, 가습의 공기조화를 동시에 수행하는 복합식 공기열원 히트펌프를 이용한 냉난방 기기에 관한 것으로 실내기의 압축 사이클은 증발기, 제습용액 사이클은 제습기로 가동되고, 실외기의 압축사이클은 응축기, 제습용사이클은 재생기로 가동되며 흡수제습과 현열냉방이 동시에 가동되는 복합식 공기열원 히트펌프를 이용한 냉난방기기이다.The inventor of the present invention has already proposed a cooling and heating system using a combined air heat source heat pump in the Patent Publication (10-208627). The present invention relates to a cooling and heating device using a complex air heat source heat pump that simultaneously performs air conditioning of cooling, heating, dehumidification, and humidification of a building as a single device. The compression cycle of the indoor unit is operated by an evaporator, and the dehumidification solution cycle by a dehumidifier. In the outdoor unit, the compression cycle of the outdoor unit is a condenser and the dehumidification cycle is a regenerator. It is a heating and cooling system using a combined air heat source heat pump that simultaneously operates absorption dehumidification and sensible cooling.
또한 등록실용신안공보(20-300297호)에서는 액체제습식 히트펌프를 이용한 냉방장치로서 상기 10-208627호과 마찬가지로 재생기와 제습냉각기를 구비하고 압축사이클의 응축기를 통과한 고온용액이 상기 재생기에서 재생되고 증발기를 통과한 저온용액으로 흡수식 제습을 하게 된다. In addition, the Korean Utility Model Publication (20-300297) is a cooling device using a liquid dehumidification type heat pump, as in the case of 10-208627, a high temperature solution having a regenerator and a dehumidification cooler and passing through a condenser of a compression cycle is regenerated in the regenerator. Absorbent dehumidification is carried out with the low temperature solution passed through the evaporator.
그러나 이러한 압축식 냉방시스템과 액체 건조제 제습시스템을 단순히 결합해서는 압축식 냉방시스템의 응축기 배열을 충분히 활용하기 어려워 제습희용액의 재생에 충분한 온도까지 상승시키기 어렵고, 냉각부, 제습 재생충전탑 등이 별도로 위치하게 되어 시스템의 크기가 커지는 문제점이 있으므로 이에 대한 해결책이 필요하다.However, simply combining the compressed air cooling system and the liquid desiccant dehumidification system makes it difficult to fully utilize the condenser arrangement of the compressed air cooling system, making it difficult to raise the temperature sufficient to regenerate the dehumidifying solution. There is a problem in that the size of the system is large because it is located there is a need for a solution.
본 발명이 이루고자 하는 기술적 과제는 상기한 문제점을 해결하기 위해 구현된 것으로 압축식 냉방시스템과 액체 건조제를 이용하는 액체식 제습기의 장점을 결합하여 냉방과 제습을 동시에 수행하는 효율적인 복합식 제습 냉방시스템을 제공하되, 상기 복합식 제습 냉방시스템은 응축부를 과열증기응축부와 포화증기 응축부로 구분하여 과열증기 응축부에서 재생에 필요한 온도까지 충분히 상승할 수 있도록 하였다.The technical problem to be achieved by the present invention is to solve the above problems to provide an efficient combined dehumidification cooling system that performs the cooling and dehumidification at the same time by combining the advantages of the compressed air cooling system and the liquid dehumidifier using a liquid desiccant In addition, the combined dehumidification and cooling system divides the condensation unit into a superheated steam condensation unit and a saturated steam condensation unit so as to sufficiently increase the temperature required for regeneration in the superheated steam condensation unit.
본 발명의 다른 목적은 압축식 냉방시스템의 압축기 출구 측의 고온, 고압의 냉매 배열을 이용하여 액체 제습용액을 재생함과 동시에 액체 제습용액을 이용한 압축 냉방시스템 재생기의 저온희용액을 예열하는 동시에 고온 농용액을 예냉하여 제습시스템의 효율을 향상하는 것이다. Another object of the present invention is to regenerate the liquid dehumidification solution by using a high-temperature, high-pressure refrigerant arrangement on the compressor outlet side of the compressed air cooling system, and at the same time to preheat the low temperature solution of the compressed air cooling system regenerator using the liquid dehumidifying solution. Precooling the agricultural solution to improve the efficiency of the dehumidification system.
